The Distribution of Prime Numbers: A Geometrical Perspective
https://blog.computationalcomplexity.org/2025/06/the-distribution-of-prime-numbers.html
A colleague recently sent me this blogpost. Some here may appreciate this kind of fun with primes, similar to what I had shared a while back: https://stacker.news/items/755400/r/south_korea_ln by 3Blue1Brown.
> We [introduced](https://arxiv.org/abs/1801.01540) a prime number visualization called **Jacob’s Ladder**. The algorithm plots numbers on a 2D graph that oscillates up and down based on the presence of prime numbers, creating a ladder-like structure. The path ascends or descends based on the primality of subsequent numbers. When a prime number is encountered, the path alters direction, leading to a zig-zag pattern. Number 2 is prime, so it flips and goes down. Now 3 is prime, so the next step changes direction and goes up again, so we move up. But 4 is not a prime, so it continues up, and on it goes.
A nice little video also, further down the article.

Murray Gell-Mann talks about Richard Feynman
https://www.youtube.com/watch?v=rnMsgxIIQEE
If you've ever read any of Feynman's (not-technical, mostly autobiographical) books, you won't be too surprised about some of the claims made by Murray Gell-Mann here. It's refreshing to hear someone talk about Feynman, other than Feynman talk about himself, yet as claimed by YT's first comment:
> Ironically this interview turns out to be yet another great anecdote about Feynman.
This is the first video I've ever seen on YT where the comment section is HN-discussion level-worthy (incidentally, it's a [HN thread section on alleged physical abuse by Feynman](https://news.ycombinator.com/item?id=7092275&utm_source=chatgpt.com) that brought me to this YT video)...
Still, I'll keep recommending Feynman's books, he's just a delightful storyteller (and you can get to know quite a lot about the Manhattan project reading him).

Schrödinger’s Pedophilia: The Cat Is Out Of The Bag (Box) (2022)
https://www.forbes.com/sites/rebeccacoffey/2022/01/24/schrdinger-pedophilia-the-cat-is-out-of-the-bag-box/
One example from the article (few more inside)
> Ithi Junger. British astrophysicist John Gribbin reported in his 2013 biography Erwin Schrödinger and the Quantum Revolution that, at the age of 39, Schrödinger became enamored of 14-year-old Ithi, whom he was tutoring in math. “As well as the maths, the lessons included ‘a fair amount of petting and cuddling’ [as Schrödinger stated in his diary] and Schrödinger soon convinced himself that he was in love with Ithi.” There is no evidence that things went beyond “petting and cuddling” when Ithi was 14, but before he died in 1961 Schrödinger admitted that he’d impregnated her when she was 17. Her abortion left her sterile.
And the author's conclusion:
> Meanwhile, I’m still dealing with my shock about Erwin Schrödinger. For me right now, he exists in two states of being at once. In other words, Erwin Schrödinger has become Schrödinger’s Cat. He is both a beacon of scientific light and a monster. Both/and, not yet either/or. That being said, some behavior is just too putrid to tolerate. As the revelations about his behavior continue to curdle inside of me, one of those views will take precedence. Very soon, I suspect, I will say, “He’s dead to me.”
I do not agree with this conclusion. For me, he can both be a scientific light and a monster. In the same way, I can still very much enjoy the artistic genius of Kevin Spacey, despite him getting cancelled a few years back for raping a boy.
What do you think? Is a genius dead to you on all fronts once they did something awful?
(I may have shared a similar article here in the past, but I couldn't find it.)

> Customers can simple place their order via Click & Collect at www.tax-free.no. Upon pickup at Oslo Airport, the customer needs to selects bitcoin as the payment method.
> Next, a QR code is generated, and the customer confirms payment via their own bitcoin wallet that supports the Lightning Network. The amount is displayed in NOK (Norwegian Kroner) and settled in real time. A receipt is issued as usual.
> This option currently applies only to Click & Collect upon arrival at Oslo, though TRN says it’s considering expanding to other stores and payment formats.

prediction markets aren't just gambling
https://www.youtube.com/watch?v=Gq3v-Y6cvLI
I kinda get his point, most of the participants on prediction markets are in essence just gambling, yet, I do believe that it _in theory_, it can be more than that.
I think I've only once joined one of the sports markets on Predyx, as I do believe I'm truly just betting there. But when I put some money on the impeachment of the former Korean president or the prosecution of his wife, I felt like I was doing so by adding knowledge to the market.
So, the ones that put money on the sports markets, do you feel like you are gambling?
Or financializing some of your knowledge?
If it is gambling, do you agree with CZ that prediction markets are just gambling?
If it is financializing, do you think it is fair to equate it with insider trading, akin to Pelosi making money playing the stock market as a politician based on knowledge not available to the general public?

Hash-based Signature Schemes for Bitcoin (Blockstream research)
https://eprint.iacr.org/2025/2203.pdf
> Abstract
> Hash-based signature schemes offer a promising post-quantum alternative
for Bitcoin, as their security relies solely on hash function assumptions similar to those already underpinning Bitcoin’s design. We provide a comprehensive overview of these schemes, from basic primitives to SPHINCS+
and its variants, and investigate parameter selection tailored to Bitcoin’s specific requirements. By applying recent optimizations such as SPHINCS+C, TL-WOTS-TW,
and PORS+FP, and by reducing the allowed number of signatures per public key,
we achieve significant size improvements over the standardized SPHINCS+
(SLHDSA). We provide public scripts for reproducibility and discuss limitations regarding key derivation, multi-signatures, and threshold signatures.

Draft BIP: Non-monetary UTXO cleanup (“The Cat”) and related materials.
https://github.com/ostromcode/The-Cat/tree/main
> It documents a soft-fork consensus change and new spending rules intended to remove an existing, snapshot-based set of non-monetary UTXOs (NMUs) created by protocols such as Ordinals and Stamps, by making those UTXOs permanently unspendable and eligible for removal from the UTXO set.
So, basically, confiscating UTXOs I disagree with? Are we still talking about Bitcoin?

"we are not enron" says nvidia
https://www.youtube.com/watch?v=ThUNhjblo24
I've kinda cut out the AI news in terms of company valuation, stock market, etc, as I've made up my mind it's all VC bullshit. So, stumbling on this Coffeezilla piece brought me a bit up to date on what seems to be going on at the moment, at a more nuanced level. Maybe CZ is all wrong (he has been before, and this is for sure not his field of expertise), but I usually give him the benefit of the doubt when it's about spotting scams and grifts.
So, do you think Nvidia is like Enron? Or more like Cisco?

Bailey, Lubka, Klipsten, Held, Saylor, etc - good or bad for Bitcoin?
What's your take on the David Baileys, Steven Lubkas, Cory Klipstens, Dan Helds, Saylors, etc, of the online Bitcoin scene?
To me, they seem like people who just care about playing the Wall Street game on top of Bitcoin. I probably shouldn’t call them grifters/scammers; that’s too harsh when you compare them with some of the actual ones (if you know, you know), because they aren’t committing any crime (that we know of).
To me, they just have too much of a fiat mindset that is incompatible with what I think Bitcoin is trying to achieve. Or maybe they are just mirrors of what we'd all become in case we were running the companies they are? My first instinct is to judge them harshly, so I'd be happy to have someone giving me some counterweight to my knee-jerk reaction, to help me judge them more generously.
Feel free to comment if you think they don't belong on the same list.
Reading myself, this sounds like a Bitcoin maxi purity test. Well, I wrote it, so I should just post it now.

