Virtual Machine bits
Here's some virtual machine bits found floating in the blogosphere today.

First, James Robertson correctly states that the JVM needs to be unfrozen, so that dynamic language performance could be decent. I agree, but I would be more than slightly surprised if Sun ever did this.

At the other end of the spectrum, Patrick Logan picked up and expanded upon my post yesterday questioning whether the days of the VM approach are coming to an end (this of course will make Microsoft unhappy because they just got here). Patrick points out old (but not necessarily well known) results that allow natively targetted languages to achieve all of the benefits of VM's. At least the VM benefits that I listed.

And earlier in the day, there was a confluence of these two fine gentleman over the question of 64 bits for dynamic languages. Anything that makes it go faster is good. Here's looking at those G5 Powerbooks and Opteron desktops when they arrive.

Ted Leung posted about VM's the other day, and Patrick Logan raised some interesting questions. This all piqued my interest, so I asked:

One question I'd have about the stuff Patrick points to - does it allow for updating installed software on the fly? It doesn't sound like it does, and to me, at least, that's a full stop. On my site, I'm doing live server updates all the time - it's just the way I work.

Ted responded today with some details on a Scheme project, and some information on what people can do with mod lisp. Looks like we need a mod-smalltalk module.
