Bruce Tate, this time on moving from Java to Ruby

Bruce Tate is at it again, this time writing for the Pragmatic Press, called "Java to Ruby", on... well, the title kinda says it all, on migrating from Java to Ruby. It's not just a "blind adoption" book, meaning it just blindly advocates the transition, but instead Bruce discusses the risks involved with making the switch, and how to justify it to upper management. Don't get me wrong, he's operating from the basic conclusion that you want to make the switch, so if you're not yet convinced that Ruby or Ruby-on-Rails is the way to go, you're not necessarily going to be any more convinced by this book. But if you are already convinced (and in Bruce's defense, there's lots of good reasons to be), this looks to be the book to help you convince others, most notably your management.
