RoR enthusiast, that's the main reason why I'm here. Besides Ruby and Rails, I know Perl pretty well. I'm also interested in Python, Scala and Lisp (resp. Clojure).
I'm also Linux enthusiast and I like Ubuntu in particular, I use it both on my notebook and desktop. I have used Red Hat, CentOS, Mandriva, SuSe and Gentoo distributions as well.
