Anything related to Linux.
The Phoenix Linux Users Group (PLUG) had their Westside meeting today. I attended it like I have been for the last couple of meetings. Several members had recently gone to SCALE in California, so most of the meeting was devoted to talking about what they did there. They said that it was a great learning experience, and a great way to meet many people that use free software. Hans even gave a presentation at SCALE which he went through with us. They are planning on going back next year and invite anyone that is interested to go along with them.
