I hope the person who reminded you was me
I mean, my entry below vaguely fits...

Also, I did Computing A Level myself. Twice, in fact. Our teacher thought Fortran was still too new to be trusted, typed with one finger, and was infact nothing more than an untrained technician. He would waste entire lessons of my time coming up with solutions to a problem I had put to him by saying "well, what if you changed x and y? Then you could solve it like this...", completely ignoring the fact that changing x and y would have meant re-arranging the insides of a factory down the road where my client worked.

Ooh, and on the first attempt, one of the major questions in the exam was on how a digital camera worked at an electronic level. CCDs, and so on. None of this was in the syllabus. Tar and feathers were involved in the resolution of this problem.

despite thinking I'd never seen your frankly quite amusing username before.
