  • Flex 4 - What makes a GC root?

    - by Michael Brewer-Davis
    What are the rules for something to be a GC root in Flash? I'm using the Flash Builder 4 profiler, and I'm finding odd things are labeled as GC roots in the object reference details (e.g., an Image control that is no longer in the display list, nor static).

  • Django "comment_was_flagged" signal

    - by tsoporan
    Hello, This is my first time working with django signals and I would like to hook the "comment_was_flagged" signal provided by the comments app to notify me when a comment is flagged. This is my code, but it doesn't seem to work, am I missing something? from django.contrib.comments.signals import comment_was_flagged from django.core.mail import send_mail def comment_flagged_notification(sender, **kwargs): send_mail('testing moderation', 'testing', 'test@localhost', ['[email protected]',]) comment_was_flagged.connect(comment_flagged_notification) (I am just testing the email for now, but I have assured the email is sending properly.) Thanks!

  • Using the Ocean Browsercaps files with .NET 4

    - by Craig
    I have been trying to use the Ocean browsercaps files from http://owenbrady.net/browsercaps/ in a ASP.NET 4 application. When I drop the files into the App_Browsers folder I get the error The browser or gateway element with ID 'docomon505i' cannot be found. Are these files compatible with .NET4 or am I doing something wrong. The documentation is sparse.

  • Eclipse PDT debugging web application: evaluating expressions in a console

    - by dreftymac
    When using Eclipse PDT with XDebug to debug a PHP web application, is there any way to open up a console window that will allow me to type in and see the value of arbitrary expressions in the current scope? This would seem like an obvious element of the debugging environment, and I may be missing something, but the only thing resembling a console says "no consoles to display at this time"

  • Is there a C# secure socket other than SSLStream?

    - by AI0867
    .NET 2.0 provides only the System.Net.Security.SslStream class for secure sockets in .NET 2.0 and higher, but this uses the Stream interface, which provides the blocking Read/Write members and asynchronous Begin{Read,Write} members. I'm looking for a class that provides functionality similar to System.Net.Sockets.Socket. Specifically, something resembling Poll/Select, so I can handle multiple sockets in a single thread without blocking. The mentalis security library supplies a SecureSocket class, but is explicitly unsupported for versions greater than .NET 1.1.

  • BlackBerry barcode scanning library?

    - by Mat Nadrofsky
    Anyone got a good handle on a barcode scanning library that can be used to read in UPC-A, EAN-13 or other major barcode formats based on input from the digital camera? Does RIM have a standard library already available for this? I know that BlackBerry Messenger has 2D barcode scanning built-in so I'm guessing there must be something available, though not sure if it's proprietary or not.

  • JsLint 'out of scope' error

    - by Rajat
    function test(){ if(true){ var a = 5; } alert(a); } test(); I keep getting 'out of scope' errors in my JS code when I check with JsLint which make no sense to me.So I quickly created an example. Is there something actually wrong with this code piece, as the variable is eventually hoisted to the top of the function anyways.

  • Eclipse doesn’t recognize style in the Android Layout builder?

    - by Artem Russakovskii
    Since Android supports styles and it's good practice to use them (similar to CSS), I made a new style and applied it to 3 buttons. The Layout builder in Eclipse did not register the changes and either broke (showed nothing) or didn't apply styles at all. After running the app in the emulator, styles are correctly applied. So is there something I'm missing or the Android plugin doesn't support styles?

  • Font Family Selection With Google Charts?

    - by mazniak
    Is it possible to set font-family for any of the non-flash Google chart visualizations? Specifically for things like the text on the chart axis. Google charts is powerful, but ugly. And unfortunately I can’t move to something nicer, like gRaphael.

  • Generate Ant build file

    - by inakiabt
    I have the following project structure: root/ comp/ env/ version/ build.xml build.xml build.xml Where root/comp/env/version/build.xml is: <project name="comp-env-version" basedir="."> <import file="../build.xml" optional="true" /> <echo>Comp Env Version tasks</echo> <target name="run"> <echo>Comp Env Version run task</echo> </target> </project> root/comp/env/build.xml is: <project name="comp-env" basedir="."> <import file="../build.xml" optional="true" /> <echo>Comp Env tasks</echo> <target name="run"> <echo>Comp Env run task</echo> </target> </project> root/comp/build.xml is: <project name="comp" basedir="."> <echo>Comp tasks</echo> </project> Each build file imports the parent build file and each child inherits and overrides parent tasks/properties. What I need is to get the generated build XML without run anything. For example, if I run "ant" (or something like that) on root/comp/env/version/, I would like to get the following output: <project name="comp-env-version" basedir="."> <echo>Comp tasks</echo> <echo>Comp Env tasks</echo> <echo>Comp Env Version tasks</echo> <target name="run"> <echo>Comp Env Version run task</echo> </target> </project> Is there an Ant plugin to do this? With Maven? What are my options if not? EDIT: I need something like "mvn help:effective-pom" for Ant.

  • Using logarithms to normalize a vector to avoid overflow

    - by muscicapa
    http://stackoverflow.com/questions/2293762/problem-with-arithmetic-using-logarithms-to-avoid-numerical-underflow-take-2 Having seen the above and having seen softmax normalization I was trying to normalize a vector while avoiding overflow - that is (x1 x2 x3 x4 ... xn) the normalized form for me has the sum of squares as 1.0 So what I thought of doing is s=(2*log(x1)+2*log(x2)+...+2*log(xn))/2 so the two factor can be taken off and finally the normalized vector is exp(log(x1)-s), , ..., exp(log(xn)-s) but I am evidently doing something wrong here, what?
