Development with Ansible & VMs

Presented at DjangoCon US 2014

How do you set up a kick-ass dev environment? I'll share our team's setup and tools that give us a dev environment with superpowers: mirrors production; sets itself up with a single command; documented in code; repeatable and shareable. I hope you learn something you can put into action tomorrow!
