Remote Learning

Ohio in the early 90s had few educational options for a middle schooler interested in computers. But when there’s a will (and willing parents, thank you) there’s a way. Somehow I got signed up for a correspondence course in Pascal in 8th grade. Yes, an actual class where I never met in person (and only rarely spoke to the teacher on the phone). Where the majority of exchanges were via the good old fashion United States Postal Service. Where code had to be printed out, mailed, marked up, and mailed back (how’s that for slowing down rapid iteration!)

Despite it seeming painful to modern ideas of remote learning, the material was quite useful in my overall development. Up until then I was completely self-taught; reasonably good in BASIC and some rudimentary C. Learning Pascal, however, really opened up a new world. And luckily for you all, I still have a number of my Pascal programs, which I recently uploaded to Github for your browsing pleasure. Here’s the good stuff that awaits you:

• MARKET.PAS – This one’s special for two reasons. First, it’s the oldest of all these files, with a last modified date of Dec 6, 1992, making it the earliest example of code I wrote that I still have in digital form (the absolute oldest being this handwritten BASIC program from 1987). And second, it was my attempt to implement the Stock Market Game, a board game from the 1970s that my mom and I played together when I was a kid. No one else in the family ever wanted to join; it was kinda “our thing” (as was Scrabble).
• GRADE.PAS – A simple gradebook app for teachers. I believe this was the final project for my correspondence course.
• CYBER.PAS & CYBORG.PAS – Today you couldn’t pay me enough to get into video game development, but as a youngling I had a thing for trying to build them. This code is a tiny step towards what looks like a side-scrolling shooter involving robots and lasers.
• KARATE.PAS & KGRAPHIC.PAS – Another game effort, this one a fighter like Mortal Kombat, but with stick figures, because I am terrible at visual art. Pretty sure I got it to a reasonably playable state, though the mechanics were terrible and it required two people because there was no AI to speak of.
• JDNCRYPT.PAS – Built this encryption tool to protect DIARY.TXT, which I still have (but no, I’m not gonna share it). Basically I reinvented a simple rotation cipher using an insecurely predictable pseudo-random number generator, with an easily bypassed magic parameter kill-switch on the executable. How cute. Rule one of cryptography: never ever write your own.
• GAME133.PAS – In college a mathy friend of mine and I got really into the Number Jumbler. I wrote this solver to do research into combinations that had no solutions. Two years later when I started my first real job, I was tasked to learn Ada, and as part of that effort I ported this solver.

FYI, in upcoming posts I intend to expand on my personal tech history; including a visual history of my computer setups. Will it be of interest? Maybe! But I’m going to do it regardless.
