My brother, 4 years ahead of me, learned programming in college, and came home on breaks full of excitement about it. My mom, a high school science teacher, took a programming course at the community college. She ended up teaching the course a year later. I took a class in BASIC at my high school, around 1981. We used this IBM machine that looked like a keypunch but recorded the data onto an 8" floppy. Each of us got a floppy. We'd edit our program, then hand it to the operator, who would run it and give us our printout. Batch programming enforced a certain discipline -- you might get only a couple edit cycles every day. I wrote a program that made little mazes, using the built-in random number function RND. Then I made the maze a bit bigger, until I figured out what size would fit on a piece of 132 column green bar paper. I had little inkling of the order of algorithms, mine might have been O(N^3). Anyway, the next day I received a stern rebuke from the teacher, apparently the operator found it still running the following morning, and shut it down. I still love to program, though I'm not a software developer, but a so called "scientific" programmer.
