• Eclipse autocomplete not working in some Java files

  - by m_a_khan

  Hi, I have noticed that autocomplete is not working in some of java files in Eclipse. Also, the files where autocomplete is not working, display a hollow "J" as the icon for the Java file. The files where autocomplete is working, icon for java file is a filled "J" I am wondering if someone can point out what went wrong all of suddent, why the change in icons and why autocomplete and syntax highlighting is turned-off in the files with a hollow "J" icon? Thanks.

• it takes 2 seconds to compile a hello world C++ project in netbeans (windows)

  - by Ethan

  I used code:blocks as the C++ IDE on Windows. I switched to netbeans 6.8 (with C/C++ plugin, MinGW, MSYS) recently, because netbeas have the nice feature of "checking syntax errors when typing" (same as working on Java or PHP projects). But the painful thing is that, it takes 2 seconds to compile a simple hello world project in netbeans. Any trick to make it as fast as code:blocks, or at least make the compiling time no more than 0.5 second?

• Passing direct parameters to a Controller#method when testing via RSpec

  - by gmile

  Normally to pass parameters via in RSpec we do: params[:my_key] = my_value get :my_method Where my_method deals with what it received from params. But in my controller I have a method, which takes args directly i.e.: def my_method(*args) ... end How do I call the method with those args from within the test? I've tried get :my_method(args) but Ruby interpreter complains about syntax error.

• Why cast null before checking if object is equal to null?

  - by jacerhea

  I was looking through the "Domain Oriented N-Layered .NET 4.0 Sample App" project and ran across some code that I do not understand. In this project they often use syntax like the following to check arguments for null: public GenericRepository(IQueryableContext context,ITraceManager traceManager) { if (context == (IQueryableContext)null) throw new ArgumentNullException("context", Resources.Messages.exception_ContainerCannotBeNull); Why would you cast null to the type of the object you are checking for null?

• Way to partialy match a Ruby string using Regexp

  - by Fabiano PS

  I'm working on 2 cases: assume I have those var: a = "hello" b = "hello-SP" b = "not_hello" 1 - Any partial matches I want to accept any string that has the var a inside, so b and c would match. 2 - Patterned match I want to match a string that has a inside, followed by '-', so b would match, c does not. I am having problem, because I always used the syntax /expression/ to define Regexp, so how dinamicaly define an RegExp on Ruby??

• Are incremental Macro definition possible?

  - by Davorak

  I often find the following type of incremental definition useful: (define (foo) (display "bar")) (foo) ;prints bar (define foo (let ((bar foo)) (lambda () (display "foo") (bar)))) (foo) ;prints foobar How do I preform this type of incremental definition with macros? I could not get let-syntax to provide the same functionality. Currently I use plt scheme, but would like to see answers in different lisp implementations as well.

• Is my Joda Time format pattern incorrect to produce a `T` and `Z` inside the parsed DateTime output?

  - by Tree

  Using Joda Time's pattern syntax below, this input string: Sunday, January 09, 2011 6:15:00 PM becomes this datetime: 2011-01-09T06:15:00.000Z Code: String start = "Sunday, January 09, 2011 6:15:00 PM"; DateTimeFormatter parser1 = DateTimeFormat.forPattern("EEEE, MMMM dd, yyyy H:mm:ss aa"); DateTime startTime = parser1.parseDateTime(start); Is this format pattern incorrect? If not, what are the T and Z doing inside the DateTime output? 2011-01-09T06:15:00.000Z

• jQuery Prototype conflict, alternative solutions

  - by lbolognini

  I have a problem as I'm conditionally including the Prototype-based Lightbox script for IE6 as it works better than the jQuery plugin. Of course the two libraries conflict but the official solution is not really feasible for me as i would have to replace tons of $ with the alternative no-conflict syntax. Is there any other solution for me, keeping in mind that in my case it would be easier to have Prototype work nicely with jQuery than the other way around?

• Are there any FREE Xaml Diff/Merge tools available?

  - by Ahikam

  I am searching a free diff tool with support of native syntax and markup for XAML, but failed to find one. I like Altova's DiffDog but it's paid. CodeCompare is an useful tool. It has some worth with its integration into VisualStudio and usage of native editors. It's a perfect solution for XML! However, it does not support XAML editors. Who can recommend a diff tool for XAML?
