I don’t disagree that there is value in the accessibility of knowledge.

I cannot read sheet music. I lack such experience. That experience is earned from practice. Likewise architecture is a skill earned through practice. My experience has taught me:

1. It cannot be communicated to the inexperienced developer because they do not understand it. Sometimes they will pretend to understand it and just superimpose a hasty, wrong, interpretation on top of it that just reinforces some singular aspect of comfort.

2. When architecture is defined in terms of goals it is better understood by business owners and project managers than inexperienced developers. They may not understand the code and conventions but they can frame the second and third order consequences in terms of measures, risks, and effort.

3. You can generally identify those capable of architectural discussion by where they invest their interests. When the conversation never rises above syntax and vanity, as in how to write code, the higher level considerations of organization and structure become lost and lofty.
But they don’t need to because it’s been summarised already. So I get nothing while perplexity make more money.
We haven’t seen algorithms that build world models by observing. We’ve seen hints of it but nothing human like.

It will come eventually. We live in exciting times.
It’s propagates through the supply chain, loading, logistics, wear on vehicle transport etc.

We should practically get to the point where someone can buy a roll of material at Home Depot and unravel it on their roof, nail it, and plug it in themselves.
Coziness of cops to DAs and prosecutors, most likely:

> King County Prosecutor's Office decided against filing criminal charges against Dave. Manion stated that the criminal review did not turn up enough evidence to prove beyond a reasonable doubt that Dave had acted with recklessness or criminal negligence, as required under Washington State law. The decision drew widespread criticism from communities in India and the US.

That is the criminal side. To the earlier point on liability or protection therefrom:

> The Kandula family declared their intent to pursue civil actions against Dave and the Seattle Police Department.
Nobody follows robots.txt, because every site's robots.txt forbids anybody that isn't google from looking at it.

Also, "hiding their identity" is what every single browser does since Mosaic changed its name.
Website owners should be able to block this behavior as well — OpenAI has two different agents and doesn't obscure the agent when a user initiates a fetch.

TL;DR from the article is a newbie pushed the column forward by accident and corrected very quickly. Dropped from 600 feet to 400 feet at a rate of 4,000 feet per minute. That’s about three seconds of too-fast descent at a constant 4,000ft/minute, though it wouldn’t have been constant so it may have been a bit longer that that, mostly at lower rates of descent.

Not some huge plunge. Worth an investigation but the headline’s clickbaity.
Then they should just say that outright instead of pretending they right thing.
Please stop interacting with me.

I've had discussions with you on HN before and they were fairly acrimonious. If there were block functionality on HN I'd do it to you.

I don't want to get banned on HN for flame wars.
Evidence tends to bear this out. People aren't walking around with gobs of unused ability; they're usually performing about where they're able.

My experience has been the opposite. I think most people are underperforming to their potential, mostly because they lack social connections or knowledge to capitalize on it, or even begin to take the first steps to capitalizing on it. The number of intelligent people stuck in pointless jobs is endless.

The tech startup world is a good example. There are so many intelligent people which simply haven’t even considered the possibility of building a tech company, mostly because they aren’t exposed to it, don’t have any friends or family members doing it, etc. It’s an unknown-unknown that has nothing to do with ability.

It’s more likely that those who are already successful like to rationalize that “everyone is exactly where they should be” as a way to justify their own positions.
How does it compare to kanata and kmonad?

Found especially kanata a delight to use, while being both minimal, if needed, and maximally feature-filled if desired.
This just seems like a fundamental misunderstanding of what an LLM is, where people anthropomorphize it to be akin to an agent of whatever organization produced it. If Google provides search results with instructions for getting away with murder, building explosives, etc. it’s ridiculous to interpret that as Google itself supporting an individual’s goals/actions and not misuse of the tool by the user. Consequently banning Google search from the AppStore would be a ridiculous move in response. This may just be a result of LLMs being new for humanity, or maybe it’s because it feels like talking to an individual more so than a search engine, but it’s a flawed view of what an LLM is.
One of those situations where it’d be advisable to examine the recorded telemetry. Prediction: the car wasn’t in self driving mode and the owner just wanted a get out of the jail free card. This happened several times in the past.
Noteworthy, and probably related to the release of this report is the lazard 2024 LCOE report FINALLY got released in early June.

