"Safety concerns". Yes most probably due to all the Chelsea tractors around them.
What does it mean for rhino horns to be worth more than gold? There are lots of ways to measure it.

All the world's rhino horns put together are worth more than all the world's gold put together? All of Africa's rhino horns are worth more than all of Africa's gold? A single rhino horn is worth more than a single bar of gold? 1kg of gold? The same mass of gold? The same volume of gold?

> So that’s Perplexity’s real innovation here: shattering the foundations of trust that built the internet. The question is if any of its users or investors care.

Ron Howard voiceover: They do not.
I had that happen to me once as well - it was an AT&T Wifi network and the auto connection was triggered by something in the carrier settings.
> At this point, Wired jumped in, confirming a finding from Robb Knight: Perplexity’s scraping of Forbes’ work wasn’t an exception. In fact, Perplexity has been ignoring the robots.txt code that explicitly asks web crawlers not to scrape the page

There's a distinction that is being missed between:

* Web crawlers automatically accessing pages, such as recursively following links to index them for search engines

* A tool accessing a URL in direct response to a user request

robots.txt is only intended for the former. For instance, archive.is state:

> [Why does archive.is not obey robots.txt?] Because it is not a free-walking crawler, it saves only one page acting as a direct agent of the human user. Such services don't obey robots.txt (e.g. Google Feedfetcher, screenshot- or pdf-making services, isup.me, …)

Perplexity do (as far as I've been able to find) respect robots.txt for their scraping. What the investigations confirmed it was ignored for was users entering a URL to summarise.

There is still a conversation to be had. I think users should be able to browse the web with whatever tool they want to - whether that's a standard browser, a minimal reader mode that doesn't show ads, or a statistical summarisation tool - but it does pose a problem for sites that rely on standard browsers letting them show users advertisements, get them to sign up to mailing lists, collect data, etc. if users decide to choose tools that don't allow that.

OK, but surely not everyone does this?

Here's the thing: if there really are kids out there who will drop dead within minutes of eating a sesame seed, surely some of them will discover this the hard way, i.e. by accidentally consuming a sesame seed and dying. But not once have I ever heard a news report about a kid dying this way, and I can't find any data on how many people die this way. I also can't imagine any reliable way that one could possibly learn that your allergy is so severe that a sesame seed will kill you without having at least some people actually die.

All this leads me to suspect that the belief that sesame seeds are potentially deadly in small doses might not be solidly grounded in facts.
And how do you think all the content creators (either mainstream or independent) are going to keep churning quality content if they get one order of magnitude less traffic than before, while the AI "answer engines" sell premium subscriptions to provide answers based on scraped content bypassing paywalls?

Isn’t it ironic that journalists themselves aggregate content in a way that discourages the reader from clicking through to the primary source?

This type of summarization and aggregation seems to be exactly what consumers want.
It’s actually fascinating to watch this one. You can see scripters fighting for control. I just watched all the checkboxes get unchecked within a couple seconds, followed by an equally swift counterchecking from the opposing side.

Love the user count too. That was missing from the first one.

It would be nice if it had a fixed zoom level so that messages like "hi" would show up the same for everybody. But given the scripting, I guess it wouldn’t matter anyway.

Now you know what you have to do next: add 8-bit color selection support. Then we can prove once and for all what HN’s favorite color is.
Star-shaped gold nanoparticles up to 200nm kill at least some forms of cancer;

> Spherical nanoparticles of 10 nanometers in size, produced in Cracow, turned out to be practically harmless to the glioma cell line studied. However, high mortality was observed in cells exposed to nanoparticles as large as 200 nanometers, but with a star-shaped structure. [...]

> "We used the data from the Cracow experiments to build a theoretical model of the process of nanoparticle deposition inside the cells under study. The final result is a differential equation into which suitably processed parameters can be substituted—for the time being only describing the shape and size of nanoparticles—to quickly determine how the uptake of the analyzed particles by cancer cells will proceed over a given period of time," says Dr. Pawel Jakubczyk, professor at the UR and co-author of the model.

> He emphasizes, "Any scientist can already use our model at the design stage of their own research to instantly narrow down the number of nanoparticle variants requiring experimental verification."

