Ruby Resource

"Take a true object-oriented language, such as Smalltalk. Drop the unfamiliar syntax and move to more conventional, file-based source code. Now add in a good measure of the flexibility and convenience of languages such as Python and Perl. You end up with Ruby."

The Pragmatic Programmer's Guide to Ruby is a nice resource to examine and make use of if you are just starting out with Ruby or you wish to fine tune some of your Ruby skills.
