Europe, famous for its quality of life.
European Research Council: "The deadline to submit the review [for a 25 page proposal] is: 06 January 2026".
Dudes, I don't even live in the EU, I'm doing you a favor. (They even make clear this is not compensated.)

You should see how they all do with making a clock... updates every minute, and somehow most never get any better at it.. and those that do, will not necessarily in the next minute.

Told my husband that working with ChatGPT is like working with a semi-invested intern who’s never going to think about you or your business again when their internship ends.

This is like a hacker who can find gadgets in any binary to turn it into the instruction set that they want. Brilliant.

Every year, near the end of my accelerated intro class (0190), I've done the Halting Problem and briefly mentioned Rice's Theorem. It's finally(!) dawned on me that Rice's is more fundamental. Re-jigging class design! Also great to tie it up with, e.g., code.pyret.org .

I grew up a kilometre from MTR in one direction and Vidyarthi Bhavan in the other. That's better food culture in a 1km radius than entire countries have. (-: (BLR have plenty of slop, too, but you'd rather look at the most beautiful masala dosa in the world in your timeline.)

If you want to solve a problem, you can't just think outside the box, you should first convene a college of cardinals to define exactly what the box is and then decide in its licit or illicit uses. You know. Lateran thinking.

It's extremely frustrating to be sitting on one of the best ways to give students an intuition for NP-completeness, and have only a few dozen students at one university able to take advantage of it. (Hint: PBT.)

The Ashes - known to me as my biennial attempt to pass myself off as a cricket fan - gets underway this week.
There's something really very wonderful about 5 day, unlimited over test cricket that, for me at least, cannot be reproduced in T20, ODIs or any other audience friendly format.

Was not expecting this plot twist in a Tina Brown interview.
![https://www.nytimes.com/2025/11/15/magazine/tina-brown-interview.html
Tina Brown: I’m always being asked by young people, How do I get into journalism? Often I say you should go to India, because India, in fact, has a very vibrant literary culture.
Interviewer: I can’t believe your advice is go to India.
Tina Brown: [Laughs] Yeah, it’s not popular. When I say that, you do see the light fade from the eyes.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:ucjqs5d4mfb2bii7ta7cpur2/bafkreidc7pdkee3vmhb4wunsfkcwtivtnxeeks4wpae4xyhkcdnrfeoqqu@jpeg)

The first time I saw the Milky Way was actually when I was over 25. I'd lived in cities all my life. We want camping to New Mexico, and that first night out in the wilderness, I looked through our tent's mesh roof, said "wait, wtf", went out, and said, "Oh, *that's* what the ancients saw!!!"
Yeah. I knew that light pollution was a thing, but *seeing* lack of it firsthand is a different experience