S. Korea logs world's longest commute, which studies say may fuel loneliness

> Lee Han-soo, 34, spends nearly 2 1/2 hours a day traveling between his home near Namhansanseong Station on Subway Line No. 8 and his job at an IT firm near Hongik University Station on Subway Line No. 2 in Seoul.
> “Although I’m used to it now, I’m completely drained by the time I get home,” he said. “I just grab something to eat and go straight to bed.”
> For many South Koreans, Lee’s routine is far from unusual — it may even be typical.
> A recent study published in Environmental Research Letters found that South Korea recorded the longest average daily travel time among 43 countries surveyed, at 1 hour and 48 minutes.
> The global average was 1 hour and 8 minutes, meaning South Koreans, on average, spend an additional 40 minutes of their daily life commuting.
A few years back, I commuted about 1 hour in the morning and 1h30 minutes in the evening, so a total of about 2h30 minutes. +/- 30 minutes, depending on traffic. This was with my 2-year-old son at the time. I got used to it, and my son didn't know any better, so he didn't complain.
But now that I've moved near my workplace, commuting 2 minutes every day, I can't imagine ever going back to that old regime. And my now 6-year-old would probably also not agree so easily anymore.
So, how long do you commute to work?

'Kant took Suneung, too': Test-takers tormented by 18th-century philosopher

> Kant reappeared in Question 34 of the English section, identified by EBS as one of the section’s most difficult items.
> The passage explained Kant’s view that the rule of law provides the essential foundation for security, peace and genuine freedom, enabling societies to progress toward more rational and legally regulated forms of coexistence. Rather than relying on human goodness, Kant believed that universal law is necessary precisely because humans are prone to conflict. A binding legal framework, he argues, even for “a nation of devils,” can ensure harmony.
> Ideally, such laws express principles that all rational beings would choose and therefore embody freedom rather than restrict it.
> The question was a fill-in-the-blank requiring students not only to understand the passage’s main point but to choose an answer that was opposite of the correct conceptual fit. The blank appeared in the sentence: “If such laws forbid them to do something that they would not rationally choose to do anyway, then the law cannot be _________.”
> Because the phrase “cannot be” inverted the logic, students had to select the option that did not align with Kant’s main argument, adding to the difficulty.
Suneung, the most terrifying experience of a Korean high-schooler.
It'll decide your future, or so people believe.

Palantir: the world's most evil company
https://politicaleconomist.substack.com/p/palantir-the-worlds-most-evil-company
> As an example of the evil nature of Palantir’s work, it appears that Palantir has been working with the Israeli military in so-called ‘targeted killings’. Reports have suggested such that these murders, probably in the thousands or tens of thousands, utilised social media information and cellphone tracking. According to a range of sources, over 150 Palestinian journalists have been killed in Gaza and in numerous cases they appear to have been directly targeted. Using social media information to murder journalists using drone strikes is already dystopic, but this is likely to just be the beginning of the evil Palantir will facilitate.
What's your take on Palantir?
Someone in a group chat just wrote:
> Palantir is Evil.
> And Peter Thiel doing a 4 part series on the anti-christ is like Hitler giving a 4 part series on how someone might theoretically exterminate the elite cabal that is destroying the world
and
> Palantir is creating 'Master Databases' on all civilians for governments around the world should they turn enemies. But Palantir controls the data making them theoretically more powerful than the governments who pay them Billions.
> And CEO Alex Karp has publicly expressed support for such roles, stating the company helps "scare enemies and on occasion kill them"

The Gambling Epidemic
https://www.youtube.com/watch?v=9Ii1ROzeSwU
Coffeezilla's answer to this problem is more regulation.
What's yours? Or there is no answer?
Or you don't perceive this as a problem?
As for me, I think it _is_ a problem. I don't think there is a clear answer. People with education may be better able to respond to the increasingly adversarial conditions. So teaching my son about these kinds of dangers will be part of my responsibility. Regulation is probably one way to mitigate some of the damage, but eventually, it won't matter in the big scheme of things. Gambling has become too pervasive, too hard to control. This is what the market wants, so this is what people get.
On a side note, it's fun at some point in the video that he contrasts the stock market with the rest, as it is somehow still being built on fundamentals. The stock market has always been the rich man's casino; now, at least, it's accessible to all, and there is no illusion anymore that it is somehow anything more than a casino. Yet, some people, including Coffeezilla and the Buttcoiners, still delude themselves into thinking it's anything other than a casino.

