I’m looking for some good, specific ideas on small ways to have a positive impact on the world on a daily basis.

What do you consider to be the highest return-on-efforts ways to make the world a better place for as many people as possible?

There is "Apple Machine Language for Beginners" by Richard Mansfield https://archive.org/details/Apple_Machine_Language_for_Begin...

I have fond memories from the late 1980s of trying to get the assembler contained within this book working, typing line after line of the MLX listing in. Unfortunately I never did finish it back then.

A week or so ago I got the urge to complete this project and I literally just finished getting the source in it to a point where it can be compiled online and then within an emulator: https://github.com/jlmcgraw/LADS_DOS33

For what it's worth, I was experimenting with this idea for Python (in an almost completely vibe-coded fashion) here: https://github.com/jlmcgraw/pure-function-decorators

Whether it's of any actual utility is debatable
