Currently working on doco for SE Linux (NSA Security Enhanced Linux). There isn't much out there in the way of a introduction/Howto so I thought I'd write one myself. The focus is largely on Debian but I'm trying to be as general as possible. Check out SE Linux if you haven't already.
Been stuffing around a lot with IPSec, got it happily running but will probably write some doco up on that as well as I was initially frustrated with available notes out there. Or maybe I didn't look hard enough *shrug*
Hacked my Debian and Linux tshirts. With a scissors that is. I look forward to the day conferences will sell fitted boobtubes as well as the standard unflattering male geek t-shirts ;)