Been programming since 98, professionally since 08.

If a codebase has no VCS.. that seems almost ideological. I've done a git init on a linux file system to understand patch changes.

With that aside, what does disaster recovery look like without VCS? Remote backups ate an obtuse form of VCS.

If your laptop explodes, are you losing months of work? I mentor junior devs to push daily, if their laptop blows up I want them set up again in 30 minutes with at most one days worth of work lost (because they push their branches remotely, if only for the redundancy. Doing so daily makes it easy to recreate what was lost, compared to a week or two of effort).

Without VCS, integration is s larger challenge. It can be done, but continuously and also efficiently?

Seemingly we are talking about non collaborative code bases, a vanishingly small subset of projects. Most software is developed by teams.

Last, it is so damn easy to run 'git init'. My last job - the team used git locally and then did the stuff in TFS when they finally had to. The point is how easy and useful it was. The other guy that did his own thing, did not use VCS, his stuff was scary. His code was disaster if it stopped building, of if we lost his laptop.

Which is to say, VCS is an underpinning for CI & CD, DR, and is stupid easy to get the init setup done. Just about any codebase - yeah. Even if that means doing git locally and then throwing it away.

It is different to choose to not use all the tools compared to not being able to use them, and yet another to be unwilling to learn them either due to prejudice.

Don't get me wrong, the PR review is still rigorous and can take weeks. But everybody I interacted with during the process was very supportive and helpful, so the overall experience was great!
The bi-invariant metric as pointed out by chombier is what I have in mind. I agree that a non-canonical metric may be the right one for some applications, but those are the exceptional ones. The bi-invariant metric (which has a simple, geometric meaning given by Euler's rotation theorem) is the right starting point for thinking about distances in this space.

(Your reference [2] supports this point of view: read "simplest" as "canonical". Your reference [1] claims five distinct bi-invariant metrics, but this is wrong. The argument given is that any metric related to a bi-invariant metric by a "positive continuous strictly increasing function" is itself bi-invariant, which is not true.)
If you are referring to slerp, the matrix version is trivial using the log and exp maps.

slerp(A, B, t) = exp(t log(B A^T)) A

Something more complex like splines, I am not familiar with the algorithms used for quaternions. I would bet they use Lie algebraic operations, but do they actually use anything specific to quaternions?

Not disagreeing that quaternions have some computational advantages over matrices, but most of the points people repeat as "advantages of quaternions" are really "advantages of proper Lie group/algebra operations over Euler angles" that are independent of matrix vs. quaternion representation.
I think people did, to some extent. "Not an apple fanboy, but..." is a sentence i've heard more than once. But apple's figurehead never made as much of a habit as acting publicly obnoxious, not even during the steve jobs days
What are the dark clouds in space?
I think you may have your conditional probabilities backward? P(research-related|origin-place) and P(natural|origin-place) do sum to one, since those are mutually exclusive and exhaustive outcomes.

P(origin-place|research-related) and P(origin-place|natural) don't, though. For example, if "origin-place" is "anywhere in the universe", then they're both exactly equal to one, so they sum to two. If it's "Mars", then they're both approximately zero.

The virology institute (again, not just any virology institute; the single largest collection of novel related viruses in the world by far) doesn't decrease the probability of natural pandemics. It increases the probability of research-related pandemics, so natural becomes a smaller fraction of that larger total.
Setting a correct user agent isn't required anyway, you just do it to not be an asshole. Robots.txt is an optional standard.

The article is just calling Perplexity out for some asshole behavior, it's not that complicated

It's clear they know they're engaging in poor behavior too, they could've documented some alternative UA for user-initiated requests instead of spoofing Chrome. Folks who trust them could've then blocked the training UA but allowed the alternative
Care to elaborate? As I see it, the only restriction on embedded systems the parent has added is that it usually lacks filesystem access or dynamic memory allocation.
You are trying to focus too much on money and control. Instead focus on experience, are you learning new things, are you somewhat enjoying the process.

