And also as PDF on the SlideShare.net:
I was talking about proof of concept port of Katello to JRuby. I had several issues with rubygem slow loading, bundler and rvm. The actual port was pretty smooth and I was giving several tips for JRuby porting, in particular for Ruby on Rails applications. At the end of the talk, I did short introduction to SystemTap and it’s integration with Ruby as well as bundler_ext extension.
The session was recorded, expect the video to be published hopefully soon.
