A couple months back I had the pleasure to attend the 2nd ever DerbyCon event down in Louisville, KY. This was the best conference of the year. DEFCON is great but you get all the feel of DEFCON with 1/10th the people and none of the clicks. This was truly one big group to have fun and learn about security. It was also nice to have multiple defensive talks. While I understand that DEFCON and BlackHat are offensive conferences it was nice to have a mix of both especially when there wasn’t a bunch of vendor sponsored talks. In fact I sat in on a couple talks that were specific to FOSS tools.
