A tired, not yet retired engineer
I have been using computers since the times of Apple][ ...
That was some ten years before Linus released the very first Linux kernel.
Sadly that doesn't make my computer knowledge better ;-) I've seen a vast diversity of PC-grade machines and software - and that might be one reason; it has simply been too many.

- jumped ship on MS OS'es just a year ago - Still using "7" at work though.
- been dabbling with Linux/bash for a long time, now actually running one; Ubuntu.
