The actual issue is not with 6PPD itself, but when it oxidises to quinones. That transformation was only recognised in 2020, which is why people are only starting to measure and quantify its effects.

It's definitely an issue with ICE and EVs, but is often brought up in EV discussions as people get the impression that EVs are "pollution free" due to their lack of exhaust emissions. Also, EVs tend to produce more tyre dust due to their slightly heavier weight and increased torque.

Incidentally, a small Chinese study found 6PPD and 6PPDQ in human urine in low concentrations. We don't currently know what health effects, if any that may have.

All physical systems have "intrinsic properties" and "measure properties".

Eg., coffee has some internal kinetic energy in the motion of its molecules, and it has the disposition to cause a thermometer to rise its mercury to a certain height.

There's always an open question in these cases: is the height of the mercury a "reliable stand-in" for the temperature of the system? In many case: NO. If you read-off the height too quickly, you'll report the wrong temperature.

No system's intrinsic properties is, litearlly, just its measure properties. We are not literally our behaviours. An LLM is not literally its input/output tokens.

The question arises: what is the actual intrinsic property which gives rise to the measured properties?

it's very easy to see why people believe that the LLM case is parallel to the human case, becuse in ordinary circumstances, our linguistic behvaviours are "reliable measures" of our mental states. So we apply the same perception to LLMs: so to must they generate outputs in the way we do, they must "Reason".

However, there are many much more plausible explanations of how LLMs work that do not resort to giving them mental capacities. And so what's left to those in possession of such better explanations is to try to explain to others why you cannot just put a thermometer into a xbox cd drive and think you're measuring how hot the player is.

Twitter is once again worth $44 billion which arguably was an inflated price at the time of purchase. Tesla is a trillion dollar company. xAI is reportedly at $120 billion.

Idk man, big picture, I see nothing, but success with the media focusing on just the speed bumps along the way

On top of the things that we have zero control over, that do have an impact on our lives. DEI outrage killed a Girls in Tech summer program at our local children's museum. Similar cuts killed a lot of kids summer programs at our local library. Fewer summer programs at the public library and other institutions means thousands of extra dollars in extra camps we have to find and pay for over the summer so that we can sort of work during the day, between drop-offs and pick-ups.

Up front: This is not legal advice.

RF/EMC: definitely. It's an intentional radiator (WiFi) and an unintentional radiator (high-frequency CPU). Using pre-certified COTS modules helps with this quite a bit because they'll, hopefully, pass on their own but they do not relieve you of the certification burden.

Safety: from a legal perspective I don't believe safety certification is mandatory because it runs on low voltage. The wall wart would need to be certified. But... from a liability perspective it might still be necessary. If one of these devices were to catch fire and burn someone's house down the company is going to get sued. Maybe sued by the homeowner, maybe sued by the homeowner's insurance company. The counter to that is to have solid product liability insurance and the insurer may have specific safety certification requirements before they'll even issue an insurance contract, and they may have additional safety certification options that would reduce the premiums.

Satoshi spent real resources to mine, yes they were negligible at the time, but it was real resources. I recall genesis block took 6 days of hashing at difficulty 1. Vitalik just hit print.

BitAxe is a toy, yes. But my point was that people are mining sats. You just don’t see the value in the hardware and energy outlay for integrity. That’s the disconnect. PoS has no real world binding, and so must rely on humans for integrity. Bitcoin… offers an alternative. ETH PoS is more of the same. I don’t trust humans, you trust them too much.

There is a great netflix documentary made in 2018 called "the long road to war". By the time the shooting happened a lot of other pieces had fallen into place. Basically, there were people in military circles and in the government that dictated the geoplitics game based on which country has leverage, who has the train tracks or a port to handle the logistics of war, and there was a certain zeitgeist, an egregore if you will, and things were ripe for conflict.

Yes. And in my view the concept of expectation plays I think a vital role in how an individual relates to society.

If the individual expects that society doesn't care about the individual than the individual has no / less reason to take care of oneself for the benefit of society.

