• Is there a Visual Studio style tool/IDE?

  - by Tim

  I have been developing in the windows space with Visual Studio for a while now with work, but I have also been using Ubuntu for a while and am keen to get into some software development for linux. I should also note. I am not looking for .NET and I am aware of mono. I am also familiar with c++ development and some python, so the language isn't so much relevant as the "all in one" aspect. I was interested to know if there is a useful all in one code/debug/design(gui) IDE similar to something like Visual Studio but for linux?

• How do I get the XAML comiler to use textual content property on custom classes?

  - by Duncan

  Given a simple C# class definition like: [System.Windows.Markup.ContentProperty("PropertyOne")] public class SimpleBase { public string PropertyOne { get; set; } public string PropertyTwo { get; set; } } why is it not possible to ommit the sys:string tags around the word Test in the xaml below. <custom:SimpleBase x:Class="TestType" xmlns:custom="clr-namespace:ConsoleApplication1;assembly=" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:sys="clr-namespace:System;assembly=mscorlib"> <sys:String>Test</sys:String> </custom:SimpleBase> Somehow the compiler correctly coverts text to string for the type String, why doesn't it work for my custom type? The context can be found on my blog: http://www.deconflations.com/?tag=xaml

• "Invalid signature": oAuth provider with Django-piston

  - by Martin Eve

  Hi, I'm working with django-piston to attempt to create an API that supports oAuth. I started out using the tutorial at: http://blog.carduner.net/2010/01/26/django-piston-and-oauth/ I added a consumer to piston's admin interface with key and secret both set to "abcd" for test purposes. The urls are successfully wired-up and the oAuth provider is called. However, running my get request token tests with tripit (python get_request_token.py "http://127.0.0.1:8000/api" abcd abcd), I receive the following error: Invalid signature. Expected signature base string: GET&http%3A%2F%2F127.0.0.1%3A8000%2Fapi%2Foauth%2Frequest_token%2F&oauth_consumer_key%3Dabcd%26oauth_nonce%3D0c0bdded5b1afb8eddf94f7ccc672658%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1275135410%26oauth_version%3D1.0 The problem seems to lie inside the _check_signature method of Piston's oauth.py, where valid_sig = signature_method.check_signature(oauth_request, consumer, token, signature) is returning false. I can't, however, work out how to get the signature validated. Any ideas? -----Update----- If I remove the test consumer from piston's backend, the response returned is correctly set to "Invalid consumer", so this lookup appears to be working.

• debugging with internet explorer

  - by baiano

  I have some code that I thought I had written so that it would play nice on IE. But apparently it does not. I use IE8 for my testing and get quite frustrated with the built-in debugging 'tool'. I found that firebug has a javascript tool that debugs for IE but I have to click it for every page, wait for it to load and then test my script. Is there a way to make IE ALWAYS load the firebug .js file? I tried searching for way to set up a custom header file for my IE installation but was unsuccessful. Is there another tool out there that would be better/easier to use? Another way to test scripts for IE compatibility?

• how to compile a program with gtkmozembed.h

  - by ganapati hegde

  Hi, i have written a program under ubuntu, in which i include gtkmozembed.h. I am facing a problem in compiling the program.Below is the simplest form of a program which uses gtkmozembed. #include <gtk/gtk.h> #include <stdio.h> #include <gtkmozembed.h> int main(){ GtkWidget *mozEmbed; mozEmbed = gtk_moz_embed_new(); return 0; } Eventhough, the above program is doing nothing, compiling that program is a lot for me... I am trying to comile the above program like below gcc `pkg-config --libs --cflags gtk+-2.0` test.c -o test and it is giving the following error... error: gtkmozembed.h: No such file or directory I can understand, something else has to be added to the above gcc line,so that the compiler can find the gtkmozembed.h, but not getting what is that, 'something'...Looking for someone's help..Thank you...

• `xcalib -i -a` controls only one of two screens - can it control both?

