GitHub
I've got myself an account on GitHub and I'm using it to publish several repositories. The first two are melody and websong: the core of Project Melody and its web frontend based on CherryPy. feed.sheet is a Melody repository (aka sheet) that wants to be a feed browser. wide_finder and asyncgen are related to the Wide Finder project: wide_finder contains my experiments with Python code; asyncgen is a parallelization library that I developed for the project.
I hoped to write a longer article on each of them, publishing the code at the same time, but that way I'll never get them out the door. Hopefully I'll be coming back with conclusions on the Wide Finder experiment one of these days - Tim is rounding up code and results and it would be nice to contribute something useful.

Were you able to compile stackless successfully Solaris 10?
An another alternative would be using greenlets. However it doesn't seem to compile under Solaris 10.
I even submitted a report in the py-dev mailing list.

I never got as far as compiling Stackless on Solaris, because I realized it's not a solution for my problem: it still has the GIL; what I needed was real concurrency.
