Ruby Reference Guide
The following links are good pages to keep handy while you're programming Ruby.
Ruby Class and Library Reference - All the base Ruby classes and references
Programming Ruby - The Pragmatic Programmers Guide - This is the first edition (online for free) of the Pick Axe Book
Ruby Quick Reference - A one page quick overview of Ruby Documentation.
If you have a problem and none of the references can help you, try these links:

Ruby Mailing List / Forum - These are the ruby mailing lists in forum format, which are very searchable.
