Programming

I am looking for old-school (html only, mininalist design) programming blogs, that are mainly focused on math, algorithms or systems programming. I also don't mind a few rants, movies or books reviews, but the content should be mainly technical. Preferred languages: C, C++, go, maybe Rust. Java or Kotlin are also cool as long as it is about the JVM, optimizations, but not Spring or Enterprisy stuff.

For example: https://nullprogram.com/ would qualify perfectly.

If not a list, maybe some links? A digital garden where you keep interesting articles it's also nice.

I prefer quality over quantity, you know the type of content that usually gets upvoted on hn, without the corporate bullshit or angel investment stuff.
