> In an effort to protect young people from the harms of digital tech

Any skepticism of these experts is clearly rooted in hatred of children.

Less snarkily, I'd like to see more parenting credentials for those purporting to advise me on how to raise mine, as these Really Smart People don't seem to have society on an optimal course.
> Every street address is public.

Not quite, but I'll give it a pass.

> All houses order food.

Nope, not everyone orders food. Perhaps in your bubble.

> Nothing private is disclosed.

Incorrect, it is PII. It is a real name connected to a street address first of all (one could use an alias; I do). And, possibly (potentially) also containing metadata such as what is being ordered, at which time, and how much.

Moreover, it denotes activity. If you want to lay low, your street address might be officially public (mine is) yet not receive spam on it.

For some reason, it isn't possible to only give a business your address (and other PII) when they need it and force them to discard it completely afterwards. Why not? Because when leaks happen, they're not hold accountable. See the essay Data Is a Toxic Asset, So Why Not Throw It Out? by Bruce Schneier [1]

I had once run a campaign where we had published a number, and we had to collect all responses to an advertisement sent to that number, to be pushed to a web system.

Didn't buy one of those phone numbers from an SMS API. Had good success with Tasker Android app.

https://play.google.com/store/apps/details?id=net.dinglisch....

(This was in 2012-13. Not sure if Tasker can do these things today what it could do in 2012, due to increased security limitations in Android)

Had a rule configured in Tasker to call a HTTP end point with the sender details. received timestamp and the text message content, whenever a message was received on the android phone.

Didn't have to write any code and could get it done in the Tasker app UI, as it had all the variables/tokens available and I just had to form the endpoint link to be pinged with those variables in the request.

A similar thing might be possible with Tasker or similar apps to do the other way round (ie, having the phone send an SMS via mobile network in response to a ping from another device on the wifi network)
> In the UK it's 07:00 to 15:00

All the schools I know of here in the London area start around 0830 to 0900. Some operate a club for busy parents to drop off their kids early but classes don't start until the rest of the kids show up.
With locked devices acting as a scanner for good behavior (and make no mistake, this is not about CP), the governments are nearly where they want to be: A world that is officially free (for propaganda reasons) but allows for every citizen to be imprisoned at once.

Now the only thing left is to install some devices that monitor every spoken word in our apartments and check it against, well, CP ain't going to cut it, religious extremism, maybe? Good thing that no one would be that stupid to voluntarily install such equipment in their home...
You need mass to accelerate. Not just electricity.
Cargo mass adds to structural stresses, and subtracts from mass available for increased strength and resilience.
This guy has a project which deals with this:

Whether scanning happens on the iPhone or in iCloud does not counter the problem that the dragnet nature of this makes it easy to weaponise.

Getting CSAM pictures in the iCloud photo library of someone you don't like does not even require physical access sometimes: For example, WhatsApp has a "Save to camera roll" option that's enabled by default: just send a bunch of bad pictures via WhatsApp, those will get synced to iCloud after a little while, and now that person is in big trouble.
In space, they just call the "space future" the "future". ;)
Not with our current understand of physics. Even reaching the speed of light takes infinite amount of energy for things with mass. This is because the faster you go the more massive you become. Furthermore, even before reaching the speed of light you will become a black hole as more energy is added.

Things without mass, instead, can only travel at the speed of light (photons for instance).

Finally, there is a quirk in the math that would allow for the appearance of faster than light travel. If you compress the spacetime in front of you and expand it behind you you could can move faster than light without turning into a black hole or needing infinite energy (Google Alcubierre drive for more information). It is only an appearance than faster than light travel because you would still move at sub-luminal speed in your bubble of "normal" space time, but the compression/expansion effect would drag you through space-time at faster than light speed. This, however, require so called "exotic matter", ie matter with negative energy density (this is not anti-matter, but matter that has a repulsive gravitational field) and it is probably only a quirk of the math and nothing more.
Taking a photo of it is even the first step in getting one of these -- you save two steps and ten bucks!
I'll just go ahead and pocket that template. Thanks!
Jenkins is good enough, any tool that you or your team already "knows" is good enough.

First, try to move any scripts that you might have and any dependency on yours or your team members workstation to a dedicated CI/CD tool (like Jenkins).

Second, from the beginning, make sure to follow the "best practices" on how to handle credentials and secrets. Don't add in plain text any credentials or SSH keys.

Third. from that point on, you can start looking at more complex tooling and/or deployment strategies (canary deployments, blue-green deployments, etc) to make sure updates on your applications won't break production.

