jmmcd··on Tell HN: OpenAI keeps re-enabling the 'allow training' setting
Can't believe people are advocating free love in 2026
jmmcd··on Field measurements of neighborhood-scale air temperature impacts of data centers
AC at 68F is obnoxious and wasteful. At least data centres enable me to communicate with distant colleagues, watch enriching movies, and use very strong AI tools to accelerate my research.
jmmcd··on Professor denounces mass AI fraud on an exam at Brown
A lot of us went through a similar system and still retained both honour and desire to actually learn.
jmmcd··on Anonymous GitHub account mass-dropping undisclosed 0-days
It's interesting that Claude also over-uses en-dashes. It's very willing to create compound-noun-phrases, especially in that compressed-summary-paragraph it often writes. The 0-days-vibes-vulns that started this thread looks a lot like that, but it could be Claude directly, or just Claude's style influencing people who spend too much time with it.
jmmcd··on Claude Fable is relentlessly proactive
People are missing that Willison is among the very best people we have in the role of (for lack of a good name): early access to frontier models, evaluate them in real scenarios, no wishful thinking, hype, or doom, communicate the possibilities. Yes he could have fixed this himself but then he would have learned nothing about the AI, and we wouldn't have read a fascinating and important article.
jmmcd··on An OpenAI model has disproved a central conjecture in discrete geometry
> LLMs do just interpolate their training data

"interpolate" has a technical meaning - in this meaning, LLMs almost never interpolate. It also has a very vague everyday meaning - in this meaning, LLMs do interpolate, but so do humans.

jmmcd··on SpaceX says it has agreement to acquire Cursor for $60B
But euros spent on tokens is a tiny fraction of the overall costs of the project.
jmmcd··on AI Resistance: some recent anti-AI stuff that’s worth discussing
> Since these companies can’t improve their AI models without fresh data created by human beings

Totally wrong. Self-play dates back to Arthur Samuel in the 1950s and RL with verifiable rewards is a key part of training the most advanced models today.

Please, write US-American. These people are not coming from any other place.

jmmcd··on Ireland rolls out basic income scheme for artists
I understand your point, but in response to GP (they should spend this money on houses for other poor people instead), the reduced reliance on other social welfare is totally legitimate to count.
jmmcd··on Ireland rolls out basic income scheme for artists
You didn't read the article. The scheme gave positive return on investment.
jmmcd··on GPTZero finds 100 new hallucinations in NeurIPS 2025 accepted papers
Google Scholar provides imperfect citations - very often wrong article type (eg article versus conference paper), but up to and including missing authors, in my experience.
jmmcd··on Postal Arbitrage
Jokes are one of the good parts of human existence, so - while I see your side of the story - there is another side.
jmmcd··on “Stop Designing Languages. Write Libraries Instead” (2016)
The best example of all is Prolog. It is always held up as the paradigmatic representative of logic programming, a rare language paradigm. But it doesn't need to be a language. It is really a collection of algorithms which should be a library in every language, together with a nice convention for expressing Prolog things in that language's syntax.

(My comment is slightly off-topic to the article but on-topic to the title.)

jmmcd··on Gemini 3
But he actually uses frontier LLMs in his own work. Probably that's stronger evidence.
jmmcd··on Gemini 3
Yes. But "the gold standard" just means "the most natural, easy and dumb way".

"Pelican on bicycle" is one special case, but the problem (and the interesting point) is that with LLMs, they are always generalising. If a lab focussed specially on pelicans on bicycles, they would as a by-product improve performance on, say, tigers on rollercoasters. This is new and counter-intuitive to most ML/AI people.

About ARC 2:

I would want to hear more detail about prompts, frameworks, thinking time, etc., but they don't matter too much. The main caveat would be that this is probably on the public test set, so could be in pretraining, and there could even be some ARC-focussed post-training - I think we don't know yet and might never know.

But for any reasonable setup, if no egregious cheating, that is an amazing score on ARC 2.

jmmcd··on Altered states of consciousness induced by breathwork accompanied by music
On HN it's very common to see a blog post along the lines of "I found this old piece of equipment with no brand name, I used some network traffic inspection to figure out what it does, I hacked around a bit, I got it working and turned it into a self-ringing doorbell with wifi" (or whatever). All of that is anecdotal, N=1, "I did what worked for me, I hope it's interesting to you". And those posts are highly prized and rightly so.
jmmcd··on Quantitative AI progress needs accurate and transparent evaluation
(a) no it's not

(b) your comment is miles off-topic, as he is not addressing doom in any sense

jmmcd··on 'Positive review only': Researchers hide AI prompts in papers
But they're submissions to ICML.
jmmcd··on The 'white-collar bloodbath' is all part of the AI hype machine
It could certainly replace the author of this article.
jmmcd··on Trying to teach in the age of the AI homework machine
Modern LLMs can one-shot code in a totally new language, if you provide the language manual. And you have to provide the language manual, because otherwise how can the students learn the language.
jmmcd··on Trying to teach in the age of the AI homework machine
> The fact that AI can do your homework should tell you how much your homework is worth.

A lot of people who say this kind of thing have, frankly, a very shallow view of what homework is. A lot of homework can be easily done by AI, or by a calculator, or by Wikipedia, or by looking up the textbook. That doesn't invalidate it as homework at all. We're trying to scaffold skills in your brain. It also didn't invalidate it as assessment in the past, because (eg) small kids don't have calculators, and (eg) kids who learn to look up the textbook are learning multiple skills in addition to the knowledge they're looking up. But things have changed now.

Absolutely devastating for the credibility of FAIR.

jmmcd··on Baby Steps into Genetic Programming
No, you're confusing GA with GP.
jmmcd··on Baby Steps into Genetic Programming
> in genetic programming the goal is to find/optimize dataset to fit given algorithm

No. Possibly you're confused between GAs and GP, a common confusion. In GP, the goal is to find an algorithm - in a real programming language, not as weights - to optimise an objective function. Often that is specified by input-output pairs, similar to supervised learning.
