This Week's Ruby News - Issue 90
Ruby Weekly - A Weekly Ruby Newsletter Issue #90 - April 26, 2012 From the Editor's Desk.. ------------------------ Welcome to issue 90! Be warned, this is a Rails-heavy issue, probably because RailsConf was this week. Still, lots of great Ruby stuff to check out, so let's get to it :-) Headlines --------- Ruby 1.9.3-p194 Released http://www.ruby-lang.org/en/news/2012/04/20/ruby-1-9-3-p1... A small version bump for Ruby 1.9.3 which includes a security fix for RubyGems (and therefore an updated version) along with oodles of minor tweaks and fixes. MRuby: A Lightweight Ruby Implementation by Matz https://github.com/mruby/mruby It's been in the making for a while (remember RiteVM?) but this week Matz's new 'lightweight' Ruby implementation, mruby, spread around the Rubysphere like wildfire. The key goal is to produce an embeddable Ruby implementation that has a smaller footprint than MRI. MobiRuby: A Forthcoming Ruby Toolkit for Building iOS Apps http://mobiruby.org/ From our sponsor ---------------- Learn Rails 3.2 with Michael Hartl's (Just Updated!) Rails Tutorial http://zfer.us/EKm97 This is a great way to learn Rails. You can read the book online for free but it comes into its own with his PDF book and over 15 hours of screencasts showing you how to work with Rails 3.2 and build apps start to finish. Code 'rubyinside25' gets you 25% off till the end of April. Reading ------- Extending Ruby with Ruby http://speakerdeck.com/u/michaelfairley/p/extending-ruby-... Some beautiful, code-driven slides by Michael Fairley that dig into adding new features to Ruby by using Ruby itself. To do this, he takes a feature from each of Haskell, Python, and Scala and adds it to Ruby. The slides are complete with speaker notes so it's easy to follow along. Read Ruby 1.9: The Online Ruby Book http://ruby.runpaint.org/ Not new at all but the site recently went down and I lamented the loss of one of my favorite online Ruby references. Finally it's back online, so it's time to let people who haven't seen it before enjoy its greatness :-) On mruby and MobiRuby http://matt.aimonetti.net/posts/2012/04/20/mruby-and-mobi... Matt Aimonetti, a key contributor to MacRuby, riffs on the possibilities opened up by mruby and MobiRuby (both above) while suggesting that it'll take a lot for Ruby to be considered a logical choice for iOS development, even by existing Rubyists. 10 Things You Didn't Know Rails Could Do http://speakerdeck.com/u/jeg2/p/10-things-you-didnt-know-... The slide deck from a RailsConf presentation given by Ruby demigod James Edward Gray II. In a mere 234 (!) slides, he digs into a lot of interesting Rails crevices. Lots of short examples to enjoy. The Asset Pipeline for Dummies http://coderberry.me/blog/2012/04/24/asset-pipeline-for-d... Eric Berry explains the Rails asset pipeline from the absolute basics up. Getting Started With mruby http://matt.aimonetti.net/posts/2012/04/25/getting-starte... Matt Aimonetti is a real fan of mruby and shows it off by explaining its purpose, comparing it to Lua, and then by building a barebones C app that calls mruby to run a single line of Ruby code. Make the Web Fast(er): One Rails App at a Time http://www.igvita.com/slides/2012/railsconf-making-the-we... A great slide deck by Ilya Grigorik about the role that page loading speed has to play in Web applications. It's not particularly Rails focused at all but it covers key things to be aware of. MySQL Query Comments in Rails with Marginalia http://37signals.com/svn/posts/3130-mini-tech-note-mysql-... Noah Lorang of 37signals talks about marginalia, a new gem that adds extra comments to Rails' logs which can help in the debugging and performance monitoring process. Building an iOS Photo-sharing and Geolocation Mobile Client and API https://devcenter.heroku.com/articles/ios-photo-sharing-g... A fine tutorial in the Heroku Development Center about building a photo sharing service with a native iOS client and Rails backend. All deployed on Heroku, naturally :-) Rails Tutorial for Devise with CanCan and Twitter Bootstrap http://railsapps.github.com/tutorial-rails-bootstrap-devi... Daniel Kehoe is known for his detailed Rails tutorials and this time he demonstrates how to create a Rails 3.2 application using Devise with CanCan and Twitter Bootstrap, from start to finish. Hitchhiker's Guide to Metaprogramming: Class/Module Hooks http://rubysource.com/hitchhikers-guide-to-metaprogrammin... Watching and Listening ---------------------- Matz Talks About mruby and Its Possibilities http://www.youtube.com/watch?v=n7XRYWclYDY Back in November 2011, Matz gave a short (9 minutes!) but sweet talk about mruby, what it's about, and where it's headed. The Ruby5 RailsConf 2012 Podcast http://ruby5.envylabs.com/episodes/270-episode-266-april-... The Ruby5 podcast dedicated an entire episode to RailsConf 2012, summarizing DHH's keynote and talking about some of the other things going on, all in a mere 9 minutes. RailsCasts on Queue Classic http://railscasts.com/episodes/344-queue-classic The PostgreSQL database system can act as a worker queue for Rails apps replacing the need for a separate process to manage background jobs. Ryan Bates shows us how with the 'queue_classic' gem. Rails Sustainable Productivity with Xavier Shay http://confreaks.com/videos/815-larubyconf2012-rails-sust... At the LA Ruby Conference, Xavier Shay gave a talk about testing, data modelling, code organisation, build systems, and more, while suggesting many Rails Best Practices go against the building of solid and robust applications. 30 minutes long and well recorded/produced. Libraries and Code ------------------ rails-api: Rails for API Applications http://blog.wyeworks.com/2012/4/20/rails-for-api-applicat... Several popular Rubyists have built rails-api, a plugin that can trim down usually unnecessary Rails features for API-only apps. They are particularly keen for people to try it out and send in their performance results so that it might be added directly to Rails core in future. T: A Command-Line Power Tool for Twitter (written in Ruby) http://sferik.github.com/t/ Allowy: Another Simple Authorization DSL for Ruby (and Rails) https://github.com/dnagir/allowy How DHH Has Tidied The Rails routes.rb File on BaseCamp Next https://gist.github.com/2492118 mongoid-minitest: Minitest Matchers for Mongoid https://github.com/frodsan/mongoid-minitest Jobs ---- Developer Advocate/Spokesperson/Evangelist at New Relic [San Francisco] http://jobs.rubyinside.com/a/jbb/job-details/674522 New Relic is the emerging standard for application performance management and wildly popular in the Ruby world.
