Welcome to this week’s Web-based syndication of Ruby Weekly, the Ruby e-mail newsletter (which just turned 100 weeks old this week – issue 100! :-))

Highlights include: Ruby 1.8.7′s last ever bug fix release, the Ruby OpenSource Challenge, a new open source code review system, and the results of a Rubyist text editor poll.

Welcome to this week’s Web-based syndication of Ruby Weekly, the Ruby e-mail newsletter.

Highlights include: MagicRuby 2012, a code structure/patterns ‘drama’, Mark Bates’ new CoffeeScript book, minitest 3.2.0, and the Ruby Rogues chatting with Jim Weirich (who I met for the first time this week, ironically at a JavaScript conference!)


‘Programming in CoffeeScript’ by Mark Bates, Now Available
Mark Bates, a Ruby developer, was won over by CoffeeScript and has written a book for Addison-Wesley which has now been published. Despite being a language that compiles down to JavaScript, CoffeeScript has become relevant to Rails developers in recent times given its inclusion in Rails 3.1+. Read More

Welcome to the bumper pick’n'mix of Ruby and Rails news and releases for May 2012, fresh from the pages of Ruby Weekly (which, unsurprisingly, comes out once every week – on Thursdays).

Highlights include: RubyMotion’s release, the JRuby guys are moving to Red Hat, Spree 1.1, DHH’s RailsConf keynote, and JRuby 1.7.0 preview 1.

Breaking news! At JRubyConf 2012 (a 3 day JRuby-focused conference in Minneapolis) it has just been announced that JRuby core team members Thomas Enebo and Charles Nutter are moving from Engine Yard to open source giants Red Hat.

The news was confirmed by Nutter in a tweet:

Engine Yard shares their side of the story and says they’ll continue to “work closely with Charles and Tom as well as Red Hat to continue development of JRuby and collaborate on JRuby features to support customers running on JRuby on Engine Yard Cloud.”

From the Red Hat perspective comes this post by JBoss director Mark Little. Read More

RSpec 2.8: The Popular Ruby BDD Tool Goes Supersonic
RSpec 2.8 and rspec-rails 2.8.1 have been released and some users have been reporting significant performance improvements. Other tweaks include improved documentation, better tag and filtering options, random example execution, and ‘rspec –init’ for adding RSpec to an empty Ruby project. Read More

RSpec 2.8 has been released, along with rspec-rails 2.8.1 for the full Rails 3.x integration experience.

RSpec is a BDD-focused testing tool that’s particularly popular in the Rails world where everyone except DHH is using it (if you believe the hoopla). RSpec has faced accusations of being less than speedy in the past, but it seems 2.8 has had a performance firework shoved up its tailpipe:

David Chelimsky, the creator of RSpec, also notes that in RSpec 2.8:

  • the documentation has been significantly improved
  • there’s improved support for tags and filtering
  • random example running order support (with user definable seed)
  • rspec –init will create a spec directory and some starter code on a blank project – ideal for Ruby library development!
  • Read More

Ruby isn’t known for its game development chops despite having a handful of interesting libraries suited to it. Java, on the other hand, has a thriving and popular game development scene flooded with powerful libraries, tutorials and forums. Can we drag some of Java’s thunder kicking and screaming over to the world of Ruby? Yep! – thanks to JRuby. Let’s run through the steps to build a simple ‘bat and ball’ game now.

The Technologies We’ll Be Using


If you’re part of the “meh, JRuby” brigade, suspend your disbelief for a minute. JRuby is easy to install, easy to use, and isn’t going to trample all over your system or suck up all your memory. Read More
