At Codegram we are hosting a hackfest for
Rubinius International Day (hashtag #rbxday) for Barcelona and surroundings, this Friday August 5th, starting at 3 pm. The goal is to learn about this awesome Ruby implementation, run our already working Ruby apps and gems on it and discover bugs, performance issues and other stuff. You can then file bug and performance reports and help improve
Rubinius, and maybe contribute a patch!
