I’ve caught a few mistakes in GKTapper. Read on to see how the sample performs invalid caching of achievements and to see how it shows incorrect string as leaderboard description in one place.

You may be tempted to recommend Dev-C++ to a beginner, or you may be a beginner tempted to use it.
Stop.
It’s 2011. Dev-C++ is not in development since 2005. Its latest version is a beta, and as you code, its beta status will be felt. Here is a short list of why a beginner should not use Dev-C++, and why he will not miss it after no longer being a beginner. Of course, this is also a list of reasons why competent and advanced coders should not use it. (Update March 28 2012: Here’s an additional opinion from way back in 2008.)

A few months ago I wrote about a necessity for HTML5’s success: a design tool similar to Flash.
Well, here it is: Ajax Animator. Test it:
If you are a Cocoa or Cocoa Touch developer, you may have attempted to use features such as properties in GNUstep, only to be surprised that these don’t seem to be supported. This is because these are Objective-C 2.0 features.
To get the new features, the only way is to use a different compiler called clang. You may have seen this compiler used in newer releases of Xcode. This is a compiler that targets a virtual machine called LLVM before producing native code.
UPDATE May 4th 2011: GCC 4.6 has got the Objective-C 2.0 treatment, and since Debian includes GCC 4.6, I’d recommend you to try compiling your software that way. Not because it’s a better compiler — I have no idea which one works better — but because it’s there. Also, consider compiling GNUstep from trunk using GCC 4.6; it’s rather easy to do. (CC=gcc-4.6 ./configure, whenever compiling a component of GNUstep).
Let’s presume you managed to run an Objective-C program with GNUstep; that is, let’s presume you are aware of Project Center, or GNUmakefiles. If you are didn’t use GNUmakefiles, you should know that Project Center generates these in order to build your app.
Now you want to switch to clang, and you want to do so on your favorite operating system, Debian GNU/Linux.

Here’s a little multiuser chat server written for various POSIX-compatible operating systems. Written and tested on Mac OS X 10.6, but it should work on your favorite Linux, too.
Placed in public domain, use it for whatever you want (since it’s so simple). 177 lines of pure C powah, dood.
Code follows after the break.

I added fake caps&features to Z-XMPP to simulate iChat’s AV support. List of the caps&features that I added:
this.features.push("apple:profile:bundle-transfer");
this.features.push("apple:profile:efh-transfer");
this.features.push("apple:profile:transfer-extensions:rsrcfork");
this.features.push("http://www.apple.com/xmpp/message-attachments");
this.featuresExt["ice"] = ["apple:iq:vc:ice"];
this.featuresExt["recauth"] = ["apple:iq:vc:recauth"];
this.featuresExt["rdserver"] = ["apple:iq:rd:server"];
this.featuresExt["maudio"] = ["apple:iq:vc:multiaudio"];
this.featuresExt["audio"] = ["apple:iq:vc:audio"];
this.featuresExt["rdclient"] = ["apple:iq:rd:client"];
this.featuresExt["mvideo"] = ["apple:iq:vc:multivideo"];
this.featuresExt["auxvideo"] = ["apple:iq:vc:auxvideo"];
this.featuresExt["rdmuxing"] = ["apple:iq:rd:muxing"];
this.featuresExt["avcap"] = ["apple:iq:vc:capable"];
this.featuresExt["avavail"] = ["apple:iq:vc:available"];
this.featuresExt["video"] = ["apple:iq:vc:video"];
And here’s what I get when I press call:
