Linux has been my main OS since 1992. Kernel 0.97, i think. I've been a Unix guru since 1982.

There were no Unix manuals to speak of in 1982. Just source code. That has changed, and we still have source. In Winders, you struggle figure things out, and then it changes, or you keep running into bugs. In Linux, once you figure it out, it works forever.

My 1987 Mac II died in 1997 (only 20 years). I transplanted the brain (that's the hard disk, not the CPU as you might expect) into a newer 68000 box last year. I'll do that again soon, as this one has died too. I may have to run a Mac emulator soon.

You could learn everything eventually, if it weren't for all the new stuff coming out, uhm, every day. And it's not like, hey i've got this filter that converts Mac newlines to Unix. It's more like, hey, i've got this new app that lets you create and edit animation over 3D models, and the next day it's, hey i've got this new app that lets you edit musical score, and the next day it's, hey i've got this new app that converts text to speech. With all this new stuff coming out, who has time to build new stuff?

It's been a wild ride.
