Four of these VM's will hit 1.0 status in the upcoming year and will open up entirely new possibilities for the language — Mac apps via MacRuby, Ruby in the browser via Silverlight, object persistence via Smalltalk VM, and so forth. A detailed look at the past year, the progress of each project, and where the community is heading. It's an exciting time to be a Rubyist."
