I don't have kids, so I'm not in the trenches on this one. But a personal anecdote that might serve as evidence that other things are possible to everyone navigating tech and kids...

When I was a kid living in a trailer in the midwest in the eighties I asked my parents to buy me a secondhand set of 1973 Encyclopedia Britannica from our local library - for $7. It fed the same curiosity and joy of discovering new things that you would want your kid to get from resources online.

When we went on trips we always drove. And even if I didn't already have a book or books from the library that I was reading at the time, my parents would suggest I take a volume of the Encyclopedia. And sure enough if I got bored I'd break it out. (Unless it was too dark to read at which point I'd just fall sleep.)

That's all to say there are alternatives that cut the gordian knot, which kids can really dig if you frame it right. My parents were both voracious readers themselves, and it didn't take long for their reading to my sibling and I to turn into reading on our own. So when we got something that provided the novelty and agency of navigating your own way through an encyclopedia, it was a huge hit.

Of course things are very different today. And I'm not a luddite or even someone who believes that old ways are intrinsically better. But there are ways to feed the many various and often contradictory needs kids have that aren't reliant on contemporary tech.

AFAIK, there are several reasons for the increase in autism diagnosis, but a few key ones people forgot about...

1. DSM IV, the old way, had a separate diagnosis for many autism related disorders. Think Asperger's, pdd-nos, etc. When DSM V was released, many separate diagnosis were umbrella'd in to autism spectrum disorder. The old disorders simply disappeared and are not made any more.

2. Getting an Autism Spectrum Disorder diagnosis opens up a huge amount of insurance and educational leeway. You go from qualifying for general therapy to intensive support therapy, classes, and more. At school, with the diagnosis, you get expanded help for kids that are really struggling. So there is a strong will created by parents and educators to try to get that diagnosis. When you are struggling, this extra support can really help everyone, the kids, teachers, and parents.

These two points alone may account for a lot of the increases we are seeing. I don't know why they are never mentioned by media and the skeptics.

>Parents are responsible for their children.

If this is the case, why do we pass any special child protection laws that override what a parent decides is best for their child (and in a way that punishes those involved beyond just the parents)?

As to if any such law is appropriate or not, that would seem to be a question of how much harm is caused and if the law is aimed at preventing the harm. Many things are addictive, but only some of those cause enough harm to justify a ban to protect children.

Skills compound, so the logic of I didn’t do x until age y, and I was still competitive, doesn’t mean that your kid will be competitive with their peers if they wait until the same age, assuming others are not.

Not that it means 2 year olds should run around the internet with unfettered access, but just that the aforementioned logic is not sound.

There is also benefit to being culturally in sync (not necessarily 1 to 1, but somewhat) with one’s peer group. It can be alienating to be the odd one out.

If it were up to my grandparents, I never would have watched a tv show or movie growing up, or read fiction novels. But while that may have had some benefits, it obviously would have some costs with me being unable to participate in some of my peers’ activities and conversations.

At the end of the day, even if we somehow recreate a manufacturing base from scratch, where would we get employees? The labor markets are the tightest they've been in 20+ years and manufacturing jobs rank among the least desirable.

Rounding homeless and drug addicts of the street and putting them to work? Maybe. That doesn't exactly speak to quality products other countries will want to buy.

Taking people en masse off of social security and disability? That might make sense from a financial standpoint, but it would be political suicide.

Makes sense to validate businesses as early and cheaply as possible.

While AI accelerates initial product development, there might be a tail end of costs, like tech debt that plagues a product for years. For startups that die, it won't matter, and startups that "make it" (in VC terms, i.e. jackpots) can afford to rebuild the whole product from scratch.

I kinda went down a rabbit hole a while back with certain treatments that can kill adipocytes, as there's actually some significant research backing both heat-generating and cold-generating treatments. They do kill fat cells, and they are flushed out of the body. But people who undergo such treatments do not lose fat. At best, these devices can reshape your fat, pulling it out of one area and distributing it more evenly in other areas.

The problem is that when you kill an adipocyte, it releases all of its triglycerides, which are then free to move around the blood stream. But when blood triglyceride levels are high and there isn't significant oxidation, other metabolic processes are triggered to start to store them. So you kill an adipocyte, release the triglycerides, which get reabsorbed into still living adipocytes, which now get engorged and then multiply again, replacing the fat cells that have been killed.