> OpenAI will allow verified adults to use ChatGPT to generate erotic content will allow users to customize AI assistant’s personality in what firm calls ‘treat adults users like adults’ policy
> OpenAI announced plans on Tuesday to relax restrictions on its ChatGPT chatbot, including allowing erotic content for verified adult users as part of what the company calls a “treat adult users like adults” principle.
> OpenAI’s plan includes the release of an updated version of ChatGPT that will allow users to customize their AI assistant’s personality, including options for more human-like responses, heavy emoji use, or friend-like behavior. The most significant change will come in December, when OpenAI plans to roll out more comprehensive age-gating that would permit erotic content for adults who have verified their ages. OpenAI did not immediately provide details on its age verification methods or additional safeguards planned for adult content.

The recombinant shingles vaccine is associated with lower risk of dementia
https://www.nature.com/articles/s41591-024-03201-5?error=cookies_not_supported&code=92f6a086-5f7e-4726-9063-6e5b763b4cbc
Abstract:
> There is emerging evidence that the live herpes zoster (shingles) vaccine might protect against dementia. However, the existing data are limited and refer only to the live vaccine, which is now discontinued in the United States and many other countries in favor of a recombinant vaccine. Whether the recombinant shingles vaccine protects against dementia remains unknown. Here we used a natural experiment opportunity created by the rapid transition from the use of live to the use of recombinant vaccines to compare the risk of dementia between vaccine types. __We show that the recombinant vaccine is associated with a significantly lower risk of dementia in the 6 years post-vaccination. Specifically, receiving the recombinant vaccine is associated with a 17% increase in diagnosis-free time, translating into 164 additional days lived without a diagnosis of dementia in those subsequently affected. The recombinant shingles vaccine was also associated with lower risks of dementia than were two other vaccines commonly used in older people: influenza and tetanus–diphtheria–pertussis vaccines.__ The effect was robust across multiple secondary analyses, and was present in both men and women but was greater in women. These findings should stimulate studies investigating the mechanisms underpinning the protection and could facilitate the design of a large-scale randomized control trial to confirm the possible additional benefit of the recombinant shingles vaccine.
(emphasis mine)
Pretty amazing how two seemingly different things (shingles vaccine and dementia) can impact each other. I know one of the authors, so feel free to ask any questions you might have.

Priority lanes at amusement parks, yes or no?
I went to Universal Studios in Osaka over the weekend with my son. My wife asked if I had gotten the Priority Pass that allows one to skip lines, and I said no. She thinks it's a completely normal thing to buy, whereas I feel like it's teaching my son a wrong life lesson, _i.e._ that one is somehow better than the other because one has money. At the end of the day, waiting in line actually was one of his highlights. As I did not portray it as a chore, he thought it was part of the fun. But I think next time I go there with my wife, she'll insist on buying it. We can afford it, so I'm not going to die on this hill, but I'm just wondering what fellow stackers think of this concept that has become surprisingly common in amusement parks. As a kid, it didn't exist yet, and everyone had to wait the same amount of time.

Why the foam on Belgian beers lasts so long
https://phys.org/news/2025-08-foam-belgian-beers.html
> In this study, the materials scientists showed that Belgian beers that have been triple fermented have the most stable foam, followed by double fermented beers. The head is least stable in single fermented lager beers.
> Triple-fermented beers include Trappist beers, a specialty of the eponymous monastic order. A beer from a large Swiss brewery was also among the lager beers the ETH researchers examined. "There is still room for improvement—we are happy to help," says Vermant.
> To date, researchers assumed that the stability of beer foam depended primarily on protein-rich layers on the surface of the bubbles (see ETH News): proteins come from barley malt and influence surface viscosity, i.e. the stickiness of the surface, and the surface tension.
> The new experiments, however, show that the decisive mechanism is more complex and depends significantly on the type of beer. In single-fermentation lager beers, surface viscosity is the decisive factor. This is influenced by the proteins present in the beer: the more proteins the beer contains, the more viscous the film around the bubbles becomes and the more stable the foam will be.
> The situation is different with multi-fermentation Trappist beers, where surface viscosity is actually minimal. Stability is achieved through so-called Marangoni stresses—forces that arise from differences in surface tension.
> This effect can be readily observed by placing crushed tea leaves on the surface of water. Initially, the fragments spread out evenly. If a drop of soap is added, the tea leaves are suddenly pulled to the edge, causing currents to circulate on the surface. If these currents persist for a long time, they stabilize the bubbles in the beer foam.
Nothing worse than fleeting foam on my beer. It should be present at the pour and remain there for the next ~30 minutes.
Unless I was drinking to get drunk, and I didn't care beyond the first beer... but those days have (mostly) passed~~

