just to add somting, ruby its self is a programming language where as Ruby on Rails (RoR or just Rails) is the web based scripting ruby. Still doesnt change the fact that they are both very different (javascript and ruby).
That list needs to seperate languages into there specific catagorys as compairing a language like C to javascript is mad and totally invalid.
