Ars Technica: I was frankly surprised at the ineffectiveness of the various intervention strategies you tested. But it does seem to explain the Bluesky conundrum. Bluesky has no algorithm, for example, yet the same dynamics still seem to emerge. I think Bluesky's founders genuinely want to avoid those dysfunctional issues, but they might not succeed, based on this paper. Why are such interventions so ineffective?

LLMs aren't world models

news.ycombinator.com Unknown 2025-11-24 11:40:14

I believe that language models aren’t world models. It’s a weak claim — I’m not saying they’re useless, or that we’re done milking them. It’s also a fuzzy-sounding claim — with its trillion weights, who can prove that there’s something an LLM isn't a model of? But I hope to make my claim clear and persuasive enough with some examples. A friend who plays better chess than me — and knows more math & CS than me - said that he played some moves against a newly released LLM, and it must be at least

Is your iPhone alarm not going off? 6 potential fixes that worked for me

zdnet.com Elyse Betters Picaro 2025-11-28 00:28:00

Elyse Betters Picaro / ZDNET I started noticing something very annoying at the beginning of the year: I'd set my iPhone alarm for 7 a.m., only to sleep right through it. At first I assumed it was my mistake -- maybe I'd accidentally left the ringer volume all the way down. But after double-checking that, even switching off vibrate and cranking the volume all the way up overnight, the problem persisted. Somewhere between frustration and desperation, I installed a third-party alarm app to try an

Hackers breach and expose a major North Korean spying operation

7 things the Galaxy S26 Pro needs to be my next Android phone

androidauthority.com Unknown 2025-11-29 05:00:48

Ryan Haines / Android Authority Samsung’s phone lineup hasn’t changed much since 2020, when the Galaxy S20 series set the precedent of a base, Plus, and Ultra model every year. There have been some additions, such as the more budget-friendly FE variants or this year’s thinner Galaxy S25 Edge, but by and large, the formula has been the same for the last five years. That could change in 2026, as Samsung may pivot to a Galaxy S26 Pro, Edge, and Ultra. If that is the case, the phone I’d be most in

The researchers use lasers to get each individual cesium atom to swell to nearly the size of a bacterium, about 10,000 times bigger than the usual size. Atoms in this bloated condition are called Rydberg atoms. When incoming radio waves hit Rydberg atoms, they disturb the distribution of electrons around their nuclei.