After learning quite a bit about these processes, I think these devices might actually be useful, not for losing fat, but by eliminating this sort of fat memory. In other words, they should be used after significant weight loss, because adipocytes are relatively empty and externally triggered apoptosis can kill the cells without releasing significant quantities of triglycerides which can be reabsorbed and trigger adipocyte mitosis. I think this would effectively reset that person to a state as if they had never been fat in the first place. Thoughts?

> The fact that you can't turn it off system wide shows the macOS leadership is asleep at the wheel

You totally can, at least on Apple's XDR displays.

Just go to System Settings -> Displays -> Preset and change it from "Apple XDR Display (P3-1600 nits)" (or whatever) to "Internet & Web (sRGB)". You lose the ability to change screen brightness (I assume because you're locked to reference brightness), but HDR is fully off.

It does not have to be perfect to be better. It's not great that 13% of revoked certificates would still be there (and get trusted by CRL-ignoring clients) but significantly smaller CRL files may get us closer to more widespread CRL checking. The shorter lifetime also reduces the window of time that a revoked certificate can be exploited by that same 87%. While I'd wager most certificates that get revoked are revoked for minor administrative mistakes and so are unlikely to be used in attacks, some revocations are still exploitable, and it's nearly impossible to measure the actual occurrence of such things at Internet scale without concerted effort.

This reminds me a bit of trying to get TLS 1.2 support in browsers before the revelation that the older versions (especially SSL3) were in fact being exploited all the time directly and via downgrading. Since practically nobody complained (out of ignorance) and, at the time, browsers didn't collect metrics and phone home with them (it was a simpler time), there was no evidence of a problem. Until there was massive evidence of a problem because some people bothered to look into and report it. Journalism-driven development shouldn't be the primary way to handle computer security.

There's many factors in play from what your SDR white point is at, how your OS handles HDR video, what the content contains, and finally what your brain is doing.

HDR10(+) & Dolby Vision, for example, encode content at absolute luminance, so they are basically completely trash formats since that's an insane thing to expect (the spec for authoring content in this format literally just goes "lol idk do X if you think it's going to be seen in a movie theater of Y for TV and hope"). Sadly, they are also quite common. Mobile phones (both Android & iOS) are instead pushing HLG, which is better. Although then hilariously MacOS's handling of HLG was atrocious until the latest update which fixed it but only if the video contains a magic flag that iPhone sets, but isn't standard so nobody else sets it (the "avme" tag https://developer.apple.com/documentation/technotes/tn3145-h... )

There's then also just how your eyes & brain react. When HDR shows up and suddenly the white background of a page looks like a dim gray? That's 100% a perceptual illusion. The actual light being emitted didn't change, just your perception of it did. This is a very hard problem to deal with, and it's one that so far the HDR industry as a whole has basically just ignored. But it's why there's a push to artificially limit the HDR range in mixed conditions, eg https://github.com/w3c/csswg-drafts/issues/9074

Because it's actually fairly slow.

Among other things, the OSD was not designed with NVMe drives in mind - which is fair, given how old it is - so it's nowhere close to being able to handle modern NVMe IO throughput and IOPS.

For that you need zero-copy, RDMA etc.

Note that there is a next-generation OSD project called Crimson [0], however it's been a while, and I'm not sure how well it's going. It's based on the awesome Seastar framework [1], backing ScyllaDB.

Achieving such performance would also require many changes to the client (RDMA, etc).

Something like Weka [2] has a much better design for this kind of performance.

The point of Plato's dialogues (whether fictional, based on a real-story or otherwise) is to encourage thought and not to forward a conclusion with the aim to stop thought. I encourage people not to outsource their own thought to Wikipedia (or other sources).

As the comment I was responding to suggested, ostracization is ancient. Ancient enough that it is the topic of one of the most famous dialogues by one of the most famous philosophers.

I will add that the Apology is quite short and freely available online. It is worth the quick read, Then, as I suggested, I encourage people to deeply think about why Socrates chose death (rather than accept quick answers in HN comments).

> Something doesn't add up

The economy moved away from being founded on Marx's C-M-C to firmly being fixated on M-C-M' which in plain English, means "We now use Money to make more Money, leveraging Commodities as an intermediate step. The Money is all that matters, not the social benefit/harm" -- IMO, that helps explain why, even though many people are suffering financially, the market is at an ATH.

China invested their low interest fiscal capacity into developing over decades via coordinated policy of their central bank / industrial strategy nudges to their businesses. China's factory ecosystem and the ability to build stuff meets my definition of a protective moat. Its very hard to replace and one can only contemplate it over relatively long time frames.

