Continuous CoffeeScript testing with Guard and Jasmine

This Gist shows how to set up a Rails project to practice BDD with CoffeeScript, Guard and Jasmine. You can see this setup in action on Vimeo

Install Gems with Bundler with bundle install
Define your guards with mate Guardfile
Initialize Jasmine with bundle exec jasmine init
Configure Jasmine with mate spec/support/yasmine.ym
Start Guard with bundle exec guard

Instrument Anything in Rails 3

With Rails 3.0 released a few weeks ago I've migrated a few apps and I'm constantly finding useful new improvements. One such improvement is the ability to log anything in the same way that Rails internally logs ActiveRecord and ActionView. By default Rails 3 logs look slightly spiffier than those produced by Rails 2.3: (notice the second line has been cleaned up)
