  • Free Application Lifecycle Management Tools for .NET Development

    - by pablocastilla
    I would like to achieve the following: I want a free Application Lifecycle Management (ALM) environment surrounding vs2008 sp1. (My company is short of cash). I want all the stuff: CI, BugTracking, task panel, Wiki, Source control... all integrating themselves. If I could have some kind of scrum managing tools it would be better. Any recommendation? Thanks in advance.

  • Perl - socket programming

    - by Octopus
    I have just started learning socket programming using perl. I am wondering if there is any method to send the output (STDOUT) data/images from already running scripts/tools using perl socket programming. If anyone could explain or provide reference for the same. Any suggestions to write perl programs to automate this task.

  • Should all public methods of an API be documented?

    - by cynicalman
    When writing "library" type classes, is it better practice to always write markup documentation (i.e. javadoc) in java or assume that the code can be "self-documenting"? For example, given the following method stub: /** * Copies all readable bytes from the provided input stream to the provided output * stream. The output stream will be flushed, but neither stream will be closed. * * @param inStream an InputStream from which to read bytes. * @param outStream an OutputStream to which to copy the read bytes. * @throws IOException if there are any errors reading or writing. */ public void copyStream(InputStream inStream, OutputStream outStream) throws IOException { // copy the stream } The javadoc seems to be self-evident, and noise that just needs to be updated if the funcion is changed at all. But the sentence about flushing and not closing the stream could be valuable. So, when writing a library, is it best to: a) always document b) document anything that isn't obvious c) never document (code should speak for itself!) I usually use b), myself (since the code can be self-documenting otherwise)...

  • running a python script where dependencies are not avail: distributed computing

    - by sadhu_
    Hi, I have access to a grid (running condor) that would (potentially) allow to very substantially reduce how long by nltk based nlp tasks take. unfortunately, i dont have root access on the cluster so cannot install new packages, only run whatever is available on the linux boxes. python is of course available, but nltk isnt - i was wondering however, if there might be a way around this somehow ? is there a way i can somehow still distribute the task in a self-contained 'package' of some sort? Thanks for your hel

  • py2app, pyObjc & macports compilation errors

    - by Neewok
    Hi, I'm currently writing a small python app that embeds cherrypy and django using py2app. It worked well until I tried to include pyobjc in my project, since my app needed a small GUI (which consists of a small icon in the top menu bar + a drop down menu). I can run my python script without any problem (I'm using python 2.6 with macports), but I can't launch the application bundle generated by py2app. A dialog box appears with the following message: ImportError: dlopen(/Users/denis/tlon/standalone/mac/dist/django_cherry.app/Contents/Resources/lib/python2.6/lib-dynload/CoreFoundation/_inlines.so, 2): no suitable image found. Did find: /Users/denis/tlon/standalone/mac/dist/django_cherry.app/Contents/Resources/lib/python2.6/lib-dynload/CoreFoundation/_inlines.so: mach-o, but wrong architecture I did a quick : sudo port -u install py26-pyobjc +universal but for some reason macports tries to build openssl, with which compilation fails each time. It seems the problem is related to zLib - this is what appears in the logs : :info:build ld: warning: in /opt/local/lib/libz.dylib, file is not of required architecture ...And here is the output of file /opt/local/lib/libz.dylib : /opt/local/lib/libz.dylib: Mach-O universal binary with 2 architectures /opt/local/lib/libz.dylib (for architecture x86_64): Mach-O 64-bit dynamically linked shared library x86_64 /opt/local/lib/libz.dylib (for architecture i386): Mach-O dynamically linked shared library i386 Nothing looks wrong to me. I'm a bit stuck here. I don't even understand what openssl has to do with pyObjc, but it looks like I can't go anywhere if I don't manage to compile it. Macports really suck sometimes :/ EDIT I manage to fix Macports issue, but not py2app one. If I get it right, py2app try to create a 32-bits app, while Core Foundation files on Snow Leopard are for 64 bits architectures. Damn. Either I build this on Leopard, either I have to find a way to create a 64bit app with py2app, but then Snow Leopard only.

  • Adobe Air Debugger not visible

    - by Chin
    Have a little conundrum, when I debug my air app. It goes through the build process and seemingly launches. I can see the process in windows task manager, but can not see the actual application. Kind of strange I know. If anyone has had the same problem and can offer a shortcut to success, I'd much appreciate a pointer. Thanks

  • Can I treat IronPython as a Pythonic replacement to C#?

    - by Ewan Nathaniel
    Hey guys! I do understand that this topic has been covered in some way at StackOverflow but I'm still not able to figure out the exact answer: can I treat IronPython as a Pythonic replacement to C#? I use CPython every day, I love the Zen :) but my current task is a Windows-only application with a complex GUI and some other features which I would like to implement using .NET.

