I recently launched Tork for efficient continuous Ruby/Rails/Cucumber testing.
Since MetaWhere is not compatible with Rails 3.1/3.2 and we are now directed to use Squeel instead, and I needed to use CanCan MetaWhere depending functionality, I made this gist that replaces MetaWhere with Squeel in CanCan 1.6.7 . Now one can write:

can :manage, User, :permissions.outer => {:type.matches => 'Manage%'}}

This fixes several issues. Happy coding!
I just launched some groovy thing and yada yada.
Heroku offers Ruby 1.9.2 as a default with its newest stack. But did you know you can use Ruby 1.9.3 (Ruby's current recommended stable release)? Here's how to set up an app with Rails 3.2 and Ruby 1.9.3 on Heroku. See Deploying Rails 3.2 with Ruby 1.9.3 on Heroku.

I just wrote a small how-to about upgrading to Rails 3.2.0 from Rails 3.1.3. It's not so hard as I thought it'd be and new Rails bring us some cool new features. Enjoy :)
Rail's engines can be a bit of a pain to write tests for. Since they don't run in the full Rails stack it requires a bit of pain to setup anything but the most basic testing. test_engine solves this problem by making it almost as easy to write tests in your engine as it is to write tests in your Rails app. If you have been holding out on testing your engines because you don't know a good way to implement it maybe this is your ticket to get back on track.
I wrote a post about how to insert more Disqus comments box in a single page using Ruby on Rails, an iframe and jQuery to dinamically load the comments box.

Factual has released an open source officially supported Ruby driver for their data platform. It supports all the main features of their growing data ecosystem, including geolocation queries against their curated Places data.
Have you ever needed multiple validations on one field (I bet you did!) but didn't like multiple error messages showing up at the same time? Read my blog post to see how you can prevent it.
If you have to process a large amount of external http requests bound by database access, maybe the em-resque gem we've just created could be useful for you. You can get more information in related article about it.

500 participants have already signed up for this, the first round of the FREE Online Course: Programming for the Web with Ruby It has gotten the attention of some people we look up to, like Antonio Cangiano and Matt Almonetti and Steve Klabnik, among others. A 10 day course, with the first 4 days already open, awaiting the opening day. We had to open those days, because our participants are just too excited, and needed to have something while we await the start date!

There's been a bit of misrepresentation of DCI in recent articles. I try to amend that by describing The Right Way To Code DCI in Ruby. I would love to hear feedback.

The view layer in web app frameworks is broken, and here's why.
No matter what kind of programming you are doing these days you probably heard a lot about Smalltalk. And there is a reason for that. Its influence on what we are doing and using right now is hard to overestimate. Refactoring, XP, TDD, many VM technologies came from the Smalltalk community. more

I just launched tconsole, a testing console for Rails with mintiest. It speeds up test performance by preloading your Rails environment (similar to how Spork does), but also helps out with testing workflow by providing a pretty simple syntax for testing single test files or even specific tests.

Check out the README on GitHub for more info!
Typed Fields in Ruby  victorsavkin.com
One of a few things I missed when I switched from ActiveRecord to ActiveModel is all type conversions AR takes care of. You just pass a bunch of strings and it knows what to do with them. TypedFields gem does similar kind if stuff but without tying it to ActiveRecord.

cheatorious: "Being victorious through a means so amazing it cannot possibly be achieved without cheating." (Urban Dictionary)

https://github.com/lfcipriani/cheatorious

Cheatsheets are very good to start learning or keep knowledge of some language or tool, but very often you just don't have the proper cheatsheet at hand when you need to remember that cryptic keyboard shortcut. Furthermore, wouldn't be nice to keep or create your own cheatsheets in a neat ruby DSL? Wouldn't be great if you have easy access to them, such as via command-line interface?
I've refactored my pws gem and now it's fun to use :)

I have just created a small demo app called Bugs Bunny: a Unicorn served Sinatra application which uses Bunny (a Ruby AMQP 0.9.1 client) to broadcast messages to every Unicorn worker. It requires an AMQP message server, such as RabbitMQ, in order to publish and receive messages. Clone the repository and run it yourself at Github.

WebSockets, SPDY, SSL, and persistent connections are in, except that our infrastructure can't support most of these use cases. To enable the modern, real-time web, we need to drag our 'back office' architectures into this century.
