Double Shot #1074

Yes, there's a new Rails beta. Watch out, world.

• Rails 4.0: Beta 1 released! - It's out, with all sorts of changes. Definitely budget plenty of time for upgrading and testing.
• Literate Ruby - Inspired by Literate CoffeeScript.
• unrefine - Get rid of refinements from Ruby 2.0, so you don't have to figure out this "experimental" feature. Or perhaps you'd prefer safe unrefine, which uses refinements to do the job.
• Maintenance policy for Ruby on Rails - What you should expect from various versions.
• Ruby 2.0 Walkthrough: The Best Bits - From Peter Cooper.
• How to Use Trello Effectively (What Worked for Our Small Team) - One point of view. Some day I should write up how we use it.
• Hook.js - "Pull to refresh. For the web."
• The easiest way to test Ruby 2.0 - The Bitnami Rubystack has been upgraded.
