In what is partially a response to my earlier post, Bob Warfield asks:

Sun has “cultivated and vigorously supported” Ruby.  When will we read something similar to either announcement from Microsoft, instead of reading things like they’re going to quit shipping the JVM at the end of the year?

At least this one is easy. Microsoft announced Iron Ruby back in April.

But Iron Ruby runs on .NET. Right, so what does Sun’s Ruby run on? The JVM, of course.

By the way, I cannot think of any good reason why Microsoft should revive its JVM – withdrawn, you recall, at Sun’s insistence. Microsoft’s JVM was horribly out-of-date anyway; and there are several perfectly good JVMs that run fine on Windows.
