hmm, might be useful.
Somethings I'd like to work on, are using git, cvs, or svn. My own system here runs CVS, since that's what OpenBSD comes with, but I'm more used to workign with Subversion. Git and Bazaar-ng are two programs I really should evaluate, since git is likely a program I would love using, and bzr is one I may find more useful in the wider world.
It also pays to know svn/cvs, hehe.
