I just bought a ticket to Fossetcon happening September 11-13th, 2014 in Orlando, FL. Fossetcon is the Free and Open Source Expo and Technology Conference.
The three day event includes one full day of training classes, plus lunch during the training day, for $20! I am very excited to see how this goes as it seems like an incredible deal. If you are in Central Florida and like free and open source software check it out. For $20 you can hardly go wrong. http://fossetcon.org/
