It really makes me happy to see the increasing international interest in Rails and in Ruby. As I reported earlier, the official Ruby site is available in many languages (currently English, French, Japanese, Korean, Polish and Spanish), with more in the works. My original Rolling with Ruby on Rails was translated into Japanese, French, and Spanish. And now Bill Walton’s updated version of Rolling with Ruby on Rails has been translate to Brazilian Portuguese thanks to Gabriel Bogéa Perez!
Of course there is much more. If you know of Ruby and Rails resources in other native languages, please post the links in a comment and tell the rest of us about it!
