Double Shot #586

It feels like there's a lot going on in the Rails world these days, even though Rails itself has not been shipping huge changes.

• CanCan - New authorization gem/plugin from Ryan Bates.
• Hobo 0.9.0 Released - This extension for Rails is in feature freeze for 1.0 now.
• 25 Tips for Intermediage Git Users - Some nice stuff here. I didn't know about 'git gui blame FILE' for example.
• EC2 Deployment with Rubber - Capistrano extension to provision and manage EC2 deployments.
