Howerrow

In 1991 my wife and I passed Dillon, Colorado on I70 on the last leg of a car-camping vacation. A few months later we picked a male kitten from a litter on the basis of it climbing up and into a filled watering can and having a quick dip. Dillon is now 15 and seems to have responded to the challenge of the young (and I just typed "jung" and had to fix it) upstart male cats nearing their third birthday: Magic and Moon Pie.

I accidently taught Dillon to say a passable approximation of "hello." My wife and daughter have both started to notice it (and reinforce Dillon) and if the rate gets up much higher I should consider teaching Dillon a discriminable stimulus to use as a prompt. Maybe an innocuous sound, like a certain kind of cough. But that Dillon can say "Howerrow" is a fun start.

My wife was skeptical until Dillon came to my side of the bed as we were reading one night and meyowed several times with no reaction from us. Then he said "howerrow" and I said "Hello Dillon! Come up and let me pet you" while patting the bed invitingly. He jumped up instantly and got a lot of cuddles. At about this time my wife and I both realized what had happened and how Dillon is training me to reward him for saying hello. My reward is of course hearing human language coming out of a cat's mouth. But this was completely accidently until a couple weeks ago when we became conscious of it and the rate seemed to go up. We'll see where this goes. NO, it will not go to Letterman, as Dillon isn't stupid!

Immortal Source Code

The ISA of a VM (i.e. it's bytecode set and the semantic definition of all the bytecodes) can change and hypothetically all existing higher level ("source") code can be moved forward to the new ISA/VM combination with a well understood compiler bootstrapping process. So not only does a VM insulate source code collections from necessary hardware and low level ISA evolution, it supports evolution of the higher level ISA of the VM itself. An example of this that has been going on for years is concurrent evolution of the Java virtual machine and maintenance of backward compatibilty, providing "immortal source code." And for where the GPL is involved one gets "immortal open source code." I wonder if Forest (Earl) Gilmore, Don Parce, and Robert (Bob) Nichols shared a vision of this possible future when they launched Business Application Systems in 1978 to create BASPort? (BASPort was a portable operating system: Think Java on top of an extremely simple OS kernel and *everything* but the kernel itself and the virtual machine being in the portable language.)
