I hope they did their homework even after breaking the platform.
anyway i spent probably 10x as long on this and was happier because grinding repetitive math problems is fucking boring. so if he didn't do his math homework honestly who cares.
My second site was a blog in about 1998. I had never heard of a blog, but whatever. I built a user system, "karma" system, ability to spend karma (anyone with enough karma could post on my front page), an interactive choose-your-own-adventure story where you got to help write it, and some other features I'm forgetting.
Anyway, I built all that with flat files at first, because I hadn't heard the word "database" yet--even though I wrote this in PHP. As soon as I heard about databases, I converted it in a couple days.