  - by drevicko

  I am using 2 screens, and wish to invert the colors on both of them without using compiz (I'm using gnome shell). I can use xcalib -invert -alter as suggested in this question, but it only inverts one of the screens. Is there a way to specify both of them, or even which of them, using xcalib? Is there another way? With xcalib, you can specify which screen to alter with the -d (-display) or -s (-screen) options, but alas, X seems to be aware of just one screen: when I use the w command I only see one (the usual ":0") ps: this question was originally posted by k0pernikus as a comment here.

• How to migrate from Banshee to Rhythmbox?

  - by rafalcieslak

  As it has been decided, Ubuntu Precise 12.04 will feature Rhythmbox as the default music player. I am aware, that it does not mean that I will not be able to use Banshee, nevertheless I would like to switch to it. I have been a Rhythmbox fan for a long time, but after the switch to Banshee in Natty I decided to give it a try and completely migrated to it. However, I am not very happy with it, it lags for me a lot and has some other issues. I would like to export all Banshee data to Rhythmbox. That includes: Music library Playlists Preferably playcounts and ratings Radio stations Cover pictures What should I do to move all this data to Rhythmbox, get it to work as the default music player, and smoothly switch completely to it?

• Prevent OCUnit tests from running when compilation fails

  - by mhenry1384

  I'm using Xcode 3.2.2 and the built in OCUnit test stuff. One problem I'm running into is that every time I do a build my unit tests are run, even if the build failed. Let's say I make a syntax error in one of my tests. The test fails to compile and the last successful compilation of the unit tests are run. The same thing happens if one of the dependent targets fail to build - the tests are still run. Which is obviously not what I want. How can I prevent the tests from running if the build fails? If this is not possible then I'd rather have the tests never run automatically, is that possible? Sorry if this is obvious, I'm an Xcode noob. Should I be using a better unit testing framework?

• SSIS Script Component Testing Strategy

  - by Paul Kohler

  This question is in respect to the script component specifically. I am aware of ssisUnit etc… With simple SSIS Scripts Components, it’s sufficient to let basic testing flesh out issues, however I am working with a script that has grown in complexity over time. To better test the functionality I am considering abstracting the script logic into a DLL that gets deployed with the package, and then use the custom component in the script. The advantage is that the function will be more testable etc but it’s one more deployment artefact that needs to be managed. My question is, does anyone know of a better way to test such an SSIS script in a more isolated manner than to run the whole package and examine the output?

• In Lisp, Avoid "Cannot open load file" when using require

  - by Jesse

  I am working on a custom .emacs file that I will be able to use on several different computers. I would like to be able to load a mode if it exists on the system. If it does not exist I would like Emacs to stop showing the error: File error: Cannot open load file, X. For example: (require 'darkroom-mode) Results in: File error: Cannot open load file, darkroom-mode I am using file-exists-p to test if certain other files exist but for this test I would assume I need to search my load-path. I am new to Lisp so this is stumping me.

• uWSGI loggin format unification

  - by Mediocre Gopher

  I'm attempting to unify the log format of my uwsgi instance. Currently there's three different types of log items: Sun Sep 2 17:31:00 2012 - spawned uWSGI worker 10 (pid: 2958, cores: 8) (DEBUG) 2012-09-02 17:31:01,526 - getFileKeys_rpc called Traceback (most recent call last): File "src/dispatch.py", line 13, in application obj = discovery(env) File "src/dispatch.py", line 23, in discovery ret_obj = {"return":dispatch(method,env)} File "src/dispatch.py", line 32, in dispatch raise Exception("test") Exception: test The first is an error spawned by uWSGI internally (I have the --log-date option set). The second is from the logging module, which has logging.basicConfig(format='(%(levelname)s) %(asctime)s - %(message)s') set. The final one is an uncaught exception. I understand that the uncaught exception probably can't be formatted, but is there some way of having uwsgi use the logging module for its internal logs? Or the other way around?

