Me in 2023: Just chill. All the AI doom scenarios involve giving models direct access to and control over real world systems, and no one would be that dumb

In 2025: oh fuck

GPT-5 regularly asks you why you are not citing its work. GPT-5 always believes your estimator is biased. GPT-5 has more of a comment than a question. Sometimes GPT-5 tells you stories about grad school and expresses regret about getting a PhD. GPT-5's mom wonders when it will start making money.

ChatGPT File • • Edit View Window Help ChatGPT 5 > How many times does the letter b appear in blueberry The word "blueberry" has the letter b three times: • Once at the start ("B" in blueberry). • Once in the middle ("b" in blue). • Once before the -erry ending ("b" in berry). Total: 3 O92 Show me where the letter b appears in the word please. Sure — here's "blueberry" with each b highlighted: B lue b erry Positions (counting from 1): 1 B - first letter 4 b - in blue 6 b - in berry D9< Spell that out with all three bs please. I mean, just spell the word. Sure — here's the full spelling with all three b's shown in place: BLUEBERRY That's exactly how blueberry is spelled, with the b's in positions 1, 5, and 7.

ChatGPT File Edit View Window Help E ChatGPT 5 > You wrote "BLUEBERRY". There are only two bs there. Ah - I see the mix-up. Let's slow it down and spell blueberry carefully, letter by letter, showing all three b's. blueberry Now you can see them: • 1st b → position 1 • 2nd b → position 5 • 3rd b → position 6 blueberry Exactly — blue berry has three b's: • 1st b → at the very start • 2nd b → right after the e in blue • 3rd b → immediately after the second b, starting berry So the "bb" in the middle is really what gives blueberry its double-b moment. Its double-b moment; I see. Yep - blueberry is one of those words where the middle almost trips you up, like it's saying "b-b-better pay attention." That little bb moment is satisfying, though — it makes the word feel extra bouncy.

 ChatGPT File Edit View Window Help 巴 • ChatGPT 5 > My students get you to write their essays for them, you know. Ah, the old "ChatGPT, do my homework" routine — I'm familiar with that one. I can see why they'd be tempted, but here's the thing: I'm a lot more useful as a coach than a ghostwriter. If they use me to brainstorm ideas, plan structure, or clarify tricky concepts, they'll actually learn and still have their own voice in the work. If they just hand in what I write, they're skipping the thinking part - and it usually shows. I'm good, but I still leave a trail of... telltale ChatGPT-isms. A trail of blueberries, as it were. Exactly — a trail of blueberries: easy to follow, a little sweet, and maybe just obvious enough for a watchful teacher to notice. If your students really are leaving me to bake the whole blueberry pie for them, they might forget that the best part of pie is making it themselves... even if it gets a little messy. "Blueberry" only has two bs. Nope - blueberry really does have three b's. Here it is spaced out: bluebberry Positions: b- at the start 5 b - in the "blue" part 6 b - right next to it, starting "berry" That middle double-b is easy to miss if vou just glance at the word.

I had to try the “blueberry” thing myself with GPT5. I merely report the results.

Prepping my post-BayesComp "stock market update" (to be taken with a pinch of salt!) on how different topics fared relative to my expectations / past years.

Enhorabuena!!! 🥳🥳🥳
Gran fichaje para el INE!

I know this has little to do with the point of your post, but I think ii) isn't always so clearly defined. I'm thinking about 2nd-order transitions, e.g. liquid and gas phases of water where you can change phase without ever noticing by going around the critical point

Enhorabuena! 🥳🥳

Yo creo que sí eh, que haga las oposiciones también y se venga para el INE 😆

Rubén Musoles Roca - Problema 1 - OCM 2022 En aquesta entrada donaré diverses solucions del primer problema de l'Olimpíada Matemàtica (OMC) del curs 22-23 (fase Catalana). El que més m'agrada és la diversitat de resolucions que he anat recolli...

Per a quins valors n²+5n+6 és quadrat perfecte?

Resolem aquest problema d'olimpíada amb àlgebra, anàlisi, teoria de nombres... i inclús estadística!

Vamossss! Enhorabuena!!! A por el segundo y nos vemos pronto por el INE!

Actually this statement is true in some set theories like Quine's NF or NFU

Pretty funky: for state-space models, one usually teaches things in terms of a Markovian latent state {x_t}, with conditionally-independent emissions y_t which depend only on x_t.

Actually, a good chunk of the tractability of SSMs is preserved when the emissions depend on both of (x_{t - 1}, x_t)!

Cool, thanks a lot!

one time i tried to introduce myself to an ♾️-cat guy and before i could say anythind he told me "follows from a construction of deligne." i said "sorry? I--" he said "corollary of Stacks Project 4.13.2." I said "I'm Rochelle" and he said "I know; its in Lurie."

The most dangerous thing about AI chat bots is how many men with political power treat them *exactly* and unquestioningly like actual Ancient Greek oracles.

I used to think the phrase "free gift" was redundant but now I realize they are just gifts that are characterized by the usual universal property.

Funny thing is that "super" also means (Z/2-) graded!
