If you head on over to the projects page, you'll find links to a
number of projects over on SourceForge.net.
They are:
perftools: different libraries and tools
to help tune and debug your multi-threaded c++ programs. coredumper: Gives you the ability to dump cores from programs when it
was previously not possible. goopy/functional: brings functional
language behaviors to python. sparsehashtable: brings a variety
of new hash tables to C++.
Each has a Google group that you can
participate in and we hope you find them as useful as we do!
