Confreaks just released a Ruby/JRuby GPU presentation of mine from Mountain West Ruby Conference 2011 in Salt Lake City, Utah. Slightly stale, but all still very relevant to HPC today!

Over the past year I’ve put out a few working demos of how to develop full 3D, OpenGL-based OSX applications using Ruby. Most of the comments I’ve received have been positive, but I think the high learning overhead has been the prime limiting factor in addoption. I also decided to focus exclusively on Mac OS X, further limiting the potential audience.
I’m pleasing to learn that Martin “monkstone” Prout has successfully run the code contained within my Starfield.app–basically a folder of code on a OS X system that looks and behaves like an .exe does Windows–on a Kubuntu Linux system. I haven’t personally tried to replicate this myself due to a lack of time, but you can read how monkstone did it on his blog.