  • Newbie question about Java

    - by Rob Nicholson
    Okay, I know that Java is a language but somebody has asked me if they can write a web application to interface in with a web app I've written in ASP.NET. I'm implementing a web service to serve up an XML so it's pretty language agnostic. However, I'm not 100% sure whether going down the Java route makes a lot of sense. I was kind of expecting PHP or ASP.NET server side code with maybe some Ajax/JavaScript or maybe a heavier client JavaScript program using JScript. Could some kind sole explain the basic Java environment when it comes with webapps. I've inferred the following - am I barking up the right tree? Java when run like ASP.NET is called JSP JavaBeans is a bit like the .NET framework, i.e. it's a library of re-usable components Java EE is a bit like ASP.NET in that it's a framework for building web pages on a server Java can also run on the client but it needs the Java VM installing When running Java on the client, can you use JavaBeans and is there a framework? Can it also use JScript? I don't think so as JScript is JavaScript library. Whilst running Java on the server would be okay, this is a relatively small application and therefore Java sounds like a bit of overkill. PHP or ASP.NET feels a better fit. But I don't think they should go down the Java applet in the browser and it adds complexity that's not needed. Thanks, Rob.

  • WPF Using commands to slow to update UI controls

    - by toni
    Hi, I bind a command to a button through command property and doing a command binding in the page it is placed. In execute method I create an instance of a class that contains the background worker and I start it (this is a long task). The background worker (bw) class contains a variable isRunning that it is set to true before DoWork method is executed and to false when RunWorkerCompleted is executed. So from the code behind of the page where button is placed, in CanExecute method I set e.canExecute to true if bw is no running (isRunning = false), and e.canExecute to false if isRunning = true. WHen I press the button, it launch bw process for a long time and the button gets disabled. Ok this is correct, but when background worker (bw) finishes, the button doesn't returns to enabled until I press it again. When it is disabled and I press (when bw is finished) it gets enabled. Why the button is not returning automatically to enabled at the end of the bw? my code snippet: <Page x:Class="GParts.Pages.MyPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Microsoft_Windows_Themes="clr-namespace:Microsoft.Windows.Themes; assembly=PresentationFramework.Aero" xmlns:local="clr-namespace:GParts" Loaded="Page_Loaded" Unloaded="Page_Unloaded" Height="Auto"> <Page.CommandBindings> <CommandBinding Command="{x:Static local:Pages.MyPage.rcmd}" Executed="CommandBinding_Executed" CanExecute="CommandBinding_CanExecute"/> </Page.CommandBindings> <...> <Button Command="{x:Static local:Pages.MyPage.rcmd}" /> <...> </Page> The code behind of the page: namespace GParts.Pages { public partial class MyPage : Page { public static RoutedCommand rcmd = new RoutedCommand(); private cBgWorker bw; <...> // ExecutedRoutedEventHandler for the custom button remove all command. private void CommandBinding_Executed(object sender, ExecutedRoutedEventArgs e) { // get an isntance of the background worker class bw = new cBgWorker(); // start the long task bw.StartTask(); } // CanExecuteRoutedEventHandler for the custom button remove all command. private void CommandBinding_CanExecute(object sender, CanExecuteRoutedEventArgs e) { // bw is the instance of background worker class if (bw == null) { e.CanExecute = true; } else { e.CanExecute = !bw.isRunning;// isRunning indicates if bw is //executing now } } <...> } // end class } // end namespace

  • How to exclude R*.class files from a proguard build

    - by Jeremy Bell
    I am one step away from making the method described here: http://stackoverflow.com/questions/2761443/targeting-android-with-scala-2-8-trunk-builds work with a single project (vs one project for scala and one for android). I've come across a problem. Using this input file (arguments to) proguard: -injars bin;lib/scala-library.jar(!META-INF/MANIFEST.MF,!library.properties) -outjar lib/scandroid.jar -libraryjars lib/android.jar -dontwarn -dontoptimize -dontobfuscate -dontskipnonpubliclibraryclasses -dontskipnonpubliclibraryclassmembers -keepattributes Exceptions,InnerClasses,Signature,Deprecated, SourceFile,LineNumberTable,*Annotation*,EnclosingMethod -keep public class org.scala.jeb.** { public protected *; } -keep public class org.xml.sax.EntityResolver { public protected *; } Proguard successfully builds scandroid.jar, however it appears to have included the generated R classes that the android resource builder generates and compiles. In this case, they are located in bin/org/jeb/R*.class. This is not what I want. The android dalvik converter cannot build because it thinks there is a duplicate of the R class (it's in scandroid and also the R*.class files). How can I modify the above proguard arguments to exclude the R*.class files from the scandroid.jar so the dalvik converter is happy? Edit: I should note that I tried adding ;bin/org/jeb/R.class;etc... to the -libraryjars argument, and that only seemed to cause it to complain about duplicate classes, and in addition proguard decided to exclude my scala class files too.