US businesses were free to do the same over the past low interest environment, but we did not have the same incentives, not inclinations in terms of prevailing business strategic appetite for factories. In contrast, for big tech, there was interest and appetite for it and significant capability with protective moats were built - but one could argue that software based tech moats may be faster to bypass.

I'm not in any position to judge you or the work you've done. Don't end it though. You are far and away more valuable than lab work or the tantrums of a child-king. If you need someone to reach out to, I'm here. I've been on that precipice, for entirely different reasons, but I imagine the feeling is much the same.

Hang in there.

Interesting to understand what is possible in this Deno/Pyodide environment. For example sklearn works despite being quite an involved dependency [1]. Another side to this is data input/output, which seems possible with a low level interface [2]. Very exciting that (a simple) end-to-end ML experience is now possible in the modern browser.

Though that also comes with male-pattern skeletal growth. So unless your body still has elevated/male-level T levels, you're carrying around a disproportionately heavy skeleton which negates the advantage. If the net effect were actually an advantage, you'd expect the womens' sports which are allowing trans women to be dominated by them, but they really just aren't.

Additionally, trans women on HRT typically have their T suppressed below standard cis women levels, and thus well below the levels of cis women athletes (the top levels in any sport by definition tending to be outliers in performance).

On my home LAN connected with 10gbps fiber between MacBook Pro and server, 10 feet away, I get about 1.5gbps vs the non-network speed of the disks of ~50 gbps. (Bits, not bytes)

I worked this out to the macOS SMB implementation really sucking. I set up a NFS driver and it got about twice as fast but it’s annoying to mount and use, and still far from the disk’s capabilities.

I’ve mostly resorted to abandoning the network (after large expense) and using Thunderbolt and physical transport of the drives.

I spent more than that on a camera lens to take pictures of birds.

I know multiple people in a local astrophotography club who have spent 30x that to take pictures of distant celestial objects for fun.

People have hobbies, and money.

In the case of the 5090 many people are using them to make money, so the price is dictated in no small part by how much money they are able to make using them.

I don’t think it’s an unreasonable title, but it’s also not accurate. The paper states quite clearly that they’ve found reasonable evidence of a known biomarker. They don’t know enough to say whether it’s from a biological or some abiotic process (but speculate a little about what that might mean and what evidence they would need to take that further).

That’s quite a different tone from the article, and I think the comments here and elsewhere online reflect that.

> It doesn't have to be your bank if you don't want,

"If I don't want"? I would get no choice at all about who it would be, because in practice the Web site (or whoever could put pressure on the Web site) would have all of the control over which issuers were or were not acceptable. Don't pretend that actual users would have any meaningful control over anything.

The sites, even as a (almost certainly captured and corrupt) consortium, wouldn't do the work to accept just any potentially trustworthy issuer. In fact they probably wouldn't even do the work to keep track of all the national governments that might issue such credentials. Nor would you get all national governments, all banks, all insurance companies, all cell phone carriers, all neighborhood busibodies, or all of any sufficiently large class of potentially "trustable" issuers to agree to become issuers. At least not without their attaching a whole bunch of unacceptable strings to the deal. What's in it for them, exactly?

Coordinating on certifying authorities is the fatal adoption problem for all systems like that. Even the X.509 CA infrastructure we have only exists because (a) it was set up when there were a lot fewer vested interests, and (b) it's very low effort, because it doesn't actually verify any facts at all about the certificate holder. The idea that you could get around that adoption problem while simultaneously preserving anything like privacy is just silly.

Furthermore, unless you use an attestation protocol that's zero-knowledge in the identity of the certifier, which OpenID is unlikely ever to specify, nor are either issuers or relying parties going to adopt this side of the heat death of the Universe, you as a user are still always giving up some information about your association with something.

Worse, even if you could in fact get such a system adopted, it would be a bad thing. Even if it worked. Even if it were totally zero-knowledge. Infrastructure built for "of adult age" verification will get applied to services that actively should not have such verification. Even more certainly, it will extended and used to discriminate on plenty of other characteristics. That discrimination will be imposed on services by governments and other pressuring entities, regardless of their own views about who they want to exclude.

And some of it will be discrimination you will think is wrong.

It's not a good idea to go around building infrastructure like that even if you can get it adopted and even if it's done "right". Which again no non-zero-knowledge system can claim to be anyway.

Counterproposal: "those types of social media platforms" get zero information about me other than the username I use to log in, which may or may not resemble the username I use anywhere else. Same for every other user. The false "need" to do age verification gets thrown on the trash heap where it belongs.

it's a factual thing I learned after following the comment threads and asking the AI about it, it does link to the source article.

