I doubt it would be as cohesive as what Apple would do - they are paying legions of top designers to think about every pixel. If it comes super well designed out of the box I appreciate it but I don't care enough to bother tweaking anything. I've tried various plug-ins in Gnome but all pretty amateur compared to what Apple is doing. Of course, I'll stick to Linux as I want to develop in the same environment that my code will be running in production. The other aspects matter far less to me.

That's a jurisdiction problem, not a technology problem. No tech is foolproof, but even with the current technology someone would be much safer (for others, too) in the back seat than trying to drive tired, borderline DUI at night in unfamiliar town. Which many folks regularly do, for example on business travel.

The reason I cannot do this today is laws, not technology. My 2c.

I get that your point is that we don’t have a strong intuition for lenses and that’s tied to a lack of evolutionary reason to have them. I agree and suspect that might be the point of why Apple are using a the lens effects. We don’t need to go so far as to say the natural world is completely devoid of such phenomena. Of course they’re there but they’re largely not relevant to survival throughout human history

The F-35A is only like 40% more expensive per-unit than the Gripen and is arguably at least 40% more capable (the payload alone beats that). It's true that the development program was a boondoggle (though Saab isn't completely clean here either), but that cost isn't for the most part borne by the export customers.

Economy of scale continues to rule all, basically, and there are already 3x as many Money-Gobbling Monstrosities in the air as there are Gripens.

May I suggest finding a local chapter of the public speaking group: Toastmasters.org? The different clubs will have different personalities. So you may need to check out a few. The basic concept is you will eventually perform ten speeches and develop your communication skills and get feedback along the way. You can also sign up for an officer position and develop your skills in that area. You may also want to compare soft skills with executive skills. Both are important. For fun, my wife and ai enrolled in a Fred Pryor online program. $99/yr and it was an all you can eat buffet of soft skills classes. A weeklong conference in soft skills may scratch an itch but not go deep enough with “homework problems” to really develop you.

You guys have misunderstood in my opinion what he is saying actually.

What he means to say is. He I have a need and I am ready to contact the moderator so that he can allow me to DM a particular guy.

He might be even willing to pay some money depending on his bed to contact.

So if HN could create a paid service where genuine users would pay some amount to the HN and then a paid moderator would tap on the shoulder of the target guy and say hey this dude is interested to DM you and this is his message. If you want to chat back then you can DM him back otherwise peace out!

Yes it's not a puritanic of being a free forum but puritanism has solved not many problems.

Also without payment this system will not work. If u need it u gotta pay

I can't either.

Having implemented this, I'll claim that this is already competitive for needles as small as 2 bytes, and if the needle doesn't show up in the first couple “vector sizes” of the haystack.

Also, look at burntsushi's comment. They use this algorithm for similarly small sizes. They do use Rabin-Karp for “supremely short haystacks” (just because that lib is awesome and uses every trick in the book), but that wording should give you an idea of how small the threshold will be.

And really, how common are “supremely small” haystacks?

What our "system" seems to actually incentivize is keeping people chronically ill so that they're forced to continually pay for their non-treatment.

It's hard not to be incredibly cynical in the face of things like this. Way more than once have I thought "this is a cruel and unusual punishment" -- wait aren't those prohibited?? Oh right we get around that by making cruelty usual.
Ask HN: How do you teach your kids about AI?
by markun | 2025-06-14 14:12:29+00:00
I'm a father of two kids (9 and 11) and I’ve been struggling with how to introduce them to the world of AI — not just the tools, but the concepts, limitations, risks and wonders.

As a way to process this challenge, I’m working on a children's book that explains AI in a narrative format. I’ve written other books for kids tackling complex topics like politics, grief and digital privacy — but this one feels especially urgent and slippery.

In the story I’m outlining, a child receives a plain cardboard box as a gift. Curious, she starts stuffing all her books into it — stories, encyclopedias, comic books, math manuals. At some mysterious threshold, the box "comes alive" and starts responding. As they interact, the story explores concepts like hallucination (the box starts making stuff up), reinforcement learning (the box improves when rewarded), bias, prediction, and the fine line between intelligence and mimicry.

I'm looking for:

Good learning resources, metaphors or visual models that help explain how AI works (ideally in ways accessible to children)

Reflections on when and how to introduce AI to kids — especially before they get too deep into GenAI tools without critical thinking

Stories or experiences from others trying to teach (or explain) AI to younger people, whether as parents, educators or creators

Would love to hear thoughts, resources, or warnings. Thanks!

