Is it because most HN readers are _not_ in China that we lump together all scientific results as "China does thing"?

Is this also common for EU/USA? Do we say "UK developers new method for ..." or "Researchers at Cambridge"?

I swear I'm not making any political statements, just wondering why we treat it as a homogeneous entity.

> 6 months ago, "what temp is pork safe at?

No it wasn't, most of the first page results have the temperature right there in the summary, many of them with both F and C, and unlike the AI response, there is much lower chance of hallucinated results.

So you've gained nothing

PS Trying the same search with -ai gets you the full table with temperatures, unlike with the AI summary where you have to click to get more details, so the new AI summary is strictly worse

> Checklists to pack for vacation.

A thousand times yes. Here's an older version of mine: https://honeypot.net/2023/01/13/my-travel-project.html

While I'm on vacation, I make notes about things I've forgotten. Near the bottom of that list is a reminder to add those notes to the template so I'll do them the next time I travel.

My wife thinks I'm nuts. OTOH, I'm so much more relaxed before we depart because I know that I have everything I'll need for a fun, comfortable trip. And if I don't, it's going to be some relatively minor long-tail thing that's never come up before, not something basic like "pack underwear".

If a placebo or nocebo is cheaper than a costly medical intervention, then it's good as that if not better. The problem is: you name it placebo although patients (for example with rheumatological diseases) have really responded to it, sometimes equally good to medications. And rheuma diseases are real debilitating diseases, a placebo would no work so easily. The mechanisms of action of radon baths are potentially many, and many have been already described: 1. Hormetic Effect (Low-Dose Radiation), 2. Anti-Inflammatory Effects, 3. Immune Modulation, 4. Analgesic Effects (Pain Relief), 5. Neuroendocrine Regulation.

Again: unfortunately there will never be studies with thousands of patients to prove this or disprove this, because there is no money to be made. So we stay with the little proof have 20th century studies in Europe with the limited patients evaluated.
Show HN: Strava for Cooking
by cowllin | 2025-07-24 03:24:21+00:00
I love the niche social media of Strava. Use it as a personal log of your own exercise and/or a light-touch way to keep track of friends lives. Cooking is something we do 3+ times per week like exercise so I built this. I wrote 0 lines of code (not a programmer, just a lowly PM) and graduated form lovable to cursor to Claude code. All feedback welcome :)

1. You have entities, which may just be identifiers (maybe a u64 used as an index elsewhere) or some more complex object.

2. You have components, which are the real "meat and potatoes" of things. These are the properties or traits of an entity, the specifics depend on your application. For a video game or physics simulator it might be velocity and position vectors.

3. Each entity is associated with 0 or more components.

4. These associations are dynamic.

5. You have systems which operate on some subset of entities based on some constraints. A simple constraint might be "all entities with position and velocity components". Objects lacking those would not be important to a physics system.

In effect, with ECS you create in-memory, hopefully efficient, relational databases of system state. The association with different components allows for dynamically giving entities properties. The systems determine the evolution of the state by changing components, associating entities with components, and disassociating entities from components.

The technical details on how to do this efficiently can get interesting.

Compared to more typical OO (exaggerated for effect), instead of constructing a class which has a bunch of properties (say implements some combination of interfaces) and manually mixing and matching like:

Wizard: Player FlyingWizard: Wizard, Flying FlameproofWizard: Wizard, Flameproof FlyingFlameproofWizard: Wizard, Flameproof, Flying

Or creating a bunch of traits inside a god object version of the Wizard or Player class to account for all conceivable traits (most of which are unused at any given time), you use the dynamic association of an entity with Wizard, Flying, and Flameproof components.

So your party enters the third floor of a wooden structure and your Wizard (a component associated with an entity) casts "Fly" and "Protection from Elements" on himself. These associate the entity with the Flying and Flameproof components (and potentially others). Now when fireball is cast and the wizard is in the affected area, he'll be ignored (by virtue of being Flameproof) while everything around him catches fire, and when the wooden floor burns away the physics engine will leave him floating rather than falling like his poor non-flying, currently on fire Fighter compatriot.

