Powerful editor, but if you think vi gave you nasty surprises for accidental keystrokes...

I agree it would be a much better use of your time. I don't see "UNIX sysadmin" in your future.

It's a good point, but for me Windows Notepad is incredibly limited. If I can, I install Notepad++. Curiously, I use that on Windows even though I could install vim.

Nope, I'm planning to be one of those dreaded "managers".

I've used Notepad++. It's good. But I didn't need half its features. When I was managing websites, I always used either the tool provided with the CMS (Plone or Drupal), or Notepad. But that's the lovely thing about using a CMS - most of the actual hard coding is done for you. All I was doing was tweaking the html.

Not curious at all

If you were using CMS then you were most likely using xedit for your editor.

This is correct, but sometimes I copied it out of that and into notepad for certain tasks.

CMS = Content Management System I assume, rather than VM/CMS. Web pages to edit and manage web pages.

By contrast, Perl and Python, which are interpreted and have automatic garbage collection, never crash due to dangling or overwritten pointers.
UNIX has had memory protection as far back as I was using it (early '90's). If your C program running on a UNIX system tried to access a memory address that it wasn't allowed to access, it would terminate with a message that said "Segmentation violation. Core dumped". This would also create a file named "core" which was some kind of memory dump that I never actually did anything with but delete it. DOS, on the other hand, would let you read or write anywhere in its 640K of addressable memory. If you tried to write to memory that the operating system happened to be using, the computer might turn unresponsive,and you would have to use the "three finger salute" (control-alt-delete), which in DOS would trigger an immediate reboot, except when it didn',t which was when you reached for the reset button (if the computer had one) or the power switch. I also remember that when a programming error in a C program read out of bounds on an array while outputting to the screen, you would get a screen full of garbage, often with "Microsoft Corporation" displayed somewhere in the middle of it.

IIRC, the memory protection worked best with hardware support; a UNIX system I worked on in the 80s was originally going to use Intel 286 processors, but the memory protection couldn’t be implemented properly, so they had to wait for the 386. They ran with 1MB of memory and a 20MB disk (though they ran better with 2MB and a 40MB disk).

Oh, and I analysed a few core dumps in my time, though it was not something I was an expert at.

I used to work with a guy who could look at the Blue Screen of Death in Windows NT 4.0, determine what was wrong, then use Norton Disk Editor to directly modify the hex code on the disk to fix the problem.

I was in awe.
