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.
