Ruby is the fastest growing and most exciting dynamic language out there. If you need to get working programs delivered fast, you should add Ruby to your toolbox.
This book is the only complete reference for Ruby 1.9, the very latest version of Ruby.
Ruby 1.9 is the latest version of Ruby. It has many compelling features, including multinationalization support, new block scoping, and better performance. At the same time, the current Ruby 1.8 is still being maintained and is widely used. We're therefore releasing both the Ruby 1.9 version of the PickAxe (this book) alongside the 1.8 version of the PickAxe. Readers can choose the book that matches their environment.
For developers who have learned the elegant and highly productive Ruby language, it can be a real drag to switch back to a traditional static programming tool like Objective-C. MacRuby, a Ruby 1.9 implementation that sits directly on the Mac OS X core, gives Rubyists the potential to code Cocoa apps without sacrificing the language features they've come to depend on.
