Random Positivity Thread: Happy Computer Memories
Random Positivity Thread: Happy Computer Memories
Time for some warm-and-fuzzies! What happy memories do you have from your early days of getting into computers/programming, whenever those early days happened to be?
When I was in middle school, I read an article in Discover Magazine about "artificial life" — computer simulations of biological systems. This sent me off on the path of trying to make a simulation of bugs that ran around and ate each other. My tool of choice was PowerBASIC, which was like QBasic except that it could compile to .EXE files. I decided there would be animals that could move, and plants that could also move. To implement a rule like "when the animal is near the plant, it will chase the plant," I needed to compute distances between points given their x- and y-coordinates. I knew the Pythagorean theorem, and I realized that the line between the plant and the animal is the hypotenuse of a right triangle. Tada: I had invented the distance formula!

- First furious madman scribbling: I had a toy was a "quizz" machine with "A, B, C, D" buttons, that read colorful perforated cards and a speaker of a "ding-dong" sound for a correct answer, I worked out what set of holes corresponded to what answer (which to the toymaker's credit, each card with the same answer did not have exactly the same holes) so I could always answer correctly. [The way I remember it I wanted to make custom cards, but maybe I was just a little cheater ^^]
- First program: One fond memory from middle-school, where our introduction to programming was writing GCM and LCM programs using TI-BASIC (or Casio, but the school really pushed the TI models forward). Also having access to a "worms" (somehow in basic and not assembly) clone copied from a friend's calculator, I reverse engineered the more easy aspects of graphical display, and input handling make a tic-tac-toe program. Since I didn't know about lists yet, inspired by the GCM and LCM bits, I used prime numbers to store the state of the board, and used divisibility tests to check it. (Some years later i would refactor it, to discover that lists are much much slower in non-assembly TI-BASIC, so it was accidental optimization) I also miscoded the bot, which was vulnerable to exactly one fork attack, but decided to leave it in because it was more fun that way.
- First hack: Discovering that the highschool's poorly designed web portal, for sharing homework and assignments, allowed forced browsing, which the files uploaded by anyone was fun. [I reported it to the school's sysadmin team, I swear]
- Cringe blog: Following in my geeky dad's footsteps I had a very teenager cringe website, that I look fondly on, with garish colors, self-made HTML, css and animated gifs.
