• Gutter - Server monitoring as a Rails engine.
  • Shoulda Matchers 2.8.0 - The latest version of Thoughtbot's test helpers for validations and associations, complete with Rails 4.2 support.
  • Announcing MongoDB 3.0 - Plenty of hype here, but looks like some good feature advances as well. I'm still skeptical that it is "the new DBMS standard".
