I made a short Rust course that builds a perceptron from scratch and trains it on basic logic gates, using a LEGO-style step-by-step approach. It’s free, but requires registration.
I relaunched Knowledge.Dev, and now I also generate free PDF books in Typst. I can say that even today, Typst's capabilities can fully replace LaTeX, while being incredibly convenient to use. All in all, I'm excited to share the results of my work over the past year.
