I don't want to start a debate about a specific vendor but the cost was very high. Leaky serialization of call arguments and results, then hairpinning messages across the internet and back to get to workers. 200ms overhead for a no-op call. There was some observability benefit but it didn't allow for debugger access and had its own special way of packaging code so net add of complexity there too. That's not getting into the induced complexity caused by adding a bunch of RPC boundaries to fit their execution model. All that and using the thing effectively still requires understanding their runtime model. I understand the motivation, but not the technical approach.

The difference between the two is that it’s clear that 123456789 can’t be prime since the sum of the digits is a multiple of 3, which doesn’t even require finding the sum since we know 1+8, 2+7 up to 4+5 are multiples of 3. I can even tell you that 43717421 isn’t prime without having to do a divisibility test on it by looking at the digits, although it is a bit more tedious than the 123456789 field.

I'm very sorry to hear your story, and I'm really glad the medication has worked well for you and your family. It's early days, but it seems to be working well for ours too.

I also really admire the way you're dealing patiently with everyone in this thread arguing in bad faith, you have a lot more tolerance than I do! Hopefully it's not getting to you. Best wishes.

`wgpu` in Rust is an excellent middle ground, matching the abstraction level of WebGPU. More capable than OpenGL, but you don’t have to deal with things like resource barriers and layout transitions.

The reason you don’t is that it does an amount of bookkeeping for you at runtime, only supports using a single, general queue per device, and several other limitations that only matter when you want to max out the capabilities of the hardware.

Vulkan is miserable, but several things are improved by using a few extensions supported by almost all relevant vendors. The misery mostly pays off, but there are a couple of cases where the API asks you for a lot of detail which all major drivers then happily go ahead ignore completely.

These rulings only affect third-party apps, not AirDrop. Apple is not required to stop using AWDL for system apps, and is also not required to allow third-party implementations of the AirDrop protocol. They are however required to implement a mechanism allowing competing solutions to automatically trigger a prompt to install their own iOS apps, but the deadline for that isn't until next year and they have not yet shipped it.

1) You can't `npm install` it, which is a huge barrier to entry to the modern breed of "engineers".

2) Companies will happily pay thousands in recurring fees for the built-in NAT gateway, but if an engineer asks for even half that as a one-off sum to motivate them to learn Linux networking/firewalling, they'd get a hard no, so why should they bother?

I both agree and disagree. The issue is not independent thinking and research - it’s the low media literacy of the average person that makes them vulnerable to frauds, grifters, and crazies.

With that said, the first few search results for the query were from the journal Nature, the NIH, and Harvard university. Hardly the loony or malicious caricature that you attempt to paint.

Also, even the proposed effect is modest:

> But early friendship bonds played an even bigger part than maternal relationships in the ways people navigated adult friendships and romantic partnerships, accounting for 4 percent of the variance in adults’ romantic partner- and best friend-specific attachment anxiety, and 10 to 11 percent in their partner- and best friend-specific avoidance.

Just slightly less modest that analogous parental predictors, according to their claims.

Let me try.

In US schools during K-12, we generally learn functions in two ways:

1. 2-d line chart with an x-axis and y-axis, like temperature over time, history of stock price, etc. Classic independent variable is on the horizontal axis, dependent variable is on the vertical axis. And even people who forgotten almost all math can instantly understand the graphics displayed when they're watching CNBC or a TV weather report.

2. We also think of functions like little machines that do things for us. E.g., y = f(x) means that f() is like a black box. We give the black box input 'x'; then the black box f() returns output 'y'. (Obviously very relevant to the life of programmers.)

But one of 3blue-1brown's excellent videos finally showed me at least a few more ways of thinking of functions. This is where a function acts as a map from what "thing" to another thing (technically from Domain X to Co-Domain Y).

So if we think of NVIDIA stock price over time (Interpretation 1) as a graph, it's not just a picture that goes up and to the right. It's mapping each point in time on the x-axis to a price on the y-axis, sure! Let's use the example, x=November 21, 2025 maps to y=$178/share. Of course, interpretation 2 might say that the black box of the function takes in "November 21, 2025" as input and returns "$178" as output.

But what what I call Interpretation 3 does is that it maps from the domain of Time to the output Co-domain of NVDA Stock Price.

