Victor Igumnov has put together a simple walkthrough of how to package a Rails application into a single WAR file to run on a Tomcat server using JRuby, a pure Ruby PostgreSQL library (no ActiveRecord-JDBC needed!), and GoldSpike (JRuby addon that provides rake tasks to make WAR files). This is useful knowledge for anyone who might be forced into deploying Rails apps in an enterprise type system where Tomcat may be the only viable deployment option.

Joyent Slingshot allows developers to deploy Rails applications that work the same online and offline (with synchronization) and with drag into and out of the application just like a standard desktop application. Check its two-minutes tutorial to get a feel of how you can make it work.

Erlectricity is a very early stage library in a "pre-release" stage that acts as an interoperability bridge between Ruby and Erlang processes. Scott Fleckenstein is the developer, and he is going to continue blogging about Erlectricity's development, and Ruby / Erlang interoperability on his blog. While this topic isn't quite mainstream yet, many Ruby developers have become interested in Erlang lately and Ruby / Erlang interoperability and co-operation is likely to become a big topic in the Ruby community towards the end of the year.

Slideshare is like the YouTube or Scribd of presentations and slideshows and it features a few good Ruby and Rails related slideshows that are worth flicking through. This post links to some of the best:

I've stumbled across several great snippets of Ruby code on the Web in the past few weeks, and rather than bore you with a post on each one, here's a whole collection at once:
