If you look into advice from non-manufacturers (some other groups who are a bit less biased) it's widely recommended to max out at SPF 30, because any higher means sunscreen is harder to re-apply (meaning psychologically you are likely to not re-apply as often as needed) and also because it really doesn't make a difference unless you are ultra sensitive and have some kind of skin condition.

Yes, but you'll often find that in a high-deductible plan the insurance company gets a "discount" of your $1k med down to $200, which they brag about in your EOB… but the medication's cash price for uninsured people would be $20.

You're out of pocket $180 more than you should be, and paying the $20 cash price out of pocket means your deductible doesn't budge.

Drive thru conversations are not private under the Katz test, so there is no reasonable expectation of privacy. That makes video or audio recording in that setting lawful.

Katz came about because the FBI recorded a gambler outside the booth with the doors closed. Hence we have the Katz test.

Heck, you can even record someone making a drive thru order yourself and no one can do anything about it

It didn't achieve what Elastic wanted. It didn't lead to more people paying for Elastic licenses, it lead to users switching from Elasticsearch to a fork. And they eventually backpedaled and relicensed again under the AGPL.

Now, it might be better for the Open/elasticsearch ecosystem, because AWS is contributing more, and possibly the competition drives both Opensearch and Elasticsearch to be better. But on the other hand, there is now a split between two incompatible products, and Elastic has certainly lost some trust.

There's always a sliding scale between "proto-writing" and fully developed writing systems, but just using symbols phonetically instead of semantically happens much faster than that. The very archaic forms of proto-cuneiform is from about 3400 BCE (though things like clay tokens are much older). It, like virtually all writing systems in the world, developed into a true writing system by use of the "rebus principle", where symbols came to acquire different meanings based on phonetics in the same way as in a rebus. Like, in English, if you had a symbol for "female sheep" (a "ewe"), you could start to use it to signify the word "you", even though there's no semantic connection.

The earliest evidence for this in cuneiform is from around 3200-3000 BCE. There is a famous tablet where the symbol for "reed" is used to represent the word "reimburse", because they're both pronounced like gi. By a few hundred years later, cuneiform was a fully fledged phonetic writing system.

My dad acquired a dozen identical PCs from decommissioned office equipment at his workplace (very old machines slated for disposal). As a kid in a rural area, I had neither the money nor the means to obtain the necessary router to build the Beowulf cluster I'd been mentioning on a random IRC channel. Then, one day, a quiet "greybeard" who mostly lurked in the logs pinged me out of blue, asked for my address, and sent me his old 5-port router from Germany. This felt incredibly significant because even people who had interacted with him online for over a decade knew nothing beyond his screen name, yet here I was, holding a box with his full name and address.

This gesture, combined with the philosophy and work ethic of him and other greybeards that I deeply admired, literally changed the course of my life. By the time I reached high school, I already had an impressive portfolio of hardware and software projects, spoke fluent English, and was freelancing for amounts that exceeded my father's salary. IRC turned out to be an incredible ROI for me :p

I'm not sure how your confusion about what's going on is being projected to me. What about "also" what about "adjacent"?

>In my experience&training in a fintech corp- Accepting a settlement in any suit weakens your defense- but prevents a judgement and future claims for the same claims from the same claimants (a la double jeopardy). So, again- at minimum- this prevents an actual judgement. Which, likely would be positive for the NYT (and adjacent) cases.

Okay? I'm an IP litigator and you clearly have no idea what you're talking about. The only thing left to try in this case was the book library piracy. Alsup's fair use decision is just as relevant and is not mooted by the settlement and will be cited by anyone that thinks its favorable to them.

That's a separate effect, known as acromelanism, or "point coloration". It's the result of an enzyme which is inactivated by higher temperatures, not a genetic change - the extent of pointing can change over an animal's lifetime, and the specific pattern isn't inherited. (For instance, if you somehow convinced a cat with color pointing to wear a sweater, its fur would stay light under that sweater, but any offspring it had would not inherit that pattern.)

All the time. I have a UnitedHealthcare “platinum” plan, and it may as well not include pharmacy benefits because it never covers anything. Generic thyroid meds went from $2/month with Aetna to $70 with UHC. ADHD meds went from $10 to $300.

