9 months in the making comes RSpec 2.0, the latest major version of Ruby's most popular behavior driven development (BDD) framework (now at a gem install rspec near you). Kudos to the 82 contributors and RSpec's team lead, David Chelimsky.

Just a month ago, David Heinemeier Hansson welcomed Rails' newest core team member, Santiago Pastorino. Strikingly, Santiago only started to contribute code to Rails earlier in the year and it's not every day that DHH is trumpeting someone else's productivity, so I had to catch up with him and learn his story.

After 5 months of development, we are happy to announce the immediate availability of MacRuby 0.7. This release does not bring any significant features but consolidates the existing functionality of MacRuby by improving its Ruby compatibility, concurrency, Cocoa support, and overall stability and performance.

Charles Max Wood of Teach Me To Code Screencasts has put together a 13 minute screencast demonstrating how to use some Ruby metaprogramming magic along with Rack in order to build a small Sinatra-esque webapp framework. Watch the HD version at Vimeo or download the video to get the best quality.

Let's straight into it. There are currently 10 great positions being advertised on the Ruby Inside jobs board. Here's a roundup:

Version 1.1 is the latest release of Rubinius, a Ruby implementation based around a C++ and LLVM virtual machine but with the bytecode compiler and majority of the core written in Ruby itself. It's often called a "Ruby in Ruby." We celebrated and explained the background to Rubinius' 1.0 release 4 months ago.

It's time for us to thank the companies who help keep Ruby Inside (and often other Ruby sites) going by sponsoring our work. Luckily, they're all pretty interesting in their own right and have some worthwhile products and services to check out (and Linode recently put their prices down!).

A couple of weeks ago, I wrote about RubyDoc.info, a "good looking, up-to-date Ruby documentation" site powered by YARD. Well, as of YARD 0.6 you can get the same greatness that RubyDoc.info provides applied to your local machine's collection of gems in just a few steps. Try it out - you won't regret it.

It's been a great year for Ruby on Android, but no one knows it. You can start writing Ruby apps for Android devices TODAY. You don't need to install any SDK, you don't need to install some giant Eclipse IDE, and you certainly don't need to write any Java.
