Configuring captive portal wifi without network manager or any aids beyond what’s provided by wpa-supplicant. Eventually I gave up, since it wasn’t really that important.

Adjusting freetype so that it works more-or-less the way I want it to, because the maintainers hate anyone who disagrees with their current hinting algorithm and make the setting as opaque as possible. I would prefer it if they allowed me to have hinting on some fonts and exclude only the ones that were designed to be pixel-aligned, but unless something’s changed recently, that option isn’t even offered.
