Should I learn MacRuby or RubyCocoa
macos, macruby, ruby, ruby-cocoa
Solution
Go with MacRuby. It's the future :)
It's newer, way faster, and much better integrated. HotCocoa is awesome as well.
MacRuby is a Ruby VM implemented on top of Apple Technologies as opposed to a bridge like RubyCocoa. A Ruby String for example is an NSString by nature, instead of being bridged by the runtime. It's a much cleaner, faster and more solid approach. It's also developed and sponsored by Apple, which means it could become part of OS X at some point.

Problem
I am wanting to learn mac development with ruby but I'm not sure which one to go at. RubyCocoa has been around longer but I think MacRuby will beat it out in the long run.. Any suggestions??
