jona-f··on What should we tell our students?
Yes, looking at mathematicians, It's remarkable how such smart people can behave so stupidly. Looks like intelligence is overrated.
jona-f··on Bender: AI's 'Existential' Risk Is 'Fake' [video]
Not having known her before, I found this particular interview quite reasonable.

jona-f··on A Misalignment of AI in Mathematics
We'll need a lot of mathematicians to understand all that output. I'm not worried.
jona-f··on Abdominal fat predicts heart disease risk better than BMI
Sugar is a drug and this whole discussion beats around the bush.
jona-f··on Abdominal fat predicts heart disease risk better than BMI
Most importantly for A) is dropping sugar. Calorie restriction doesn't have to mean being hungry all the time. First drop sugar, you'll be hungry all the time until the withdrawal subsides, then eat at a slight calorie deficit. It doesn't feel different than a slight calorie surplus at this point. I do that and I am in complete control over my weight. This whole discussion seems totally misguided to me.
jona-f··on ICE to spend up to $20M on gloves that can deliver painful electric shocks
Yes, and if you are doing business with American companies, look for alternatives. The people should re-realize the power of a general boycott.
jona-f··on My server is a phone now
I think you are doing much better with an optiplex 3050 micro and libreboot. Android with it's locked down bootloader and outdated kernels is a dead platform. You are fighting Google's control at every step. Sad, the US used to be all about freedom...
jona-f··on Qwen3.8 Max now ranked as the best overall model by agentic index
How do you do the review cycles? Is this some automated feature of your harness? Do you have a generic prompt for this or ask 27B yourself?
jona-f··on China begins producing advanced chipmaking deep-ultraviolet lithography machines
Nah, you watch too many movies, they openly hired former asml employees.
jona-f··on Humans haven't stopped evolving
Who said we stopped evolving? Evolution is slow cause we are many. Another garbage clickbait press release that butchers the science.
jona-f··on Eight Newly Produced MQ-9 Reaper Drones Destroyed in Iranian Strike
Here's my hot take. Bush, Clinton, Obama, were all liars. Trump is actually the most honest president I experienced. Partly cause he is so bad at lying, but also cause he wants people to like him. People knew what they were voting for, he did not hide his idiocy.

We won't progress if we don't fix the mistakes that led to where we are. It's not just "Trump bad".

jona-f··on Einstein's relativity rules chemical bonds in heavy elements, new research shows
Chemistry is very empirical. While we today can explain nearly everything from physics, you still always have check how things will work in experiment, unlike in physic where you often can calculate the outcome of experiments very precisely from first principles.

To not have to resort to rote memorization you first have to have the interest. That way you accumulate the knowledge over time, then the patterns feel logical at some point. The logic isn't very precise, maybe that's where you have problems? Some molecules are similar in some molecules in this regard and other molecules in another regard. You will get a feel how stuff behaves. You certainly have a lot of chemistry knowledge you are not aware of.

For example, I'm sure you have a good intuition how things burn and you probably know the basics of why it burns. The invisible oxygen in the air is the main chemical insight to explain why stuff burns. You can explain the whole process to whatever detail you like with physics, but many chemists lack the math and physics knowledge to do much of that.

jona-f··on Show HN: Halo – open-source, tamper-evident runtime evidence for AI agents
Thanks for thinking this though and writing it down. There also still no proof of no tampering unless the agent is external and publishes right away. So maybe you could have a service that generates these, but then again, the service could just sign the logs.
jona-f··on Show HN: Halo – open-source, tamper-evident runtime evidence for AI agents
Yeah, if you edit the log you could make a new chain when you fully control the chain. And if you send the log to someone else, they can hash it themselves to see if you tamper with it later. I don't get it too. What is the chain good for?
jona-f··on Should DayQuil Be Legal?
You need much higher doses of dxm to get the psychedelic effects compared to ketamine. Ketamine is a pretty safe drug when used responsibly and occasionally, especially because you can slowly dose to the required intensity and it wears off quickly. Like any drug there are risks involved. Most notably psychosis and addiction. Apart from the immediate toxicity, of course. And that is very much higher for dxm in my experience. It's also a very weird trip and it took me a while (2 weeks) for my brain to fully settle again, whereas with ketamine I would bounce right back feeling better than ever, which of course increases its addiction potential. What we didn't know back then is that ketamine is actual toxic to the kidneys in prolonged high doses, so yes, be careful.
jona-f··on Should DayQuil Be Legal?
Came here to say this, the author is hating on dextromethorphan like he never robotripped before. But then, overdosing dxm isn't all that healthy and I'd recommend ketamine if you want to experiment like that.

