Last travel related thing. I have a friend who is about to get their fourth citizenship (among them US, all of them there are legit reasons for having gotten). Made me realize that the set of sets of compatible citizenships form a simplicial complex (some are not compatible with others).

Week 1 gets its signature moment when No. 16 Michigan beats Western Michigan on disputed finish
And to think, Kyle Whittingham said he wanted to put an end to all the drama around Michigan. Nobody could have scripted a more dramatic finish to the former Utah coach’s Michigan debut.

Social class creates a glass ceiling in organizations Lower-class folks are less likely to initiate negotiations than higher-class folks (N = 10,211), a pattern that can compound economic disadvantage over time.  This gap is explained by concerns about backlash  www.pnas.org/doi/10.1073/...

Almost every LLM that reaches a broad audience is quantized—compressed to run cheaply. USC's Emilio Ferrara argues this compression is treated as a safety nonevent, when it should be treated as a change to the deployed system. This has policy implications, he says.

Nerd thing: so there's this tech/math/nerd culture that's hard to describe, but where there's a kind of enlightened playfulness, which if you like you can trace very far back, and which perhaps hits a kind of high watermark with Claude Shannon, routes through late 60s/70s hacker culture, and so on.
