pid label text 4186249 1 Searching and capturing a character using regular expressions Python

While going through one of the problems in Python Challenge, I am trying to solve it as follows:

Read the input in a text file with characters as follows:

DQheAbsaMLjTmAOKmNsLziVMenFxQdATQIjItwtyCHyeMwQTNxbbLXWZnGmDqHhXnLHfEyvzxMhSXzd BEBaxeaPgQPttvqRvxHPEOUtIsttPDeeuGFgmDkKQcEYjuSuiGROGfYpzkQgvcCDBKrcYwHFlvPzDMEk MyuPxvGtgSvWgrybKOnbEGhqHUXHhnyjFwSfTfaiWtAOMBZEScsOSumwPssjCPlLbLsPIGffDLpZzMKz jarrjufhgxdrzywWosrblPRasvRUpZLaUbtDHGZQtvZOvHeVSTBHpitDllUljVvWrwvhpnVzeWVYhMPs kMVcdeHzFZxTWocGvaKhhcnozRSbWsIEhpeNfJaRjLwWCvKfTLhuVsJczIYFPCyrOJxOPkXhVuCqCUgE luwLBCmqPwDvUPuBRrJZhfEXHXSBvljqJVVfEGRUWRSHPeKUJCpMpIsrV.......

What I need is to go through this text file and pick all lower case letters that are enclosed by only three upper-case letters on each side.

The python script that I wrote to do the above is as follows:

import re pattern = re.compile("[a-z][A-Z]{3}([a-z])[A-Z]{3}[a-z]") f = open('/Users/Dev/Sometext.txt','r') for line in f: result = pattern.search(line) if result: print result.groups() f.close()

The above given script, instead of returning the capture(list of lower case characters), returns all the text blocks that meets the regular expression criteria, like

aXCSdFGHj vCDFeTYHa nHJUiKJHo ......... .........

Can somebody tell me what exactly I am doing wrong here? And instead of looping through the entire file, is there an alternate way to run the regular expression search on the entire file?

Thanks

Yes, of course there is :-) object oriented techniques are a tool ... if you use the wrong tool for a given job, you will be over complicating things (think spoon when all you need is a knife).

To me, I judge "how much" by the size and scope of the project. If it is a small project, sometimes it does add too much complexity. If the project is large, you will still be taking on this complexity, but it will pay for itself in ease of maintainability, extensibility, etc.

Assuming that's VB.Net, you need to escape the ):

If Regex.IsMatch(Output, "\b" & "Serial\)" & "\b") Then 'do something End If

In .Net regular expressions, parentheses are the grouping characters.

If, as you say, the word 'Serial)' is generated dynamically, you will have to escape it before passing it to the RE engine:

If Regex.IsMatch(Output, "\b" & Regex.Escape("Serial)") & "\b") Then 'do something End If

As one other answerer has posted, this won't match "Serial) xyz" (for example) since there's no \b between the ) and space (\b only exists between \w and \W characters and both ) and a space are \W).

You may have to resort to an ugly hack like:

If Regex.IsMatch(Output, "\s" & Regex.Escape("Serial)") & "\s") _ Or Regex.IsMatch(Output, "\s" & Regex.Escape("Serial)") & "$") _ Or Regex.IsMatch(Output, "^" & Regex.Escape("Serial)") & "\s") _ Or Regex.IsMatch(Output, "^" & Regex.Escape("Serial)") & "$") _ Then 'do something End If

I thought that maybe you could match a character class consisting of (^ or $) and \s along the lines of:

If Regex.IsMatch(Output, "[\s^]" & Regex.Escape("Serial)") & "[\s$]") Then 'do something End If

but this doesn't appear to work based on the regex tester here so you may have to go for the ugly hack version or you could combine them into a single regex as in:

var input = "Serial)" var escaped = Regex.Escape (input) var regex = "\s" & escaped & "\s|^" & escaped & "$|\s" & escaped & "$|^" & escaped & "\s" If Regex.IsMatch(Output, regex) Then 'do something End If

Usually when the add-to-cart button does not display it is because your product has no inventory set. Remember that the configurable product needs to be set to in stock and the associated simple products have to have at least one item with non-zero inventory and be set as 'in stock'.

8978532 0 NSView subclass over another NSView subclass?

I'm trying to create an Cocoa-AppleScript Application with some basic functions, and I want to display a background image for the window and then display a color box above it.

I finally figured out how to set the background image via this guide (http://www.mere-mortal-software.com/blog/details.php?d=2007-01-08), but I don't know how to set a color box above it. The basic layout I'm trying to achieve is this:

enter image description here

The window view has a class of ViewBackground which is a subclass of NSView. The ViewBackground.m file looks like this:

-(void)drawRect:(NSRect)rect { NSImage *anImage = [NSImage imageNamed:@"repeat"]; [[NSColor colorWithPatternImage:anImage] set]; NSRectFill([self bounds]); }

Like I said, that works fine. The problem is when I try to put the box with the background color white above it. I thought I would be able to do this by making a new subclass of NSView, ContentBackground. The ContentBackground.m file looks like this:

-(void)drawRect:(NSRect)rect { [[NSColor whiteColor] set]; NSRectFill(rect); }

The hierarchy of my windows looks like this:

enter image description here

Now this sometimes works, but usually produces this result in the debugger:

int main(int argc, char *argv[]) { [[NSBundle mainBundle] loadAppleScriptObjectiveCScripts]; return NSApplicationMain(argc, (const char **)argv); Thread 1: Stopped at breakpoint 1 }

What am I doing wrong and how can I fix this?

Also, the content (buttons, etc..) will go on top of the ContentBackground box.

Reading your comments, i see that it is not a ZF2 error, and probably not even a third party module, so it could be an ElFinder Error. Probably it cannot find some required resources.

Reading some code and some webdites, i think that probably you are just lacking the url option of the viewhelper, so ElFinder can find the backend route he tries to connect to.

With the QuElFinder, the route to the connector is /quelfinder/connector so in your view, the code will be:

echo $this->QuElFinder('elfinder', array( 'width' => "50%", 'height' => '300', 'url' => '/quelfinder/connector' ) );

Also, you should go to QuElFinder/config/module.config.php and check everything under

 'QuConfig'=>array( 'QuElFinder'=>array(

because as you can see in the QuElFinder controller, in the connectorAction() function, it is reading that configuration, and there is a lot of paths.

Dim txtYearPlant As TextBox = DirectCast(DirectCast(sender, DetailsView).FindControl("YearPlant"), TextBox)

Dim txtYearPlant As TextBox = TryCast(view.FindControl("YearPlant"), TextBox) e.Values.Add("YearPlant", txtYearPlant.Text)

So now the value in the PlantYear textbox is saved to the record.

Your replace statement should be a regex string. $ indicates the end of a line in regex, to find a dollar sign you need to escape each one with a \ so your regex should be \$ for each one you want to match.

for the rest, just use CSS

I have an application that run a lot of query using OleDbCommand. Every query is plain SQL text, and the command does not use parameters.

Now, the application should support chinese char and I do not wanto to change every query by adding the N char in front of the string to specify.

I am trying to do something like that, but It does not work:

 OleDbCommand command = new OleDbCommand("?", connect); command.CommandType = CommandType.Text; command.Parameters.AddWithValue("query", qry); OleDbDataAdapter da = new OleDbDataAdapter(command);

where qry is the query to execute without the N char in front of every string.

I really do not wat to change every query, it would be a mess.

Do you have a solution for me?

This is one of those cases where type signatures really help. Stare for a second at the type signature:

(+=) :: (ArrowXml a) => a b XmlTree -> a b XmlTree -> a b XmlTree

First off, ArrowXml is a subclass of Arrow, which describes some sort of machinery taking some input to some output. You can think of it like a big factory with conveyor belts taking things to different machines, and we're building these factory machines and hence factories with functions. Three of the Arrow combinators, for example, are:

(&&&) :: (Arrow a) => a b c -> a b c' -> a b (c, c') |infixr 3| Fanout: send the input to both argument arrows and combine their output. arr :: (Arrow a) => (b -> c) -> a b c Lift a function to an arrow. (.) :: (Category cat) => cat b c -> cat a b -> cat a c morphism composition.

Now look at the lowercase letter (type variable) very closely in:

(+=) :: (ArrowXml a) => a b XmlTree -> a b XmlTree -> a b XmlTree

Clearly we're taking two machines which turn bs into XmlTrees and "merging them together" into one machine which takes a b in and expels an XmlTree. But importantly, this type signature tells us that more or less the only way that this can be implemented is:

arr1 += arr2 = arr f . (arr1 &&& arr2) where f :: (XmlTree, XmlTree) -> XmlTree f = _

This is because of "free theorems"; if you don't know the type of a parameter then we can prove that you can't really do much with it. (It can be a little more complicated because the arrow might have structures which aren't totally encapsulated by arr, like internal counters which are summed together with . which are then set to 0 when using arr. So actually replace arr f with a generic a (XmlTree, XmlTree) XmlTree and you're good to go.)

So we must have parallel execution of the two arrows here. That's what I'm trying to say. Because the combinator (+=) doesn't know what b is, it has no choice but to blithely feed the b to the arrows in parallel and then try to combine their outputs together. So, deep (hasName "bar") does not look at foo.

You can possibly make a mutually recursive solution with deep (hasName "bar") . foo if you really want, but it seems potentially dangerous (i.e. infinite loop), so it may be safer to simply define something like:

a ++= b = a += (b . a)

where the "current" a is "fed" to b to produce the update. To do this you will have to import . from Control.Category as it is not the same as Prelude.. (which does function composition only). This looks like:

import Prelude hiding ((.)) import Control.Category ((.))

First, I'd better do it on SQL Server side :)
But if you don't want or cannot to do it on server side you can use this approach:

It is obvious that you need to store SessionID somewhere you can create a txt file for that or better some settings table in SQL Server or there can be other approaches.

To add columns SessionID and TimeCreated to OLE Destination you can use Derived columns

32709481 0 UIViewController no longer has members topViewController or viewControllers in XCode 7

After updating to XCode 7 and converting my project to the latest Swift 2 syntax, there is one error I cannot seem to fix. I have a segue to a navigation controller and need to pass data to the top view controller in its stack. The following has always worked until now:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { let destinationVC = segue.destinationViewController.viewControllers[0] as! MYViewController // OR let destinationVC = segue.destinationViewController.topViewController as! MYViewController // ... }

But now the compiler gives error:

I do not see how else to access the view controller(s) on the stack. Any ideas? Thanks in advance!

Take a look at the OpenCV doc:

For Canny:

apertureSize: aperture size for the Sobel operator.

And for Sobel:

ksize: size of the extended Sobel kernel; it must be 1, 3, 5, or 7.

So the aperture size in Canny is limited by the Sobel kernel size.

This is verified in the source code :

 if ((aperture_size & 1) == 0 || (aperture_size != -1 && (aperture_size < 3 || aperture_size > 7))) CV_Error(CV_StsBadFlag, "Aperture size should be odd");

So, unless you rewrite yourself some code, there's no way to use Canny with a larger aperture size. You can apply your custom large sobel filter with filter2d, and then code the Canny non maxima suppression.

However, Sobel with mask larger then 3x3 is rarely used in practice.

You can use boolean removeAll(Collection<?> c) method.

Just note that this method modifies the List on which you invoke it. In case you to keep the original List intact then you would have to make a copy of the list first and then the method on the copy.

e.g.

List<Employee> additionalDataInListA = new ArrayList<Employee>(listA); additionalDataInListA.removeAll(listB);

33362460 0 Does every view have its own canvas/bitmap to draw on?

I have a relativelayout with three full screen child views of the same custom view class. I am wondering whether I should be worried about memory. Judging by this answer: Understanding Canvas and Surface concepts

All views get passed the same canvas with underlying bitmap to draw on so that the memory is not tripled. Can anyone confirm? It would make sense, otherwise a full screen textview would be very inefficient.

Bonus: is the purpose of canvas to define a drawable area of a bitmap and translating the view coordinates to bitmap coordinates?

I placed this as an edit in Alex's answer, it did not get reviewed though so I'll post it here, as it is useful information imho.

You can also pass a vector of Points, makes it easier to do something with them afterwards:

std::vector<cv::Point2i> locations; // output, locations of non-zero pixels cv::findNonZero(binaryImage, locations);

One note for the cv::findNonZero function in general: if binaryImage contains zero non-zero elements, it will throw because it tries to allocate '1 x n' memory, where n is cv::countNonZero, and n will obviously be 0 then. I circumvent that by manually calling cv::countNonZero beforehand but I don't really like that solution that much.

JayData does NOT track complex types (like arrays or custom type objects) inner values.. It just tracks the reference to the value.

In case you want to force the update in this case, you have to make a "deep copy" or encapsulate you current object into another one for the reference to change. For example using jQuery:

entity.field = jQuery.extend({}, field);

Nothing really changes for your object values, but it gets encapsulated in jQuery's object and the reference has changed, so JayData thinks it's value has changed and sends the updated values to the server.

It is a workaround, but as my friend said: "Do you really care about how much clients' CPU you use?" :)

It would be better if you sorted the objects you are populating richtextbox1 with instead of trying to split and parse the text of richtextbox1.

Lets say you have a list with students

List<Student> studentList = new List<Student>();

That list could be sorted by using something similar to this:

StringBuilder sb = new StringBuilder(); studentList.OrderByDescending(x=>x.Average) .ToList() .ForEach(x=> sb.Append(String.Format("{0} {1} {2} {3} {4}" + Environment.NewLine,x.Id,x.Name,x.Sname,x.DOB,x.Average))); richTextBox2.Text = sb.ToString();

do/try/catch will catch errors that are thrown by some other method, but it won't catch runtime exceptions, such as you are getting from the forced downcast. For example, if data was invalid JSON then an error will be thrown and caught. In your case it seems the JSON is valid, but it is a dictionary, not an array.

You want something like

setQA = nil do { if let json = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.AllowFragments) as? [AnyObject] { setQA = json print(setQA) } else { self.customAlert("Invalid response from server") } } catch _ { self.customAlert("Error parsing JSON") }

Maybe an idea which might work for you:

To ban a user, create an entry in your database to the user to flag the user as banned with a timestamp NOW + X

{ "users" : { "bad_user" : { "banned" : { "until" : 123456 // timestamp NOW + X } } } }

Now whenever the user logs in afterwards, you check wether the user is banned and immediately try to delete that entries. If it fails, penalty time is still running. If it succeeds, well then the user can use your app :)

The trick is to use firebase rules to restrict possible changes.

something like:

{ "rules" : { "users" : { "$uid" : { // ... "banned" : { .write : "(!newData && now < data.child('until').val() )" ....

Please note - these are not working rules, but should help to figure it out.

35160200 0 Express & Passport with multiple subdomains

I'm merging two little apps into one, that is supposed to be accessed via two subdomains. To do so I'm using the module "express-subdomain". I'm trying to use Passport so when a user logs in in the first app, he is logged in in both apps. However using req.isAuthenticated() I can indeed login in the "first" app, but then I'm not in the "second" one.

I'm searching for any solution to have a passport authentification in the first subdomain and being logged in in the second one, including keeping two disctinct apps if needed.

Assuming that passport is correctly configured for a local strategy, as well as the routers and the rest of the app. Here is what it looks like :

app.js

// <- requires etc var passport = require('./configurePassport.js')(require('passport')); var app = express(); app.use(cookieParser()); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({extended: true})); app.use(expressSession({ secret: 'bestSecretEver', resave: false, saveUninitialized: false })); app.use(passport.initialize()); app.use(passport.session()); // and others var firstRouter = express.Router(); firstRouter.use('/public', express.static(__dirname + '/first/public')); firstRouter.use(favicon(__dirname + '/first/public/favicon.ico')); // <- setting first router's GET, POST etc app.use(subdomain('sub1', firstRouter)); // for sub1.example.com var secondRouter = express.Router(); secondRouter.use('/public', express.static(__dirname + '/second/public')); secondRouter.use(favicon(__dirname + '/second/public/favicon.ico')); // <- setting second router's GET, POST etc app.use(subdomain('sub2', secondRouter)); // for sub2.example.com

Any idea ?

You can use a form inside your application. And, ask users to fill that form. The forms needs to be connected to an database server. You may use 000webhost.com (free) to create your database. Just populate the table in database from the user response. For this follow the following procedure:
1. Create a online database (000webhost.com)
2. Write php code to insert data into the database form and save that php on the file manager on server.
3. From android create a async task to execute that php.
4. Pass your parameter or user response as request attributes while executing the php.
5. php will save user's response on your server.
Now you can access that database from anywhere.

Note: This may require an internet connection in application.

3379561 0 Integrate an E-Mail server into ASP.NET

I've a general design question:

I have a mailserver, written in C#.
Then I have a web forum software, written in for ASP.NET in C#.

Now I'd like to integrate the mailserver into the ASP.NET forum application. For example, I'd like to make it possible that one can create a mailinglist from the forum, and give users the oportunity to add oneselfs to the mailinglist members in the forum, and then add the new list-members to the respective mailinglist on the server.

Since the server is a separate console/winforms/service application, I first thought I'd best use .NET remoting for this.

But my second thought was, that some users might host their forum on a host where
(a) they don't have a virtual machine where they can do what they want
(b) the admin of the host might not want to install an additional mailserver or charge extra for this
(c) the user might have a service plan that only permits to add a web-application, not external programs (very likely)

Now, I wanted to ask:
Is it possible to fully integrate a mailserver into an ASP.NET application somehow ? (I have the full source of the server + ASP.NET application)

Well, it probably won't be a page or a ashx handler, but something like a http module ? Or what's the general way to integrate TCP/IP applications into asp.net ? (Of course I'm assuming the respecive ports are available/forwarded - and I'll make it possible to also run it with the e-mail server as external application)

I finally decided to switch to AVPlayer

setCurrentPlayback is

int32_t timeScale = playerView.currentItem.asset.duration.timescale; CMTime time = CMTimeMakeWithSeconds(value, timeScale); [playerView seekToTime:time toleranceBefore:kCMTimeZero toleranceAfter:kCMTimeZero];

Duration is

CMTime duration = playerView.currentItem.asset.duration; float seconds = CMTimeGetSeconds(duration);

Same pause and Play functions.

There is an equation given here (the last one).

By looping over all the x and y coordinates, and checking that the output of this equation is less than zero, you can determine which points are 'inside' and colour them appropraitely.

37776272 0 Why invariant generic type parameterized with subclass of upper bounds fails to conform?

Given:

class Invar[T] trait ExtendsAnyref extends AnyRef def f(a: Invar[ExtendsAnyref]) = {}

The following is erroneous

scala> val x: Function1[Invar[_ <: AnyRef], Unit] = f <console>:13: error: type mismatch; found : Invar[ExtendsAnyref] => Unit required: Invar[_ <: AnyRef] => Unit val x: Function1[Invar[_ <: AnyRef], Unit] = f ^

Why?

I understand that in Scala, generic types have by default nonvariant subtyping. Thus, in the context of this example, instances of Invar with different type parameters would never be in a subtype relationship with each other. So an Invar[ExtendsAnyref] would not be usable as a Invar[AnyRef].

But I am confused about the meaning of _ <: AnyRef which I understood to mean "some type below AnyRef in the type hierarchy." ExtendsAnyref is some type below AnyRef in the type hierarchy, so I would expect Invar[ExtendsAnyref] to conform to Invar[_ <: AnyRef].

I understand that function objects are contravariant in their input-parameter types, but since I use Invar[_ <: AnyRef] rather than Invar[AnyRef] I understood, apparently incorrectly, the use of the upper bounds would have the meaning "Invar parameterized with Anyref or any extension thereof."

What am I missing?

To allow nice zooming you should add this line to the two you show:

chart1.ChartAreas["ChartArea1"].AxisX.ScaleView.Zoomable = true;

Here is a function to calculate an average of the visible points' 1st YValues:

private void chart1_AxisViewChanged(object sender, ViewEventArgs e) { // for a test the result is shown in the Form's title Text = "AVG:" + GetAverage(chart1, chart1.Series[0], e); } double GetAverage(Chart chart, Series series, ViewEventArgs e) { ChartArea CA = e.ChartArea; // short.. Series S = series; // references DataPoint pt0 = S.Points.Select(x => x) .Where(x => x.XValue >= CA.AxisX.ScaleView.ViewMinimum) .DefaultIfEmpty(S.Points.First()).First(); DataPoint pt1 = S.Points.Select(x => x) .Where(x => x.XValue <= CA.AxisX.ScaleView.ViewMaximum) .DefaultIfEmpty(S.Points.Last()).Last(); double sum = 0; for (int i = S.Points.IndexOf(pt0); i < S.Points.IndexOf(pt1); i++) sum += S.Points[i].YValues[0]; return sum / (S.Points.IndexOf(pt1) - S.Points.IndexOf(pt0) + 1); }

Note that the ViewEventArgs parameter is providing the values of the position and size of the View, but these are just the XValues of the datapoints and not their indices; so we need to search the Points from the left for the 1st and from right for the last point.

Update Sometimes the zooming runs into a special problem: When the data are more finely grained than the default CursorX.IntervalType it just won't let you zoom. In such a case you simply have to adapt to the scale of your data, e.g. like this: CA.CursorX.IntervalType = DateTimeIntervalType.Milliseconds;

26761856 0 Rounding error on percent of total and back

A and B are integers.

Is it certain, with all the complexities of rounding errors in JavaScript, that:

(A/(A+B))*(A+B) === A

This is to say that if the user enters 10, and 20 for A and B respectively, can I store the summed total (30) with A = .33333333 and B = .66666666 and later multiply the sum by these decimals to get back to the value of 10 (with no rounding error)?

25184607 1 Sort a dictionary of arrays in python with a tuple as the key

I a dictionary with a string tuple as the key and an array as the value:

some_dict = {} some_dict[(A,A)] = [1234, 123] some_dict[(A,B)] = [1235, 13] some_dict[(A,C)] = [12, 12] some_dict[(B,B)] = [12621, 1] ...

I am writing this to a csv file:

for k,v in some_dict.iteritems(): outf.write(k[0]+","+k[1]+","+str(v[0])+","str(v[1])+"\n")

output:

A,A,1234,123 A,B,1235,13 A,C,12,12 B,B,12621,1

I'd like to sort it based on the first number "column" before writing to a file (or after and just rewrite?) so the output should be like:

B,B,12621,1 A,B,1235,13 A,A,1234,123 A,C,12,12 ^ Sorted on this 'column'

How do I do this? The file is very large, so doing it before writing would be better I think.

Focus Handling

Focus movement is based on an algorithm which finds the nearest neighbor in a given direction. In rare cases, the default algorithm may not match the intended behavior of the developer.

Change default behaviour of directional navigation by using following XML attributes:

android:nextFocusDown="@+id/.." android:nextFocusLeft="@+id/.." android:nextFocusRight="@+id/.." android:nextFocusUp="@+id/.."

Besides directional navigation you can use tab navigation. For this you need to use

android:nextFocusForward="@+id/.."

To get a particular view to take focus, call

view.requestFocus()

To listen to certain changing focus events use a View.OnFocusChangeListener

Keyboard button

You can use android:imeOptions for handling that extra button on your keyboard.

Additional features you can enable in an IME associated with an editor to improve the integration with your application. The constants here correspond to those defined by imeOptions.

The constants of imeOptions includes a variety of actions and flags, see the link above for their values.

Value example

ActionNext :

the action key performs a "next" operation, taking the user to the next field that will accept text.

ActionDone :

the action key performs a "done" operation, typically meaning there is nothing more to input and the IME will be closed.

Code example:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" > <EditText android:id="@+id/editText1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:layout_marginLeft="32dp" android:layout_marginTop="16dp" android:imeOptions="actionNext" android:singleLine="true" android:ems="10" > <requestFocus /> </EditText> <EditText android:id="@+id/editText2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignLeft="@+id/editText1" android:layout_below="@+id/editText1" android:layout_marginTop="24dp" android:imeOptions="actionDone" android:singleLine="true" android:ems="10" /> </RelativeLayout>

If you want to listen to imeoptions events use a TextView.OnEditorActionListener.

editText.setOnEditorActionListener(new TextView.OnEditorActionListener() { @Override public boolean onEditorAction(TextView v, int actionId, KeyEvent event) { if (actionId == EditorInfo.IME_ACTION_SEARCH) { performSearch(); return true; } return false; } });

Instead of doing this: public static final TitleType MR = new TitleType(1, "Mr");

You should use the EntityManager to fetch that Object. Otherwhise Hibernate will notice, that this Object (with id 1) is already stored, but since you did not load it, the entity manager does not have it inside its own collection -> that's a detached entity.

So, you should do:

TitleType MR = em.find(TitleType.class, 1); Person p = new Person(...); p.setTitleType(MR); em.merge(p);

Your input text is full of a mix of word and non-word characters, so the only way to determine a word boundary is to look behind and ahead for spaces:

re.findall(ur'(?<![^ ])വി[^ ]+ണ്?(?![^ ])', inputtext, flags=re.UNICODE)

where inputtext is a Unicode value. The (?<!...) and (?!...) are negative lookbehind and lookahead assertions; the match locations in the text that are not preceded or followed by a non-space character, respectively.

Within your boundary text, we match non-spaces as well.

This matches your expected input:

>>> print re.findall(ur'(?<![^ ])വി[^ ]+ണ്?(?![^ ])', inputtext, flags=re.UNICODE)[0] വിചാരണ

Actually an array is a fixed pointer to the first element in the array (I think this is known as an L-value). This means your assignments at the end for the tempState, currState and nextState cannot work (as you have discovered).

After declaring space for the 2 2d-arrays, you could then declare pointers to the 2d arrays which you might be able to work in a reasonable way. To use the pointers for indexing into the 2-d array, the compiler would need to be aware of the size of the last dimension(s) of the array.

RDD is Apache Spark's abstraction for a Distributed Resilient Dataset

To create an RDD you'll need an instance of SparkContext, which can be thought of as a "connection" or "handle" to a cluster running Apache Spark.

Assuming:

You have an instantiated SparkContext
You want to treat your input as a "flat" sequence of (Double, Double) values, ignoring the way these are currently "split" into sub-sequences in Seq[Seq[(Double, Double)]]

You can create an RDD as follows:

val sc: SparkContext = ??? val output: Seq[Seq[(Double, Double)]] = ??? val rdd: RDD[(Double, Double)] = sc.parallelize(output.flatten)

40985875 0 Getters, Setters and Constructors in Java - Making a car and stocking it

I'm trying to create a class in Java using BlueJ. My class is named Automobile. My goal is to be able to use my Constructor method to create cars with the variables: year, color, brand, number of doors, number of kilometers, if it's automatic (boolean), if it's sold (boolean), a description, and an identification number. All the variables have a set default value, a minimum and a maximum accepted value.

I have to use getVariablename and setVariablename for my methods. My color and brand variables are int, and I made methods to retrieve their String counterparts in a table in my class.

My issue is I don't understand the principle of setting my variable in one method and getting it in another (while making sure it's an accepted value). Also, once I have my Setter and Getter method, what do I have to write down in the creation of my Constructor method?

Up to now, I have this :

public class Automobile { private static final String[] COLORS = { "Other", "Noir", "Blanc", "Bleu Nuit", "Bleu Clair", "Vert Pomme", "Vert Bouteille", "Taupe", "Argent", "Sable"}; private static final String[] BRANDS = { "Autre", "Mazda", "Toyota", "Ford", "GM", "Hyunday", "BMW", "SAAB", "Honda"}; public static final int COLOR_DEF = 8; public static final int COLOR_MIN = 0; public static final int COLOR_MAX = COULEURS.length - 1; public static final int BRAND_DEF = 4; public static final int BRAND_MIN = 0; public static final int BRAND_MAX = MARQUES.length - 1; public static final double KILO_DEFAULT = 55000; public static final double KILO_MIN = 15000; public static final double KILO_MAX = 140000; public static final int TWO_DOORS = 2; public static final int FOUR_DOORS = 4; public static final int DOORS_DEFAULT = FOUR_DOORS; public static final boolean AUTO_DEF = true; public static final int YEAR_MIN = 1997; public static final int YEAR_MAX = 2016; public static final int YEAR_DEFAUT = 2007; public static final String COMM_DEFAUT = ""; public static String color (int cou) { String chainecolor = ""; if (cou >= COLOR_MIN && cou <= COLOR_MAX) { chainecolor = COLORS[cou]; } return chainecolor; } //This method is to return the String value of a color from its int value using the COLORS table. If invalid it returns an empty chain. public static String brand (int br) { String chainebrand = ""; if (ma >= BRAND_MIN && ma <= BRAND_MAX) { chainebrand = BRANDS[br]; } return chainebrand; } //same thing for the brand public Automobile (int brand, int year, int color, boolean automatic, double kilometers,int nbrDoors, String description, boolean sold){ //To be completed } //here i'm supposed to create getters that return int values for everything but automatic, sold and description public void setYear ( int year ) { if (year >= YEAR_MIN && YEAR <= YEAR_MAX) { year = year; } } // supposed to be the setter for my year, as long as it's within the accepted values public void setMarque (int brand){ if (brand >= BRAND_MIN && brand <= BRAND_MAX) { brand = brand; } } //same, for the brand public void setColor (int color) { if (color >= COLOR_MIN && color <= COLOR_MAX){ color = color; } }// same for the color public void setNbrDoors (int p) { if (p == TWO_DOORS || p == FOUR_DOORS){ p = p; } } // same for the door. I am forced to use (int p) as the variable for this method, which confuses me as to how I will refer to it from nbrDoors up in the Automobile constructor method } // Automobile

So my difficulties lie in:

Are the examples of setters that I made valid for this purpose? I do not understand the need for p = p, or color = color...
How do I create a getter method that will be able to go pick up the Variable p from setNbrDoors, return its value and have it be used for nbrDoors in the Automobile constructor?
What am I supposed to write in the Constructor method, such as it will be able to get its values from the getters?

This is all because the second part is I will have to create a little code to ask the user to input all the values for variables, then create a table to stock the Cars the user creates.

P.S.: the work is originally in french, so I translated the variable and method names best I could for your better understanding. Also, the variable names, methods, etc are all imposed, I am FORCED to make the class this way exactly.

EDIT: As such, the use of static for brand and color conversion are also imposed. Those 2 methods are solely for returning a String of character from an int value. they are not used in the Constructor. Finally, the exceptions will be handled in the second part of the work using a separate validation loop. The Automobile class is really used solely to handle the creation of the "car" object.

While you can change the VM sizes now as part of an in-place update, you should expect some instance downtime. The Windows Azure fabric controller will walk the upgrade domains, taking 1 upgrade domain down to change the VM sizes, and then moving on to the next. If you have 2 instances, you shouldn't have noticed an entire outage (just 1 machine going down at a time).

Neo4j does not support storing another object as a nested property. Neo4j-OGM only supports

any primitive, boxed primitive or String or arrays thereof, essentially anything that naturally fits into a Neo4j node property.

If you want to work around that, you may need to create a custom type convertor. For example,

import org.neo4j.ogm.typeconversion.AttributeConverter class XYZ{ XYZ(Integer x, String y) { this.x = x this.y = y } Integer x String y } public class XYZConverter implements AttributeConverter<XYZ, String> { @Override public String toGraphProperty(XYZ value) { return value.x.toString() + "!@#" + value.y } @Override public XYZ toEntityAttribute(String value) { String[] split = value.split("!@#") return new XYZ(Integer.valueOf(split[0]), split[1]) } }

You can then annotate the @NodeEntity with a @Convert like this

@NodeEntity class Node { @GraphId Long id; @Property String name @Convert(value = XYZConverter.class) XYZ xyz }

On the flip side, its not a good practice to do this, since ideally you should link Node and XYZ with a 'hasA' relationship. Neo4j has been designed to optimally handle such kind of relationships, so it would be best to play with to strengths of neo4j

This suggests you're trying to access your resources too early, for example when initializing your member variables. Only call getResources() in onCreate() or later in activity lifecycle.

After fixing that you'll find that mWebView is null as suggested by others. You'll need to setContentView() first before calling findViewById() to find components in your content view hierarchy.

You cannot use document.write() once the document is loaded. Doing so will cause the entire document to be cleared and a new one started. If you want to add text to a document that has already been loaded, then you can use the appropriate jQuery methods to modify existing elements or add new ones.

To help you with the exact code, we would need to see your HTML and a more complete description of exactly what you're trying to add to it.

As some examples, one can add objects to an element with the .append() jquery method or using the .html() method.

i was struggling a while back with the same problem. i was following ryan bates screencast on delayed_job and got the same error 'uninitialized constant Delayed::Job'. In the screencast ryan creates a file called mailing_job.rb(located under lib folder) with the delayed_job perform method inside, which allows you to use the enqueue method. After doing some research i found that rails 3 does not automatically load the lib folder files into your app.(not entirely sure)

Try this
In your controller where you use this:

"Delayed::Job.enqueue do_it(), 0, 1.minutes.from_now.getutc"

Try to require the file like this.

require 'mailing_job' class AssetsController < ApplicationController def some_method Delayed::Job.enqueue do_it(), 0, 1.minutes.from_now.getutc end end

Now I want to create my own document set that will live outsite of /software/packages/solr-4.3.1/ but still use the instance of solr that lives in /software/packages/solr-4.3.1/. I copied over the example directory to /path/to/mydocs. I tried to go through the tutorial again from the new location. No dice. How do I tell solr where my document collection is?

16225047 0 How to check if button is clicked while text input has focus using jQuery

I'm relatively new to code and have been building a little project called http://keyboardcalculator.com/ to improve my jQuery.

I'm trying to add some more features to improve some things - and I've coded them! - but I want to add a button at the bottom of the page that displays a div to tell people what they are.

I don't want to tarnish the user flow when the button is clicked - and a big part of that for me is that I don't want the user to have to click back into one of the text-input boxes to keep doing calculations.

I want the focus to go back onto the last text-input that the user had focus on. This is my attempt to get it working on the #ansinput text-input field (the big one with the answer in):

if ($('#ansinput').is(':focus')) { $('#more-commands-button').click(function() { alert('hello') }); }

But I'm not getting my alert.

Any help as where to go from here would be fantastic!

Thank you very much StackOverflow!

34508804 1 Count number of foreign keys in Django

I've read the documentation and all the other answers on here but I can't seem to get my head around it.

I need to count the number of foreign keys in an other table connected by a foreign key to a row from a queryset.

class PartReference(models.Model): name = models.CharField(max_length=10) code = models.IntegerField() class Part(models.Model): code = models.ForeignKey(PartReference) serial_number = models.IntegerField()

I'll do something like:

results = PartReference.objects.all()

But I want a variable containing the count of the number of parts like any other field, something like:

results[0].count

to ultimately do something like:

print(results[0].name, results[0].code, results[0].count)

I can't wrap my head around the Django documentation- There is a some stuff going on with entry_set in the example, but doesn't explain where entry came from or how it was defined.

32212331 0 LINQ query with many tables, left outer joins, and where clause

I need to translate this SQL query into LINQ in c#. I would appreciate any help or guidance you can give. (I'm using entity framework 6).

SELECT f.FacId ,sli.SitLocIntId ,ei.EnvIntId ,p.PhoId FROM Fac AS f join SitLocInt AS sli on f.FacId = sli.FacId join EnvInt AS ei on sli.EnvIntId = ei.EnvIntId join EnvIntTyp AS eit on ei.EnvIntTypId = eit.EnvIntTypId left outer join Aff AS a on ei.EnvIntId = a.EnvIntId left outer join AffCon AS ac on a.AffId = ac.AffId left outer join Con AS c on ac.ConId = c.ConId left outer join Pho AS p on c.ConId = p.ConId WHERE EnvIntTyp = 'Fleet'

I've been looking at group join syntax, but with so many tables, a lot of left outer joins and a where clause I haven't made much headway. So far I have

 var testQuery = from f in _CEMDbContext.setFac join sli in _CEMDbContext.setSitLocInt on f.FacId equals sli.FacId join ei in _CEMDbContext.setEnvInt on sli.EnvIntId equals ei.EnvIntId join eit in _CEMDbContext.setEnvIntTyp on ei.EnvIntTypId equals eit.EnvIntTypId into eiGroup from item in eiGroup.DefaultIfEmpty().Where(e => e.EnvIntTyp == "Fleet") select new BusinessParticipant { fac = f, sitLocInt = sli, envInt = ei, // pho = p, // not working... Phone number from table Pho. }; var TestList = testQuery.ToList();

Getting the EnvIntTyp "Fleet" and all its associated data including Fac, SitLocInt, and EnvInt is working. But I run into trouble when I try to get the phone number from table Pho which may or may not exist. Is there a nice way to chain together all the left outer joins? Thanks for advice or direction!

Edit I don't just need the Ids as I wrote in the SQL query, but the whole object. Plus, I should mention that EnvIntTyp is a member of the table of the same name.

Edit 2 Here are (parts of) the relevant entities. Fac is an abbreviation for Facility. SitLocInt is an abbreviation for SiteLocationInterest. EnvInt stands for EnvironmentalInterest. Aff is for Affiliation. Con is for Contact. Pho is for Phone.

public partial class Facility { public Facility() { this.SiteLocationInterests = new List<SiteLocationInterest>(); } public int FacilityId { get; set; } public string FacilityIdentifier { get; set; } public string FacilityName { get; set; } public int SiteTypeId { get; set; } public string FacilityDescription { get; set; } [ForeignKey("GeographicFeature")] public Nullable<int> GeographicFeatureId { get; set; } [Display(Name = "resAddress", ResourceType = typeof(CEMResource))] public string AddressLine1 { get; set; } [Display(Name = "resAddressLine2", ResourceType = typeof(CEMResource))] public string AddressLine2 { get; set; } public string City { get; set; } [Display(Name = "resState", ResourceType = typeof(CEMResource))] public string StateCode { get; set; } [Display(Name = "resZip", ResourceType = typeof(CEMResource))] public string AddressPostalCode { get; set; } public string CountyName { get; set; } public virtual GeographicFeature GeographicFeature { get; set; } public virtual ICollection<SiteLocationInterest> SiteLocationInterests { get; set; } } public partial class SiteLocationInterest { public int SiteLocationInterestId { get; set; } [ForeignKey("Facility")] public Nullable<int> FacilityId { get; set; } [ForeignKey("EnvironmentalInterest")] public Nullable<int> EnvironmentalInterestId { get; set; } public Nullable<int> EventId { get; set; } [ForeignKey("GeographicFeature")] public Nullable<int> GeographicFeatureId { get; set; } public System.DateTime CreateDate { get; set; } public string CreateBy { get; set; } public System.DateTime LastUpdateDate { get; set; } public string LastUpdateBy { get; set; } public virtual EnvironmentalInterest EnvironmentalInterest { get; set; } public virtual Facility Facility { get; set; } public virtual GeographicFeature GeographicFeature { get; set; } } public partial class EnvironmentalInterest { public EnvironmentalInterest() { this.Affiliations = new List<Affiliation>(); this.SiteLocationInterests = new List<SiteLocationInterest>(); } public int EnvironmentalInterestId { get; set; } public string EnvironmentalInterestIdentifier { get; set; } public string EnvironmentalInterestFacilityIdentifier { get; set; } public string FacilityIdentifier { get; set; } public string EnvironmentalInterestName { get; set; } [ForeignKey("EnvironmentalInterestType")] public int EnvironmentalInterestTypeId { get; set; } public Nullable<int> EnvironmentalInterestSubTypeId { get; set; } public string EnvironmentalInterestDescription { get; set; } public virtual ICollection<Affiliation> Affiliations { get; set; } public virtual EnvironmentalInterestType EnvironmentalInterestType { get; set; } public virtual ICollection<SiteLocationInterest> SiteLocationInterests { get; set; } } public partial class Affiliation { public Affiliation() { this.AffiliationContacts = new List<AffiliationContact>(); } public int AffiliationId { get; set; } public string AffiliationIdentifier { get; set; } public string AffiliationName { get; set; } [ForeignKey("Entity")] public Nullable<int> EntityId { get; set; } [ForeignKey("EnvironmentalInterest")] public Nullable<int> EnvironmentalInterestId { get; set; } public int AffiliationTypeId { get; set; } public int StatusTypeId { get; set; } public virtual EnvironmentalInterest EnvironmentalInterest { get; set; } public virtual ICollection<AffiliationContact> AffiliationContacts { get; set; } } public partial class AffiliationContact { public int AffiliationContactId { get; set; } public int AffiliationId { get; set; } public int ContactId { get; set; } public virtual Affiliation Affiliation { get; set; } public virtual Contact Contact { get; set; } } public partial class Contact { public Contact() { this.AffiliationContacts = new List<AffiliationContact>(); this.Phones = new List<Phone>(); } public int ContactId { get; set; } public string ContactIdentifier { get; set; } public int EntityId { get; set; } public Nullable<int> MailAddressId { get; set; } public int ContactTypeId { get; set; } public string FirstName { get; set; } public string LastName { get; set; } public string EmailAddress { get; set; } public virtual ICollection<AffiliationContact> AffiliationContacts { get; set; } public virtual Entity Entity { get; set; } public virtual ICollection<Phone> Phones { get; set; } } public partial class Phone { public int PhoneId { get; set; } public int ContactId { get; set; } public int ContactTypeId { get; set; } public string PhoneNumber { get; set; } public string PhoneExtensionNumber { get; set; } public virtual Contact Contact { get; set; } public virtual ContactType ContactType { get; set; } }

if you are fine adding variables to the global scope then:

var firstname; var secondname; var checkName = function() { if(firstname != null && secondname != null){ console.log(firstname); console.log(secondname); } } $('#first_name').live("change", function(){ firstname=$(this).val(); checkName(); }); $('#second_name').live("change", function(){ secondname=$(this).val(); checkName(); });

C compiles down to machine code and doesn't require any runtime support for the language itself. This means that it's possible to write code that can run before things like filesystems, virtual memory, processes, and anything else but registers and RAM exist.

2359493 0 Starting multiple gui (WinForms) threads so they can work separetly from one main gui in C#?

I've one MainForm window and from that user can press 3 buttons. Each of the button starts new Form in which user can do anything he likes (like time consuming database calls etc). So i decided to put each of the forms in it's own threads:

 private Thread subThreadForRaportyKlienta; private Thread subThreadForGeneratorPrzelewow; private Thread subThreadForRaporty; private void pokazOplatyGlobalne() { ZarzadzajOplatamiGlobalneDzp varGui = new ZarzadzajOplatamiGlobalneDzp(); varGui.ShowDialog(); } private void pokazRaportyKlienta() { RaportyDzpKlient varGui = new RaportyDzpKlient(); varGui.ShowDialog(); } private void pokazRaportyWewnetrzne() { RaportyDzp varGui = new RaportyDzp(); varGui.ShowDialog(); } private void pokazGeneratorPrzelewow() { ZarzadzajPrzelewamiDzp varGui = new ZarzadzajPrzelewamiDzp(); varGui.ShowDialog(); } private void toolStripMenuGeneratorPrzelewow_Click(object sender, EventArgs e) { if (subThreadForGeneratorPrzelewow == null || subThreadForGeneratorPrzelewow.IsAlive == false) { subThreadForGeneratorPrzelewow = new Thread(pokazGeneratorPrzelewow); subThreadForGeneratorPrzelewow.Start(); } else { } } private void toolStripMenuGeneratorRaportow_Click(object sender, EventArgs e) { if (subThreadForRaporty == null || subThreadForRaporty.IsAlive == false) { subThreadForRaporty = new Thread(pokazRaportyWewnetrzne); subThreadForRaporty.Start(); } else { } } private void toolStripMenuGeneratorRaportowDlaKlienta_Click(object sender, EventArgs e) { if (subThreadForRaportyKlienta == null || subThreadForRaportyKlienta.IsAlive == false) { subThreadForRaportyKlienta = new Thread(pokazRaportyKlienta); subThreadForRaportyKlienta.Start(); } else { } }

I've got couple of questions and i hope someone could explain them:

When i use Show() instead of ShowDialog() the windows just blink for a second and never shows. What's the actual difference between those two and why it happens?
When i use ShowDialog everything seems normal but i noticed not everything gets filled properly in one of the gui's (one listView stays blank even thou there are 3 simple add items in Form_Load(). I noticed this only in one GUI even thou on first sight everything works fine in two other gui's and i can execute multiple tasks inside those Forms updating those forms in background too (from inside the forms methods). Why would this one be diffrent?
What would be proper way of doing this? Tasks performed in each of those Forms can be time consuming and i would like to give user possibility to jump between those 4 windows without problem so he can execute what he likes.

You can allocate the array as a contiguous bloc like this. Suppose you want ints:

int (*arr)[secondCount] = malloc( sizeof(int[firstCount][secondCount]) );

You could hide this behind a macro which takes the typename as a macro argument, although the code is simple enough that that is not really necessary.

34595020 0 Symfony 2: How to dynamically adjust configuration parameters

For my AppBundle (THE APPLICATION ITSELF, NOT A REUSABLE BUNDLE) I have a configuration parameter that is a path. I'd like to be sure the path ends with a /.

In this moment I have a method in the entity that uses this path (yes is an entity and not a controller) adjust the configuration parameter with a code like this:

public function buildLogoFolder($folder) { // Replace the placeholder with the current Entity's URL $folder = str_replace('{entity_domain}', $this->getDomain()->getCanonical(), $folder); $folder = rtrim(ltrim($folder, '/'), '/') . '/'; return $folder; }

As the $folder parameter comes from the config.yml file I'd like to move outside of the entity this adjustment.

I think I should use a solution similar to the one suggested here, that is the use of the DependencyInjection component.

I think the process is very similar to the loading of a configuration file for a new bundle as explained in the Symfony's documentation but I'm not sure on how to proceed.

Is there someone who can put me on the right way?

I'd like to automate the process. I want read the folder configuration parameter value and then adjust it with the method I wrote above.

I want to be sure that the folder parameter configured ever ends with a trailing slash, also if the developer didn't write it in the configuration.

So, If the developer write something like path/to/folder the resulting configuration parameter is automatically adjusted to path/to/folder/.

If you select only HEAD, than any changes in any revisions prior to HEAD will not be included in the merge. You either need to select ALL the revisions in the branch whose changes are not yet included in your branch, or leave the range specifier empty to allow SVN to figure out which revisions to merge.

Edited to add example

When you do a "range of revisions" merge, you are picking individual CHANGES to cherry-pick over into your merge destination. If you say "merge HEAD" you are not saying "merge all changes up through HEAD", you are saying "merge only the specific change that happened in the very last revision on that branch". Consider a trunk with revision 122; a MayBranch with revisions 123, 124, and 125; and an AugustBranch with revisions 126 and 127. Both branches were copied from trunk revision 122.

You want all three changes on the MayBranch–123, 124, and 125–to be merged into your AugustBranch. If you select all three revisions, or leave the revision specifier empty, this will happen. The merge will use revision 122 on trunk as the BASE, with 125 on MayBranch as source revision, and 127 on AugustBranch as destination revision.

If instead you select HEAD as the revision to merge, SVN will use revision 124 on MayBranch as the BASE, with 125 as the source revision and 127 as destination as before. Since BASE is now the place where revision 125's changes were started from, you only get the changes that specifically happened in revision 125.

The final result is as if you had exported only revision 125 on MayBranch as a diff, and then applied that diff to the AugustBranch. Except this is done with merge tracking information included so that SVN knows how to get the whole branch automatically later if you like.

Most of the answers here I don't think are really going to wow anyone, especially a tech crowd. They might be surprised that Perl can do it, but they aren't going to be surprised that you can do the task. However, even if they aren't surprised that you can do it, they might be surprised how fast, or with how little code, you can do it.

If you're looking for things to show them that will wow them, you have to figure out what they think is hard in their jobs and see if Perl could make it really easy. I find that people tend not to care if a language can do something they don't already have an interest in. That being said, impressing anyone with Perl is the same as impressing anyone in any other subject of field: you have to know them and what they will be impressed by. You have to know your audience.

Perl doesn't really have any special features that allow it to do any one thing that some other language can also do. However, Perl combines a lot of features that you usually don't find in the same programming language.

Most of the things that I'm impressed by have almost nothing to do with the language:

There's a single codebase that runs on a couple hundred different platforms, despite differences in architecture.
Perl's CPAN is still unrivaled among other languages (which is really sad because it's so easy to do the same thing for other languages).
The testing culture has really raised the bar in Perl programming, and there's a lot of work that teases out platform dependencies, cross-module issues, and so on without the original developer having to do much.

 while(token != NULL){ printf("%s\n", token); token = strtok(NULL, space); }

The while loop will fail when the token is NULL. At this time you are trying to print this pointer using your second printf() in the while loop which will lead to undefined behavior.

Get rid of your second printf()

7387938 0 Modifying an existing MVVM infrastructure by adding View State feature

I'm going to introduce View State feature in the existing MVVM WPF Application. The objective is to be able to Save and Load (restore) particular state of a control.

The question is more about design and best solution from system flexibility/maintability perspectives.

Current infrastructure:

public abstract class ViewModelBase { protected ViewModelBase(...) { } } // and few more very the same ViewModel classes for different control types public sealed class GridViewModel : ViewModelBase { protected GridViewModel(...) : base(...) { } }

I'm introduced IViewState interface so each specific ViewModel could provide own implementation like GridViewState class and going to put it in ViewModel infrastructure in following way: (Idea is to pass type of ViewState as generic parameter)

public abstract class ViewModelBase<TViewState> where TViewState : class, IViewState { protected ViewModelBase(...) { } public TViewState ViewState { ... } }

Is it a good idea to attach View State feature to ViewModel?
Is it a good solution to introduce tied relation between specific ViewModel typa and ViewState through the generic Type parameter like class GridViewModel<GridViewState>?
Where and why better to define such methods like LoadState() / SaveState(), IViewState itself or ViewModelBase?
Are there another design solutions?

well, if you are reffering to the highlighted button in the second image, it doesn't have active class, it's a non-active class. by setting all buttons as active initially,on first click it simply becomes inactive. You might want to think about what you are doing.

Update if you want to change the grey color you can do so by adding another class and toggling it as follows:

.select{ background-color:white !important; } $("div").children().click(function () { $(this).toggleClass("select"); });

I have created a simple website app wrapped via Cordova and Crosswalk and it displays a black screen when reopening

I used Intel XDK.

When I open the app, it displays great. I can select button links to websites and even use the phone back button to go back to the main page.

However when I close and reopen the app - it displays a black screen with a thin blue line on the left side. I have to close it thru the phone soft key app close button.

I added this below but that does not seem to help either

function onLoad() { document.addEventListener("deviceready", onDeviceReady, false); } document.addEventListener("backbutton", onBackKeyDown, false); function onBackKeyDown() { // Handle the back button navigator.app.exitApp(); }

6232305 0 Cant get a control from a TabControl DataTemplate

I've been googling this for the last 2 days and cant get anywhere, I just cant do anything to any control in a datatemplate of a tabcontrol.

