the horrific cornell gang rape case has me thinking about emma sulkowicz who alleged she was raped as a student at columbia in 2014 and never got any justice. it has me thinking about the physical and mental weight young women are forced to carry while their safety is subsumed by male potential.

Campus rape is really widespread; statistics suggest a significant percent of women who go to college will be raped there; feminism opened up a good conversation about it around 2012-13; it's weird when people treated Cornell like an isolated rather than dramatic example of a pervasive problem.

The idea that people want AI oversight to happen "all of a sudden" ignores years of research, warnings, and policy efforts. The delay hasn’t been a lack of awareness; it’s been because of years of industry lobbying against regulation, political resistance, and inaction.

One cool thing about ebikes? They make active transit way more accessible. I shredded my knees through high-impact athletics in my teens/20s, to the point where riding a non-e bike up a steep hill is awful. With an ebike, though, hills are no problem!

Banning diesel exports will make diesel prices higher in the U.S., especially in the northeast, where a lot of goods that arrive by ship at ports need to travel inland to US stores, carried by trucks and trains, that use,,,diesel fuel.
