JRuby is a way into the enterprise for Rails.

…. and believe me the enterprise needs Ruby and Rails and well yes Oracle too ….

Glad to see Sun and Oracle embrace Rails and Ruby so passionately in recent months.

Check out Oracle Mix.

Ruby, my favourite programming language is taking over the world. I have proof:

1. JRuby reached V1 this year
2. I can run Ruby on Rails apps on GlassFish
3. IronRuby runs in a browser via Silverlight (meaning .NET does Ruby)
4. Ruby is pioneering Behavior Driven Development with RSpec and RBehave
5. …..and we have BuildR - a Java build tool written in Ruby

Ruby promotes Language Oriented Programming - we need domain specific languages to do the task at hand not Java or C# syntax to do any job.

Plugins are one of the reasons I really digg Rails. Essentially plugins let me do stuff without re-inventing the wheel. The fewer lines of code I write, the happier I am. I’ve always had a fascination with TreeMaps and could see the idea being useful in a few projects. With the acts_as_treemap plugin I can now immediately implement a TreeMap. Rob Orsini has posted a tutorial on getting up and running.
If you happen to be wondering what a TreeMap is and how it could possibly be useful as an information visualization tool: A picture is worth a thousand words.
