The power of software is the power of thoughts and ideas.
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.