3. This is a 1D to 1D mapping. aka, both x and y are scalar values. In the language that jamespropp used, we send the value "November 21, 2025" to the value "$178".

But we need not restrict ourselves to a 1-dimensional input domain (time) and a 1-dimensional output domain (price).

We could map from a 2-d Domain X to another 2-d Co-Domain Y. For example X could be 2-d geographical coordinates. And Y could be 2-d wind vector.

So we would feed input of say location (5,4) as input. and our 2Dto2D function would output wind vector (North by 2mph, East by 7mph).

So we are "sending" input (5,4) in the first 2d plane to output (+2,+7) in the second 2d plane.

I have a counter view. I think a parent needs to educate their kids as well. So, while kids may learn about controversial gender topics one needs to be able to have an intelligent discussion on why as a family don’t subscribe to those. Encourage children to have a mind of their own and argue intelligently and hold their ground. It doesn’t come from shying away from public forums.

As to the last point - one of the biggest benefits of exposure to “bad” kids is knowing whom to stay away from and making independent decisions on that. Parents are not going to be around to guide children forever. They need to learn to make their own choices.

Unless you live in a school district that’s really not that great I would never recommend homeschooling. Cloistering into echo chambers is not healthy.

It's usually evolution or sex or race or something like that.

One of my friends was home schooled. It was at least partly about religious values, but I think it was also partly about him being a bit of a strange kid and getting along better at home. He went back to public schools in middle school, and that was real rough but I think he was happy by the time he got to high school.

I'm sure there are many reasons to home school, but the one I hear about most is religious.

In no way am I excusing the horrible treatment black people and indigenous people have received in the USA. It’s awful and definitely crimes that should have been prosecuted and the failure to do so is a stain on America and the ideals people want it to hold. But noting that it’s qualitatively and quantitatively different from a government organized industrial extermination machine doesn’t seem like something crazy. And pretending like power dynamics aren’t in play in terms of prosecuting Nazis is naive - it’s literally what Nazis said at the Nuremberg trials - it’s a sham trial because it’s just the victors killing the defeated. But it did manage to establish some kind of minimum legal framework even if it’s not as far as we’d have liked. Also important to remember that the US committed abhorrent legitimate war crimes in Vietnam even by Nuremberg standards - but the US is a super power and it’s an unsolved problem about who will hold a superpower (or even a nuclear power) to count for crimes against humanity.

I suspect it's the former, but it doesn't seem outrageous (like all "common sense"). I think the hard part is to replicate the parts one's parents did right. Like IT, when someone gets things right, they're invisible. When they get things wrong, it seems like the only thing they ever did. This is part of why I want my children's grandparents involved as much as possible in their life. I need to \alpha \times \grandparents + (1 - \alpha) \times \parents my kids.

I rode in one of these in Phoenix in June, loved the experience! Had to go to a pharmacy so purposely picked one a half hour across the city so I could just watch the car perform. Felt like the future (though it did glitch once). Made a sudden turn off the road into a parking lot, did a lap of the outside of the parking lot, and exited back onto the same road to continue on. Must have thought something was blocking the road and made a detour around it? Other than that it seemed pretty flawless.

It’s pretty tough to exercise or clean your house when getting out of bed feels like an insurmountable task.

Depression isn’t like an infection or cancer—it’s a diagnosis based on established criteria, as are most mental disorders. Experts may disagree on diagnosis or treatment, but that doesn’t make it useless.

By that logic, you might as well say autism is caused by avoiding eye contact—since there’s no blood test for it either.

The value was obvious almost immediately, but it was obscured by flashy get rich quick attempts. Google chose not to make money at first but that was a business decision, not a necessity: people were paying tons of money for ads and referrals years before they were founded.

That’s part of the difference with AI now: the internet immediately generated significant value almost instantly for relatively modest investments, so there were a ton of small and mid-sized companies who saw almost immediate profits from moving catalog sales or support online, switching software distribution from mailing diskettes to downloads, etc. and some people were able to cut into established markets where the existing companies were slow to change.

AI is different in two key ways: the first is the extremely high cost, which prevents a lot of the bottom-up growth we saw on the web, but the second is that it’s not a reliable technology like the web was so you can’t safely use it in the most valuable contexts. In the 90s, some people screwed up form validation badly but most people didn’t. Right now, companies would love to replace things like customer service or sales with chatbots but nobody on the market can make a system which is both safe and useful because things like prompt injection require theoretical breakdowns, not just attention to detail.

