Ruby on Rails is huge. Even if you have worked with it for a long time, it’s unlikely that you have stumbled across everything yet. Do you really know what all of the built-in Rake tasks do? Have you seen all of the methods ActiveSupport makes available to you? Are you aware of all the queries ActiveRecord is capable of? Explores the extras of Rails and see if you can’t turn up some features that you don’t see all of the time, but that might just be handy to know about anyway.