CI/CD pipelines don't have to be fancy in order to work properly.
What are the relevant channels? My kid is very interested in it but the 3B1B type stuff is a bit too far ahead. He wants to learn algebra next.

"Perhaps critical thinking is not a useful skill in medical practice?"

I was having a discussion about this recently, recalling the vast majority of my experiences with medical doctors who obviously just follow a cook book approach to how they practice medicine. Worse than that is how many doctors cannot correctly explain test results. Seems like although they completed a lot of schooling they did not take enough math.
The two books I usually recommend for HPMOR fans are Worm (https://parahumans.wordpress.com/) and The Mother Of Learning (https://www.royalroad.com/fiction/21220/mother-of-learning)
Both considered to be a part of "rational fiction" sub-genre the same as HPMoR.
Well, it is a clearly defined service / product, with a clearly defined (and not all that expensive) price, so not all that bad, now is it?

Feels the hostility here is a bit overblown.
Very curious what could be the new thing given that they have already published the Codex paper.
I'm the other way, as in the composition API has not clicked yet for me.

I read the doc and it makes sense but once in my project, I fail to see why I would use it, and yes I use vuex.

I probably need to make a Vue3 project from scratch without vuex to get it.
If you mean React Native, many of those devs are now adopting Flutter fashion, at least from the iOS and Android corners of the Internet I happen to move around.

Just turn the energy into mass, duh.
I think the key difference is that it quickly moves from what's considered problems for kids (Ally had 3 apples, Booby had 2, etc) to abstract tasks and fundamental theorems in algebra, geometry and other areas.

The way math was taught in USSR and is still largely taught in Russia is by going as quickly as possible to calculus. I definitely studied limits and derivatives in school (around grade 8 or 9 out of 11 as I recall) and we briefly touched integrals in the last grade. There are some areas they don't really include, although in my opinion they should have, like mathematical statistics, which could be even more useful, but still.

That is a common approach recreated in some other subjects. For instances, teaching Russian includes not just basic syntax and phonetics but also just basic linguistic exercises like dissecting complex words and learning classifications, which you don't really need to talk it but they provide a deeper understanding.
I find it's much easier to audit the source code, and build the binaries yourself from that code.

Also, it's a collaborative effort. If you build your binaries from the same sources that other people use, then you can split up the work, and you all benefit from anyone's discoveries.

Obviously, we don't have perfect verification of the code we run. People can overlook things. Compilers can be subverted. Operating systems can be pwned. Malicious hardware can undermine all of our efforts. But let's not let perfect be the enemy of good, and let's not fool ourselves into thinking that faith in a corporation is a substitute for transparency.
In Romania, from what i recall, it was usually the beatings. Didnt like math? The teacher would simply use the pointing stick to smash your hands. I was fortunate enough to have liked math but some weren’t. And so there were the beatings.

Those attending “olympiads” were brainwashed into thinking that somehow they were superior and at some point we had to look down upon those whom, god forbid, chose something else but maths. Some indeed went on to have high paying office jobs in western countries, many of whom are now turning back. Apparently being trained to win olympiads doesn't yield an entrepreneurial spirit nor does it lead to riches, and after a life wasted they now just want to live a bit.
Jet fuel doesn't inherently mix with air, on its own.

(It does mix with air in high-speed impacts, which results in flame but not *explosions.)

Jet fuel, kerosene (intermediate in weight, viscosity, and volatility between petrol and diesel fuels) is remarkably inert for something that burns. You can extinquish a match in it.
I suppose winds will be the major problem for very big airships, but I believe there are lots of ways to deal with it. Using the wind in sailing is a known art. There could be technics to counter that? Or cruise along the wind and take a slightly different route. Or in general, probably you will have to take the winds into account a lot more, when planning blimps routes. And the winds are also different at different altitude.

And above a certain height, >10000 m, it is usually much calmer, but I think ordinary blimps cannot go that high. Different outside pressure etc.
Possible to mitigate with adjusting the amount of hydrogen by compressing/releasing?
Best way to avoid problems is to let it bite on something. It latches on for few minutes and then you can try to kill it. Triggerfish especially has such an alien anatomy that it starts snapping fingers when already in the cooking pot.
The sequel also makes a good read. The human angle might be slightly overplayed, but it hits the Crichton style quite well with computer analysis, foreshadowing and the tech dread.