  • compile AMR-nb codec with RVCT for WinCE/Window Mobile

    - by pps
    Hello everybody, I'm working on amr speech codec (porting/optimization) I have an arm (for WinCE) optimized version from voiceage and I use it as a reference in performance testing. So far, binary produced with my lib beats the other one by around 20-30%! I use Vs2008 and I have limited access to ARM instruction set I can generate with Microsoft compiler. So I tried to look for alternative compiler to see what would be performance difference. I have RVCT compiler, but it produces elf binaries/object files. However, I run my test on a wince mobile phone (TyTn 2) so I need to find a way to run code compiled with RVCT on WinCE. Some of the options are 1) to produce assembly listing (-S option of armcc), and try to assemble with some other assembler that can create COFF (MS assembler for arm) 2) compile and convert generated ELF object file to COFF object (seems like objcopy of gnu binutils could help me with that) 3) using fromelf utility supplied by RVCT create BIN file and somehow try to mangle the bits so I can execute them ;) My first attempt is to create a simple c++ file with one exported function, compile it with RVCT and then try to run that function on the smartphone. The emitted assembly cannot be assembled by the ms assembler (not only they are not compatible, but also ms assembler rejects some of the instructions generated with RVCT compiler; ASR opcode in my case) Then I tried to convert ELF object to coff format and I can't find any information on that. There is a gcc port for ce and objcopy from that toolset is supposed to be able to do the task. However, I can't get it working. I tried different switches, but I have no idea what exactly I need to specify as bfdname for input and output format. So, I couldn't get it working either. Dumping with fromelf and using generated bin file seems to be overkill, so I decided to ask you guys if there is anything I should try to do or maybe someone has already done similar task and could help me. Basically, all I want to do is to compile my code with RVCT compiler and see what's the performance difference. My code has zero dependencies on any c runtime functions. thanks!

  • Best way to handle Integer overflow in C#?

    - by byte
    Handling integer overflow is a common task, but what's the best way to handle it in C#? Is there some syntactic sugar to make it simpler than with other languages? Or is this really the best way? int x = foo(); int test = x * common; if(test / common != x) Console.WriteLine("oh noes!"); else Console.WriteLine("safe!");

  • No Commons Logging in Android?

    - by Joe Boese
    Hello all, I have a pretty big library I developed specifically for use in my Android Application. However business logic itself has no dependency on Android. To preserve that, I used Commons Logging throughout this library and it's respective JUnit tests (which I run in Eclipse). However now that I am starting to integrate it into an Activity which I launch on Android, I am unable to get my logging to work. In Eclipse/JUnit, I had simply pulled in log4j's jar file as well as a log4j.properties file. This doesn't seem to work when deploying to a device. After struggling with attempting to get that to work for several hours, I gave up and tried replacing all my commons logging stuff with android.util.Log. Now I can log on the device.. but all JUnit tests are broken. When any JUnit tries to log using android.util.Log, it throws a RuntimeException 'Stub!'. I would prefer to revert to my commons logging approach.. if anyone can help with that.. otherwise.. what can I do to get my JUnit test cases running using 'android.util.Log'? Many thanks in advance.. I've spent more than a few hours on this and I'd like to move on to writing real code again! Joe

  • Currency Format in C# to shorten the output string

    - by james.ingham
    Hey, I currently have a Currency Format method: private string FormatCurrency(double moneyIn) { CultureInfo ci = new CultureInfo("en-GB"); return moneyIn.ToString("c", ci); } I'm looking to adapt this to shorten the string as the currency get's larger. Kind of like how stack overflow goes from 999 to 1k instead of 1000 (or 1.6k instead of 1555). I imagine that this is a relativly easy task however is there any built in function for it or would you just have to manually manipulate the string? Thanks

  • Will client side performance improve if images/scripts/styles on different subdomains?

    - by Andrey
    Hi, I have a domain specifically for static content, so cookies don't travel along with requests to images/scripts/css. Now, I think I've read somewhere that most browsers only open one download thread for each domain/subdomain, so different static content can't be downloaded in parallel if on the same domain. Will it make difference for browsers if i place scripts in script.mycdn.com, styles in css.mycdn.com and images in images.mycdn.com? Will it allow to let browser download images at the same time as scripts and styles? mycdn.com is of course a made up name :) Thanks! Andrey

  • How to investigate if opencl is possible for an algorithm

    - by Marnix
    I have a heavy-duty algorithm in C# that takes two large Bitmaps of about 10000x5000 and performs photo and ray collision operations on a 3D model to map photos on the 3D model. I would like to know if it is possible to convert such an algorithm to OpenCL to optimize parallel operations during the algorithm. But before asking you to go into the details of the algorithm, I would like to know how I can investigate if my algorithm is convertible to OpenCL. I am not experienced in OpenCL and I would like to know if it is worth it to get into it and learn how it works. Are there things I have to look for that will definitely not work on the graphics card? (for-loops, recursion) Update: My algorithm goes something like: foreach photo split the photo in 64x64 blocks foreach block cast a ray from the camera to the 3D model foreach triangle in 3D model perform raycheck
