I've been doing allot of work on CKS to support a developing standard for PKS Keyserver protocol. A new release should happen after Q2 finally ends and everyone at work stops working like crazy to try and squeeze stuff into the quarter.
I've discovered valgrind, and it has helped me find some memory leaks in various code I have written. It's worth taking a look at if you're developing with C/C++. There's even a howto to get you started. I think the coolest thing about it is that for me it's kind of like a spellchecker, after it has me correct an error once or twice I learn the correct way and don't seem to make that mistake any more. My code is much better for having used it.
I set up a Gnutella Web Cache to help people bootstrap onto the Gnutella network and share free software. It's at http://gwc.fspn.cryptnet.net/. I started working on the Gnutella Web Cache code to improve its efficiency.
I'm getting much better w/ my acoustic guitar. I've been practicing a great deal lately. I've been thinking about working on some music/guitar related software for Linux and some open content. Any other guitar players here on advogato?
