The Planetarium

Many of those who attended the first JVM Language Summit last September judged it to be a great success worth repeating.

You can see video of the talks here, like Charlie Nutter's talk on the pain, in all the dirty details, of bringing Ruby to the Java platform. Or John Pampuch on the VM optimisations in HotSpot. Examples from Cliff Click on where languages from Scala to JavaScript can take advantage of optimisations in the JVM. Watch the creator of Maxine describe this Java-VM-in-Java which, amongst other things, optimizes its own JIT with the application its running. Or James Gosling on how the JVM spec was born.

Hope there's another one this year :)
