0 for 3 hotels this trip, which is especially crappy mid semester.
Sigh.

I miss conference Tw!tter.
I'd post more (at all??), but the hotel wifi is mostly what wifi.

Not to be outdone, another class currently has 16/21 AI papers (that are all but identical), and I still have 2 left to read/grade.

Cornell folks, please join us for a teach-in next Monday! We'll be talking about WTF is happening nationally and right here on campus.

US news comes across as completely batshit when you’re outside of the US. Pretending I don’t speak English because I cannot explain this degueulasse.

Reading about the AWS-Canvas debacle yesterday. It's hard not to project this to when when it's STARLINK and military comms...except it won't be students and profs unable to communicate with each other.

Canvas, the course management platform used by my university (and many others), has been down all day due to the AWS outage. It has prompted some good discussions about how much critical infrastructure is now outsourced to a few companies.

I found this a really illuminating thread on what demonstrations do and why they matter.

Thank you for sharing, Karl. These essays, and your son, are extraordinary.

Is there current or emergent research (and support!) looking at ALS and non-speakimg autism?

Y’all here is a fun fact: Portland has a brand new volunteer organization called “operation inflation” that allows people to borrow inflatable costumes for protests. They just started a couple weeks ago and have like a 160 costume library (and counting because people keep donating).

One thing I always hear from heroism experts is that doing small courageous things equips us to do big ones later on.

It's dark skies season! 🌌

Autumn is the perfect time of year to get out for a spot of stargazing. To make the most of the dark skies, why not get involved in the Cumbria Dark Skies Festival, 24 Oct - 21 Nov, and experience unique night-time adventures.👇

A US startup plans to deliver ‘sunlight on demand’ after dark. Can it work – and would we want it to? Satellites beaming sunlight down to Earth sound like science fiction – and they have astronomers very worried.

A US tech startup is proposing to use mirrors in space to power solar farms on Earth at night. Is this even feasible? And what are the light pollution dangers?

Myself and @mattkenworthy.bsky.social have crunched the numbers for The Conversation.
