Ruby Science

The reference for writing fantastic Rails applications.

You build web applications, and you love Ruby on Rails because it provides a framework for developing applications that are are fast, fun, and easy to change. Over time these applications can become bloated, development slows down, and changes to the codebase become painful.

This book helps you learn to detect emerging problems in your codebase; and delivers the solutions for fixing them, while maintaining an application that will be fun to work on for years to come.

In addition to the book (in PDF, EPUB), Ruby Science includes a complete example Rails application.
