Ola Bini, Language Geek
Ola Bini works as a language geek for ThoughtWorks in Chicago. He is from Sweden but don't hold that against him. He is one of the JRuby core developers and have been involved in JRuby development since 2006. At one point in time, Ola got tired of all existing programming languages and decided to create his own, called Ioke. He has written a book called Practical JRuby on Rails Projects for APress, talked at numerous conferences, and contributed to a large amount of open source projects.
His main passion lies in implementation languages, working on regular expression engines, trying to figure out how to create good YAML parsers - all with the final goal of taking our understanding of languages to the next level.
