I’ve been quite impressed by the “Addison-Wesley Professional Ruby” series of books (I’ve got The Ruby Way and RailsSpace) as well as the work of series editor Obie Fernandez, whom I had the pleasure of meeting at RailsConf 2006. That — along with glowing reviews for both books plus my serious immersion into Ruby and Rails at TSOT — is why I’ve got Design Patterns in Ruby and The Rails Way on order. I’m looking forward to getting my paws on these books, and I’ll post reviews shortly afterwards.
(I’m normally pretty conservative when it comes to spending on computer programming books for the past little while, but that’s because evangelism rather than programming has paid the rent. That situation has changed somewhat.)
Both Design Patterns in Ruby and The Rails Way are in Antonio Cangiano’s set of recommended Ruby and Rails books. If you’re looking to get into either Ruby or Rails (or if you’re already into either and just looking for related reading material), check out his list.
