I had a great time at POSSCON 2012, met up with Steve Graham (a fellow Triangle Resident), got to talk to Jon 'Maddog' Hall, and a whole host of Open Source luminaries. I even learned what a Palmetto is. My talk was An Introduction to Grails where in I live code while explaining each line. The source code is up on github now if you want. The slides are naturally available below: POSSCON is definitely a conference you should check out.
