It's weird that GitHub shows time since the last commit, but not time since the first commit. It's a nice way of seeing how mature a project is.

I've been learning some Common Lisp by writing some simple JSON munging programs. I'm sure it's not best practice — I should probably deserialise to CLOS automatically — but it's a nice way to get comfortable with the basics. It feels weird deliberately ignoring helpers though.

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>.