First off, the code:

private void Window_Loaded(object sender, RoutedEventArgs e) { tabControl1.ItemsSource = new string[] { "TabA", "TabB", "TabC" }; } private void tabControl1_SelectionChanged(object sender, SelectionChangedEventArgs e) { ContentPresenter cp = tabControl1.Template.FindName("PART_SelectedContentHost", tabControl1) as ContentPresenter; DataTemplate dt = tabControl1.ContentTemplate; Grid g = tabControl1.ContentTemplate.FindName("myGrid", cp) as Grid; g.Background = new SolidColorBrush(Colors.Red); }

xaml

<Window x:Class="tabTest.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded"> <Grid> <TabControl IsSynchronizedWithCurrentItem="True" Height="140" Name="tabControl1" Width="230" SelectionChanged="tabControl1_SelectionChanged"> <TabControl.ContentTemplate> <DataTemplate> <Grid x:Name="myGrid"> </Grid> </DataTemplate> </TabControl.ContentTemplate> </TabControl> </Grid>

In short this line:

Grid g = tabControl1.ContentTemplate.FindName("myGrid", cp) as Grid;

throws an error "System.InvalidOperationException" This operation is valid only on elements that have this template applied.

this particular idea i got from here

I've found loads of other ways of doing this but I cant seem to get anywhere :( hope someone can point me in the right direction :)

8728861 0 Can i specify a schema to build an XDocument while loading a xml file?

I am a xml newbie trying to create a XDocument type from a xml file.

I can validate the xml against a schema.

public class XmlHandler { public XDocument Read(string filename, string schemaname) { var schemas = this.GetSchemas(schemaname); var doc = XDocument.Load(filename); var invalid = false; doc.Validate(schemas, (o, args) => { this.OnValidationErrors(o, args); invalid = true; }); return invalid ? new XDocument() : doc; } public XmlSchemaSet GetSchemas(string schemaname) { var schemas = new XmlSchemaSet(); schemas.Add(null, schemaname); return schemas; } private void OnValidationErrors(object sender, ValidationEventArgs e) { Debug.Print("Errors: ", e); } }

But the structure of the the XDocument seems to be wrong.

When running this code

 [Fact] public void Read_get_elements() { var sut = new XmlHandler(); var result = sut.Read(this.TestFile, this.TestFileSchema); var root = result.Root; var elements = result.Elements(); var nodes = result.Nodes(); var descendants = result.Descendants(); Assert.NotEmpty(elements); }

the root variable contains the complete xml string and the the other IEnumerable variables stay empty. What am i missing?

You do not need jQuery for this. In cases where jQuery really isn't needed, I don't really suggest it. At that point it's just kind of pointless. Use regular JS where possible, use jQuery where needed.

for (var i = 0; i < pieData2.length; i++) { alert(pieData2[i].label + ' : ' + pieData2[i].value); }

If you really want to use jQuery, since $.each can iterate over arrays AND objects, you can just use it to iterate over the array and alert each.

This will iterate over each object in the array and alert each key, value pair...

$.each(pieData2, function (key, obj) { alert(obj.label + ' : ' + obj.value); });

If you need to iterate over the array and over each object (if you do not know the length), then you can do:

for (var i = 0; i < pieData2.length; i++) { for (var prop in pieData2[i]) { if (pieData2[i].hasOwnProperty(prop)) { alert(prop + ' : ' + pieData2[i][prop]); } } }

$.each(pieData2, function(obj) { $.each(pieData2[obj], function(key, value) { alert(key + ' : ' + value); }); });

Move the regex matching into a method.

You could associate the regex with a key in a hash, too, making this easier, roughly:

EMAILS = { "Berkeley": /\A[\w+-.]+@berkeley.edu\z/i, "Washington": /whatever/ }

Iterate over the hash to get the value and regex:

EMAILS.each do |school, regex| # If it matches, return the `school` value end

Use the same method for your email validation by validating :email against the method instead of a simple regex as detailed in the Custom Validation section of the Active Record Validations Guide. You may need to tweak the return value etc. to get the function to work for both things, or write a thin wrapper for the validation around the lookup.

Consider a callback to actually set the value, e.g., :after_validation or :before_save.

One example that happened to me was a sales order that had shipped and the invoice was paid, but the sales order still wasn't done. After some digging, I found that one of the procurements was still running.

I can still print the workflow from the GTK client, but isn't there some way to print it from the web client?

3323900 0 Passing double types to ceil results in different values for different optimization levels in GCC

Below, the result1 and result2 variable values are reporting different values depending upon whether or not you compile the code with -g or with -O on GCC 4.2.1 and on GCC 3.2.0 (and I have not tried more recent GCC versions):

double double_identity(double in_double) { return in_double; } ... double result1 = ceil(log(32.0) / log(2.0)); std::cout << __FILE__ << ":" << __LINE__ << ":" << "result1==" << result1 << std::endl; double result2 = ceil(double_identity(log(32.0) / log(2.0))); std::cout << __FILE__ << ":" << __LINE__ << ":" << "result2==" << result2 << std::endl;

result1 and result2 == 5 only when compiling using -g, but if instead I compile with -O I get result1 == 6 and result2 == 5.

This seems like a difference in how optimization is being done by the compiler, or something to do with IEEE floating point representation internally, but I am curious as to exactly how this difference occurs. I'm hoping to avoid looking at the assembler if at all possible.

The above was compiled in C++, but I presume the same would hold if it was converted to ANSI-C code using printfs.

The above discrepancy occurs on 32-bit Linux, but not on 64-bit Linux.

When communicating with TCP or UDP, the socket is distinguished by a 4-tuple:

local address
local port
remote address
remote port

If you leave the local assignment alone, and you are communicating with a connected protocol, the connect call will find an available local port for you. If you are restricted to a particular range of ports, then you'll need to do local address and port binding. However, in that case, since each process is only handling a single connection, I would just assign each process a unique port when it is started, rather than having it try to find an available one.

That is, assuming there is a single process responsible for starting all the other processes, that single process would decide which port should be used by the process it is about the start. This is simpler because the decision is made by a single entity, so it can use a simple algorithm, like:

for (unsigned short p = minPort; p < maxPort; ++p) { child_pid = startWorker(p); child_pid_map[child_pid] = p; }

If the child dies, the starter process can consult the child_pid_map to reuse that port immediately.

If using an external agent to assign ports is not possible, the simplest technique is to just attempt a bind call to a random port in the range. If it fails with EADDRINUSE, then incrementally try the next port number in the sequence (wrapping if necessary) until success is achieved, or you have tried all the ports.

Bulk Binds (BULK COLLECT & FORALL) and Record Processing in Oracle

Although this topic involves a much larger discussion of how to optimize database DML operations for large record sets, this approach is applicable for variable magnitudes of record volumes and even has a nice feature set, which includes a DML option called SAVE EXCEPTIONS, which enables a database operation to SKIP and continue past individual DML transactions that have encountered EXCEPTIONS.

I have adapted a script and added some additional explanatory notation to show how this works. If you would like some additional reading from the source I used, see the following link for a discussion on Oracle DML Bulk Binds and Record Processing.

The Sample Table: exception_test

Use the DDL Below to create the test table used to store the data from our procedure's Bulk Binding DML commands:

CREATE TABLE "EXCEPTION_TEST" ( "ID" NUMBER(15,0) NOT NULL ENABLE, CONSTRAINT "EXCEPTION_TEST_PK" PRIMARY KEY ("ID") ENABLE ) /

The Primary Key is the single column. It has an assigned NOT NULL constraint which will be the property used later for generating several exceptions.

Stored Procedure: proc_exam_save_exceptions

create or replace PROCEDURE proc_exam_save_exceptions IS -- Declare and Instantiate Data Types TYPE t_tab IS TABLE OF exception_test%ROWTYPE; l_tab t_tab := t_tab(); l_error_count NUMBER; ex_dml_errors EXCEPTION; PRAGMA EXCEPTION_INIT(ex_dml_errors, -24381); BEGIN -- Fill the collection. FOR i IN 1 .. 2000 LOOP l_tab.extend; l_tab(l_tab.last).id := i; END LOOP; -- Cause a failure or two. l_tab(50).id := NULL; l_tab(51).id := NULL; l_tab(1250).id := NULL; l_tab(1252).id := NULL; EXECUTE IMMEDIATE 'TRUNCATE TABLE exception_test'; -- Perform a bulk operation. BEGIN FORALL i IN l_tab.first .. l_tab.last SAVE EXCEPTIONS INSERT INTO exception_test VALUES l_tab(i); EXCEPTION WHEN ex_dml_errors THEN l_error_count := SQL%BULK_EXCEPTIONS.count; DBMS_OUTPUT.put_line('Number of failures: ' || l_error_count); FOR i IN 1 .. l_error_count LOOP DBMS_OUTPUT.put_line('Error: ' || i || ' Array Index: ' || SQL%BULK_EXCEPTIONS(i).error_index || ' Message: ' || SQLERRM(-SQL%BULK_EXCEPTIONS(i).ERROR_CODE)); END LOOP; END; END;

The first loop instantiates a collection type variable (nested table) and initializes it with a non-null value. Note the block of this procedure:

-- Cause a failure or two. l_tab(50).id := NULL; l_tab(51).id := NULL; l_tab(1250).id := NULL; l_tab(1252).id := NULL;

Which changes index positions 50, 51, 1250 and 1252 with a NULL value to force a DML error against the table constraint of the ID column on table exception_test. Compiling this procedure and executing it from the command line reveals in the DBMS OUT display a feedback message identifying the DML operations that failed by an internal count of each loop iteration...

Testing the Stored Procedure

Call the procedure to iterate through the defined DML loops and verify the BULK EXCEPTION HANDLING feature at work.

-- Command to Call Procedure begin proc_exam_save_exceptions(); end;

The following is the output of this procedure's execution:

Number of failures: 4 Error: 1 Array Index: 50 Message: ORA-01400: cannot insert NULL into () Error: 2 Array Index: 51 Message: ORA-01400: cannot insert NULL into () Error: 3 Array Index: 1250 Message: ORA-01400: cannot insert NULL into () Error: 4 Array Index: 1252 Message: ORA-01400: cannot insert NULL into () Statement processed. 0.05 seconds

An additional query of the target table shows that DML errors introduced in the middle of the loop iterations did not interrupt the completion of the other loops and their assigned DML operation.

Sample Verification of Skipped Exception Values

Additional Notes and Discussion

Here are some parting notes to keep in mind when using the SAVE EXCEPTIONS Bulk DML option:

The meta information in the error_index value of the resulting collection: SQL%BULK_EXCEPTIONS is based on the count of loop iterations from the initial cursor query of the data.

i.e., You will still need to correlate in some way that the error in loop iteration #51 (error_index = 51) lines up with whatever identifying key exists in your actual DML target tables. I recommend at least using ORDER BY clauses carefully and consistently in your DML cursors so that your loop iterations are consistently matched with the same index/key values.
There are some additional extensions to the functionality of the SAVE EXCEPTIONS and BULK DML handling alternatives that may prove to serve additional utility above traditional approaches to large volume DML operations. Among them includes: error threshold limitations (i.e., quit when a pre-defined number of DML exceptions are handled) and Bulk Processing loop size definitions.

Queries:

Query 1: Show a list of popular albums (based on number of likes)
Query 2: Show a list of most discussed albums (based on number of comments)
Query 3: Show a list of all albums of a given author on user's page
Query 4: Show the album with all photos and all comments (pull album details, show photo thumbnails of all photos in the album, show all comments of selected photo
Query 5: Show a list of related albums based on the tags of current album

Given the above schema and requirements, how should I model this in Cassandra?

I think it depends on how if/how you plan to expand upon your data model. For instance, what if you decided that you not only want to have User Events, but also, Account Events, or Login Events, and User, Accounts, and Logins are all different types of entities, but they share some Events. In that case, you would might want a normalized database model:

Users (Id int, Name varchar)
Accounts (Id int, Name varchar)
Logins (Id int, Name varchar)
Events (Id int, Name varchar)
UserEvents (UserId int, EventId int)
AccountEvents (AccountId int, EventId int)
LoginEvents (LoginId int, EventId int)

The garbage-collector does not identify and examine garbage, except perhaps when processing the Large Object Heap. Instead, its behavior is like a that of a bowling-alley pinsetter removing deadwood between throws: the pinsetter grabs all the pins that are still standing, lifts them off the surface of the lane, and then runs the sweeper bar across the lane without regard for how many pins are on that surface. Sweeping out memory wholesale is much faster than identifying individual objects to be deleted. If 1% of objects have finalizers (the real number's probably even less), then it would be necessary to examine 100 object headers to find each finalizable object. Having a separate list of objects which have finalizers makes it unnecessary for the GC to even look at any garbage objects that don't.

I have a formatted time strings from a log file of the form "08:14:59,012" and I would like to parse them as UTCTime (to be able to make some time difference and comparison operations).

I'm unable to find a way to parse the milliseconds. Here's what I have so far

Just pass in the function you want to be unique. Like this:

function reusableFunc(fn) { //reused code block here fn(); //reused code block here } var myResuableFunc1 = function (args) { reusableFunc(function () { //do your business here. }); }; var myResuableFunc2 = function (args) { reusableFunc(function () { //do your business here. }); }; //Or another way function myResuableFunc3(args) { reusableFunc(function () { //do your business here }); }

Then, you can create as many functions using the shared code as you want and, through the power of closures, pass these newly created functions around any way that you like.

You can't group inline except with an aggregate (min, max, sum, count) etc. Otherwise you are going to get the first result something is grouped on and have inaccuracies.

Can you just collapse the values of the grouping instead?

In SSRS generally with reports you have a 'details' grouping whether it is a matrix or a table report. You mentioned 'columns' so it sounds like you have header's of A, B, and C and they want to see a totals. You can generally add a grouping but then have it collapse or expand on demand. That way you present an end user with the data but they have the option of expanding it to see more if they want.

Since you did not specify if you have a matrix I will assume you have one. When you have multiple categories you can hit the grouping of a row or column and if you are having a matrix it is probably using a [SUM(field)]. The grouping of columns are showing all of them, however you can specify they are collapsed or expanded at runtime. Right Click the grouing and you get 'Group Properties'. Select the 'Visibility' pane on the left. Choose 'Hide' radio button and the default for your report will 'collapse' the values to be an aggregate instead of the expanded details of each column. If you want an option to have the user expand or collapse select the checkbox 'Display can be toggled by this report item:'. Choose a textbox or other object outside the collected scope and a user can be presented with the option to collapse or expand on default.

It's not safe to do it your way, since there may also be \r or \n in a SQL statement (e.g. a long TEXT with many lines).

If you're sure there aren't case like that, I'd suggest you to use trim() instead of str_replace(). It'll remove all spaces and EOL at the end of each lines.

<?php $tmp = trim($line); ?>

You may also specify to ONLY REMOVE EOL (both "\r\n" and "\n") like this:

<?php $tmp = trim($line, "\r\n"); ?>

Not sure I understand what you mean, but the tests you write in TDD are supposed to test your production code. They aren't tests that check user input.

To put it another way, there can be TDD unit tests that test the user input validation code, but there can't be TDD unit tests that validate the user input itself.

Depending on your XSLT processor you might first want to check whether there is support the the XPath 3.0 serialize function https://www.w3.org/TR/xpath-functions-30/#func-serialize or a built-in extension function to do the job.

If you want to perform it with XSLT then, in your template, you need to process the attributes as well, e.g.

<xsl:template match="*" mode="serialize"> <xsl:text>&lt;</xsl:text> <xsl:value-of select="name()"/> <xsl:apply-templates select="@*" mode="serialize"/> ... </xsl:template>

Be aware that worked out solutions like http://lenzconsulting.com/xml-to-string/ exist and are probably better then a quick attempt with some templates as a proper serialization which really produces namespace well-formed XML that round-trips is quite a challenge.

This would be very easy with the PHP SDK. A signed_request parameter will get passed on to your iframe, and the PHP SDK offers a function called getSignedRequest() to parse it:

https://developers.facebook.com/docs/reference/php/facebook-getSignedRequest/

For example:

$sr = $fb->getSignedRequest(); echo $sr['page']['id'];

With JavaScript it would be a lot more complicated. You could try to get the signed_request parameter like this: How to retrieve GET parameters from javascript? - But you would have to deal with the parameter on your own. Here´s how to parse the parameter on your own with PHP: https://developers.facebook.com/docs/facebook-login/using-login-with-games

No Facebook SDK needed in that case, btw. And it should also work with PHP <5.4.

Within the standard language, the approach was typically to set aside storage in an array that was larger than likely needed, but still within the constraints of the platform running the program, then manually parcel that storage out as required. The language had features, such as sequence association, storage association, and adjustable arrays, that helped with this parcelling.

Use of language extensions for dynamic memory management was also common.

The capabilities of Fortran 77 and earlier need to be considered in the context of the capabilities of the platforms of the time.

4555057 0 UML and java classes

I do need your valuable help. A few weeks ago I developed a small program in Java. Probably a wrong approach, but I didn't tackle the problem with UML in mind, but on the basis of a given idea I built a fully functional piece of software which lives up to expectations.

The program itself consist of two classes and several methods.

Now I need to draw the corresponding UML class diagram and it seems a very knotty problem for me.

Since the UML class diagram aims at showing the source code dependencies between classes, I'm wondering how I can draw a class diagram based on the following code.

.................................................................

import javax.swing.JPanel; class WavPanel extends JPanel {

 List<Byte> audioBytes; List<Line2D.Double> lines; public WavPanel() { super(); setBackground(Color.black); resetWaveform(); } public void resetWaveform() { audioBytes = new ArrayList<Byte>(); lines = new ArrayList<Line2D.Double>(); repaint(); } }

................................................................

In a nutshell, the WavPanel class is an example of inheritance. The JPanel class (part of a package) acts as a superclass. How can I solve the problem? My concern is that JPanel is a class which is part of a package.

Furthermore, in order to draw a good class diagram am I wrong in thinking that maybe I had to do the UML diagram first and then write the associated code?

The fact that I wrote several methods (instead of classes) and just a few classes, can that be a problem with UML? If so it would mean reengineering the entire software again.

Thanks in advance . Any help will be highly appreciated.

I would suggest you this approach:

Split userInput string by white spaces: userInput.split("\\s+"). You will get an array. See String.split()
For question 1: iterate over the array comparing each string with your keyword. See String.equals() and String.equalsIgnoreCase().
For question 2: add the array to a Set. As this can't contain any duplicate item, its size will give you the answer.

17060285 0 Java: double: how to ALWAYS show two decimal digits

I use double values in my project and i would like to always show the first two decimal digits, even if them are zeros. I use this function for rounding and if the value I print is 3.47233322 it (correctly) prints 3.47. But when i print, for example, the value 2 it prints 2.0 .

public static double round(double d) { BigDecimal bd = new BigDecimal(d); bd = bd.setScale(2, BigDecimal.ROUND_HALF_UP); return bd.doubleValue(); }

I want to print 2.00!

Is there a way to do this without using Strings?

Thanks!

EDIT: from your answers (wich I thank you for) I understand that I wasn't clear in telling what I am searching (and I'm sorry for this): I know how to print two digits after the number using the solutions you proposed... what i want is to store in the double value directly the two digits! So that when I do something like this System.out.println("" + d) (where d is my double with value 2) it prints 2.00.

I'm starting to think that there is no way to do this... right? Thank you again anyway for your answers, please let me know if you know a solution!

25965636 0 MySQL count a number of entries within time period sharing at least 1 of 3 columns

I have a table that logs invalid user login attempts. Every time an invalid attempt is made, the username, user IP, user email and time/date is stored in the database.

What I'd like to do is check if within ANY 24 hour time period there has been more than X invalid attempts by the same user. However, the users can change the email, username or IP at any point. So, I need to check that anyone of these 3 fields is in common.

For example:

User ID: 1; IP: 1.1.1.1; Email: test@test.com
User ID: 2; IP: 1.1.1.1; Email: test2@test.com
User ID: 1; IP: 1.1.1.2; Email: test3@test.com
User ID: 4; IP: 1.1.1.4; Email: test@test.com
User ID: 5; IP: 1.1.1.4; Email: test5@test.com

All of these would match as the SAME user because they share EITHER the user ID, the IP or the email. Then I need to output all user IDs, IPs and emails so I can ban any user in another table that matches these criteria.

You say you're outputting a csv. Are you sure your data fields have no commas in them? That can manifest as "extra" columns when you read the csv file. Or does your "NAME" field have single-quotes and commas in it that might break your explicit double-quoting?

Look at the records with "extra" fields in them & trace back to your source data. The first spurious value will tell you where the breakage is.

the controls have an opacity when moving which by default is set to 0.4. To prevent that you can do this:

canvas.item(0).set({ borderOpacityWhenMoving: 1 });

As far as I know the control knobs cannot be changed. You'd have to change the function that actually draws the controls. This is done in the function drawControls which either uses strokeRect or fillRect depending on the settings to draw the controls. You should be able to change the function to draw a circle.

hope this helps.

this.x and this.y are functional from the scope of your checkers pieces object; however, if you're accessing a piece outside of their scope, you must use a piece's instance name. Although not optimal, you could loop through children DisplayObjects.

// create a collection of your checker pieces var checkers:Array = []; // create a checker piece, whatever your DisplayObject class is. var checker:Checker; checkers.push(checker); // add it to the stage, probably your game board addChild(checker); checker.x = 100; checker.y = 100; // loop through the children (from your game board) for (var i:uint = 0; i < numChildren; i++) { var checker:DisplayObject = getChildAt(i); trace(checker.x); trace(checker.y); }

Using coordinates to reference a piece may not be optimal for game play. You might want to consider a row / column or approach it from how your game board works.

If this is not clear, you should specify some code or expand your question with more detail.

Stunnel does almost exactly what you ask if the following conditions are met.

One stunnel instance must be running for each service (either from inetd or in standalone daemon-like mode).
The system running cURL must manually resolve the hostname of the target service to the IP address of the host running stunnel (e.g. /etc/hosts) in order to use it.

I used stunnel in a similar way for connecting to IRC servers using SSL with SSL-capable clients. It works like a charm, one important thing to be careful about is the incompatibilities between the 3.x and newer versions. If you're planning for a new system, you should probably use the new ones.

27003353 0 C# simple code to write an INSERT query is giving an exception

I have a very basic and beginner problem. I got a 5 line code and I got exception in that.

My database : Table -> id,name

It has one table and two columns inside the table viz. id and name. I made a form.

Here is my code:

private void button1_Click(object sender, EventArgs e) { SqlConnection conn = new SqlConnection("Data Source=(LocalDB)\\v11.0;AttachDbFilename=\"C:\\Users\\Nicki\\documents\\visual studio 2012\\Projects\\WindowsFormsApplication2\\WindowsFormsApplication2\\Database2.mdf\";Integrated Security=True"); conn.Open(); SqlCommand command = new SqlCommand("INSERT INTO Table (id,name) VALUES (1,'" + textBox1.Text + "')", conn); command.ExecuteNonQuery(); conn.Close(); }

I get the following exception on running the code:

It says that I have syntax error even though the syntax error is correct. Any help would be appreciated.

Thankyou!

16806021 0 Friends and nested classes

Ok I'm totally frazzled on this. Code is begin to swim around the screen...must sleep.

So! Ok, troubled by nested classes and friends.

here is the pseudo-code

 class A{ public: //constructor // member functions private: class B{ //private int a(); }; class C{ //private int b(); }; };

So once an object of type A has been created, I would like it to access a() and b(). I know that I have to use a friend function for this. So where should I put friend class A. Is that the right expression?.

6015196 0 Method to change self-closing tags to explicit tags in Javascript?

Does there exist a method or function that can convert the self-closing tags to explicit tags in Javascript? For example:

<span class="label"/>

converted to :

<span class ="label"></span>

I would like to copy a new HTML from the iframe to the outerHTML of the main page, as the new HTML generated contains self-closing tags, the outerHTML doesn't recognize them and then doesn't change and the page doesn't show correctly. But when the format is standard, that is,with the non-self-closing tags, the outerHTML will take the new HTML,and the page shows perfectly.This is why I would like to change the tags.

And this html is in a string

In fact, I don't want to parse HTML, I just want to find the "< span.../>"and replace it with "< span...>< /span>"

Your approach is ok, but you can make something more generic, like storing the config data for Redis in a file or passing the host and port like arguments:

node app.js REDIS_HOST REDIS_PORT

Then in your app you can grab them using process.argv:

app.configure('development', function(){ app.use(express.errorHandler({ dumpExceptions: true, showStack: true })); var r = require("redis").createClient(process.argv[2], process.argv[3]); }); app.configure('production', function(){ app.use(express.errorHandler()); var r = require("redis").createClient(process.argv[2], process.argv[3], { detect_buffers: true }); });

Update:

Express will know in what environment you're in by looking at the NODE_ENV variable (process.env.NODE_ENV): https://github.com/visionmedia/express/blob/master/lib/application.js#L55

You can set that variable when starting the app like so: NODE_ENV=production node app.js (recommended), setting process.env.NODE_ENV manually in your node app before the Express code or putting that env var in ~/.profile like Ricardo said.

@Saurabh Nanda: Similar to what you posted, you can also create a simple function to convert your varchar array to lowercase as follows:

CREATE OR REPLACE FUNCTION array_lowercase(varchar[]) RETURNS varchar[] AS $BODY$ SELECT array_agg(q.tag) FROM ( SELECT btrim(lower(unnest($1)))::varchar AS tag ) AS q; $BODY$ language sql IMMUTABLE;

Note that I'm also trimming the tags of spaces. This might not be necessary for you but I usually do for consistency.

Testing:

SELECT array_lowercase(array['Hello','WOrLD']); array_lowercase ----------------- {hello,world} (1 row)

As noted by Saurabh, you can then create a GIN index:

CREATE INDEX ix_tags ON tagtable USING GIN(array_lowercase(tags));

And query:

SELECT * FROM tagtable WHERE ARRAY['mytag'::varchar] && array_lowercase(tags);

UPDATE: Performance of WHILE vs array_agg/unnest

I created table of 100K 10 element text[] arrays (12 character random mixed case strings) and tested each function.

The array_agg/unnest function returned:

EXPLAIN ANALYZE VERBOSE SELECT array_lowercase(data) FROM test; QUERY PLAN ------------------------------------------------------------------------------------------------------------------------ Seq Scan on public.test (cost=0.00..28703.00 rows=100000 width=184) (actual time=0.320..3041.292 rows=100000 loops=1) Output: array_lowercase((data)::character varying[]) Total runtime: 3174.690 ms (3 rows)

The WHILE function returned:

EXPLAIN ANALYZE VERBOSE SELECT array_lowercase_while(data) FROM test; QUERY PLAN ------------------------------------------------------------------------------------------------------------------------ Seq Scan on public.test (cost=0.00..28703.00 rows=100000 width=184) (actual time=5.128..4356.647 rows=100000 loops=1) Output: array_lowercase_while((data)::character varying[]) Total runtime: 4485.226 ms (3 rows)

UPDATE 2: FOREACH vs. WHILE As a final experiment, I changed the WHILE function to use FOREACH:

CREATE OR REPLACE FUNCTION array_lowercase_foreach(p_input varchar[]) RETURNS varchar[] AS $BODY$ DECLARE el text; r varchar[]; BEGIN FOREACH el IN ARRAY p_input LOOP r := r || btrim(lower(el))::varchar; END LOOP; RETURN r; END; $BODY$ language 'plpgsql'

Results appeared to be similar to WHILE:

EXPLAIN ANALYZE VERBOSE SELECT array_lowercase_foreach(data) FROM test; QUERY PLAN ------------------------------------------------------------------------------------------------------------------------ Seq Scan on public.test (cost=0.00..28703.00 rows=100000 width=184) (actual time=0.707..4106.867 rows=100000 loops=1) Output: array_lowercase_foreach((data)::character varying[]) Total runtime: 4239.958 ms (3 rows)

Though my tests are not by any means rigorous, I did run each version a number of times and found the numbers to be representative, suggesting that the SQL method (array_agg/unnest) is the fastest.

1751540 0 specifying column names of a data frame within a function ahead of time

Suppose you're trying to create a data frame within a function. I would like to be able to define the column names ahead of time as one of the parameters of the function. Take the following code:

 foo <- function(a) { answer <- data.frame(a=1:5) return(answer) }

In the above example, I would like to be able to specify the value of the column name in the function foo(), e.g. foo('my.name') so that answer has the column name my.name instead of a. I imagine you could code this up within the function using colnames(), but I was interested in an alternative approach.

33835975 0 Does provisioning have a place in the Drupal world?

My team is relatively new to Drupal. One thing we have struggled to understand is how to work with it from a DevOps point of view. I realize this is too large a subject for one question so I have a more specific question that gets at the heart of the matter.

How does one provision a Drupal instance? By "provision", I mean create a provisioning script that builds my CMS (we're only using Drupal for that purpose) starting with a clean virtual machine with only OS and web server. The script would install and configure Drupal and its modules and connect to an existing database containing my content. Or perhaps I can even have it add my content to Drupal instance with an empty database. I'm just not sure what makes sense.

What I am trying to avoid is the uncertainty and non-reproducability that comes with doing everything interactively via Drupal's UI. I realize that Drupal has lots of techniques for exporting various things but there doesn't appear to be any coherent overall picture. Every bit of advice is of the form, "If you want to do (some specific thing), this is how you might do it." Or, even worse, "This worked for me." Neither of these things gives me much confidence or, more importantly, gives decent "best practices" advice that tells us what Drupal's designers intended.

There are some Drupal "best practices" articles but they don't go much beyond advice such as, "Do a backup before changing anything." I need more useful advice.

The problem is that your data coming asynchronously but you try save them synchronously. Step by step:

You define variable trail = []
You return trail variable to controller
Server responds with data (but you already return trail)

You can solve this problem by using next code:

app.service("dataService", function ($http, $routeParams){ this.getSingleTrail = function (){ var trail = []; return $http.get("http://localhost:8080/DMW-skeleton-1.0/trail/findTrailByTrailId/" + $routeParams.trailId); }}) app.controller("searchTrailsCtrl", function ($scope, dataService ) { $scope.trail; dataService.getSingleTrail().success(function(data){ $scope.trail = data; }); })

Rapheal doesn't have setters for width and height on the Paper object, so calling them is not affecting the DOM, but just setting some properties on the Paper object.

Passing in the width and height params in the constructor will affect the SVG tag in the DOM.

If you want to change the paper's width and height after constrcution, you can set the style properties of the SVG tag like so:

var paper = Raphael(domid); paper.canvas.style.width = '200px'; paper.canvas.style.height = '100px';

As Kevin mentioned, it's probably better to use the setSize method to handle runtime resizing.

eg)

paper.setSize(200,100)

Hope that helps.

If you want to maintain your own version of LibraryB you have a few options:

You can make LibraryB inherent part of your project: just remove or comment out [remote "LibraryB"] section in the config file, and make changes to LibraryB inside your project.

The disadvantage is that it would be harder to send patches for canonical (third-party) version of LibraryB
You can continue using 'subtree' merge, but not from the canonical version of LibraryB, but from your own clone (fork) of this library. You would change remote.LibraryB.url to point to your local version, and your local version would be clone of original LibraryB. Note that you should merge your own branch, and not remote-tracking branch of canonical LibraryB.

The disadvantage is that you have to maintain separate clone, and to remember that your own changes (well, at least those generic) to LibraryB have to be made in the fork of LibraryB, and not directly inside ProjectA.
You might want to move from 'subtree' merge which interweaves history of ProjectA and LibraryB, to having more separation that can be achieved using submodule (tutorial). In this case you would have separate repository (fork) of LibraryB, but it would be inside working area of ProjectA; the commit in ProjectA would have instead of having tree of LibraryB as subtree, pointer to commit in LibraryB repository. Then if you do not want to follow LibraryB development, it would be enough to simply not use 'git submodule update' (and perhaps just in case comment out or remove link to canonical version of LibraryB).

This has the advantage of making it easy to send your improvements to canonical LibraryB, and the advantage that you make changes inside working area of ProjectA. It has disadvantage of having to learn slightly different workflow.

Additionally there is also an issue of how to go from 'subtree' merge to submodules. You can either:
- Move from subtree merge to submodule by creating git repository in the subproject subtree in superproject working repository (i.e. "git init" inside appropriate subdirectory + appropriate "git submodule init" etc.). This means that you would have 'subtree' up to some point of history, and submodule later.
- Rewrite history using git filter-branch to replace subtree merge by submodule. This has the disadvantage of rewriting history (big no if somebody based his/her work on current history), and advantage of 'clean start'. Or you can wait a bit for "git submodule split" (thread on git mailing list) to make it into git...
  Unfortunately Splitting a git repository blog posts returns "host not found"

I hope that this version solve your problem.

Disclaimer: I have used neither subtree merge, nor submodules, nor git-filter-branch personally.

By the looks of a comment you left in another answer given (to the effect of getting the same error message), it sounds like you need to escape the entered data, including if(!mysqli_query($con,$sql)) which is a contributing factor. - See further down below.

Using the following may very well fix the problem.

$con=mysqli_connect('localhost','root','root','secure_login'); // place this first if (mysqli_connect_errno()) { echo "Failed to connect to MySQL: " . mysqli_connect_error(); } $username = stripslashes($_POST['username']); $password = stripslashes($_POST['password']); $repassword = stripslashes($_POST['repassword']); $username = mysqli_real_escape_string($con,$_POST['username']); $password = mysqli_real_escape_string($con,$_POST['password']); $repassword = mysqli_real_escape_string($con,$_POST['repassword']); ... $sql = mysqli_query($con,"INSERT INTO users (username, password) VALUES ('".$username."','".$password."')"); ...

You also need to change:

if (!mysqli_query($con,$sql)){...}

if (!$sql){...}

you're querying twice with mysqli_query and connecting twice, which is a contributing factor, then again, it may very well be "thee" reason which I suspect it is.

Consult this answer given by Marc B who states what is happening with a similar problem. His explanation will shed some light on the subject.

About password storage

I must also note that storing passwords in plain text is unsafe.

You'd be better off using CRYPT_BLOWFISH or PHP 5.5's password_hash() function. For PHP < 5.5 use the password_hash() compatibility pack and use prepared statements.

Plus as I stated in my comment;

You don't need this mysql_select_db("secure_login", $con); for two reasons.

1) You're already selecting a DB. mysqli_connect('localhost','root','root','secure_login')

2) You're mixing MySQL APIs - Those are two different APIs, and they do not mix together.

...and the fact about the missing quote for $password in ('$username',$password')

First line -- a table scan (see NULLs and ALL)

2nd and 4th line -- an index scan ("Using index"), but rather costly since 10K rows needed.

What it does not tell you is whether some other index(es) would be more efficient. Nor does it tell you whether reformulating the query would help. Please provide us with the SELECT so we can help you there, plus tie more things to the EXPLAIN.

The header file (.h) is the programmer's interface to your module. Anything a user (programmer) of your module needs to know to use your module should be in there, but put the actual implementations in the associated .c file. Generally, you put the function prototypes (e.g. int f(void);) in the .h file and the definitions (the implementations, e.g. int f(void) { return 1; }) in the .c file. The linker matches the prototype to the definition because the function signatures match (the name, argument types, and return type). One way to think about it is the .h file as what you share with everyone, and the .c file as what you keep to yourself.

If you want a user of your module to have access to STUDENT_SIZE, then put

#define STUDENT_SIZE 20

in your .h file instead of your .c file. Then, any file with

#include "stud.h"

would have your macro for STUDENT_SIZE. (Notice the file name is "stud.h" not "stud".)

Lets say i want to use STUDENT_SIZE in another file whats the syntax? Do i need to use stud.STUDENT_SIZE?

No. You might be confusing this with namespaces, which C does not have in the same sense as other languages like C++, Java, etc. Just use STUDENT_SIZE. (This is why it is important to not use existing identifiers, and also why many people frown upon macros.)

... i want from another file to access some of the functions inside stud.c.

If you want another file to have access to some function in stud.c, then put that function's prototype in stud.h. This is precisely what the header file is for.

... if i want to lets say make an array of students:

struct stud students[STUDENT_SIZE];

Can i access that normally like students[5].stud_id ?

As you have written your header file, no. You might know some struct stud exists, but you don't know what the members are called (i.e. you wouldn't know stud_id exists). The reason is that the user of your module sees only what is in the header file, and you defined no members of the struct in your header file. (I'm surprised what you have written even compiles, because you define struct stud twice, once empty {}, and once with members.) Again, if you want the programmer user to have access to the members of struct stud, its definition

struct stud { char stud_id[MAX_STR_LEN]; char stud_name[MAX_STR_LEN]; struct grade Grade[MAX_STRUCT]; struct income Income[MAX_STRUCT]; };

belongs in your header file (along with whatever those other macros are). Without knowing this, the programmer (and the compiler) has no idea what the members of struct stud are.

(You didn't ask about this, but if you want to share access to a global variable in your .c file, then declare it with the keyword extern in your .h file, and without extern in your .c file. See How to correctly use the extern keyword in C for more.)

20441633 0 Restrict scope of variable within include file in php

I am facing variable conflicting issues in application i am designing.

e.g in one of my web application page, there are two modules

i: tag clouds module ii: photo listing module

both have variable $listOrder , e.g when script processing module "tag cloudes" it set $listOrder = "tagid desc" as its not set initially.

if(!isset($listOrder)) $listOrder = "tagid desc";

When script reach to photo listing module again it try to process the following line as shown above. as variable is already set in tag cloud list. it keeps "tagid desc" as value. which causes sql error as "tagid" is not a field of photo listing.

This is simple example there are more than 4 or 5 modules with lots of similar variables in every page, which cause conflicts.

Can we do something to restrict scope of variable to module level in php to avoid such conflicts.

35211170 0 carrierwave backgrounder s3 recreate_versions

I'm trying to follow https://github.com/carrierwaveuploader/carrierwave/wiki/How-to%3A-Recreate-and-reprocess-your-files-stored-on-fog instructions, but I was getting errors. my file is called hat.jpg

I'm using carrierwave_backgrounder so i needed these instructions to process immediately.

with_avatar.each do |instance| begin instance.process_avatar_upload = true instance.avatar.cache_stored_file! instance.avatar.retrieve_from_cache!(instance.avatar.cache_name) instance.avatar.recreate_versions! instance.save! rescue => e Rails.logger.info("ERROR: UserAvatar: #{instance.id} -> #{e}") end end

So, i tried it in my console one line at a time. If I set process_avatar_upload = true, the next line fails

undefined method `cached?' for nil:NilClass

If i run the same command again i get

undefined method `content_length' for nil:NilClass

Finally, if I run a third time, it seems to work. However, when i get to the recreate_versions! I get this:

No such file or directory [my file path]/uploads/tmp/1454615129-9112-7053/square_hat.jpg

Its correct, there is no square, because that's what I'm trying to create.

How can I recreate my versions on s3? I have a lot of them to do. Thanks.

The technical difference is the presence of get and set accessors. You can customize either or both to do more that just get or set the value.

The practical difference is that many data-binding methods (including most if not all of the .NET controls) use reflection to bind to properties only - they do not support binding to fields directly.

If you plan to bind the properties of your class to a UI control (DataGrid, TextBox, etc.), or if there's the slightest chance that you might customize the get/set accessors in the future, then make the properties. It is a breaking change to change a field to a property.

Many coding standards (including FxCop) hold that you should use properties instead of fields for public data.

If lines of code are a concern you can use auto-implemented properties:

class Class2 { public static int A {get; set; } }

You can later add logic to the get/set accessors without breaking users of your class.

29919674 0 How to use dependent bundles in different container in Fabri8?

I am trying to understand the capabilities of Fabric8's container management. I just want to clarify weather the following scenario can be achieved by using Fabric8 in JBossFuse.

I have created simple 2 bundles (tick, tock bundles inspired by the : http://kevinboone.net/osgitest.html). Simply Tick bundle is exporting a package and Tock bundle is importing it. In another words, Tock Bundle depends on the Tick Bundle.

These 2 bundles are working perfectly when deployed in a single container (say in a one child container in JBoossFuse).

Then I have created a cluster by using the fabric8 and added its containers to the Fabric Ensemble as well.

And I have created 2 profiles. TickProfile contains the Tick bundle and Tock profile contains the Tock bundle.

I have deployed above 2 profiles in 2 different containers as follows,

enter image description here

Then it is not working properly because Tock bundle cannot resolve its dependency of Tick Bundle which is exposed by Tick Bundle (because those bundles are in two different containers).

I thought this is possible with fabric8 but it seems it cannot.

It would be really appreciated if someone can tell me whether there is any way of achieving this.

Thanks.

The rate at which the capacity of a vector grows is implementation dependent. Implementations almost invariable choose exponential growth, in order to meet the amortized constant time requirement for the push_back operation. What amortized constant time means and how exponential growth achieves this is interesting.

Every time a vector's capacity is grown the elements need to be copied. If you 'amortize' this cost out over the lifetime of the vector, it turns out that if you increase the capacity by an exponential factor you end up with an amortized constant cost.

This probably seems a bit odd, so let me explain to you how this works...

size: 1 capacity 1 - No elements have been copied, the cost per element for copies is 0.
size: 2 capacity 2 - When the vector's capacity was increased to 2, the first element had to be copied. Average copies per element is 0.5
size: 3 capacity 4 - When the vector's capacity was increased to 4, the first two elements had to be copied. Average copies per element is (2 + 1 + 0) / 3 = 1.
size: 4 capacity 4 - Average copies per element is (2 + 1 + 0 + 0) / 4 = 3 / 4 = 0.75.
size: 5 capacity 8 - Average copies per element is (3 + 2 + 1 + 1 + 0) / 5 = 7 / 5 = 1.4
...
size: 8 capacity 8 - Average copies per element is (3 + 2 + 1 + 1 + 0 + 0 + 0 + 0) / 8 = 7 / 8 = 0.875
size: 9 capacity 16 - Average copies per element is (4 + 3 + 2 + 2 + 1 + 1 + 1 + 1 + 0) / 9 = 15 / 9 = 1.67
...
size 16 capacity 16 - Average copies per element is 15 / 16 = 0.938
size 17 capacity 32 - Average copies per element is 31 / 17 = 1.82

As you can see, every time the capacity jumps, the number of copies goes up by the previous size of the array. But because the array has to double in size before the capacity jumps again, the number of copies per element always stays less than 2.

If you increased the capacity by 1.5 * N instead of by 2 * N, you would end up with a very similar effect, except the upper bound on the copies per element would be higher (I think it would be 3).

I suspect an implementation would choose 1.5 over 2 both to save a bit of space, but also because 1.5 is closer to the golden ratio. I have an intuition (that is currently not backed up by any hard data) that a growth rate in line with the golden ratio (because of its relationship to the fibonacci sequence) will prove to be the most efficient growth rate for real-world loads in terms of minimizing both extra space used and time.

27686169 0 PHP: calculate array values by array

This may be simple to some of you guys but I'm really dummy in php. All what I need is just to transform a multidimensional array and calculate some of it's sub array values.

 Array ( [0] => Array ( [date] => 2014-10-30 [mission] => one [point] => 10 ) [1] => Array ( [date] => 2014-10-31 [mission] => five [point] => 10 ) [2] => Array ( [date] => 2014-11-19 [mission] => one [point] => 8 )

And the output would be like:

 Array ( [one] => Array ( [mission] => one [point] => 18 // sum all points where [mission] => one [count] => 2 [everage] => 9 // 18/2 ) [five] => Array ( [mission] => five [point] => 10 [count] => 1 [everage] => 10 )

It is simple to get the sum of [point] values using foreach but troubles begin when I try to get count of arrays with same [mission] value. Thats my code:

foreach($missionsarray as $row) { if(!isset($newarray[ $row['mission'] ])) { $newarray[ $row['mission'] ] = $row; $newarray[ $row['mission'] ]['count'] = count($row['point']); continue ; } $newarray[ $row['mission'] ]['point'] += $row['point']; } print_r($newarray);

24002066 0 Progress Bar during the loading of a ListView

So, I want to display a spinning loading indicator while my ListView is being populated. I successfully have implemented the progress bar, BUT for some reason it disappears BEFORE all of the listings are displayed. What I want is the progressbar to be present during the TOTAL load time of the listings. Basically, what it seems like, each listing is being displayed one at a time, not all at once when they are all loaded. What I'm doing is 1. Creating a new custom adapter class 2. Populating the ListView in an AsyncTask using this adapter class 3. Setting the ListView to this adapter

This works properly, the progress bar just disappears before all of the listings are displayed. Does anyone have any ideas?

Basically:

#info is used to discover information about a XMPP entity.
#item is used to discover items associated with a XMPP entity.

#info query results will show you amongst others the supported features of a XMPP entity (e.g. XHTML-IM support).

#item query results will show the available items of a XMPP entity. For example the XEP-0045 MUC component of a XMPP service. But any other available service/component could show up here.

One could also say that #info is used to query the features of this particular entity, while #items is used to query for "sub-components" of that entity, which itself are usually be queried with #info for their features.

The problem with the date format is because you are converting it to a string and then back to a DateTime value. Depending on the culture settings on the specific server this may or may not work. It may also misinterpret the data, e.g. transforming a date from 2013-10-12 to 2013-12-10.

DateTime datet = new DateTime(year,month,day); startDateParam.Value = datet; endDateParam.Value = datet;

"note that the server stored datetime with format '1900-01-01 00:00:00.000'"

3727398 0 sql server stock quote every second

I have a table with stock quotes

Symbol

QuoteDateTime

Using SQL Server 2008, lets say for any given 60 second time period I want to select quotes on all symbols so that there is a record for every second in that time period.

Problem is not every symbol has the same number of quotes - so there are some seconds that have no quote record for any given symbol. So I want to fill in the missing holes of data. So if ORCL has quotes at second 1, 2, 3, 5, 7, I want the result set that has 1,2,3,4,5,6,7...up to 60 sec (covering the whole minute). The values in row 4 come from row 3

In this scenario I would want to select the previous quote and use that for that particular second. So there is continuous records for each symbol and the same number of records are selected for each symbol.

I am not sure what this is called in sql server but any help building a query to do this would be great

For output I am expecting that for any given 60 sec time period. For those symbols that have a record in the 60 seconds, there will be 60 records for each symbol, one for each second

29044041 0 Is there a way to use UITextField's on a dynamic UITableView, AND 'tab' between them?

This may be a tad lengthy, but bear with me. It's mostly simple code and log output. Normally, if I wanted to have a UITextField as a part of a UITableViewCell, I would likely use either a) static rows or b) I would create the cell in the storyboard, outlet the cell and outlet the field to my ViewController, and then drag the cell outside of the "Table View", but keeping it in the scene.

However, I need to create a View where I accept input from 28 various things. I don't want to outlet up 28 different UITextField's.

I want to do this dynamically, to make it easier. So I've created a custom UITableViewCell with a Label and UITextField.

My ViewController has two arrays.

@property (nonatomic, strong) NSArray *items; @property (nonatomic, strong) NSArray *itemValues;

My cellForRowAtIndexPath looks something like this...

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSString *cellIdentifier = @"ItemCell"; MyItemTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath]; if (!cell) { cell = [[MyItemTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier]; cell.categoryValue.tag = indexPath.row; cell.categoryValue.delegate = self; } cell.item.text = [self.items objectAtIndex:indexPath.row]; cell.itemValue.text = [self.itemValues objectAtIndex:indexPath.row]; return cell; } - (BOOL)textFieldShouldReturn:(UITextField *)textField { NSInteger tag = [textField tag]; NSLog(@"TFSR tag: %zd/%zd", tag, self.categories.count-1); if (tag < (self.categories.count - 1)) { NSIndexPath *nextIndex = [NSIndexPath indexPathForRow:tag+1 inSection:0]; NSLog(@"TFSR nextRow: %zd/%zd\n", nextIndex.row); FFFCategoryTableViewCell *cell = (MyItemTableViewCell *)[self.tableView cellForRowAtIndexPath:nextIndex]; [self.tableView scrollToRowAtIndexPath:nextIndex atScrollPosition:UITableViewScrollPositionMiddle animated:YES]; [cell.categoryValue becomeFirstResponder]; } else { NSLog(@"DONE!"); } return YES; }

This is proving to be problematic. The goal is, the user should be able to select the UITextField on the first row, enter a value, and when they hit the 'Next' key on the keyboard, they will be sent to the UITextField on the second row. Then 3rd, 4th,... 27th, 28th.

However, let's say I first highlight the UITextField on the Cell with IndexPath.row = 11. If I tap 'Next', this is what my output looks like...

======== OUTPUT ======== TFSR tag: 11/27 TFSR nextRow: 12/27 TFSR tag: 12/27 TFSR nextRow: 13/27 TFSR tag: 13/27 TFSR nextRow: 14/27 TFSR tag: 0/27 TFSR nextRow: 1/27

Now I fully understand why this is happening. With UITableView trying to save memory in loading various cells, and with the use of dequeueReusableCellWithIdentifier... I only have 14 cells (0-13). Then it loops back to the beginning.

My problem is... I don't know a solution to this problem. I want the user to be able to his Next until the 28th UITextField row.

Any ideas/solutions on how I could achieve this?

Are you sure the font is loaded correctly?

You can try:

for (NSString *familyName in [UIFont familyNames]) { NSLog(@"%@", familyName); for (NSString *fontName in [UIFont fontNamesForFamilyName:familyName]) { NSLog(@"\t%@",fontName); } }

This will show you all the fonts that are loaded. Make sure the same name "Cabin-Regular" is showing up exactly the same. A lot of times the font itself isn't loaded and then the font-size won't be used at all.

I'm using PHP Simple HTML DOM Parser to scrape some data of a webshop (also running XAMPP 1.7.2 with PHP5.3.0), and I'm running into problems with <tbody> tag. The structure of the table is, essentialy (details aren't really that important):

<table> <thead> <!--text here--> </thead> <tbody> <!--text here--> </tbody> </table>

Now, I'm trying to get to the <tbody> section by using code:

$element = $html->find('tbody',0)->innertext;

It doesn't throw any errors, it just prints nothing out when I try to echo it. I've tested the code on other elements, <thead>, <table>, even something like <span class="price"> and they all work fine (ofcourse, removing ",0" fails the code). They all give their correct sections. Outertext ditto. But it all fails on <tbody>.

Now, I've skimmed through the Parser, but I'm not sure I can figure it out. I've noticed that <thead> isn't even mentioned, but it works fine. shrug

I guess I could try and do child navigation, but that seems to glitch as well. I've just tried running:

$el = $html->find('table',0); $el2 = $el->children(2); echo $el2->outertext;

and no dice. Tried replacing children with first_child and 2 with 1, and still no dice. Funny, though, if I try ->find instead of children, it works perfectly.

I'm pretty confident I could find a work-around the whole thing, but this behaviour seems odd enough to post here. My curious mind is happy for all the help it can get.