A solution to this is to be more conscious of one's own values. What do you value for how strangers who are nearby you should be treated? Kindly? Aggressively? If those values are being met and are shared by your immediate society, then it's a chance that you might also feel like you are being taken care of. Which then might meet your sense of stress and satisfaction which might then allow you to feel comfortable interacting with society in a playful manner more comfortably bringing up your own needs in the group, and having a shoulder to cry on when when you need to, and having a group just help step in and take care of some of your needs because they have the bandwidth to do so. And they also care because they share your values.

Values are, I think, an underappreciated concept, these days, partly because of all sides shaming, but also because the algorithm as they call it is what is supplanting our values. The algorithm is pushing views on us. And you know the old saying, you are what you eat, that also applies to you are what you read.. we're undergoing conditioning by reading all this stuff about all these different ideas about all these different things which we were supposed to care about. So our values are becoming a little soft and squishy, about what it is that we want or need. We are trying to get what we need from a environment which is being driven by the algorithm and its values.

So anyhow, pay attention to your values... And shape your interactions with the world including social media based on those values. And you'll be happier.

It depends on the application.

Things can get tricky with applications that are installed with WinGet but come with mechanisms to update themselves. If this self-update skips adjusting the right knobs and values in the registry, WinGet will assume that the application is still on the initial version.

For example, this is the case with Obsidian.

Yes, already done. Also found the e-mail of their legal/compliance team and e-mailed them.

Wanted to let this group know because this sort of thing is an appropriately sensitive topic in this community, which is also directly their target audience. The AI agent did not identify itself as an AI agent until I asked, which likely violates other laws as well.

Misunderstanding, I asked him that exact question which was "Why are you working when you could be doing anything you want?" and his response was that he was doing what he wanted. It was a conscious choice. I've mentioned this before but I joined Sun Microsystems the Monday after they had gone public on Friday. As a result I had a unique opportunity to become acquainted with a large number of people > 1000 who had become suddenly wealthy. The observation was that some of them wanted "big things" and some of them wanted "small things." It seems to be an individual preference thing. But mostly people didn't become 'asshole rich people'[1], the majority went off to do the thing they enjoyed doing. One of my co-workers left Sun, paid off their house, and spent their time doing hobby robotics stuff. If you're a curious person with average or better intelligence, working is much more preferable to being bored. That was Guido's complaint, he could do what ever he wanted but he was bored, and one thing "work" does is supply a bunch of things to do.

[1] Some did of course and the contrast was super stark, why live your life antagonizing those less fortunate than you? It's a choice but I never felt it was a healthy one.

I worked with an open-source project that uses Tauri 1.x and their migration has been blocked with issues for months. It was a nightmare for the span I was involved in, and it looks like it hasn't moved forward since I stopped.

In particular, rendering and crashing issues specific to Linux have been blockers, but Tauri 1.x also has other rendering issues on Linux that 2.0 fixed. There's little to no guidance on what's causing the stability and new rendering problems or how to fix them.

The app I worked on was a launcher that installed and managed content for an app, and the launcher invoked the app through command-line flags. Those flags arbitrarily fail to be passed in Tauri 1.x but work as expected in Tauri 2.x, but nobody we asked about it knows why.

They pretty much did say “not the other way around” with

“If these offerings were so great wouldn't we all be clamoring for it?”

The entire question is flawed. It’s a rhetorical question and the implication is “these offerings are not so great and we aren’t clamoring for it”.

I’d argue we are clamoring for it, and we have a lot of options here and they are all great options.

But since the rhetorical question is flawed you now have nothing to anchor on to know exactly what OP meant because if they are flawed here that means whatever they meant in the first half of the comment is also likely flawed.

Maybe you’re not as good at reading between the lines, or the line in general, as much as you think you are and you’re actually the LCD that would be served by a deeper comment.

The whole point of the comment is that it is “telling” of something but the commenter at this point could come back and basically go in any direction. That’s an indication the comment is not saying enough…

The article attempts to explain the difference between "colors" perceived by human eye, vs. wavelengths and signals received by artificial and scientific instruments.

