In Making CI easier to do than not to with Hudson CI and Vagrant, Dr Nic Williams (of EngineYard) presents a walkthrough of setting up a VM-based continuous integration system in order to reliably test your apps across multiple setups:
A few days ago, Burke Libbey, a Winnipeg based Ruby and Rails developer, gave a presentation called Ruby's Object Model: Metaprogramming and Other Magic to the Winnipeg.rb Ruby user group. I though it was interesting enough to embed here.
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.
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.
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:
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!).
EuRuKo is the brand of Europe's principal Ruby conference series and EuRuKo 2010 took place in late May. Why, then, am I posting about it in August? First, I'm a strong supporter of EuRuKo and promised to post a roundup of the event here. Secondly, it turns out it took a while for the videos to all be uploaded ;-) Third, I've taken my time in getting round to it. Nonetheless, there are some amazing presentations you can watch and they're still fewer than three months out of date!
home_run is an implementation of ruby’s Date/DateTime classes in C, with much better performance (20-200x) than the version in the standard library, while being almost completely compatible.
[W]e’ve been having a lot of fun writing a series of small, self-contained web apps .. When we’re building these kinds of applications, which are often meant as low-ceremony apps targeted at a very specific purpose, or as service utilities, a lot of the time we don’t want to go through the hassle associated with a “normal” web app.
Back in June, I did a comparison of Mongoid and MongoMapper, the two best known MongoDB libraries for Ruby. Now, Ben Myles has brought another to the fore: Mongomatic.
Aaron Patterson (of Nokogiri fame) has written a post for the AT&T Interactive blog about writing a code coverage tool with Ruby 1.9:
In April, we wrote about IronRuby hitting 1.0 and Microsoft's "3 years with Ruby [paying] off." It's sad, then, to read today that program manager Jimmy Schementi is leaving Microsoft citing a rapidly decreasing interest in dynamic languages (other than JavaScript) at the software giant.
Yesterday, Lyle Johnson of the FXRuby GUI toolkit project stood aside as the project's maintainer, effectively retiring the project:
If you use Ruby long enough, you will discover the and and or operators. These appear at first glance to be synonyms for && and ||. You will then be tempted to use these English oprators in place of && and ||, for the sake of improved readability. Assuming you yield to that temptation, you will eventually find yourself rudely surprised that and and or don’t behave quite like their symbolic kin...
The Ruby on Rails Tutorial: Learn Rails by Example (a.k.a. railstutorial.org) by Michael Hartl has become a must read for developers learning how to build Rails apps. Michael has put together a great Rails 2.3 tutorial, releasing it all for free online chapter by chapter. Now, Michael's going three steps further:
Mailman is an incoming email processing microframework. You point it at a source of email, such as a POP3 account or a Maildir, and it will execute routes based on the messages that come in.
Due to the nigh insurmountable work of Charles Nutter, Thomas Enebo, Ola Bini and Nick Sieger along with their team we have direct access to Java libraries and thus to a plethora of usefulness. Sometimes I think we forget how lucky we are, the Ruby community, to have such awesome people simplifying our lives, anyway, thats quite enough arse kissing. So, on with the show...
High off Baltimore Pandemic and Yellow Tops, I believe we promised a release candidate shortly after RailsConf. As things usually go in open source, we gorged ourselves on fixes and improvements instead. But all to your benefit. We’ve had 842 commits by 125 authors since the release of the last beta!
It's been a couple of months since the last job round up but the Ruby Inside job board has been hopping! There are 14 live listings to go over today and they're not all in San Francisco. Jobs in Denver and Maryland bring in a bit of interesting variety.
It's out, it's out. Redmine 1.0 is released!
Giles Bowkett (Ruby Inside's top Ruby presenter of 2008) has released a series of free videos called "Secrets of Superstar Programming Productivity" that could interest some of you:
Florian Hanke got in touch to tell me that presentations and photos from the recent Euruko 2010 European Ruby conference are now online.
