One nice feature of cargo that I wasn't previously aware of: you don't need to do anything after updating your Cargo.toml. In npm, you need to remember to `npm i` after changing package.json. It's not declarative and the state can get out of sync.

Counter-intuitively, if you're writing a parser for a programming language, you need it to be a total function. As soon as you build IDE tooling, you need ASTs from invalid or incomplete input. The parser should return (Ast, List<Error>) rather than Result<Ast, Error>.

One day I am going to reach the height of technological sophistication, and every clock in my house will handle daylight savings automatically. I'm not there yet. I think modern appliances are getting better though. (Does a microwave really need to know the current time?)
