Gorn,
I just wanted to express to you how impressed I have been, over the years, with both the depth and the breadth of your technical expertise regarding desktop computers. I was gratified by your comments about me and databases, but this interchange has definitely been a two way street.
It doesn't matter whether the subject is hardware repair, or operating system internals, or how Delphi works, or Wordpad and doc files, or the essentials of OOP, you've been right there with the requisite knowledge to make sense of it all, for me or other people on the various forums where we interact.
I don't mean to limit you to desktop stuff. I imagine you've dealt with servers, the web, the cloud, and like that. But desktop expertise is where your background is strongest compared to mine. I briefly tried to learn assembler for the 8086 after buying my first computer. But it was a struggle, and it was boring after having done the same thing for the early machines. It wasn't until I got Turbo Pascal that I could actually program my own machine.
And, in almost every way, I've been "just a user" ever since I bought into windows. Not so you. Kudos.
