I was never encouraged to do this; I came up with it on my own. Asked students to use an LLM to research something they already knew well, so they could spot problems. They were horrified. It was the only semester I haven't received an AI-generated assignment. 🤷🏻‍♂️

Thinking back to how instructors were encouraged to come up with exercises that had students using AI to recognize the limits of AI. This was in effect a tactic to bring AI into the classroom, even the classroom of an instructor skeptical of AI. Such cynical pedagogy.

When Jessica Watkins arrives at ISS, it'll be the second time 5 women are on space stations at the same time (Lai Ka-ying is currently on Tiangong). The first time was October 2022. This isn't the record due to the (notorious?) NS-31 mission that coincided with 3 women on space stations in 2025.

An oxidizer leak on the SpaceX Dragon spacecraft’s propulsion system will delay the planned Sept. 12 launch of the Crew-13 mission to the International Space Station. NASA says the leak was detected during standard prelaunch spacecraft processing. New date TBD following more tests. | Image: NASA

Space data centers being a thing essentially requires you to hit a 5 way parlay on: SpaceX actually cuts launch costs by 1-2 OOMs, AI has infinite returns to scale, terrestrial permitting issues are unsurmountable, chip production is no longer a constraint, and rad hardening/cooling in space is easy

The American Historical Association hired a lobbying firm to help silence member advocacy on Palestine. In this essay, Adam Rzepka covers @historians.org's relationship w/ Thorn Run Partners, its deep ethical conflicts, & the advocacy crisis AHA has thrust upon us. www.chronicle.com/article/a-sc...

Did the American Historical Association ask a corporate lobbying firm for advice on how to silence its members?

Okay, we all get the ridiculous emails begging us to submit our work to a fake journal or conference only tangentially related to our research. But even by those standards, this is really half-assed...

Screenshot of an email with subject line "looking for your valuable submission - Japanese journal of gastroenterology". Nonsense email address at "directivepublicationsc.org". Message text "dear name, the Japanese journal of gastroenterology is reaching out to you with a special invitation...."

The Trump-endorsed IndyCar race on the DC streets into a great unintentional advertisement for the effectiveness of raised crosswalks as a traffic calming measure

My favorite Soviet space dog is ZIB. Wikipedia: "Bobik ran away during a walk before the flight, but a replacement named ZIB (ЗИБ, a Russian acronym for "Substitute for Missing Bobik", "Замена Исчезнувшему Бобику" Zamena Ischeznuvshemu Bobiku),

Poor Laika the dog had been sent with no hope of return in 1957. Then in 1961, Gagarin orbited earth. In 1968 this craft (Zond 5) carried tortoises, fruit flies, & worms. We were so horrified that the Soviets had sent living things so far and succeeded, we launched Apollo 8 three months later.

The attempts to strip birthright citizenship & amend the Constitution by fiat is about subordination: to create a permanent underclass/caste of people without access to rights, protections, privileges, living in the shadows & ripe for exploitation. Plus making POC all suspects of illegality.

I think it's key to understanding their worldview that they imagine a world not *without* immigrants, but one in which immigrants' inferiority is permanently asserted and they become a subservient caste. All these people worship the Gulf States.
