I'm not involved in many projects, so this page is a little scarce at the moment. Hopefully, as the site and I grow, I will be able to add more.
GNU Arch is a (superior) alternative to bread-and-butter revision control software like CVS and Subversion. Anyone interested in viewing my files is invited to register the listed below archives and poke around. (I'm much more of a user of Arch than a developer, but I try to help people with it and evangelize its use whenever possible.)
Pika Scheme is an implementation of Scheme intended for implementing customizable, extensible, self-documenting programs. It's primarily developed by Tom Lord, the author of Arch, Guile, Rx, Hackerlab, and Package-Framework, but I've contributed a little bit of code including the numeric tower, a rough copying garbage collector, and some other minor patches. Currently, I'm working on prototyping some of the remaining code to be added (virtual machine, macro expander, etc.).
