Revitalized by Ruby on Rails, the Ruby language continues to grow in popularity. Books like this are necessary to fill the demand. Here is a classic of its kind; required reading for Ruby programmers who have already mastered the basics and want to learn higher level techniques. Practical Ruby Projects presents nine diverse projects that will teach new and innovative techniques in a learn-by-example fashion. They include a turn-based adventure game and a generative music creator. While there are many other Ruby titles, none of them take this unique project-based approach to teaching.

Topher Cyll is a software engineer and writer living in Cambridge, Massachusetts. He received his bachelor's degree in computer science from Williams College and works for a small Boston-area startup. In reverse alphabetical order, he finds programming languages, music, free software, education, bioengineering, and beer terribly exciting. Topher loves Ruby not only for the language itself, but also the light-hearted and intellectually curious community that surrounds it.
