I’ve been trying to learn a bit more about the Ruby programming language. It’s been going very slowly since I don’t have a lot of time to devote to it, but here are some of the resources that were given to me by a colleage who is into Ruby:

I normally refer to the Pragmatic Programmer’s Guide — http://rubycentral.com/book/. The online one is the 1st edition; there’s a 2nd edition, which I don’t think is available online. Also, if you’re kinda fine with spending too much time, the Poignant Guide is kinda fun — http://poignantguide.net/ruby/.

Also, I have a few Ruby presentations online: http://premshree.org/presentations/

As for Rails, I’d recommend a tutorial like the one on onlamp: http://www.onlamp.com/pub/a/onlamp/2005/01/20/rails.html
