Double Shot #388
Well, after joining the Rails Activists and the creation of ActionRails, I can finally complete my trifecta of Big Announcements for the year: I'm co-authoring Rails 3 In Action, to be published by Manning late this year. UPDATE: No, as it turns out, I'm not. For various reasons, I've dropped out of that book project.
Clearance: Rails authentication for developers who write tests - Yup, one more authentication library, this one from the ThoughtBot guys.
RSpec and Shoulda - Using the two together for maximum goodness.