When being a SysAdmin wasn't a viable option anymore, I ended up making gears, and gear like objects (such as vanes for water meters) in a Gear cutting job shop. The pay and commute were horrible, but I know some, if not most, of those gears will still be in use in the year 2100, long after I'm gone.

I think there is something in that. Certainly the world of work does seem to pivot between rewarding people that “do the work” and those that “do the work around the work” but separate themselves from actual execution. 2021-2 was peak middle manager froth, and were on a swing toward more operator led now. Usually middle management “present the work upwards” types dominate though.

If private industry were the military, most companies would be headed by O5 or O6; the scope of duties and responsibilities of an eg VP or CFO are actually quite comparable to a lt colonel or navy commander, CEOs are fairly like captains & colonels. These ranks are enough to head a large ship, air base, or training facility with hundreds or thousands under their command. Only extremely large companies (50k+ employees) have anything with a role comparable to admirals or generals.

I did a little poking round and I think the modern equivalent to old super computers is a mainframe. Modern super computers take up entire warehouses, cost upwards of $100 million, and are measured in exaflops.

Cray 1 costs US$7.9 million in 1977 (equivalent to $41 million in 2024) (Source: Wikipedia)

I have no idea what IBM z-series mainframes cost but I think it would be less.

$41 million can buy you one or more thousands of rack-mounted servers and the associated networking hardware.

My rough guess would be the difference in 2024 iphones to mainframes is an order of magnitude more between them than Cray and anything else on the market at the time.

It’s also interesting to note how much software has changed. The actual machine code may be less optimized, but we have better algorithms and we have the option of using vast amounts of memory and disk to save cpu time. And that’s before we get into specialized hardware.

> focus on content

This has been Alan Dye's modus operandi since he took the helm on software design and the problem is it does not scale to larger devices. On a phone and mostly on an iPad, where you're far more likely to be consuming content anyway, it's not the worst thing to shoot for.

On a Mac it's infuriating. I'm working on anywhere from a 14" to a 27" display, both have a wealth of pixels to work with: why are you hiding controls? You're not making anything simpler, I need those buttons to perform the tasks I'm trying to do. All you've done is make it less intuitive, less discoverable, and added extra clicks.

To be honest it has some problems even on the smaller devices too, mainly in the form of lack of visual affordances. So much functionality you would never discover unless you'd seen someone else do it or triggered it by accident (and even then might not realise what you've done—just yesterday I had to help my mother get out of private browsing in Safari because she'd swiped across to it and didn't know how to get back).

There is so much that I love about this article that it makes me shy.

This image: “Gnossienne #1” radiates a mood of … what, exactly? Lightly anxious contemplation? Oddly contented melancholy? An icy but heartwarming breeze? ...Slightly bruised, but not down and out.

This sentence: In some ways, Satie feels like a long-ago ornament; at the same time, more playfully modern than our own increasingly doctrinaire era.

These recommendations: Dip a toe into the Satie rock pool and you soon discover a cove, a coastline, an entire horizon. As well as his solo-piano works, he wrote a riotous avant-pop ballet (Parade); a comical Christian allegory (Uspud); an intimate drama with samplings of Greek philosophy (Socrate); and his final work was a groundbreaking movie soundtrack (Cinema).

This reference: There is copious testimony as to the utter shambles of his living space — yet the moment he steps outside this tiny cell he is a smiling dandy, spick and span, his own ambulant branch of Yohji Yamamoto.

Just, great.

It's not the only market they've cornered.

If you are paying for a VPN, the odds are good that it's owned by Kape Technologies, another Israeli company staffed by former Unit 8200 personnel. PIA and a bunch of others are now under their purview.

They'll say they don't keep logs, but only an idiot would trust that.

Cellebrite also does questionable shit with phone forensics; newer products upload phone images to "the cloud." Supposedly it is instanced and law enforcement is just supposed to trust that yet another function the Justice Department outsources to Israel isn't backdoored by them, like Inslaw/PROMIS.

We do use clangd and it provides many checks, but I wanted to include clang-tidy in the CI. Though since me and my colleagues combine ff-only and ‘must build successfully before merging’, adding like 5 minutes to the CI is really annoying.

Iirc the reason why clangd is so much faster than clang-tidy is that clangs omits certain checks and limits which code it analyzes.

> It also makes me think about how much untapped potential might be hiding in the ordinary plants we pass by every day.

