Ralf Wirdemann and Thomas Baustert have released Rapid Web Development mit Ruby on Rails. The first German book on Rails and published by Hanser. It should be available in stores from Monday, January 16th.
About the book, Ralf and Thomas write:
The book is a practice-oriented introduction into Rails and all of its sub-frameworks. The book focuses furthermore on some advanced topics as i18n with Rails or test-driven web development with Rails.
As a extra bonus, they’re even giving away a free introduction to Ruby that didn’t fit in the book. Congratulations, guys!
