I have been learning the language ruby, and have begun playing around with ruby on rails. Which is a development framework for web based applications. I have been really impressed with ruby on rails so far, I was worried about how extendable it would be to less general problems, but it seems to be fairly extendable. Which is cool. I highly recommend giving it a shot and I think this was the best tutorial I have gone through while learning ruby.
Ruby on rails tutorial, building a cookbook
I also recommend Agile web development with Rails, from the Pragmatic Programmers
