Updated: 2010-08-31 21:52:24So, you've gotten your shiny new Mac and you want to get right into Ruby programming, where how do you install it? The first thing you should know is that it's already installed. OS X 10.6 "Snow Leopard" comes with both Ruby 1.8.7 and Ruby on Rails 2.3.5 installed. But there are a lot of reasons why you'd want to install your own with RVM, access to Ruby 1.9.2 being the most obvious....Read Full PostBDDCasts on Rails3 and Cucumber

Updated: 2010-08-30 00:21:27Rails 3.0 has been underway for a good two years, so it’s with immense pleasure that we can declare it’s finally here. We’ve brought the work of more than 1,600 contributors together to make everything better, faster, cleaner, and more beautiful.David Heinemeier Hansson DHH rings the bell and announces that Rails 3.0 (final) has been released after two years of determined effort by the Rails core team (and, significantly, Merb team members, since Rails 3.0 is heavily influenced by the ). Grab it now with gem install rails --version 3.0.0 or, if you're in no rush, Rails 3.0.1 might come along within a week or two. The Videos DHH gives a quick roundup of some of Rails 3's new features but like Emma Watson's head PhotoShopped onto yet another naked body, it's nothing you haven't seen before. If you're really fresh to Rails 3.0, though, Gregg does an admirable job of boiling everything down into a digestible format with his (free!) Dive Into Rails 3.0 screencast series: Getting Started and Action Dispatch Bundler and Action Mailer <a href="http://rubyonrails.org/screencasts/rails3/active-relation-active-model"Active Relation and Active Model Cross-site scripting and Unobtrusive JS The New Action Controller Ryan Bates has also produced a fistful of his typically succinct but precise RailsCasts videos on a wide array of Rails 3.0 topics. Ryan always focuses on code and practicalities so these are a good place to start if you want to follow along and do some coding yourself: Upgrading to Rails 3.0: Part 1, Part 2 and Part 3 Routing in Rails 3 Active Record Queries in Rails 3 Advanced Queries in Rails 3 Controllers in Rails 3 Rack in Rails 3 Subdomains in Rails 3 Active Model Generators in Rails 3 Making Generators in Rails 3 Validations in Rails 3 ERB Blocks in Rails 3 Action Mailer in Rails 3 XSS Protection in Rails 3 Bundler If you don't like videos, still follow the links, because there are links to the ASCIIcasts regular HTML versions of the Railscasts videos. These are regular blog posts that you can follow at your own pace. Or some books Michael Hartl's Rails Tutorial book is the #1 (and only, in my opinion) place to start when it comes to books about learning Rails 3.0. Not only is it available to read for free online, but you can buy a well formatted PDF too. It's an amazing piece of work and, unusually, walks you through building a Rails app from start to finish with testing. If you want to just read one book/site and feel like a Rails 3.0 master by the end of it, pick RailsTutorial.org. If you speak German, though, check out this "Ruby on Rails 3" book by Michael Voigt and Stefan Tennigkeit. It's one of the first Rails 3.0 specific books to hit the presses. Or just dive into some code If you want to just "get started" and check out a working Rails 3.0 application, try Daniel Kehoe's Rails3-Subdomain-Devise app. It's a basic Rails 3.0 app that demonstrates using the Devise authentication system, as well as custom subdomain access. Not just that, but Daniel has put together a walkthrough of how the app works and how it was put together.Ruby Annoyances: Variables Don't Have Type
Updated: 2010-08-27 07:00:26To many programmers new to Ruby and dynamic languages in general, one annoyance or point of confusion is that variables don't have type. Values have type, of course. Strings are Strings, numbers are some type of Numeric, but variables themselves don't have type. What's going on here?...Read Full PostRuby on Rails 3.0 Release Candidate 2

Updated: 2010-08-25 19:49:46It's time to unveil my latest project: Ruby Weekly, a once-weekly e-mail roundup of 10-20 Ruby related links with a few sentences on each. It's had a brief alpha testing period and it's now ready to roll. Click here to subscribe to Ruby Weekly - it's a one click process. It's also ultra simple to unsubscribe if it's not eventually to your taste. As well as featuring links and (very) brief summaries, the weekly e-mail will also occasionally include new event, book, and job announcements and, if something significant is going on in Rubyland, a few paragraphs of editorial. The aim, though, is to keep the e-mail reasonably brief, in a plain format, and, above all, useful.</p There's been a renaissance in e-mail newsletters in the last year or two and it seemed, to me, to be a great way to get programming related news. E-mail is not to everyone's taste (Ruby Inside will be staying as-is!) but if you want to avoid daily distraction and get a summary just once a week, it's an alternative to reloading Twitter or Google Reader every day. The popularity of the Ruby5 podcast proves there's an appetite for Ruby news in different media (and if you prefer audio, check them out). Ruby Weekly goes out once a week on Thursdays, so if you subscribe within the next 16 hours or so, you'll get this Thursday's edition (issue #4).Upgrading to RVM Head
Updated: 2010-08-25 07:00:09RVM is a moving target. It's still under regular development and in order to get the most current versions of Ruby, you'll need to upgrade to the head version of RVM.

Updated: 2010-08-24 22:49:01One of Rack's greatest features is the ability to easily plug in middleware applications. When a request makes its way through Rack to your application, it'll first pass through each of these middleware applications on the way. Middleware apps can be either simple utility apps that do things like log requests, or something more complex like Rack::Lint, which will sanity-check your responses and throw an error if something is wrong....Read Full Posthome_run, Dates and Times 20 to 200 Times Faster

Updated: 2010-08-18 16:27:54Yuki (Yugui) Sonoda has just announced the release of the stable version of Ruby 1.9.2! Ruby 1.9.2 has been released. This is the newest release of Ruby 1.9 series. Ruby 1.9.2 is mostly compatible with 1.9.1, except the following changes: Many new methods New socket API (IPv6 support) New encodings Random class that supports various random number generators Time is reimplemented. There is no longer the year 2038 problem. some regexp enhancements $: no longer includes the current directory. dl is reimplemented on top of libffi. new psych library that wraps libyaml. You can use the library instead of syck. Yuki Sonoda Ruby 1.9.2 passes 99% of RubySpec and, if you haven't already given it a go, offers worthwhile performance increases over Ruby 1.9.1 and significant performance improvements over the 1.8.x series. Intriguingly, Ruby 1.9.2 is only considered to have full, verified support on Debian Linux on 32 bit Intel architectures, with support for OS X 10.5 and 10.6, FreeBSD, Windows, and Solaris considered "best effort." Linux distributions other than Debian are listed in the lower "perhaps" category for support, so running your own tests is more essential than ever before moving to 1.9.2 in production. Installing As always, the source can be picked up from the official sources at ruby-lang.org: http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.2-p0.tar.gz http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.2-p0.tar.bz2 http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.2-p0.zip Or, you can use RVM, which has already been updated to support the release: rvm update --head && rvm reload && rvm install 1.9.2 && rvm 1.9.2 --defaultRuby Programming and Education: A Match Made in Heaven