40341145 0 Can run_loop use a different identifier for resigning DeviceAgent-Runner.app

Setup:

Xcode 8
OSX El Capitan (10.11.6)
Physical iPhone6 (iOS 9.1)
calabash-cucumber 0.20.3
Run_loop 2.2.2

First I tried to start the calabash console on the physical phone, but because it didn't have the DeviceAgent-Runner.app app it tried to install it.

As you can see it fails to install the DeviceAgent-Runner.app app with a timeout.

Then I tried to install the DeviceAgent-Runner.app manualy

Which gave me at least some more info, as it said it is related to code singing. I am sure that my certificats are valid. So my open questions:

Can I tell run_loop to use a different identifier for resigning DeviceAgent-Runner.app, because I can't use a wildcard certificate (company policy).
Or any other ideas how to continue from this point

Thanks!

The php code you show (which really just sends the work to convert in a shell) does not check to see if the images have alpha channels, it just takes whatever file is given and turns it on. If it already had one there would be no file change, but convert is not being asked to make any decision based on the status, just go ahead and add the channel.

Your question is not clear enough, However lets say that the code above is working.

You want to add the result every time you preforms this operation (I assume).
again assuming you're using windows forms.
put a comboBox on your form.

then when preforming the operation you need to keep a list of what you got before then use it as dataSource for the comboBox. The code below demonstrate this:

 List<string> dataList = new List<string>(); // this line is global not inside a closed scoop var myDataTable = new System.Data.DataTable(); using (var conection = new System.Data.OleDb.OleDbConnection("Provider=Microsoft.JET.OLEDB.4.0;" + "data source="+foldername+"\\Program\\Ramdata.mdb;Jet OLEDB:Database Password=****")) { conection.Open(); var query = "Select u_company From t_user"; var command = new System.Data.OleDb.OleDbCommand(query, conection); var reader = command.ExecuteReader(); while (reader.Read()) { profselect.Text = reader[0].ToString(); dataList.Add(profselect.Text); } } myComboBox.DataSource = dataList; myComboBox.SelectedText = dataList.Last();

that as far as I can help with this much information you gave.

35669173 0 Clojure destructure map using :keys with qualified keywords not working

I've tried this with both 1.7.0 and 1.8.0 and it appears that Clojure does not destructure maps using :keys whose keys are fully qualified. I don't think it has to do with being in the tail on the arguments as it doesn't work when I switch around the function argument positions as well.

(ns foo.sandbox) (def foo ::foo) (def bar ::bar) (defn normalize-vals [mmap & [{:keys [foo bar] :as ops}]] (println "normalize-vals " ops " and foo " foo " bar" bar)) (normalize-vals {} {foo 1 bar 2}) => normalize-vals {:foo.sandbox/foo 1, :foo.sandbox/bar 2} and foo nil bar nil

However; this works:

 (defn normalize-vals [mmap & [{a foo b bar :as ops}]] (println "normalize-vals " ops " and foo " a " bar" b)) (normalize-vals {} {foo 1 bar 2}) => normalize-vals {:cmt.sandbox/foo 1, :cmt.sandbox/bar 2} and foo 1 bar 2

Is this a defect?

It depends if you are using any MVVM model or not.

My suggestion, if you are not using a MVVM, is to use Blend Sample data, is fast and quick.

If you are MVVM Light I've found very usefull to create two files: DataService.cs - contains the real connection and data DesignDataService.cs - contains the sample data

The two libraries are identical, from an call perspective so that in the ViewModelLocator you can swap them:

 if (ViewModelBase.IsInDesignModeStatic) { SimpleIoc.Default.Register<IDataService, Design.DesignDataService>(); } else { //SimpleIoc.Default.Register<IDataService, Design.DesignDataService>(); SimpleIoc.Default.Register<IDataService, DataService>(); }

In the Design class I've decided to create an XML file for each Model so that it's easy to change the sample data and test all possible scenarios.

I then use the Deserialize function to read it:

 csNodeList _Copyrights = new csNodeList(); resource = System.Windows.Application.GetResourceStream(new Uri(@"Design/sampledata.xml", UriKind.Relative)); streamReader = new StreamReader(resource.Stream); serializer = new XmlSerializer(typeof(csNodeList)); _Copyrights = (csNodeList)serializer.Deserialize(streamReader);

17487809 0 Sort table by reputation and select rank + LIMIT to print above and below rows

I am trying to sort the table by the reputation and then select the position of the row [rank], it works fine, but I would like to print out 3 tables above and 3 tables below this rank row, but LIMIT rank,6 does not work :/ (Im sorry for that wrong formatted SQL :/) Would be thankful for every help :)

Here is what is working:

$query = mysqli_query($con, "SET @rank=0"); $query = mysqli_query($con, " SELECT rank, user_email, reputation FROM ( SELECT @rank:=@rank+1 AS rank, user_email, reputation FROM accounts, (SELECT @rank := 0) r ORDER BY reputation DESC LIMIT 0,7 ) t WHERE reputation >= '5' OR reputation < '5'");

prints

[rank] [user_email] [reputation] 1 mail1@gmail.com 20 2 test@test.com 15 3 mail2@gmail.com 10 4 othermail@gmail.com 5 5 hmmmmm@gmail.com 0 6 ouch@gmail.com 0 7 somemail@gmail.com 0

18802773 0 Android doesn't deliver correct PHOTO_URI

I am using a QuickContactBadge. Now I get this messages on a Sony Xperia P. I developed the app on CyanogenMod and eveything was fine.

Unable to open content: content://com.android.contacts/contacts/939/photo java.io.FileNotFoundException: content://com.android.contacts/contacts/939/photo

This is my code:

projection = new String[] { ContactsContract.CommonDataKinds.Phone._ID, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.PHOTO_URI }; contactCursor = getContentResolver().query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, projection, null, null, null); ... thumbnail = contactCursor.getString(contactCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI)); ... quickContactBadge.setImageURI(Uri.parse(ThumbnailString));

My suggestion was that the Sony ROM doesn't deliver an valid PHOTO_URI but it looks legit.

The unique event count for an action is the number of visits in which that action took place.

The total unique events in this report should equal the sum of unique events on all rows, not the number of rows. This is because a unique event is based on unique action-visit combinations, and each row has a different action.

In other words, if an action is repeated within a visit, the unique event count is not incremented, but otherwise it is.

So if one of the rows has 2 unique events that would mean that the event action was triggered in 2 separate visits, and both these visits would be included in the overall unique events.

In your example, the first 10 actions in your report only occurred for 1 visit each (they may even have all been the same visit - you can't tell from this report).

So I'm guessing that on the second page of your example there are two rows with 0 unique events, and the rest have 1 unique event - so that they add up to 21 unique events.

Yes, you can do this, but it needs to be done through a separate mechanism than the c argument. In a nutshell, use facecolors=rgb_array.

First off, let me explain what's going on. The Collection that scatter returns has two "systems" (for lack of a better term) for setting colors.

If you use the c argument, you're setting the colors through the ScalarMappable "system". This specifies that the colors should be controlled by applying a colormap to a single variable. (This is the set_array method of anything that inherits from ScalarMappable.)

In addition to the ScalarMappable system, the colors of a collection can be set independently. In that case, you'd use the facecolors kwarg.

As a quick example, these points will have randomly specified rgb colors:

import matplotlib.pyplot as plt import numpy as np x, y = np.random.random((2, 10)) rgb = np.random.random((10, 3)) fig, ax = plt.subplots() ax.scatter(x, y, s=200, facecolors=rgb) plt.show()

26389463 0 Customize table with jquery

I want to design a customize table layout. For example after adding data my table is created. Now I am showing column name in one column and column data in another column, I want to add functionality if I drag one row to third column, Then column structure will be modified and that row will be added to new column.

For example: This is my table: jsfiddle.net/x8L57md2/

code:-

 <tr> <td>Name</td> <td> Ankur </td> </tr> <tr> <td>Address</td> <td>jaipur</td> </tr> <tr> <td>State</td> <td> Rajasthan</td> </tr> <tr> <td>Country</td> <td>India</td> </tr> <table>

If I move state column to right side of ankur(name) then another table column will be created and append it to table with data.

Like this: jsfiddle.net/ttzr2ezh/

code:-

 <table border="1"> <tr> <td>Name</td> <td> Ankur </td> <td>State</td> <td> Rajasthan</td> </tr> <tr> <td>Address</td> <td>jaipur</td> </tr> <tr> <td>Country</td> <td>India</td> </tr> <table>

8892831 1 How to emulate os.path.samefile behaviour on Windows and Python 2.7?

Given two paths I have to compare if they're pointing to the same file or not. In Unix this can be done with os.path.samefile, but as documentation states it's not available in Windows. What's the best way to emulate this function? It doesn't need to emulate common case. In my case there are the following simplifications:

Paths don't contain symbolic links.
Files are in the same local disk.

Now I use the following:

def samefile(path1, path2) return os.path.normcase(os.path.normpath(path1)) == \ os.path.normcase(os.path.normpath(path2))

Is this OK?

My company is using Amazon EC2 now and I am down at the PDC watching the details on Azure unfold. I have not seen anything yet that would convince us to move away from Amazon. Azure definitely looks compelling, but the fact is I can now utilize Windows and SQL server on Amazon with SLAs in place. Ray Ozzie made it clear that Azure will be changing A LOT based on feedback from the developer community. However, Azure has a lot of potential and we'll be watching it closely.

Also, Amazon will be adding load balancing, autoscaling and dashboard features in upcoming updates to the service (see this link: http://aws.amazon.com/contact-us/new-features-for-amazon-ec2/). Never underestimate Amazon as they have a good headstart on Cloud Computing and a big user base helping refine their offerings already. Never underestimate Microsoft either as they have a massive developer community and global reach.

Overall I do not think the cloud services of one company are mutually exclusive from one another. The great thing is that we can leverage all of them if we want to.

Microsoft should offer up the ability to host Linux based servers in their cloud. That would really turn the world upside down!

22946850 0 Evolutionary Artificial Intelligence in Video Games

I had an idea pertaining to the use of Artificial Intelligence on a larger scale then most games. The idea is to train and score agents in a game against players, then the data is sent back to a server where it can be scored for fitness and then added to the pool for evolutionary selection. At that point the new agents would be redistributed to the players to be trained and scored by the players again.

I am thinking this would be a good use for possibly a neural network or finite state machine that is evolved in a co-evolutionary manner (AI = predator, Players = prey). What I want to know is:

1) Are there any papers or examples of this happening already in games? I haven't been able to find any examples.

2) Does it seem like this approach would be any better then the traditional approach to AI in games?

I am working on a Tactical Turn-based Strategy and thought that this could add a new dimension to gameplay if I can pull it off.

For a working doodle/proof of concept of an approach to utilize pure JavaScript along with the familiar and declarative pattern behind XSLT's matching expressions and recursive templates, see https://gist.github.com/brettz9/0e661b3093764f496e36

(A similar approach might be taken for JSON.)

Note that the demo also relies on JavaScript 1.8 expression closures for convenience in expressing templates in Firefox (at least until the ES6 short form for methods may be implemented).

getText() is returning null, so you're writing "null" down to the server. At least, that's what I found after changing your just enough to get it to compile and run.

After changing getText() to return "hello" I got:

Server:

Server is starting... Server is listening... Client Connected...

Client:

java.io.BufferedReader@7d2152e6 Text received: hello

(The "BufferedReader@7d..." line is due to System.out.println(is);)

Note that after the client has disconnected, your server is going to keep trying to send "null" back to it, because you don't test for line being null in the server code.

When you require 'something' Ruby searches for a file called either something.rb or something.dll/so/bundle depending on your platform.

In case it finds a library dll/so/bundle it dynamically loads it and search for a symbol called Init_something. The convention when creating a native extension is to include such a function which gets used by the ruby interpreter to hook things up.

Where (in which directories) the intrepeter looks for rb files and libs is determined by the load path, which you can append using the -I options of the interpreter. At runtime, the current load path is in $: (you can append further directories to this at runtime as well), for example:

$ irb irb(main):001:0> puts $: /opt/local/lib/ruby/site_ruby/1.8 /opt/local/lib/ruby/site_ruby/1.8/i686-darwin9 /opt/local/lib/ruby/site_ruby /opt/local/lib/ruby/vendor_ruby/1.8 /opt/local/lib/ruby/vendor_ruby/1.8/i686-darwin9 /opt/local/lib/ruby/vendor_ruby /opt/local/lib/ruby/1.8 /opt/local/lib/ruby/1.8/i686-darwin9 .

have a look at the documentation of require (http://ruby-doc.org/core-1.8.7/classes/Kernel.html#M001077)

I'm not sure what you mean by:

P.S. The only exposed part of Ruby I have to work with right now is 'msvcrt-ruby18.dll'

Also you mentioned something about sandboxing. This may interfere with your ability to require modules. Search for $SAFE, if $SAFE is set to >2 you won't be able to use require at all.

If your interests are machine learning, data mining and computer vision then I'd say a Lego mindstorms is not the best option for you. Not unless you are also interested in robotics/electronics.

Do do interesting machine learning you only need a computer and a problem to solve. Think ai-contest or mlcomp or similar.
Do do interesting data mining you need a computer, a lot of data and a question to answer. If you have an internet connection the amount of data you can get at is only limited by your bandwidth. Think netflix prize, try your hand at collecting and interpreting data from wherever. If you are learning, this is a nice place to start.
As for computer vision: All you need is a computer and images. Depending on the type of problem you find interesting you could do some processing of random webcam images, take all you holiday photo's and try to detect where all your travel companions are in them. If you have a webcam your options are endless.

Lego mindstorms allows you to combine machine learning and computer vision. I'm not sure where the datamining would come in, and you will spend (waste?) time on the robotics/electronics side of things, which you don't list as one of your passions.

This is a great use case for either by or lapply rather than a for-loop. Basically, the result is the same, but without the overhead of writing a loop, iterating over it, and storing the results appropriate. Here's a simple example like yours that uses the built-in mtcars dataset:

b <- by(mtcars, mtcars$gear, FUN = function(d) xtabs(~cyl + vs + am, data = d)) l <- lapply(split(mtcars, mtcars$gear), FUN = function(d) xtabs(~cyl + vs + am, data = d))

We can use str to take a look at what we created:

> str(b, 1) List of 3 $ 3: xtabs [1:3, 1:2, 1] 0 0 12 1 2 0 ..- attr(*, "dimnames")=List of 3 ..- attr(*, "class")= chr [1:2] "xtabs" "table" ..- attr(*, "call")= language xtabs(formula = ~cyl + vs + am, data = d) $ 4: xtabs [1:2, 1:2, 1:2] 0 0 2 2 0 2 6 0 ..- attr(*, "dimnames")=List of 3 ..- attr(*, "class")= chr [1:2] "xtabs" "table" ..- attr(*, "call")= language xtabs(formula = ~cyl + vs + am, data = d) $ 5: xtabs [1:3, 1:2, 1] 1 1 2 1 0 0 ..- attr(*, "dimnames")=List of 3 ..- attr(*, "class")= chr [1:2] "xtabs" "table" ..- attr(*, "call")= language xtabs(formula = ~cyl + vs + am, data = d) - attr(*, "dim")= int 3 - attr(*, "dimnames")=List of 1 - attr(*, "call")= language by.data.frame(data = mtcars, INDICES = mtcars$gear, FUN = function(d) xtabs(~cyl + vs + am, data = d)) - attr(*, "class")= chr "by" > str(l, 1) List of 3 $ 3: xtabs [1:3, 1:2, 1] 0 0 12 1 2 0 ..- attr(*, "dimnames")=List of 3 ..- attr(*, "class")= chr [1:2] "xtabs" "table" ..- attr(*, "call")= language xtabs(formula = ~cyl + vs + am, data = d) $ 4: xtabs [1:2, 1:2, 1:2] 0 0 2 2 0 2 6 0 ..- attr(*, "dimnames")=List of 3 ..- attr(*, "class")= chr [1:2] "xtabs" "table" ..- attr(*, "call")= language xtabs(formula = ~cyl + vs + am, data = d) $ 5: xtabs [1:3, 1:2, 1] 1 1 2 1 0 0 ..- attr(*, "dimnames")=List of 3 ..- attr(*, "class")= chr [1:2] "xtabs" "table" ..- attr(*, "call")= language xtabs(formula = ~cyl + vs + am, data = d)

In this case, I think the result from lapply is probably closer to what you're going for, but (as you can hopefully see) the structures are very similar - both are lists of xtabs objects.

Your code is somewhat confusing. Is MyTabBarController the class? It looks like mainTabVC is your instance. You should use that rather than the class, and you should change the type when you instantiate mainTabVC to MyTabBarController, instead of UITabBarController. You also don't need to get the storyboard the way you do, you can just use self.storyboard.

 MyTabBarController *mainTabVC = [self.storyboard instantiateViewControllerWithIdentifier:@"mainTabVC"]; mainTabVC.managedObjectContext = self.managedObjectContext; [mainTabVC setModalPresentationStyle:UIModalPresentationFullScreen]; [self presentViewController:mainTabVC animated:NO completion:nil];

22159190 0

We solved this 10 minute timeout problem by implementing a small amount of Javascript which every 9 minutes sends an ajax request to a URL which sends back a new blob upload URL and swaps out the form.

The /ajax/blob URL takes a success url, and then calls create_upload_url() and returns it as an ajax data object.

Here's the Javascript we wrote:

if ($('#blobUploadForm').length > 0) { setTimeout(_getNewBlobstoreUrl, 9 * 1000 * 60 * 60); // 9 minutes } //do nothing if there is no uploadUrl id function _getNewBlobstoreUrl() { var successUrl = $('#uploadUrl').attr('value'); if (typeof successUrl == 'undefined') { return; } var url = "/ajax/blob?url=" + successUrl; $.ajax({ url: url, dataType: "json", cache: false, async: true, success: _getNewBlobstoreUrlSuccess, error: _getNewBlobstoreUrlError }) function _getNewBlobstoreUrlSuccess(data) { if (data.url) { //change the action to a new action $('#blobUploadForm').attr('action', data.url) } } function _getNewBlobstoreUrlError(err) { // do something }

Don't forget at the end to setup the timeout again too (or use setInterval?), in case the user takes a really long time to fill in the form.

You probably want to create two functions in R:

getdata: a function that retrieves the data from your database, and returns the data frame.
makeplot : a function with a dataframe argument that creates your plot and returns nothing.

Then your client you can call them separately. First the client calls getdata to retrieve the data from the db, and the server will respond with a temporary {key} that represents the returned dataframe object on the server, for example x01234567.

Then you can use this key to either download the dataset or use it as an argument to create the plot. To download the data, simply create a hyperlink to for example:

http://your.server.com/ocpu/tmp/x01234567/R/.val/csv
http://your.server.com/ocpu/tmp/x01234567/R/.val/tab
http://your.server.com/ocpu/tmp/x01234567/R/.val/json

To create the plot, the client calls makeplot and passes x01234567 as the argument value for the data frame. The OpenCPU server will automatically lookup the object for this key to the dataframe object that was returned before by getdata.

The easiest way to do this, is to get the StyledDocument from the JTextPane, and to use the setCharacterAttributes() method.

The setCharacterAttributes method on the StyledDocument object allows you to set for a specific character range, a set of attributes, which can include BOLD.

See the Javadoc for more info

Some sample code could be

// set chars 4 to 10 to Bold SimpleAttributeSet sas = new SimpleAttributeSet(); StyleConstants.setBold(sas, true); textPane.getStyledDocument().setCharacterAttributes(4, 6, sas, false);

You can't access data asset files in the same way you access a random file using NSBundle.pathForResource. Since they can only be defined within Assets.xcassets, you need to initialize a NSDataAsset instance in order to access the contents of it:

let asset = NSDataAsset(name: "Colors", bundle: NSBundle.mainBundle()) let json = try? NSJSONSerialization.JSONObjectWithData(asset!.data, options: NSJSONReadingOptions.AllowFragments) print(json)

Please note that NSDataAsset class was introduced as of iOS 9.0 & macOS 10.11.

Swift3 version:

let asset = NSDataAsset(name: "Colors", bundle: Bundle.main) let json = try? JSONSerialization.jsonObject(with: asset!.data, options: JSONSerialization.ReadingOptions.allowFragments) print(json)

Also, NSDataAsset is surprisingly located in UIKit/AppKit so don't forget to import the relevant framework in your code:

#if os(iOS) import UIKit #elseif os(OSX) import AppKit #endif

If you assign this reference to a member variable, you have a recursion. Yes, it doesn't matter how many s's you'll add, because they are always the same object, which is this object. It's the same as if you wrote:

this.this.this.this.this.this.x++;

Function f() returns reference to this object after doing some other operations on it. It's a common design pattern in Java, called builder. Adding ability to do a4.f().g(); to a class is called method chaining. In other words, f() is this object at the end of the call, just like s is, so you can do:

a1.f().f().f().f().f().f();

And it means you just called f() function from a1 object 6 times.

You're getting an exception from the DirectoryInfo object, so you need to use try / catch:

function Get-HugeDirStats ($directory) { function go($dir, $stats) { try { foreach ($f in $dir.GetFiles()) { $stats.Count++ $stats.Size += $f.Length } foreach ($d in $dir.GetDirectories()) { go $d $stats } } catch [Exception] { # Do something here if you need to } } $statistics = New-Object PsObject -Property @{Count = 0; Size = [long]0 } go (new-object IO.DirectoryInfo $directory) $statistics $statistics }

If you're getting errors from any powershell cmdlets, you can use -ErrorAction SilentlyContinue on the cmdlet to prevent errors printing to the screen.

Your best bet is probably SQLite, a database engine. From Apple's iOS Data Management page:

iOS includes the popular SQLite library, a lightweight yet powerful relational database engine that is easily embedded into an application. Used in countless applications across many platforms, SQLite is considered a de facto industry standard for lightweight embedded SQL database programming. Unlike the object-oriented Core Data framework, SQLite uses a procedural, SQL-focused API to manipulate the data tables directly.

In my research about rolling back transactions in EF4, it seems everybody refers to this blog post or offers a similar explanation. In my scenario, I'm wanting to do this in a unit testing scenario where I want to rollback practically everything I do within my unit testing context to keep from updating the data in the database (yeah, we'll increment counters but that's okay). In order to do this, is it best to follow the following plan? Am I missing some concept or anything else major with this (aside from my SetupMyTest and PerformMyTest functions won't really exist that way)?

[TestMethod] public void Foo { using (var ts = new TransactionScope()) { // Arrange SetupMyTest(context); // Act PerformMyTest(context); var numberOfChanges = context.SaveChanges(SaveOptions.AcceptAllChangesAfterSave); // if there's an issue, chances are that an exception has been thrown by now. // Assert Assert.IsTrue(numberOfChanges > 0, "Failed to _____"); // transaction will rollback because we do not ever call Complete on it } }

40528566 1 How to aggregate values over a bigger than RAM gzip'ed csv file?

For starters I am new to bioinformatics and especially to programming, but I have built a script that will go through a so-called VCF file (only the individuals are included, one clumn = one individual), and uses a search string to find out for every variant (line) whether the individual is homozygous or heterozygous.

This script works, at least on small subsets, but I know it stores everything in memory. I would like to do this on very large zipped files (of even whole genomes), but I do not know how to transform this script into a script that does everything line by line (because I want to count through whole columns I just do not see how to solve that).

So the output is 5 things per individual (total variants, number homozygote, number heterozygote, and proportions of homo- and heterozygotes). See the code below:

#!usr/bin/env python import re import gzip subset_cols = 'subset_cols_chr18.vcf.gz' #nuc_div = 'nuc_div_chr18.txt' gz_infile = gzip.GzipFile(subset_cols, "r") #gz_outfile = gzip.GzipFile(nuc_div, "w") # make a dictionary of the header line for easy retrieval of elements later on headers = gz_infile.readline().rstrip().split('\t') print headers column_dict = {} for header in headers: column_dict[header] = [] for line in gz_infile: columns = line.rstrip().split('\t') for i in range(len(columns)): c_header=headers[i] column_dict[c_header].append(columns[i]) #print column_dict for key in column_dict: number_homozygotes = 0 number_heterozygotes = 0 for values in column_dict[key]: SearchStr = '(\d)/(\d):\d+,\d+:\d+:\d+:\d+,\d+,\d+' #this search string contains the regexp (this regexp was tested) Result = re.search(SearchStr,values) if Result: #here, it will skip the missing genoytypes ./. variant_one = int(Result.group(1)) variant_two = int(Result.group(2)) if variant_one == 0 and variant_two == 0: continue elif variant_one == variant_two: #count +1 in case variant one and two are equal (so 0/0, 1/1, etc.) number_homozygotes += 1 elif variant_one != variant_two: #count +1 in case variant one is not equal to variant two (so 1/0, 0/1, etc.) number_heterozygotes += 1 print "%s homozygotes %s" % (number_homozygotes, key) print "%s heterozygotes %s" % (number_heterozygotes,key) variants = number_homozygotes + number_heterozygotes print "%s variants" % variants prop_homozygotes = (1.0*number_homozygotes/variants)*100 prop_heterozygotes = (1.0*number_heterozygotes/variants)*100 print "%s %% homozygous %s" % (prop_homozygotes, key) print "%s %% heterozygous %s" % (prop_heterozygotes, key)

Any help will be much appreciated so I can go on investigating large datasets, thank you :)

The VCF file by the way looks something like this: INDIVIDUAL_1 INDIVIDUAL_2 INDIVIDUAL_3 0/0:9,0:9:24:0,24,221 1/0:5,4:9:25:25,0,26 1/1:0,13:13:33:347,33,0

This is then the header line with the individual ID names (I have in total 33 individuals with more complicated ID tags, I simplified here) and then I have a lot of these information lines with the same specific pattern. I am only interested in the first part with the slash so hence the regular epxression.

37334888 0 Reduce Transparency setting in OS X makes white text in NSButton in popover disappear

I'm working on an OS X app that involves popovers with web views in them. The web views have drawsBackground set to NO. Sometimes there are buttons in these popovers, on top of the web views. These buttons have custom background colors and have their text colors set via NSAttributedString. But when the Reduce Transparency setting is on in System Preferences, the white text disappears. If the text is any other color, it shows up - even clear (though faintly).

See here for an example project on GitHub demonstrating the problem.

What is going on here?

Update: I talked to an engineer at WWDC 2016 about this, and he confirmed it was a bug. I filed a radar. He did manage to fix it in my code by setting the appearance of the button in question to NSAppearanceNameAqua.

For detecting CTRL + F:

event.ctrlKey == true && event.keyCode == Keyboard.F

where 'event' is of course a KeyBoardEvent.

As for the F3 question: the code you wrote will work as long as the flash application has focus. The F3 key command will then also not be routed to the browser. So what you need to do, is make sure that your application has focus when the user hits F3. How you solve this will depend on your JavaScript implementation. You could use ExternalInterface to tell the browser that the app is ready and than focus on the app. Or in Javascript you could catch the keyboard event, prevent its default behavior, and then call the function on the Flash app (again through ExternalInterface).

To get you started, here's a little JQuery snippet for preventing the default F3 behaviour:

$('body').keyup(function(event) { if (event.keyCode == '114') event.preventDefault(); }

Calling object methods internally in dojo

After reading what you have posted, I have somehow understood the answer linked above and now understand what my problem was! Thanks to all.

I fixed it by altering my code in the main application as follows:

var appInterface = new Interface(); on(registry.byId("graphBtn"),"click", appInterface.toggleGraphWindow);

changed to:

var appInterface = new Interface(); var graphToggle = dojo.hitch(appInterface, "toggleGraphWindow"); on(registry.byId("graphBtn"),"click", graphToggle);

I believe the reason for the error, was that the "this" object at runtime, was actually the "graphBtn" instead of the appInterface.

What you are referring in Java is called anonymous inner class - you are actually declaring a one-time derived class inline.

Unfortunately Swift doesn't have this feature.

But you can consider passing a closure to the instance.

Lets say that your Card class have a var getCardFunction:

Class Card { var getCardFunction : () -> Int }

Now you can pass the function you desire after initialising:

var card = Card() card.getCardFunction = { return 6 }

Note: you can even have a default value for the getCardFunction function:

Class Card { var getCardFunction : () -> Int = { return 3 } }

So, the choices are, to switch to VS2012, for which there is a Plug-In, or invest in figuring out the format in VS2010 and fixing the existing suggested code.

Or, and that's what I did, use std::tr1::unordered_set / map instead. There is a visualizer for it in Visual Studio. And, later on, after debugging, if you wish, switch back to boost.

You need to retain a copy of the AdMob AdViewController as Admob no longer does this itself.

In your viewcontroller.h add something like

IBOutlet AdViewController *localAdViewController;

inside the @interface section, and add

@property (nonatomic, retain) AdViewController *localAdViewController;

afterwards.

Then add a link in IB from File's owner to your localAdViewController in AdViewController.

Should work fine then on.

When I checked logs carefully I noticed Server is sending only first certificate in chain of certificates to client i.e,. ( CN=Unknown, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=Unknown ), my newly created certificate is not present. Am I doing something wrong?

Hum... Norwegian is included in UTF8.

You surely have an encoding problem. It's strange, i never face that with localisables...

However, becareful, you have a syntax error in your english localisable : you must finish every line with ;

"of"="of";

You need to make sure all of your assemblies are compiling for the correct architecture. Try changing the architecture for x86 if reinstalling the COM component doesn't work.

17660504 0 GXT get value of TextArea without focus loss

I have a GXT 3 TextArea on which I catch copy-paste events. On this event, I would like to get the text that is inside the textarea.

Problem : the textarea still has the focus so the value is not updated. Hence, getValue() returns an empty string...

I tried to call getValue() getCurrentValue() flush() validate().

I also tried to extend TextArea to have access to blur() method and call it before getting the value : it makes no difference.

Any solution? (even solution with GWT components would be appreciated).

The API and all client libraries in turn will return actual objects when they are queried for. However, when referencing an object in the API you do so with just the object's ID.

Therefore, in your code above, workspace holds the actual workspace object. In order to use that in a query you must use workspace: workspace.id.

You can see a working example of .find_by_workspace() here:

puts "My Workspaces:" client.workspaces.find_all.each do |workspace| puts "\t* #{workspace.name} - tags:" client.tags.find_by_workspace(workspace: workspace.id).each do |tag| puts "\t\t- #{tag.name}" end end

Threads do not work, abstain from that approach.

Creating several threads fails, as you have noticed, because only one thread has a current OpenGL context. In principle, you could make the context current in each worker thread before calling glReadPixels, but this will require extra synchronization from your side (otherwise, a thread could be preempted in between making the context current and reading back!), and (wgl|glx)MakeCurrent is a terribly slow function that will seriously stall OpenGL. In the end, you'll be doing more work to get something much slower.

There is no way to make glReadPixels any faster¹, but you can decouple the time it takes (i.e. the readback runs asynchronously), so it does not block your application and effectively appears to run "faster".
You want to use a Pixel buffer object for that. Be sure to get the buffer flags correct.

Note that mapping the buffer to access its contents will still block if the complete contents hasn't finished transferring, so it will still not be any faster. To account for that, you either have to read the previous frame, or use a fence object which you can query to be sure that it's done.
Or, simpler but less reliable, you can insert "some other work" in between glReadPixels and accessing the data. This will not guarantee that the transfer has finished by the time you access the data, so it may still block. However, it may just work, and it will likely block for a shorter time (thus run "faster").

¹ There are plenty of ways of making it slower, e.g. if you ask OpenGL to do some weird conversions or if you use wrong buffer flags. However, generally, there's no way to make it faster since its speed depends on all previous draw commands having finished before the transfer can even start, and the data being transferred over the PCIe bus (which has a fixed time overhead plus a finite bandwidth).
The only viable way of making readbacks "faster" is hiding this latency. It's of course still not faster, but you don't get to feel it.

31219272 0 Selector in Method over riding

In the case of method over riding in objective c how selector knows that which method needs to call via selector?

As we dont pass any arguments in slector section...

Ex: in tmp.m file There is 2 methods with different arguments

-(void)details { } -(void)details:(NSDictionary *)result { }

And when m call another method with the use of selector as:

[mc detailstrac:[[NSUserDefaults standardUserDefaults] valueForKey:@"userID"] tracid:self.trac_id selector:@selector(details:)];

How selector knows to call which method !

I have checked that

-(void)details:(NSDictionary *)result { }

this method is called every time then what about

-(void)details { }

this ?

You can't: floating point numbers aren't exact values, only estimations, by definition. You are supposed to get such deviations.

30950216 1 Unit testing Python Flask Stream

Does anybody have any experience/pointers on testing a Flask Content Streaming resource? My application uses Redis Pub/Sub, when receiving a message in a channel it streams the text 'data: {"value":42}' The implementation is following Flask docs at: docs and my unit tests are done following Flask docs too. The messages to Redis pub/sub are sent by a second resource (POST).

I'm creating a thread to listen to the stream while I POST on the main application to the resource that publishes to Redis.

Although the connection assertions pass (I receive OK 200 and a mimetype 'text/event-stream') the data object is empty.

My unit test is like this:

def test_04_receiving_events(self): headers = [('Content-Type', 'application/json')] data = json.dumps({"value": 42}) headers.append(('Content-Length', len(data))) def get_stream(): rv_stream = self.app.get('stream/data') rv_stream_object = json.loads(rv_stream.data) #error (empty) self.assertEqual(rv_stream.status_code, 200) self.assertEqual(rv_stream.mimetype, 'text/event-stream') self.assertEqual(rv_stream_object, "data: {'value': 42}") t.stop() threads = [] t = Thread(target=get_stream) threads.append(t) t.start() time.sleep(1) rv_post = self.app.post('/sensor', headers=headers, data=data) threads_done = False while not threads_done: threads_done = True for t in threads: if t.is_alive(): threads_done = False time.sleep(1)

The app resource is:

@app.route('/stream/data') def stream(): def generate(): pubsub = db.pubsub() pubsub.subscribe('interesting') for event in pubsub.listen(): if event['type'] == 'message': yield 'data: {"value":%s}\n\n' % event['data'] return Response(stream_with_context(generate()), direct_passthrough=True, mimetype='text/event-stream')

Any pointers or examples of how to test a Content Stream in Flask? Google seems to not help much on this one, unless I'm searching the wrong keywords.

Thanks in advance.

HasColumnType("datetime") specifies the column type, not the temporary parameter types that are used in the SQL statements. You can't control those and it's not necessary. If you have a .NET DateTime in your application with some decimal places filled and want to store that in a datetime type in SQL Server the value will (and can only) be stored as a rounded value. It doesn't matter if the rounding happens on client side before the SQL is sent to the database server or if the rounding happens on the database server itself. The result will be the same: A rounded stored value with a loss of precision.

I recommend the following:

require 'yaml' data = YAML.load_file '<filename>' data.sort_by{|hash| hash[:key1]}

Your file looks quite a bit like JSON data, but includes a few minor formatting differences that make using a JSON parser impossible. Thankfully the data is perfectly valid YAML, so Ruby's YAML parser can read it just fine.

Relations are defined by predicates in Prolog. There is no built-in (but you could do it for example by using term expansion) syntactic way to define predicates inside predicates in program text, and there seems little reason to do so. You can simply write separate predicates and refer to them. You can of course have nested terms, that is terms as subterms of other terms.

What do you mean with

relation(CctypeInt,[0-{2,3,4}, 1-{2,3,4}, 2-{2}],Ru1),!.

? This is a clause that states something about the predicate (,)/2 , which I doubt was the intention. On the other hand, you can of course build and use a Prolog term like

relation(cctypeint,relation(ru_1,...,ru_n))

in your programs to represent your data.

19327731 0 How to find the vertical and horizontal distance from the center of a rectangle

For my current Java project I have to compute the horizontal and vertical distance from the center of a rectangle. I tried using the formula from a previous project to find such a distance. Here is my code:

 // Calculations; centerCoordinate = 0 formula = Math.sqrt(Math.pow(userXCoordinate - centerCoordinate, 2) + Math.pow(userYCoordinate - centerCoordinate, 2));

My professor gave the hint that a point is in the rectangle if its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its vertical distance to (0, 0) is less than or equal to 5 / 2. I tried using 5 for horizontal distance and 2.5 for vertical distance and setting variables to these numbers. I then made an if-else loop saying if the result of the formula was less than or equal to the variables the coordinates were in the rectangle otherwise they were outside. This returned a wrong answer; what could I do differently?

Chrome (or any other browser) doesn't support HTAs at all. Actually HTAs are run by mshta.exe, and IE is used as a rendering & scripting engine.

When HTA is run with IE9 (<meta http-equiv="x-ua-compatible" content="IE=9">) there are some issues with <HTA: application>, like some mess with icon and window borders.

With IE10 (<meta http-equiv="x-ua-compatible" content="IE=edge">) it seems, that HTA properties are ignored totally, even singleInstance="yes" doesn't work. If you take a look at a runtime source, you can see the <HTA: application> tag is moved to the body, where it has not the expected influence.

All above written about IE is related to the actual HTA properties only, all HTML, scripts and privilegs work well. With IE10 even better and faster than ever before, and you can use real JavaScript instead of JScript.

To utilize all available features, you need to add document type and x-ua-compatible to your pages:

<!DOCTYPE html> <html> <head> <title></title> <meta http-equiv="x-ua-compatible" content="IE=edge"> ...

4346901 0 Suggestion for solving fragile pattern matching

I often need to match a tuple of values that should have the same constructor. The catchall _,_ always winds-up at the end. This of course is fragile, any additional constructor added to the type will compile perfectly fine. My current thoughts are to have matches that connect the first but not second argument. But, is there any other options?

For example,

type data = | States of int array | Chars of (char list) array let median a b = match a,b with | States xs, States ys -> assert( (Array.length xs) = (Array.length ys) ); States (Array.init (Array.length xs) (fun i -> xs.(i) lor ys.(i))) | Chars xs, Chars ys -> assert( (Array.length xs) = (Array.length ys) ); let union c1 c2 = (List.filter (fun x -> not (List.mem x c2)) c1) @ c2 in Chars (Array.init (Array.length xs) (fun i -> union xs.(i) ys.(i))) (* inconsistent pairs of matching *) | Chars _, _ | States _, _ -> assert false

The second argument to search-forward bounds the search, so to search for a string on the current line, go to the start of the line, and use the end of the line as your bound:

(beginning-of-line) (search-forward myword (line-end-position))

If you don't want to move point, then use save-excursion to preserve it:

(save-excursion (beginning-of-line) (search-forward myword (line-end-position)))

Use the replace method:

function cap(str) { return str.replace(/([a-z])/, function (match, value) { return value.toUpperCase(); }) }

DEMO

Edit: In case you have a string containing multiple (space-separated) words, try something like:

function cap(str) { return str.split(' ').map(function (e) { return e.replace(/([a-z])/, function (match, value) { return value.toUpperCase(); }) }).join(' '); }

This would convert "50newyork paris84 london" to "50Newyork Paris84 London"

JSF 2.0 has offered Bean Validation (JSR 303) and its own Validation framework, given the choices, i am confused with which one to choose from.

It seems that with JSF's validation framework, i may specify constraints at the XHTML view layer. i.e. max length. While using Bean Validation, i would specify the constraints via annotations (@) in the bean.

I see the JSF Validation framework as more of a plug-gable attempt, while the bean validation JSR as an elegant solution, can anyone comment on this?

May i check if anyone has used one over another and why, or if anyone has used both together?

2) Created the S3 Bucket. And I load the object into it as: Hive Script, File to load into the table.

3) Then Created the Job Flow (Using Sample Hive Program). Given the input, ouput, and script path (like s3n://bucketname/script.q, s3n://bucketname/input.txt, s3n://bucketname/out/). Didn't create out directory. I think it will get created automatically.

4) Then Job Flow start to run and after some time I saw the states as STARTING, BOOTSTRAPING, RUNNING, and SHUT DOWN.

5) While running SHUT DOWN state, it get terminated automatically showing FAILES status for SHUT DOWN.

Then on the S3, I didn't see the out directory. How to see the output? I saw directory like daemons, nodes, etc......

And also how to see the data from HDFS in Amazon EMR?

19045469 0 javascript: null variable in function changes its value?

Can a null variable in a function become not null? When f enters in function chainF it somehow changes its value? It isn't null anymore.

function TestF(){} TestF.prototype = { i: 0, f: null, chainF: function(g){ if(this.f == null) console.log('f is null'); var newF = function(){ if(this.f == null) console.log('f is null'); g(); }; this.f = newF; return this; } } t = new TestF(); t.chainF(function(){console.log('g')}).f();

Output: f is null (only once) g

There might be other problems in your snippet, so far I've noticed you're using std::map which is unusual data-structure for this purpose as std::map will overwrite previous nodeId with same weight. You can use std::multimap but you will need some more std::iterator and stuffs for looping on key-value pairs. Use std::priority_queue which will allow you to keep the code precise.

Here is a simple snippet solution with std::priority_queue which calculate shortest distance from source to destination node. You can modify or write similarly for your problems:

#define Max 20010 // MAX is the maximum nodeID possible vector <pair<int, int>> adj[Max]; // adj[u] contains the adjacent nodes of node u int dis[Max]; // dis[i] is the distance from source to node i priority_queue <pair<int, int>, vector<pair<int, int> >, greater<pair<int, int> > > Q; int dijkstra(int src, int des) { memset(dis, MAX, sizeof dis); Q = priority_queue <pair<int, int>, vector<pair<int, int> >, greater<pair<int, int> > > (); dis[src] = 0; Q.push({dis[src] , src}); while(!Q.empty()) { int u = Q.top().second; Q.pop(); if(u == des) { return dis[des]; } for(int i = 0; i < (int)adj[u].size(); ++i) { int v = adj[u][i].first; int cost = adj[u][i].second; if(dis[v] > dis[u] + cost) { dis[v] = dis[u] + cost; Q.push({dis[v], v)}); } } } return -1; // no path found }

Your function is not "returning" anything. It prints a value to stdout, and each invocation will do that.

If you want to simulate a function return with this mechanism, you need to capture and resend the value:

Bash functions return an exit status, and this works as you might expect (as long as you expect 0 to be success). If you don't specify otherwise, the return value is that of the last command. So the following would work:

tryn() { if (($1 == 0)); then return 2; fi "$@" || tryn $(($1-1)) "$@" } if tryn 2 ping $host; then # success fi

Doing it the way you describe will not do any harm.
You can move the .git directory into the tree you want to commit instead of moving the tree to the repository.
You can use the --work-tree option or GIT_WORK_TREE environment variable to act as if you did that:
```
git add --work-tree=CurrentProduction -A; git commit ... 
```
Note that it is not necessary to specify it for commands after add since add copies content into the index, commit uses the index, and the index is in .git.

As a separate issue, note that your procedure will make the develop initial commit a child of the master initial commit. That is probably the right thing for this case; I just want to make sure you're aware it's not symmetric.

5430663 0 Adding observer to NSNotificationCenter second time causes EXC_BAD_ACCESS

Hypothetical scenario:

In my viewDidLoad method I am adding view controller as an observer for custom notification (say, notification MyFooNotification). Later in the process when view is loaded the notification gets posted and controller processes it. When I leave the controller with it's view I DO NOT remove the observer (intentionally) in viewDidUnload. Next time when opening the view, the observer gets added again, but now when the observed notification gets posted - I get EXC_BAD_ACCESS.

Can anyone explain why this is happenning.

P.S. I do know that I should remove it in viewDidUnload I'm just curious about the lower level details.

Ignoring the fact that eval is probably super dangerous to use here (unless the data in somefile is controlled by you and only you), there are a few issues to fix in your example code.

In your for loop, alert_list needs to be $alert_list.

Also, as pointed out by @choroba, you should be using != instead of -ne since your input isn't always an integer.

Finally, while debugging, you can add set -x to the top of your script, or add -x to the end of your shebang line to enable verbose output (helps to determine how bash is expanding your variables).

This works for me:

#!/bin/bash -x data=2.2 version=1 al_ap_version=('ap_version' '[[ $data != $version ]]') alert_list='al_ap_version' for alert in $alert_list; do condition=$(eval echo \${$alert[1]}) if eval "$condition"; then echo "alert" fi done

27657784 0 How to extract the result of a query from JSON inside a custom javascript function in OrientDB

I created a custom javascript function in the OrientDB Studio. The function takes a rid as an argument and performs a select query from that rid.

var graph = orient.getGraph(); var res = graph.command( "sql", "select outE('Rel').inV('B').size() as lower_num from " + rid );

So, the result of this query is a number. Depending on the value of this number the function should do different things. I wonder how to extract and use that value from the res variable inside the function. All my attempts have failed so far.. If I return the res variable from the function, the result looks like this:

[ { "@type": "d", "@rid": "#-2:1", "@version": 0, "lower_num": 2 } ]

So, I tried the following ( res[0]['lower_num'] == 2 ); ( res['lower_num'] == 2 ) and nothing worked.. They always returned false. Any ideas?

Let's start by getting some terminology out of the way

A channel is a monaural stream of samples. The term does not necessarily imply that the samples are contiguous in the data stream.
A frame is a set of co-incident samples. For stereo audio (e.g. L & R channels) a frame contains two samples.
A packet is 1 or more frames, and is typically the minimun number of frames that can be processed by a system at once. For PCM Audio, a packet often contains 1 frame, but for compressed audio it will be larger.
Interleaving is a term typically used for stereo audio, in which the data stream consists of consecutive frames of audio. The stream therefore looks like L1R1L2R2L3R3......LnRn

Both big and little endian audio formats exist, and depend on the use-case. However, it's generally ever an issue when exchanging data between systems - you'll always use native byte-order when processing or interfacing with operating system audio components.

You don't say whether you're using a little or big endian system, but I suspect it's probably the former. In which case you need to byte-reverse the samples.

Although not set in stone, when using floating point samples are usually in the range -1.0<x<+1.0, so you want to divide the samples by 1<<15. When 16-bit linear types are used, they are typically signed.

Taking care of byte-swapping and format conversions:

int s = (int) interleavedData[2 * i]; short revS = (short) (((s & 0xff) << 8) | ((s >> 8) & 0xff)) left[i] = ((float) revS) / 32767.0f;

8086193 0 How to iterate over a formset in django?

This is my views.py:

# Create your views here. def codepost(request): if request.method == 'POST': form=CodeFormSet(request.POST) if form.is_valid(): datan = "" for forms in form.ordered_forms: data = forms.cleaned_data['code'] datan = datan + data return render_to_response('submissiondone.html', {'data':datan}) else: form = CodeFormSet() data1=QuestionBase.objects.get(pk=1) #form.append(data1.text) #data1 = mform.text csrfContext = RequestContext(request) return render_to_response('quesdisp.html', {'form': form})

This gives an addition ORDER field which I don't want. So, how do I iterate over a formset? If I remove the can_order = true from the formset, then it is not recognizing "code" as a valid input.

Thus, how do I iterate over this?

Edit: This is the formest part of my forms.py:

from django import forms from django.forms.formsets import formset_factory class CodeForm(forms.Form): code = forms.CharField(widget = forms.Textarea) CodeFormSet = formset_factory(CodeForm, extra = 5, )

i have found the answer to my question. the solution was there lying in my question but at first i was not able to find it. solution was very simple when i wrote i want to use

UiApplication.getUiApplication().getActiveScreen()

that was almost the right way and i was proceeding in right direction but the thing that i was missing was " I was not casting the screen (that i have just retrieved form the stack top ) to its type only thing i should have done is "should have casted screen to its type.like this

UiApplication.getUiApplication().posScreen(this) (MyScreen1) UiApplication.getUiApplication().getActiveScreen()

now i am able to access all the fields on the retrieved screen (MyScreen1)

things to keep in mind

make sure u cast the screen to its type only otherwise bb will give u resource not found error

Benifits of using screen on Stack

u can use already created screen from the stack no need to create new one
if u will create new screen it will be stacked in memory and will consume more and more memory even if its of no use ( make habit to pop the screen if it is of no use instead of leaving it on stack))
no need to create any static variable since u will be able to set all the field right away from other screen

Since you are showing the child form as a dialog, and the parent form doesn't need it until the form as closed, all you need to do is add a property with a public getter and private setter to the child form, set the value in the child form whenever it's appropriate, and then read the value from the main form after the call to ShowDialog.

You need to lerp (linearly interpolate) between the two textures. Your fragment shader needs to hold both textures and then trigger lerping once you load the second texture, the one that you want to change to. Than use operation like col = fromTex.rgb * (1.0-t) + toTex.rgb * t and change the blending/lerping coefficient t throughout the time until you completely blend into the second texture. t can be sent as a uniform that would be slowly changing from the 0.0->1.0 over the time.

You can't call any method from service before it connected. So, you can:

1) add progress dialog "Connecting service..." on activity's start

2) hide progress dialog after service connected and call placeCallWithOption() from onServiceConnected() (not early).

Per ngInfiniteScroll's test case of infinite-scroll-immediate-chec, If this parameter is set as true (the default value), meanwhile the directive's element can not fill up the browser window' height, it will trigger a loadMore() immediately even you don't scroll your window at all. And this action will only be triggered once, therefor if there are 3 three tiny results on first load and they don't reach the bottom, function loadMore() won't be triggered until you scroll the window.

While if this parameter is set as false, you have to trigger the first call of loadMore manually or programmably.

How can I fill the non-transparent areas of a PNG UIImage with a linear gradient? I'd like to reuse a PNG shape for MKAnnotationViews, but change the gradient per annotation's properties.

If you want to send a parameter to another page, then you need to set the url and query string in the href tag of an a tag.

For example:

<a id="myatag" href=""> <!-- Whatever you want the user to click--> </a>

and the js:

document.getElementById("myatag").href = "OrderPrint.html?image=" + "sniperImg" + i;

Then, you can retrieve the name of the image on the server side script, and append ".jpg" or whatever extension you are using. For example, in PHP:

$image = "VideoImages/" + $_GET["image"] + ".jpg";

I think you missed 2 quotes and a +.

$('input[name=choices' + k + ']').val();

You can match number with decimals only or numbers with integer and decimal parts:

for (var x in arr = ["ZAR 200.15", "300.0", "1.02", "29.001", "10"]) { // decimal part only console.log(x, arr[x].match(/(\d+)(\.\d+)?/g)) // integer + decimal part console.log(x, arr[x].match(/(\d+\.\d+)/g)) }

Others have already told you that what you've asked for isn't possible, as HTML attributes must be plain text, not more HTML.

They've also told you that there are Javascript and JQuery libraries which will help you do what you're wanting to do. There are loads of scripts you could use, here's a link to one that you might want to try: http://bassistance.de/jquery-plugins/jquery-plugin-tooltip/

However, I feel I should add one further point which others have missed, and which is actually quite important:

You're using the wrong attribute.

The alt attribute is not the correct attribute to use for a hover tooltip effect. You should be using the title attribute for this.

