Hi all!

We use Ruby (mostly JRuby) for

* Rails
* Thick clients on desktop (SWT)
* Thick clients embedded (SWT)
* Messaging with RabbitMQ
* Database processing with ActiveRecord
* Database schema management with ActiveRecord Migrations
  Also on non-ruby projects!
* SMS applications
* OS Scripting like installation, maintenance, and backup
* System integration: file conversions, mail processing, ftp, etc
* + most anything we need to do :)

...and it is all great fun!
