Double Shot #888

Another jackpot number.

• [ANN] Rails 3.0.13.rc1, 3.1.5.rc1, 3.2.4.rc1 have been released! - Why yes, they have.
• rubymotion_cookbook - Project to rewrite the examples from the O'Reilly iOS5 Programming Cookbook into ruby.
• Media Queries in Sass - A gist of useful code.
• Plain Record - Data persistence layer that uses human readable text for storage.
• Abstraction Creep - An argument that you should fix shaky abstractions, rather than build another abstraction on top. Sounds sensible, but I think of the Rails-Merb merger and think it's not that simple.
• Redactor - jQuery-based WYSIWYG editor.