Using alt works this way for historic reasons in some browsers (I believe it works in IE, but not much else), but it is not intended as a tooltip. The correct use of alt is for a small bit of descriptive text that will appear if the image is not loaded. This could be because the file failed to load, or the user has images turned off, or the user has a text-to-speech browser, etc, but if the image is displayed, then this text should never be displayed.

The title attribute on the other hand is intended to be displayed, and all browsers implement it as a tooltip (in fact, it's not just on <img> tags; you can use title for any element).

Hope that helps.

Instead of checking null try below code

 Windows.Storage.ApplicationDataContainer localSettings = Windows.Storage.ApplicationData.Current.LocalSettings; if (!localSettings.Values.ContainsKey("waslaunched")) { localSettings.Values.Add("waslaunched", "launched"); }

Since you're using PS3+, instead of joining the lines (it's slow), read the file as one string via -Raw:

$content = Get-Content $filepath -Raw | ConvertFrom-Json

Filtering by name, showing contents without name:

$name = 'Child1' $content.Root.$name | ConvertTo-Json

In PS2.0:

$content.Root | Select -expand $name | ConvertTo-Json

Filtering by name, showing name and contents:

$name = 'Child1' ($content.Root | select $name | ConvertTo-Json) -replace '^.|.$',''

Filtering by Id, showing contents:

$content.Root | ForEach { $_.PSObject.Properties.Value | Where Id -eq 2 } | ConvertTo-Json

Filtering by Id, showing name and contents of the node:

($content.Root | ForEach { $_.PSObject.Properties | Where { $_.Value.Id -eq 2 } | ForEach { @{$_.Name = $_.Value} } } | ConvertTo-Json ) -replace '^.|.$',''

I believe there are a few questions asked, so I will answer them accordingly in the comments:

I'd like the label to display the current selection of the date picker

updating every time the date picker is adjusted

in the format as the following, Sunday 9th February 2014 14:00

set the picker so that users can only choose a date and time in the future, nothing from the past!

//declared as a property UIDatePicker *dateTimePicker; NSDateFormatter *dateFormatter; UILabel *lblDateDisplay; NSDate *selectedDate; //in your viewdidload dateFormatter = [[NSDateFormatter alloc] init]; dateTimePicker = [[UIDatePicker alloc]initWithFrame:CGRectMake(0, 0, 300, 220)]; //whatever you want it, I am just listing an example [dateTimePicker setDatePickerMode:UIDatePickerModeDateAndTime]; [dateTimePicker setHidden:NO]; [dateTimePicker setDate:[NSDate date]]; [dateTimePicker setMinimumDate: [NSDate date]]; //no.4 [dateTimePicker addTarget:self action:@selector(dateChangedValue) forControlEvents:UIControlEventValueChanged]; //no.2 //create another method called, dateChangedValue - (void) dateFromChangedValue { selectedDate = dateTimePicker.date; [dateFormatter setDateFormat:@"EEEE dd MMM YYYY HH:mm"]; //no.3 lblDateDisplay.text = [NSString stringWithFormat:@"%@", [dateFormatter stringFromDate:selectedDate]; //no.1 }

There, I am done. I guess you could try these codes.

Get the query text of your view.

SELECT text FROM dba_views WHERE owner = 'the-owner' AND view_name = 'the-view-name';

Parse. Search for view names within the query text.
Get the query text for each view name found. (see item 1.)
Replace each view name in the query with the related query text.
Do this recursively until there are no more views found.

Easy?

EDIT: The above instructions do not do everything required. Thinking about this a little more it gets hairy, grows legs, and maybe another arm. Finding column names, and column names that might be elaborate functions and subqueries. Bringing it all back together with the joins and clauses. The resulting query might look very ugly.

Somewhere within Oracle there may be something that is actually unwrapping a view. I don't know. I am glad I didn't use views that much in Oracle.

The ODP.NET managed data provider does not support code-first development with the Entity Framework. From its readme.txt in odp.net/doc under the oracle client dir:

"7. ODP.NET 11.2.0.3 does not support Code First nor the DbContext APIs."

You'll have to use the model-first or database-first approach.

I suggest kind of meet in the middle algorithm:

 A[i] + B[j] + C[k] + D[l] = 0

actually means to find out A[i] + B[j] and C[k] + D[l] such that

 (A[i] + B[j]) == (-C[k] - D[l])

We can put all possible A[i] + B[j] sums into a dictionary and then, in the loop over -C[k] - D[l], try to look up in this dictionary. You can implement it like this:

 private static int FourSumCount(int[] A, int[] B, int[] C, int[] D) { // left part: all A[i] + B[j] combinations Dictionary<int, int> left = new Dictionary<int, int>(); // loop over A[i] + B[j] combinations foreach (var a in A) foreach (var b in B) { int k = a + b; int v; if (left.TryGetValue(k, out v)) left[k] = v + 1; // we have such a combination (v of them) else left.Add(k, 1); // we don't have such a combination } int result = 0; // loop over -C[k] - D[l] combinations foreach (var c in C) foreach (var d in D) { int v; if (left.TryGetValue(-c - d, out v)) result += v; } return result; }

As you can see, we have O(|A| * |B| + |C| * |D|) complexity; in case A, B, C and D arrays have the approximately equal sizes N the complexity is O(N**2).

One solution is to use pango's cairo bindings. Using it could get quite confusing really fast so here's a essentials. You could create class around it in C++ if you want.

#include <pango/pangocairo.h> // Pango context PangoContext* pangoContext = pango_font_map_create_context( pango_cairo_font_map_get_default()); // Layout and attributes PangoLayout* pangoLayout = pango_layout_new(pangoContext); pango_layout_set_wrap(pangoLayout, PANGO_WRAP_WORD_CHAR); pango_layout_set_width(pangoLayout, maxWidth * PANGO_SCALE); pango_layout_set_height(pangoLayout, maxHeight * PANGO_SCALE); // Set font PangoFontDescription* fontDesc = pango_font_description_from_string("Verdana 10"); pango_layout_set_font_description(pangoLayout, fontDesc); pango_font_description_free(fontDesc); // Set text to render pango_layout_set_text(pangoLayout, text.data(), text.length()); // Allocate buffer const cairo_format_t format = CAIRO_FORMAT_A8; const int stride = cairo_format_stride_for_width(format, maxWidth); GLubyte* buffer = new GLubyte[stride * maxHeight]; std::fill(buffer, buffer + stride * maxHeight, 0); // Create cairo surface for buffer cairo_surface_t* crSurface = cairo_image_surface_create_for_data( buffer, format, maxWidth, maxHeight, stride); if (cairo_surface_status(crSurface) != CAIRO_STATUS_SUCCESS) { // Error } // Create cairo context cairo_t* crContext = cairo_create(crSurface); if (cairo_status(crContext) != CAIRO_STATUS_SUCCESS) { // Error } // Draw cairo_set_source_rgb(crContext, 1.0, 1.0, 1.0); pango_cairo_show_layout(crContext, pangoLayout); // Cleanup cairo_destroy(crContext); cairo_surface_destroy(crSurface); g_object_unref(pangoLayout); g_object_unref(pangoContext); // TODO: you can do whatever you want with buffer now // copy on the texture maybe? delete[] buffer;

In this case buffer will contain 8 bit alpha channel values only. Fiddle with format variable if you want something else. Compiling... pkg-config --cflags --libs pangocairo should do it on linix. I have no idea about windows.

Yes, you might run into trouble. See this link for how to solve your problem.

@Service are constructed twice

The way you proceed when creating modules seems valid to me. You have a context.xml file for each module and all will get loaded once you load the application. Your modules are self-contained and can also be used in different environments. That's pretty much the way I'd also do it.

A local branch can only track a remote branch for pushing if the local and remote branches have the same name. For pulling, the local branch need not have the same name as the remote branch. Interestingly, if you setup a branch 'foo' to track a remote branch 'origin/bar' (with 'git branch foo origin/bar') and if the remote repository does not currently have a branch named 'foo', then if later the remote does get a branch named foo, then the local branch foo will track origin/foo thereafter!

$ git clone dev1 dev2 Cloning into 'dev2'... done. $ cd dev2 # # After clone, local master tracks remote master. # $ git remote show origin * remote origin Fetch URL: /Users/ebg/dev1 Push URL: /Users/ebg/dev1 HEAD branch: master Remote branch: master tracked Local branch configured for 'git pull': master merges with remote master Local ref configured for 'git push': master pushes to master (up to date) # # Create branch br1 to track origin/master # $ git branch br1 origin/master Branch br1 set up to track remote branch master from origin. # # br1 tracks origin/master for pulling, not pushing # $ git remote show origin * remote origin Fetch URL: /Users/ebg/dev1 Push URL: /Users/ebg/dev1 HEAD branch: master Remote branch: master tracked Local branches configured for 'git pull': br1 merges with remote master master merges with remote master Local ref configured for 'git push': master pushes to master (up to date) # # Go to the origin repo and now create a new 'br1' branch # $ cd ../dev1 $ git checkout -b br1 Switched to a new branch 'br1' # # Go back to dev2, fetch origin # $ cd ../dev2 $ git fetch origin From /Users/ebg/dev1 * [new branch] br1 -> origin/br1 # # Now local branch 'br1' is tracking origin/br1 for pushing # $ git remote show origin * remote origin Fetch URL: /Users/ebg/dev1 Push URL: /Users/ebg/dev1 HEAD branch (remote HEAD is ambiguous, may be one of the following): br1 master Remote branches: br1 tracked master tracked Local branches configured for 'git pull': br1 merges with remote master master merges with remote master Local refs configured for 'git push': br1 pushes to br1 (up to date) master pushes to master (up to date)

So br1 was originally supposed to pull/push from master and we end up with br1 pulling from origin/master and pushing to a branch we never knew existed.

You are getting all 1s because the loop initialization statement int c= x*y will be executed only once for a for loop. That is it is executed the first time when x=1 and y=1 and since, it is given as the loop initialisation statement and not in the loop body, it is never reevaluated. The for loop works as :

The loop initialisation statement is executed only once at the beginning of the loop. After each iteration the loop update expression is executed and the loop condition is reevaluated. for(loop_initialisation;loop_condition;loop_update) { ... }

So you should update c inside the loop, something like :

for ( int c= x*y; y<= 12; y++) { c = x*y; System.out.print(c + " "); }

I do have libudev installed and the cosponsoring headers.

Some advice would be very appreciated!

Maybe even another simple way to move the mouse to the top left corner as I am still very inexperienced.

If i'm not getting your question wrongly, your question mysql solution would be Get top n records for each group of grouped results

But when we convert our desire query to laravel, so its will look alike:

$Rating1 = Model::whereRating(1)->take(10); $Rating2 = Model::whereRating(2)->take(10); $Rating3 = Model::whereRating(3)->take(10); $result = Model::unionAll($Rating1)->unionAll($Rating2)->unionAll($Rating3)->get();

And its also one query not multiple as per laravel 4.2 docs, If you still confuse to implement it, let me know.

Simple to make on paint, sweating to turn CSS

I've tried to apply this css I created to make it at least a table but got no success. Is there anything else I have to put in my css? I really don't want to use tables.

Not very elegant solution too, but also works and do not require recreating array. Also, you can access the element value.

$array = (array)json_decode('{"123":100}'); $array_keys = array_keys($array); $array = (object)$array; foreach ($array_keys as $key) { if (!isset($array->$key)) { print "What is happening here?"; } else { print "It's OK val is {$array->$key}"; } }

Note $ before key in $array->$key, it is important.

If you can use a library like underscore or lodash (or recreate the methods used here) it can be done like so:

var attributes = ['fruit', 'color']; var fruits = ['apple', 'orange', 'banana']; var colors = ['red', 'orange', 'yellow']; //Combine arrays in to list of pairs //(this would be expanded with each new array of attribute values) //ORDER IS IMPORTANT var zipped = _.zip(fruits, colors); //Map the zipped list, returning an object based on the keys. //Remember the order of the arrays in the zip operation //must match the order of the attributes in the attributes list var result = _.map(zipped, function(item, index) { return _.object(attributes, item); }); console.log(result);

However, the file can be moved or copied via move_uploaded_file(), rename(), or copy(). So where does PHP actually save temporary files during uploading?

10277401 0 Generating all possible permutations for a given base and number of digits

I'm sure this is pretty simple, but I'm stumped for a way to do this. Essentially if I have an array with P collumns and V^P rows, how can I fill in all the combinations, that is, essentially, all possible numbers in base V of P digits. For example, for P=3 and V=2:

000 001 010 011 100 101 110 111

Keep in mind that this is an 2 dimensional array, not an array of ints.

For P=4 and V=3.

0000 0001 0002 0010 0011 0012 ....

Having this array generated, the rest of work for what I'm trying to devolop is trivial. So having some code/tips on how to do this would be greatly appreciated. Thanks.

21665479 0 How to skip/ignore a specific position (on a list) within a loop, in C language?

A beginner in C language, I have to find the second and third smallest numbers from a list of N numbers.

void MenordeN (int N, int lista[100], int *c,int *posicion) { int menor,cont; menor=lista[0]; for (cont=1;cont<N;cont++) { if (lista[cont]<menor) { menor=lista[cont]; *posicion= cont+1; } } *c=menor;

}

int main() { int lista[100],menor, n, con,res,pos; printf("Ingrese el valor de N: \n"); scanf("%i",&n); printf("Ingrese %i numeros: \n",n); for (con=0;con<n;con++) { scanf("%i",&lista[con]); } MenordeN(n,lista,&res,&pos); printf("El elemento menor es: %i en posicion %i",res,pos); //*res is the answer(smallest number)

As of now: void MenordeN is to find the smallest number and its position. Main calls void MenordeN. However, how do I skip posicion[res] so that I can call void MenordeN again to find the second smallest number?

int low = lista[0],m,i,idx; // init with first array element. m = low; for( i=0; i<3; ++i) { for(idx=0; idx<=100; ++idx) { if (lista[idx]>low) { m = MIN(m,lista[idx]); } } } printf("\n3rd lowest value is %d\n", m); return 0;

----->This just prints the first value entered, not the third smallest.

int main() { int lista[100],menor, n, con, res, pos,resp; printf("Ingrese el valor de N: \n"); scanf("%i",&n); printf("Ingrese %i numeros: \n",n); for (con=0;con<n;con++) { scanf("%i",&lista[con]); } MenordeN(n,lista,&res,&pos); printf("El elemento menor es: %i en posicion %i",res,pos); res=NULL; MenordeN(n,lista,&resp,&pos); printf("\nEl segundo elemento menor es: %i en posicion %i",resp,pos); return 0;

---------------> I know this is wrong, but isn't there something simpler like res=NULL or lista[res]==NULL? My teacher wouldn't expect anything too complicated because we are still in programming I.

27222363 0 R: How to count number of 1 and write to vector

I have as signal-vector that looks like this:

a <- c(1,1,1,1,1,0,0,0,0,1,1,0,0,0,1,0,1,0,1,0,1,0,0,0,0,0,0,0,0,0,0,0,1,1,1)

I will count how often a 1 occurs in one raw and write that in to a vector b e.g. for vector a it should result in:

b
5,2,1,1,1,1,3

The reason is that i will plot a histogram that shows me the distribution of the length of the events. Maybe there is already a function in R that does exactly that? Otherwise with if-loop?

38432624 0 Fast inserting or updating data from huge JSON to MYSQL with php

In a project of mine I have a problem updating my mysql db from a huge json. the json object in question consist of ~1000 entries like this:

[{ "uniqueId":"578742901714e", "lat": -76.760541, "lng": 121.289062, "description":"foo and bar", "visible": true }]

In order to compare the data in the json to the database, I used different statements enclosed in different loops. While this worked it took some time ~45 seconds for the whole json to be processed and written.

Edit:

To clarify, I loop through the array returned by json_decode() and compare the data directly to the Database via SELECT and INSERT STATEMENTS - which works but is slow as hell, because the data is huge

Because the user has to wait for this to ensure data integrity, I decided this should be sped up.

So I looked using INSERT INTO ON DUPLICATE KEY UPDATE, which should work with multiple data sets.

But here's the real problem: Because some entries like "description" are saved in their own table I need something like LAST_INSERT_ID() to know the auto-increment id of the just inserted dataset. But LAST_INSERT_ID() doesn't work that way and only returns the first row if it is used in a batch INSERT. (Documentation)

So I'm stuck between a functioning but very slow execution and a non-functioning but (supposedly) very fast execution.

I don't really know how to proceed, can you help me?

Edit:

The database in question consists of some tables. The most prominent ones are the following two:

table poi:

#1 id int auto-increment primary #2 unique_id varchar(13) unique #3 date int(11) #4 visible tinyint(1)/bool

table poi_description:

#1 id int auto-increment primary #2 poi_id int(11) #3 description text #4 date int(11) #5 user int(11)

I read so much in the last two days that I'm really not sure how to update the rows if the uniqueid is already in the table. I thought, I could get it to work with INSERT ON DUPLICATE UPDATE, but that looks only for the primary key - at least that's how it looks to me.

Your script is looking for a DOM element with ID "overlay" which does not exist. The id of the button is btnAddUser.ClientID

<asp:Button runat="server" ID="btnAddUser" Text="Add Currency Combination" ValidationGroup="valSum2" CssClass="showHide" /> <script type="text/javascript" language="javascript"> $(document).ready(function() { $('<%= btnAddUser.ClientID %>').click(function() { $.blockUI({ overlayCSS: { backgroundColor: '#00f' } }); setTimeout($.unblockUI, 2000); }); }); </script>

Note the removal of OnClientClick!

Alternatively you can make this code a named function and type its name in the OnClientClick property. You can also bind by CssClass ( $('.showHide') ) (see @PraveenVenu's answer) but this will bind the function to all elements that use this css class.

Not completely sure if I understand what you are trying to do, but I gave it a shot.

In the CSS if you change the margin to padding, then any background color on the child element will extend to the parent. background color is includes the padding but not the margin.

I also had to bump up the width of the child 20px for it to fill properly.

Updated fiddle: https://jsfiddle.net/5qp1a3um/1/

.inner{ padding-left: 100px; padding-right: 100px; background-color: blue; width: 220px; height: 300px; border: 1px solid green; }

21652345 0 From inside a custom directive how to change text of another span element?

I have an <input> which holds my custom directive as an attribute and inside that attribute I give the ID of destination that will receive the text. At the moment I am doing the text change with jQuery but I would rather use the full Angular way...So it's kinda of a binding but from within a directive. To make it simple, I made a simple draft of my code:

HTML Code

<input type="text" name="input1" my-directive="message1" /> <span id="message1"></span>

JS Code

// Angular - custom Directive directive('myDirective', function($log) { return{ require: "ngModel", link: function(scope, elm, attrs, ctrl) { var receiverId = attrs.myDirective; var whateverText = 'blabla'; $('#'+receiverId).text(whateverText); } }; });

Using the ID on my <span> element is probably not the best solution, but that is how I got it working with jQuery. It's probably better to remove the ID, but then how could I update the text in my span after all? And let's not forget that it's a Form and we can have multiple input and span elements. Also note that I do not want to use the controller to pass the text, it has to stay within the directive as I want to re-use it.

Please don't tell me that I shouldn't do it this way, I want to stick with this behavior.

The problem is as others in the comments mentioned, that your javascript resource is not precompiled.

The solution is a little bit more than just making sure you precompile the assets, which by the way heroku will do when you push so you don't have to.

The problem lies in that you are doing this:

<% content_for :script do %> <%= javascript_include_tag 'hover_content' %> <% end %>

Since you are referencing hover_content directly instead of just including it in your application.js then you must tell Rails that you want this included in the asset precompile step.

Modify your production.rb file and add this line:

config.assets.precompile += %w( hover_content.js )

That will tell rails that in addition to the application.js which automatically gets compiled and included that you want to also include this other file hover_content.js

17983180 0 Updating Yii Dropdownlist After Insert New Element [SOLVED]

I'm totally new in Yii, so, excuse me if the answer for this question is a little bit trivial.

Here's my code:

<p> <?php echo $form->labelEx($model,'phone_type'); ?> <span class="field"> <?php echo $form->dropDownList($model,'phone_type', CHtml::listData(PhonesTypes::model()->findAll(), 'id','type' )); ?> <?php echo $form->error($model,'phone_type'); ?> </span> </p>

There will be a button to register new Phone types. So, after the submition of the form, that will be inside of a CJUiDialog, I wish that the above dropDownList be updated with the new type, without refresh the page.

I google it a lot, but i only find things related to "dependent dropdowns" in Yii.

What's the better approach to solve this problem? Is there something like $.fn.cgridview.update?

Here's the Dialog code:

<?php $this->endWidget('zii.widgets.jui.CJuiDialog'); $this->beginWidget('zii.widgets.jui.CJuiDialog', array( 'id'=>'dialog-crud', 'options'=>array( 'title'=>'Create new Phone Type', 'autoOpen'=>false, 'modal'=>true, 'width'=>1080, 'height'=>820, 'resizable'=>false ), )); ?> <iframe src="http://myapp/phone_types/create" width="100%" height="100%"></iframe> <?php $this->endWidget(); ?>

And the code of the controller, is a trivial create function:

public function actionCreate(){ $model = new PhoneType; if(isset($_POST['PhoneType'])){ $model->attributes = $_POST['PhoneType']; if( $model->save() ){ //----> some suggestion here? echo CHtml::script(""); Yii::app()->end(); } } }

So, below is the code of my solution. In the view:

<?php $this->beginWidget('zii.widgets.jui.CJuiDialog', array( 'id'=>'dialog', 'options'=>array( 'title'=>'Phone Types', 'autoOpen'=>false, 'modal'=>true, 'width'=>1080, 'height'=>820, 'resizable'=>false ), )); ?> <iframe src="phoneTypes/create" id="cru-frame" width="100%" height="100%"></iframe> <?php $this->endWidget(); ?>

In my PhoneTypesController:

public function actionCreate(){ $model = new PhoneTypes; if(isset($_POST['PhoneTypes'])){ $model->attributes = $_POST['PhoneTypes']; if($model->save()){ echo CHtml::script(" window.parent.$('#dialog').dialog('close'); window.parent.$('#Phone_types_id').append('<option value=".$model->id." >'+'".$model->type."'+'</option>'); "); Yii::app()->end(); } } $this->render('create',array( 'model'=>$model, )); }

Thanks for your help!

You could use this:

If this was your url:

url(r'(?P<category>[a-z]+)$', 'display', name='dyn_display') reverse('dyn_display', kwargs={'category': 'first'})

To redirect you can use it like this in your view:

from django.http import HttpResponseRedirect return HttpResponseRedirect(reverse('dyn_display', kwargs={'category': 'first'}))

If this was your url:

url(r'$', 'display', name='dyn_dysplay') reverse('dyn_display')

To redirect you can use it like this in your view:

from django.http import HttpResponseRedirect return HttpResponseRedirect(reverse('dyn_display'))

To have a view that could receive an optional value you would need 2 urls:

url(r'$', 'display', name='dyn_optional_display') url(r'(?P<category>[a-z]+)$', 'display', name='dyn_display')

And then your view:

def courses_display(request, category=None): ctx = {} if category: ctx.update({category: 'in'}) return render_to_response('display/basic.html', ctx, context_instance=RequestContext(request))

I've forked that project and made a Heroku Button deployable version here. In order to get that working, I checked out the sample app, and found that the build dumped the binary in .build/release/PerfectTemplate, so your Procfile should be:

web: .build/release/PerfectTemplate --port $PORT

Note, you also want to set the $PORT. If you've deployed but failed prior to this, you'll also want to make sure you scale up the web dyno: heroku ps:scale web=1.

I would like to set startAt as an number.

SomeClass.prototype.startAt is a number (0).

Your get function explicitly returns false if the property is "falsey":

if(!this[prop]){return false;}

In JavaScript, 0, "", false, undefined, and null are all "falsey", and so the condition above will be true and cause get to return false.

If your goal is to return false if the property doesn't exist, you can do that like this:

if (!(prop in this)) { return false; }

That will check if the property exists on the object itself or its prototype, which I suspect is what you want. But if you only want to check the object itself and ignore properties on the prototype, that would be:

if (!this.hasOwnProperty(prop)) { return false; }

Bringing that all together, if your goal is for get to return false for properties that the object doesn't have (either its own, or via its prototype), then:

get : function(prop){ if (typeof prop !== "string" || !(prop in this)) { return false; } return this[prop]; }

I've done a few things there:

typeof is an operator, not a function, so you don't use parens around its operand (normally)
Since "undefined" is !== "string", there's no need to check for it specifically when checking that prop is a string.
I used !(prop in this) to see if the object (or its prototype) has the property.
I combined the two conditions that returned false into a single if statement using ||.

You should first learn about SASS

You will see that SASS is actually CSS made easy and with more features like the ability to use Variables : $myHeight : 500px;

In your example, he is using variable.

To inject it in your project, you need to find a way to save your SASS file in a CSS file. In the above link it is using the command

sass --watch app/sass:public/stylesheets

But you can also do it with grunt or gulp

You must have a lot of lines. Are you sure that the second row repeats enough to put those records into an individual file? Anyway, awk is holding the files open until the end. You'll need a process that can close the file handles when not in use.

Perl to the rescue. Again.

#!perl while( <> ) { @content = split /,/, $_; open ( OUT, ">> $content[1]") or die "whoops: $!"; print OUT $_; close OUT; }

usage: script.pl your_monster_file.csv

outputs the entire line into a file named the same as the value of the second CSV column in the current directory, assuming no quoted fields etc.

You can look into jQuery to dynamically change CSS properties as the certain events are called. You can find a great tutorial here. Here is an example from an old project of mine:

 $(window).scroll(function (e) { $el = $('.fixedElement'); if ($(this).scrollTop() > 98 && $el.css('position') != 'fixed') { $('.fixedElement').css({ 'position': 'fixed', 'top': '0px', 'width': '90%', 'min-width': '1200px' }); } });

This is what you want to use:

sort -t: -k 1.5,1.8n -k 2.1,2.7n inputfile 440c0401 mfcc.1.ark:9 440c0401 mfcc.1.ark:501177 440c0402 mfcc.2.ark:15681 440c0403 mfcc.3.ark:516849

-t -separator of fields(should not be used elsewhere in the inputfile

-k is key for sorting(could be used > 1) -k 1.5,1.8n means: sort numerical(this tells the n) by the field 1 from 5th to 8th character.

second -k tells sort the field 2 from the first to the 7th character numerically.

From what I can tell, there doesn't seem to be a way using streaming to send certain records in output file A and the rest of the records in output file B.

By using a custom Partitioner, you can specify which key goes to which reducer. By default the HashPartitioner is used. Looks like the only other Partitioner Streaming supports is KeyFieldBasedPartitioner.

You can find more details about the KeyFieldBasedPartitioner in the context of Streaming here. You need not know Java to configure the KeyFieldBasedPartitioner with Streaming.

Is there a way to do a map/reduce job to re-split every log files correctly?

You should be able to write a MR job to re-split the files, but I think Partitioner should solve the problem.

Based on my comments above, below is a workaround. Unfortunately at this stage, Windows 8.1 store Unit Test project types, using NUnit extension wouldn't work due to the different .NET targets. I tried with different Test Unit Adapters including an NUnitTestAdapterWithFramework.

It seems that the issue you haveing was occurring with standard .NET libraries targeting NUnit test adapter but the above NUnitTestAdapterWithFramework must have fixed those issue. See the Q & A section of the NUnitTestExtension

But unfortunatly it seems that this still of an issue that hasn't been fixed for Win8 Store App type Unit Testing. Pretty sure xUnit.NET also not compatible yet with different .NET target types (i,e WinRT)

So what are the options? a. For your group, you can change them to use MSTest framework. Outcome - Problem Solved no issues.

b. Workaround "linked project". Outcome - Can't *guarantee** but this should also work.

With option 'b'

In your comment you mentioned.

but I'm still not sure what it does or how to implement a 'linked project', do you have any more information on this? Also, as this is for a group university project, I was hoping i wouldn't have to force too many workarounds

When you think about it, it is not really hard work around. It is simple and I'm sure your group would be able to apply this workaround easily.

Please follow the below steps.

Create a separate class library in your solution (you can target .NET framework 4).
Then add NUnit assemblies and the NUnit test adapter as usual.
Right click on this project and select 'Add' then 'Existing Item'
Select the Win8 Store Unit Test project and locate the Unit Test file you want to add. When you add the file, make sure you select 'Add As a Link' button. Please see below.
Now rebuild the solution, close and re-open the UnitTest explorer and you should be able to run those tests.

enter image description here

*The reason I said can't guaranteed. I haven't really written Unit tests against Win8 App. So if your SUT (System Under Test) require special configuration it might cause issues. But I'm not sure.

Finally creating a link files are not that hard if everything works you can continue to do this until NUnit has the support for Win8 Unit Testing. Or the other option is simply change all your Unit Tests to use MSTest framework if possible.

Ping is used to check if a server is alive. Telnet, normally allows to use the telnet service, but it can be used to check if a port is open (firewall) for remote connections.

You should check connectivity from the client

telnet db2serverName db2Port

For example

telnet 192.168.0.1 50000

Once you have checked that the DB2 port is open for your client, you should establish the connection or receive a different error message.

37129365 0 Contenteditable, bizarre behaviour of child elements, and NOT whitespace independent?

I've been playing around with contenteditable fields, and have come across an odd behaviour that I cannot figure out.

Check out fiddle for this particular problem.

I have two identical contenteditable divs. Both of them have the same <span> child, followed by a single blank character (otherwise carrot issues ensue). The only difference between the two is that the second div has been "prettified", and made more readable by indenting the <span> on a new line.

<div style="margin-bottom: 15px;" contenteditable="true"><span class="lead" contenteditable="false">Something something</span>&#8203;</div> <div contenteditable="true"> <span class="lead" contenteditable="false">Something something</span>&#8203; </div>

Try this in both of the divs...

Place the carrot to the right-end of the content (i.e. after the blank character)
Then hit backspace a couple times

You'll notice that in the top (first) contenteditable div, you can delete the <span> element, as though it were one giant character. You should also notice that that in the second div, no amount of backspacing will ever clear it out. At least not in Safari.

So what gives!? I thought HTML was whitespace independent - why the difference in behaviour of the two?

Viewing the source, they have slightly different markup...

... but it still behooves me as to why there would be any difference.

I would like it to be deletable, and so the solution is obviously just to use the former version, but it is still curious as to why this issue exists at all.

Also! If you happen to be a contenteditable guru, I've been fighting with another issue over here. Any help on that one is welcome!

31004208 0 IE11 - flash (.swf) not working when not connected/offline using appcache (webcam.js)

we are running webcam.js to take pictures inside a html site. We are also using appcache to provide offline access to all of the files.

Everything works fine in Chrome (43.0.2357.124) regardless of the connection (online/offline). When using the same site in Internet Explorer (11.0.9600.17842) we are expiriencing problems when using the webcam.js to take pictures.

When the device is online, everything works as planned but as soon as the device goes offline, the execution/initialization of the flash plugin seems to fail (only a blank space and when you right click, it says 'could not be loaded). You can see in the network tab inside the developer tools that the webcam.swf has the status '(aborted)'.

The status of the webcam.swf when the device is online is 304 - so it seems that it is loaded from cache, which is fine.

We also created several testcases where we were using several different swf files and a stripped down appcache manifest, but couldn't get it to work inside IE 11 (Windows 8.1). Neither inside the metro or desktop version of the browser. We also tested on 3 different devices, but still no luck.

Any ideas what is causing this problems in IE? Thanks in advance!

You're using img tags with background-image. I honestly don't know what browser support is for that, but it's a bad idea. Instead use divs. You'll also need to make the styles forcing it to inline block. Alternatively, you could go with something like font awesome/glyphicon's strategy of ::before styling, usually used with spans.

<!DOCTYPE html> <html> <head> <style type="text/css"> .outdoor { background-image: url(sprites.png); background-repeat: no-repeat; background-position: -14px -110px; width: 20px; height: 20px; display:inline-block; } .parking{ background-image: url(sprites.png); background-repeat: no-repeat; background-position: -15px -60px ; width: 20px; height: 20px; display:inline-block; } </style> </head> <body> <h1>Hello Sprites.. Why are you appearing in Chrome, but not in Firefox? Please appear</h1> <div class="outdoor" ></div> <div class="parking" ></div> </body> </html>

As explained by @nos in a comment, pressing ctrl+space in Eclipse will popup a tooltip that highlights (in bold) the parameter where the cursor is, as illustrated in in image provided by @nos:

However, that still requires IDE support and is relatively cumbersome to use (you have to position cursor and trigger it to use it), so you should consider other means.

No method should take 24 parameters, but if you absolute must, then your should comment all parameter values that are not self-explanatory, e.g. year and name are probably explanatory enough, but values like null, 0, false, 42, true, etc. does not convey meaning, so you should comment them:

src.myFunction(year, name, /*address1*/null, /*address2*/null, /*city*/null, /*state*/"NY", /*zipcode*/null);

That way a casual observer will know exactly what the values mean.

Another way to do this is to wrap all the parameter values in a POJO and use the builder pattern.

src.myFunction(new MyPojo() .setYear(year) .setName(name) .setState("NY"));

You can try swapping backgrounds like so:

Create CSS Class for each background and include transitions as part of the ruleset:

.background-1 { background: url('background-1.jpg'); -webkit-transition: background 500ms linear; -moz-transition: background 500ms linear; -o-transition: background 500ms linear; -ms-transition: background 500ms linear; transition: background 500ms linear;

}

Add a script that will swap out the classes on a regular interval. (You would most likely wrap this script within $(document).ready) Since your transitioning backgrounds, you may not want the previous background immediately removed, so you can use a delay call to remove it after the transition would complete.

The following example would start the background switch every two seconds, and remove the previous background after 1 second. Since in my CSS, I declared that the transition should take .5 seconds, the new background is already there before the old one is removed:

setInterval(function() { if($('#background').hasClass('background-1')) { $('#background').addClass('background-2'); setTimeout(function() { $('#background').removeClass('background-1'); }, 1000); } else if($('#background').hasClass('background-2')) { $('#background').addClass('background-1'); setTimeout(function() { $('#background').removeClass('background-2'); }, 1000); } }, 2000);

Note: The code that I've provided would require you to chain multiple if/else if statements together, there is probably a more efficient way to go about this.

I've done something similar (background colors instead of images) as a teaser for an upcoming project of mine, you can check it out here.

Update: Forgot to mention, make sure to declare one of the background classes in your Div element:

<div id="background" class="background-1"></div>

well, i don't quite understand why your button don't respond, because i've came across similar problems but i've used different solutions. here's what i've done:

CGRect reuseableRect = CGRectMake(20, 290, 260, 37); self.actionButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; self.actionButton.frame = reuseableRect; [self.actionButton setTitle:@"Initialize" forState:UIControlStateNormal]; [self.actionButton addTarget:nil action:@selector(performAction) forControlEvents:UIControlEventTouchUpInside]; [self addSubview:self.actionButton];

Actually, i did this :

self.actionButton = [[UIButton alloc] initWithFrame:reuseableRect];

but it didn't work. so i changed it into

self.actionButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];

the resueableRect is just a CGRect that I've used all through the view initialization.

as for the three lines of your previous solution, the first one:

[self setSelectionStyle:UITableViewCellSelectionStyleNone];

it's doing some configurations to the tableView and its cells, so it's not going to affect the button

the second one:

cell.userInteractionEnabled = NO;

it's not configuring the button as well, what's more, since the cell is the super view of the button, this line prevents any user interactions.

the third one is not doing anything to the button as well, so i recommend that you delete all of them if you were thinking about configuring the button

Because you work with statically allocated arrays you probably stumbled upon writing after the end of the array.

You state that the file has exactly 21 entries but what happens with the eof condition? If you read the last entry, the stream still doesn't have the eof bit set. This only happens when you try to read and there is nothing. After the 21st entry, the loop still continues because the eof bit is not set. It reads garbage information and tries to store it into paInventory[21], but the array was only 21 in size.

//after last read x=21 and eof not set while (!InputInventory.eof () ) { //first read causes eof to be set InputInventory >> iTempPluCode >> sTempDescription >> dTempPrice >> iTempType >> dTempInventory; //Accessing paInventory[21] here which causes your error paInventory[x].setiPluCode(iTempPluCode); //...// }

The extra "stuff" is there because you've passed the buffer size to memcpy. It's going to copy that many characters, even when the source is shorter.

I'd do things a bit differently:

void copy_string(char *dest, char const *src, size_t n) { *dest = '\0'; strncat(dest, src, n); }

Unlike strncpy, strncat is defined to work how most people would reasonably expect.

After wondering for hours through different advices, this one worked for me (Installed via MacPorts):

Courtesy of Chris Brewer:

Download and install MacPorts from http://macports.org.

The following steps are performed in the Terminal:

Force MacPorts to update (will only work if Apple's Xcode installed):

sudo port -v selfupdate

Now, install memcached:

sudo port install php5-mcrypt

Copy the newly created shared object for mcrypt into Mac OS X’s default PHP5 extension directory:

sudo cp /opt/local/lib/php/extensions/no-debug-non-zts-20090626/mcrypt.so /usr/lib/php/extensions/no-debug-non-zts-20090626/

Next, you need to edit php.ini to add the extensions. Find the phrase Dynamic Extensions, and add:

extension=mcrypt.so

And finally, restart Apache:

sudo apachectl restart

13034355 0 Web Deploy to 2 separate web servers?

I have an MVC3 application that I deploy to IIS 7.5 using the "Web Publish" feature in Visual Studio. I need to setup a 2nd server that will be hardware load-balanced and will mirror the setup on the 1st server.

I am aware of the Web Farm Framework and that is an option, however I don't like the idea of the controller server being the weakest link in the chain. I think I would rather just use the hardware load balancer to direct traffic.

Is it possible to write a manual Web Deploy script that will target 2 separate servers each time it is run?

27279740 0 In spring config xml file all dependency are instantiate for Singleton scope when application context start?

As I know "the instantiation of the application context create the container that consists of the objects define in that XML file.

This XML file is then provided to the ApplicationContext instance, which creates a container with these beans and their object graphs along with relationship .the spring container is simply a holder if the bean instances that where create from the XML file.

I have some confusion: is their all bean instance is create in XML file when applicationcontext create. Or it created when getbean() call? Because if all bean dependency class object is created at context level because of singleton then some of the instance not injected to dependent object reference. Then why we create extra overhead to creating all instance?

Most likely the function is not the bottleneck, but the fact that you are calling it 12 million times :-)

An obvious improvement is having a variable

const char* file_pos = file + pos;

simplifying every single access. You don't say how tline is implemented; if a line never contains more than two words then you can probably make it faster by having two std::string members instead of an array.

MATLAB has a built-in for this. If N is the number of shades you want (471 in your case) you can do

N = 471; c = colormap(jet(N));

then access c in every loop iteration via c(i, :). For reference see the man page ;).

If you don't really care about the IList<T>, you can change your model to IEnumerable<T>. DisplayNameFor method has an overload for IEnumerable, that means you will be able to do this:

@model IEnumerable<PlusPlatform.Models.UserProfile> ... <th> @Html.DisplayNameFor(model => model.UserName) </th>

LabelFor doesn't have this overload, because label should be used for a specific element, such as:

@Html.LabelFor(modelItem => Model[i].UserName)

EDIT:

If you wan to post that data to controller, better create an EditorTemplate, name it UserProfile:

@model PlusPlatform.Models.UserProfile <tr> <td> @Html.EditorFor(m=> m.UserName) </td> <td> @Html.EditorFor(m=> m.FirstName) </td> <td> @Html.EditorFor(m=> m.LastName) </td> <td> @Html.EditorFor(m=> m.DepartmentId) </td> <td> @Html.EditorFor(m=> m.IsActivated) </td> </tr>

Then in the View get rid of the loop:

@model IEnumerable<PlusPlatform.Models.UserProfile> @using (Html.BeginForm()) { <table> <tr> <th> @Html.DisplayNameFor(model => model.UserName) </th> ... </tr> @Html.EditorForModel() </table> }

You can't append to a tuple at all (tuples are immutable), and extending to a list with + requires another list.

Make curveList a list by declaring it with:

curveList = []

and use:

curveList.append(curve)

to add an element to the end of it. Or (less good because of the intermediate list object created):

curveList += [curve]

The short answer is: you use a generational garbage collector.

Except that most modern Java implementations¹ use a generational collector by default. In other words, you (the programmer) don't need to deal with the problem because it is already dealt with.

The only situation where you might run into fragmentation is if you have mis-tuned the low-pause collector and it has fallen back to doing a "stop the world" full collection. At that point, you might be using a non-compacting collector, and fragmentation might ensue. But the solution there is to adjust the tuning (or the application, or the heap size) to avoid getting into that situation.

^{1 - Some really old Java implementations used primitive mark-sweep collectors. But they are long gone.}

Step 1 : the target datastructure :

There are two issues with your data structure :

You're forgetting to put the names between quotes. John should be "John". Mary should be "Mary". etc.
You're trying to use an object for [ "John", "Mary" ] and [ "Paul", "Peter" ], where you should be using an array.

So, the data structure you're looking for, is this :

{ 31 : [ "John", "Mary" ], 24 : [ "Paul", "Peter" ] }

Step 2 : fetching the data from the HTML input :

I suggest you make this small adjustment to your JavaScript code :

var source = []; $('span.members a').each(function () { $.ajax({ url: $(this).attr('href'), success: function (result) { source.push({ name : $(result).find('tr td:contains("Username:")').next().text().trim(), age : $(result).find('tr td:contains("Age:")').next().text().trim() }); } }); });

(see also this Fiddle)

This fetches the data from your HTML input and puts it into a data structure that looks like this :

var source = [{ name : "Paul", age : 24 }, { name : "Mary", age : 31 }, { name : "Peter", age : 24 }, { name : "John", age : 31 }];

Step 3 : converting to the right data structure :

Once you fetched all the data, you only need to convert your data from the source data structure to the target data structure, which is as simple as this :

var convert = function(source) { var output = {}; for(var i = 0; i < source.length; i++) { if(output[source[i].age]) { output[source[i].age].push(source[i].name); } else { output[source[i].age] = [source[i].name]; } } return output; }

(see also this Fiddle)

Putting the pieces of the puzzle together :

You have to wait with executing your convert function until all of your Ajax calls have finished.

For example, you could do something like ...

if (source.length === numberOfMembers) { target = convert(source); }

... right behind the source.push(...) statement.

So if you put all the pieces of the puzzle together, you should get something like this :

var source = []; var target; var $members = $('span.members a'); var numberOfMembers = $members.size(); var convert = function(source) { var output = {}; for(var i = 0; i < source.length; i++) { if(output[source[i].age]) { output[source[i].age].push(source[i].name); } else { output[source[i].age] = [source[i].name]; } } return output; } $members.each(function () { $.ajax({ url: $(this).attr('href'), success: function (result) { source.push({ name : $(result).find('tr td:contains("Username:")').next().text().trim(), age : $(result).find('tr td:contains("Age:")').next().text().trim() }); if (source.length === numberOfMembers) { target = convert(source); } } }); });

36916053 0 How do I obtain values of a curve f(x1,x2) = 0 in R to visualize it?

I have ggplot scatters of points and I'm trying to visualize the different decision boundaries i get with glm. I can grab the coefficients from glm and I end up with something like f(x1,x2) = 0 which could have power interactions so I can't just try abline. What's the simplest way to visualize it on the scatter? I was thinking if there's a "solver" maybe which will return a frame of points on a grid that I can then geom_line maybe?

Do like this way.

public class AppPreferences extends Activity { private SharedPreferences settings = null; AppPreferences(Context context) { settings = context.getSharedPreferences(LOGIN_CREDENTIALS, MODE_PRIVATE); } ...//Rest of your code. }

In Login activity.

PersonView is generated by the DataTemplate for the ItemsControl in CommunityView (CommunityView.xaml:16).

DataTemplates automatically assign the DataContext of their visuals to the data that the template is displaying. This is how WPF works.

CommunityView gets its DataContext set by inheritence from the Window.

The attached command sink property sets the instance CommandSink property on all of the CommandSinkBinding objects contained within the CommandBindings property of the object with the attached property assignment. So in CommunityView.xaml, the CommandSink of all of the CommandSinkBindings in CommunityView (KillAll) are set to the DataContext of the view through binding.

The CommandSink property is used to call the Execute and CanExecute functions on the proper target (the ViewModel in this case).

The Code 39 specification defines 43 characters, consisting of uppercase letters (A through Z), numeric digits (0 through 9) and a number of special characters (-, ., $, /, +, %, and space). An additional character (denoted '*') is used for both start and stop delimiters. Each character is composed of nine elements: five bars and four spaces. Three of the nine elements in each character are wide (binary value 1), and six elements are narrow (binary value 0). The width ratio between narrow and wide can be chosen between 1:2 and 1:3.

Here is a pure CSS solution I quickly hacked up: CSS Hover Effect

h1, h2, h3, h4, h5{ margin:0px; } .tile{ overflow: hidden; width: 400px; height:350px; } .tile:hover > .body{ transition: all 0.5s ease; top: -3em; } .body{ transition: all 0.5s ease; background-color: #333; margin:0px; color: #fafafa; padding: 1em; position:relative; top: -1em; }

<div class="tile"> <img src="http://lorempixel.com/400/300"> <div class="body"> <h2>Test Header</h2> <p>Info to display</p> </div> </div>

Basically, I just change the position of the text div when I hover over the main div and add a transition animation to it.

I did not know about an funktion like you ask for. But maybe you know a time for timeout. So you could use the connection timeout: RestTemplate Constructor

int timeOutMillis = 5000;//example 5 seconds ClientHttpRequestFactory requestFactory; if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) { requestFactory = new SimpleClientHttpRequestFactory(); ((SimpleClientHttpRequestFactory) requestFactory).setConnectTimeout(timeOutMillis); } else { requestFactory = new HttpComponentsClientHttpRequestFactory(); ((HttpComponentsClientHttpRequestFactory) requestFactory).setConnectTimeout(timeOutMillis); } RestTemplate restTemplate = new RestTemplate(requestFactory);

Alternativ you could create an AsyncTask and kill it :)

AsyncTask<Void, Void, Void> task = new AsyncTask<Void, Void, Void>() { @Override protected Void doInBackground(Void... params) { RestTemplate restTemplate = new RestTemplate(); restTemplate.delete("http://example.com"); return null; } }.execute(); //Task run task.cancel(true); //Cancel task and so the request

Hope that would be enough, sorry, but nothing else found in Spring Docs...

If you only want to work with the vision part then AForge.net is your best bet. I have used it in the past and it was pretty good for video/feed stuff. Don't expect to do something with your audio later on though since AForge.NET only supports Vision related stuff. Personally I wouldn't use DirectShow since that is pretty old and sometimes requires you to do some complex interop tricks to get what you want. If you want to go the DirectShow way at least use DirectShow.NET.

It's a bit of a mystery, isn't it? Several superficially plausible theories turn out to be wrong on investigation:

So that the POST object doesn't have to implement mutation methods? No: the POST object belongs to the django.http.QueryDict class, which implements a full set of mutation methods including __setitem__, __delitem__, pop and clear. It implements immutability by checking a flag when you call one of the mutation methods. And when you call the copy method you get another QueryDict instance with the mutable flag turned on.
For performance improvement? No: the QueryDict class gains no performance benefit when the mutable flag is turned off.
So that the POST object can be used as a dictionary key? No: QueryDict objects are not hashable.
So that the POST data can be built lazily (without committing to read the whole response), as claimed here? I see no evidence of this in the code: as far as I can tell, the whole of the response is always read, either directly, or via MultiPartParser for multipart responses.
To protect you against programming errors? I've seen this claimed, but I've never seen a good explanation of what these errors are, and how immutability protects you against them.

In any case, POST is not always immutable: when the response is multipart, then POST is mutable. This seems to put the kibosh on most theories you might think of. (Unless this behaviour is an oversight.)

In summary, I can see no clear rationale in Django for the POST object to be immutable for non-multipart requests.

26699669 0 What will get removed if i remove a pointer in c++

If I remove a pointer to an object, what will be removed? Only the pointer or also the object which the pointer points to? For example:

Assume I have a class with a variable

int *root

If I do the following in a method of that class

int *current = root; delete current;

Will root also be deleted or only the pointer current?

I would suggest using MVC Display/EditorTemplates rather than a helper in this context. With templates you get automatic collection support, and you can use a strongly typed model.

You didn't provide example output or what it's used for but what I'd normally do is create a simple value object. We can also leverage Ruby's Date and Range objects to do most of the heavy lifting.

require 'date' class DateRange def self.import dates dates.map do |d| self.new Date.parse(d[:start_date]), Date.parse(d[:end_date]) end end def initialize start, finish @range = Range.new start, finish end def month Date::MONTHNAMES[start.month] end def mon month[0..2] end def include? date @range.include? date end def start @range.begin end def finish @range.end end def to_s "#<#{self.class.name} #{start.iso8601}..#{finish.iso8601}>" end end

We use start and finish because begin and end are reserved words in Ruby, Range can use them because it is implemented in C. We could delegate to the Range object or use the Range object directly, but this value object lets us expose only the interface we want.

I exposed the include? method which can be used to check if a given date is between the start and finish points, since that's the sort of thing people like to do with date ranges.

Also, we use the MONTHNAMES constant defined on Date to give us the month name, or the short_month name, which is just the first 3 letters of the month, if you're into that.

This code can be used as a starting point for any value object in a system, remove the stuff you don't need, add stuff you want.

Additionally, I've included an import method on the class which will read in your @dates array and return a collection of DateRange objects.

so my question is, can I directly edit the string resources from the xml file?

No, you can't change resources at runtime. But your code seems kind of goofy. This is all going to run when the Activity starts up. So, you can check the message then just set it in your TextView of the layout.

protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_display_message); TextView textView (textView) findViewById(R.id.textView); Intent intent = getIntent(); String message = intent.getStringExtra(MyActivity.EXTRA_MESSAGE); textView.setText(message); }

simply create a TextView inside of activity_display_message.xml (here called textView) then set the text with the message variable.

Also, it is often a good idea to do some error checking such as

if (intent !== null && intent.getStringExtra(MyActivity.EXTRA_MESSAGE != null) { // do your stuff here }

or however you want to go about that.

Storing...

You could store that value in a persistent value such as SharedPreferences, a file, db, etc... if you are wanting to use it later.

You can read more about that here in the docs

12920429 0 Anyone Have MediaPlayer Working with ParcelFileDescriptor and createPipe()?

Related to my recent question on MediaRecorder and createPipe(), and a discussion of the createPipe() technique in this other SO question, I am now trying to get MediaPlayer to work with content served by a ContentProvider via ParcelFileDescriptor and createPipe().

This sample project has my work to date. It is based off of an earlier sample that plays an OGG clip stored as a raw resource. Hence, I know that my clip is fine.

