Rar. Details are here. One of the things I plan on working on is Perl + DTrace.
As an aside, I'm experimenting with what I'm calling a "Personal Planet" (no idea if that's already been coined, it just came to me). Having heard numerous people rave about Plagger I've set up an installation to aggregate feeds from the various places that I might publish content. Here, the previously linked blog, RSS feeds of commits to my Subversion repo, etc. You can see the result here. Since this post is going to be included in that feed it's all going to feel a bit meta.
