Benjamin Curtis and Andreas Viklund have launched the Ruby on Rails Plugins Directory. Benjamin describes the site as a place, "where you can find all Rails plugins you could possibly want. I'm always on the hunt for new plugins to add to the directory, so you can be lazy and just come here to find the latest and greatest contributions from the Rails community. There are RSS feeds to keep you up to date, and a recently added category if you're into the old-school way of getting updates."
You can even use the Rails Plugin Directory from the command line plugin script in your Rails application by executing the following:
script/plugin discover http://www.agilewebdevelopment.com/plugins/scrape

Wilco Bauwer has been working for the past few months on a Ruby interpreter for the .NET CLR, a project similar to IronPython. So far only some of the basics of the language are implemented, and current work includes incremental progress on OO features, Mixins, CLR integration, dynanamic methods, and Ruby file includes.
Wilco ids documenting the challenges in a paper for a college assignment, and will publish the paper once it is complete.

Ezra Zygmuntowicz has announced the alpha release of a framework to help you manage long running background tasks in Ruby on Rails applications. Ezra describes it as follows:
BackgrounDRb is a small framework for divorcing long running tasks from Rails request/response cycle. With HTTP it is usually not a very good idea to keep a request waiting for a response for long running actions.
BackgrounDRb also allows for status updates that in combination with ajax can render live progress bars in the browser while the background worker task gets completed. The MiddleMan can also be used as a cache. You can store rendered templates or compute intensive results in the MiddleMan for use later.

Jason King and Josh Susser had an interesting conversation about how to use ActiveRecord to achieve Polymorphic, many-to-many, self-referential associations on the Ruby on Rails mailing list. Jason describes his problem domain as having a:
Container which can contain one or more Element. An Element is a polymorph of either a Container or a Chunk. An Element can exist in one or more Containers. I use a table called ownerships as the join between Containers and Element.
Josh Susser, author of the has_many :through blog, attempts a solution. He describes his trick, "You have to disambiguate the two different associations to containers—one way is as your container, and the other is as an element. That means you need different names for those relationship. I chose "owner" to indicate an element's container from the element's perspective. You also have to use a different name for the two kinds of ownerships, containing and contained."
Read on for the final coded solution.

Thomas Bayes, 1702-1761Surendra Singhi of Calcutta, India, has released an extremely useful text classification plugin for Ruby on Rails. Using a Bayesian classifier you can flag comments, email, articles—whatever chunks of text you'd like to keep a handle on so that when you encounter more like it, you can do something automatically with it. Pick some categories, such as 'spam' or 'not spam', 'good' or 'evil', or even 'ironic' and 'irony-free', classify some existing text or data, and then use the method to predict the classification of an unknown text.
Read more for a summary of its usage.