jona-f··on Small Penis Rule
Yes, only men with small penises are allowed to court.
jona-f··on GPT-5.6 Sol Ultra will be in Codex
Why can't you reply to hn_user2? I just did. Did you say something mean to hn_user2 and now you have a restraining order and can't go near them within one reply?
jona-f··on GPT-5.6 Sol Ultra will be in Codex
How do you type the em dash. I thought the point about the em dash "—" is, that it is longer than the normal minus "-". Humans normally have no way to produce it, cause there is no key on the keyboard.

Thank you, we need more of you. Though, I don't think we will ever be "after the reproducibility crisis cleanup".
jona-f··on Is sunscreen the new margarine? (2019)
I agree, that article is suspicious. One thing, what if you are not at risk of heart disease? I'm not fat, fairly active, have a low blood pressure and use sunscreen to slow down skin aging. Lots of health advice does not apply to me, cause it is meant for the overweight population. There are the biggest possible health gains to have, so statistically everything that makes people less fat is going to "be healthy for humans".

When standing up from a longer squat I tend to blacken out a bit (never fully fainted) and this gets much worse with sun exposure. So I can totally confirm the underlying scientific finding of this article. Sun exposure does seem to lower blood pressure, but the rest is all conjecture and lacks differentiation.

jona-f··on The origins of the school system aimed to produce independent, critical thinkers (2024)
Having grown up in Germany I have firsthand experience how Humboldt's ideals fall short. I don't think I fully agree your explanation.

a) Teachers themselves went through this system, so if it's so great, it should produce plenty of great teachers

b) Now we are blaming the kids for the failure of the system?

c) Yes, absolutely, but is the bureaucracy really inevitable, or is it even contradictory to the original idea?

Anyhow, Humboldt's humanism was ideology from the start. It was a way to change as little as possible from christian values. Instead of God making humans all great now it is the great human mind and civilization.

By now, most of German academia is a bubble for humanistic fundamentalists, that have long lost their connection to reality.

jona-f··on What Ozempic does to the gut-brain axis
Your explanation doesn't seem plausible to me. If your stomach and small intestine is working properly, the bulk of the bacteria shouldn't see much sugar. Afaik the mechanisms how the intestines regulate the gut flora are not well understood. At least not to the point where there are any working treatment for the many widespread digestive problems. There is some slow progress around fecal transplant research.
jona-f··on What Ozempic does to the gut-brain axis
The "gut-brain axis" is mostly bullshit invented to cope with the fact that doctors have sent patients to shrinks for decades with real sicknesses. Everybody knows you feel bad when your digestive is out of balance. It's the same english word for "I'm sick" and "I feel sick" since forever. No magical newly found "gut-brain axis" needed.

Eating junk food, especially sweetened food is a drug. You can do a withdrawal and get the reduction of food noise reported with semaglutide without getting dependent on another drug with so far unknown long-term effects.

jona-f··on MiMo-v2.5-Pro-UltraSpeed: 1T model with 1000 tokens per second
glm 4.7 is quite old by now. I don't even use 5.1 anymore, cause I found kimi k2.6, mimi 2.5 pro, deepseek v4 pro and qwen 3.7 all better than glm 5.1
jona-f··on Benchmarks in Leipzig
Kimi K2.6 and mimo 2.5 pro are ahead of deepseek v4 in other benchmarks. Anyhow, great work, the benchmark seems to show great separation, so should be very useful to improve the math capabilities of the next generation of ai. I'm more interested in the prompt engineering/orchestration and technical details (what I can do without millions), but I get that you are mathematicians, so your focus is obviously on the math. Sorry for the nagging.
jona-f··on Benchmarks in Leipzig
Thanks for answering this random internet guy's question. It's a bit sad that a german math prof doesn't have sufficient funds to run a few prompts. I would have paid for them for this amount of advertising. I don't like that you gave them to a silicon valley company.

On that note, the tests are very US-centric. Only one chinese model and you unfairly nerfed it by limiting it's context window, when the compressed context is deepseek v4's main innovation and even with full context it is much cheaper to run than all the others.
