If you are developing web applications under J2EE just like me, and also grew increasingly curious about all that hype around
Ruby on Rails lately, you might want to have a look at the
screencasts available at rubyonrails.org. Having watched some of the presentations, it's certainly too early to draw any conclusions yet. All I can say is that Ruby on Rails looks like an extremely productive environment. Hacking prototypes that way seems like a very natural thing to do. On the other hand, there is a lot of magic going on. And I don't like magic, at least not too much of it. I am also one of those old-fashioned developers who prefer to pass their code through a compiler before running it. Still, I will definitely take a closer look on Ruby on Rails as soon as my schedule allows me to.
