CoffeeScript, a Little Language with a Pure Ruby Compiler
CoffeeScript is a little language with a Ruby-esque syntax that compiles into the good parts of JavaScript. The compiler uses vanilla Ruby classes for the lexer and code generation, and Racc for the parser. If you’ve ever wanted to use Ruby to experiment with a little language, it’s a good example to take a peek at.
has_scope and responders released
We, at Plataformatec, just released two new open source tools: has_scope and responders, both extracted from Inherited Resources. has_scope allows you to quickly map controller parameters to named_scopes and responders is a repository of Rails 3 responders, which can already be used within Inherited Resources. As conclusion of this refactoring, Inherited Resources finally reaches 1.0. Read the blog post to catch up all changes.
Generating Thousands of PDFs on EC2 with Ruby
For about two months, we’ve been working on a static website that exposes the results of complicated economics model to non-economists. We decided to make the site static because of the overhead involved in computing the results and the proprietary nature of the model. We would simply pre-generate the output for all valid permutations of the inputs. However, on a single machine, we found it would take 30 hours of uninterrupted processing! Clearly, this was a job for “the cloud”.
Active Record Enumerations (single db integer column) - plugin
I just added my first plugin ar_enumerations which allows to use “enumeration” field in your AR models. This plugin was at least useful for me, because it saved me from a lot of “has_many” tables and data stored to single integer column. Also I’m providing the sample application where you could see plugin in action. I hope this plugin will be useful for you too.

A hands on look at the API, and implementation of Ruby WebSocket server and clients.
