• How do I call a non-public method of a public class in Clojure?

  - by sramsay

  I'm calling the twitter4j library using Clojure like so: (def twitter (. (TwitterFactory.) getInstance)) This works fine when I call it as a script. But when I use gen-class, I get: java.lang.IllegalArgumentException: Can't call public method of non-public class: public java.lang.Object twitter4j.TwitterFactoryBase.getInstance() Is there a workaround for this?

• ConcurrenctBag(Of MyType) Vs List(Of MyType)

  - by Ben

  What is the advantage of using a ConcurrentBag(Of MyType) against just using a List(Of MyType)? The MSDN page on the CB (http://msdn.microsoft.com/en-us/library/dd381779(v=VS.100).aspx) states that ConcurrentBag(Of T) is a thread-safe bag implementation, optimized for scenarios where the same thread will be both producing and consuming data stored in the bag So what is the advantage? I can understand the advantage of the other collection types in the Concurrency namespace, but this one puzzled me. Thanks.

• Python: Container object that preserves ordering and enforces uniqueness?

  - by Infinity

  Is there anything like this in the standard library? I've looked but haven't found it. It needs to be like a list (preserves order) but also like a set (elements can only appear once). So if you give it ['a', 'b', 'a'] it should return ['a', 'b'] Thanks!

• How to resize an image smoothly (with resampling) using Windows API calls?

  - by Clay Nichols

  I need to resize images and resample them so they don't end up all jagged (I think that's called aliasing). I found some code (sorry, lost the link) that does this in pure VB6 code but it's a bit slow (2-5 seconds) and I'm displaying pictures in real time so I need something faster. I seem to recall seeing some examples of doing this with the GDI+ library. An example in VB6 would be ideal, but I can probably work with a simple example with Windows API calls in another language.

• Audio processing libraries for Ruby?

  - by J. Pablo Fernández

  Any recommendation on libraries to do audio processing in Ruby. I need to do the following two tasks: Find silences, for which I'm happy to just be able to iterate over each sample in the wave. Cut and paste pieces of wav files to form a new wav file. Convert wav to mp3, which I will probably leave to lame anyway. I'm looking for the equivalent of NAudio, a C# library.

• Do you know of some performances test of the different ways to get thread local storage in C++?

  - by Vicente Botet Escriba

  I'm doing a library that makes extensive use of a thread local variable. Can you point to some benchmarks that test the performances of the different ways to get thread local variables in C++: C++0x thread_local variables compiler extension (Gcc __thread, ...) boost::threads_specific_ptr pthread Windows ... Does C++0x thread_local performs much better on the compilers providing it?
