I gave a talk in January 2007 for my Language Processors and Compiler Construction course at RIT on Rockit, a parser generator library for Ruby. I touched on versions 0.3.8 and 0.7.2, which are GLR and PEG driven, respectively.
Multitouch: FTIR
In my last term at RIT, I took a course titled Innovation and Invention with Dr. Jon Schull. It was rather experimental, with a breakneck pace and minimal organization that was both highly productive and rewarding. It has continued to flourish, and has significant overlap with the new Collaboratorium at RIT.
As part of this course, I worked on a multitouch display (see my project log for the multitouch table). Matthew Kampschmidt and I gave a talk that introduces multitouch technology and applications, as well as the fundamentals behind FTIR (Frustrated Total Internal Reflection).
Introduction to Ruby
I gave a talk at our second Rochester on Rails meetup in January 2006 that gives a brief and basic introduction to the syntax of Ruby 1.8, along with a few nice language features.
Introduction to Rails 1.13
I gave a talk at our second Rochester on Rails meetup in January 2006 that is an entry-level introduction to Rails (circa 1.13) . It covers the history, reasons you may use it in a project, and basic architecture of Rails.
