RULES
- Be respectful: no harassment, hate speech, bigotry, and/or trolling.
- Encourage conversation in your OP. This means including heavily implicative subject matter when you can and also engaging in your thread when possible.
- Avoid controversial topics (e.g. politics or societal debates).
- Stay calm: Don’t post angry or to vent or complain. We are a place where everyone can forget about their everyday or not so everyday worries for a moment. Venting, complaining, or posting from a place of anger or resentment doesn't fit the atmosphere we try to foster at all. Feel free to post those on !goodoffmychest@lemmy.world
- Keep it clean and SFW
- No solicitation such as ads, promotional content, spam, surveys etc.

Somewhere I have an image of a floppy disk containing the source and compiled version of a program I wrote for a Chaos Theory class in college in 1992.
It's a double pendulum simulator. Written in Turbo Pascal for MS Dos.
I wrote a rudimentary window management library for it. It had multiple panels for input and display. One panel allowed you to set the initial parameters for the pendulum (lengths, weights, position). One displayed the pendulum, there were a couple that displayed different graphs of the motion.
The last time I ran it was in the mid 2000's.
