Welcome to this week's Web-based syndication of Ruby Weekly, the Ruby e-mail newsletter.

Highlights include: MagicRuby 2012, a code structure/patterns 'drama', Mark Bates' new CoffeeScript book, minitest 3.2.0, and the Ruby Rogues chatting with Jim Weirich (who I met for the first time this week, ironically at a JavaScript conference!)