The threatened “death panels” we heard about when ACA was being debated are actually employees of insurers who decide what they’re not going to pay for.

I was raised a die-hard capitalist and in many ways still am. When it comes to healthcare these days, I’m somewhere to the left of Marx. What we have now is a failed system. It simply does not work. The turnip has been squeezed and there’s no blood left to wring from it.

Show HN: Whilio – AI chatbot that learns your site and explains user behavior
by duverse | 2025-09-06 22:24:42+00:00
I built Whilio after years in ads/sales where dashboards showed what happened but not why. Even with tagging, surveys, and A/B tests, it was still hard to see why users churn or convert. I wanted something that would ask questions in the moment and surface real themes from conversations.

What it does:

- Auto onboarding: crawl a domain, extract structure (products / docs / tone etc.), set its own tasks. Optional docs for overrides.

- Agentic RAG: per-page + global context, planner decides when to answer/ask/defer. Answerability checks reduce hallucinations.

- Data extraction: builds a lightweight knowledge graph, normalizes attributes/CTAs, tracks diffs.

- Insight triage: clusters language into Threats, Strengths, Opportunities -> real themes at scale.

- Environment-aware prompting: agent monitors page context, nav, messages, tasks -> decides when to engage.

What didn't work (and what changed):

- Vanilla RAG -> added answerability + planning.

- Noisy clustering -> switched to density-based + weak supervision.

- Manual curation -> replaced with automatic site learning + doc overrides.

Status: Open beta. Free demo w/o signup. Launching on PH.

Ask HN:

1. How to benchmark insight quality beyond pretty clusters?

2. Would you accept on-site "why" prompts at key moments?

3. Is self-hosting/on-prem a must in your context?

4. How important is to have SoC / ISO27001 for now?

I don't know if its been conclusively proven yet, but the more natural zinc sunscreens (not all zinc sunscreens are that natural, some of it is marketing) have mostly zinc (and a bit of some other stuff of course), while some of the chemical ones have an impressively long list of random chemicals. On that basis I personally believe a zinc sunscreen is less likely to have future unknown side effects.

I'm also in this situation where I have same kind of old iPad, which was lying in a drawer at my parents. It's running iOS 9.3.6, for which only a semi-tethered jailbreak exists. IIUC, this means that you can jailbreak it by side loading an app to the iPad.

The good thing is that you can do all this jailbreaking with free software from Linux, apparently. Of course it's endless browsing shadier and shadier / scammy websites before finding something that looks somewhat less shady. The world of iOS jailnreaking is very strange.

The bad thing is that sideloading requires an Apple account. I don't have one. Creating an Apple account from the device is not possible anymore. Creating an apple account from the apple website seems complicated. It wants a phone number which I'm not willing to give. I tried these services that provide burner public phone numbers to get the verification code it wants but have yet to find one that works. When i manage to get a verification code, it tells me that this is not possible at this time, please try from an Apple device. I don't have another one. I suppose I could try to run macOS in a virtual machine just for this.

I'd like to make this device useful. Up to recently I could use it to display music scores in PDF, I even wrote a web app for it to annotate them, but the screen is a bit broken and this makes the touchscreen very erratic to the point of being unusable.

I'd be happy to make it useful for something else but on the other end, I have other things more interesting to do than to deal with Apple's bullshit.

Too bad.

> This seems like a straw man

No.

You’re hired to do the job, what if you do the job in 8 hours?

Keep working if working is what you enjoy doing. Is the entire mission of the business “finished” after 8 hours?

> It also seems like a given that when you work at a startup that work life balance will be at a minimum. What more do you want?

To work somewhere where the other employees and the company leadership values the same thing.

There's no reason to avoid chemical sunscreens unless you have an individual allergy to some of the components. The concerns about them being "carcinogenic" or "disrupting hormones" or "killing the environment" is fearmongering and marketing bullshit pushed by "clean beauty" companies.

This is a good summary of the topic:

> Try to access it and TypeScript yells at you. No runtime validation needed.

I was recently thinking about type safety and validation strategies are particularly thorny in languages where the typings are just annotations. E.g. the Typescript/Zod or Python/Pydantic universes. Especially in IO cases where the data doesn't originate in the same type system.