"How much" isn't a question that makes sense, unless you are looking at a specific set of images. Astronomical images can be generated in many, many ways from all sorts of processes. Sometimes there is natural color included, but enhanced; sometimes a wider spectrum is mapped into visible colors so humans can appreciate it; sometimes, the colors are codes for different features, and there is a key provided, so that the colors can be interpreted to what they mean, rather than corresponding to visible light.

It's not just astronomical images, but all disciplines of science use color keys to depict things that are not colors. Look at a topographical map, and it may have green and brown areas that are simply abstracts. A political map uses 5-6 colors to highlight the shapes states or nations, but these are not "real" colors either. But usually, you're provided a color key, for interpretation.

It's arguably not "negotiation", but if the connector is USB-C on both ends, then even 5V requires a couple of resistors to determine which side is the source and which side is the sink.

It's pretty common for really cheap electronics to skip these resistors, and then they can only be powered with a USB-A to USB-C cable, not C-to-C. (Because USB-A ports always a source and never a sink.) Adafruit even makes a $4.50 adapter to fix the issue.

But you're right that everything higher than 5V & 3A gets significantly more complex.

That payment providers label certain projects as "high-risk"*, and will refuse to allow you to use their platform. For example, supplements. Stripe and PayPal will close your account. You're left with providers like CCBill, which require a $1,450 fee to setup Visa and Mastercard.

So, always read the terms of service of platforms you intend to integrate into your projects. And do it before you spend weeks or months developing the project :').

* - High risk involves dating, supplements, CBD, and various other things.

Some famous programmer once wrote about how links should last forever.

He advocated for /foo/bar with no extension. He was right about not using /foo/bar.php because the implementation might change.

But he was wrong, it should be /foo/bar.html because the end-result will always be HTML when it's served by a browser, whether it's generated by PHP, Node.js or by hand.

It's pointless to prepare for some hypothetical new browser that uses an alternate language other than HTML and that doesn't use HTML.

Just use .html for your pages and stop worrying about how to correctly convert foo.md to foo/index.html and configure nginx accordingly.

From the FAQ:

> Each time the Leta application is restarted (due to an upgrade, or new version) server side, a new secret hash is generated, meaning that all previous search queries are no longer visible to Leta.

If I read this correctly, the cached data is per-instance, there would be no way to share cached data among instances if each one has its own secret hash and they are cycled on each start.

The mean density of the interior is much much much lower than you think, because the Schwarzschild interior volume is enormously larger than that of a closed Euclidean 3-ball of the Schwarzschild radius.

Some details:

Christodoulou & Rovelli 2014 showed that the maximal interior volume of a Schwarzschild black hole increases with time <https://arxiv.org/abs/1411.2854>. There is plenty of follow-on work in the literature for other varieties of black hole, and it is pretty generic that a black hole gets REALLY BIG inside as it gets older.

I have previously aimed HNers at DiNunno & Matzner 2008 <https://arxiv.org/abs/0801.1734> (this is also good teaching material for thinking about different systems of coordinates on a Schwarzschild BH spacetime).

One might get some intuition by thinking about pouring material into a (non-static) black hole. When do you saturate the black hole? Does it ever fill completely up? How does its outer boundary (the horizon) evolve as you pour more and more material in?

I would imagine that he made the act of praying to be noticeable to others to act as a protest (e.g. typical head bowed and hands together). If he was simply standing there and minding his own business, then I can't see why there would have been any issue. The idea is that people should be allowed to make use of the health services without feeling undue pressure from others - it's typically a very difficult time for the people involved.

You'd think the whole "LLMs can't reason in concepts" meme would've died already. LLMs are literally concepts incarnate, this has already been demonstrated experimentally in many ways, not limited to figuring out how to identify and suppress or amplify specific concepts during inference.

