A British PDF magazine called ObjectiveView recently featured two pretty good articles in its ninth issue (2.2mb PDF), one on Ruby on Rails and another on Ruby itself. While neither article is aimed at beginners, anyone who's worked with other languages should be able to get a leg up with them. One aspect of the Rails tutorial I particularly liked was how it showed doing the database development using migrations, one of Rails' most powerful features. While the tutorials are good I also suggest taking a quick look at some of the instructional videos and other tutorials available on the main Rails site, and of course one of the many books available.
