This looks fantastic. I'm currently writing my first practical Rails app and using APIs for the first time (the Tumblr API specifically). The app works, but I need to move the API calls to a background process and I haven't been able to get that to work yet. Does your book cover background processes?

It covers a lot of steps that are missing from your instructions. http://moncefbelyamani.com/how-to-install-xcode-homebrew-git-rvm-ruby-on-mac/ http://moncefbelyamani.com/how-to-install-xcode-homebrew-git...
