We're going to have Wednesday's user group meeting focused on devops with a dive into Vagrant/Puppet.
Greg Lund-Chaix, Jeff Graham, and I will be talking about the various ways Vagrant & Puppet can make your life easier between development and production. I'll start with a very light intro about how to replace MAMP/XAMPP with Vagrant/Puppet and Greg and Jeff will demo some deeper concepts.
Also cool: Puppet Labs is sending over a few folks to hang out and provide more info on Puppet. Should be fun!