I have changed my MediaPlayer setup to:

 private void loadClip() { try { mp=new MediaPlayer(); mp.setDataSource(this, PipeProvider.CONTENT_URI.buildUpon() .appendPath("clip.ogg") .build()); mp.setOnCompletionListener(this); mp.prepare(); } catch (Exception e) { goBlooey(e); } }

Through logging in PipeProvider, I see that my Uri is being properly constructed.

PipeProvider is the same one as in this sample project, which works for serving PDFs to Adobe Reader, which limits how screwed up my code can be. :-)

Specifically, openFile() creates a pipe from ParcelFileDescriptor:

 @Override public ParcelFileDescriptor openFile(Uri uri, String mode) throws FileNotFoundException { ParcelFileDescriptor[] pipe=null; try { pipe=ParcelFileDescriptor.createPipe(); AssetManager assets=getContext().getResources().getAssets(); new TransferTask(assets.open(uri.getLastPathSegment()), new AutoCloseOutputStream(pipe[1])).start(); } catch (IOException e) { Log.e(getClass().getSimpleName(), "Exception opening pipe", e); throw new FileNotFoundException("Could not open pipe for: " + uri.toString()); } return(pipe[0]); }

where the background thread does a typical stream-to-stream copy:

 static class TransferTask extends Thread { InputStream in; OutputStream out; TransferTask(InputStream in, OutputStream out) { this.in=in; this.out=out; } @Override public void run() { byte[] buf=new byte[1024]; int len; try { while ((len=in.read(buf)) > 0) { out.write(buf, 0, len); } in.close(); out.close(); } catch (IOException e) { Log.e(getClass().getSimpleName(), "Exception transferring file", e); } } }

However, MediaPlayer chokes:

10-16 13:33:13.203: E/MediaPlayer(3060): Unable to to create media player 10-16 13:33:13.203: D/MediaPlayer(3060): Couldn't open file on client side, trying server side 10-16 13:33:13.207: E/TransferTask(3060): Exception transferring file 10-16 13:33:13.207: E/TransferTask(3060): java.io.IOException: write failed: EPIPE (Broken pipe) 10-16 13:33:13.207: E/TransferTask(3060): at libcore.io.IoBridge.write(IoBridge.java:462) 10-16 13:33:13.207: E/TransferTask(3060): at java.io.FileOutputStream.write(FileOutputStream.java:187) 10-16 13:33:13.207: E/TransferTask(3060): at com.commonsware.android.audiolstream.PipeProvider$TransferTask.run(PipeProvider.java:120) 10-16 13:33:13.207: E/TransferTask(3060): Caused by: libcore.io.ErrnoException: write failed: EPIPE (Broken pipe) 10-16 13:33:13.207: E/TransferTask(3060): at libcore.io.Posix.writeBytes(Native Method) 10-16 13:33:13.207: E/TransferTask(3060): at libcore.io.Posix.write(Posix.java:178) 10-16 13:33:13.207: E/TransferTask(3060): at libcore.io.BlockGuardOs.write(BlockGuardOs.java:191) 10-16 13:33:13.207: E/TransferTask(3060): at libcore.io.IoBridge.write(IoBridge.java:457) 10-16 13:33:13.207: E/TransferTask(3060): ... 2 more 10-16 13:33:13.211: E/MediaPlayer(3060): Unable to to create media player 10-16 13:33:13.218: E/TransferTask(3060): Exception transferring file 10-16 13:33:13.218: E/TransferTask(3060): java.io.IOException: write failed: EPIPE (Broken pipe) 10-16 13:33:13.218: E/TransferTask(3060): at libcore.io.IoBridge.write(IoBridge.java:462) 10-16 13:33:13.218: E/TransferTask(3060): at java.io.FileOutputStream.write(FileOutputStream.java:187) 10-16 13:33:13.218: E/TransferTask(3060): at com.commonsware.android.audiolstream.PipeProvider$TransferTask.run(PipeProvider.java:120) 10-16 13:33:13.218: E/TransferTask(3060): Caused by: libcore.io.ErrnoException: write failed: EPIPE (Broken pipe) 10-16 13:33:13.218: E/TransferTask(3060): at libcore.io.Posix.writeBytes(Native Method) 10-16 13:33:13.218: E/TransferTask(3060): at libcore.io.Posix.write(Posix.java:178) 10-16 13:33:13.218: E/TransferTask(3060): at libcore.io.BlockGuardOs.write(BlockGuardOs.java:191) 10-16 13:33:13.218: E/TransferTask(3060): at libcore.io.IoBridge.write(IoBridge.java:457) 10-16 13:33:13.218: E/TransferTask(3060): ... 2 more

No, it is not a good practice for large applications, especially not if your static variables are mutable, as they are then effectively global variables, a code smell which Object Oriented Programming was supposed to "solve".

At the very least start by grouping your methods into smaller classes with associated functionality - the Util name indicates nothing about the purpose of your methods and smells of an incoherent class in itself.

Second, you should always consider if a method is better implemented as a (non-static) method on the same object where the data that is passed as argument(s) to the method lives.

Finally, if your application is quite large and/or complex, you can consider solutions such as an Inversion of Control container, which can reduce the dependency on global state. However, ASP.Net webforms is notoriously hard to integrate into such an environment, as the framework is very tightly coupled in itself.

39278406 0 Where do webpack assets go in an Angular 2 CLI project

Where should I place general, cross-component .css, .scss, .svg, .gif, etc. assets (e.g., theme resources) in an Angular CLI (webpack) project so both the development and production versions of my application work correctly without changes?

When I generate a new foo project with Angular CLI (angular-cli: 1.0.0-beta.11-webpack.8, node: 6.5.0, os: linux x64) using ng new foo --styles=scss, the following structure is created (with node_modules trimmed):

foo ├── angular-cli.json ├── config │ ├── karma.conf.js │ └── protractor.conf.js ├── e2e │ ├── app.e2e-spec.ts │ ├── app.po.ts │ └── tsconfig.json ├── node_modules ├── package.json ├── public ├── README.md ├── src │ ├── app │ │ ├── app.component.css │ │ ├── app.component.html │ │ ├── app.component.spec.ts │ │ ├── app.component.ts │ │ ├── app.module.ts │ │ ├── environments │ │ │ ├── environment.dev.ts │ │ │ ├── environment.prod.ts │ │ │ └── environment.ts │ │ ├── index.ts │ │ └── shared │ │ └── index.ts │ ├── favicon.ico │ ├── index.html │ ├── main.ts │ ├── polyfills.ts │ ├── test.ts │ ├── tsconfig.json │ └── typings.d.ts └── tslint.json

The public area seems reasonable but what about .scss files? The src/app/public seems reasonable as well, but what the right directory to allow the development and production versions to work correctly?

What should file references look like in HTML and SCSS files? Are they all relative paths based on source layout in SCSS files (e.g.@import '../scss/layout';) and absolute paths in HTML files (e.g., <link href="/assets/css/main.css" rel="stylesheet">)?

(This was originally a comment)

You seem to miss what the point of pseudo code is. Pseudo code is neither standardized nor somewhat defined. In general it is just a code-like representation of an algorithm, while maintaining a high level and readability. You can write pseudo code in whatever form you like. Even real Python code could be considered pseudo code. That being said, there are no thing disallowed in pseudo code; you can even write prose to explain something that happens. For example in the inner-most loop, you could just write “swap value1 and value2”.

This is approximately how I would transform your Python code into pseudo-code. I tend to leave out all language specific stuff and focus just on the actual algorithmic parts.

Input: list: Array of input numbers FOR j = 0 to length(list): FOR i = 0 to length(list)-1: if list[i] > list[i+1]: Swap list[i] and list[i+1] OUTPUT ordered list

So is it okay to use lists, tuples, dictionaries in a pseudocode, even if they are not common to all programming languages?

Absolutely! In more complex algorithms you will even find things like “Get minimum spanning tree for XY” which would be a whole different problem for which again multiple different solutions exist. Instead of specifying a specific solution you are keeping it open to the actual implementation which algorithm is to be used for that. It usually does not matter for the algorithm you are currently describing. Maybe later when you analyze your algorithm, you might mention things like “There are algorithms known for this who can do this in O(log n)” or something, so you just use that to continue.

You need to include the appropriate header for std::transform:

#include <algorithm>

You should also avoid using namespace std; in the global namespace in headers, you pollute the global namespace of any code that includes your header file.

See this post about using namespace std.

The construct you are looking for is called column_property. You could use a secondary mapper to actually replace the amount column. Are you sure you are not making things too difficult for yourself by not just storing the negative values in the database directly or giving the "corrected" column a different name?

from sqlalchemy.orm import mapper, column_property wrongmapper = sqlalchemy.orm.mapper(Transaction, Transaction.__table, non_primary = True, properties = {'amount': column_property(case([(Transaction.transfer_account_id==1, -1*Transaction.amount)], else_=Transaction.amount)}) Session.query(wrongmapper).filter(...)

You need to download the source packet of QT and compile it. It takes some time but is not really complicated.

Download and unzip QT source
Start a compiler shell (Visual Studio or mingw)
Execute configure in the QT source directory - add a flag for static compile here
execute make (Visual Studio nmake)
Wait some hours depending on the speed of your machine

First of all per K&R, the answer is yes.

At the conceptual level an array name is a ptr, they are absolutely the same thing, CONCEPTUALLY.

How a compiler implements an array is up to the compiler. This is the argument between those who say they are not the same thing and those who say they are.

A compiler could implement int a[5] as the pointer a to an unnamed chunk of storage that can contain 5 integers. But they don't. It is easier for a compiler writer to generate code for a simple array and then fudge on the pointer-ness of a.

Anyway, conceptually, the data area allocated by the int a[5]; statement can be referenced by the ptr a or it can be referenced by the pointer produced by the &a[0] statement.

24629115 0 How do you hide an expanded tableviews label when it is expanded? - IOS

I would like to hide an expanded tableviews label, when the cell is expanded and hide a button when it is collapsed. I have my cell implementation in another class, with the property of the label and the button in the header. The problem is that when I call these cell methods in the ExpandedViewController, the code goes into the method, but it won't change the properties behaviour. Could you possibly help me with this issue?

Thank you

if anybody else (like me) wants to try to get some jdbc information and you are using hibernate 4.x, you might try it that way:

import java.sql.Connection; import java.sql.SQLException; import org.hibernate.jdbc.Work; public class ConnectionInfo implements Work { public String dataBaseUrl; public String dataBaseProductName; public String driverName; @Override public void execute(Connection connection) throws SQLException { dataBaseUrl = connection.getMetaData().getURL(); dataBaseProductName = connection.getMetaData().getDatabaseProductName(); driverName = connection.getMetaData().getDriverName(); } public String getDataBaseProductName() { return dataBaseProductName; } public void setDataBaseProductName(String dataBaseProductName) { this.dataBaseProductName = dataBaseProductName; } public String getDataBaseUrl() { return dataBaseUrl; } public void setDataBaseUrl(String dataBaseUrl) { this.dataBaseUrl = dataBaseUrl; } public String getDriverName() { return driverName; } public void setDriverName(String driverName) { this.driverName = driverName; } }

Now you can retrieve your information like that:

// -- snip org.hibernate.ejb.EntityManagerImpl entityManagerImpl = (org.hibernate.ejb.EntityManagerImpl) genericDBAccess.getEntityManager().getDelegate(); Session session = entityManagerImpl.getSession(); connectionInfo = new ConnectionInfo(); session.doWork(connectionInfo); // -- snap

Hope that helps! I drove crazy finding this information....

I would use mocks, something like EasyMock, where you could mock the IOrderLogger, and then do something like this:

IOrderLogger log = EasyMock.createMock(IOrderLogger.class); log.Action(EasyMock.isA(LogAction.class)); EasyMock.expectLastCall();

This assumes that Action() returns void. This is a very Java-esque way of doing this. I'm not sure how far along the EasyMock.net has come.

I have a game start I've made, basically a oval, and I can move it anywhere with the keyboard key arrows.

I dont want to allow it to exit the frame, so I check if X is less than 0, return if higher than width return, same for y.

But it doesn't work for < width and > height, I can go to the right and bottom until it exits the frame, why?

This is the code, (I didnt use myHeight, myWidth I manually put the sizes, the sizes are 765, 500).

public void movePlayer(int x, int y) { System.out.println(myPlayer.getX()); if (x == 0) { if (y + myPlayer.getY() > 500 || y + myPlayer.getY() < 0) { return; } this.myPlayer.moveY(y); } else if (y == 0) { if (x + myPlayer.getX() > 765 || x + myPlayer.getX() < 0) { return; } this.myPlayer.moveX(x); } }

You only need virtual functions if you've set up an inheritance chain, and you want to override the default implementation of a function defined in the base class in a derived class.

The classic example is something as follows:

public class Animal { public virtual void Speak() { Console.WriteLine("..."); } } public class Dog : Animal { public override void Speak() { Console.WriteLine("Bow-wow"); } } public class Human : Animal { public override void Speak() { Console.WriteLine("Hello, how are you?"); } }

Both the Dog and Human classes inherit from the base Animal class, because they're both types of animals. But they both speak in very different ways, so they need to override the Speak function to provide their own unique implementation.

In certain circumstances, it can be beneficial to use the same pattern when designing your own classes because this enables polymorphism, which is essentially where different classes share a common interface and can be handled similarly by your code.

But I'll echo what others have suggested in the comments: learning object-oriented programming properly is not something you're going to be able to do by asking a few Stack Overflow questions. It's a complicated topic, and one well-worth investing your time as a developer learning. I highly advise picking up a book on object-oriented programming (and in particular, one written for the C# language) and going through the examples. OOP is a very powerful tool when used correctly, but can definitely become a hindrance when designed poorly!

7291047 0 Parsing Google Shopping Json Search Results

After a few weeks of trying numerous examples found here and it seems throughout the web, I'm stumped. I can retrieve the desired search results from Google Shopping just fine:

{ "items": [ { "product": { "title": "The Doctor's BrushPicks Toothpicks 250 Pack", "brand": "The Doctor's" } } ] }

My problem is that I have the data sitting in a string, how do I extract the two values (title,brand) in order to use them elsewhere in the program?

Here is the class in question: public class HttpExample extends Activity {

TextView httpStuff; DefaultHttpClient client; JSONObject json; final static String URL = "https://www.googleapis.com/shopping/search..."; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.httpex); httpStuff = (TextView) findViewById(R.id.tvHttp); client = new DefaultHttpClient(); new Read().execute("items"); } public JSONObject products(String upc) throws ClientProtocolException, IOException, JSONException { StringBuilder url = new StringBuilder(URL); url.append(upc); HttpGet get = new HttpGet(url.toString()); HttpResponse r = client.execute(get); int status = r.getStatusLine().getStatusCode(); if (status == 200) { HttpEntity e = r.getEntity(); String data = EntityUtils.toString(e); JSONObject timeline = new JSONObject(data); return timeline; } else { Toast.makeText(HttpExample.this, "error", Toast.LENGTH_SHORT); return null; } } public class Read extends AsyncTask<String, Integer, String> { @Override protected String doInBackground(String... params) { // TODO Auto-generated method stub try { String upc = ExportMenuActivity.upc; json = products(upc); return json.getString(params[0]); } catch (ClientProtocolException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } return null; } @Override protected void onPostExecute(String result){ httpStuff.setText(result); } }

}

The output of httpStuff.setText(result):

[{"product":{"brand":"The Doctor's, "title":"The Doctor's..."}}]

It depends on your CPU architecture how the communication happens, but it is usually via a special place in RAM, flash or the filesystem. No data structures are transferred, they would be meaningless to the kernel and the memory space will be different between the two. Uboot generally passes boot parameters like what type of hardware is present, what memory to use for something, or which type of mode to use for a specific driver. So yes, the kernel will re-initialize the hardware. The exception may be some of the low level CPU specifics which the kernel may expect uboot or a BIOS to have setup already.

Mocha is a traditional mocking library very much in the JMock mould. Stubba is a separate part of Mocha that allows mocking and stubbing of methods on real (non-mock) classes. It works by moving the method of interest to one side, adding a new stubbed version of the method which delegates to a traditional mock object. You can use this mock object to set up stubbed return values or set up expectations of methods to be called. After the test completes the stubbed version of the method is removed and replaced by the original.

18656040 0 How to prevent compiler from optimizing a load to variable that is never used

Intro: Im trying to quick hack fix old code and use __try MSVC extension to check if some ptr points to some legit memory or if *ptr will cause memory violation(if so I drop processing of this ptr). So I wrote something like:

bool checkIsPtrPointingToValidAddress(const void *ptr) { __try { auto cpy = *((int*)ptr); // force mem access... if ( (cpy ==42) && ((rand()+rand()+rand()+rand()+ rand()) == 1)) { FILE* pFile = fopen ("tempdata.dat","w"); //... by unlikely but possible action fputs (" ",pFile); fclose (pFile); } return true; } __except(1) { return false; } }

Thing is that my solution to force mem access seems weird, ugly, and as a bonus I'm not sure it is correct. Also please not I can't disable optimizations on the entire project, so that is not an option. And documentation for pragma optimize on MSDN sucks, aka it is not clear if "" disables all optimizations on the function.

First, classes, enums, and structs are terminated with ';' following the closing bracket (or scope). i.e.

struct St { .... };//<--- end of scope terminator

Next, what exactly are you trying to do following this bit? I'm guessing you're trying to define cases of it for use, but you're going about it entirely wrong. You need to have a member in the struct to set a value to, this can be an instance of the struct itself. Like this...

struct St { St element; };

Then you can set a value to the structs member, but in this particular instance you're probably gonna want some more data members for this sturct to be of any use...

struct St { char value; St element; St(char value, St element) // struct constructor : this->value(value), this->element(element){} // init list };

Now you can use the struct in the rest of your code simply by calling it by its identifier, which in this case would be 'St'.

Although, for what you're trying to achieve (I could be wrong) would be better suited for an enumerated value, which is (basically) a way of defining your own primitive, switchable, variable type. An example of where an enum would be useful would be something like...

const int MON = 0, TUE = 1, ....// rather than using "const int's" // define them as enumerations enum Day {MON,TUE,WED,THU,FRI,SAT,SUN}; /*each enum is assigned an integer ordinal that corresponds to its location as it is declared, so MON == 0, TUE == 1, and so on. You can alternatively assign your own value to it in an instance where the default ordinal would not be useful, for instance if you wanted them as characters...*/ enum Foo {Bar = 'B', Qat = 'Q', ...}; // or enum Ratings {PG13 = 13, R = 18, ...};

You would probably benefit from a resource like:

Yes, Visual Studio will ask every project in the solution to build at that point. But note asking to build and actually building are different things. Asking to build merely says, about to do something build again if you would like. MsBuild will then do a bit of checking under the hood and decide if it should actually build the underlying project.

If your project is actually building then there may be some other problem going on. Can you give us some more info like language, project type, etc ...

15766402 0 Won't recall variable from within boolean expression

I'm having trouble finding what exactly java is having trouble with when recalling a variable. I'm creating a simple chatbot and this is what I have so far:

public class Chatbot { public static void main(String[] args) { String name = JOptionPane.showInputDialog("Hi! How are you? My name is Chatbot! What is yours? "); if (name.compareTo("a")<0){ String city = JOptionPane.showInputDialog("Nice to meet you! Where are you from, "+name); } else { String city = JOptionPane.showInputDialog("Huh. That's a strange name. Where are you from,"+name); } if (!city.equals("Seattle")){ } } }

My problem is that java won't recognize the variable city within the if else statements and so says city is not resolved. How do I get java to recognize the objects within a boolean expression? What am I doing wrong?

This seems to be more related to the way I was including Espresso than it is a Dagger issue...

androidTestCompile ('com.google.android.apps.common.testing:espresso:1.1' ){ exclude group: 'com.squareup.dagger' }

Switching to Jake Wharton's "double-espresso" made the problem go away.

I am still not sure why that would cause a NoClassDefFoundError on that Dagger generated class.

27595996 0 Changing static content directory

I am trying to set the express.static path to something different based on a session variable. The relevant code is below.

app.use( '/', function(req, res, next ) { if ( req.session.loggedIn ) { console.log("loggedIn : " + req.session.loggedIn); app.use('/', express.static(__dirname + '/private')); next(); } else { console.log("not logged in."); app.use('/', express.static(__dirname + '/public')); next(); } });

When I start the application, I begin with not having req.session.loggedIn set. So it will use the static content in the /public directory (which contains an angular powered application for public users.) I then do a login (code below)

app.post('/login', function( req, res ) { req.session.loggedIn = true; var message = {}; message.success = true; message.text = "Logging you in..."; res.json(message); });

Which sets the req.session.loggedIn variable to be true. I then hit refresh on the page (and have tried hard refresh, and cache clear/refresh as well). The console.log tells me "loggedIn : true" as expected, however it does NOT load the static content from the /private directory. It instead continues to load from the /public directory.

Can anyone shed light on this issue?

After gathering more information I came accross an interesting architecture (I have found the idea on reddit but could not retrieve the url).

Your whole code should be sperated into independent apps (separation of concern) and you need to define 2 "project wide" apps (site and utils):

the site app can depend on any other app.
the utils app does not depend on other apps but other apps can depend on it.
the independent apps can only depend on utils.

11112006 0 jQuery Form plugin - how to prevent double submission?

There are several threads on this here at SO but I didn't find one that deals specifically with the awesome jQuery Form plugin which I use extensively in my app.

I want the user to be able to click 'submit' only once -- and disable the 'submit' button until Ajax has returned a JSON string on success.

My trial code goes something like this

$('#submit_button').live('click', function(e) { e.preventDefault(); var options = { type: 'post', dataType: 'json', beforeSubmit: function(){ $('#loading').show().fadeIn(); $('#submit_button').attr('disabled', 'disabled'); }, success: function(data) { if (data.success === 3) { $('#submit_button').hide(); $('#loading').hide(); $('#validation_message').html(data.message).fadeIn(); $('#submit_button').attr('enabled', 'enabled'); } } } $(this).closest('form').ajaxSubmit(options); });

But this piles up "enabled" and "disabled" attributes in the <button>.

<button class="button" id="submit_button" disabled="disabled" enabled="enabled"> Post </button>

Do you have any suggestions on how to get this to work?

4245046 0 Change background of title and header in pivot control

In my Phone 7 application, I'm using a pivot control. Now I'd like to change the background of its title and header area. How can I achieve this?

Is there an overall template for the pivot control that can be customized?

I've already tried to set the background of the grid containing the pivot control to the header color and then to set the background of each pivot item to the original background color. It looks good on first sight. But when you wipe the pivot item to the left to display the second item, an area colored in the header color appears between the two pivot items. So that approach is not working.

Furthermore I've tried to customize the template of the title and the header item. But these templates only cover the area of the text itself, not the whole header and template area.

To get a dynamic select from the appropriate table, you can use a dynamic SQL finder.

In this example, we select from a table named 'albums', and fabricate a column 'name' to hold the values. These will be returned in the 'Album' model object. Change any of these names to suit your needs.

Album.find_by_sql("SELECT DISTINCT SUBSTR(name,1,1) AS 'name' FROM albums ORDER BY 1")

Note that you can't use the Album model objects for anything except querying the 'name' field. This is because we've given this object a lobotomy by only populating the 'name' field - there's not even a valid 'id' field associated!

There are three alternatives for unsolvable hash collisions on open addressing hash tables:

Re-hash the entire table with a different hash function, and hope that no new unsolvable hash collisions occur.
Resize the table (with all operations that this might incur), to guarantee some more possible slots.
Keep a separate list for unsolvable hash collisions.

None of those options are good.

What you should do is to carefully chose your probing method in combination with the hash table size. If your table size was odd, with the same constant step, you would not run in this problem while there was still space in the table.

Popular combinations include quadratic probing with a prime-sized hash table, that guarantees insertion success if the table is less than half-full, and quadratic probing with triangular numbers and power of 2 hash table, that guarantees insertion if the table isn't full. Power of 2 sized hash tables have many advantages, the only defect being that they are unforgiving on the quality of the hash algorithm.

Since you have 4 columns including the primary key column, you have to provide data for all four columns. Hence the first one is IDENTITY column, you can provide any value for that column as this column value will not be used but ommitted.

In your case if you provide data like it will work:

1 11 11 11 1 22 22 22 1 33 55 66

I have checked this and found it works. If you don't have any option to alter the csv file then you can create a staging table without the identity column and perform the bulk insert operation. After that, you can move data from your staging to target table by performing INSERT INTO command. I hope this might solve your problem.

29889112 0 where the behavior of private and static method is different from only private method

As for my understanding:

When a method is static it is

early bind
can call with the name of class even before no object is created
can call only static member inside it.

I never found any other behaviour of static either at compile time or runtime. Is there any?

When a method is private it is

also early bind
can only call inside call so can call directly without object.

For example the hugeCapacity() method in the ArrayList class.

private static final int DEFAULT_CAPACITY = 10; private static int hugeCapacity(int minCapacity) { if (minCapacity < 0) // overflow throw new OutOfMemoryError(); return (minCapacity > MAX_ARRAY_SIZE) ? Integer.MAX_VALUE : MAX_ARRAY_SIZE; }

Since there are in Java private+static method exist. Why their need occurs. Is it for restriction purpose, to restrict access of non static variables inside a method?

self when used as first method argument, is a shorthand for self: Self – there are also &self which equals self: &Self and &mut self which equals self: &mut Self.

Self in method arguments is syntactic sugar for the receiving type of the method (i.e. the type whose impl this method is in. This also allows for generic types without too much repetition.

I have an internationalized product. No translation has been done, but the strings are all externalized, so if we had a desire to ship the product localized for a specific country we could get the files translated, have the product tested, and ship it for use natively in that country.

For now the fully internationalized product is all english, but the coding is all done. If someone were to attempt to check in code that was not proper the reviewer could rightly reject it on the grounds that it is not internationalized, and would render the product unable to be fully localized.

But since no testing has been done then it really is not internationalized fully yet ...

You would have to use javascript and/or jquery to dynamically add the css class that has the animation to the desired element after the page has been loaded. We can do this with the $document.ready event in jquery.

$(document).ready(function(){ $('css selector').addClass('class-that-has-animation-binding'). });

That is how he is doing it on the main site if you view is source code.

One way would be to:

a) Copy your JSON to Clipboard (CTRL+C)

b) On a Visual Studio class, click on EDIT-> Paste Special -> Paste JSON as classes. This will create the classes equivalent of your JSON for you. Your main object would be named as "Rootobject" and you can change this to whatever name you want.

c) Add System.Web.Extensions to your references

d) You can convert your JSON to class like so:

JavaScriptSerializer serializer = new JavaScriptSerializer(); Rootobject rootObject = serializer.Deserialize<Rootobject>(JsonString);

Where JsonString is your API output.

if ($(this).closest('td').next().find('input[type=checkbox]').is(":checked")) { // Do something }

Live Example:

$(document).on('click', '.exempt', function() { if ($(this).closest('td').next().find("input[type=checkbox]:checked").length) { alert("yes, it's checked"); } else { alert("no, it isn't"); } });

The request which leads to this method being called need to pass through the Spring Security filter chain, otherwise there will be no security context available when the permissions are checked.

Without seeing the rest of the stacktrace, I can't say 100%, but it looks like that's what's happening here, given the exception you are seeing (you should find similar issues if you search for the error message).

So you need to make sure all the requests you want secured are handled by the security filter chain, and also that your filter chain is properly configured (which it should be automatically if you're using the namespace).

About Callback, you have initialized callback and in your case you don't have to pass callback as function parameter. Try use following:

async.series([ /*some functions*/ function() { setTimeout(callback, 2000); loop(); } ])

I am getting correct number with the following config:-

and yes, your JSON is incorrect.. It should be :-

{ "orders" : { "order" :[ { "id" : "4358153416", "fulfillment" : { "tracking_number" : "915", "line-items" : { "id" : "8367362760" } } }] } }

You have missed [ after order

You shouldn't be mocking at that level. Basically the idea is that you have interfaces that acts as a facade on database and ORM operations.

interface IFetchUsers { UserList GetAll(); User GetById(int id); } interface ICalculateDebt { float GetDebt(int accountId); } interface IPersistOrder { void Save(Order order); }

(forgive syntax errors, it's been a long time since I've done Java.)

These are injected via the constructor into your other classes and become trivial to mock, or even stub.

Then, for actual db code you just implement these interfaces. You can even put all implementations in a single class.

And that's it. No need to get fancy, but if you do want to get into fancier versions of this look into the repository design pattern (though I would argue that its not really necessary if using a good ORM).

6063744 0 Ajax client for a CXF service

I'm new to CXF, and I was trying to implement a CFX client in Ajax. I had already implemented a client in Java but now I need to implement a client-side application to access CXF. I'm not even sure that it's possible to do that (Accessing CXF directly from client-side). If it's possible then kindly direct me to some ajax code. If not, then please help me with your ideas for a web-based CFX client. Thanks

761352 0 Django QuerySet order

I am new to both django and python but I am beginning to get a grasp on things. I think.

I have this problem and I can not seem to find an answer to it. (Though I assume it is really simple and the limiting factors are my google skills and lack of python/django knowledge)

The scenario:

a user can opt in to recieve temporary job openings at any number of stores he or she chooses.

I would like to present a list of upcoming job openings (StoreEvents) sorted by the DateField only.

Example: Store A - 2009-04-20 Store B - 2009-04-22 Store A - 2009-04-23

Atm I am stuck with presenting the data first sorted by store then by date since I am obviously accessing the StoreEvents through the Store model.

Example: Store A - 2009-04-20 Store A - 2009-04-23 Store B - 2009-04-22

So my question is: Is it possible to create a QuerySet that looks like the first example and how do I do it?

Examples of related models included:

class Store(models.Model): class StoreEvent(models.Model): info = models.TextField() date = models.DateField() store = models.ForeignKey(Store, related_name='events') class UserStore(models.Model): user = models.ForeignKey(User, related_name='stores') store = models.ForeignKey(Store, related_name='available_staff')

Edit:

The following SQL does the trick but I still can't figure out how to do it in django:

SELECT * FROM store_storeevent WHERE store_id IN ( SELECT store_id FROM profile_userstore WHERE user_id =1 ) ORDER BY date

With validation efficiency is not usually the concern. There are two types of validation that you should be concerned with:

Input validation, e.g. will what the user is sending to the server malicious and intended to break/break into my application
Business validation, which should happen in your business logic, and should be about maintaining valid, consistent values.

Skipping over either of these is a very very good way to end up with either a hacked or badly broken application.

If you're using ASP.net there are a plethora of libraries (mostly from Microsoft) to do the former, Anti-XSS lib etc.

The latter would be most efficiently preformed in your shared business logic in the entities themselves. E.G your user entity should not allow an age of -1.

11149365 0 trouble using lambda expressions and auto keyword in c++

I'm trying to learn how to use lambda expressions in C++.

I tried this simple bit of code but I get compile errors:

int main() { vector<int> vec; for(int i = 1; i<10; i++) { vec.push_back(i); } for_each(vec.begin(),vec.end(),[](int n){cout << n << " ";}); cout << endl; }

Errors:

 forEachTests.cpp:20:61: error: no matching function for call to'for_each(std::vector<int>::iterator, std::vector<int>::iterator, main()::<lambda(int)>)' forEachTests.cpp:20:61: note: candidate is: c:\mingw\bin\../lib/gcc/mingw32/4.6.2/include/c++/bits/stl_algo.h:4373:5: note:template<class _IIter, class _Funct> _Funct std::for_each(_IIter, _IIter, _Funct)

I also tried making the lambda expression an auto variable but I got a different set of errors.

Here is the code:

int main() { vector<int> vec; for(int i = 1; i<10; i++) { vec.push_back(i); } auto print = [](int n){cout << n << " ";}; for_each(vec.begin(),vec.end(),print); cout << endl; }

This gave me the following errors:

 forEachTests.cpp: In function 'int main()': forEachTests.cpp:20:7: error: 'print' does not name a type forEachTests.cpp:22:33: error: 'print' was not declared in this scope

I'm assuming these are problems with my compiler but I am not quite sure. I just installed MinGW and it appears to be using gcc 4.6.2.

You can use position: absolute and transform: translate()

nav { position: relative; background: #2196F3; height: 50px; } .mdl-layout-title { position: absolute; left: 50%; top: 50%; transform: translate(-50%, -50%); }

<nav> <span class="mdl-layout-title navbar">Title</span> </nav>

The answer I found is that Haml doesn't play well with javascript. If you are going to have a js file it should be an Erb file. So rather that your_file.js.haml it should be your_file.js.erb.

I use a ClientRowTemplate to achieve something similar to the above.

Look at this documentation: http://demos.telerik.com/aspnet-mvc/grid/rowtemplate

Basically I define my Row template in a partial view then I render the partial like this:

@(Html.Kendo().Grid(Model).Name("usersManageGrid") .Columns(columns => { columns.Bound(c => c.LoginId).Visible(false); columns.Bound(c => c.FullName).Title("Name").Width(120); columns.Bound(c => c.Email).Title("Username"); }).ClientRowTemplate(Html.Partial("_TestPartial").ToHtmlString()))

You can still specify and bind to other columns like the documentation shows. You can also pass in your sub view model if you wish as normal;

.ClientRowTemplate(Html.Partial("_TestPartial",x.SubViewModel).ToHtmlString())

The partial view which contains the row template looks like this:

<tr data-uid='#: LoginId #'> <td> <span class='description'><b>Name</b> : #: FullName# </span> </td> <td> @Html.Partial("_Test2Partial") </td> </tr>

Then you will see I render another partial view for the second column which simply has this in it:

<span style="color:purple;"><b>Email</b> : #: Email# </span>

The end result looks like this:

3240026 0 PrincipalPermission vs. web.config for page access controls

I currently have my access permissions in web.config:

 <location path="Account"> <system.web> <authorization> <allow users="?"/> </authorization> </system.web> </location> ...

I don't like this for two reasons:

web.config becomes a mess as my website builds up
I'm not sure it's good security to keep the web page access rule so separated from the page itself. After all, I edit aspx/c# files most of the day and not web.config, so things tend to slip.
This is a very weird one... I just added ASP.NET4 routing, which changes the URLs. So, all of a sudden my web.config permissions are no longer valid! Similar to point #2 above.

I was thinking it would be better to just use PrincipalPermission as security attributes for the classes/c# files involved in each aspx. My question:

Is this done by anyone, or is it a bad ideas?
More importantly... My PrincipalPermission attribute generates an exception (good) but does not redirect users back to the logon page (bad). Can this be fixed?

As mentioned in the comments, the problem is your response redirects to another url, your HttpUrlConnection must handle redirects. See this on how to do it.

You can skip it with case ... when ... else like you figured out by yourself:

... ||case when A.NEXTQUESTIONID is not null then 'NextQuestionID = '||A.NEXTQUESTIONID||',' else '' end || ...

You can also use the nvl2 function for a shorter solution:

... || nvl2(A.NEXTQUESTIONID, 'NextQuestionID = '||A.NEXTQUESTIONID||',', '') || ...

30643331 0 How can I wait for an application launched by another application launched by my application Qt/C++

I'm creating a Windows Add/Remove Programs application in Qt 5.4 and I'm becaming crazy to solve a little "puzzle":

My application (APP_0) runs another application (APP_1) and waits for this APP_1 until it terminates.

APP_1 is an uninstaller (i.e. uninstall.exe) and I've not the source code of the APP_1, just of my Qt APP_0.

APP_1, instead of doing the uninstall job, it simply copies itself somewhere in the filesystem (I saw as Au_.exe but other apps could use different names and locations), runs this copy of itself (APP_2) and terminates.

The APP_2 has a GUI and the job I'm waiting for (uninstall) is demanded to the final user of the running APP_2.

In this situation my application (APP_0) stops waiting for APP_1 pratically immediately (because it launches APP_1 and waits for APP_1). But to work properly, obviously, I need to know instead when APP_2 is terminated...

So the question is: is there a way (using some techniques (hooking?)) to know if and when APP_2 terminates?

Note: Consider that the standard Windows Add/Remove Programs utility does the job successfully (it seems it waits for APP_2). You can test this, for example, installing Adobe Digital Edition. Its uninstaller (uninstall.exe) copies itself into a new folder in the User_Local_Temp folder as Au_.exe, runs it and terminates. But the OS utility successfully waits for Au_.exe and only after it terminates refreshes the list of installed programs.

If this kind of technique (uninstall.exe copies itself somewhere ALWAYS with THE SAME name (Au_.exe) ) the problem could be resolved, obviously, very simply. But I don't think that the name of the copied uninstaller is always the same and also I don't like to assume things I'm not sure are real.

Many thanks in advance

21487685 0 How can I read multiple cookies with Perl's CGI.pm?

I am using CGI.pm to write out cookies. Now during the course of the user using my site, other cookies are added to the "test.com" cookie set, (as shown in the broswer history)

But now I want to log the user out, and "clean" the PC. Since I don't know what scripts the user has used, I can't foresee what cookies would be on the PC.

In short, it there a way to read all the cookies for "test.com" back into a script so I can then print them out again with a 1s duration, (effectively 'deleting' them) ** I know you can read the cookie back in with $xyz=cookie('$name') ... but how can I create the array holding the $name variable so I can loop through it? The script will also run on "test.com", so the cross site policy is not an issue

+++++ brian d foy added a partial answer below. So this how I envisage the code might be strung together.

use CGI::Cookie; %cookies = CGI::Cookie->fetch; for (keys %cookies) { $del_cookie.="cookie(-NAME=>'$cookies[$_]',-PATH=>'/',-EXPIRES=>'+1s');"; } print header(-cookie=>[$del_cookie]);

I wondered how the script would recognise the domain. Appears the script is intelligent enough to only load the cookies for the domain for which the script is being executed on. (Now I've just got to find out why Firefox doesn't delete expired cookies!! Just found some listed that expired 29th - 31st Jan within my test domain, and at first wondered why they didn't appear in my cookie list!)

You don't need an SqlDataAdapter and all the infrastructure required to work with if you just have a single value returned by your Stored Procedure. Just use ExecuteScalar

int count = 0; using (var con = new SqlConnection(connectionString)) using (var cmd = new SqlCommand("RunAStoredProc", con)) { cmd.CommandType = CommandType.StoredProcedure; count = (int)cmd.ExecuteScalar(); } Console.WriteLine(count); Console.ReadKey();

However if your really want to use an adapter and a dataset then you can find the result of your query reading the value from the first row and first column from the returned table

int count = Convert.ToInt32(table1.Rows[0][0]);

or even (without declaring the table1 variable)

int count = Convert.ToInt32(ds.Tables[0].Rows[0][0]);

To discover the difference between the result of the first select statement and the count of rows returned in the second select statement you could write

int allStudents = Convert.ToInt32(ds.Tables[0].Rows[0][0]); int enrolledStudents = ds.Tables[1].Rows.Count; int notEnrolledStudents = allStudents - enrolledStudents;

When I try

disk1 = @server.disks.build

On client side it gave error

There are likely to be several "problems", or ways to make it faster. I wouldn't call them "bottlenecks" because often they are not localized. Typically they are perfectly good code - it was just never supposed that they would be on the "critical path".

Suppose the problems, when fixed, would save these percentages:

enter image description here

Just finding one of them would give you a certain amount of speedup. Like if you just find A, that would give you a speedup of 1/(1-0.3) = 1.43 or 43%. If you did that, you could, like most people, be happy and stop. However, if you continued and also found B, your total speedup would be 1/(1-0.51) = 2.04 or 104%. That's a lot more than 43%, even though B was smaller than A. Fixing C brings you up to 2.92 times faster, and D brings you to 4.2 times faster.

What? Fixing smaller problems has higher payoff? They can, because speedup factors compound. Fixing A and B in that order gives you 1.43 * 1.43 = 2.04. If you happen to fix them in the opposite order you get 1.27 * 1.61 = 2.04

Each time you fix something, the other issues become larger, percentage-wise and easier to find, and the speedups accumulate like a high-yield investment. By the time you fix A, B, C, D, and E, the one left is F and it isn't 5%, it's 30%. Fix all of them, and now you are 8.5 times faster! However, if you miss one, like D, because your profiling tool fails to expose it, you are only 4.5 times faster.

That's the price you pay for not finding a problem.

That's why I rely on a manual technique, because, relative to profilers, it finds all problems they find, and it finds ones they don't. Profilers are often concerned with peripheral issues, like accuracy of measurement, which doesn't help to find problems. If you're wondering why, here's the math.

Assuming it's a business site:

What's your target market? How long do you expect until you release a working version of your website? If current trends continue, what will be IE6's market share by then? How much profit/value will those users bring? How much will it cost to support those additional users? Unless the costs are far below the profit, then don't bother. Otherwise, it might be a good idea.

If it's not a for-profit site(hobby, for instance), then you probably shouldn't bother, unless there's a really significant IE6 market share in your target market.

By the way, remember to use graceful degradation when possible and use feature detection instead of browser detection. Finally, avoid blocking IE6 users and instead just display a warning saying the website is untested in their browser and suggesting an update(this last piece of advice only applies if you don't plan to support IE6)

Once a program goes out of memory it can be hard for it to recover. You need to think carefully about how to try and clean up when that happens. For example, in your saveImageToExternalStorage, it doesn't clean up the fOut if an exception occurs inside your try/catch. So you should do things like put

OutputStream fOut = null;

outside the try/catch, and then close it in a finally block of the try/catch. And pay attention to the possibility of further exceptions in the catch of finally blocks.

The preferred way to interact with a db when using an ORM is not to use queries but to use objects that correspond to the tables you are manipulating, typically in conjunction with the session object. SELECT queries become get() or find() calls in some ORMs, query() calls in others. INSERT becomes creating a new object of the type you want (and maybe explicitly adding it, eg session.add() in sqlalchemy). UPDATE becomes editing such an object, and DELETE becomes deleting an object (eg. session.delete() ). The ORM is meant to handle the hard work of translating these operations into SQL for you.

Have you read the tutorial?

I don't want to create B class object

Add a constructor or factory method which doesn't require a B.

public A(B b){ this(b.getList()); } /* package local */ A(List<String> list){ this.list = list; }

By making the constructor package local it can be accessed by unit tests in the same package.

How to test someMethod without calling constructor of A?

You can use

A a = theUnsafe.allocateInstance(A.class);

but this is not recommended unless you have no other option e.g. deserialization.

If your static lib is another project in the same solution as the project that links to the lib, then you need to set a dependency between the two projects so that the build process will build the lib first and the other project second.

To do this, right-click on the Solution abd choose "Project dependencies" from the pop-up menu.

You can create a class no-gutter for your row and remove the margin/padding that's added by bootstrap, like suggested in this post:

.row.no-gutter { margin-left: 0; margin-right: 0; } .row.no-gutter [class*='col-']:not(:first-child), .row.no-gutter [class*='col-']:not(:last-child) { padding-right: 0; padding-left: 0; } .row > div { background: lightgrey; border: 1px solid; }

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/> <div class="row no-gutter"> <div class="col-md-2"> 1 </div> <div class="col-md-10"> 2 </div> </div>

I've set a gray background and a border for demonstration purposes. Watch the result in fullscreen to see, that there is no space anymore between the columns. More information about the predefined margin and padding in Bootstrap can be found here.

The Java final keyword is used in the Java programming language under different conditions and has different implications. For example:

To declare a constant variable,
To declare a constant method parameter.
1. A variable declared as final must have an initialization prior to its usage. This variable cannot be assigned a new value such as (a = b). But if the variable is not of primitive type then its properties can be set using the set methods or any other public fields. This means that the object instance reference cannot be changed but the properties of the object instance can be changed as long as they themselves are not declared final.
2. To prohibit the parameter being modified in the method where it is being used.

At each terminal node (leaf) you are printing )s for all parents; you should only do so for consecutive right-side parents.

I suggest renaming parents to depth and adding a right_depth parameter.

Edit: after playing around with it a bit, I decided it was better to delegate it to the tree:

class Node: INDENT = " " __slots__ = ["lhs", "word_label", "left_child", "right_child"] def __init__(self, lhs, *args): self.lhs = lhs num_args = len(args) if num_args == 1: self.word_label = args[0] self.left_child = None self.right_child = None elif num_args == 2: self.word_label = None self.left_child = args[0] self.right_child = args[1] else: raise ValueError("should have one arg (word_label: str) or two args (left: Node and right: Node)") def is_terminal(self): return self.word_label is not None def tree_str(self, depth=0, indent=None): if indent is None: indent = self.INDENT if self.is_terminal(): return "\n{}({} '{}' )".format( indent * depth, self.lhs, self.word_label ) else: return "\n{}( {}{}{} )".format( indent * depth, self.lhs, self.left_child .tree_str(depth + 1, indent), self.right_child.tree_str(depth + 1, indent) ) def __str__(self): return self.tree_str()

then some syntactic helpers,

def make_leaf_type(name): def fn(x): return Node(name, x) fn.__name__ = name return fn for leaf_type in ("VB", "DT", "NNS", "IN", "NP_NNP", "TO", "NN", "PUNC"): locals()[leaf_type] = make_leaf_type(leaf_type) def make_node_type(name): def fn(l, r): return Node(name, l, r) fn.__name__ = name return fn for node_type in ("TOP", "S_VP", "NP", "PP"): locals()[node_type] = make_node_type(node_type)

so I can create the tree,

tree = \ TOP( S_VP( VB('List'), NP( NP( DT('the'), NNS('flights') ), PP( PP( IN('from'), NP_NNP('Baltimore') ), PP( TO('to'), NP( NP_NNP('Seattle'), NP( NP( DT('that'), NN('stop') ), PP( IN('in'), NP_NNP('Minneapolis') ) ) ) ) ) ) ), PUNC('.') )

which then prints like

>>> print(tree) ( TOP ( S_VP (VB 'List' ) ( NP ( NP (DT 'the' ) (NNS 'flights' ) ) ( PP ( PP (IN 'from' ) (NP_NNP 'Baltimore' ) ) ( PP (TO 'to' ) ( NP (NP_NNP 'Seattle' ) ( NP ( NP (DT 'that' ) (NN 'stop' ) ) ( PP (IN 'in' ) (NP_NNP 'Minneapolis' ) ) ) ) ) ) ) ) (PUNC '.' ) )

which I believe is actually what is desired.

28113856 0 'while' statement cannot complete without throwing an exception - Android

With this method I'm updating TextView every second.

 private void UpdatingTime(final String endTime, final long diffInDays) { new Thread(new Runnable() { @Override public void run() { while (true) { try { Thread.sleep(ONE_SECOND); mHandler.post(new Runnable() { @Override public void run() { // Updating time every second long diffInHours = Methodes.diffInHours(endTime, diffInDays); long diffInMinutes = Methodes.diffInMinutes(endTime, diffInDays, diffInHours); long diffInSeconds = Methodes.diffInSeconds(endTime, diffInDays, diffInHours, diffInMinutes); tvTime2.setText(addZeroInFront(diffInHours) + ":" + addZeroInFront(diffInMinutes) + ":" + addZeroInFront(diffInSeconds)); } private String addZeroInFront(long diffInHours) { String s = "" + diffInHours; if (s.length() == 1) { String temp = s; s = "0" + temp; } return s; } }); } catch (Exception e) { e.printStackTrace(); } } } }).start(); } }

This method is working perfect. But I got this warning:

'while' statement cannot complete without throwing an exception.

Reports for, while, or do statements which can only exit by throwing an exception. While such statements may be correct, they are often a symptom of coding errors.

I hate warnings and I want to fix it. How can i fix this warning, or there is a better solution for this infinite loop...?

An IntentService runs in the background on a seperate Thread so anything done in the service will not effect the UI. BUT once the service finishes doing what it is suppose to, the service terminates itself.

A service also does stuff in the background BUT on the UI thread so if you have any time consuming things that need to be done it will hold up the UI. this also runs until you tell it to stop for the most part.

If you are using alarms to trigger everything I would say the IntentService is fine.

26539171 0 Difference between interface-abstract (not duplicate)

I want to know the difference between the two codes. I have a interface: lets say :

public interface iaminterface { void m1(); void m2(); void m3(); }

First Code :

public abstract class iamabstract implements iaminterface { public void m1(){} public abstract void m2(); // abstract method .So i need to override this in the subclasses. } public class car extends iamabstract { public void m2(){} public void m3(){} } public class train extends iamabstract { public void m2() {} public void m3() {} }

This code will compile successfully. But this code is same as writing :

Second Code:

 public abstract class iamabstract implements iaminterface { public void m1(){} } public class car extends iamabstract { public void m2(){} public void m3(){} } public class train extends iamabstract { public void m2() {} public void m3() {} }

I don't understand the difference in the two codes. Both codes will function in a similar way. One has a abstract method and another does not have a abstract method, so we need to implement the unimplemented methods of the interface. So , what's the use of writing the method m2() as abstract in the first code. ?

Use redirect_to with status 303

def destroy @task = Task.find(params[:id]) @task.destroy redirect_to :action => :index, status: 303 end

redirect_to documentation says:

http://api.rubyonrails.org/classes/ActionController/Redirecting.html

If you are using XHR requests other than GET or POST and redirecting after the request then some browsers will follow the redirect using the original request method. This may lead to undesirable behavior such as a double DELETE. To work around this you can return a 303 See Other status code which will be followed using a GET request.

The spacing is intentional and cannot be changed (without custom drawing the entire thing, which is not so easy in managed code), as WinMo 6.5 and later supposedly moved toward more "finger friendly" UIs.

I realize the link is for a ListView, but the TreeView in CE also supports custom drawing in the same way, and that link is the only custom drawn anything I've seen for the CF.

The line

while ((nextLine = br.readNext()) != null) {

takes advantage of the fact that an "assignment" is also an "expression" that has a value - the assigned value.

So the line, reading from inside the parentheses out, does the following:

Calls readNext() for the object br;
Assigns the result of the call to nextLine;
Tests the value assigned for null;
If it is null, it jumps past the body of the while loop, to 7.;
If it is not null, it executes the body of the while loop;
It then goes back to 1. again.
It continues the program.

This is a very interesting scenario. While in general, we can change any method which is returning void to return anything else without much impact, main method is a special case.

In earlier programming languages, the return from main method was supposed to return exit values to the OS or calling environment.

But in case of Java (where multi-threading concept case into picture), returning a value from main method would not be right, as the main method returns to JVM instead of OS. JVM then finishes other threads e.g. deamon threads (if any) and performs other exit tasks before exit to OS.

Hence allowing main method to return, would have lead to a false expectation with the developers. hence it is not allowed.

If time isn't an issue implementing OAuth security may be useful. OAuth uses a public key, and also a secret. The mess is hashed (in most cases) and the server will use the public key + it's copy of the secret to do the same hashing and make sure its result matches the requests.

The benefit is you wouldn't need to use HTTPS or POST. Get* REST api methods should be using the HTTP GET method (I'm not sure if being RESTful is your goal, just thought I would point that out). I agree with Mr. Pang, use http://www.business.com/employees. The query string could contain the list of department ids.

