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

Your Brain on ChatGPT: Accumulation of Cognitive Debt when Using an AI Assistant for Essay Writing Task
This study explores the neural and behavioral consequences of LLM-assisted essay writing. Participants were divided into three groups: LLM, Search ...
 > 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.

Release of senior Israeli official facing serious child sex charges in Nevada stirs controversy and raises questions.
 > A senior Israeli official was arrested in the United States earlier this month and charged with seeking sexual conduct with a minor, only to be released on bail with no conditions or monitoring, allowing him to flee to Israel. > The case involving Tom Artiom Alexandrovich in Nevada is now stirring controversy, with politicians and social media commentators accusing the government of interfering in the judicial process to allow the cybersecurity official to return home without facing justice.

[...] > 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?

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?

Harry Mack - Top 50 Omegle Bars Vol. 1&2 (Official Video Album) 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.

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:

 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:

 - 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:

PSA: Probably going to disable LNURL messages below 100 sat payments in LN.tips - the spam has been going wild in recent days.
