This video comes from the Silicon Valley Linux Users Group and is dated Nov. 7, 2007. Pretty darn interesting for us non-programmer types who want a better idea of the structure of the Linux kernel.
Meet up with Montana Linux people on IRC. We currently gather at the #ubuntu-montana room on the freenode network. Stop in and say "hello" or even ask/answer some questions. Don't have to be a Ubuntu user either. Or use the web-based chat client.
