By

Sometimes the old adage rings true: the best things in life are free. If you've wanted to learn a little Ruby, but haven't been able to fit a programming course into your budget, don't worry. There are a number of places on the Web to begin your learning, without sacrificing money or quality.

The Pickaxe Book

One of the first versions of the venerable Programming Ruby (better known as the "Pickaxe Book") is available for free online. While it was written for Ruby 1.6 and was published in 2000, this can still be a very useful book for any beginning Ruby programmer. All of the fundamentals have gone unchanged, and all the code presented in this book still works! The authors (Dave Thomas, Andy Hunt and Chad Fowler) are respected and known Rubyists.

Mr. Neighborly's Humble Little Ruby Book

A one-man project, Mr. Neighborly's Humble Little Ruby Book is available free as HTML or a PDF, but also as a book from the on-demand publisher lulu.com. This book covers all the basics, and is more recent than the free version of the Pickaxe Book. Published in 2006, it covers the 1.8.x version of Ruby.