There are ways to communicate your objections without triggering other person defensive response.
Nukes are far bigger now and there are cluster warheads which enable carpet nuking which would not leave survivors.

They have dial a yield warheads especially designed to reduce bluntness and enable / encourage tactical use.

Then there is neutron bombs that are designed to focus on killing the people and leaving the infrastructure.

It used to be presumed that any real conflict would start out with nuclear weapons and for now that is unthinkable. I hope it stays that way but there is no divine reason for it to. Just traditions and norms that are easily swept away. I remember a time, not that long ago, when arming drones with weapons was unthinkable. Then we did it and now it’s being done to us. I worry that the ‘unthinkable’ nature of nukes is being used to push red lines as far as possible. The same way the unthinkable systemic crash of the housing market enabled the very leverage that caused it. The same logic of ‘Russia will not use nukes because they have not yet used nukes’ which elides the fact that there is always a first time. And like weaponized drones, once it starts it’s really hard to stop.
I hate to argue this side of the fence, but when ai companies are taking the work of writers and artists en mass (replacing creative livelihoods with a machine trained on the artists stolen work) and achieving billion dollar valuations that’s actual stealing.

The key here is that creative content producers are being driven out of business through non consensual taking of their work.

Maybe it’s a new thing, but if it is, it’s worse than stealing.

Hierarchical Navigable Small World
I can see where you're coming from, and I'd say your first paragraph is spot-on. Although, talking about “the hand of fate” is missing a lot, I think. Elizabeth's success comes from her authenticity (see https://www.existentialcomics.com/comic/46), Mr Darcy's comes from his bettering himself, Lydia gets conned (and Mr Darcy arranges a marriage to at least preserve her social status, since happiness wasn't really an option for her after that)… Really, the only person in the story who gets what they're initially after is Mrs Bennet, and possibly Elizabeth (I don't remember whether she was against marrying someone wealthy, or just objected to marrying for wealth).

> I'd argue saying it's about "status hierarchies" is not particularly informative.

Saying it's about "status hierarchies" is only slightly more informative than saying it's about humans. (Note: there are plenty of books about neither.) I brought up Pride and Prejudice to begin with in order to make this point.

> I'd wager 1% or less of readers, if asked what the novel would summarize it as being about status hierarchies.

I would be inclined to agree.

If you have a usb NIC, chances are it has a male plug so it can connect directly to a computer without an extra cable.

If it has usb A male, it can connect to a large number of computers, but nothing from Apple recently. If it has a usb c male, it can connect to recent Apple computers but has limited ports on other computers and can't connect to older computers.

If it has a usb-c and a usb-a male to usb-c female dongle (often attached to the little bit of cable between the device and the plug), then it will work with everything.

If you clip off the dongle, then you can use it to connect usb c male devices to usb-a female ports in lots of useful applications. It violates the spec, but it's super handy. If you have a usb a male to usb c male cable, you can use the forbidden dongle and the allowed cable to make a forbidden usb a male to usb a male cable which is probably not useful for much.

Sweet Baby Inc extortion scheme exposed
I think using the PIO on a Pico to drive a Tayloe mixer could be very productive. My interests are in multichannel SDR for doing passive radar.

I first thought I could use a square wave, and an NCO to generate any arbitrary frequency from my FPGA board... but was quickly disabused of that notion when trying to generate small offsets generated clicks at that offset. What can be done, however, is to get near the frequency, down convert the signal (with the Tayloe mixer), A/D to get IQ signals, then complex multiply to get to the frequency in question, and finally low pass filter and demodulate.
Must be why Canadian geese are so aggressive.

Jokes aside bet they tasted good.
Users don’t have user agent strings, user agents do.
A lot of comments here are confusing the two use cases for crawling: training and summarization.

Perplexity's utility as an answer engine is RAG (retrieval augmented generation). In response to your question, they search the web, crawl relevant URLs and summarize them. They do include citations in their response to the user, but in practice no one clicks through on the tiny (1), (2) links to go to the source. So if you are one of those sources, you lose out on traffic that you would otherwise get in the old model from say a Google or Bing. When Perplexity crawls your web page in this context, they are hiding their identity according to OP, and there seems to be no way for publishers to opt out of this.

