Rails in .Net
John Lam just announced publicly that IronRuby is able to run Rails. It doesn’t run it fast at this point, but it is compatible. Speed and performance will be drastically improved as the project develops. This is a good thing for .Net to be able run Rails; it’s only going to make the .Net platform richer with its available languages.
When I was at RailsConf last May Microsoft was almost completely ignored in the normal part of the conference. I think there was a single session related to installing and deploying on the Microsoft platform.
In the hallways Scott Hanselman and Chris Sells got some good hallway conversations going with Martin Fowler and other ThoughtWorks people. This year and even more in the following year it will be much harder to ignore the Microsoft implementation of the language.
