Last year, Apple released MacRuby, an open source Ruby implementation written on top of the Objective-C runtime. Writing native MacOSX applications in Ruby without having to pay the cost of using a bridge is now a reality. This is an important milestone for Ruby, Apple and the Ruby community.Matt Aimonetti will explain the implementation, show how to build desktop applications with MacRuby & HotCocoa, and discuss why Ruby developers should add this new tool to their utility belt. Matt will also talk about the future of MacRuby.
