Deploy a Rails 3, Sqlite3 application in Tomcat using JRuby
In this tutorial, I described the steps I did to deploy a simple Rails 3 application to Tomcat using JRuby. In addition, I show a way to make your Rails 3 application run side-by-side with a JRuby-based version.

I also included the problems I encountered along the way and how to solve them.

ZooKeeper ruby client update
I just fixed up the Zookeeper ruby client. Now C and Jruby have the same interface and watches work in MRI. It's still not completely specced and hasn't been used in production, but it's looking pretty promising. Zookeeper sure lets you do a lot of cool stuff that would otherwise be really hard in a cluster.

Install any Java library as a JRuby gem
Charles Nutter: "... a prototype Maven server that looks and feels like a RubyGems source. By setting this server as a source (or passing it to the gem command), any Java library in the world is installable as a gem. Let me repeat that: ANY Java library in the world, installable as a gem. This means you can also use Maven artifacts as dependencies in regular Ruby gems, and it additionally means we won't have to re-release jar files into their own duplicate gems on the standard repositories. It's very exciting, and we hope to have it ready for JRuby 1.5." You can get it here: maven_gem at github

QR (de)Coding
Encoding QR Codes with Ruby is a solved problem, but decoding is another story. There are several Java libraries that provide decoding functionality though, so wrapping one of them with JRuby is likely a good idea.

Using Duby + JRuby for Fast Prototyping of Fast VST plugins
I've been working on JRuby/Duby interop to implement VST audio plugins. The first working plugin is a LP/HP filter (with cutoff and resonance). JRuby is used for declarative stuff, while Duby is used for computation intensive stuff. The combination gives an interesting Ruby-tasting audio programming experience.

[ANN] Do YOU want to learn JRuby using Google Wave?
A tool such as Google Wave enables the students to collaborate together in an online environment. Wave replaces the need for multiple services such as a Wiki to post work, Google Docs to collaborate on documents, email to communicate asynchronously, and instant messaging services to communicate synchronously.

At RubyLearning we have been teaching the Ruby programming language, related libraries, and frameworks for the past three years, using traditional tools. With the advent of Google Wave, we wanted to try and understand ourselves the effectiveness of using Google Wave as a teaching tool. Interested? Let's collaborate.

Announcing the First Ever JRubyConf!
It’s our extreme pleasure to announce the first annual JRubyConf, to take place Sunday, November 22nd, immediately following RubyConf 2009! We’ve been working on putting this together for a little while now, and it’s finally time to share.

The JRuby project has been making incredible progress and gaining popularity; at the same time, the community has been growing like crazy. At this stage, we think JRuby definitely needs a conference of its own. The roster will be highly technical, cutting edge, and will feature JRuby experts from all over the globe. More details in the blog post! Keep an eye on the conference website for future updates!

Updated Ruby Switcher: Working With Multiple Ruby Versions Has Never Been This Easy
The Ruby Switcher is a super-lightweight tool for quickly switching between Ruby versions. You can easily experiment with Ruby 1.9 to try out a gem or two, and if you run into issues, you can safely retreat back to 1.8.x (after you report the Ruby 1.9 problems to the gem's maintainers, of course). The latest version includes single-line commands that install the various Ruby versions for you. Wanna try out Ruby 1.9.1? Just type install_ruby_191, and the Ruby Switcher handles the rest. The Ruby Switcher gives you shell-specific Ruby versions: while one terminal window is testing out a gem or app in Ruby 1.9, you can have another terminal performing the same tests with Ruby 1.8.7 (or JRuby, or Ruby 1.8.6, or REE, or Leopard Ruby, etc.). When switching between Ruby versions is this seamless, there’s no reason not to experiment.
