Neat! Is it a CAS behind the scenes or if/then depending on which verb is selected?

PPS: I'm not sure how my tone comes across in these posts, because I worry my tech friends will think I'm being pessimistic and my arts friends the opposite. Personally, I feel like someone whose house is being eaten by nanobots, but who is really interested in nanobots.

"they don't deserve our fear" is a profound thing to say imo & I'm grateful for it

distrust yes caution yes. fear God maybe (proverbs 9:10 though I have long-winded thoughts about the fear of God). these men terrorizing citizens may be a lot of things but they don't know the first thing about God

It's so satisfying clicking the "return early" button in Libby. Especially when I know that I had to wait months to get my turn with a book.

@ryannorth.ca TBF, I do think of you as many things before I think of you as the guy who was stuck in a hole. But, when I think of someone stuck in a hole, I think of you first.

This sounds like a good video game set-up to me. Spaceship battles alternating with stealth missions. Maybe some base-building, too?

Why am I so against generative AI in games?

Because I simply do not want my initial reaction to art to be one of suspicion and scrutiny, AI slop is fundamentally damaging my relationship to art and artistry, and I am deeply resentful that it is forcing me to be guarded when I should be wowed.

In her #NWAV53 plenary, King discusses an example of a juror being dismissed from the pool due to forestressing in the word police (so PO-lice), because the prosecutor claimed that the pronunciation showed animus towards law enforcement. And this is exactly why I study prosody!

I'd say the skills are balance, power, foot position, etc. The tricks are the ollies or Yurchenkos or whatever--the applications of the skills. I'm saying we agree that doing without understnading is the problem, but I don't think this wording needs to be the hill to die on

Sure, but a skateboard trick, a gymnastics trick, or even a magic trick can't be done without understanding and practicing. I think the worry you are all having is when the trick is performed and I agree that this is bad. This is why I think it's semantics. I would call the problem algorithms

03.11.2025 17:53 β€” πŸ‘ 0    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

I suppose. But if I'm the one doing the trick, it doesn't seem like magic anymore? I guess I am thinking more of it as like a skateboarding trick than a magic trick--something I'm using my skill and knowledge to do.

Tricks like finding counterexamples, using the negative to prove by contradiction, taking extreme examples or simplified ones, etc. These are all tricks we use to better understand a concept and prove it using the properties, rules, and theorems you mention.

I disagree about not calling things "tricks" but maybe that's just semantics. There are all sorts of ways of thinking and different strategies that come up when thinking through mathematical ideas and I think of those as tricks in my bag to employ.

15. I started with the a% of b is the same as b% of a trick and 50% of 30 is half of 30, so 15.

Then I checked by doing 30% of 50 is the same as 15% of 100 (double and half thinking) which is also 15.

Joseph Barranco posted on social media: Go Bears! Nobel Prize in Physics goes to 3 physicists studying mesoscopic quantum phenomena... Work was done in the 1980s in UC Berkeley Professor John Clarke's lab with his graduate student John Martinis and postdoctoral fellow Michel Devoret... all 3 share the Nobel Prize.  Must also point out that both Clarke and Devoret are immigrants from the UK and France, respectively.  All 3 are pioneers in the race to build the most powerful quantum supercomputers.  California *public* education made this happen. Immigration made this happen.

Valuable info about the Physics Nobel Prize today from Prof. Joseph Barranco at SFSU on Martinis and Devoret being a grad student and postdoc in Clarke's lab at UC Berkeley & Clark and Devoret being immigrants. "California *public* education made this happen. Immigration made this happen." βš›οΈ

When we were in San Juan this summer, our Uber driver took us past the Paseo de los Presidentes and he said that it stopped at Obama. I told him that was enough and they didn't need to add any more.
