If they shut down the SSF and Colma stations, when I get RTOed and I'm forced to buy a car I'm going to drive 20 miles an hour everywhere and lay on the horn constantly.
10 stations that could close:
Castro Valley, North Concord, Oakland Airport, Orinda, Pittsburg Center, San Bruno, South Hayward, South San Francisco, Warm Springs, and West Dublin/Pleasanton
Some of these stations have significant potential for housing, but we can't get TOD without the "T".

Radio amateurs in Belarus are being charged with "High Treason" and "Espionage". Under the Belarusian Criminal Code, these charges carry sentences of life imprisonment or even the death penalty.

Reading through the replies/QTs and it's pretty cool how many people don't understand that this isn't real and the author makes UX mocks of hypothetical features.

None of this is really esoteric, but in 2025 I got into Warhammer, bought a 3D printer and made replacements for things, started (re)learning piano, and grew popcorn for the first time.
u heard sharon, everyone post about their esoteric interests right fucking now. for the good of the community, we need to be hyperfixationmaxxing.
i think this site really needs to figure out how to grow the non-politics verticals (the baseball moment was a good thing!) because i suspect a lot of the bad clusters come out of the political clusters driving 95% of ENG-lang posts