In a language like Go (just an example, not endorsing) if you parse something into say a struct you know worst case you're getting that struct with all the fields set to zero, and you just have to handle the zero values. In typescript-likes you can get a totally different structure and run into all sorts of errors.

All that is to say, the runtime validation is always somewhere (perhaps in the library, as they often are?), and the feature here isn't no runtime validation but typed cli arguments. Which is cool and great.

How does that make it an energy source? It makes it a pump. That still consumes energy to run. And none of the home heat pump setups I’ve seen are tapping into enough thermal inertia (or high grade heat) to do more than keep a house warm. They also, of course, PUT HEAT BACK there in the summer to help cool the house. They’re just moving heat around, and not with any particularly high quality either. If they used the atmosphere for thermal inertia (also common), would you say they were using the atmosphere as an energy source?

Geothermal turns turbines with steam that then produces massive quantities of electricity. That makes it an energy source. The water way down under the ground in these cases is superheated by the surrounding rock, and provides plenty of high quality heat. There are no heat pumps involved.

It’s like the difference between having a pool in your backyard, and damming a huge river and installing turbines.

huh?

there is no concept of any single "default incantation" of any command -- every command always has multiple "incantations" depending on what you want to do with it

nobody would ever directly copy and execute any "exact flags" for any command based on a query string, surely this is not what you are suggesting?

I can get on board with a tool that's like tldr but broader-scoped, returning sets of commands that you could choose to run based on input query, but isn't this just claude?

Some people here in the comments are arguing that the LLM "understands" what is "true" and "false", that is somewhat capable of reasoning, etc, but I still find it quite easy (with GPT-5) to break its facade of "reasoning".

I asked it to play a word game. This is very simple, and a very short session too. It failed in its very first response, and then it failed in explaining why it failed. All with total confidence, no hesitation.

Nobody fluent in English would fail so catastrophically. I actually expected it to succeed:

https://chatgpt.com/share/68bcb490-a5b4-8013-b2be-35d27962ad...

It's clear by this failure model the LLM doesn't understand anything.

Edit: to be clear, as the session goes longer it becomes more interesting, but you can still trip the LLM up in ways no human "understanding" the game would. My 6-year old plays this game better, because she truly understands... she can trip up, but not like this.

I agree the model is predicting language and not actually running the math. That is a point I try to stress too. It is not thinking through a problem, it is predicting what text would look like if someone were working it out.

But the training does not just reinforce plausible continuations, it biases toward text that matches correct answers. So in that sense they are training it not just to predict any likely text, but to predict text that is more likely to contain the right answer to a math or coding problem.

To me that does not look so different from other ML models. They all work by turning a problem into something a computer can handle statistically, and they all face the same trade offs. Prediction errors are inevitable, and you still have to decide whether to tune for recall, which gives hallucinations, or precision, which gives refusals.

Agreed. The free market solutions to this problem are completely ineffectual. Nobody is paying a 3rd party to test sunscreen and even if they were, the results wouldn't likely be public and/or would be buried under the giant weight of mommy influencer blogs telling you to use apple cider vinegar instead of sunscreen.

The only way to solve the problem of bad actors in a consumer products market is government regulations, testing, and fines/dissolution of the bad actors.

But I found the actual footage more worth sharing. for actual nature, this is a tight & quality video, in terms of how much the subjects are in focus, but also in terms of the interesting features. e.g. the mock-bite behavior by the male, or the playful rolling by the female afterwards.

> or Paracetamol as we call it here in the UK

Mildly amusing anecdote: years ago I visited my then-company's office in London (I'm from the US), and fell sick during my time there. One of my London-local colleagues recommended I get "Night Nurse", and told me of the magical virtues of paracetamol. I'd never heard of it (either the brand name or the drug name), and assumed it was some great drug that for some silly reason the US FDA decided not to approve. It worked perfectly well, but frankly no better than what I'd take at home.

Much later I looked up "paracetamol" and discovered it's the same thing as acetaminophen... "oh, Night Nurse is just the UK version of NyQuil", I realized, somewhat disappointed, the magic lost.

> I'm always surprised at the hostility to Acetaminophen

I wouldn't say I'm hostile toward it, but the number one cause of headaches for me is alcohol consumption, and I was taught that alcohol plus acetaminophen is a strict no-no. Ibuprofen -- in the recommended dose -- is generally fine with alcohol. (I don't binge drink anymore, but as I get older, even 3 or 4 cocktails over the span of 4-6 hours can give me a headache later.)

