During 2005 and 2006, we developed a simple Rails application called Codecite that we used to deliver presentations and training materials at our private training classes, and at the No Fluff, Just Stuff Java symposiums. As of 2007, codecite is mothballed. Our new course delivery system for 2007 uses a combination of TiddlyWiki and Prototype to present course materials and lab exercises.
If you are looking for Ruby and Rails samples, we have a more polished set of samples with the book Rails for Java Developers. The sample code is a free download.
We will be moving some of the old codecite material into the Code section of the website. If you are looking for some specific code sample that we have not updated yet, contact us and we will get it to you.