> The ability to easily reduce the number of potential experiments to be carried out means a reduction in the costs associated with the purchase of cell lines and reagents, as well as a marked reduction in research time (it typically takes around two weeks just to culture a commercially available cell line). In addition, the model can be used to design better-targeted therapies than before—ones in which the nanoparticles will be particularly well absorbed by selected cancer cells, while maintaining relatively low or even zero toxicity to healthy cells in the patient's other organs.

Holotomography:
https://en.wikipedia.org/wiki/Holotomography :

> Holotomography (HT) is a laser technique to measure the three-dimensional refractive index (RI) tomogram of a microscopic sample such as biological cells and tissues. [...] In order to measure 3-D RI tomogram of samples, HT employs the principle of holographic imaging and inverse scattering. Typically, multiple 2D holographic images of a sample are measured at various illumination angles, employing the principle of interferometric imaging. Then, a 3D RI tomogram of the sample is reconstructed from these multiple 2D holographic images by inversely solving light scattering in the sample.
The statement is false, unfortunately.

There's definite a positive (non-zero) threshold below which it doesn't trigger.

Yes, the fascinating thing about Matrix is that they have 30+ clients listed on their page of which none (!) implements all the features of the protocol — for instance, there is no client that supports E2E and multiple accounts.

You would think instead of creating more than 30 sub-par clients it would make sense to create one that is actually good.

"I don't think the US should care unless they want to get rid of that import loop hole law."

I am simply stating fact. US federal law allows you to import vehicles that are 25+ years old without passing any safety or emission law. The Japanese market is already different enough in safety compared to the US market. These cars are indeed death traps if you were to get in an accident with an equivalently old US car.
Except that they will see a lot less revenue and a lot less engagement and the creators will lose incentives to keep creating, to be clear I also wholeheartedly hate a lot of those practices but it's a fact that many of them increase engagement.
Oh no, I forgot about Norway!

I guess the blue would be for Norway then.
The weight and reinforcement of trees, poles, deer, etc. are difficult to change. Single-vehicle crashes cause more than half the crash deaths in the US[1].

I don't think the safety record of a motorcycle is a standard to aim for -- but even then a kei truck is at least twice the weight and likely has significantly less sophisticated brakes.

Clicking through to what, in person interviews with sources? Your comparison makes no sense
I would agree if newspapers stopped reporting on social media posts, for which they don't ask permission or pay royalties. Not to mention that most articles are just rewording press agency news releases and other publications.

And isn't Google stealing the content from the whole internet and making a huge profit from it? Why the double standard. Perplexity has links to sources too.
Right, I just realised this debate is basically the same debate towards ad-blocking and paywall jumping (e.g. via archive.is).

Of course opinions vary on HN but generally it feels like a "ad-blocking is cool, paywall hopping is cool, but the server also has the right to not give us the information".

Given this, this is pretty sensational reporting by The Verge -- calling it theft, comparing it to crypto, breaking the "foundations of the internet" (... the Internet is about sharing) etc. This is a non-story, we already have these tools, this just adds an AI summary layer on top.
That's cool but now do it with only html+css!

I like how my workplace does it -- there are rigorous codeowners and usually you only need approval from 1-2. if you do need approval from 5+, you can request a select 'super' codeowner review which will approve it for all.

What is wrong with un-checkers.

Quaternary ammonium compounds (quats) are commonly used as fungicides and disinfectants in hospitals, and I fear for the health-care workers that have to touch them all day.

I use git-cliff for my personal projects. If you follow conventional commits and squash merges, you get a clear, user-friendly changelog—it's easy to "skip" commits that don't affect the end user.

Where were we talking about seat belt safety?

US federal laws allows vehicles to skip safety/emission requirements if they are 25+ years old. Like I said, the US should not care unless we were to change that law. The car is still a death trap if you were to get into an accident with a US vehicle from the same time period.
You're right, if all you need is a queue with a small number of workers connected at low volume, you don't need Hatchet or any other managed queue - you can get some pretty performant behavior with something like: https://github.com/abelanger5/postgres-fair-queue/blob/main/....

