Ruby on Rails 2.2 Screencast, by Gregg Pollack and Jason Seifer

I bought (9$) and watched the Ruby on Rails 2.2 screencast from Gregg Pollack and Jason Seifer. The short review: good value for my money!

As shown on their website, the screencast includes:

  • Scaling with Etags => excellent and instructive explanation
  • Connection Pooling => excellent and instructive explanation
  • New Enumerable Methods => not very valuable to my taste
  • The New Test Helpers (using ActiveSupport) => useless when using shoulda or RSpec
  • Internationalization (i18n) => barely touched on

Most of the time is spent in ActiveRecord and ActiveSupport (17 out of 44 min). They show the old way of doing things with a code sample (as it was done before 2.2), along with the new way in 2.2. They also bring in a few new 2.2 features.

Although not an exhaustive review of the Rails 2.2 features, it’s a pretty good summary in a very original format. Being very pedagogical, they are fun to watch and easy to follow.

I’m up for some more from those guys!