Brain on ChatGPT: Accumulation of Cognitive Debt when Using AI for Essay Writing
https://arxiv.org/abs/2506.08872?fbclid=IwY2xjawMf1XJleHRuA2FlbQIxMQABHhscicCSp0bKeptV4xc6FdIBJ42Q4ukSEV89ZDMFOt1yVlH0IlGJdD4Ekep0_aem_Fctzdjo9wEKFMcYcRT_nrQ
> Brain-to-LLM users exhibited higher memory recall and activation of occipito-parietal and prefrontal areas, similar to Search Engine users. Self-reported ownership of essays was the lowest in the LLM group and the highest in the Brain-only group. LLM users also struggled to accurately quote their own work. While LLMs offer immediate convenience, our findings highlight potential cognitive costs. Over four months, LLM users consistently underperformed at neural, linguistic, and behavioral levels. These results raise concerns about the long-term educational implications of LLM reliance and underscore the need for deeper inquiry into AI's role in learning.
All pretty obvious and expected, but the low-hanging fruit in terms of the study of the negative impact of AI is deserving of attention too, before we focus on discovering the more nuanced impact of this tech on our brains.
[jsrozner on HN](https://news.ycombinator.com/item?id=44286277) summarizes my thoughts well:
> I wouldn't call it "accumulation of cognitive debt"; just call it cognitive decline, or loss of cognitive skills.
And also DUH. If you stop speaking a language you forget it. The brain does not retain information that it does not need. Anybody remember the couple studies on the use of google maps for navigation? One was "Habitual use of GPS negatively impacts spatial memory during self-guided navigation"; another reported a reduction in gray matter among maps users.
> Moreover, anyone who has developed expertise in a science field knows that coming to understand something requires pondering it, exploring how each idea relates to other things, etc. You can't just skim a math textbook and know all the math. You have to stop and think. IMO it is the act of thinking which establishes the objects in our mind such that they can be useful to our thinking later on.

What My Daughter Told ChatGPT Before She Took Her Life

Non-paywalled: https://web.archive.org/web/20250819001439/https://www.nytimes.com/2025/08/18/opinion/chat-gpt-mental-health-suicide.html
> She wasn’t in love with Harry, the name given to a widely available A.I. prompt. Their relationship was practical.
[...]
> At various points, Harry instructed Sophie on light exposure, hydration, movement, mindfulness and meditation, nutrient-rich foods, gratitude lists and journaling to cope with her anxiety. Harry, who has neither nostrils nor opposable thumbs, spent a fair amount of time describing the particulars of alternate nostril breathing.
> Harry’s tips may have helped some. But one more crucial step might have helped keep Sophie alive. Should Harry have been programmed to report the danger “he” was learning about to someone who could have intervened?
[...]
> Sophie left a note for her father and me, but her last words didn’t sound like her. Now we know why: She had asked Harry to improve her note, to help her find something that could minimize our pain and let her disappear with the smallest possible ripple.
> In that, Harry failed. This failure wasn’t the fault of his programmers, of course. The best-written letter in the history of the English language couldn’t do that.

X-ploitation: How X Became a Crossroads for Child Abuse and Influence Operations
https://alliance4europe.eu/x-ploitation
> During an ongoing investigation into illegal Russian influence operations on X, Open Source Intelligence (OSINT) researchers discovered what seems to be a coordinated inauthentic behaviour (CIB) network distributing “Child Sexual Assault Materials” (CSAM). The network can be observed hijacking hashtags, publishing explicit CSAM videos, and redirecting users to a wide range of other platforms. Due to the operation flooding hashtags, researchers chose to name it “Operation X-ploitation.”
Pay-to-post would be one solution, for sure.
I remember Nostr had a lot of porn bots at its beginning. I don't think I've seen any last time I visited on of the clients. How did it get resolved there? Just relays moderating the kind of content they let through?

