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.

GNU Make defaults to a single worker, and newer build tools (e.g. ninja) default to the number of physical CPUs.I wish there was an option for 'leave me a little bit of my machine to do stuff'.