The point of Hatchet is to support more complex behavior - like chaining tasks together, building automation around querying and retrying failed tasks, handling a lot of the fairness and concurrency use-cases you'd otherwise need to build yourself, etc - or just getting something that works out of the box and can support those use-cases in the future.

And if you are running at low volume and trying to debug user issues, a grafana panel isn't going to get you the level of granularity or admin control you need to track down the errors in your methods (rather than just at the queue level). You'd need to integrate your task queue with Sentry and a logging system - and in our case, error tracing and logging are available in the Hatchet UI.

The thing I'm struggling with as I read the official documentation and various blogs is exactly how this changes the developer experience. Do I get to remove `React.memo` and `useMemo` and never use them again? Is their use still useful for other cases? What do I have to think about when writing components so that I get this automagical memoization in some cases?
Sure, but that's not a fundamental thing, it's just a unit that's convenient to trade.

It's like wondering whether gold is worth more than Microsoft by comparing an ounce of gold to a share of Microsoft. Or to an ounce of Microsoft share certificates!

The only sensible way to make the comparison is by total market cap. And I seriously doubt that rhino horns are worth more than 15 trillion USD.

I think what Perplexity is trying to build is cool, but seems like they do quite a bit of dodgy shit.

On his recent appearance on the Lex Fridman episode, Perplexity CEO Srinivas admitted that they'd abuse Twitter's academic grant program and autogenerated thousands of grant applications with GPT.

If he so laughingly reminisces about doing that, I wonder what kind of other dodgy shit they do behind closed doors.

AI engines are the future of search and task solving. They will absorb a lot of information from their users, much more than old search engines, such as problem solving strategies, what works and what doesn't.

Just consider the fact that chatGPT as 180M users and probably solves 1B tasks per month. It collects contextual data, guidance and feedback on a massive scale, going into the next model with some PII and copyright mitigations.

We will go to LLMs for advice because they will have the best data, refreshed by hundreds of millions of users. LLMs will naturally collect the most up to date feedback from the world, they don't even need to do anything, just wait for users to copy paste the relevant data and provide iterative guidance.

I think this is fine, and it's no different from riding a motorcycle -- the primary risk is to the driver, who is free to assume their own risk. Someone else driving a Kei truck poses zero risk to me. If they understand the risk, then it's fine by me if they take the risk. They're also just much safer the slower they go. They make sense as fully-local or as city vehicles. 25-35 MPH are their sweet spot. Yes, they _can_ go on the highway, but probably shouldn't.
I have a thirty-five-year-old truck and it's still perfectly fine for my hauling needs but out of curiosity I looked at what new trucks or minivans might be appropriate replacements when the time comes. A huge fraction of the trucks I looked at were comically gaudy and large, even the base models oozed luxury, and most were clearly designed around projecting a certain kind of image rather than prioritizing utility.

I was reading about kei trucks when I came across Telo[1], a startup working on a US-legal electric kei truck. Depending on ground clearance that might tick every box for me even though I don't live in a city. They've got a steep hill ahead of them; I hope they succeed.

FYI, I work at Vectara and can answer any questions.

For us, we treat hallucinations as the ability to accurately respond in an "open book" format for retrieval augmented generation (RAG) applications specifically. That is, given a set of information retrieved (X), does the LLM-produced summary:

1. Include any "real" information not contained in X? If "yes," it's a hallucination, even if that information is general knowledge. We see this as an important way to classify hallucinations in a RAG+summary context because enterprises have told us they don't want the LLMs "reading between the lines" to infer things. To pick an absurd/extreme case to show a point, the case of a genetic research firm, say, using CRISPR and finding they can create a purple zebra, if the retrieval system in the RAG bits says "zebras can be purple" due to their latest research, we don't want the LLM to override that knowledge with its knowledge that zebras are only ever black/white/brown. We'd treat that as a hallucination.

2. On the extreme opposite end, an easy way to avoid hallucinating would be for the LLM to say "I don't know" for everything thereby avoiding hallucinating by avoiding answering all questions. That has other obvious negative effects, so we also evaluate LLMs for their ability to answer.

We look at the factual consistency, answer rate, summary length, and some other metrics internally to focus prompt engineering, model selection, and model training: https://github.com/vectara/hallucination-leaderboard
