That’s a very broad term. I don’t really know why I made this section, I just feel like I have a lot of things that I could write about programming that wouldn’t fit in any of the categories I have right now, so a general category it is.
I love esoteric programming languages and doing codegolf, so you will probably find a lot of that on here.
If you’re interested, I also have a page on numpy shape typing, which I think is an interesting read if you’re interested in Python type hints.