It is possible that when they crawl the web for the second use case -- to collect data for training their model -- they use the right user agent and identify themselves. A publisher may be OK with allowing their data to be crawled for use in training a model, because that use case does not directly "steal" any traffic.
Should there be a difference in treatment between a user going on a website and manually copying the content over to a bot to process vs giving the bot the URL so it does the fetching as well? I've done both (mainly to get summaries or translations) and I know which I generally prefer.

This is the company that had a "recycling mode" that did nothing except brick the hardware, ensuring that the speakers could not be used second hand, then encouraging people to bring the bricked machines to recycling centers who could do nothing with them.

No one should be surprised that Sonos is a scummy company, if you are you only have yourself to blame.

It wasn't standardized before, so it didn't "always work" on any implementation.
So if I get access to the Perplexity AI source code (I borrow it from a friend), read all of it, and reproduce it at some level, then Perplexity will be:" sure, that's fine no harm, no IP theft, no copyright violation, because you read it so we're good"?

No, they would sue me for everything I got, and then some. That's the weird thing about these companies, they are never afraid to use IP law to go after others, but those same laws don't apply to them... because?

Just pay the stupid license and if that makes your business unsustainable then it's not much a business is it?

Tales from the interview: Can you rotate this two-dimensional array?
Disinformation, misinformation, malinformation (whatever that is), and even hate speech are all just censorship in sheep’s clothing. These fact checkers end up being used by the big social media and news organizations as their basis to suppress (censor) information that, at least currently, always seems to favor one side of the political spectrum. Hunter Biden’s laptop was discounted as Russian propaganda in the last election, but was just entered in to evidence by the DOJ in his trial as verified and legitimate. Many of the issues around Covid were labeled misinformation and censored at the time only later to be found credible (lab leak, ineffective social distancing, vaccine efficacy, etc.). It has always been up to the people to openly discuss these issues and choose what they find credible. Although one side of the aisle is benefiting from the “misinformation” label currently, pendulums swing and the whole script could flip in the future so it’s in the best interest of both sides to stop this craziness now. There is no such thing as nonpartisan or bipartisan, and these organizations should certainly exercise their 1st amendment right and share their analyses, but when they are used to control the actual flow of information to the people it becomes dangerous and destructive.

Looking at someone’s profile to find something irrelevant to discredit them, like you are doing with the age of my account, is the real Reddit behavior. It really has no logical bearing on the point I am making.

As for the point I’m making: minor incidents that are not newsworthy get upvoted as long as they are unfavorable to Elon Musk. On the other hand, one of the most significant pieces of financial news this year, the reapproval of his pay package from several years ago, did not make the front page and had barely any comments for how significant it is, because many HN users cannot stand to acknowledge anything that is favorable to Elon Musk. This is the type of overly politicized ideological and tribal thinking that should not have a place here.

What pieces are you looking to be stable (and what's your definition of stable)?

Asking because some pieces, like the Collector, aren't technically a stable 1.0 yet, but the bar for stability is extremely high, and in practice it's far more stable than most software out there.

But there are other pieces, such as a language's support for a specific concept, that are truly experimental or even still in-development.

> The second concern, though, is can perplexity do a live web query to my website and present data from my website in a format that the user asks for? Arguing that we should ban this moves into very dangerous territory.

> Everything from ad blockers to reader mode to screen readers do exactly the same thing that Perplexity is doing here, with the only difference being that they tend to be exclusively local

Which is a huge difference. The latter is someone asking for a copy of my content (from someone with a valid license, myself), and manipulating it to display it (not creating new copies, broadly speaking allowed by copyright). The former adds in the criminal step of "and redistributing (modified, but that doesn't matter) versions of it to users without permission".

I mean, I'm all for getting rid of copyright, but I also know that's an incredibly unpopular position to take, and I don't see how this isn't just copyright infringement if you aren't advocating for repealing copyright law all together.