But when I come down with a cold, it's (the cheaper, generic version of) NyQuil for me. A bonus is that NyQuil also contains dextromethorphan (cough suppressant) and doxylamine succinate (antihistamine) (or phenylephrine in the non-drowsy DayQuil variant), which IIRC Night Nurse/Day Nurse did not include. (Looks like it does contain dextromethorphan and promethazine now; not sure if it didn't back then, or if I'm just misremembering.)

MDS (Musk Derangement...)

I'm not trying to insult you, but think about this. Musk has a reputation of actually delivering on the things he showcases- Cybertruck is real, it also failed, but he delivered it. Starlink is real, and it is winning spectacularly and probably has saved countless Ukrainian lives at this point. Yes FSD is not there yet, but I can pretty much guarantee you that it will be the first car that (is not a taxi) that has it.

And breaking apart my own statement slowly for you:

Tesla robot will be the most advanced consumer grade product ever made ^ product ^ will have vision, grip, communication, ability to agentically think and perform physical tasks ^ Yes it is "a consumer grade product" that will literally not have real viable competition for a while

So please stop with the MDS so we can actually discuss the REALITY of the world.

Adhd will always be in season because it is a license to pill. Had Lezengreber won over Claridge we would have #SurelySchizotypal instead of #ActuallyAustistic but schizotypy will never graduate from 'more research is needed'. Schizophrenia might have been fashionable from 1940-1980 but it is hard to idealize after Reagan set them free. Anyway this is what Freddie writes about, he explains it much better than me because he's sick

https://freddiedeboer.substack.com/p/sick-people-are-sick

To quote:

... she has apparently recently received a vanity diagnosis of “ADHD and PTSD.” (This is a whole thing among more affluent patients with bipolar disorder, recently; I will just say again that there is no such thing as an ex-bipolar person.)

See also his take on Kanye West here:

https://freddiedeboer.substack.com/p/things-that-are-hard

The "neurodivergence movement" has captured a lot of people who are fleeing the stigma of severe mental illness note least the reality that at least 5% of people are on the schizophrenia spectrum and undiagnosed.

As for why I feel this way I got what was a very good psychiatric eval for a child 45 or so years ago. Today I can mark up the first paragraph with a highlighter and practically all of it is diagnostic of my condition but it was a pure headscratcher back then. I think it still is today and "ADHD" and "Autism" are fashionable differential diagnoses that obscure schizotaxia.

It doesn't help that there is so much emotional attachment to the construct of autism that a paper like this

https://www.princeton.edu/news/2025/07/09/major-autism-study...

that I read as saying "34%-90% of autistic people aren't actually autistic" stay firmly in the autism-affirming camp.

I believe dang has said there is an auto-flagger which will do that on posts that are getting too many controversial comments. Then a mod has to unflag it, if they want to do that.

Of course this does suggest a strategy for censoring topics that you don't want on the front page of HN: deploy a bot army to add inflammatory comments. I feel like I've seen effect on other posts (the tylenol post currently on the front page has that smell) but who knows.

Pretty good article. The title sounds clickbaity, but I don't think it really is. "Don't write bugs" should be understood in the sense of "don't bump into things when you walk," meaning simply that writing bugs in your code is something to be avoided in the first place, not something you accept now and try to fix later. It's kind of subtle but an important point. It's not that coding a bug means you're necessarily a Bad Programmer or not a Real Programmer, but it is something to be learned from so you can avoid doing it next time.

My understanding is that if taken in the recommended dose, and not taken for a longer period of time (consecutive doses, I mean) than the bottle says to, you don't end up with cumulative damage.

The damage should only occur if you take more than the recommended dose, or continue using it longer than the recommended period.

(Also not a doctor and this isn't medical advice.)

> what other sentient entity is available for consultation?

Surely you don't mean what you imply there? Not being sentient or available for consultation don't justify harming a person. A mother absolutely has a moral responsibility not to cause lifelong harm to the sentient entity her baby will later become. You wouldn't say excess alcohol consumption during pregnancy is only up to the mother's decision about her own body when there are adults walking around with terrible lives because of fetal alcohol syndrome.
