The Most Comprehensive and Up to Date Walkthrough of Ruby 1.9 for Existing Rubyists.

The Ruby 1.9 Walkthrough is a thorough, up-to-date video-based walkthrough of Ruby 1.9.2 and 1.9.3! What's new? What's gone? What's different?

I'm Peter Cooper, the author of Beginning Ruby and editor of Ruby Inside. I created The Ruby 1.9 Walkthrough because the "What's new in Ruby 1.9?" articles I've found are either out of date (a lot has changed) or only skim the basics.

This screencast is the most thorough and up to date guide to Ruby 1.9 from the Ruby 1.8 perspective.