> you simply have so much more on the big web ... and it's usually sorted by how interesting it is.

Getting away from that is a good thing. You shouldn't be interested in everything that is put in front of your face. You don't have the time for it and it's unhealthy to devote your time to consuming it. You should be aiming towards finding what you need, when you need it. You should be the one in command, not some algorithmic feed that is designed to capture and hold your attention.

> random people post random crap on their blogs

I have mixed feelings about blogs. While there are some excellent blogs out there, but it is also one of those formats that are meant to capture one's attention then have them come back for more.

> my RSS feed doesn't algorithmically filter it for me.

I haven't tried looking for it, but there ought to b feed readers that filter based on keyword.

This is about watermarking.

Combat Synthetic Media in the Legal System One risk of AI that has become apparent to many Americans is malicious deepfakes, whether they be audio recordings, videos, or photos. While President Trump has already signed the TAKE IT DOWN Act, which was championed by First Lady Melania Trump and intended to protect against sexually explicit, non-consensual deepfakes, additional action is needed. 19 In particular, AI-generated media may present novel challenges to the legal system. For example, fake evidence could be used to attempt to deny justice to both plaintiffs and defendants. The Administration must give the courts and law enforcement the tools they need to overcome these new challenges. Recommended Policy Actions • Led by NIST at DOC, consider developing NIST’s Guardians of Forensic Evidence deepfake evaluation program into a formal guideline and a companion voluntary forensic benchmark.20 • Led by the Department of Justice (DOJ), issue guidance to agencies that engage in adjudications to explore adopting a deepfake standard similar to the proposed Federal Rules of Evidence Rule 901(c) under consideration by the Advisory Committee on Evidence Rules. • Led by DOJ’s Office of Legal Policy, file formal comments on any proposed deepfake- related additions to the Federal Rules of Evidence.

> Also, what do these cops and government officials say about iPhones? iPhones, according to what I've heard, also have good privacy, is that not true? Is it not private enough for criminals?

By default, iMessage conversations are backed up iCloud with keys Apple has access to. Governments simply have to ask Apple nicely for the data, or serve them a warrant/subpoena/court order/etc. Apple has a web portal to automate this for them because of how often they share data.

For a while, iOS zero days were cheaper than Android exploits because they were so plentiful, but it looks like prices for iOS and Android exploits are about equal now, suggesting both platforms are similarly exploitable.
by anonym29 | 2025-07-24 03:26:10+00:00
Not only is there not due process for actual dangerous people, but the IC secretly collaborates internally and utilizes parallel construction to enable criminal prosecution of people who've been illegally targeted by mass surveillance and other capabilities possessed by global passive adversaries.

Ross Ulbricht's indictment relied in part on deanonymization through Tor likely performed by timing analysis at the global backbone level, but the investigating agency (FBI) conveniently isn't required to reveal their methods.

These days though, you don't even need to be guilty of horrific crimes like setting up websites that reduce real-world violence, merely publicly criticizing Israel is enough to have gangs of plainclothes deep state goons abduct and deport you, even if you're a lawful resident or citizen.

These are the dividends we're paid for trusting a government that acts like an organized crime group. Democratic oversight mechanisms mean nothing when the heads of the intelligence community can lead a criminal conspiracy to conduct unconstitutional warrantless mass surveillance of the entire country and lie about it to congress, like when James Clapper lied to Ron Wyden's face while under oath, and face no consequences for doing so.

Funny story, I used that to know the cooked temperature of burgers, it said medium-rare was 130. I proceeded to eating it and all, but then like half way through, I noticed the middle of this burger is really red looking, doesn't seem normal, and suddenly I remembered, wait, ground beef is always supposed to be 160, 130 medium-rare is for steak.

I then chatted that back to it, and it was like, oh ya, I made a mistake, you're right, sorry.

Anyways, luckily I did not get sick.