For your case the service call wouldn't have the 'accessKey' argument, rather it would become the public key (I imagine) and be used in either the headers, query string, or as a POST param.

Store the questions and a counter to store which question has been asked in $_SESSION['questions']. Use the counter (also stored in the $_SESSION) to figure out what the next question is and increment it after each submit.

To do this check after session_start(); if $_SESSION['questions'] is set. If not get your questions and store them into $_SESSION['questions] and set the counter to 0.

Instead of the foreach() you access your questions by $_SESSION['questions'][$_SESSION['counter']] but do not forget to increase the counter each time.

Sample code:

The part to set set / get the questions and increase the counter:

session_start(); if(!isset($_SESSION['questions'])) { $query = "SELECT * FROM question_table"; $statement = $db->prepare($query); $statement->execute(); $question = $statement->fetchall(); $statement->closeCursor(); $_SESSION['questions'] = $question; $_SESSION['counter'] = 0; } if (isset($_POST["submit"])){ // DO YOUR STUFF $_SESSION['counter']++; } ?>

The part the output the question:

<?php $question = $_SESSION['questions'][$_SESSION['counter']]; if(empty($question)) { // FINISHED ALL QUESTIONS } else { ?> <form action="QuestionAndOption.php" method="POST"> Question <?php echo $_SESSION['counter'] . ": " . $question["Question"]; ?><br> A: <input type="radio" name="option" value="OptionA"> <?php echo $question["OptionA"]; ?><br> B: <input type="radio" name="option" value="OptionB"> <?php echo $question["OptionB"]; ?><br> C: <input type="radio" name="option" value="OptionC"> <?php echo $question["OptionC"]; ?><br> D: <input type="radio" name="option" value="OptionD"> <?php echo $question["OptionD"]; ?><br> <button name="submit" type="submit">Submit</button> </form> <?php } // if close ?>

You can't do that. You need to setup a delegate protocol. See This tutorial and search down for the words "new delegate" and it will explain how that is done. That is the design pattern you need to use. There are several steps involved so follow closely. It is worth learning. Delegate protocols are common in iPhone Apps.

In a current project I created a delegate protocol to communicate between two controller: SelectNoteViewController (Select) and EditNoteViewController (Edit). The basic idea is that Select is used to select from a list of notes and Edit is used to edit those notes. Now, I need Edit to have access back into the data and methods kept by Select because I have buttons in edit to call up the previous or next note from the list which is managed by Select so I implement a delegate protocol. Select is a delegate for Edit. That means Select does things for Edit. Here is the essential code.

SelectNoteViewController.h:

// this next statement is need to inform Select of the protocols defined in Edit #import "EditNoteViewController.h" // STEP 1 @interface SelectNoteViewController : UITableViewController <EditNoteViewControllerDelegate> { ... // STEP 2: this says Select implements the protocol I created ... // STEP 3: EditNoteViewController Delegate Methods - these are the methods in the protocol - (Notes *)selectPreviousNote; - (Notes *)selectNextNote;

SelectNoteViewController.m:

// STEP 4: the protocol methods are implemented - (Notes *)selectPreviousNote { if (isPreviousToSelectedNote) { NSIndexPath *indexPath, *previousIndexPath; indexPath = [self.tableView indexPathForSelectedRow]; previousIndexPath = [NSIndexPath indexPathForRow:indexPath.row+1 inSection:0]; // update the selected row self.selectedNote = [self.fetchedResultsController objectAtIndexPath:previousIndexPath]; [self.tableView selectRowAtIndexPath:previousIndexPath animated:NO scrollPosition:UITableViewScrollPositionMiddle]; [self setPreviousNote]; [self setNextNote]; } return selectedNote; } - (Notes *)selectNextNote { if (isNextToSelectedNote) { NSIndexPath *indexPath, *nextIndexPath; indexPath = [self.tableView indexPathForSelectedRow]; nextIndexPath = [NSIndexPath indexPathForRow:indexPath.row-1 inSection:0]; // update the selected row self.selectedNote = [self.fetchedResultsController objectAtIndexPath:nextIndexPath]; [self.tableView selectRowAtIndexPath:nextIndexPath animated:NO scrollPosition:UITableViewScrollPositionMiddle]; [self setPreviousNote]; [self setNextNote]; } return selectedNote; } ... ... if ([[segue identifier] isEqualToString:@"editNote"]) { // STEP 5: this is where Edit is told that its delegate is Select [[segue destinationViewController] setEditNoteViewControllerDelegate:self]; // STEP 5

Select now has the structure to do be a delegate for Edit. Now Edit needs to define the protocol on its end that it is going to use to get to those methods in Select.

EditNoteViewController.h

#import ... // put protocol after import statements // STEP 6 @protocol EditNoteViewControllerDelegate <NSObject> - (Notes *)selectPreviousNote; - (Notes *)selectNextNote; @end @interface ... // STEP7: Edit needs a property to tell it who the delegate is - it was set back in Select.m @property (weak) id <EditNoteViewControllerDelegate> editNoteViewControllerDelegate;

EditNoteViewController.m

// STEP 8: the property is synthesized @synthesize editNoteViewControllerDelegate; ... // STEP 9: now when any method needs to call selectPreviousNote or selectNext Note it does it like this: selectedNote = [self.editNoteViewControllerDelegate selectPreviousNote]; // or selectedNote = [self.editNoteViewControllerDelegate selectNextNote];

That is it. Of course the protocol methods are like and other method and they can be passed parameters which what you need to do to pass data back which was your question in the first place. As a side note, see that I can pass data from Select to Edit without a protocol by creating properties in Edit and setting those properties in the prepareForSegue method of Select. Doing so gives me one shot to set some parameters when Edit is instantiated. My use of a the delegate protocol goes back to Select and has it pass another note (previous or next) to Edit. I hope that helps. You can see there are several steps to creating a delegate protocol. I numbered them 1-9. If the data is not making it back, I usually find I forgot one of the steps.

You can get rid of that kernel loop to calculate D with this bsxfun based vectorized approach -

D = squeeze(sum(bsxfun(@min,A,permute(B,[3 2 1])),2))

Or avoid squeeze with this modification -

D = sum(bsxfun(@min,permute(A,[1 3 2]),permute(B,[3 1 2])),3)

If the calculations of D involve max instead of min, just replace @min with @max there.

Explanation: The way bsxfun works is that it does expansion on singleton dimensions and performs the operation as listed with @ inside its call. Now, this expansion is basically how one achieves vectorized solutions that replace for-loops. By singleton dimensions in arrays, we mean dimensions of 1 in them.

In many cases, singleton dimensions aren't already present and for vectorization with bsxfun, we need to create singleton dimensions. One of the tools to do so is with permute. That's basically all about the way vectorized approach stated earlier would work.

Thus, your kernel code -

... case {'dist_histint','ih'} [m,d]=size(A); [n,d1]=size(B); if (d ~= d1) error('column length of A (%d) != column length of B (%d)\n',d,d1); end % With the MATLAB JIT compiler the trivial implementation turns out % to be the fastest, especially for large matrices. D = zeros(m,n); for i=1:m % m is number of samples of A if (0==mod(i,1000)) fprintf('.'); end for j=1:n % n is number of samples of B D(i,j) = sum(min([A(i,:);B(j,:)]));%./max(A(:,i),B(:,j))); end end

reduces to -

... case {'dist_histint','ih'} [m,d]=size(A); [n,d1]=size(B); if (d ~= d1) error('column length of A (%d) != column length of B (%d)\n',d,d1); end D = squeeze(sum(bsxfun(@min,A,permute(B,[3 2 1])),2)) %// OR D = sum(bsxfun(@min,permute(A,[1 3 2]),permute(B,[3 1 2])),3)

I am assuming the line: if (0==mod(i,1000)) fprintf('.'); end isn't important to the calculations as it does printing of some message.

160000 is not a timestamp in any way that PHP (or other common systems) define a timestamp. What you have is merely a time of day expressed in "military time" stored as an integer. So first of all, any gm function is likely not what you want to use, since you are missing timezone information from this "timestamp" to begin with, hence conversion to GM time is ambiguous if not impossible.

The best you may be able to do is:

$timestamp = DateTime::createFromFormat('His', sprintf('%06d', 160000))->format('U'); echo strftime('%H:%M', $timestamp);

16610057 0 Spring JPA 2.0 Repository / Factory not working

I'm trying to implement a custom java Spring JPA repository, as described in the Spring documentation. It seems that my spring config insists on creating the repositories in the standard way, instead of using the given MyRepositoryFactoryBean, giving me

Caused by: org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [com.myapp.repository.impl.DocumentRepositoryImpl]: No default constructor found; nested exception is java.lang.NoSuchMethodException: com.myapp.repository.impl.DocumentRepositoryImpl.<init>() at org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate(SimpleInstantiationStrategy.java:83) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.instantiateBean(AbstractAutowireCapableBeanFactory.java:1006) ... 43 more Caused by: java.lang.NoSuchMethodException: com.myapp.repository.impl.DocumentRepositoryImpl.<init>() at java.lang.Class.getConstructor0(Class.java:2730) at java.lang.Class.getDeclaredConstructor(Class.java:2004) at org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate(SimpleInstantiationStrategy.java:78)

I'm using Spring 3.2.2-RELEASE and spring-data-jpa-1.3.2-RELEASE, which is the latest if I'm correct. Here's my spring config:

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd"> <import resource="spring-repository-config.xml"/> <import resource="spring-security-config.xml"/> <context:component-scan base-package="com.myapp.web.controller"/> <context:component-scan base-package="com.myapp.webservice.controller"/>

And here's the spring-repository-config.xml:

<?xml version="1.0" encoding="UTF-8"?> <beans:beans xmlns="http://www.springframework.org/schema/data/jpa" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd"> <repositories base-package="com.myapp.repository" factory-class="com.myapp.repository.impl.MyRepositoryFactoryBean"/> <!-- entity-manager-factory-ref="entityManagerFactory" transaction-manager-ref="transactionManager" -->

If've added debug breakpoints in all the methods of the com.myapp.repository.impl.MyRepositoryFactoryBean class, but these were not called.

The basic interface, just like in the example

package com.myapp.repository.impl; @NoRepositoryBean public interface MyRepository<T, ID extends Serializable> extends JpaRepository<T, ID> {

The base implementation:

package com.myapp.repository.impl; @NoRepositoryBean public class MyRepositoryImpl<T, ID extends Serializable> extends SimpleJpaRepository<T, ID> implements MyRepository<T, ID> { private EntityManager entityManager; public MyRepositoryImpl(Class<T> domainClass, EntityManager entityManager) { super(domainClass, entityManager); // This is the recommended method for accessing inherited class dependencies. this.entityManager = entityManager; } public void sharedCustomMethod(ID id) { // implementation goes here } }

And the factory:

package com.myapp.repository.impl; import java.io.Serializable; import javax.persistence.EntityManager; import org.springframework.data.jpa.repository.JpaRepository; import org.springframework.data.jpa.repository.support.JpaRepositoryFactory; import org.springframework.data.jpa.repository.support.JpaRepositoryFactoryBean; import org.springframework.data.repository.core.RepositoryMetadata; import org.springframework.data.repository.core.support.RepositoryFactorySupport; public class MyRepositoryFactoryBean<R extends JpaRepository<T, I>, T, I extends Serializable> extends JpaRepositoryFactoryBean<R, T, I> { protected RepositoryFactorySupport createRepositoryFactory(EntityManager entityManager) { return new MyRepositoryFactory(entityManager); } private static class MyRepositoryFactory<T, I extends Serializable> extends JpaRepositoryFactory { private EntityManager entityManager; public MyRepositoryFactory(EntityManager entityManager) { super(entityManager); this.entityManager = entityManager; } protected Object getTargetRepository(RepositoryMetadata metadata) { return new MyRepositoryImpl<T, I>((Class<T>) metadata.getDomainType(), entityManager); } protected Class<?> getRepositoryBaseClass(RepositoryMetadata metadata) { // The RepositoryMetadata can be safely ignored, it is used by the JpaRepositoryFactory // to check for QueryDslJpaRepository's which is out of scope. return MyRepositoryImpl.class; } } }

My repositories interfaces are defines as:

package com.myapp.repository; public interface DocumentRepository { // extends MyRepository<Document, Long> public Document findByDocumentHash(String hashCode); public Document findById(long id); }

And the implementation is

package com.myapp.repository.impl; import java.io.Serializable; import javax.persistence.EntityManager; import javax.persistence.PersistenceContext; public class DocumentRepositoryImpl<Document, ID extends Serializable> extends MyRepositoryImpl<Document, Serializable> { private static final long serialVersionUID = 1L; public DocumentRepositoryImpl(Class<Document> domainClass, EntityManager entityManager) { super(domainClass, entityManager); }

And I use these repositories as autowired refernces in my controllers:

package com.myapp.web.controller; @Controller @RequestMapping(value = "/documents") public class DocumentController { @Autowired private DocumentRepository documentRepository; @RequestMapping(method = RequestMethod.GET) public ModelAndView list(HttpServletRequest request) { this.documentRepository. ... }

I've looked at various resources on the web like this one, but I can't tell the difference with my code. Any hints are more than welcome!

I assume that you meant to return the list local variable that you declare in the returnLists function. What you'll be getting back is actually the class variable, also called list. This is because the local list variable has gone out of context by the time the code reaches your return statement (the local list variable is within the context of the try block you have declared). If you want to return the value from the local list variable change the first couple of lines of returnLists to this:

public List returnLists(String fileN) { mp3Lister woww = null; String fName; String lName; mp3Lister qwewq; List list = new LinkedList(); try {

and then remove the declaration of the list variable inside the try block.

you should expose a DateTime dependency property on the control, done like so:

 public DateTime Day { get { return (DateTime)GetValue(DayProperty); } set { SetValue(DayProperty, value); } } // Using a DependencyProperty as the backing store for Day. This enables animation, styling, binding, etc... public static readonly DependencyProperty DayProperty = DependencyProperty.Register("Day", typeof(DateTime), typeof(DayOfWeek), new UIPropertyMetadata(DateTime.MinValue));

if you want this to be auto generated, what you should do is have an ItemsControl that contains this dayControl of yours, like so:

 <ItemsControl x:Name="DaysItemsControl"> <ItemsControl.ItemTemplate> <DataTemplate> <custom:DayDisplay Day="{Binding}"/> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl>

and then DataBind it from code behind:

 DateTime[] week = new DateTime[] { new DateTime(2000,1,1), new DateTime(200,1,2) }; DayItemsControl.ItemsSource = week;

In the calendar setter area you getting the instance with actual date, then changing it's value, but not with add or substracting some piece of time. It's value is totally differs from the expected, because you setting absolute values not relatives.

I've just extracted the calendar changes from your code and executed to demonstrate:

Calendar calendar = Calendar.getInstance(); System.out.println(calendar.getTime()); calendar.set(Calendar.DAY_OF_WEEK, 0); calendar.set(Calendar.HOUR_OF_DAY, 0); calendar.set(Calendar.MINUTE, 1); calendar.set(Calendar.SECOND, 0); System.out.println(calendar.getTime()); calendar.add(Calendar.HOUR, 1); System.out.println(calendar.getTime());

the result is:

You can do it with Generalized Algebraic Data Types. We can create a generic (GADT) type with data constructors that have type constraints. Then we can define specialized types (type aliases) that specifies the full type and thus limiting which constructors are allowed.

{-# LANGUAGE GADTs #-} data Zero data Succ a data Axis a where X :: Axis (Succ a) Y :: Axis (Succ (Succ a)) Z :: Axis (Succ (Succ (Succ a))) type Axis2D = Axis (Succ (Succ Zero)) type Axis3D = Axis (Succ (Succ (Succ Zero)))

Now, you are guaranteed to only have X and Y passed into a function that is defined to take an argument of Axis2D. The constructor Z fails to match the type of Axis2D.

Unfortunately, GADTs do not support automatic deriving, so you will need to provide your own instances, such as:

instance Show (Axis a) where show X = "X" show Y = "Y" show Z = "Z" instance Eq (Axis a) where X == X = True Y == Y = True Z == Z = True _ == _ = False

23598839 0 angular.js nested directive scope scope attribute

I would like to to a "map" tag witch should contains "marker" tags.

my problem is that I would like to set the "marker" attributes using variables from the "map" parent scope.

if I do this:

 <map center="{{userPosition}}"> <marker lat="13.555232324" lng="43.555232324" text="Text1" on-click="callback('id_0')" ></marker> </map>

my code works, but I would like to do something like:

 <map center="{{userPosition}}"> <marker lat="{{nearRooms['id_0'].lat}}" lng="{{nearRooms['id_0'].lng}}" text="Text1" on-click="callback('id_0')" ></marker> </map>

right now I can just read "lat" as a string.

my map directive:

ngBMap.directive('map', [ function ($compile){ return { restrict: 'E', controller: ['$scope', function($scope) { this.markers = []; $scope.markers = []; this.mapHtmlEl = null this.map = null; this.exeFunc = function(func, context, args){ $scope.$parent[func].apply(context, args) } this.initializeMarkers = function(){ for (var i=0; i<this.markers.length; i++) { var marker = this.markers[i]; this.map.entities.push(marker); } } this.initializeMap = function(scope, elem, attrs){ var map_canvas = document.createElement('div') var _thisCtrl = this; .... this.mapHtmlEl = map_canvas; } this.setCenter = function(position){ var position = eval(position) var _position = new Microsoft.Maps.Location(position[0], position[1]) if(this.map) this.map.setView({center : _position}); } }], scope: { 'center': '@', }, link: function(scope, element, attrs, ctrl) { scope.$watch('center', function(center) { console.log('center: '+center) if(center){ ctrl.setCenter(center) } }, false); ctrl.initializeMap(scope, element, attrs) element.html(ctrl.mapHtmlEl) } }

}]);

my marker directive:

ngBMap.directive('marker', [ function ($compile){ return { restrict: 'E', require: '^map', link: function(scope, element, attrs, mapController) { console.log('marker init') var getMarker = function() { var lat = attrs.lat ..... var marker = _marker; return marker; }//end getMarker var marker = getMarker(); mapController.markers.push(marker); } }}]);

Simply put you can't. There are a couple of approaches to work around this problem though.

The most common is to use an interface. Say IMyType

interface IMyType { void foo(); } class A : IMyType ... class B : IMyType ... void bar<T>(T t) where T : IMyType { t.Foo(); }

This is a bit heavy weight though is it requires a metadata change for a solution. A cheaper approach is to provide a lambda expression which calls the appropriate function.

void bar<T>(T t, Action doFoo) { ... doFoo(); } var v1 = new A(); var v2 = new B(); bar(v1, () => v1.Foo()); bar(v2, () => v2.Foo());

Basically, in mathematics, there is a concept of "Lebesgue Measure". This assigns values to length, area, volume, etc. by manipulating the interval [0,1].

Here's an intituitive explanation. A point at x can be represented as a limiting case of the interval [x,x+h] as h approaches 0. The measure of the point, (x+h) - x = h as h approaches 0 is therefore 0.

However, if we take a line segment--say, [0,1]--and decompose it into n intervals I[k] with k being over the integers from 0 to n-1, each will take the form I[k] = [k/n, k/n + 1/n)]. If we let n go to infinity, each of the I[k] can be modeled as a point because 1/n is approaching 0. If we take the measure of each point, we get 1/n as n approaches infinity, or zero. On the other hand, if we sum the measures of the points, we get 1/n * n = 1, the measure of [0,1].

I need your assistant in updating the <p:message> component in a JSF page once the non-ajax <p:commandButton> is clicked. Currently in the case, I need to validate if the employee number is null, then show the error message in the message component, else, nothing to be shown. But now,the form is not showing anything once the <p:commandButton> is clicked.

Below is the JSF code:

<h:form id="form"> <p:inputText value="#{pdf.refNo}"/> <p:message id="message" for=":form:cmd2" showDetail="true"/> <p:commandButton id="cmd2" value="Validate" ajax="false" actionListener="#{pdf.validate}"/> </h:form>

And the Java bean is:

public void validate() { if (refNo.equals("") || refNo == null) { FacesContext.getCurrentInstance().addMessage(":form:cmd2", new FacesMessage(FacesMessage.SEVERITY_ERROR, "Error!", "Please enter the Employee No.")); } }

So is the above code is correct and how to show the message once the button is clicked?

Use == on objects to perform identity comparison.

That is what the default implementation of equals() does, but one normally overrides equals() to serve as an "equivalent content" check.

As already mentioned, you can instruct RAND to generate numbers directly as single precision, and it's definitely best to generate the numbers in a decent sized chunk. If you still need more performance, and you have Parallel Computing Toolbox and a supported NVIDIA GPU, the gpuArray.rand function can be even faster, especially if you select the philox generator like so:

parallel.gpu.RandStream('Philox4x32-10')

I would not have them answer "Yes" then type in the new value. Just have them type in the new value if they want one, or leave it blank to accept the default.

This little function lets you set multiple variables in one call:

function confirm() { echo "Confirming values for several variables." for var; do read -p "$var = ${!var} ... leave blank to accept or enter a new value: " case $REPLY in "") # empty use default ;; *) # not empty, set the variable using printf -v printf -v "$var" "$REPLY" ;; esac done }

Used like so:

$ foo='foo_default_value' $ bar='default_for_bar' $ confirm foo bar Confirming values for several variables. foo = foo_default_value ... leave blank to accept or enter a new value: bar bar = default_for_bar ... leave blank to accept or enter a new value: foo=[bar], bar=[default_for_bar]

Of course, if blank can be a default, then you would need to account for that, like @jm666 use of read -i.

To hav transparency, you need an alpha channel, on your texture, but more important, in your framebuffer. This is done with SDL_GL_SetAttribute, for example:

SDL_GL_SetAttribute( SDL_GL_RED_SIZE, 8 ); SDL_GL_SetAttribute( SDL_GL_GREEN_SIZE, 8 ); SDL_GL_SetAttribute( SDL_GL_BLUE_SIZE, 8 ); SDL_GL_SetAttribute( SDL_GL_ALPHA_SIZE, 8 );

This will request a framebuffer with at least those sizes, and you'll be able to use blending. Remember to enable blending and set a blending function.

So, if now i need to make a ssl request i will have to use HttpsURLConnection (?) and create a request.

My question is -How does HttpsURLConnection know about the encryption algorithm and then encrypts using that?

Yes you have to use HttpsURLConnection. But you dont have to do it explicitly. new URL("https://google.pl").openConnection(); is more then enough.

In Server Hello, server anounces what encrypiton it can accept. All encryption methods have to "announce" themselves so the server knows how to interpret them. So when you initiatle the connection, servers says what it can handle, client choose one of the cipers and ciper the data using it. At the beginning of the connection, client announces what suite will it use.

This information can be public to this is not a problem that this is sent as plaintext. The point is, to exchange the symetric key between client in server in private way, so the rest of communication can be ciphered usint that key.

How is session maintained? How does HttpsURLConnection know that this connection has already been initiated and handshake procedures have already been completed?

Well SSL stands for Secure Socket Layer. It means that data transmit and received is ciphered, decrypted on raw socket(streams) level; You can open SSL connection to transmit data from point to point not only via Https

There is no "session". As long as you open a connection, you got 2 streams. Input and Output. As long as those are open, you can write data or read from them. Once they are closed, you will have to initiate another connection.

Every Http request is a new connection (unless Keep-Alive is sent). JsessionId for example, or php's sessionid is to identity that you are the same client that made requests earlier so it can "simulate" constant connection.

I got some tips from the internet, and following is the steps to get iOS acceptable p12 key and certification file:

convert XML to PEM
Shell> compile XMLSpec2PEM.java
Shell> XMLSpec2PEM rsa.xml
save the output result to rsa.pem
(borrow from here)
convert PEM to RSA Private Key
OpenSSL> rsa -in rsa.pem -out rsaPrivate.key
Generate a certification request
OpenSSL> req -new -key rsaPrivate.key -out rsaCertReq.crt
(input some basic certification data)
Sign certification of the request
OpenSSL> x509 -req -days 3650 -in rsaCertReq.crt -signkey rsaPrivate.key -out rsaCert.crt
Convert the certification file format to DER (iOS acceptable format)
OpenSSL> x509 -outform der -in rsaCert.crt -out rsaCert.der
Generate PKCS12 Private key(iOS acceptable format)
OpenSSL> pkcs12 -export -out rsaPrivate.pfx -inkey rsaPrivate.key -in rsaCert.crt

No further steps, files generated in step 5 and 6 now can be used in iOS!

As @Warren pointed out, anderson_ksamp is not available in scipy version .12.1. It is a relatively new addition to scipy.

I'm not a fedora user. That said, it sounds like installing scipy using pip is your best bet.

Step one: install dependencies. Check Muneeb's answer for information on how to install blas and lapack on fedora. It should be as simple as:

sudo yum install lapack lapack-devel blas blas-devel

Step two: install scipy using pip.

sudo pip install --upgrade scipy

This process will take a long time. Get lunch. You should have a working copy of scipy when you get back.

Note, if you don't have pip, run the following command:

sudo yum install python-pip

1201230 0 SharePoint > Custom Page-Library & PageLayout

I have a custom page-library which a custom content-type and a page-layout all inside a site-definition.

Works as expected. The only thing I cannot get around is that if I upgrade the solution with the page-lib, ctype, page-layout via stsadm everything is updated except the page-layout.

New fields in the ctype --> no problem Changed views in the page-lib --> no problem

Updated PageLayout --> ERROR

The page-layout section:

<!-- specific page-layout to display LKW data --> <File Url="CustomPage.aspx" Type="GhostableInLibrary" IgnoreIfAlreadyExists="TRUE" > <Property Name="Title" Value="$Resources:CustomLayouts,Title;" /> <Property Name="MasterPageDescription" Value="$Resources:cmscore,PageLayout_BlankWebPartPage_Description;" /> <Property Name="ContentType" Value="$Resources:cmscore,contenttype_pagelayout_name;" /> <Property Name="PublishingPreviewImage" Value="~SiteCollection/_catalogs/masterpage/$Resources:core,Culture;/Preview Images/BlankWebPartPage.png, ~SiteCollection/_catalogs/masterpage/$Resources:core,Culture;/Preview Images/BlankWebPartPage.png" /> <Property Name="PublishingAssociatedContentType" Value=";#$Resources:FieldsCTypes,cTypeDisplayName;;#0x010100C568DB52D9D0A14D9B2FDCC96666E9F2007948130EC3DB064584E219954237AF3900D38AAFB8072F441984BC947D49503947;#" /> </File>

The relevant section in the onet.xml:

<Module Name="Home" Url="$Resources:cmscore,List_Pages_UrlName;Custom" Path=""> <File Url="Default.aspx" Type="GhostableInLibrary" IgnoreIfAlreadyExists="TRUE"> <Property Name="Title" Value="$Resources:Layouts,DisplayName;" /> <Property Name="ContentType" Value="$Resources:cmscore,contenttype_welcomepage_name;"/> <Property Name="PublishingPageLayout" Value="~SiteCollection/_catalogs/masterpage/CustomPage.aspx, $Resources:PalfingerPlatformsOrderRoot,LKWpageDefaultTitle;" /> <Property Name="PublishingPageContent" Value="" /> </File> </Module>

The strange thing is, if I just have a page-layout with no underlying page-library I can update the page-ayout. The problem only occurs if I use a custom page-layout inside a custom page-library.

I did some Google search and found a hint - the problem could be that the page-layout is unghosted. I checked this with a small sample code:

SPFile file = folder.Files["Default.aspx"]; if (file.CustomizedPageStatus == SPCustomizedPageStatus.Customized) { file.RevertContentStream(); }

After executing the code the Page-Layout is upgraded and uses the new page-layout.

The Problem is that this is no real solution for me because I have approx. 1000 site-collections using the site-def. and the page-layout. Updating all of them is quite painful. Does anybody know a solution for this?

Assuming that listings is indexed on id:

If your id is an integer:

SELECT listings.id, listings.price, listings.seller_id, sellers.blacklisted FROM listings INNER JOIN sellers ON sellers.id = listings.sellers_id WHERE listings.price > 100 AND sellers.blacklisted = 0 AND listings.ID LIKE CONCAT(CEIL(RAND() * 100),'%') LIMIT 4

and if it's ascii

SELECT listings.id, listings.price, listings.seller_id, sellers.blacklisted FROM listings INNER JOIN sellers ON sellers.id = listings.sellers_id WHERE listings.price > 100 AND sellers.blacklisted = 0 AND listings.ID LIKE CONCAT(CHAR(CEIL(RAND() * 100)),'%') LIMIT 4

basically my advice to speed things up is dump the order by. On anything over a few records you're adding measurable overhead.

ps please forgive me if concat can't be used this way in mqsql; not entirely certain whether it'll work.

15527578 0 Generate dynamic select lambda expressions

I am somewhat new to expression trees and I just don't quite understand some things.

What I need to do is send in a list of values and select the columns for an entity from those values. So I would make a call something like this:

DATASTORE<Contact> dst = new DATASTORE<Contact>();//DATASTORE is implemented below. List<string> lColumns = new List<string>() { "ID", "NAME" };//List of columns dst.SelectColumns(lColumns);//Selection Command

I want that to be translated into code like this (Contact is an entity using the EF4):

Contact.Select(i => new Contact { ID = i.ID, NAME = i.NAME });

So let's say I have the following code:

public Class<t> DATASTORE where t : EntityObject { public Expression<Func<t, t>> SelectColumns(List<string> columns) { ParameterExpression i = Expression.Parameter(typeof(t), "i"); List<MemberBinding> bindings = new List<MemberBinding>(); foreach (PropertyInfo propinfo in typeof(t).GetProperties(BindingFlags.Public | BindingFlags.Instance)) { if (columns.Contains(propinfo.Name)) { MemberBinding binding = Expression.Bind(propinfo, Expression.Property(i, propinfo.Name)); bindings.Add(binding); } } Expression expMemberInit = Expression.MemberInit(Expression.New(typeof(t)), bindings); return Expression.Lambda<Func<t, t>>(expMemberInit, i); }

When I ran the above code I got the following error:

The entity or complex type 'Contact' cannot be constructed in a LINQ to Entities query.

I looked at the body of the query and it emitted the following code:

{i => new Contact() {ID = i.ID, NAME = i.NAME}}

I am pretty sure that I should be able to construct the a new entity because I wrote this line explicitly as a test to see if this could be done:

.Select(i => new Contact{ ID = i.ID, NAME = i.NAME })

This worked, but I need to construct the select dynamically.

I tried decompiling a straight query(first time I have looked at the low level code) and I can't quite translate it. The high level code that I entered is:

Expression<Func<Contact, Contact>> expression = z => new Contact { ID = z.ID, NAME = z.NAME };

Changing the framework used in the decompiler I get this code:

ParameterExpression expression2; Expression<Func<Contact, Contact>> expression = Expression.Lambda<Func<Contact, Contact>> (Expression.MemberInit(Expression.New((ConstructorInfo) methodof(Contact..ctor), new Expression[0]), new MemberBinding[] { Expression.Bind((MethodInfo) methodof(Contact.set_ID), Expression.Property(expression2 = Expression.Parameter(typeof(Contact), "z"), (MethodInfo) methodof(Contact.get_ID))), Expression.Bind((MethodInfo) methodof(Contact.set_NAME), Expression.Property(expression2, (MethodInfo) methodof(Contact.get_NAME))) }), new ParameterExpression[] { expression2 });

I have looked several places to try and understand this but I haven't quite gotten it yet. Can anyone help?

These are some places that I have looked:

msdn blog -- This is exactly what I want to do but my decopiled code soes not have Expression.Call.
msdn MemberInit
msdn Expression Property
stackoverflow EF only get specific columns -- This is close but this seems like it is doing the same thing as if i just use a select off of a query.
stackoverflow lambda expressions to be used in select query -- The answer here is exactly what I want to do, I just don't understand how to translate the decompiled code to C#.

I had this exact problem today, while making a sample project for another SO answer! It looks like your xib is trying to connect an outlet to your view controller instead of your cell. In your screenshot, the outlets look correctly defined, but occasionally an old outlet definition can get left in the underlying XML and cause this type of crash.

If you've changed the files owner class after connecting some outlets, for example, this could confuse it.

You may be able to find it by opening the xib as "source code", look for the element and check there are only the entries you expect. Perhaps search the XML file for albumLabel as well.

If that doesn't work, you may have to scrap the xib and start again.

The default behavior of ViewSwitcher, as inherited by ViewAnimator, is to consider all child views on layout, which will result in the ViewSwitcher occupying the space of the largest child.

To change this, all you need to do is to set the MeasureAllChildren flag to false. This will make the layout pass ignore the child view that is currently hidden. Set this flag e.g. in the onCreate method of the activity, e.g.:

 ViewSwitcher switcher = (ViewSwitcher)findViewById(R.id.ViewSwitcher); switcher.setMeasureAllChildren(false);

XML example:

<ViewSwitcher xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/viewSwitcher" android:measureAllChildren="false"> </ViewSwitcher>

To send a message via these services I need to supply the international number, however, I do not want to have to ask my users to provide the full international number - just their normal number that they would give to anyone in their own country (I don't expect them to know their international dialling codes, etc).

So what is the best way to convert a local national number into an international one? As well as their number, each user will be asked to provide their country. (My user base will be international.)

Should I add an extra field to the Country table that holds the international dialling code - and then just construct the full international number? This seems ok until you consider that some countries require omitting the 0 at the start of the number, and others don't.
Is there an easier way? Or gem out there that does this?

Online Check, This is just a demo example.

See below the real example:

At first you need to use array_search for get the position of the same data, if exist then just remove it using $arr[$pos] = '';, and each and every time you need to import data into the new array called $arr and after completing fetching data you need to use a foreach loop to print them.

$arr = array(); foreach($query->result() as $row){ $pos = array_search($row->name, $arr); if($pos !== false) $arr[$pos] = ''; $arr[] = $row->name; } foreach($arr as $val){ echo $val.'<br/>'; }

Check this and let me know.

3748538 0 Getting warning from C math library's pow function

I have the following function in my code:

I'm at a loss for what is causing this... any ideas?

The freezing is due to the fact you are trying to change your progress bar contained on the UI thread from your worker thread. I would recommend raising an event from within your worker Progress function to a handler on the UI thread. You will need to marshall the call to the handler on the thread as below.

private object _lock = new object(); //should have class scope private void ShowProgressControl(EventArgs e) { if (this.InvokeRequired) { lock (_lock) { EventHandler d = new EventHandler(ShowProgressControl); this.Invoke(d, new object[] { e }); return; } } else { //Show your progress bar. } }

Enjoy!

When catch exceptions I usually find that more specific is better, that being said typing out all of those different blocks that do the same thing can get really annoying. Thankfully in the Java 7 release a try-catch notation was added where you can specific multiple exceptions for a single block:

try{ //some statements } catch (KeyStoreException | CertificateException | NoSuchAlgorithmException | FileNotFoundException | IOException | UnrecoverableKeyException | NoPropertyFoundException e) { LOGGER.error(e); }

This sounds like what you are looking for, but there is more detailed information in the Oracle docs: http://docs.oracle.com/javase/7/docs/technotes/guides/language/catch-multiple.html

3376479 1 Django object extension / one to one relationship issues

Howdy. I'm working on migrating an internal system to Django and have run into a few wrinkles.

Intro
Our current system (a billing system) tracks double-entry bookkeeping while allowing users to enter data as invoices, expenses, etc.

Base Objects
So I have two base objects/models:

JournalEntry
JournalEntryItems

defined as follows:

 class JournalEntry(models.Model): gjID = models.AutoField(primary_key=True) date = models.DateTimeField('entry date'); memo = models.CharField(max_length=100); class JournalEntryItem(models.Model): journalEntryID = models.AutoField(primary_key=True) gjID = models.ForeignKey(JournalEntry, db_column='gjID') amount = models.DecimalField(max_digits=10,decimal_places=2)

So far, so good. It works quite smoothly on the admin side (inlines work, etc.)

On to the next section.
We then have two more models

InvoiceEntry
InvoiceEntryItem

An InvoiceEntry is a superset of / it inherits from JournalEntry, so I've been using a OneToOneField (which is what we're using in the background on our current site). That works quite smoothly too.

 class InvoiceEntry(JournalEntry): invoiceID = models.AutoField(primary_key=True, db_column='invoiceID', verbose_name='') journalEntry = models.OneToOneField(JournalEntry, parent_link=True, db_column='gjID') client = models.ForeignKey(Client, db_column='clientID') datePaid = models.DateTimeField(null=True, db_column='datePaid', blank=True, verbose_name='date paid')

Where I run into problems is when trying to add an InvoiceEntryItem (which inherits from JournalEntryItem) to an inline related to InvoiceEntry. I'm getting the error:

 <class 'billing.models.InvoiceEntryItem'> has more than 1 ForeignKey to <class 'billing.models.InvoiceEntry'>

The way I see it, InvoiceEntryItem has a ForeignKey directly to InvoiceEntry. And it also has an indirect ForeignKey to InvoiceEntry through the JournalEntry 1->M JournalEntryItems relationship.

Here's the code I'm using at the moment.

 class InvoiceEntryItem(JournalEntryItem): invoiceEntryID = models.AutoField(primary_key=True, db_column='invoiceEntryID', verbose_name='') invoiceEntry = models.ForeignKey(InvoiceEntry, related_name='invoiceEntries', db_column='invoiceID') journalEntryItem = models.OneToOneField(JournalEntryItem, db_column='journalEntryID')

I've tried removing the journalEntryItem OneToOneField. Doing that then removes my ability to retrieve the dollar amount for this particular InvoiceEntryItem (which is only stored in journalEntryItem).
I've also tried removing the invoiceEntry ForeignKey relationship. Doing that removes the relationship that allows me to see the InvoiceEntry 1->M InvoiceEntryItems in the admin inline. All I see are blank fields (instead of the actual data that is currently stored in the DB).

It seems like option 2 is closer to what I want to do. But my inexperience with Django seems to be limiting me. I might be able to filter the larger pool of journal entries to see just invoice entries. But it would be really handy to think of these solely as invoices (instead of a subset of journal entries).

Any thoughts on how to do what I'm after?

16874373 0 How do I declare a string as a user input, then check to see if it's "yes" or "no"? (JAVA)

I cannot get my program to take a user input as a string and then see if it equals "yes" or "no" and if it equals neither, then to display "incorrect entry." It always displays "incorrect entry" regardless if I type "yes" or "no." I have tried a few different types of if and do/while's but I just can't seem to get it:

Class file:

import java.util.Scanner; public class PhysicsProblem { private double vI; // initial velocity private double vF; // final velocity private double t; // time private double deltaX; // change in the x value //Make sure to add acceleration public PhysicsProblem (double vI, double vF, double t, double deltaX) { this.vI = vI; this.vF = vF; this.t = t; this.deltaX = deltaX; } public void setVi(String strVi) { while (!(strVi.equals("no") || strVi.equals("yes"))); { System.out.println("incorrect entry"); } if (strVi.equals("yes")) { System.out.println("Enter the initial velocity: "); vI = new Scanner(System.in).nextDouble(); } if (strVi.equals("no")) { System.out.println("The program is assuming you want to solve" + "for intial velocity"); } }

Program:

import java.util.Scanner;

public class PhysicsProblemSolver { public static void main (String[] args) { double vI = 0; double vF = 0; double t = 0; double deltaX = 0; Scanner scan = new Scanner(System.in); PhysicsProblem problem1 = new PhysicsProblem (vI, vF, t, deltaX); // Checks to see if initial velocity is given System.out.println("Do you know the initial velocity? (Type 'yes' or 'no')"); String strVi = scan.next(); problem1.setVi(strVi);

I know it looks like an incomplete program, and it is, but I just needed help with this one section, so I tried not to include the unnecessary parts. Sorry if it's confusing!

11059458 0 Cannot nullify the padding on a elements in jQuery

I want to fill in all the options for things like

<select id=such_a_field>

to get the inputs in my form I can just go

$inputs = $('#myFormName :input');

and iterate through them and set the value based on the id. For my select field, which I am now upgrading from a simple input to restrict what the user can put in, I first want to go read the set of available options (from the DB, via ajax of course), and then set the right one based on what's in the DB. Unfortunately

$selects = $('#myFormName :select');

produces

Syntax error, unrecognized expression: unsupported pseudo: select

as of course :select isnt a pseudo selector. It would be enough just to extend my above :input selector and then enhance my field setting code to handle selects.

I am trying to access to the user id that is currently logged on... I have two controllers, LicencaController and ProcessoController. In the ProcessoController there is a function that saves the user id and some other stuff, this function was private, but in order to gain access I have change it to public..

Now in a function in the controller Licenca I instaciate an object ProcessoController and called the function on the ProcessoController...

The problem is that user.identity.name is null.

If from the ProcessoController I call the function to save the user id , user.identity.name gives me the username...

If from the LicencaController I call the function to save the user id that is declared in the ProcessoController, it gives me null... I have tried other solutions like the one in this topic:

I have the answer. Apparently jQuery doesn't support the default behavior of links clicked programmatically

Creating and submitting a form works really well though (tested in Chrome 26, FF 20 and IE 8):

var form = $("<form></form>"); form.attr( { id : "newform", action : "https://google.nl", method : "GET", target : "_blank" // Open in new window/tab }); $("body").append(form); $("#newform").submit(); $("#newform").remove();

What it does:

Create a form
Give it attributes
Append it to the DOM so it can be submitted
Submit it
Remove the form from the DOM

Now you have a new tab/window loading "https://google.nl" (or any URL you want, just replace it). Unfortunately when you try to open more than one window at once this way, you get an Popup blocked messagebar when trying to open the second one (the first one is still opened).

31252223 0

First, open() is used for files. What you want is opendir(). Next, when you use opendir(), readdir(), it doesn't keep the path information, so you need to prepend it to the files you're renaming. Third, it's more common to use lexical handles as opposed to bare names. Lastly, always use strict; and use warnings; which would have pointed you directly to the problem.

Here's a slightly updated version of your code:

#!/usr/bin/perl use warnings; use strict; my $dir = "/path/to/dir"; opendir(my $dh, $dir) or die $!; while ( my $file = readdir($dh) ) { next if ( $file =~ m/(^\.)/ ); next unless -f $file; if ( $file !~ m/csv$/ ) { print "*** renaming file $file ***\n"; my $oldfile = $file; $file =~ s/\..*$/.csv/; print "$oldfile => $file\n"; rename "$dir/$oldfile", "$dir/$file"; print "Done\n"; } }

Another way to do this is use a file glob (per suggestion by Sobrique):

#!/usr/bin/perl use warnings; use strict; my @files = </path/to/dir/*>; for my $file (@files){ next unless -f $file; if ($file !~ /\.csv$/){ print "*** renaming file $file ***\n"; my $oldfile = $file; $file =~ s/\..*$/.csv/; print "$oldfile => $file\n"; rename $oldfile, $file; print "Done!\n"; } }

32260332 1 Defining a constructor for ponyorm's Entities results in TypeError

i just wanted to try out the pony orm mapper for a small personal web application. Everything works fine except for defining a custom constructor for an entity.

In the following code i created a simple entity with a string field name and defined a constructor which does nothing but redirect the arguments to the parent constructor (in my real app i change some of the arguments bevor passing them to the parent constructor). After that i create one User and print its name.

from pony.orm import Database, Required, db_session, commit db = Database("sqlite", ":memory:", create_db=True) class User(db.Entity): def __init__(self, *args, **kwargs): super(User, self).__init__(*args, **kwargs) name = Required(str) db.generate_mapping(create_tables=True) with db_session: u = User(name="Admin") commit() print(u, u.name)

The error message is TypeError: object.__init__() takes no parameters in the same line as the super()call. It looks like the keyword arguments are sent to object instead of db.Entity. When i remove the constructor everything works

So why doesn't it work. Shouldn't a constructor like the one in my example just always work (and do nothing of course)? Is there something in ponyorm that prevents it from working or am i missing something here?

For completeness sake my entity definition actually looks like this

class User(db.Entity): def __init__(self, *args, **kwargs): if "password" not in kwargs: raise ValueError("password is required") kwargs["password"] = werkzeug.security.generate_password_hash(kwargs["password"]) super().__init__(*args, **kwargs) name = Required(str) password = Required(str)

It produces the same results.

Also in the official documentation it says that method creation in entities is allowed at least. http://doc.ponyorm.com/entities.html#adding-custom-methods-to-entities . But it doesn't say anything about constructors.

To combine all three of the above answers, you need the stopwords_en.txt as it begins testing for English language text

From http://wiki.apache.org/solr/LanguageAnalysis#Stopwords

Stopwords affect Solr in three ways: relevance, performance, and resource utilization.

From a relevance perspective, these extremely high-frequency terms tend to throw off the scoring algorithm, and you won't get very good results if you leave them. At the same time, if you remove them, you can return bad results when the stopword is actually important.

From a performance perspective, if you keep stopwords, some queries (especially phrase queries) can be very slow.

From a resource utilization perspective, if you keep stopwords, the index is much larger than if you remove them.

One tradeoff you can make if you have the disk space: You can use CommonGramsFilter/CommonGramsQueryFilter instead of StopFilter. This solves the relevance and performance problems, at the expense of even more resource utilization, because it will form bigrams of stopwords to their adjacent words.

What you need to do is copy the original version located in the /conf/lang folder of your solr directory into just the /conf directory

cp PATH/TO/solr/conf/lang/stopwords_en.txt PATH/TO/solr/conf

It is probably the McAfee on-access scanner that holds the lock. If you only use read access, it is bypassed. I believe that you can use the Sysinternals Process Viewer tool (free from Microsoft) to confirm that.

Not sure what subscription you have for McAfee, but you can define exception rules so that it does not scan this file.

3451451 0 Why do people spend so much time searching for, and hacking around with, "free" toolsets when superior pay ones are available?

Clarification: I'm referring to companies that pay developers, professionally. I understand why a "hobby" or "for fun" developer wouldn't want to (or couldn't afford) a fully-features pay tool, and may prefer to tinker. I'm talking about situations where a deadline is bearing down on a developer/company and development time is diverted away from the goal in pursuit of a "Free" tool to accomplish what a pay one is available to do.

I've noticed a number of Stack Overflow questions recently (they're not new, I've just recently taken notice) where people are searching for free alternatives to popular development tools for things like ALM, database comparison, and other functions for which there's a trivially costly pay alternative. The "Free" tag on Stack Overflow has 350 questions, and it doesn't take long to see dozens of examples of "Is there a FREE tool to do X?" followed by discussions that must have taken the asker hours to research and participate in.

It's not just about paying less - I'm often amazed at the hoops that some developers (or, perhaps more accurately, their companies) will go through to avoid paying for something - in some cases, a pay solution will be avoided in favor of a poorly documented, buggy, feature-incomplete open-source solution that results in dozens of hours of work that could have been avoided.

I understand the most obvious reasons:

Company is short on cash
Don't pay for something when a (functionally-comparable) free alternative is available
"Hobby" developers don't have the cash to spare, and since they're just learning, it doesn't make sense to pay for a toolset they're only tinkering with

However, I think the "short on cash" reasoning is completely bogus - as a developer not long out of college, I made about $50K annually, or $200/day (meaning my company probably paid close to $300/day to have me in my chair, all considered). When you compare that price to a $300 tool, the obvious answer is "if it's going to waste more than a day of your time, you should buy it instead and get back to work". However, that's not what I observe - people seem willing to kill dozens of hours to avoid paying for something that only costs $50.

Help me understand - as a developer myself of tools I'd like to one day sell, I want to understand the mentality. Have I been spoiled by working at a company that's not afraid to spend? Is there an ingrained reason developers (or their companies) don't want to spend money? Can people not accurately estimate the costs of "Free" tools in terms of lost productivity?

I'm not referring to instances where a great free alternative is available. For example, any of these tools is a great example of something you shouldn't pay for. However, let's say one of those lacks a key feature you need, and which a pay version of the same library provides - people seem to lean towards hacking around with the free version to add the needed functionality (or scaffold in the needed functionality) instead of ditching the free tool in favor of the pay (and feature-complete) version. I'm not saying that's the wrong choice, but it's just a choice I want to understand the reasoning to. The important point is that I'd like to - my intent is not to be argumentative.

which I suppose should be either:

html "<a href=\""+ link + "\">Activate your account on Kunega</a>"

otherwise you call a method html with params "<a href=", $, { link } (closure that returns "link") and ">Activate your account on Kunega</a>".

I am by no means an expert — when HQL stymies me, I rarely have qualms about bypassing the problem by switching to straight SQL — so I can't tell you if there is a better, more HQL-ish way to do this. But in your specific instance, where B.marker is always either 0 or 1, I suppose you could change

COUNT(CASE WHEN B.marker = 1 THEN 1 ELSE NULL END)

SUM(B.marker)

and

COUNT(CASE WHEN B.marker = 0 THEN 1 ELSE NULL END)

COUNT(*) - SUM(B.marker)

(though you may also need to wrap your SUMs in COALESCE(..., 0) — I'm not sure).

Is there a simple way for this? My solution(s) either add way too much overhead (i.e nested loops), or too much complexity (i.e. unique NSCountedSet) for something that I expect to be trivial.

Not sure...I learned the 2 technologies by writing a facebook API based on WCF and writing a WPF frontend to browse the albums of my friends. My reasoning was that if WCF can do form-encoded POSTs with bare XML responses then it should be up for a lot of things.

I've done similar thing once. Unfortunately Report Studio can't create prompts (and variables) dynamically. You can construct your set of prompts using JavaScript. Not Cognos prompts. HTML EditBoxes. Then carefully pass values from EditBoxes to real hidden prompt as text.

You should do basic connectivity tests, to determine what exactly that network is blocking.

Start with a simple ping and move on to UDP and TCP levels. You might find that some form of communication is allowed.

If not, you can try to tell their security guys to accept some form of communication between specific range of ip addresses and/or port numbers and adapt your application accordingly.

