I'm having fun writing a simple type checker, but I'm learning firsthand why syntax-directed checking doesn't work. It prevents inference. My checker catches real bugs, but it can't handle cases like this: [1, 2].map(fun(x) { x + 1; }) I think I need bidirectional checking.

Do any tech streamers try new software live? It'd be a really fun way of doing UX testing.

It's rare to see ANSI escape codes for URLs in the wild, but cargo has it! This example links to https://doc.rust-lang.org/cargo/reference/profiles.html#default-profiles, describing the different profiles. Considering releases vs debug is a source of confusion for new users expecting better performance, this seems wise.