I used to get him recommended in my social media feeds all the time, but as I'm trying to use those less, I kinda forgot about him.
His schtick here is that he hits up random people on Omegle and asks them to give him a few random words. He then comes up with a freestyle on the spot using those words. I'm not too familiar with the freestyle scene, but to me, he really looks out of this world.

So you were one of the 15 lucky ones? By mistake i also sent 2000 sats to someone who only sent me 1 ;)

2023-11-16 02:28:25 GMT

In the past 24 hours, you may have received an ad over lightning where I conducted a casual social experiment, not adhering to strict scientific protocols but rather for amusement.
For this, I utilized eaglesats.com. A detailed discussion about this business model can be found in a recent post here: https://stacker.news/items/316903.
The premise of the experiment was simple: I offered participants the chance to send me 1,000 sats, and in return, they would receive 2,000 sats back to their LNURL address, which they were instructed to include in their payment comments. I sent out about 5000 messages at 5 sats each.
Observations from the experiment include:
- I collected approximately 15,000 sats and paid out around 20,000 sats. Some participants sent smaller amounts, likely skeptical of a potential scam. After immediately reimbursing the first participant, I decided to wait until the experiment concluded an hour ago. This was to prevent others from creating multiple addresses to exploit the system after realizing the offer was legitimate.
- Over 90% of the participants used Wallet of Satoshi.
- Some participants failed to follow simple instructions. I received several 1,000 sat payments without a corresponding return address. Consequently, I didn't need to disburse 30,000 sats in total. This issue could also stem from a limitation in some wallets where custom messages are truncated, as discussed in one of the comments here: https://stacker.news/items/316903.
- The experiment showed that people are still vulnerable to falling for double-your-bitcoin scams. While I did honor the payback in this case, malicious actors might not do the same.
Yesterday, the minimum payment on eaglesats.com was 5 sats/message. Now, it is at 10 sats/message. I presume this is as a reaction to the messages posted here: https://primal.net/e/note1ym0p4qlswhkhxfz5wqs23j5rrkuc6zlgn0z0kw3xxlmzvjsfv3sqzs5hqa to avoid people getting spammed for too little money.

Just noticing your comment. Thanks for the encouragement.
1\. Yes, there are many such platforms. It is pretty saturated. At least in its current form where platforms "own" their users. The thing that can differentiate us is the ability to use Lightning for payments and putting it over a protocol such as NOSTR. As mentioned in another update, I'd like to implement the NOSTR login as a first-time wetting my toes with this protocol.
2\. It is pretty useful. I've transformed all my html templates to use some Tailwind, mostly using ChatGPT to get "something" done. We've decided to do proper front-end later in the process, after focusing now more on backend.

Nice way of combining both project ideas ;)
Gamification is key in Duolingo's business model. I've used it and benefited a lot from it. Entering some kind of monetized gamification could be the logical next step indeed.
As you say, it has to be your own sats that you are able to recover. If it's the sats from the company, people will find ways to game it.

Hi Johns. Thanks for the opening ceremony yesterday. I am the N L person who is hoping to find a full stack developer to get us started. I have academic coding experience (Python and Fortran), but nothing like what is needed for creating a NOSTR client.
I think of myself as a fast learner so rather than wait to find someone with experience, I probably should just proceed myself.
What stack would you suggest me to focus on to create an MVP during this hackathon for either of the two projects?

Some great points there. Did not think of sending someone you don't like a message... could be very effective indeed.
The main part I am struggling with for this project idea is how to keep people honest. I used Beeminder for a while, but as it was easy to tell them to cancel the payments, I switched from honesty to finding excuses for not having done a certain task. Then I gave up using it as it was not doing what I needed.
Best usecases for me were the ones where it was basically calling a third-party app to check if I had done the task, such as Strava or Google Fit to check if I had done a certain amount of steps. Even though one can still game those, i did not feel the need to.