I use Sequel far more than Rails, but their relative importance is entirely different, and I suspect Ruby would be still be a minority language if Rails had not happened. Even if we take into account the numerous other contributions anyone could make, could they make up for or match Rails' impact? Doubtful. Hence, I find your claims a stretch.

If Evans were to purge the politics from contributions to the community, then he would be a fine benevolent dictator, and would manage something Matz has failed with (amongst English speaking contributors, at least). That would probably require purging some of the people (as far as possible), as happened recently. Could he do that?

Right but what does that have to do with the DMV. Waymo should apply for certain weather conditions and then the DMV says yes or no, then they stay the hell out of the way. Let waymo operate whereever they want and expand however they see fit and whenever they feel ready.

Like the DMV is actually checking Waymos map of a new area is good to go or not. Its just administrative burden.

> Sounds too similar to stuff like "Trad wife"

In a way it does. Traditional coding then?

> with an implied connotation of right-wing politics

For many people that is not al all a bad thing as it also implies a distancing from all those weird left-wing fetishes which many people would rather see gone A.S.A.P.

While you seem to consider 'right-wing' to be something bad it really is not. Neither is 'left-wing' necessarily bad, it is just that so many bat-shit crazy things have been pushed by 'the left' for so many years that it often is hard to take those who claim support for such seriously. Most of the bad things which have been (sometimes wrongly [1]) associated with 'right-wing' politics are understood to be bad by nearly everyone while the looney 'left-wing' ideas tend to be left alone for fear of being labelled as an '-ist' or '-phobe'.

[1] wrongly as in not being limited to 'right-wing' politics. There's plenty of racism to be had in 'left-wing' circles for starters.

The recent version of FSD in my Tesla is pretty amazing. Press "Start FSD" when in my driveway, and 20 minutes later it arrives at my destination and parks, without any input from me the entire time. I was skeptical too about FSD for a while but I'm starting to believe. These days I pretty much only disengage it when I'm impatient that it's being too polite. Unsupervised isn't far off!

AirDrop is based on AWDL, which is a proprietary protocol that requires low-level access to the Wi-Fi radio to implement. Apple told the EU that they have long-term plans to migrate from AWDL to the standard Wi-Fi Aware, but have not yet done so (and the EU did not require them to, only that they bring their Wi-Fi Aware support for third-party apps to feature parity).

I'm enjoying the concept. Tight browser integration/control. Controlling agents by commenting on Artifacts (Task List, Implementation Plan).

But the user experience for basic things has just been difficult. Unresponsive Agent Manager window. Agents hitting file permission errors because I don't have a proper "workspace". Agents getting blocked waiting for me to confirm a command line's "y/n".

> … showing me a new kind of market failure - where resources can be massively misallocated just because some small class of individuals THINK or HOPE it will result in massive returns.

Technically speaking, this is not a market failure. [1] Why? Per the comment above, it is the individuals that are acting irrationally, right? The market is acting correctly according to its design and inputs. The market’s price adjustment is rational in response. The response is not necessarily fair to all people, but traditional styles of neoclassical economic analysis deaccentuate common notions of fairness or equality; the main goal is economic efficiency.

I prefer to ask the question: to what degree is some particular market design serving the best interest of its stakeholders and society? In democracies, we have some degree of choice over what we want!

I say all of this as a person who views markets as mechanisms not moral foundations. This distinction is made clear when studying political economic (economics for policy analysis) though I think it sometimes gets overlooked in other settings.

If one wants to explore coordination mechanisms that can handle highly irrational demand spikes, you have to think hard. To some degree, one would have to give up a key aspect of most market systems — the notion of one price set by the idea of “willingness to pay”.

[1] Market failure is a technical term within economics meaning the mechanism itself malfunctions relative to its own efficiency criteria.

> Depression is caused by laziness and anxiety by hopelessness. My kids know that they aren't permitted to be lazy or say they are bored. They don't have anxiety because they have hope despite circumstances.