A ton, which is one selfish reason the genetic diversity collapse is such a negative. In this particular discovery, we already knew there was something interesting about the morning glory plant and it took us decades and decades to find it. To give you an idea how little plant life has been studied, we have sequenced the gnome of less than one thousand species.

This kind of problem could be made a lot more straightforward if we separate the schema owner (i.e., the business) from the rest of the stack. Some major SQL engines have this role built-in. Whatever you want to call it - "premature" optimization, etc. - the act of simultaneously trying to optimize while you build is perhaps important, but otherwise very disruptive to the creative exercise of naming things and relating them together (domain modeling).

When your brain is constantly locked into big-O notation and you are only worrying about N being larger than a billion, it becomes really easy to justify running a high quality representation of the domain into the dirt over arbitrary performance concerns. E.g., storing a bunch of tiny fields in one JSON blob column is going to be faster for many cases, but it totally screws up downstream use cases by making custom views of the data more expensive. The query of concern might only hit once a day, but the developers probably aren't thinking at that level of detail.

The really tragic part is that the modern RDBMS is typically capable of figuring out acceptable query plans even given the most pathetically naive domain models. I think in general there is a severe (and growing) misunderstanding regarding what something like MSSQL/Oracle/DB2 can accomplish - even in an enterprise as large as Netflix.
Ask HN: Future of Learning and Personal/Professional Development?
by squircle | 2025-06-14 14:18:24+00:00
Assuming the desirable purpose of education is to ennoble fully realized individuals (maximum agency and autonomy?), is it possible the internet could be used to both quantify and qualify individuals aptitudes, skills, and abilities without placing an enormous economic burden (effectively indentured servitude) on individuals and families? My gut says the result would be a veritable and perpetual renaissance (but I'm also high on coffee bean and simply wondering what to do with my own personal volitional energy at this point in my life.)

Edit: Perhaps the larger question is, if we had a mechanism and perspective available that would uproot/replace parasitic or otherwise harmful social institutions, how might cobra problems (people not wanting to lose what they've earned through effort, hard work/dedication, and experience, or dogmatic beliefs ultimately rooted in fear) be resolved?

You can't compute the exact result of a quantum measurement. Now, randomness is a somewhat separate concept from computation. But still, a Turing Machine can't predict how a quantum system will behave after a measurement, so in some sense it's not computable. The best you can do is to compute the wavefunction and the resulting probabilities of the various possibilities.

This is stunning. An outstanding write up and accomplishment!!

Coming from react web applications it appears to me that threejs, r3f, r3d and shaders provide a order-of-magnitude better user experience than react. There are certainly facets of a web site that work better with react just as there are facets that would be much better with 3jsrfd. I do not understand personally, why we are not using both (appropriately).

And yes, there is the problem of SEO with 3jsrfd, but with AI now on the scene maybe that is not such a bad thing. And if we only had a business model that did not require SEO ....

For all his faults, Jobs always sold the idea that he really thought the stuff he was showing was the coolest thing ever. There was at the very least an illusion of pride and excitement, even if it wasn't always genuine. He'd crack jokes, make off-hand remarks, and wasn't afraid to mention competitor's products.

Modern Apple presentations are just like being read some marketing materials. It's very disingenuous.

As a pro-nuclear-power fan, this does sound like it could be good news. I do have a few concerns.

First, the power source is orthogonal to AI. Datacenters will run just as well on nuclear, or coal, or wind and solar. And the electricity generated from nuclear could be used to run datacenters, or power electric cars, or replace decommissioned coal plants. In this context, the AI stuff is just confusing matters.

Second, this administration is about the last people I'd want involved in assessing or enforcing precautions around nuclear safety.

> However honey isn't a trivial component to produce

And you think grapes are?

We were probably farming honey long before we were farming grapes.

> I suspect they added in honey as a source of sugar for fermentation. Honey is a pretty common component of making fermented drinks (mead being a well known one). So this sounds like a natural coupling to me.

They definitely knew about mead. Pliny the Elder (one of the article's sources lol) even talks about mead (Hydromeli/Hidromel), and observes "it is nowhere more highly esteemed than in Phrygia (Turkey)". He also points out honey is sometimes added to "artifical wines", which seem to be just ancient-roman talk for foreigner-booze.

Frontline medicine is all about “just do x” hacks to try to move quicker. We turn people into a fault tree, and enforce that with EMR and audit/review you create a bias to focus on the 80/20 approach. Essentially turning medicine into a helpdesk.

