Since launching Ruby Science we’ve written and released five new chapters. If you've previously purchased the book, you can log into GitHub to download the latest version.
Here's what we've added:
- Feature Envy
- Introduce Explaining Variable
- Introduce Form Object
- Move Method
The book is a work in progress, and we've now got around 60 pages of content. The purchase also includes an example application and support for any Ruby, Rails, and Refactoring questions you have. You can get access now for an early purchase price of $39. This will increase to $49 on January 31, 2013.
