Kind of surprised no one has mentioned JRuby yet.

One of its strengths is the ability to natively call Java classes, so you can use a lot of the frameworks from Java that you're already familiar with.


Downloading the Ruby Koans is another great way to learn http://github.com/edgecase/ruby_koans


Pragrog books are always good:

Start here:

Once you do the 15 minute walk-through, go here:

Programming Ruby: The Pragmatic Programmer's Guide


To Ruby from Java:

http://www.ruby-lang.org/en/documentation/ruby-from-other-languages/to-ruby-from-java/

That is the official site for Ruby and will be able to point you to language downloads and other resources.


How about the Ruby language web site: http://www.ruby-lang.org/en/

Also, I would advise you not to try and come across as a ruby expert in the interview after only playing with it for a month. It's better to err on the side of honesty, because a good interviewer will be able to tell when you are faking it... or worse, it will show when you start working.

Ruby is a cool language... have fun!
