Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

Built a live coding library for python that allows me to reload code I edited while it was executing. It has repl and debugger support and it can be run even for embedded python. It's pretty granular so it can reload modules or even individual objects. Unlike the existing module reload python function it can change object references to the updated code and delete old objects and their references from memory. This way in the next call only the latest code is executed. I built something similar for C code too.

I was just looking for something like this. Have you shared either of these publicly?