Moral of the story, don't get mentally lazy and use AI to save you the brain it takes for simple answers.

Does it matter? There's affirmative process for targeting people abroad believed to be involved in terrorism; that is to say: the FVEY IC is practically compelled to target them. It doesn't need permission from any court to do so.

You can argue that the legal protections from housing your data in US jurisdictions is marginal. I won't argue. But you can't argue that your legal protections are worse in the US, because the places you put your data outside of the US have no legal protections at all.

People always misinterpret these arguments as somehow sticking up for the US and the protections it offers residents. No. It's a descriptive argument, not a normative one.

I have the Google AI overview adblocked and I keep it up to date because it's an unbelievably hostile thing to have in your information space: it sounds truthy, so even if you try to ignore it it's liable to bias the way you evaluate other answers going forward.

It's also obnoxious on mobile where it takes up the whole first result space.

I’m on the list for an R2S to replace my Model 3, but it won’t be available until 2026 sometime at the earliest. Rivian’s problem is that they make one expensive car (in truck and SUV variants), and their market for that is saturating. Meanwhile I am literally trying to give them my money for a smaller SUV and they can’t make it fast enough. Not sure any of these problems are relevant to Tesla, which has a bunch of models that it can produce (and aren’t selling.)

I went to get new tires on my truck last month. 3 of the 5 bays at the tire shop had teslas getting new shoes. I asked the shop owner and he said EVs eat tires. Like 9-12 months max lifespan, great for business. I couldn't believe it but I've always heard there's exponential wear on tires relative to weight.

> that multiplies files by 9, or that subtracts squids from apricots

I don't understand why when someone mentions the word "dynamic", programmers automatically think javascript, php, bash or awk. Some dynamically typed PLs have advanced type systems. Please stop fetishizing over one-time 'uncaught NPE in production' PTSD and acting as if refusing to use a statically typed PL means we're all gonna die.

Gated how? It's all on textbooks, industry standards, Internet, everywhere. You could buy a KHR-3 without even driver's license for $1.5k cash for past ~20 years. I guess CUDA was technically gated behind "I swear I'm not a bad guy" button, but that was it.

I'm surprised that Ukraine isn't DIYing full-on solid motor cluster SAMs and armor piercing ATGMs. I thought those kinds of devices were something just about any sufficiently developed country can do in days to weeks should such national emergency arises and all bets were off, except nations in peacetime has moral obligations to do no evil.

Had not heard of it, thanks for sharing! I tend to think it’s good to follow one’s muse and make something useful for oneself and friends rather than over focus on “competitors”

I took this approach for my last two projects (Water Cooler Trivia and Twofer Goofer) and ultimately was able to scale and sell both with a lot of elbow grease!

Yes I know hallucinations are a thing. But when I had problems lile that better prompting (don’t make assumptions) and telling it to verify all of its answers with web resources

For troubleshooting an issue my prompt is usually “I am trying to do debug an issue. I’m going to give you the error message. Ask me questions one by one to help me troubleshoot. Prefer asking clarifying questions to making assumptions”.

Once I started doing that, it’s gotten a lot better.

Doesn't worry me. I believed AI would replace developers and I still do to some degree. But AI is going to lack context, not just in business domain but how it would intersect with the tech side. Experienced developers will be needed. The vibe coders are going to get worse and will need experienced developers to come fix the mess. So no worries, the only thing that would suck would be if the vibe coders earn more money and experienced hand crafting devs are left to pick up the crumbs to survive.

We (Geostar.ai) work with many brands and companies that have experienced near-death situations caused by Google's AI Overviews. The negative impact this feature has had on people's livelihoods is heartbreaking to witness.

Just today, I met with a small business owner who showed me that AIO is warning users that his business is a scam, based on bogus evidence (some unrelated brands). It's a new level of bullshit. There's not much these businesses can do other than playing the new GEO game if they want to get traffic from Google.

Who knows if Google will even present any search results other than AIO a few years from now.

This doesn't make sense. A Tesla weighs about as much as an SUV. We don't hear about SUVs eating tires.