Why is this bad?

I will, im just wondering, would only the link to the source article been better/acceptable here?

I dont' get the hate for AI replies if they're on topic and generated by a human tbh, but ill respect it since its not first time seeing this i guess

Choice of scripting shell is personal preference. Preferences may differ amongst computer owners. For example, I prefer NetBSD sh. On Linux I use a slightly modified Dash.

As for the preferences of others, I note the default scripting shell on the largest Linux distributions is not Bash. It is of course Dash, which is derived from NetBSD sh, which is derived from the Almquist shell (ash). Indeed, ash is a popular choice for scripting. It is smaller and faster than Bash.

The (Open)RTB system makes things more competitive and reduces costs for advertisers by making unsold inventory available to an automated marketplace while also increasing revenue for smaller publishers who otherwise wouldn't have been able to create first party relationships with advertisers. The middlemen are various identity providers and other tracking/data enrichment services, as well as third party exchanges, DSPs and SSPs. Believe it or not this system makes it a lot cheaper than just having someone buy ad space directly on a website

> Three industry studies showed less than 50 cents of every dollar goes to showing ads.

Every penny of what is spent goes to showing ads, by definition. However, that doesn't mean that every penny goes to the publisher. The advertiser may look at the 60 cents being spent on everybody between them and the publisher and say "hey, I'm getting ripped off! I could be paying 4 cents/CPM instead of 10 cents/CPM!" but each middleman (usually) adds some kind of value to increase acquisition rate. For example:

* Identity providers who have lists of user IDs that belong to "high CTR" audiences (users more likely to click ads)

* Geo providers who tell the bidders where the User's location is so that they can target locally-focused advertisements to them

* User intent plugins, "abandoned cart" retargeting, product recommendation providers, etc. who look at user interaction events and build profiles of people who can be retargeted

* Exchanges which conduct auctions across multiple DSPs to get a better price for publishers while also making more inventory available to advertisers

At one company I worked for, we allocated impressions ahead of time. Based on prior years' data and viewer ratings of TV shows, we could predict the future, determining how many viewers a video or TV show would get, and then selling the advertising inventory based on that prediction. That shit ain't free!

All of these things are designed to increase your acquisition rate from x% to y%, where x > y. Sure, you could just pay $5,000 a month to a website to show a banner ad directly, but a larger % of your money would be wasted on users who are utterly uninterested in your banner.

This is happening to me right now. I have run a site for 14 years that gets most of its traffic during the current two week stretch (it's related to NBA playoffs).

All of a sudden, Adsense revenue has gone to basically zero. $90 of earnings from Sunday has even disappeared.

There is no way to contact a real person at Google. You can just post in their dumb little forum and someone with no authority who doesn't even work there will reply to you with the same pointless info from their FAQ.

If things go the way they have been, it seems like roughly $2k in revenue that's been pretty consistent for the last decade is going to be basically zero this year and there's nothing I can do about it.

Thankfully, this is just a side project and I'll be fine, but its not hard to see how they could screw someone over who relied on it.

I’ve been trying to contribute to a Linux kernel subsystem recently. I can program in C, but that’s not really the barrier. Most patches are pretty tiny changes to the C code, I think. At the moment I’m finding that I don’t understand enough about the subsystem and hardware - that is the main obstacle to making meaningful changes. I’m not sure if there will eventually be AI agents that work on the Linux kernel without close supervision, but the “craft of coding” was probably never the most important thing.

Something I heard on a podcast recently re. AI is: do you think computer science, machine learning, embedded systems etc. will become more important to society in a world of advanced AI or less? I think it will become more important, but I suppose that doesn’t necessarily lead to more jobs.

> Don’t panic. Even if tariffs did cause the iPhone’s price to surge, we would have plenty of cheaper options, like buying last year’s phone model instead of the latest and greatest.

Sort of like all those cheap used cars we could buy during the COVID supply chain disruption...?

I'm on board for the overall gist of the article (recycling old tech is very viable for most people these days), but the framing of this message around tariffs making new tech much more expensive just seems to ignore basic supply and demand factors which would pretty obviously drastically increase the prices of used tech.

>he problem of american politics, over the last decade or two, has been the complete cultural maginalisation of the right (from centres of civil power). Something had to give. The universities, the corporate culture, the internet mass media -- had all been monpolised by a "consensus moralism" which was replusive to a lot of people.

Can you elaborate on this?