• Unit Testing iPhone Code That Uses NSLocalizedString

  - by Jay Haase

  I have an iPhone iOS4.1 application that uses localized strings. I have just started building unit tests using the SenTestingKit. I have been able to successfully test many different types of values. I am unable to correctly test any of my code that uses NSLocalizedString calls, because when the code runs in my LogicTests target, all of my NSLocalizedString calls only return the string key. I have added my Localizable.strings file to the LogicTests target. My question is: How must I configure my LogicTests target so that calls to NSLocalizedString will return the localized string and not the string key.

• Metsys.Bson - the BSON Library

  Earlier this month I detailed the implementation of the bson serialization we used in Norm - the C# MongoDB driver. I've since extracted the serialization/deserialization code and created a standalone project for it - in the hopes that it might prove helpful to someone. If you need an efficient binary protocol to transfer data, look no further. There are two methods you need to be aware of: Serializer.Serialize and Deserializer.Deserialize. User u1 = new User{...}; byte[] bytes = Serializer.Serialize(u1); User...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Creating a context in custom shoulda macro does not work.

  - by Honza

  I have a custom should macro in my test_helper.rb which looks like this. def self.should_require_login(actions = [:index]) if (actions.is_a? Symbol) actions = [actions] end context "without user" do actions.each do |action| should "redirect #{action.to_s} away" do get action assert_redirected_to login_path end end end if block_given? context "active user logged in" do setup do @user = Factory.create(:user) @user.register! @user.activate! login_as(@user) end yield end end end I would like to use it like this: should_require_login(:protected_action) do should "do something" do ... end end And I am expecting the "do something" test to run in the "active user logged in" context, but the test executes in the top context, like the "active user logged in" context never existed and I fail to see the reason why.

• New Pluralsight app for Android will bring variable speed

  Usually, it is very interesting to compare the 'same' software applications and apps between various platforms, and the Pluralsight offline players are an outstanding example to have a closer look at. The original Silverlight desktop offline player, the iOS app of Pluralsight and the new HTML5 online player all have variable playback speed. Just the Android app doesn't. But not for long. A couple of days Pluralsight finally announced that their development department found a reliable solution to provide flexible speeds. For the brave ones among us, please have a look at the public beta they are offering on their blog article.  Please be aware of, that using any Pluralsight offline player requires to have a Plus subscription. Otherwise, you cannot use the application after all.

• Zero division does not throw exception in nunit

  Running the following C# code through NUnit yields Test.ControllerTest.TestSanity: Expected: <System.DivideByZeroException> But was: null So either no DivideByZeroException is thrown, or NUnit does not catch it.

• Clickin issue in Flash and XML

  - by ortho

  Hi, I have the php backend that displays an xml page with data for flash consuming. Flash takes it and creates a textfields dynamicaly based on this information. I have a few items in menu on top and when I click one of them, data is taken from php and everything is displayed in scroll in flash. The problem is that if I click too fast between menu items, then I get buggy layout. The text (only the text) is becoming part of the layout and is displayed no metter what item in menu I am currently in and only refreshing the page helps. var myXML:XML = new XML(); myXML.ignoreWhite=true; myXML.load("/getBud1.php"); myXML.onLoad = function(success){ if (success){ var myNode = this.firstChild.childNodes; var myTxt:Array = Array(0); for (var i:Number = 0; i<myNode.length; i++) { myTxt[i] = "text"+i+"content"; createTextField(myTxt[i],i+1,65,3.5,150, 20); var pole = eval(myTxt[i]); pole.embedFonts = true; var styl:TextFormat = new TextFormat(); styl.font = "ArialFont"; pole.setNewTextFormat(styl); pole.text = String(myNode[i].childNodes[1].firstChild.nodeValue); pole.wordWrap = true; pole.autoSize = "left"; if(i > 0) { var a:Number = eval(myTxt[i-1])._height + eval(myTxt[i-1])._y + 3; pole._y = a; } attachMovie("kropka2", "test"+i+"th", i+1000); eval("test"+i+"th")._y = pole._y + 5; eval("test"+i+"th")._x = 52; } } } I tried to load the info and ceate text fields from top frame and then refer to correct place by instance names string e.g. budData.dataHolder.holder.createTextField , but then when I change between items in menu the text dissapears completely untill I refresh the page.
