I have another page for JRuby
few books that I read, and recommend:
The Well-Grounded Rubyist is best ruby book I've ever read. I'll extract notes from my e-reader later.
Practical Object-Oriented Design in Ruby is a good book on OOP, I borrowed from library, no notes were taken. Probably will read it again.
Ruby Under a Microscope is another good book, couldn't finish yet.
Ruby Best Practices, this one is quite difficult, couldn't finish.
