Comes in both male and female styles in varying sizes. Only available for 6 more days though as it's part of a temporary Teespring campaign (Note: I have no connection to this, it just looks cool.) David Chelimsky Hands Over RSpec to New Project Leads http://blog.davidchelimsky.net/2012/11/28/myron-marston-a... After several years at the helm, David Chelimsky is handing over the reins to Myron Marston and Andy Lindeman for RSpec and rspec-rails respectively. Thanks for all your hard work, David. Upgrading to Rails 4: A Forthcoming Book (in Beta) http://www.upgradingtorails4.com/ Andy Lindeman of the RSpec core team is working on a new book designed to bring you up to speed with Rails 4.

It may sound obvious but Unicode whitespace and regular ASCII spaces are not the same thing and this can cause problems in Ruby. But once we get over the initial problems, you can torture your pair, terrify your audience, or just give yourself a laugh by putting Unicode's non-breaking spaces to evil use. Making Your Ruby Fly http://alisnic.net/blog/making-your-ruby-fly/ Andrei Lisnic demonstrates a few compile time 'tricks' you can use to make your MRI Ruby 1.9.3 faster. The benchmark results are compelling. Avoiding the Tar Pits of Localization http://blog.localeapp.com/2012/11/21/avoiding-the-tar-pit... Jeff Casimir gave a talk on the 'Ruby Hangout' about the trickiness of handling internationalization and localization and some tools and libraries you can use to help. Lots of notes here or you can watch the video. Recovering From Segfaults in Ruby, The Sneaky Way http://charlie.bz/blog/recovering-from-segfaults-in-ruby We've probably all seen the dreaded 'segmentation fault' from Ruby before. Charlie Somerville demonstrates a rather clever but sneaky way you can 'recover' from them in plain Ruby. As he says, you probably don't want to use this trick seriously. Use Rails Until It Hurts http://evan.tiggerpalace.com/articles/2012/11/21/use-rail... Evan Light pushes back a little against the recent wave of OO purity and, as DHH calls it, 'pattern vision.' Speeding Things Up With jRuby http://www.mutuallyhuman.com/blog/2012/11/26/speeding-thi... MRI's global interpreter lock prevents running code in parallel without forking the Ruby process. That's where JRuby can help. Try RubyGems 2.0 https://coderwall.com/p/html5w Michal Papis demonstrates how you can give the forthcoming RubyGems 2.0 a spin using RVM. Your Objects, the Unix Way: Applying the Unix Philosophy to Object-Oriented Design http://blog.codeclimate.com/blog/2012/11/28/your-objects-... Everything You Ever Wanted to Know About Constant Lookup in Ruby http://cirw.in/blog/constant-lookup.html Simple Authorization in Ruby On Rails Apps http://www.elabs.se/blog/52-an-elegant-authorization-syst... Improve Your Ruby Workflow by Integrating vim, tmux and pry http://velvetpulse.com/2012/11/19/improve-your-ruby-workf... Watching and Listening ---------------------- Rapid Programming Language Prototypes with Ruby and Racc http://confreaks.com/videos/1319-rubyconf2012-rapid-progr... At RubyConf 2012, Tom Lee demonstrated how you can use Racc, a LALR(1) parser generator that emits Ruby code from a grammar file, in the process of creating a simple programming language of your own. A Tour Into An Oddity With Ruby's Struct Class http://www.youtube.com/watch?v=9IX1NfwQP1s In which I look into why Struct.new(:foo?).new(true).foo? doesn't work, even though the Struct-produced class and its instances are valid. I dive into the MRI source code a bit to get to the bottom of things. 12 minutes in all. RubyTapas 027: Macros and Modules http://devblog.avdi.org/2012/11/27/rubytapas-027-macros-a... Avdi Grimm's latest Ruby screencast for non-subscribers to his Ruby video site. A Rails 4.0 Roundup in 3 Videos http://xterm.it/rails-4-roundup/ A summary and links to three Rails 4 related videos (all linked in RW before) by Marco Campana. A handy catch up if you didn't already. The Ruby Rogues Discuss Rails 4 with Aaron 'tenderlove' Patterson http://rubyrogues.com/081-rr-rails-4-with-aaron-patterson/ Libraries and Code ------------------ Introducing the Rails API Project: Rails for API-only Applications http://blog.steveklabnik.com/posts/2012-11-22-introducing... A set of tools to use Rails for building APIs for both heavy Javascript applications as well as non-Web API clients. This isn't entirely new but the project has now become more formally established. Zuck: A Little Helper to Access Facebook's Advertising API https://github.com/moviepilot/zuck An early, prototype-stage gem but you may still find it useful.

Tanner [Salt Lake City, Utah] http://jobs.rubyinside.com/a/jbb/job-details/760254 Last but not least.. -------------------- Come Speak at O'Reilly Fluent 2013 http://fluentconf.com/fluent2013 OK, it's slightly offtopic but I'm the co-chair for O'Reilly's JavaScript, HTML5 and browser technology event and I know many Rubyists are also involved in these areas.
