Ruby on Rails Tutorial: Learn Rails by Example

A major aid in my attempted progress in understanding Rails and Ruby programming has been Michael Hartl's excellent Ruby on Rails Tutorial. He takes the reader through literally every step of building a database-backed web application in Ruby on Rails, and he assumes virtually no prior knowledge. Three things make this tutorial especially valuables. The tutorial:

1. is based on Rails 3, but includes a parallel course on Rails 2.3;
2. includes steps on how to deploy on Heroku; and
3. includes test-driven development with Rspec.

 There are many more reasons why this tutorial is great, but those three should be enough to merit a look by most of us would-be developers. Thanks Michael.