This sounds horrible. If I weren't depressed or anxious, being told that I wasn't ever permitted to be lazy or say that I was bored would make me so; and, if I were, then being told that I was lazy and hopeless would make it worse.

I never thought of my Olds Silhouette minivan as a high performance car. Neat.

The rubbery panels were great. I was at school pickup and another parent backed into it. They crushed the front fender to the firewall. Then they pulled up and it popped out.

They were freaked out but it was fine. And it's just a car.

Something else worth considering in comparison to consoles is that the games you buy on the Steam machine can be played on other devices and they'll be available long after the games you bought on console this generation EOL.

I've wasted $1000+ on console games over the years that I don't have access to anymore, yet I can still install the first Steam game I bought decades ago.

Here's what I think would happen if anyone, by tomorrow, could download GPT 5.1 for free and run it performantly on something like a $500 laptop:

* It would stop datacenter- and other related infrastructure construction, making huge investments effectively worthless for companies like Oracle and Amazon, and of course hurt the construction sector.

* It would hurt the companies you mention, plus a many more including NVidia, likely in ways that would lead to large-scale layoffs.

* It would seriously hurt corporate and VC investors and likely make them much less interested in large investments for quite some time, thus affecting other sectors as well.

* It would seriously hurt index funds and pension funds.

A number of years down the line, if LLMs are indeed capable of significantly boosting productivity, I'm sure we'd see a recovery, but when large bubbles suddenly burst there's usually some pretty serious fallout.

Everytime I see these kinds of arguments, it sounds like someone desperately trying to argue that a park playground is almost as entertaining for kids as an amusement park. Your example of 5 kids socializing with each other is definitely better than 1 kid at home. It’s also definitely worse than learning to socialize in a school of 500 kids each day. This is undeniable unless you have an argument of how a pool of 500 kids would somehow have less diversity of personality, thought, languages, physical features, intelligence, etc.

Amusingly the same thing happened to us, though we ended up on Slack/Signal/iMessage group chats. And I was the only left who stayed on Twitter and consequently the only one[0] with the confrontational style. To my good fortune, it was Twitter that I left, rather than the group chats.

And yeah, Elon is certainly a victim of this virus. I think Bill Ackman getting snookered into paying a tip twice in a classic cabbie scam was the first time I could clearly see how people could end up suddenly stupid through this disease

The author has exclusive claim to their own aesthetic sensibilities, of course, but the language in the piece suggests some degree of universality. Whereas in fact, effectively no one who is knowledgeable about math would share the view that noncommutative operations are ugly by virtue of being noncommutative. It’s a completely foreign idea, like a poet saying that the only beautiful poems are the palindromic ones.

Not sure if this is what you had in mind: Projected 2D views into a 3D "movie screen" environment is a feature of the Frame, per my understanding of their marketing, and of early reviewers' experiences.

If you meant, "do they take 2D render frames from videogames and convert them into pseudo-3d or actual 3d where the user can tilt their head to see a different view INTO the 2D game's universe, e.g. see behind bushes just by tilting head", then "no".

People drive because they need to get home for shelter, or get to work, etc. People live in cities because that's where the higher paying jobs are, again for survival, also given that one can use air purifiers at home and wear a mask outdoors. It is irresponsible to accept risk without reward.

It sounds to me like you're saying suicidality in children either doesn't exist, or shouldn't be treated, or should only be treated with talk therapy. If what you're saying instead is "this SSRI is especially dangerous" then ok, you and I just disagree about what information sources are reliable, and that's probably not a difference we can resolve. But if you're saying suicidality in children shouldn't be treated with medication, I'm curious whether you've ever met a six- or seven-year-old who wants to die. It is terrifying. It needs treatment. And talk therapy in children that age is honestly a joke. In the OP's place I would give my child an SSRI without any hesitation.

A nit, the word socialists is actually in the acronym (ie in the name). Fascism actually is a descendant of socialist ideology and Mussolini was a Socialist before inventing Fascism. Concepts of left and right only have meaning in one political unit at one point in time. The axis we use to judge right and left changes from time to time and is different in different places. Also, some fascist policies are similar to policies in socialist societies. And some policies are very different between the two. So the debate implied in your question, like most debates, comes down to the definitions of words.

This is why it isn't all that helpful to base political ideologies on history farther back than one human lifetime. The writers often meant something different than you think they did.
