Coming from JS or Python, imports in Rust feel weird. They're entirely optional aliases for fully qualified symbols, which are always available. I don't know of many other languages where you can just start using libraries. Java is the only one I can think of.

TIL Advent of Code and Project Euler will deliberately look for puzzles where the naive solution is worse than quadratic. This ensures that people can solve them with any programming language. You don't want fast languages to be able to use the naive solution.

I find it really interesting how some areas of tech are widely expected to improve radically (e.g. LLMs and smart home tech), others gradually (CPU speed, battery capacity) and others very slowly (e.g. compiler optimisations). Predicting the future is hard.