36883973 0 html5 multiple file upload with spring mvc 4 and spring boot

I'm trying to upload multiple files using spring mvc 4, spring boot and thymeleaf as template engine, but i'm not able to access the uploaded files, the files are dealt with as one multipart file with content type application/octet-stream. here's my front-end code:

 <form name="offer-form" th:action="@{/submit-property}" method="POST" enctype="multipart/form-data"> <!-- .. other inputs .. --> <div class="col-xs-12 margin-top-60"> <input id="file-upload"name="files[]" type="file" multiple="multiple"/> </div> <div class="col-xs-12"> <div class="center-button-cont margin-top-60"> <button type="submit" class="button-primary button-shadow"> <span>submit property</span> <div class="button-triangle"></div> <div class="button-triangle2"></div> <div class="button-icon"><i class="fa fa-lg fa-home"></i></div> </button> </div> </div> </form>

And the controller code:

import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import org.apache.tomcat.util.http.fileupload.IOUtils; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.core.io.FileSystemResource; import org.springframework.core.io.Resource; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.ModelAttribute; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.multipart.MultipartFile; import com.aq.domain.Property; import com.aq.service.AddPropertyFormDataInitializerService; @Controller public class PorpertySubmissionController { public static final Resource PICTURES_DIR = new FileSystemResource("./uploadedPictures"); //some unrelated code @RequestMapping(value="/submit-property", method=RequestMethod.GET) public String getSubmitPropertyForm(Model model) { model.addAttribute("property", new Property()); return "submit-property"; } @RequestMapping(value="/submit-property", method=RequestMethod.POST) public String submitProperty ( @ModelAttribute(value="property") Property property, @RequestParam("files[]") MultipartFile[] uploadedImages ) { //some unrelated code if(uploadedImages != null && uploadedImages.length > 0) { System.out.println("uploadedImages length: " + uploadedImages.length); for(MultipartFile imageFile : uploadedImages) { try { copyFileToPictures(imageFile); System.out.println("copied File: " + imageFile.getOriginalFilename() + " successfully."); } catch (IOException e) { System.err.println(e.getMessage()); e.printStackTrace(); } } } else { System.out.println("no images were uploaded"); } return "redirect:/submit-property"; } private Resource copyFileToPictures(MultipartFile file) throws IOException { System.out.println("File Original Name: " + file.getOriginalFilename()); System.out.println("File Name: " + file.getName()); System.out.println("File size: " + file.getSize()); System.out.println("File Content type: " + file.getContentType()); String fileExtension = getFileExtension(file.getOriginalFilename()); File tempFile = File.createTempFile("pic", fileExtension, PICTURES_DIR.getFile()); try (InputStream in = file.getInputStream(); OutputStream out = new FileOutputStream(tempFile)) { IOUtils.copy(in, out); } return new FileSystemResource(tempFile); } private static String getFileExtension(String name) { return name.substring(name.lastIndexOf(".")); } }

the output of the sysout:

uploadedImages length: 1 (even though i upload multiple files)

File Original Name (using getOriginalFileName):

File Name (using getName): files[]

File size: 0

File Content type: application/octet-stream

and then an exception when subsctring is called on the empty original file name.

I tried to add commons file upload to my POM and configured CommonsMultipartResolver bean, but then it always prints that there are no uploaded images (which means it's null or length=0)

Unlike what everyone else tells you, this is unrelated to Windows and File.separator.

String DIR_PATH = "a/b/c/" is just a String, neither Java nor the compiler make any attempt to understand what it could mean, so you get the same value both on Windows and Linux.

Also note that / works as a file separator both on Unix and Windows, so this isn't an issue either. When necessary, Java will convert / to \.

File DIR_FILE = new File(DIR_PATH); is a constant but new File() is still executed by the VM at runtime when the class is loaded. So the path is not converted to Windows format while the compiler generates byte code.

So the problem you describe must be elsewhere or an important part of the code example you posted was changed when you simplified it for the question. My guess is that someone put a Windows-style path into the code elsewhere or maybe the config and you overlooked this.

That said, a safe way to build paths is to use File(File, String):

File DIR_PATH = new File( "a", new File( "b", "c" ) );

This will always build a path that works, no matter what the file separator is. If you must, you can use

File DIR_PATH = "a" + File.separator + "b" + File.separator + "c";

but that can fail for more complex examples and it's more text to read.

If I understood well, you would like include the code from includefile.php into your test.php ?

You can't use include like that, but you should do it like that.

file_put_contents($file, file_get_contents('includefile.php'), FILE_APPEND);

This will append the content from includefile.php into your test.php

10311565 0

As I understand the problem this will work:

SELECT t.value, t.from_id, t.to_id, t.loop_id FROM MyResults t INNER JOIN ( SELECT From_ID, To_ID, MIN(Value) [Value] FROM MyResults WHERE Loop_ID % 2 = 0 GROUP BY From_ID, To_ID ) MinT ON MinT.From_ID = t.From_ID AND MinT.To_ID = t.To_ID AND MinT.Value = t.Value

However, if you had duplicate values for a From_ID and To_ID combination e.g.

value from_id to_id loop_id ------------------------------------- 0.1 A B 2 0.1 A B 4

This would return both rows.

If you are using SQL-Server 2005 or later and you want the duplicate rows as stated above you could use:

SELECT Value, From_ID, To_ID, Loop_ID FROM ( SELECT *, MIN(Value) OVER(PARTITION BY From_ID, To_ID) [MinValue] FROM MyResults ) t WHERE Value = MinValue

If you did not want the duplicate rows you could use this:

SELECT Value, From_ID, To_ID, Loop_ID FROM ( SELECT *, ROW_NUMBER() OVER(PARTITION BY From_ID, To_ID ORDER BY Value, Loop_ID) [RowNumber] FROM MyResults ) t WHERE RowNumber = 1

I see that pretty much all the different options have already been laid out in different answers, but instead of commenting on all to give you my impression on what I think you should do, I'll just create an answer myself.

Just to be clear on how I understand how the system works: All users can have multiple belongings, but any belonging can only be help by one person.

In this case, it makes the most sense to have a user_id in the belongings table that can tie a belonging to a person. Once a user_id is set, nobody else can claim it anymore.

Now, as to the 'favorite' part, there are several things you can do. What truly is the best way to do it strongly depends on the queries you plan on running on it. Some consider adding a JOIN table, but honestly this is a lot of additional data that is rather pointless; there is likely going to be the exact amount of rows in it as the user table and by putting it in a separate table, there is a lot you can't do (for example, see how many people DON'T have a favorite). Likewise, a JOIN table would make no sense for the user_belonging relationship, as there is a 1:1 relationship between the belonging and the amount of people who can have it.
So I believe there are two viable options: either add a field (/switch) in the belongings table to indicate of a user's belonging is his/ her favorite, or add a field to the user table to indicate which belonging is the user's favorite. I would personally think that the latter holds the most merit, but depending on the queries you run, it might make more sense to to the former. Overall, the biggest difference is whether you want to process things pre-insert or post-select; e.g. in the latter situation, you will have to run an independent query to figure out if the user already has a favorite (in the former case this won't be necessary as you would put a unique index on the field in the user table), whereas in a post-select situation you will have to do cross reference which of the selected belongings from the belonging table is the user's favorite.

Please let me know if I explained myself clearly, or if you have any further questions.

Thanks to the help of @RenatoMendesFigueiredo, @hasumedic & (the most part) @Cerad, without need of premium plan, I can see the point of this warning and figure it out.

In fact, a long time ago, I would make my service extending the ContainerAware rather than write the method directly, but forced to live with its limits (the service could not have extended another class).

In 2.4, the ContainerAwareTrait was added.

My guess is that the warning has been added in the same time as this trait, because :

1) No reason to write a setter or a constructor to inject the container if a trait that do it already exists.

2) No need of pass the container as an argument in an another goal than inject it to a service.

Also, I removed the setContainer method from the class of my service, make it use the ContainerAwareTrait and keep the the service definition as before.

And ...

Kudos!

I'm surprised you had to ask, since it's basic Javascript, really...

Since press is invoked from oToggleButton, the this keyword now holds a reference to oToggleButton, and not the controller (hence why the getView() method fails). Search for 'this keyword in inner function' for more info.

To solve this, simply add a reference to this outside the inner function:

var that = this;

and in your inner function, use the reference instead:

that.getView().addStyleClass("sapUiSizeCompact");

Your WHERE clause contains only joins. There are no filters. This means your query needs to consider all the rows in at least one table. From this it follows that your query should execute a FULL TABLE SCAN of at least one of your tables, not an indexed read. A full table scan is the most efficient way of getting all the rows in a table.

So don't fix the syntax of your INDEX hint, get rid of it.

Next, figure out which table should drive your query. This is business logic. Probably your requirement is something like

"Summarise BL_DETAILS and BL_FREIGHT for every row in BL_CONTAINERS."

In which case you might think you need a full table scan of BL_CONTAINERS. But if BL_FREIGHT has more rows than BL_CONTAINERS and every BLF_REF_NO matches a BL_REF_NO (i.e. there is a foreign key on BL_FREIGHT.BLF_REF_NO referencing BL_CONTAINERS.BL_REF_NO) it would probably be better to drive from BL_FREIGHT.

Note that this is true if you are only interested in BL_CONTAINERS which have matching BL_FREIGHT rows. But if you want to include containers which have not been used (i.e. they have no matching no BL_FREIGHT records) you need to use outer joins and drive off the BL_CONTAINERS table.

These considerations get more complicated when you throw BL_DETAILS into the mix. Your report seems to be based around the BL_DETAILS categories (as Jeffrey observes it is hard for us to understand your query without aliases or describes). So perhaps BL_DETAILS is the right candidate for driving table.

As you can see, tuning requires insight into the business logic and the details of the data model. You have that local knowledge, we do not.

There are tools which can help you. Oracle has EXPLAIN PLAN which will show you how the database will execute the query. The query optimizer gets better with each release so it matters which version of the database you're using. Here is the documentation for 10g.

The important thing to note is that you need to give the database accurate statistics, in order for it to come up with a good plan. Find out more.

I would say you try a total clean reinstall/rebuild with cordova. First off all you have to install cordova for that. If you want to know, how to get started with that you should have a look into the cordova documentation: Cordova CLI-Docs

After you installed cordova, you enter the Terminal and type in the following commands:

cd ~/desktop
cordova create test com.example.test test
cd test
cordova platform add android
cordova plugin add org.apache.cordova.device-motion
cordova build

Open the builded project in Eclipse and add

<!DOCTYPE html> <html> <head> <title>Acceleration Example</title> <script type="text/javascript" charset="utf-8" src="cordova.js"></script> <script type="text/javascript" charset="utf-8"> // Wait for device API libraries to load // document.addEventListener("deviceready", onDeviceReady, false); // device APIs are available // function onDeviceReady() { navigator.accelerometer.getCurrentAcceleration(onSuccess, onError); } // onSuccess: Get a snapshot of the current acceleration // function onSuccess(acceleration) { alert('Acceleration X: ' + acceleration.x + '\n' + 'Acceleration Y: ' + acceleration.y + '\n' + 'Acceleration Z: ' + acceleration.z + '\n' + 'Timestamp: ' + acceleration.timestamp + '\n'); } // onError: Failed to get the acceleration // function onError() { alert('onError!'); } </script> </head> <body> <h1>Example</h1> <p>getCurrentAcceleration</p> </body> </html>

Save all and deploy the project to your device. And let me know, if this worked or not.

git prevents you from altering your working directory in a way that overwrites local changes (e.g. in case of a checkout).

Since your checkout went smooth, it simply means that the local changes were not overwritten by it, so there's no need to worry. You're still in a consistent state.

Were you switching to a new branch perhaps? Or maybe the local changes were newly added files? That would explain why the checkout generated no conflicts.

If you always want to do a lookup on the string after the first space, then maybe you don't want to use an ArrayList

Maybe you should use a Map<String, String> of product, full name e.g. "S4", "Samsung S4" Then lookups will be much faster.

38395747 0 Bootstrap same height cards within cols

With Bootstrap 3.3.6 I want to make 3 cards.

<div class="row"> <div class="col-md-4"> <div class="card"> <p>Some dummy text here</p> <button>Click Here</button> </div> </div> <div class="col-md-4"> <div class="card"> <p>Some dummy text here</p> <button>Click Here</button> </div> </div> <div class="col-md-4"> <div class="card"> <p>Some dummy text here</p> <button>Click Here</button> </div> </div> </div> .card { border: 1px solid #ddd; border-radius: 5px; padding: 20px; }

Now that the Dummy text is not the same length, the cards will not be the same height.

I found a trick using flexbox here: How can I make Bootstrap columns all the same height?, but this will be working on the immediate children of the .row not the .card

Another thing, even if the cards will be the same height, the buttons will not be on the same line as they will follow the the text.

Rather than retrieving the id of the first .link element within the mouseover event listener, you need to get the id of the element you are mousing over.

Within the event listener, this refers to the element that is currently being moused over, therefore you would access the id using $(this).attr("id") or this.id:

Example Here

$(".link").on('mouseover', function () { $("#header").html("<h1>I mousedover on " + this.id + "</h1>"); });

It's worth pointing out that $(".link") returns a collection (a jQuery object) of elements. When accessing the id using $(".link").attr("id"), you are accessing the id of the first element within the jQuery object. That's why you text would always say 'london'.

You can't disable cookies only on your web browser control. The control is essentially an embedded Internet Explorer and shares the user's Internet Explorer settings. If you don't mind blocking cookies on all other instances of Internet Explorer (maybe you use Chrome or Firefox for the rest of your browsing) you can do the following:

(From: http://social.msdn.microsoft.com/Forums/en-US/winforms/thread/90834f20-c89f-42f9-92a8-f67ccee3799a/)

To block Cookies in WebBrowser control you can take the following steps, in fact, it's the same as to block Cookies in IE.

Choose "Internet Options" under the "Tools" menu on the IE;

Select the "Privacy" tab.

Click the "Advanced..." button in the "Settings" groupbox.

Check the "Override automatic cookie handling" option.

Check both "Block" options.

Click "OK"

You could also delete all the cookies after you visit a page, but I don't think this will fulfill your goal of being completely anonymous.

I did a little digging and I think you can use InternetSetOption and the INTERNET_SUPPRESS_COOKIE_PERSIST flag. According to the documentation, this will only work for Internet Explorer 8 and later.

private const int INTERNET_OPTION_SUPPRESS_BEHAVIOR = 3; //INTERNET_SUPPRESS_COOKIE_PERSIST - Suppresses the persistence of cookies, even if the server has specified them as persistent. [DllImport("wininet.dll", SetLastError = true)] private static extern bool InternetSetOption(IntPtr hInternet, int dwOption, IntPtr lpBuffer, int lpdwBufferLength);

Then when you initialize your app try:

InternetSetOption(IntPtr.Zero, INTERNET_OPTION_SUPPRESS_BEHAVIOR, IntPtr.Zero, 0);

Hopefully this puts you on the right track. See also:

First of all you will need to install some dependencies: matplotlib and numpy.

The first option is to use matplotlib animation like in this example:

import numpy as np import matplotlib.pyplot as plt import matplotlib.animation as animation def update_line(num, data, line): line.set_data(data[..., :num]) return line, fig1 = plt.figure() data = np.random.rand(2, 25) l, = plt.plot([], [], 'r-') plt.xlim(0, 1) plt.ylim(0, 1) plt.xlabel('x') plt.title('test') line_ani = animation.FuncAnimation(fig1, update_line, 25, fargs=(data,l),interval=50, blit=True) plt.show()

A more mathematical option is this one:

import matplotlib.pyplot as plt import numpy as np import time x = np.linspace(0, 1, 20) y = np.random.rand(1, 20)[0] plt.ion() fig = plt.figure() ay = fig.add_subplot(111) line1, = ay.plot(x, y, 'b-') for i in range(0,100): y = np.random.rand(1, 20)[0] line1.set_ydata(y) fig.canvas.draw() time.sleep(0.1)

I hope this is what you were searching for.

5268875 0 Is it a waste of time to use "Build Automatically" option for Java projects in Eclipse?

I'm developing J2EE webapps in Eclipse (RAD, actually). I've always used the "Project > Build automatically" option. However, I noticed that this isn't always necessary because Eclipse seems to push out changes to my server when I save a file. This works great but I'm wondering why this would be checked by default.

I can think of a few times when it makes sense to fully build and deploy the app:

After changing a XML configuation file that gets loaded at app startup (application.xml, web.xml, bean configuration xml files, etc)
After changing a static variable on a class

Other than this, I can't think of other times when it would be crucial (or useful) to enable the build automatically option. Am I incorrect in my above assumptions? Am I just wasting a bunch of time by building automatically??

Try using MVCGrabBag. It has a common code base for all the inputs. It uses enums and a bit of a different style in terms of getting it to work. But once you get your head wrapped around the basics you will not be disappointed. All you do is do a @Html.FullFieldEditor and it takes care of the rest with code. There is basically a Selector.cs and some other files that figure out, much like the @Html.EditorFor helper does, what input to create. And instead of using a bunch of /EditorTemplates/ it just has one that takes care of everything.

It appears to be fairly new, so I trust it will gain momentum. I have to imagine for those of us non-superhuman coders out there that this would alleviate the problem of not having any uniform structure to something that has been around since the dawn of the web (I'm talking inputs).

Good luck.

Your are asking the wrong question, so any answer we will give is also going to be wrong.

You are asking how to more effectively use the tool you have (SQL Server) to solve an unspecified problem.

The "job to be done" may be more easily solved with some other tool or a completely different design.

If you really-really need to use a Cartesian product of this volume, you should look at using Lazy Evaluation or the call-by-need design pattern. How you do this depends on the client language involved.

You MAY be able to create a T-SQL lazy-evaluation with a procedure and a few sequences, but that is just a hunch.

I would recommend against following the push paradigm that is suggested above and switch to the pull paradigm. The purpose of AWSIdentityProviderManager is to prompt you for a token only when the SDK needs it, not for you to set it externally periodically whether the SDK needs it or not. This way you don't have to manage token expiry yourself, just make sure your token is valid when logins is called and if it isn't you can use an AWSCompletionSource to get a fresh one.

Assuming you have integrated Facebook login, your IdentityProviderManager should look something like this:

import Foundation import AWSCore import FacebookLogin import FacebookCore class FacebookProvider: NSObject, AWSIdentityProviderManager { func logins() -> AWSTask<NSDictionary> { if let token = AccessToken.current?.authenticationToken { return AWSTask(result: [AWSIdentityProviderFacebook:token]) } return AWSTask(error:NSError(domain: "Facebook Login", code: -1 , userInfo: ["Facebook" : "No current Facebook access token"])) } }

To use it:

let credentialsProvider = AWSCognitoCredentialsProvider(regionType: AWSRegionType.YOUR_REGION, identityPoolId: "YOUR_IDENTITY_POOL_ID", identityProviderManager: FacebookProvider()) let configuration = AWSServiceConfiguration(region: AWSRegionType.usEast1, credentialsProvider: credentialsProvider) AWSServiceManager.default().defaultServiceConfiguration = configuration

And then to test getting credentials:

AWSServiceManager.default().defaultServiceConfiguration.credentialsProvider.credentials().continue(with: AWSExecutor.default(), with: { (task) -> Any? in print(task.result ?? "nil") return task })

BTW, I needed to add this to my app delegate to get Facebook Login to work with Swift which is not mentioned in the instructions here https://developers.facebook.com/docs/swift/login :

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as!

By the way, Grails have its data persistence build on top of Hibernate. How do you think JDO would help you in something Hibernate will not? I don't see why one would choose JDO over the default.

As far as JPA is concerned, I would recommend you to use JPA, Hibernate implementation of JPA which comes handy with Grails, and not any of the Hibernate specific feature, unless otherwise compelling.

If you want to avoid waiting for the calculation, you should use the multiprocessing package so that an independent process can do your expensive calculation.

You want a separate process which is calculating and enqueueing results.

Your "generator" can then simply dequeue the available results.

In single dispatch the function executed depends on just the object type. In double dispatch the function executed depends on the object type and a parameter.

In the following example, the function Area() is invoked using single dispatch, and Intersect() relies on double dispatch because it takes a Shape parameter.

class Circle; class Rectangle; class Shape { virtual double Area() = 0; // Single dispatch // ... virtual double Intersect(const Shape& s) = 0; // double dispatch, take a Shape argument virtual double Intersect(const Circle& s) = 0; virtual double Intersect(const Rectangle& s) = 0; }; struct Circle : public Shape { virtual double Area() { return /* pi*r*r */; } virtual double Intersect(const Shape& s); { return s.Intersect(*this) ; } virtual double Intersect(const Circle& s); { /*circle-circle*/ } virtual double Intersect(const Rectangle& s); { /*circle-rectangle*/ } };

The example is based on this article.

You can use toDate() functions that are builded inside Cassandra

For example SELECT toDate(columTimeUUID) FROM YourTable will give you a date formated as : YYYY-MM-DD

However, it works for Cassandra versions greater than 2.2

16594155 0 How to pass parameters in proper manner in C#?

I have stored procedure as below:

ALTER PROCEDURE [dbo].[Insert_tblCustomer] -- Add the parameters for the stored procedure here @Username varchar(20) = null, @Password varchar(20)= null, @UserType varchar(20)='User', @FirstName varchar(50)=null, @LastName varchar(50)=null, @DateOfBirth varchar(50)=null, @Gender varchar(10)=null, @Unit_No int = null, @St_No int=null, @St_Name varchar(20)=null, @Suburb varchar(20)=null, @State varchar(20)=null, @Postcode int=null, @Email varchar(50)='', @Phone varchar(15)=null

AS... and There are 5 fields i.e. username,password,firstname,lastname and email are must fields. Now from c#, I am trying this :

dbConnection target = new dbConnection(); // TODO: Initialize to an appropriate value string _query = string.Empty; // TODO: Initialize to an appropriate value SqlParameter[] param = new SqlParameter[5]; // TODO: Initialize to an appropriate value param[0] = new SqlParameter("@Username", "hakoo"); param[1] = new SqlParameter("@Password", "hakoo"); param[2] = new SqlParameter("@FirstName", "Hakoo"); param[3] = new SqlParameter("@LastName", "Hakoo"); param[4] = new SqlParameter("@Email", "haks@abc.com"); bool expected = true; // TODO: Initialize to an appropriate value bool actual; actual = target.Execute_InsertQuery("dbo.Insert_tblCustomer", param);

But, I am getting Assertfail exception. I am newbie to use stored procedures with test. Can anyone correct me where I am wrong?

"Added Assert part"

bool expected = true; // TODO: Initialize to an appropriate value bool actual; actual = target.Execute_InsertQuery("dbo.Insert_tblCustomer", param);

dbConnection is my created core class, where I am putting generic query :

public bool Execute_InsertQuery(string _query, SqlParameter[] param) { try { SqlCommand cmd = new SqlCommand(); cmd.Connection = OpenConnection(); cmd.CommandText = _query; cmd.Parameters.AddRange(param); cmd.ExecuteNonQuery(); return true; } catch (Exception ex) { Console.Write(ex.StackTrace.ToString()); return false; } }

Update for getting Error : I tried to pass all parameters in this manner :

dbConnection c = new dbConnection(); System.Data.SqlClient.SqlParameter[] param = new System.Data.SqlClient.SqlParameter[15]; param[0] = new SqlParameter("@Username", "hakoo"); param[1] = new SqlParameter("@Password", "hakoo"); param[2] = new SqlParameter("@UserType", "User"); param[3] = new SqlParameter("@FirstName", "Hakoo"); param[4] = new SqlParameter("@LastName", "Hakoo"); param[5] = new SqlParameter("@DateOfBirth", "02/11/88"); param[6] = new SqlParameter("@Gender", ""); param[7] = new SqlParameter("@Unit_No", null); param[8] = new SqlParameter("@St_No", 25); param[9] = new SqlParameter("@St_Name", "anc st"); param[10] = new SqlParameter("@Suburb", "ancst"); param[11] = new SqlParameter("@State", "assadd@few"); param[12] = new SqlParameter("@Postcode", 2615); param[13] = new SqlParameter("@Email", "abc@def.com.au"); param[14] = new SqlParameter("@Phone", "165103548"); c.Execute_InsertQuery("dbo.Insert_tblCustomer", param);

But for this, I am getting this error :

The parameterized query '(@Username nvarchar(5),@Password nvarchar(5),@UserType nvarchar(' expects the parameter '@Unit_No', which was not supplied. I can execute this Store procedure in SQL Server.

29838931 0 AWS iOS SDK TLS Support

Related Question: AWS S3 Disabling SSLv3 Support

This is more of an inquiry for the mobile iOS SDK. Wondering what I have to do or where to start since am a bit clueless.

Also just received a notice that Amazon is deprecating SSLv3 and that I need to modify my requests to use TLS.

This is an older iOS app still using the AWS iOS SDK 1.7 version. This basically just accesses S3 Buckets for both upload and download of images.

Now is this normally handled already by the library or do I have to update to the v2 library, thereby dropping iOS 6 support. Or can it just be through code changes, etc.

It is used to inform the compiler to disable C++ name mangling for the functions defined within the braces. http://en.wikipedia.org/wiki/Name_mangling

7646493 0

The compiler is picking the IEnumerator<int> GetEnumerator method by following the rules in 8.8.4 of the C# language specification which first looks for an accessible GetEnumerator() method on the BarList type. The only one of those which is available is the one returning IEnumerator<int>.

If you had made that method use explicit interface implementation as well, then it would have gone onto the later stages of section 8.8.4, which states that if there is more than one type T such that there is an implicit conversion from the expression type (BarList here) to IEnumerable<T> then an error is produced.

I would say this is a confusing design - I would probably add properties or methods to retrieve appropriate "views" on the data.

Perhaps the confusion is between a variable and a field. A field is a property that is associated with an object. A variable exists only in the context of a method. When the method finishes, the variable vanishes.

A field, on the other hand, looks exactly the same as a variable except that a field is declared outside of any method, directly on the class "body". Fields and methods are declared at the same hierarchical level. You can see that on Eclipse. Check the "outline" view.

If you need several methods to read and write the same "variable", then what you need is a field. I hope this clarifies.

I believe that the way 'iisnode' works is that it intercepts requests for files with ".js" extension. I do not think it can be set up to run same way as you would run it using node or nodemon.

In my case I set up a production Node.js server with IIS by doing the following:

I set up my port in server.js to run on different port (say 81) so that it does not interfere with IIS.
I set up node to run in a service, so that it auto-restarts when server restarts, console window will not get closed accidently, etc (there are few options you can use - for example http://nssm.cc/ but we wrote our own wrapper service).
I set up forwarding from IIS to that node server - that way I could still use port 80 for the site externally and I was able to use host header filtering (there are multiple sites running on one server)

The entry is completely optional, but the bug you are pointing to is related to compilation, not runtime, so it is highly unlikely that this is the problem.

Application Servers are often very file hungry, and if nothing has been done to increase the limit of open files, the default may not be high enough.

On CentOS for example, we found that even in QA (not load testing, just functional testing) a server could max out its ulimit with JBoss 4.2.

EDIT: The only thing wrong with the code that you posted in terms of holding files open is that you should use finally to close your stream. In a server application, it could be that this code often throws an exception, causing files to not be closed (because you don't close them in a finally) and over time those open file handles add up. There are other issues in how you are doing it (like relying on the available() to determine the size of the byte array), but that should not affect your problem.

Another possibility is that under *nix systems sockets consume the same resource as files, so it could be that you have too many sockets (above what the system is configured to allow) open, causing this code to be unable to execute.

Session is a good way to store and remember data but why complicate things? Consider if the form has many fields, developer has to store lots of values in session. Why not simply print or echo.

Example:

Form is submitted with input ssName and hidden field ssAct with value of send

Get the ssName and ssAct on form submit

$ssAct=$_REQUEST["ssAct"]; $ssName=$_REQUEST["ssName"];

and the form

<input type="text" name="ssName" value="<?php if($ssAct=='send' && $ssName!='') { echo "$ssName"; } ?>"> <input type="hidden" name="ssAct" value="send">

On submit name will be echoed if it was submitted and was not empty.

24769785 0 More efficient way of running multiple update queries on an Access database?

I have multiple queries like this right now which involve updating different fields of the same row in an Access database:

//Update database string updatequery = "UPDATE [table] SET [Last10Attempts] = ? WHERE id = ?"; OleDbConnection con = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;" + @"Data Source=" + "database.accdb"); con.Open(); OleDbDataAdapter da = new OleDbDataAdapter(updatequery, con); var accessUpdateCommand = new OleDbCommand(updatequery, con); accessUpdateCommand.Parameters.AddWithValue("Last10Attempts", last10attempts); accessUpdateCommand.Parameters.AddWithValue("ID", currentid + 1); da.UpdateCommand = accessUpdateCommand; da.UpdateCommand.ExecuteNonQuery(); //update last10attemptssum updatequery = "UPDATE [table] SET [Last10AttemptsSum] = ?

I was wondering if there is a more efficient way of running these update queries - ie. combining them into one query.

34594701 0 delete section at indexPath swift

I have an array which populates a table view - myPosts.

The first row of the table view is not part of the array.

Each row is its own section (with its own custom footer)

I am trying to perform a delete with the following code:

 func tableView(profileTableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) { if (editingStyle == UITableViewCellEditingStyle.Delete) { myPosts?.removeAtIndex(indexPath.section - 1) profileTableView.beginUpdates() let indexSet = NSMutableIndexSet() indexSet.addIndex(indexPath.section - 1) profileTableView.deleteSections(indexSet, withRowAnimation: UITableViewRowAnimation.Automatic) profileTableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.Automatic) profileTableView.endUpdates() ... WS Call ... } }

And the log is reporting the following:

 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (1) must be equal to the number of rows contained in that section before the update (1), plus or minus the number of rows inserted or deleted from that section (0 inserted, 1 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).'

Obviously the issue is related to 0 moved in, 0 moved out but I don't understand why that is? or what the solution would be?

number of sections in tableView is as follows:

func numberOfSectionsInTableView(tableView: UITableView) -> Int { if self.myPosts == nil { return 1 } return self.myPosts!.count + 1 }

The setInterval executes after the function is run, by which point i has incremented to 4. You should create a closure over the element to preserve it

setInterval(runnable(elements[i], text, target_date), 1000); // also pass target_date since it is needed function runnable(el, text, target_date) { return function () { // find the amount of "seconds" between now and target var current_date = new Date().getTime(); var seconds_left = (target_date - current_date) / 1000; // do some time calculations days = parseInt(seconds_left / 86400); seconds_left = seconds_left % 86400; hours = parseInt(seconds_left / 3600); seconds_left = seconds_left % 3600; minutes = parseInt(seconds_left / 60); seconds = parseInt(seconds_left % 60); // format countdown string + set tag value el.innerHTML = text + days + "d, " + hours + "h, " + minutes + "m, " + seconds + "s"; } }

10809728 0 Backbone Marionette CompositeView "Event Zombie"

I have a fairly simple table created using a Backbone Marionette CompositeView. The only requirements on this table are that it display data and allow the user to sort it by clicking the header row. When the table is sorted, the columns used to sort the header column are tagged with classes to allow an arrow to be displayed using CSS (e.g. 'class="sort asc"').

Here is the problem: When the header row is clicked, the element that is passed to the callback (via event.target) is not part of the table that is on the DOM. Instead, using Chrome's debugging tools it appears that the target element is actually part of the template script block, and not the element the user actually sees.

The best work-around I've got right now is to lookup the element actually attached to the DOM by retrieving unique info from its clone in the template.

Here's the composite view code (borrowed from one of Derick Bailey's sample Fiddle's):

// The grid view var GridView = Backbone.Marionette.CompositeView.extend({ tagName: "table", template: "#grid-template", itemView: GridRow, events: { 'click th': 'doSort' }, doSort: function(event) { var target = $(event.target); this.collection.sortByField(target.data('sortby')); target.parent('tr').find('.sort').removeAttr('class'); target.addClass('sort ' + this.collection.sortdir); debugger; // NOTE: no change to elements in the DOM. WTH? target = this.$('[data-sortby=' + target.data('sortby') + ']'); target.parent('tr').find('.sort').removeAttr('class'); target.addClass('sort ' + this.collection.sortdir); debugger; // NOTE: DOM updated. }, appendHtml: function(collectionView, itemView) { collectionView.$("tbody").append(itemView.el); } });

The template is simple as well:

<script id="grid-template" type="text/template"> <thead> <tr> <th data-sortby="username">Username</th> <th data-sortby="fullname">Full Name</th> </tr> </thead> <tbody></tbody> </script>

A fork of Derek's original demo Fiddle modified to demonstrate the problem can be found here: http://jsfiddle.net/ccamarat/9stvM/14/

I've meandered a bit. My question is, I appear to have a spawned a Zombie View of sorts; is this a jQuery/Backbone/Underscore bug, or am I simply going about this all wrong?

** EDIT ** Here's the console output showing the different parent hierarchies of the two elements:

console.log(target, targetb): [<th data-sortby="username" class="sort asc">Username</th>] [<th data-sortby="username">Username</th>] console.log(target.parents(), targetb.parents()): [<tr>…</tr>, <thead>…</thead>] [<tr>…</tr>, <thead>…</thead>, <table>…</table>, <div id="grid">…</div>, <body>…</body>, <html>…</html>] console.log(target === targetb): false

PHP is a server-side language and you won't be able to load it up in a web browser just like that. You'll have to use a web server, like WAMP or XAMPP for example.

Make sure of these things first:

that PHP is installed and running on your computer
that the file extension is .php
that you're accessing the php file with something like localhost/yourfile.php and not file://yourfile.php
that the permission for your files is correct (644 or 755 would be enough, I think)

Hope this helps.

7932272 0 Could these patterns be matched by regular expression or context free grammar?

This is an exercise of compiler. We are asked if it's possible to match the following patterns with regular expression or context free grammar:

n 'a' followed by n 'b', like 'aabb'
palindrome, like 'abbccbba'
n 'a', then n 'b', then n 'c', like 'aabbcc'

Note that n could be any positive integer. (Otherwise it's too simple)

Only 3 character 'abc' could appear in the text to parse.

I'm confused because as far as I can see, non of these patterns can be described by regular expression and context free grammar.

1. Your function signature takes 3 arguments, and you only supply 1. How it compiles, I do not know, as I don't think it should.

2. The CalculateAirTime function prints a variable before calculating it. You first do this: printf("Total air time: %f\n", time); , and then calculate the actual air time: time = ((2*velocity)*sin(angle)/GRAVITY);

3. As an advice, since the CalculateAirTime function needs velocity and angle to return a calculated time, do not pass time as a parameter. It's useless. You can either declare a double variable inside the function or directly return the calculated time.

Replace double CalculateAirTime(double velocity, double angle, double time){...} with double CalculateAirTime(double velocity, double angle){...}

*EDIT! For clarity purposes, here is how I would probably write your program:**

#include <stdio.h> #include <math.h> #define PI 3.14159265358979323846 #define GRAVITY 9.8 /* I renamed some variables. Just from the variable names, I think you do not understand the solution for this "air time" problem well. I might be mistaken tough. If you have any questions, please ask them. You are not leaving this place until you fully understand what is happening. */ // Function DECLARATION: double CalculateAirTime(double Initial_Velocity, double Launch_Angle); int main(void) { // variables double Initial_Velocity; double Launch_Angle; // Initial_Velocity = 20.0 should work aswell. This is called a cast. You will learn about it later Initial_Velocity = (double)(20.0); // Converting 45 degrees to radians, because the sin() library function works with radians Launch_Angle = (double)((45.0/180.0)*PI); //Call function using our declared values as input CalculateAirTime(Initial_Velocity,Launch_Angle); return 0; } // Function DEFINITION //Try to use the same name for paramaters here, as you did in the declaration! double CalculateAirTime(double Initial_Velocity, double Launch_Angle) { double Air_Time; Air_Time = (double)((2*Initial_Velocity)*sin(Launch_Angle)/GRAVITY); printf("Total air time: %f\n", Air_Time)); return time; }

No, null values are not set to the default, as null is itself a valid value for a variable or field in SQL.

To ensure a parameter gets its default value, do not pass in the parameter at all. So for your proc:

-- @myVar will get default EXEC TestVarcharMaxIsNull -- @myVar will be null EXEC TestVarcharMaxIsNull @myVar=NULL -- @myVar will be "Hello" EXEC TestVarcharMaxIsNull @myVar='Hello'

35408345 0 Need advice to choose graph database

I'm looking for options for graph database to be used in a project. I expect to have ~100000 writes (vertix + edge) per day. And much less reads (several times per hour). The most frequent query takes 2 edges depth tracing that I expect to return ~10-20 result nodes. I don't have experience with graph databases and want to work with gremlin to be able to switch to another graph database if needed. Now I consider 2 possibilities: neo4j and Titan.

As I can see there is enough community, information and tools for Neo4j, so I'd prefer to start from it. Their capacity numbers should be enough for our needs (∼ 34 billion nodes, ∼ 34 billion edges). But I'm not sure which hardware requirements will I face in this case. Also I didn't see any parallelisation options for their queries.

On the other hand Titan is built for horizontal scalability and has integrations with intensively parallel tools like spark. So I can expect that hardware requirements can scale in a linear way. But there is much less information/community/tools for Titan.

I'll be glad to hear your suggestions

16255864 0 uncrustify adds space between double-paranthesis (C/Objective-C)

I'm having a very peculiar issue with uncrustify (v0.60) that no option seems to affect. The issue only occurs when there are parenthesis enclosed within parenthesis:

// from a C header file: #define BEGIN_STACK_MODIFY(L) int __index = lua_gettop( (L) ); ^ ^ // from an ObjC (.m) implementation file: if ( (self = [super init]) ) ^ ^

I want to reformat those to look like this, but uncrustify always adds those spaces between parenthesis (when I manually reformat to the code below, uncrustify will reformat it to the version above, so it's not just being ignored by uncrustify):

// from an ObjC header file: #define BEGIN_STACK_MODIFY(L) int __index = lua_gettop((L)); // from an ObjC (.m) implementation file: if ((self = [super init]))

I used UncrustifyX to check all (well, a great number of) variations of possibly related settings for spaces and parenthesis with no luck.

You can check my uncrustify config file here on gist.

If you have any idea what settings I should try, or perhaps settings that may be in conflict with each other, I'd be happy to test it.

17095480 0 Get Host of HttpResponseMessage in Windows Store App

I have a Windows Store App (C#) where I am sending a HttpRequest and I want to check if the response I am getting is from a Captive/Limited Access Network or from the actual host specified in the HttpRequest.

So lets say I am sending a request to www.serverA.com I look at the response of that request and determine if it was success based on the status code.

Imagine the same scenario in a captive network(airport networks/starbucks where they redirect you to a login page):

I am sending a request to www.serverA.com
My request gets redirected to www.serverB.com/AirPortLoginPage
I get back a response that the AirportLoginPage loaded successfully with a 200 response
My code sees that as a success because of the 200 status code, but I wanted to know if my original request was successful

So, is there a way to determine the host of the server where the Response Message is coming from?

StringBuffer - introduced in JDK 1.0 - is thread safe (all of its methods are synchronized), while StringBuilder - since JDK 1.5 - is not. Thus it is recommended to use the latter under normal circumstances.

StringTokenizer is meant for a whole different purpose then the former two: cutting strings into pieces, rather than assembling. As @Henning noted, it is also "retired" since JDK 1.5 - it is recommended to use String.split instead.

The results:

So, charAt is the fastest one. BTW, grep -o ',' | wc -l took 7402 ms.

34386337 0 Documenting Spring's login/logout API in Swagger

I am developing demo REST service using Spring Boot where user has to login in order to to perform certain subset of operations. After adding Swagger UI (using springfox library) with that simple configuration:

@Bean public Docket docApi() { return new Docket(DocumentationType.SWAGGER_2) .select() .apis(any()) .paths(PathSelectors.ant("/api/**")) .build() .pathMapping("/") .apiInfo(apiInfo()) .directModelSubstitute(LocalDate.class, String.class) .useDefaultResponseMessages(true) .enableUrlTemplating(true); }

I end up with all apis with all operations listed on Swagger UI page. Unfortunately I don't have login/logout endpoints listed among them.

The problem is that part of that operations cannot be performed via Swagger UI built-in form (I find it really nice feature and would like make it work), because user is not logged in. Is there any solution to that problem? Can I define manually some endpoints in Swagger?

If there was a form to submit credentials (i.e. login/logout endpoints) I could perform authorization before using that secured endpoints. Then, Swagger user could extract token/sessionid from response and paste it to custom query parameter defined via @ApiImplicitParams.

Below you can find my security configuration:

@Override protected void configure(HttpSecurity http) throws Exception { http .formLogin() .loginProcessingUrl("/api/login") .usernameParameter("username") .passwordParameter("password") .successHandler(new CustomAuthenticationSuccessHandler()) .failureHandler(new CustomAuthenticationFailureHandler()) .permitAll() .and() .logout() .logoutUrl("/api/logout") .logoutSuccessHandler(new CustomLogoutSuccessHandler()) .deleteCookies("JSESSIONID") .permitAll() .and() .csrf() .disable() .exceptionHandling() .authenticationEntryPoint(new CustomAuthenticationEntryPoint()) .and() .authorizeRequests() .and() .headers() .frameOptions() .disable(); } @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth .userDetailsService(userDetailsService) .passwordEncoder(passwordEncoder()); }

If I understand correctly, the behavior you want is to drop each of your columns market with class="col" into a row, when your media query for small screens comes into effect.

First of all, Outlook will strip out all in-line styling (as you noticed using F12), so best to double that up using the equivalent html attributes for each of your elements.

Secondly, max-width is not supported by Outlook (and Lotus Notes 8 & 8.5), so you will need to wrap each of your <table>s that are inside you 'col' columns into conditional code which creates a table with a set width to hold everything in, that targets IE and Microsoft Outlook. You will need to use something like:

<!--[if (gte mso 9)|(IE)]> <table width="525" align="left" cellpadding="0" cellspacing="0" border="0"> <tr> <td> <![endif]--> <table style="table-layout: auto; background-color: white; padding-left: 10px; padding-right: 10px;" border="0" cellpadding="0" cellspacing="0" width="100%"> <tbody> <tr> <td style="padding-top: 15px;padding-right: 20px;padding-bottom: 0;padding-left: 20px;font-size: 26px;line-height: 30px;font-weight:400; font-family: Arial, sans-serif; color: #0056a6;" align="left"><img src="/resources/handlers/dcimage.ashx" style="height: auto; display: inline;" border="0">,</td> </tr> <tr> <td style="padding-top: 15px;padding-right: 20px;padding-bottom: 20px;padding-left: 20px; font-size: 14px; font-weight:normal; line-height: 14px; font-family: Arial, sans-serif; color: #2d353d;" align="left"> LOREM IPSUM </td> </tr> </tbody> </table> <!--[if (gte mso 9)|(IE)]> </td> </tr> </table> <![endif]-->

You can have multiple programs in a shader, but not the other way around.

To make multiple combinations, the easiest way is to store each major chunk as a fragment with a named entry point, then include them from another program or combine them at runtime into a single program, calling them in the order you need. That can get messy though, when handling input and outputs.

You can use multiple passes, with different effects and programs in each pass. That has some additional overhead, but can be easier to set up.

Dates and times in Excel are stored as floating point numbers. Dates are days since 1900 (a date of 1 is 01/01/1900), and times are fractions of a day (so 0.5 is 12 hours).

Depending on what format you need the value to be in before you put it in a database, then you might just want to take the numeric value and multiple by 24 to get the hours and fractional hours, eg:

double time = cell.getNumericCellValue() * 24; int hours = (int)time; int minutes = (time - hours) * 60;

Alternately, if you want a string, then the DataFormatter class will happily format a value of 1.5 as HH:MM to 36:00

25249191 0 For Each Row in Range - Incorrect Row Iteration

I'm creating a single-column index file from multi-row/-cell source data in Excel. I have two worksheets - a source and destination - in a single workbook. Iterating through each row (11 in dev, ~15,000 in prod) of the source worksheet the For Each loop I wrote should:

Find the first empty cell in Column A of the destination worksheet
Use LastCell.Value = to input a set value in that cell
Use LastCell.Offset(r, c).Value = to pair a set value with a copied value from each cell in a single row of the source worksheet to the next destination cell down. There are eight to be copied and a ninth that is set

The loop works perfectly once, then fails to iterate to the next row. Each subsequent loop shifts copied values up by one and leaves the set values, with blanks, in place. It does this once for each cell in the source row and only after that does it move on to the next row down.

When I say set value I'm referring to what is in quotes, and copied values are those of the Row.Offset.

The code is:

Sub Export_Index_File() Dim wb As Workbook Dim ws1 As Worksheet, ws2 As Worksheet Dim sr As Range Set wb = ActiveWorkbook Set ws1 = wb.Worksheets("Source Data") Set ws2 = wb.Worksheets("Index File") Set sr = ws1.Range("A2:H13") For Each Row In sr.Cells Set LastCell = ws2.Cells(ws2.Rows.Count, "A").End(xlUp).Offset(1) LastCell.Value = "Begin Doc" LastCell.Offset(1, 0).Value = "Account Number: " & Row.Offset(0, 0).Value LastCell.Offset(2, 0).Value = "Account Type: " & Row.Offset(0, 1).Value LastCell.Offset(3, 0).Value = "Date: " & Row.Offset(0, 2).Value LastCell.Offset(4, 0).Value = "Doc Type: " & Row.Offset(0, 3).Value LastCell.Offset(5, 0).Value = "File Path: " & Row.Offset(0, 4).Value LastCell.Offset(6, 0).Value = "Institution: " & Row.Offset(0, 5).Value LastCell.Offset(7, 0).Value = "Name: " & Row.Offset(0, 6).Value LastCell.Offset(8, 0).Value = "TIN: " & Row.Offset(0, 7).Value LastCell.Offset(9, 0).Value = "End Doc" Next Row End Sub

Here are two output examples. Successful on the left, unsuccessful on the right:

Begin Doc |Begin Doc Account Number: 123456 |Account Number: Checking Account Type: Checking |Account Type:01/01/2001 Date: 01/01/2001 |Date: Statement Doc Type: Statement |Doc Type: 123456.pdf File Path: 123456.pdf |File Path: 123 Institution: 123 |Institution: Jane Doe Name: Jane Doe |Name: 123-45-6789 TIN: 123-45-6789 |TIN: End Doc |End Doc

Notice the one-line shift up. To fix this, I changed the loop to read For Each Row In sr.Rows but received Type 13 Mismatch errors.

I copied this code from a working spreadsheet before expanding it to include more rows. It is nearly identical to the working code. What am I doing wrong?

Yes this is possible, you simply have to specify the transport when initializing the Bus:

For the documentation part, I suggest you take a look on github: https://github.com/NServiceBus/NServiceBus/tree/master/Samples/Azure

Note that most of these samples are meant to run in Windows Azure, hence the use of the AzureConfigurationSource. This won't work when you're running on premise since it uses settings from the RoleEnvironment. Don't use AzureConfigurationSource when working on premise.

Use the standard vibrate method with patterns parameter

public abstract void vibrate (long[] pattern, int repeat)

Pass in an array of ints that are the durations for which to turn on or off the vibrator in milliseconds. The first value indicates the number of milliseconds to wait before turning the vibrator on. The next value indicates the number of milliseconds for which to keep the vibrator on before turning it off. Subsequent values alternate between durations in milliseconds to turn the vibrator off or to turn the vibrator on.

To cause the pattern to repeat, pass the index into the pattern array at which to start the repeat, or -1 to disable repeating.

This method requires the caller to hold the permission VIBRATE.

Parameters pattern an array of longs of times for which to turn the vibrator on or off. repeat the index into pattern at which to repeat, or -1 if you don't want to repeat.

variable: A variable name to access the data as properties, instead of using a with statement

And is it possible to compile settings into a template?

Yes. Simply pass any falsy value (null, undefined, false, …) for data and the method will return a template function instead of rendering it right away.

In fact, your question can be merely resolved through an underrated characteristic of box-shadow:

The ‘box-shadow’ property attaches one or more drop-shadows to the box. The property takes a comma-separated list of shadows, ordered front to back. Each shadow is given as a <shadow>, represented by 2-4 length values, an optional color, and an optional ‘inset’ keyword.
<shadow> = inset? && {2,4} && ?

Your current box-shadow: 0 2px 10px 0 rgba(0, 0, 0, 0.16) is only one of the possible <shadow>s as stated above.

You can simply prepend it with a first (so front) <shadow> with the desired characteristics, like:
box-shadow: #fff 0 -5px, 0 2px 10px 0 rgba(0, 0, 0, 0.16), where the 1st instance has:

#fff has to be the same color as the master <ul> color
0 makes no horizontal (right) shadow
-5pxmakes a vertical (natively down, but here up since the minus sign) shadow, which is just what you need to hide the top shadow generated by your previous unique (and now 2nd) instance

Then you have to manage with your red <ul> border-bottom, because now it is hidden also: it's up to you to imagine which method to use for that.

10288364 0 MySQL Find Full Name Across Two Rows

I have a MySQL table where I'm trying to find a person by his full name. The problem is that first and last name are stored on two separate rows in the table as shown here:

+-----------------+-------------+-------------+--------------+ | submit_time | form_name | field_name | field_value | +-----------------+-------------+-------------+--------------+ | 1323463601.0947 | Online Form | firstname | Paulo | | 1323463601.0947 | Online Form | lastname | Hill | +-----------------+-------------+-------------+--------------+

How can I construct a query that will get a single result (if possible) by searching for Paulo Hill?

Also, the submit_time column should have the same value for both rows--that will be the one column value that is unique in the table.

Simply use "where". For instance, to get all the "PassedStudents":

var passedStudents = from student in StudentList where student.StatusResult == ResultsStatus.PassedStudent select student; foreach (var student in passedStudents) { Console.WriteLine("[{0}.] {1} passed.", student.Id, student.Detail.Name); }

You can also write the query using lambda expressions:

var passedStudents = StudentList.Where(student => student.StatusResult == ResultsStatus.PassedStudent);

Apache Storm is a distributed realtime computation system (source: project website.

CEP is complex event processing concerned with tracking and analyzing (processing) streams of information (data) about things that happen (events) and deriving a conclusion from them. (Source:wiki)

They are two different things. Storm does not itself analyze unless you deploy some code that analyzes. That makes the code doing CEP, and not Storm. You can do CEP using Storm yes, or can do CEP u using JMS or whichever else.

Actors such as Akka or Orleans are also candidate places to host event analysis code that does CEP.

My take is that __size and __align fields specify (guess what :-) ) the size and alignment of the structure independently of the __data structure. So, the data can be of a less size and have less alignment requirements, it can be modified freely without breaking these basic assumptions about it. And vice-versa, these basic characteristics can be changed without altering the data structure, like here.

It is important to note that if the size of the __data becomes bigger than specified by __SIZEOF_PTHREAD_MUTEX_T, an assertion fails in __pthread_mutex_init():

assert (sizeof (pthread_mutex_t) <= __SIZEOF_PTHREAD_MUTEX_T);

Consider this assertion as an essential part of this approach.

So, the conclusion is that this was done not to hide the implementation details, but to make the data structure more predictable and manageable. It is very important for a widely-used library which should care a lot about backward compatibility and performance impact to other codes from the changes which can be made to this structure.

If the XML you're trying to parse is what you've posted here, it's invalid since

XML documents must contain one root element that is the parent of all other elements:

http://www.w3schools.com/xml/xml_syntax.asp

(and yours doesn't, and parsing such string fails with Exception: String could not be parsed as XML in ...).

