Sleep Sort in OTL

I found Sleep Sort so ingenious (in the mad genius way) that I just had to implement it using the OmniThreadLibrary framework.

The code is now shorter than Serg’s original implementation and it’s … wait for it, wait for it … even faster! Twice as fast as the original, actually! Now that I call an improvement!

The code below carries not copyright nor copyleft and can be used in any occasion as long as you don’t blame me for getting fired or any other problems in your personal or professional life it may cause.

Lock-free vs. Locking: Rematch!

My article on lock-free vs. locking data queues was well-received but there were also some comments and complaints. To answer the critics (your comments were all very appreciated!) and to fix some issues with the previous test I’ve decided to stage a rematch.

New contestants

Both Iztok and Chris have provided me with new versions of their queue implementations. Iztok’s code was tuned a little and changed to use TOmniValue instead of TAnyValue for better comparison with TOmniQueue. Chris has created three different variants of his code.

OmniThreadLibrary Needs YOU!

That is, if you are a C++Builder programmer and want to help an open source project.

The problem with OmniThreadLibrary and C++Builder is very simple – I’m not using it. (The C++Builder part, obviously.) Therefore I’m not checking for compatibility with C++Builder and I cannot fix the stuff if it doesn’t work. (In C++Builder.)

And now a user reported that the OTL doesn’t compile. In C++Builder. And I don’t know how to help him. With his problems. In C++Builder.

Is there a nice soul out there that can tell me how to fix the problem? (Or even better, who can make sure that the OmniThreadLibrary compiles with C++ Builder.) Your fixed will be gratefully imported into the main development branch and you’ll earn an eternal fame.