Of the later works, Dragon Teeth (posthumously published) is worth checking out - no high tech but more a scientific western story.
Yes, but photons carry momentum even if they are massless, and you can't convert more than 100% of that momentum to energy for propulsion. So, if you achieve perfect efficiency, you can avoid them from slowing you down and still have to rely on internal energy sources to accelerate you .
To the authors: for the new user, your project is 90% your README, do this last 1% of work if you really care about your project.
Yes, but I am worried if a school uses question which can be solved with a trick that the whole instruction in class starts to revolve around tricks (which naturally will happen since the one kid who sees it will answer first).

This trick discussion reminds me of the great anectode about von Neumann:https://news.ycombinator.com/item?id=5950755
> Solutions are defined by the problems they address, not the mechanics of how they address them, or even particularly how good or thorough they are.

Yeah but what I mean is that as it stands you literally cannot implement a package manager based on ES Modules alone. So it’s strange to me that someone would say that ES Modules are the package management solution for JavaScript. That’s not what it is currently for. Though the relevant standards may certainly be officially extended in the future, to allow for standardized package management based on ES Modules.
Don't know, you have to ask someone at JPL.

I guess as beautiful as C++ and C code controlling the termodynamics of properllers in an hostile weather organism while looking for the presence of life.
When I started high school in Canada, my math grades were pretty bad. Probably in the 60%s (a C letter grade). I remember staring at a quadratic equation, struggling to understand why those 3 terms drew a curve. I had no intuition for it.

The summer before 11th grade, my father decided he had enough. It was time to learn math, Soviet style. He sat me down for a few hours each morning with problems from 6th and 7th grade Russian math textbooks - which was strange to me of course because I was about to start 11th grade. One important rule was that a calculator was not allowed.

Everyday he had a list of questions ready for me that he had judiciously picked. Back in Ukraine he was a regional physics Olympiad winner, and a gold medal winner (in the Soviet Union, the top graduates from each high school were awarded a gold medal - goes to show how they valued academics I suppose). I can pull up some photos if anyone is interested.

The questions were very clever and pedagogical. You developed intuition by solving them. And you couldn't solve them if you didn't understand the underlying principles. And of course, there's the word problems. I could barely read Russian at the time, so I had to take my time, but they bridge the gap between theory and application. And without a calculator, you are forced to develop techniques for manipulating equations and numbers. You get really good at it.

I aced math and physics for the rest of high school (and later graduated with a degree in Engineering Physics).

The western education system really fails us. My dad sitting me down with those elementary Russian math textbooks and enforcing a no calculator rule was one of the best things he could have ever done for me. The Soviet mathematic curriculum was designed by some brilliant mathematicians who understood the importance of developing intuition. That importance seems to be lost here. People think that quantitative intuition doesn't matter as long as you can plug your equation into Wolfram Alpha. But when you approach math that way, you don't develop an analytical and quantitative lens.

Wow! This is amazing. I have the C64 Maxi (and would buy an Amiga Maxi in a blink). I'd love if it could emulate the 3000UX and have an ethernet port (or wi-fi).

The extremely cool thing about the Maxi models is that a lot of the experience of retrocomputing is interacting with the device itself. That may be less important with Amigas and ST's because their keyboards are closer to the standard layouts we use these days so that the mismatch is not as significant as it is with a C64 or 8-bit Atari.

I'd be delighted to be able to actually work from an AMIX (or Atari Unix, Acorn RISC/UX, or A/UX) workstation. I did that a lot from an AIX 3.1 IBM and it was quite workable on a fast network.
> When the real problem is significantly harder. Social, governmental, institutional and systemic racism.

While I don't question that systemic racism is real, I don't quite see the link here. Isn't the kind of violence video games get blamed for more commonly committed by non-minority people who have mental health issues and/or were "social outcasts" rather than racially motivated? I mainly remember the topic as coming up in connection with school shootings and the likes, not potentially racial hate crimes.

100% agree on the looking for simple (and comfortable to admit!) fixes though. It is so much easier to say "we made a mistake letting kids play these games" than it is to face the truth that some people are either completely left behind by society or descend into incomprehensible madness for no comprehensible reason.
Not sure how exactly the lack of these skills could benefit anyone.

I understand that the lack of a school diploma is a huge drag in life and that can primarily affect people from disadvantaged backgrounds, but shouldn't they focus on improving the way they teach kids instead?
So, when you reach the "edge" you were going for, you arrive at the point when everything has already moved past your horizon (including Earth), there isn't a single hydrogen atom around, so you're stuck in the darkness forever?
It should be noted that the bitcoin network does not need to consume more energy to scale up:

- Using more energy does not translate to more transactions committed to the ledger. Second and third layer solutions can handle the world's transactional need with minimal energy usage, still using the security provided by the bitcoin network.