If Teslas specifically are in the tire shop more, perhaps it's that Teslas ship with shitty tires. I've heard of a number of car makes that ship with really fragile OEM tires as a way to get you back into the shop for service.

People in the US haven't been buying small cheap hatchbacks for years. Look at how the Toyota Yaris, Honda Fit, Hyundai Accent Hatchback, and the Kia Rio faired in the US market.

Toyota, Honda, Hyundai, and Kia would have continued to manufacture and sell these in the US if there was demand, which there wasn't.

What I'm surprised by is the non-existence of an Indonesian owned and designed brand, but that's probably a result of the Asian Financial Crisis back in the day, but it's embarrassing given that historically poorer Vietnam has been able to incubate it's own domestic ecosystem for EVs and ICE cars. Indonesia has stagnated over the past decade based on developmental indicators and seems to be falling into the commodities trap instead of upskilling into processing.

Perhaps, but it is a historical fact that religions often define themselves on their moral superiority. Anyone can claim that their position is the one that is morally correct. If you just assert it without any supporting evidence, you're doing the same thing religions have been guilty of for a lot of history. In any case, it's not useful in the context of a discussion like this one, where it is little more than a blanket dismissal and adds nothing to the argument.

Thank you so much for these benchmarks. They really are for very specific use cases.

For Photoshop and Premier and Davinci: 16, 24, or 32 cores is really the sweet spot. Anything more gets negative results.

But for Unreal Engine, Blender, V-Ray, and Large Language Models, the 64 and 96 cores are significantly faster.

Almost all tire wear comes from accelerating and decelerating. Some from turning and cornering. Basically anytime you are asking them to stick to the road when the car's velocity is changing. Just coasting in a straight line does not cause any significant wear, regardless of weight. (Unless the tires are grossly under-inflated.)

EVs eat tires when people drive them like they're on a race track, which is most of the time.

Of course slow, shitty web sites also cause a massive drop in clicks, as soon as an alternative to clicking emerges. It's just like on HN, if I see an interesting title and want to know what the article is about, I can wince and click the article link, but it's much faster and easier to click the HN comments link and infer the info I want from the comments. That difference is almost entirely from the crappy overdesign of almost every web site, vs. HN's speedy text-only format.

I wholeheartedly agree. There are two great examples of this in the latest iOS beta:

In Safari, there used to be a button at the low right to reveal all the open tabs, allow, allowing you to close the current tab, or any other others using just two taps. Now you have to hit a “…” button, followed by ”all tabs”.

Also, I noticed in the podcast app there used to be a skip 15 seconds button always available at the lower right when content started playing. Perfect for avoiding those obnoxious loud ads at the very first sample of audio. Now it’s two clicks away. Incredibly frustrating.

Nice set of features you have here, very similar to Smalltalk (particularly Pharo) ideals. Actually I'm also actively working on a Pharo VM simulator so I can ultimately get GToolkit[0], which I really like and is based on it, running in Python.

Yeah, but just to be clear there's only ~1500 classes offered there. The 3000 comes from many of the classes having multiple components, lab etc.

The number is further reduced by the fact that many of them are the same class with special qualifications to ensure placements. For example intro classes for designated transfer students. So you have the same class but 10 seats or something are only available to certain transfer program students.

The real number looks like somewhere in the ~400-600 range. Which is still very impressive but 3500 different intro subjects would be wildly excessive.

These prices might be temporary, CCP is trying to crack down on deflationary pricing which is cannibalizing it's own internal markets. A product of competing provincial governments subsidizing their local companies with cheap debt and the overuse of promissory notes between vendors. It's resulted in a record number of bankruptcies and created a financial risk similar to China's real estate bubble.

https://www.youtube.com/watch?v=mbFE60Z-_VQ

Think: how Uber used VC money to offer cheap prices and undercut competition, but times hundreds of companies using government money driving the whole market down into fantasy land. Eventually prices have to come back to reality or the factories won't have capital.