So your XML should be:

<?xml version="1.0" ?> <users> <user> <name> foo </name> <token> jfhsjfhksdjfhsjkfhksjfsdk </token> <connection> <host> localhost </host> <username> root </username> <dbName> Test </dbName> <dbPass> 123456789 </dbPass> </connection> </user> <user> ... same structure... </user> </users>

And you don't need to iterate through the collection

// $nodes is SimpleXMLElement $user = $nodes->user[0]; if($user->token) return $user->token->__toString();

Per the MSDN documentation the valid values for mode are:

On: Specifies that custom errors are enabled. If no defaultRedirect attribute is specified, users see a generic error. The custom errors are shown to the remote clients and to the local host.

Off Specifies that custom errors are disabled. The detailed ASP.NET errors are shown to the remote clients and to the local host.

RemoteOnly Specifies that custom errors are shown only to the remote clients, and that ASP.NET errors are shown to the local host. This is the default value.

The default is RemoteOnly.

Just overcame a similar issue. JBoss 5 and 6 are much more strict with DTD validation than earlier versions, especially the 4.x series. Your jboss.xml file is failing DTD validation, either because element order is incorrect, or there are elements which don't validate against the DTD.

Take a look at the order of the XML elements in standardjboss.xml, and you'll see how your jboss.xml file differs.

Ok, here's the scoop. QTimer, for reason only known to the designers of QT, inherits the context of the parent of the thread. Not the context of the thread it's launched from. So when the timer goes off, and you send a message from the slot it called, you're not in the thread's context, you're in the parents context.

You also can't launch a thread that is child of THAT thread, so that you can fire a timer that will actually be in the thread you want. Qt won't let it run.

So, spend some memory, make a queue, load the message into the queue from elsewhere, watch the queue in the thread that owns the TCP port, and send em when ya got em. That works.

The TCP protocol described in RFC 793 describes the terms socket and connection. A socket is an IP address and port number pair. A connection is a pair of sockets. In this sense, the same socket can be used for multiple connections. It is in this sense that the socket being passed to accept() is being used. Since a socket can be used for multiple connections, and the socket passed to accept() represents that socket, the API creates a new socket to represent the connection.

If you just want an easy way to make sure the one socket that accept() creates for you is the same socket you used to do the accept() call on, then use a wrapper FTW:

int accept_one (int accept_sock, struct sockaddr *addr, socklen_t *addrlen) { int sock = accept(accept_sock, addr, addrlen); if (sock >= 0) { dup2(sock, accept_sock); close(sock); sock = accept_sock; } return sock; }

If you are wanting a way for a client and server to connect to each other, without creating any more than just one socket on each side, such an API does exist. The API is connect(), and it succeeds when you achieve a simultaneous open.

static struct sockaddr_in server_addr; static struct sockaddr_in client_addr; void init_addr (struct sockaddr_in *addr, short port) { struct sockaddr_in tmp = { .sin_family = AF_INET, .sin_port = htons(port), .sin_addr = { htonl(INADDR_LOOPBACK) } }; *addr = tmp; } void connect_accept (int sock, struct sockaddr_in *from, struct sockaddr_in *to) { const int one = 1; int r; setsockopt(sock, SOL_SOCKET, SO_REUSEADDR, &one, sizeof(one)); bind(sock, (struct sockaddr *)from, sizeof(*from)); do r = connect(sock, (struct sockaddr *)to, sizeof(*to)); while (r != 0); } void do_peer (char *who, const char *msg, size_t len, struct sockaddr_in *from, struct sockaddr_in *to) { int sock = socket(PF_INET, SOCK_STREAM, 0); connect_accept(sock, from, to); write(sock, msg, len-1); shutdown(sock, SHUT_WR); char buf[256]; int r = read(sock, buf, sizeof(buf)); close(sock); if (r > 0) printf("%s received: %.*s%s", who, r, buf, buf[r-1] == '\n' ? "" : "...\n"); else if (r < 0) perror("read"); } void do_client () { const char msg[] = "client says hi\n"; do_peer("client", msg, sizeof(msg), &client_addr, &server_addr); } void do_server () { const char msg[] = "server says hi\n"; do_peer("server", msg, sizeof(msg), &server_addr, &client_addr); } int main () { init_addr(&server_addr, 4321); init_addr(&client_addr, 4322); pid_t p = fork(); switch (p) { case 0: do_client(); break; case -1: perror("fork"); exit(EXIT_FAILURE); default: do_server(); waitpid(p, 0, 0); } return 0; }

If instead you are worried about performance issues, I believe those worries are misguided. Using the TCP protocol, you already have to wait at least one full round trip on the network between the client and the server, so the extra overhead of dealing with another socket is negligible. A possible case where you might care about that overhead is if the client and server are on the same machine, but even then, it is only an issue if the connections are very short lived. If the connections are so short lived, then it would probably be better to redesign your solution to either use a cheaper communication medium (e.g., shared memory), or apply framing on your data and use a persistent connection.

The various Central Banks, for example the ECB, provide Forex rates free to the public.

There is a PEAR package for Forex Rates and it is also not hard to code it yourself. Since the data is usually updated on a daily basis, you will want to add caching, so as not to hammer the bank's server.

However, if your application is doing any time-critical conversion, you should resort to a commercial service, as these usually update more frequently. I think Yahoo and Google have a financial API and someone already mentioned XE.com.

8328932 0 Eclipse toolbar with multiple rows

In my RCP app, I contribute several items to the main toolbar. The easy question now is: How do I make Eclipse lay them out so that they appear in a second row, just under the normal toolbar? Or can I add an additional toolbar that appears just under the main bar? Right now, they just appear somewhere between the other items contributed by other plugins. I tried a lot of stuff and searched a long time, couldn't find any answer though.

6053897 1 how to assign an sql value to this python variable

ok i got this as simple as i can, everythings working and i need one last thing before I'm done with this issue i am using sqlite3 module in python i also have very limited sql expierance

the problem- i need to take the only value out of an sql table; the tablename is saves and the row id is 0 the name of the row is lvl. i need to then assign this as the value of the python variable lvl. Then on closure of the program i need to update the sql table with the current value of the python variable lvl (it will take the place of the data i just retrieved--there will also be numerous operations in between).

My code for assigning the value of the python Variable

conn = sql.connect('databaserm/database') curs = conn.cursor() curs.execute('SELECT 0 FROM saves') lvl = curs.fetchone() conn.commit conn.close()

after running this i get the output None

and my code for adding data to the database on closure

 elif choice == q: if choice == q: cn = sqlite3.connect('/databaserm/database') curs = cn.cursor() curs.execute('INSERT INTO saves (lvl) VALUES (?)', lvl) cn.commit cn.close() loop1 = 0 loop = 10000 print "Goodbye!" sys.exit(0)

after running this with a preloaded database and the previous code ommited i get a connection error

i would be overjoyed at any help i'm offered and hope to work out a solution to this soon

Yes this is possible. But one class needs to know the other class. Try it like this:

Class1 { public ExampleInstance Instance { get; set; } //Create your Class2 object here with Class2 SecondClassObject = new Class2(this) } Class2 { private Class1 MyCreator; public Class2(Class1 Creator) { this.MyCreator = Creator; } //Now you can use the object with: MyCreator.Instance }

Hope this helps.

What compiler did you use, I'm willing to bet this worked because whatever compiler you used didn't zero out unused stack variables after a return, you didn't get a seg fault because its still your stack. basically md was left on the stack which you are technically still allowed to address. The difference between the two is

largeObj md;

is a variable receiving a variable in its entirety.

largeObj& mdd = iReturnLargeObjects();

is a reference to a variable that due to a lazy compiler still exists.

23738860 0 ASP Identity 2.0.0 usermanager calling wrong method?

I have implemented a custom UserStore for my ASP MVC project (with Identity 2.0.0, which I use for it allows the use of integer keys).

The Usermanager is not custom implemented, but the Microsoft.AspNet.Identity.Usermanager implementation.

When I call:

IdentityResult result = await UserManager.CreateAsync(User, model.Password);

In my accountcontroller, the

public Task UpdateAsync(TUser user)

method is called instead of

 public Task CreateAsync(TUser user)

How could this be? Is it a known bug? Could I work around this?

936296 0 Where do you perform your validation?

Hopefully you'll see the problem I'm describing in the scenario below. If it's not clear, please let me know.

You've got an application that's broken into three layers,

front end UI layer, could be asp.net webform, or window (used for editing Person data)
middle tier business service layer, compiled into a dll (PersonServices)
data access layer, compiled into a dll (PersonRepository)

In my front end, I want to create a new Person object, set some properties, such as FirstName, LastName according to what has been entered in the UI by a user, and call PersonServices.AddPerson, passing the newly created Person. (AddPerson doesn't have to be static, this is just for simplicity, in any case the AddPerson will eventually call the Repository's AddPerson, which will then persist the data.)

Now the part I'd like to hear your opinion on is validation. Somewhere along the line, that newly created Person needs to be validated. You can do it on the client side, which would be simple, but what if I wanted to validate the Person in my PersonServices.AddPerson method. This would ensure any person I want to save would be validated and removes any dependancy on the UI layer doing the work. Or maybe, validate both in UI and in by business server layer. Sounds good so far right?

So, for simplicity, I'll update the PersonService.AddPerson method to perform the following validation checks - Check if FirstName and LastName are not empty - Ensure this new Person doesn't already exist in my repository

And this method will return True if all validation passes and the Person is persisted, False if Validation fails or if the Person is not persisted.

But this Boolean value that AddPerson returns isn't enough for me at the UI layer to give the user a clear reason why the save process failed. So what's a lonely developer to do? Ultimately, I'd like the AddPerson method to be able to ensure what its about to save is valid, and if not, be able to communicate the reasons why it's not invalid to my UI layer.

Just to get your juices flowing, some ways of solving this could be: (Some of these solutions, in my opinion, suck, but I'm just putting them there so you get an understanding of what I'm trying to solve)

Instead of AddPerson returning a boolean, it can return an int (i.e. 0 = Success, Non Zero equals failure and the number indicates the reason why it failed.
In AddPerson, throw custom exceptions when validation fails. Each type of custom exception would have its own error message. In addition, each custom exception would be unique enough to catch in the UI layer
Have AddPerson return some sort of custom class that would have properties indicating whether validation passed or failed, and if it did fail, what were the reasons
Not sure if this can be done in VB or C#, but attach some sort of property to the Person and its underlying properties. This "attached" property could contain things like validation info
Insert your idea or pattern here
And maybe another here

Apologies for the long winded question, but I definately like to hear your opinion on this.

Thanks!

I'm still not sure if this is doable through the REST endpoint. We've found cases where the SOAP endpoint offers functionality that the REST endpoint does not, and this might be one those cases.

What I did was to use the SOAP endpoint instead. There was no built in method for this, so I had to use the general one. That, in this case, was an organization request, where I had se the request name to "AddMemberList".

You can create function like this:

function changeTemplate($state, template) { return { scope: { 'resource': '=', 'template': '=' }, template: '<div ng-include="{{template}}"></div>', link: function (scope) {.... // cool code } } }

And just change template argument on parent scope.

I feel like it has something to do with the array I'm trying to fill with sf::Vector2i... /me stares blankly at screen

So very simply put. netRead gets info from another function that is very basic. Then the switch goes through the net_step int...

After the game has received all the packets needed to continue, we trigger the nextGameUpdate() and send it 3 arrays and a dataSize int variable.

Thanks in advance if you figure this one out. ^^

Is MyKey actually immutable?

If a key is changed after it has been used in the Multimap (or a HashMap, for that matters), and the change effects hashCode() and equals(), you won't be able to find the associated values anymore: the modified hashcode means the lookup does not happen in the bucket where the values were stored.

15192511 0 Why is ngResource modifying saved object to this: g {0: "O", 1: "K", ..} after receiving a response

I have a default ngResource defined like this:

var Posts = $resource('/posts/');

And after I get one blogpost from my nodejs server like this:

$scope.post = Posts.get({_id:query._id});

User makes some changes to it, then I call:

$scope.post.$save();

After server returns response code 200, my $scope.post looks like this:

g {0: "O", 1: "K", $get: function, $save: function, $query: function, $remove: function, $delete: function}

Why? Is there some reason? Should letters "O" and "K" mean that the operation was a success and returned response 200? Would I be able to modify this behaviour without writing my own save method from scratch?

You can use regular expressions to match any of the bad words:

is_bad = re.search('|'.join(bad_words), bad_string) != None

I am having trouble grasping the concept of rand() and srand() in c++. I need to create a program that displays two random numbers, have the user enter a response, then match the response with a message and do this for 5 times.

My question is how do I use it, the instructions say I can't use the time() function and that seems to be in every tutorial online about rand().

this is what I have so far.

#include <iostream> #include <cmath> #include <cstdlib> using namespace std; int main() { int seed; int response; srand(1969); seed=(rand()%10+1); cout<<seed<<" * "<<seed<<" = "; cin>>response; cout<<response; if(response==seed*seed) cout<<"Correct!. you have correctly answered 1 out of 1."<<endl; else cout<<"Wrong!. You have correctly answered 0 out of 1."<<endl;

This just outputs something like 6*6 or 7*7, I thought the seed variable would be not necessary different but not the same all the time?

This is what the output should look like:

3 * 5 = 34 Wrongo. You have correctly answered 0 out of 1. 8 * 1 = 23 Wrongo. You have correctly answered 0 out of 2. 7 * 1 = 7 Correct! You have correctly answered 1 out of 3. 2 * 0 = 2 Wrongo. You have correctly answered 1 out of 4. 8 * 1 = 8 Correct! You have correctly answered 2 out of 5. Final Results: You have correctly answered 2 out of 5 for a 40% average.

and these are the requirements:

Your program should use rand() to generate pseudo-random numbers as needed. You may use srand() to initialize the random number generator, but please do not use any 'automatic' initializer (such as the time() function), as those are likely to be platform dependent. Your program should not use any loops.

Java's outputstream can not do what you want either, all it can do is send byte[] which is exactly what C#'s socket classes do.

If you want to send complex objects you must use some form of "Serializer" which will let you transform your objects in to a byte[] to be sent out.

A easy to use serializer that is built in to .NET is XmlSeralizer, this will produce a string that you can then feed in to a StreamWriter which will convert the string to a byte[] and write it out on to the socket. The other end would just use the reverse process using a StreamReader.

If you do not want to use that intermediate text step I would NOT recomend using BinaryFormatter like you see frequently on the internet, it is very "fragil" and having different levels of .NET Windows updates installed on both ends can end up breaking it. Instead I recommend using a 3rd party binary serializer like Protobuf-net

33597483 0 WPF MVVM ScrollIntoView

I have a view with two listboxes:

Listbox 1 elements: A, B, C. Listbox 2 elements: ..., A, ..., B, ..., C, ... (long list).

When the user selects an element in listbox 1, I want to scroll the same element into view (not select) also in listbox 2.

In my viewmodel I have a property bound to the SelectedItem of Listbox 2. But how can I scroll that element into view of listbox 2? Of course I cannot do listbox.ScrollIntoView(selectedItem) in my VM.

What's the best solution to solve this problem with the MVVM pattern?

This is definitely a nasty memory leak. I've opened an issue for it since no one else seems to have reported it.

Thanks for the "ugly workaround" emmby, that was helpful. A safer approach, although potentially with a performance impact, is to disable URLConnection caching altogether. Since the URLConnection.defaultUseCaches flag is static and, as you might guess, is the default for each instance's useCaches flag, you can just set this to false and no more instances will cache their connections. This will affect all implementations of URLConnection, so it may have farther-ranging effects than desired, but I think it's a reasonable trade-off.

You can just create a simple class like this and instantiate it very early in your app's onCreate():

public class URLConnectionNoCache extends URLConnection { protected URLConnectionNoCache(URL url) { super(url); setDefaultUseCaches(false); } public void connect() throws IOException { } }

The interesting thing is that since this occurs after your app is loaded and run, the system libs should already be cached, and this will only prevent further caching, so this probably gives the best possible trade-off: not caching your apk while allowing the performance benefits of caching the system jars.

Before doing this I did modify emmby's solution a bit to make it a standalone class that creates a background thread to periodically clear the cache. And I restricted it to just clear the app's apk, though that can be relaxed if desired. The thing to worry about here is that you're modifying the objects while they may be in use, which is generally not a good thing. If you do want to go this route you just need to call the start() method with a context, e.g. in your app's onCreate().

package com.example; import java.lang.reflect.Field; import java.net.URL; import java.util.HashMap; import java.util.Iterator; import java.util.Map; import java.util.jar.JarFile; import java.util.regex.Pattern; import android.content.Context; // hack to remove memory leak in JarURLConnectionImpl // from http://stackoverflow.com/questions/14610350/android-memory-leak-in-apache-harmonys-jarurlconnectionimpl public class JarURLMonitor { private static JarURLMonitor instance; private Pattern pat; private Field jarCacheField; public volatile boolean stop; private static final long CHECK_INTERVAL = 60 * 1000; public static synchronized void start(Context context) { if (instance == null) { instance = new JarURLMonitor(context); } } public static synchronized void stop() { if (instance != null) { instance.stop = true; } } private JarURLMonitor(Context context) { // get jar cache field try { final Class<?> cls = Class.forName("libcore.net.url.JarURLConnectionImpl"); jarCacheField = cls.getDeclaredField("jarCache"); jarCacheField.setAccessible(true); } catch (Exception e) { // log } if (jarCacheField != null) { // create pattern that matches our package: e.g. /data/app/<pkgname>-1.apk pat = Pattern.compile("^.*/" + context.getPackageName() + "-.*\\.apk$"); // start background thread to check it new Thread("JarURLMonitor") { @Override public void run() { try { while (!stop) { checkJarCache(); Thread.sleep(CHECK_INTERVAL); } } catch (Exception e) { // log } } }.start(); } } private void checkJarCache() throws Exception { @SuppressWarnings("unchecked") final HashMap<URL, JarFile> jarCache = (HashMap<URL, JarFile>)jarCacheField.get(null); final Iterator<Map.Entry<URL, JarFile>> iterator = jarCache.entrySet().iterator(); while (iterator.hasNext()) { final Map.Entry<URL, JarFile> entry = iterator.next(); final JarFile jarFile = entry.getValue(); final String file = jarFile.getName(); if (pat.matcher(file).matches()) { try { jarFile.close(); iterator.remove(); } catch (Exception e) { // log } } } } }

33876298 0 Script to be executed in a Div loaded by Ajax

I'm using AJAX to load an HTML page inside a div, but this page has scripts that don't work if I load the AJAX code using the click function. The problem is that I need the page to execute the scripts when I click some specific button.

The code that works, but load with main page, not when I click the button:

$('document').ready(function(){ $.ajax({ url: "primeiro/index.html", }).done(function (data) { $("#curso").html(data); $('#curso').each(function (index, element) { eval(element.innerHTML); }); }); });

I change to this:

$('document').ready(function(){ $("#loginsb").click(function () { $.ajax({ url: "primeiro/index.html", }).done(function(data) { $("#curso").html(data); $('#curso').each(function(index, element) { eval(element.innerHTML); }); }); }); });

Then the page seems to be "paused", so, can't load the script.

How can I use the click (in #loginsb button) function to load the content inside my div?

Thanks!

28821333 0 SQL database relational: performance modeling one to many

I have got a doubt modeling a relational database. I wonder which option is best in design and performance.

First option:

 Project Project_task Task -------- ----------- ----- id id_project id id_task

Second option (my doubt):

 Project Task -------- ------ id id id_project (INDEX)

Note: One project can has got many task, but one task only can has got a project.

Maybe the second option is less "relational" but I think it has more performance. I can get all the task of one project quering with a single SELECT without JOIN. I have got a table less than maintaining...

Is the second option a good practice and choice?

Does your TableAdapter refresh your DataSet? If it does, then you probably have something like a key getting initialized (remember, GUID==good, Int==bad). It's just like when you fill from a TableAdapter you need to call AcceptChanges to reset the state of all of the rows to unchanged.

33103263 0 Android MediaPlayer with LocalSocket not working

I am trying to play media from LocalSocket using MediaPlayer. The stream is of type MPEG-TS, which is availale in a LocalSocket input stream

Following code tries to setDataSource to the FileDescriptor of LocalSocket, but failes.

LocalSocket wsIns = fileThread.getReadSocket(); p = new MediaPlayer(); p.setDisplay(holder); FileDescriptor fd = wsIns.getFileDescriptor(); Log.e("TS","is valid ? "+fd.valid()); p.setDataSource(fd ,0, fileThread.getLength());

setDataSource fails with following exception.

10-13 17:21:31.510: W/System.err(6472): java.io.IOException: setDataSourceFD failed.: status=0x80000000 10-13 17:21:31.510: W/System.err(6472): at android.media.MediaPlayer.setDataSource(Native Method) 10-13 17:21:31.510: W/System.err(6472): at com.example.test.TSRenderActivity.surfaceCreated(TSRenderActivity.java:94)

The debug logs suggest that the error is primarily due to this, where fstat on the LocalSocket's file descriptor returns size of the file as 0.

But if I try wsIns.getInputStream().available() this api gives non zero number of bytes available.

Note : The same error on using p.setDataSource(fp);

I think that you need to use the order table instead of the order view to do this.

13340905 0

var re = /(#{5})/; console.log ("<foo>\n<bar>\n#####<foo>\n#####<bar>".match (re)); console.log ("<foo>\n<bar>\nfoo>\n<bar>".match (re));

output:

[ '#####', '#####', index: 12, input: '<foo>\n<bar>\n#####<foo>\n#####<bar>' ] null

If it's optional the regexp fails when there's no match and if it fails it returns null.

> /a/.exec("a") [ 'a', index: 0, input: 'a' ] > /a/.exec("b") null > "a".match(/a/) [ 'a', index: 0, input: 'a' ] > "b".match(/a/) null

Also, don't use String#match(), it's slower than RegExp#exec() and both return the same:

match() vs exec()

can any one tell me, what is the limit or how many it has to create while rekeying, otherwise why this many sad entires are being created.

message.getBytes() in your case is trying to convert Chinese Unicode characters to bytes using the default character set on your computer. If its a western charset, its going to be wrong.

Notice that String.getBytes() has another form with String.getBytes(String) where the string is the name of a character encoding that is used to convert the chars of the string to bytes.

The char type will hold Unicode. The byte type only holds raw bits in groups of 8.

So, to convert a Unicode string to bytes encoded as UTF-16 you would use this code:

String message =" 汉语"; byte[] utf16Bytes = message.getBytes("utf-16");

Substitute the name of any encoding that you want to use.

Similarly new String(String, byte[]) constructor can take an array of bytes encoded in some fashion and, given the String, can convert those bytes to Unicode characters.

For example: If you want to convert those bytes, which were encoded as utf-16 above, back to a String (which has Unicode chars in it):

String newMessage = new String(utf16Bytes, "utf-16");

Since I don't know what you mean by "binary code" above, I can't go much farther. As I see it, the Unicode chars have a binary code inside them that represents the characters one-by-one. Also the byte array has a binary code in it that represents the characters with a many-bytes-to-one-character representation. If you want to encrypt the byte array somehow, use a standard, proven encryption method and proven, time-tested procedures to secure the contents.

Try this to force correct detection of the charset:

Assuming you want to add the result z from each method:

static int number1(){ int x, y, z; x=2; y=2; z=x+y; return z; } static int number2(){ int x, y, z; x=3; y=2; z=x+y; return z; }

You could simplify this though to a more generic method:

static int adder(int a, int b) { return a + b; } public static void main (String [] args){ p = adder(2, 2) + adder(3, 2); }

You are creating an array that is too small for the loop. Namely: new char[28][31]; will only allow for a maximum index of 27 and 30. Your for loops are:

for (int i=0; i<=31; i++) for (int y=0; y<=28; y++)

Use i<31 and y<28, or increase your array to be [29][32]. Either one of these should solve your current problem.

13285184 0 In Scala, what's the most idiomatic way to name the case class equivalent of an ORM class?

I have to work with Lift's Mapper (I know there might be better ORMs for Scala, but this is not something I have the power to change right now). Typically, with Mapper, a table is defined this way:

package com.sample.model import net.liftweb.mapper._ class Table extends LongKeyedMapper[Table] with IdPK { def getSingleton = Table object other_table_id extends MappedLongForeignKey(this, OtherTable) object date_field extends MappedDate(this) object string_field extends MappedString(this, 255) def toCaseClass = ... } object Table extends Table with LongKeyedMetaMapper[Table]

Now I'd like to define a case class for Table to manipulate the records more easily, as Mapper is not very "Scala-idiomatic", not very type-safe, and definitely not immutable. My case class would look like this:

case class TableCC(id: Long, otherTableId: Long, dateField: Option[Date], ...) { def toMapper = ... }

How should I name the case class and where should I put it?

In com.sample.model with a different name (TableCC or TableCaseClass)?
In a different packagge (e.g. com.sample.model.caseclass) with the same name (Table)?
In the Table object?
...?

//Debug when ButtonClick1 is running connect_thread = array( [0] = System.Threading.Thread [1] = System.Threading.Thread [2] = System.Threading.Thread [3] = System.Threading.Thread ) //Debug when ButtonClick2 is running connect_thread = Error: Index was outside the bounds of the array.

Now, I want to add a new thread item into this thread array, but the indeces must continue like the old thread items (i.e, the next indeces will be [4], [5], [6], etc.)

I'm not worrying about this error:

//Debug when ButtonClick2 is running connect_thread = Error: Index was outside the bounds of the array.

because I can create a list of threads using dataGridView1.Rows.Count, and it will work fine. However, I'm looking to do it the other way other because when the user adds more data into dataGridView, the index will be wrong again.

How can I append new threads to the end of my thread array while preserving indeces?

If they are for use in template files you can have a look at extract. PHP Manual extract. It will extract all variables from an array into local variables.

XML loves recursion. It's a lot of work to lay out the nodes one-by-one or into some gigantic table grid -- your data format is heirarchical and your processing method should be as well.

Yep. Tried it. I'm just having trouble getting my mind around the best way to do it. I could use tables. I could use css. Absolute positioning. But nothing I come up with in HTML is really working for me.

XSLT is pretty good at transforming xml into html. the following xslt transforms your xml into a series of nested divs and tables. I'm using a table to get each colleague group aligned. seemed like the easiest way.

<xsl:template match="employee"> <div class="wrapper"> <div class="smallline" /> <div class="box"> <xsl:value-of select="name"/> <br/> <xsl:value-of select="title"/> </div> <xsl:if test="directReports/employee"> <div class="smallline"> </div> <table> <tr> <xsl:for-each select="directReports/employee"> <td> <xsl:apply-templates select="." /> </td> </xsl:for-each> </tr> </table> </xsl:if> </div> </xsl:template>

To preview, save the xslt from http://pastebin.com/f6597d519

Add <?xml-stylesheet href="foo.xslt" type="text/xsl"?> to the top of your employees xml, and open in a browser. In practice, you may want to transform on the server to avoid compatibility issues. To do that in C#, see How to apply an XSLT Stylesheet in C#

34166812 0 Hibernate/JPA: only one entry can have specific field value

I need something that seems not so specific but anyway I was unable to come up with nice and sophisticated solution.

Say I have very simple hibernate/jpa entity:

@Entity(name="entity") public class Type { @Id @GeneratedValue(strategy=GenerationType.AUTO) private Long id; @Column(unique = true, nullable = false) private String name; @Column(unique = false, nullable = false) private boolean defaultType; }

What i need is to somehow annotate defaultType field so only (and exactly) one persisted entity have this value as true. When new entity get persisted with this defaultType as true, the old one (with defaultType=true) entity has to be altered and its defaultType value changed to false. Also if any entity get changed (its defaultType got changed to true), same rule should apply.

As far I know this can be achieved inside business logic (e.g. in DAO layer), with DB trigger or with hibernates interceptor or event (If there is another way, please let me know). I tried with DAO solution but it's kind of bad solution because it can be bypassed and it is really clumsy for such simple operation. DB triggers can not be added with hibernate/jpa annotations (if I am not mistaken) and i am not sure how to make this functionality with hibernate interceptors/events.

So, what is best solution for this problem?

ARM support both big and little endian. This will most probably be set by the OS so it might be worth while checking this out beforehand.

There is also the issue of padding to word size in a struct:

struct st { char a; int b; };

will have a sizeof 8 and not the expected 5 bytes. This is so that the int will be word aligned. Generally align everything to 4 bytes and probably use the gcc packed attribute (struct my_packed_struct __attribute__ ((__packed__)) ) as well. This will ensure that the internals of the struct are as you expect.

Alternatively use the Android Simulator to generate the data file for you.

38652756 0 R: Removing unwanted `Variables sorted by number of missings:` from Graph

I am using the VIM package in R to plot missing values. I want to sort by number of values in the chart but dont want to see the section Variables sorted by number of missings:. The parameter sortVars=TRUE, is responsible for both the output and the sorting. Its useful for exploratory analysis but i want to use the output in a document using rmarkdown

Does anyone know how to implement this. It would be better explained with the code below

set.seed(300) Q <- c(1,2,3,4,5,6,NA) mydf <- data.frame(participent = (1:100), A1 = sample(Q,100,replace=TRUE), A2 = sample(Q,100,replace=TRUE), A3 = sample(Q,100,replace=TRUE), B1 = sample(Q,100,replace=TRUE), B2 = sample(Q,100,replace=TRUE), B3 = sample(Q,100,replace=TRUE), C1 = sample(Q,100,replace=TRUE), C2 = sample(Q,100,replace=TRUE), C3 = sample(Q,100,replace=TRUE) ) # Missing Values sorted by volume with unwanted output aggr_plot <- aggr(mydf, col=c('lightgrey','darkgreen'), numbers=FALSE, sortVars=TRUE, combined = TRUE, only.miss = TRUE, labels=names(mydf), cex.axis=.45, plot = TRUE) # Missing Values sorted by volume without unwanted output aggr_plot <- aggr(mydf, col=c('lightgrey','darkgreen'), numbers=FALSE, sortVars=FALSE, combined = TRUE, only.miss = TRUE, labels=names(mydf), cex.axis=.45, plot = TRUE)

Maybe you could do this:

tagFile.Save() if(tagFile.Tag.Title == infoVar1) { MessageBox.Show("Tags saved successfully"); }

After saving the tags into a file, you can validate with some attribute like Title, album, etc. :)

A simple question, which version(of taglib#) are you using?

You can do something like this:

 private void AddHourlyTask(string task) { DateTime expiration = DateTime.Now.AddHours(1); expiration = new DateTime(expiration.Year, expiration.Month, expiration.Day, expiration.Hour, expiration.Minute, expiration.Second, expiration.Kind); OnCacheRemove = new CacheItemRemovedCallback(CacheItemRemoved); HttpRuntime.Cache.Insert( task, task, null, expiration, Cache.NoSlidingExpiration, CacheItemPriority.NotRemovable, OnCacheRemove); }

And then in a separate function:

 public void CacheItemRemoved(string k, object v, CacheItemRemovedReason r) { if (k == "HelloWorld") { Console.Write("Hello, World!"); AddHourlyTask(k); }

This would go into your Application_Start() function as:

AddHourlyTask("HelloWorld");

In order for this to work, you also need to add this somewhere in your class:

private static CacheItemRemovedCallback OnCacheRemove = null;

The functions would all sit in your Global.asax.cs file

Like Felice (+1) said mocking creates a proxy which means you need to either make things virtual (so Moq can work its proxying magic and override the property).

As an alternative if you just want to squirt in a value you can manually stub the class you want to test and expose a means to get at the setter:-

public class FooStub : Foo { public SetBar(string newValue) { Bar = newValue; } }

Try to declare tabhost as static and call in child activity as below..

Instead private TabHost tabHost;

try static TabHost tabHost;

And in your Child Activity

 AccidentTabActivity.tabHost.setCurrentTab(2);

Then you can set your current tab as you want.

19008330 0 How can I best display this nested collection? (Can you tell me why my code isn't working?)

Can you tell me why this code isn't working?

I have a viewmodel with an observablecollection of searchresults which has an observablecollection of resultproperties. I cannot seem to display the nested collection of result properties like I want.

Here are the objects (abstracted for readability):

class ViewModel { public ObservableCollection<SearchResults<TDomain>> SearchResults { get; set; } } class SearchResults<TDomain> { public TDomain Result { get; set; } public ObservableCollection<ResultProperty> ResultProperties { get; set; } } class ResultProperty { public string PropertyValue { get; set; } }

Here is the xaml I cannot get to work. The DataContext is set to the ViewModel:

<StackPanel> <ItemsControl ItemsSource={Binding SearchResults}> <ItemsControl.ItemTemplate> <DataTemplate> <StackPanel> <TextBlock Text={Binding Result.Id}/> <StackPanel Orientation="Horizontal"> <ItemsControl ItemsSource={Binding ResultProperties}> <ItemsControl.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding PropertyValue}" /> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> </StackPanel> </StackPanel> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> <TextBlock Text="PLACEHOLDER /////"/> </StackPanel>

The outcome I am looking for is something like this:

[Stack panel to keep things orderly] 1 property1property2property3... 2 property1property2property3... 3 property1property2property3... PLACEHOLDER /////

The results I am getting are these

[Stack panel to keep things orderly] 1 2 3 PLACEHOLDER /////

In otherwords, the binding isn't picking up the string. I have verified that the collections are populating like expected. But I can't get the xaml to work.

**ADDITION INFORMATION

Ok, so I tried some of the solutions, but they aren't working so I am going to add more details because maybe I am missing something about how the collections are getting updated.

The viewmodel has a button on it called "Search" which uses an ICommand that calls a the view model's TrySearch method which is below:

public void TrySearch() { var results = _model.GetAll(); foreach(var result in results) this.SearchResults.Add(new SearchResults<TDomain>(result)); }

Could there be a reason this doesn't work because of the way the collection is updated? SearchResults is a dependency property (I know I know, it should be INPC, but its not, its dependency), but the other collections are not. Could this be a problem?

You say that the ? is supposed to be for a table name, so you need to provide an actual table name before calling Statement.executeUpdate(). At that point the JDBC driver will tell the database to actually run the statement, so obviously all parameters need to be bound.

Maybe you meant to write this:

CallableStatement call = jdbcConnection.prepareCall("call sp_msforeachtable(?)"); call.setString(1, "AnActualTableName"); call.executeUpdate();

or maybe you meant to write this:

CallableStatement call = jdbcConnection.prepareCall("call sp_msforeachtable(\"ALTER TABLE ? NOCHECK CONSTRAINT all\")"); call.setString(1, "AnActualTableName"); call.executeUpdate();

I'm not sure exactly what sp_msforeachtable() is supposed to do, but I do know that you have to provide values for all parameters before calling executeUpdate()

Add your forked Sylius repository like this in your composer.json

"repositories": [ { "type": "git", "url": "https://github.com/ylastapis/Sylius.git" }],

You can either require your master branch or create a custom branch (to merge your code pending that Sylius team accepts your merge, mine is called master-poc)

In the require section, require YOUR branch, prefixed by "dev-". so master became dev-master, thus my branch master-poc is now dev-master-poc

"require": { "sylius/sylius": "dev-master-poc" },

I also got a branch alias, Can't remember if it's still usefull

That's one of the downsides of having API's that returns null. The Null Object pattern could have been used here to simplify the API, relieving the clients from dealing with null values.

".offset() returns an object containing the properties top and left"

Therfore, you can do something like:

var menuOffset = menu.offset() || { top: 0, left: 0 }, menuTop = menuOffset.top + 100; $('.other').css('top', menuTop + 'px');

I had a bit similar problem. Which was actually being raised due to the duplication of name attribute of the job listener; which should be unique.

jobWasExecuted() method of listener gets called after the execute method of the job has finished its work. Roughly the Call hierarchy is like this

Listener->jobToBeExecuted()
Job->execute()
Listener->jobWasExecuted()

26189656 0 How can I set an NSDate object to midnight?

I have an NSDate object and I want to set it to an arbitrary time (say, midnight) so that I can use the timeIntervalSince1970 function to retrieve data consistently without worrying about the time when the object is created.

I've tried using an NSCalendar and modifying its components by using some Objective-C methods, like this:

let date: NSDate = NSDate() let cal: NSCalendar = NSCalendar(calendarIdentifier: NSGregorianCalendar)! let components: NSDateComponents = cal.components(NSCalendarUnit./* a unit of time */CalendarUnit, fromDate: date) let newDate: NSDate = cal.dateFromComponents(components)

The problem with the above method is that you can only set one unit of time (/* a unit of time */), so you could only have one of the following be accurate:

Day
Month
Year
Hours
Minutes
Seconds

Is there a way to set hours, minutes, and seconds at the same time and retain the date (day/month/year)?

The std::getline function you're using saves an input to a string (see: http://www.cplusplus.com/reference/string/string/getline/). If the argument you pass to the function was a string, it would get the whole line from your file, which is "0 50 100" and put it in your string.

You could trying to save it to a string and then splitting it to three parts and converting to ints using atoi or std::stoi in C++11 (check Convert string to int C++) - this way it would be easier to handle possible errors.

But there's an easier way to do it - assuming your numbers are split by spaces and pretty much everything is correct with them, the ">>" operator breaks on spaces. Try:

inFile >> inVal1; inFile >> inVal2; inFile >> inVal3;

Also, using cin.ignore() is not necessary when using the inFile buffer. Every stream has a different buffer associated with it (and cin != inFile) so you don't need to clear the cin buffer to read from your file.

32019322 0 HOWTO create GoogleCredential by using Service Account JSON

I am using the Java SDK for Android Publisher v2 and Oauth2 v2. Once I created the service account I was provided with a JSON of Google Play Android Developer service account with client id, email, private key etc. I have tried to look around and figure out how to create a Credential so that I use the AndoirdPublisher service to fetch info on my Android App's users subscriptions, entitlements etc and store this info on our backend servers.

I am getting hard time trying to figure out how to go about this. None of the documentations I have seen so far help in creating GoogleCredential using the downloaded JSON.

For example there is this documentation but it mentions only about P12 file and not the JSON. I want to avoid P12 if possible since I have multiple clients & I would like to save this JSON in some sort of database & then use it to create credential for each client.

Just to clarify I am trying to create the GoogleCredential object as described here,

import com.google.api.client.googleapis.auth.oauth2.GoogleCredential; import com.google.api.client.googleapis.javanet.GoogleNetHttpTransport; import com.google.api.client.http.HttpTransport; import com.google.api.client.json.JsonFactory; import com.google.api.client.json.jackson2.JacksonFactory; import com.google.api.services.sqladmin.SQLAdminScopes; // ... String emailAddress = "123456789000-abc123def456@developer.gserviceaccount.com"; JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance(); HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport(); GoogleCredential credential = new GoogleCredential.Builder() .setTransport(httpTransport) .setJsonFactory(JSON_FACTORY) .setServiceAccountId(emailAddress) .setServiceAccountPrivateKeyFromP12File(new File("MyProject.p12")) .setServiceAccountScopes(Collections.singleton(SQLAdminScopes.SQLSERVICE_ADMIN)) .build();

But instead of setting the Service Account using P12 File like so setServiceAccountPrivateKeyFromP12File(), I want to use the JSON that carries the same info & generated when I created the service account.

But stripchart does not work for 700 dots.

28436502 0 Global data from eloquent in Laravel to be used for layout

I am using some variables in the layout which will load data from the eloquent. For this purpose I am using repository pattern which are injected into the controller through constructor. But obviously, I don't want to repeat this logic in every controller I make.

What is the best approach to solve this?

I have tried injecting the repositories into the BaseController constructor, but the baseController constructor is not getting called automatically. I need to call for parent::__construct() first which requires repositories parameters to be passed. Which I believe is not the correct way to do this.

This is my BaseController.

 class BaseController extends Controller { /** * Setup the layout used by the controller. * * @return void */ protected $repo; public function __construct(Repository $repo) { $this->repo = $repo; } protected function setupLayout() { if ( ! is_null($this->layout)) { $this->layout = View::make($this->layout); } $data = $this->repo->someMethod(); View::share('global_data',$data); } }

BaseController constructor is not called automatically to resolve the dependencies.

What is the best approach to have global data from repositories to be used in the layout?

As specified on MSDN,

A multidimensional array is serialized as a one-dimensional array, and you should use it as a flat array.

As specified by Phil.Wheeler, this code does what you want:

List<int[]> name = new List<int[]>(){ new int[]{ 23, 21, 10 }, new int[]{ 45, 43, 50 }, new int[]{ 23, 21, 90 } }; string ser = (new System.Web.Script.Serialization.JavaScriptSerializer()).Serialize(name);

Hope it will help

what command are you using to insert below?

If you use the standard "o" keystroke while in Navigation mode, it should insert a new line immediately below whatever the cursor is on, and automatically place you into Insert mode, without inserting an extra "

Similarly an uppercase "O" will insert a new line above whatever line the cursor is on, and place you in insert mode.

what I am doing right now: forget about gtk.builder.connect_signals.

so after your code:

ui_builder = gtk.Builder() ui_builder.add_from_file('main.ui') self.win_main = builder.get_object('win_main')

I would have something similar to this:

list_of_handler_ids = [] import libxml2 doc = libxml2.parseFile('main.ui') ctxt = doc.xpathNewContext() signals = ctxt.xpathEval('//signal') for s in signals: handler = getattr(self, s.prop('handler')) signaller = getattr(self.win_main, s.parent.prop('id')) handler_id = signaller.connect(s.prop('name'), handler) list_of_handler_ids.append(handler_id)

which seems to sort of work after a first quick check.

Change your baseurl: "" in _config.yml to baseurl: "/".

The code in your head.html include is <link rel="stylesheet" href="{{ "css/main.css" | prepend: site.baseurl }}">

Jekyll renders this code as <link rel="stylesheet" href="css/main.css">. That code tries to find main.css relative to the page.

Add the / and the code rendered will be <link rel="stylesheet" href="/css/main.css">. This will try to find main.css relative to the site root.

We managed to find a solution so I'm going to respond to myself just in case someone else has the same problem and is looking for a fix.

We created a new page and started copying the code from the page across. We would publish the website after we added some code and tested that we could browse to the page, which we could. Eventually we had all the code in the new page and it was working fine. Problem solved!

Out of interest we renamed the new page to the old one and tried to access the page and we got the same error again. On changing the name back it worked fine.

TLDR version

Create a new page with a different name, copy your code across.
Try renaming the page.

The problem with:

BOOL r = [res isEqualToString:@"\x124Vx\xc3\xaa"];

is with the \x124 part. It seems you can only have hex values in the range 00 - ff. And note the removal of the [ ] around the string.

If you don't want the 4 to be considered part of the \x hex number, you can do this:

BOOL r = [res isEqualToString:@"\x12""4Vx\xc3\xaa"];

The two double-quote characters ensure the \x escape sequence stops where you need it to.

To eliminate the new warning about a possible missing comma when using such a string in an NSArray, you will need to use the older syntax to create the array:

NSArray *answers = [NSArray arrayWithObjects: @"", @"#", @"\x12""4Vx\xc3\xaa", nil ];

If you could make your IFoo<> interface covariant it would work, that is if you were allowed to change the declaration of it into:

public interface IFoo<out T>

(note the out). Because with covariance any IFoo<string> would also be an IFoo<object> because string is a reference type and derives from object.

But: A member of IFoo<>, the Handle method, uses the type parameter in a contravariant manner. So your interface cannot be declared covariant (out). (It could be declared contravariant (in) but that goes in the wrong direction for your example above.)

Read up on covariance and contravariance in generics.

The fundamental problem here is that your StringFoo handles only strings. Therefore it can never be used as an IFoo<object> because then you could pass for example a Giraffe instance (Giraffe derives from object, so a Giraffe is an object) into the StringFoo, and that is impossible when its Handle takes a string.

Trying to compare 2 tables in the same db. Table 1 is the main historical table, table 2 is the temporary table with new data rcvd from server and used to update table 1.

Need to output the items in table 1 that have a change in one of the fields on table 2.

i.e. table 1(Services)

 Service - folder- s2 - Real - s4 astatus - on - on - on - on

table 2(Services2)

 Service - folder - s2 - Real - s4 astatus - on - on - off - on

So I need the output to indicate that Real in astatus table 1 is off (again table 2 is just the reference temp table with new data to update table 1) I have all the updates and remaining code done. But i'm stuck on this comparison part...

my code is as follows:

cursor.execute("""Select inner.compare FROM (Select a.Real = aReal, b.Real = bReal FROM Services a JOIN Services2 b ON (lower(a.Service || a.Folder) = lower(b.Service || b.Folder)))inner.compare WHERE inner.astat != inner.bstat""") print inner.compare

7515672 0 Modal blocking dialog in Javascript

I'm developing Openlayers toolbar in Javascript with jQuery and jQuery UI.

One feature that I want to implement is Adding points to the map.

In openLayers you have to listen for event called 'sketchcomplete'.

layer.events.on({ 'sketchcomplete': onPointAdded });

The problem is in onPointAdded callback. This callback should return true or false. True mean that the point should be added to the map and false means cancel adding this point to the map.

Now the callback looks like this:

onPointAdded = function(feature) { var f = feature.feature; var result = false; $('#dialog-point-add').dialog({ modal : true, buttons : { 'Add point' : function() { result = true; $(this).dialog("close"); }, 'Cancel' : function() { result = false; $(this).dialog("close"); } } }); return result; };

The problem is that this dialog doesn't block the executing code. I'm asking You How to handle this situation? I want to show dialog to the user with confirmation for adding the point.

First - you should be able to just use File.ReadAllLines instead of reading the text and splitting....

You may need to trim the results. If there is extra whitespace on the lines, the condition may fail. Try using:

if (check[0].Trim() == "1") {

This will trim off any whitespace, which should cause your conditional to succeed.

You can also put a breakpoint in, and inspect the values in the debugger. This will help you better diagnose the issue.

#include <string> std::string overlap(std::string first, std::string const & second) { std::size_t pos = 0; for (std::size_t i = 1; i < first.size(); ++i) { if (first.compare(first.size() - i, i, second, 0, i) == 0) { pos = i; } } first.append(second, pos, second.npos); return first; }

Usage:

std::string result = overlap("abcde", "defgh");

And to overlap a whole range, use std::accumulate:

#include <algorithm> #include <iostream> #include <vector> int main() { std::vector<std::string> strings = {"abc", "def", "fegh", "ghq"}; std::cout << std::accumulate(strings.begin(), strings.end(), std::string(), overlap) << std::endl; }

It's because you set the display:block for your a, so the border will be around the box (which has height set to 46px). Looks like you explicitly set padding-bottom to 0 and then it still should work (the bottom border should be close to the link text?) but not really, because you also set the line-height to be equal to the height (both are 46px), so the text is centered vertically and give a space between the baseline and the border-bottom.

To solve this problem, simply remove the line display: block; in your css for the a tag. You don't need that at all, removing will solve your problem:

#menu ul li a { text-decoration:none; color:#ccc; margin-right:5px; height:46px; line-height:46px; padding:0 5px 0 5px; font-size:20px; }

So far by looking at the source of of pysqlite, I can say that it is not possible to share connection or cursor objects (see pysqlite_check_thread function usage) only.

pysqlite_check_thread function raises ProgrammingError exception with that message

SQLite objects created in a thread can only be used in that same thread.

Some function in your source code catches that exception and prints it.

In order to find places in your source code that call connection methods in other threads, I would suggest to write call wrapper over connection object something like this:

# script name: sqllitethread.py import inspect import sqlite3 import threading import thread from sqlite3 import ProgrammingError class CallWrapper(object): def __init__(self, obj): self.obj = obj self.main_thread_id = thread.get_ident() def __getattr__(self, name): if self.main_thread_id != thread.get_ident(): print "Thread %s requested `%s` attribute from %s" % (thread.get_ident(), name, self.obj) for frame in inspect.getouterframes(inspect.currentframe())[1:]: if frame[1].endswith('threading.py'): continue print "\t", "%s:%s" % (frame[1], frame[2]), frame[3], frame[4][0].strip() return getattr(self.obj, name) conn = CallWrapper(sqlite3.connect('example.db')) c = conn.cursor() def worker(): try: conn.execute('.tables') except ProgrammingError, e: print e t = threading.Thread(target=worker) t.start() t.join()

Output example:

Thread 140390877370112 requested `execute` attribute from <sqlite3.Connection object at 0x7faf4e659858> sqllitethread.py:30 worker conn.execute('.tables') SQLite objects created in a thread can only be used in that same thread.The object was created in thread id 140390912665408 and this is thread id 140390877370112

For simple enumeration, simply using fast enumeration (i.e. a for…in… loop) is the more idiomatic option. The block method might be marginally faster, but that doesn't matter much in most cases — few programs are CPU-bound, and even then it's rare that the loop itself rather than the computation inside will be a bottleneck.

A simple loop also reads more clearly. Here's the boilerplate of the two versions:

for (id x in y){ } [y enumerateObjectsUsingBlock:^(id x, NSUInteger index, BOOL *stop){ }];

Even if you add a variable to track the index, the simple loop is easier to read.

So when you should use enumerateObjectsUsingBlock:? When you're storing a block to execute later or in multiple places. It's good for when you're actually using a block as a first-class function rather than an overwrought replacement for a loop body.

hei, need some help to convert this linq query to dot notation:

 var productions = from row in data group row by row.PRODUCTION_NAME into gr select new { Group = gr.Key, Jobs = from row in gr orderby row.SortFieldCard group row by row.JOB_NAME into job select new { job.Key, Cards = job } };

11745880 0 Accessing objects parent property in django profiles

I am using django profiles with having different types of profiles.

My Profile Model of Company is similar to:

from django.db import models from django.contrib.auth.models import User from accounts.models import UserProfile from jobs.models import City from proj import settings from django.core.mail import send_mail class Company(UserProfile): name=models.CharField(max_length=50) short_description=models.CharField(max_length=255) tags=models.CharField(max_length=50) profile_url=models.URLField() company_established=models.DateField(null=True,blank=True) contact_person=models.CharField(max_length=100) phone=models.CharField(max_length=50) address=models.CharField(max_length=200) city=models.ForeignKey(City,default=True) def send_activation_email(self): self.set_activation_key(self.username) email_subject = 'Your '+settings.SITE_NAME+' account confirmation' email_body = """Hello, %s, and thanks for signing up for an example.com account!\n\nTo activate your account, click this link within 48 hours:\n\nhttp://"""+settings.SITE_URL+"/accounts/activate/%s""" % (self.username,self.activation_key) send_mail(email_subject, email_body, 'acccounts@site.com', [self.email])

Here I am inheriting Company from UserProfile and in send activation email, I am trying to use properties and methods of parent classes user and userprofile. Its direct parent is userprofile while user has onetoone relation with userprofile. So I tried to call self.activation_key that is defined in userpofile and called self.username that is property of user class/table and getting error on self.username .

So seems like I am calling self.username in wrong way,so how can I access self.username ? Any detail will be helpful and appreciated.

You are right, there's a limit (and a lot of work arounds techniques) in every processor architecture, but you will run into a lot of messy problems before you run out of numbers. Performance issues related to great amounts of data is a problem that you are likely to have.