- The security of the bitcoin network is not dependent on the amount of users, and mostly driven by financial incentives. However, the more energy it uses, the more secure it is against attacks. As it is, the bitcoin network does not need to use more energy, and here's [0] a succinct explanation as to why.

In space you practically never ever want to accelerate radially away or towards whatever you're orbiting. Counterintuitively, on average that doesn't get your closer to or farther from the primary, it only serves to change the eccentricity of your orbit (raising the apoapsis and lowering the periapsis or vice versa).

What you want to do is accelerate either parallel or antiparallel to your orbital velocity (ie. tangent to the orbit). With a solar sail you do this simply by orienting the sail at a roughly 45° angle relative to the sun, allowing you to either accelerate or decelerate depending on which way you reflect the photons (the resulting force will be normal to the sail so in practice solar sailing is more complicated than that, but you get the point).

What I was trying to say was that the author completely misses the point about crackdowns in Tibet and Xinjiang. This has nothing to do with external threats to the Han population. And everything to do with internal threats to the integrity of the empire instead. Runaway provinces must be kept in order. That's how it has been for centuries.
Some BankID providers offer a regular bespoke ios/android app that replaces the physical dongle, which can operate in two modes, either by displaying the one-time code or by using the internet to autofill the code.
There's more to compete with though: train and ship. Both have severely lower carbon footprint than airplane as well. Ship might seem terrible at first glance, but the amount of tonnes being transported is so huge that it outweighs the fuel.

I had the same experience going from a French elementary school to a German school.

What we were taught in second grade only popped up again in 6th grade in Germany.

Then I went on exchange to the US in 10th grade and I noticed they were lagging behind the German system by about 2 years.

So US vs France must be a 6 year lag.
The copy below the fold talks about THEVIC20, is that another product from the same vendor and just a copy/paste mistake?
Actually ... I just looked up the etymology in yesterday's discussion of whether or not petroleum is dinosaurs.

Fossil means "dug up". So both fossil remains (remnents of ancient plants and animals) and fossil fuels are called that because they are dug (or drilled) from the ground. As opposed to harvested fuels (wood, dung, etc.).

https://www.etymonline.com/word/fossil

The popular meaning of "fossil" has somewhat orbited around the usage such that we associate "fossil fuels" with "fossil remains" rather than "dug from the ground".

I don't know if that makes helium a "fossil" resource, though I could see the argument for that. We don't refer to other minerals (e.g., iron, much of which comes from banded iron formations, or limestone, from seashells), as "fossil" resources, despite both being dug from the earth and biological in origin.
That's a common criticism that mostly relies on emotions and not facts.

These standardized tests are changed little by little every year and are simply meant to a) ensure similar educational standards for smaller and remote cities b) enable kids to apply to any university in Russia.

Although some specific parents and teachers in particular school might want to focus on repetition of the same problems and tasks it doesn't mean everyone will and it certainly didn't affect me that much. In fact, having some definitive rules on how they assess an essay in Russian helped me get 100% for it the first time, since it was objective.
I have a small toy project (essentially CRUD for images + tags + descriptions) that has a React frontend, mostly old class-style components. Having rewritten this frontend using Vue 3, my impression is that Vue 3 with its Composition API is just a different flavor of React with function-style components and hooks.
> As the article points out, the capability to scan things on devices is already deployed on huge swathes of devices in the from of virus scanners and content search indexing.

that's a ridiculous counterpoint. 1) no iphone has AV 2) AV and content indexing don't secretly contact the feds.

adding a new "background service that sometimes contacts the US government" is a big privacy regression.

Furthermore India is 3.3 million square kilometers, airtags have a range of about 10m.
What is "Russian math" like? And how does it differ from math curriculums taught in other areas of the world?

Why would they? It's local, thus, not saleable information.
It looked good and fit well for quite a few years and for not a lot of $$. Lots of pockets too. Nothing else more interesting than that :)
"Zeppelin" is a manufacturer designation or brand name, akin to "Kleenex", though it's become somewhat genericised.

It helped me a lot.
> Have you ever wondered how it's possible that the same "stupid" Americans that don't learn integrals and group theory in highschool somehow manage just fine in university and later on in life?

They do just fine because they aren't selected to do jobs where they need those kinds of skills, because they tend not to have them.

If they were taught the stuff at least they would have the choice.

I'm not in favour of brutalizing the kids though, I think that ruins the experience for them. But a lot of kids are more capable than we think and ought to be shown advanced subjects.