Article also repeats some weird arguments that are superficially true, but don't stand to scrutiny. That Naur thing, which is a meme at this point, is often repeated as somehow insightful in the real world - yet what's forgotten is another fundamental, practical rule of software engineering: any nontrivial program quickly exceeds any one's ability to hold a full theory of it in their head; we almost never work with proper program theory; programming languages, techniques, methodologies and tools all evolve towards enabling people to work better without understanding most of the code. We actually share the same limitations as LLMs here, we're just better at managing it because we don't have to wait for anyone to let us do another inference loop so we can take a different perspective.

Etc.

Sure, they're a reification of some aspect of meaning. The question is: which aspect(s), and which not.

It is also the case that animals do not "reliably and univerally" implement all aspects of all meanings they are acquainted with, so we aren't looking for 100% of capacities, 100% of the time.

Nevertheless, LLMs are only implementing a limited aspect of meaning: mostly association and "some extension". And with this, plus everything ever written, they can narrowly appear to implement much more.

Let's be clear though, when we say "implement" we mean that an answer arises from a prompt for a very specific reason: because the answer is meant by the system in the relevant way. In this sense, LLMs can mean any association, perhaps they can mean a few extensions, but they cannot mean anything else.

Whenver an LLM appears to partake in more aspects of meaning it is only cheating: it is using familiarity with families of associations to overcome its disabilities.

Like the idiot savant who appears to know all hollywood starlets, but is discovered eventually, not to realise they are all film stars. We routinely discover these disabilities in LLMs, when they attempt to engage in reasoning beyond these (formally,) narrow contexts of use.

Agentic AI is a very good "on steroids" version of this. Just try to use windsurf, and the brittle edges of this trick appear quickly. It's "reasononing" whenver it seems to work, and "hallucination" when not -- but of course, it just never was reasoning.

I'm all for an internet of consent, but it doesn't have to be binary. Cryptography allows things like "Let the developer know the statistics of how their app is being used, but not the details of any particular user". I'm not a guru on this, but think it's a great direction to go.

Probably, but it keeps my dependencies low and packages are automatically updated with backported security patches. So far it has never been an issue, but there has been frustrations when the features aren't available, because the Debian packages aren't the newest versions.

I wouldn't recommend it for something with hundreds of dependencies, but I also wouldn't recommend having hundreds of dependencies.

Poetry has messed up packages more often apt ever did, in my use cases. So far using apt as by package manager has failed me exactly zero times.

> Which made it easier for Republicans to continue to go after public education. They've been pushing for the voucher system for decades as a backdoor way to dismantle the public school system, reasons for wanting to do so vary but it all converges on this point.

in practice, republicans are perfectly happy with public schools when the schools are are "good enough" for their kids. so this caricature seems incorrect. there's a lot wrong with USA public schools, so something must be done. some very not-for-profit voucher schools have been doing excellent work where the public school systens have utterly failed, for example green dot animo in inglewood, or, dramatically, green dot locke in watts.

what is not a caricature: the vast majority of policymakers who want to keep status quo in the public school system send their kids to private schools.

The promise of Electron is the version of chrome you develop on is the version that ships with your app. If it looks right on your machine, it looks right on whoever is running it. This is much nicer than when doing web development and deciding which browsers/browser versions to test and support.

Tauri does not bundle chrome with your app. This makes the bundle size much smaller. But the tradeoff is you end up rendering in whatever the default web view browser is. On Mac this will be some version of Safari (depending on MacOS version), and on Windows it will be some recent-ish Edge thing. Tauri actually has a nice page breaking this down: https://v2.tauri.app/reference/webview-versions/

This also means that a new OS release can change how your app is rendering, so a user can conceivably have a UI bug appear without updating your app.

I'm sympathetic but I find it surprising that people expect rich discourse on microblogging sites like BlueSky, et. al.

There is probably an inverse relationship between number of voices on a platform and how nuanced the discourse can be. Podcasts kind of take this further by isolating the conversation to a few people who can dig deep.

Doesn't make every Tweet toxic and every podcast deep, but there's a tradeoff nonetheless.