A family member ran into this with a brain tumor, which for a patient presenting with a headache is a 1% likelihood. Slightly elevated blood pressure was the focus in that case. Persistence and a subtle symptom changed triggered the CT scan that ultimately led to the diagnosis about 8 weeks later. Unfortunately with melanoma, 8 weeks is a long time.

Ultimately there’s no right answer. 99% of people with headaches have high blood pressure or other “normal” causes. Sending 1,000 people to CT to identify 5 tumors will cause 50 other complications.

Think of doctors like a helpdesk in a big company. Open a ticket, but work your network to get someone who isn’t dumb to think about it. If you’re too poor or don’t have friends and advocates, your outcome will be no mas.

Good luck. This is not new. Back in the Enterprise OOP era, there was a fad of developing universal data entities. Everyone eventually learned that there is no such thing as a universal entity. The semantic meaning of the data model depends on the user context, not the producer context. A "Movie" is not the same thing to the Finance team, Acquisition team, Infrastructure team, or Customer. There is not even always a common identifier, let alone common fields, let alone common meaning of the fields.

I am not sure what the question here actually is -- the title compares apples to oranges (e.g. Obsidian uses YAML for meta-data but markdown is the markup language). Then in the post itself, it sounds like you ask a question about how to organize your note storage. Separate questions with some potential overlap.

A couple of questions -- what didn't you like about Obsidian? Have you considered Emacs and Org-mode?

They DO take the same care if not more care, the problem is that just like with copyrighted content stuff slips through because stochastic text generation is impossible to control 100%.

I've had the most innocuous queries trigger it to switch into crisis-counseling mode and give me numbers for help lines. Indeed, in the original NYT article it mentions that this man's final interactions with ChatGPT did trigger ChatGPT to offer the same mental health resources:

First of all, how would they talk to it? You'd have to give them an RPI5 with serial console enabled, and strict instructions not to exceed the 3.3 volt limits of the I/O. Now it's reasonable that you could generate NTSC video out of it, so they could see on the screen any output.

When you then explained it was just bit-banging said NTSC output, they'd be amazed even more.

Isn't there already a system in place for that sort of thing. I know a couple civilian experts who worked as consultants in iraq (think like water treatment plant engineers) who were given "effective" officer ranks to smooth out interactions with the military members they worked with directly, clarify who they could and couldn't tell what to do. But they didn't wear uniforms, weren't saluted, weren't considered members of the military for most purposes, are not counted as veterans, etc.

If it were simply that, this is a problem the military has run into before and has solutions to it. This is something else: at best weird propaganda at worst I don't really know.

Comparing against a raspberry pi 5 is kind of overkill. While a Pico 2 is close to computationally equivalent to a cray 1 now (version 2 added hardware floating point), the cray still has substantially more memory - almost 9MB vs 520k.

For parity, you have to move up to a raspberry pi zero 2, which costs $15 and uses about 2W of powerm

A million times cheaper than a cray in 2025 dollars and quite a bit more capable.

Reminds me of my experience trying to understand what SAP actually is. For decades I wondered what sort of magic tech must be in there that allowed their software to be used by thousands of different businesses. Then someone who knew about SAP told me: "oh, no that's not how it works -- what they do is have a fixed schema and tell the customer that they must adopt it".

sometimes grug go too early and get abstractions wrong, so grug bias towards waiting

big brain developers often not like this at all and invent many abstractions start of project

grug tempted to reach for club and yell "big brain no maintain code! big brain move on next architecture committee leave code for grug deal with!"

but grug learn control passions, major difference between grug and animal

instead grug try to limit damage of big brain developer early in project by giving them thing like UML diagram (not hurt code, probably throw away anyway) or by demanding working demo tomorrow

working demo especially good trick: force big brain make something to actually work to talk about and code to look at that do thing, will help big brain see reality on ground more quickly

remember! big brain have big brain! need only be harness for good and not in service of spirit complexity demon on accident, many times seen

No, though I know that it's probably quite high. I don't really see an issue with corporate sponsored contributions even if they're specifically designed to benefit those corporations and their customers.

The issue as I see it is if corporations start having undue influence on the direction that Linux takes i.e. not merely affecting their own contributions, but preventing others from contributing. (c.f. Oracle sticking with ZFS CDDL licensing)

I would actually prefer more corporate sponsored contributions as I've just been battling with trying to get the Dell perccli working on Ubuntu 24.04 so that I can administer newly added disks without having to reboot and access the PERC interface during boot (somewhat difficult to do remotely). I was able to install the tool after battling through Dell's website, but it doesn't work properly and declares that two new disks are already in use, despite their status showing as UGood.
