expreg is a great alternative to expand-region, that's #TreeSitter aware. I can't believe I didn't discover it earlier! (technically speaking - I discovered it last year, but I forgot to update my init.el to actually use it :D )

I surveyed 112 major source-available projects to understand their AI contribution policy and whether or not they have actually accepted explicitly-labeled AI contributions.

Only 4 projects banned AI completely: Zig, NetBSD, GIMP, and qemu. 70 already have AI-assisted commits.

Helsinki just went a full year without a single traffic death The capital city is Finnish’ed with car-related fatalities.

β€œHelsinki hasn’t registered a single traffic-related fatality in the past year…Citing data that shows the risk of pedestrian fatality is cut in half by reducing a car’s speed from 40 to 30km/hr, city officials imposed the lower limit in most of Helsinki’s residential areas and city center in 2021.”

Last week, at the Uffizi, I ran into one of the many portraits of Isabella Brant that Rubens painted. I spent some time drawing her while I was in art school, so she seems like an old friend whenever I see her 😊

STOP LAUNCHING CRAP WE DON'T NEED OR WANT

It's staggeringly depressing how blithely they plan to ruin everything. Everything.

I went to a dark site last week so I could say goodbye to the sky. Took a little hand-held photo and guess what? A satellite trail appeared.

Just stop!
