If I'm reading https://examine.com/supplements/magnesium/ correctly:

Vitamin D is currently the only Essential Vitamin or Mineral which appears to have deficiency rates at a similar level to Magnesium, if not greater. The metabolism of Vitamin D inherently is linked to Magnesium. Magnesium levels in the brain can be negatively regulated by an excess of parathyroid hormone (PTH), where PTH causes release of calcium into the blood (being met with an increase of magnesium to retain homeostasis) possibly being a contributing factor to chronic depletion of magnesium concentration in neural tissue. As vitamin D reliably suppresses excess PTH, it may exert neural benefits secondary to preservation of Magnesium levels in the brain.

A Vitamin D deficiency could lead to magnesium depletion (Vitamin D deficency allows excess PTH, releases calcium, depletes magnesium). So in fact, the opposite is the case right? At sufficient Vitamin D levels you shouldn't have to supplement magnesium, assuming no dietary deficiency of it. Right?
Ask HN: Teaching your kids technology without helicoptering
A baby will soon come into my life, and this gets me thinking about how to introduce computers and technology to young kids.

I think a lot of tech-literate people make the mistake of becoming helicopter parents when it comes to technology. They become IT support for their children, and the kids develop a sort of 'learned helplessness', where they expect their dad (usually... sometimes mom) to solve the technical issues.

Thinking back to my own childhood (born '71), I seemed to learn the most when left alone, with no distractions. Figuring things out this way seemed to make it stick out n my head.

What mattered perhaps was the (accidental) order which things were presented to me. A Commodore 64, a manual, some games, literally copying code from computer magazines. No internet to distract. This got my interest, and prompted me to learn.

What order should I present tech to a young kid? I'm inspired by this article which someone teaches his kid about gaming by starting off with old school games: https://medium.com/message/playing-with-my-son-e5226ff0a7c3

Here is a rough outline I'm the thinking of:

* First computer, a pi or similar, with Linux and no GUI. No WiFi. A few CLI-based games. A Python manual, and some python games to type in. Keyboard, but no mouse.

* (After getting ok at touch typing, and getting a very basic understanding of python, then ...)

* UI updated to split-screen shell and browser. Still no Wifi. Book about HTML, CSS, and simple JS.

* (After gaining proficiency making web pages, then...)

* Wifi added (switches off at bedtime?)

* (More proficiency)

* Upgraded computer to Mac

* Etc

Reading this back it seems a little dry, and perhaps expecting a lot of a little kid. And what will they think when they go to their friends house and see their bells-and-whistles computer?

What does HN think?
It seems to me golang and Rust are often being compared with each other. Given that Swift starts to be used on server side, I would love to see some comparison between golang and Swift, or Rust and Swift.

I'm glad the author mentioned learning new languages.
I have been coding Go recently and even tho it's not my main language, it has helped me to think about simpler designs when I'm using other languages.

Other than that becoming proficient in C and systems programming (Thanks xv6 book) was a major game changer for me.

> You're disproving the idea that anything goes forever, but what 'perpetual' actually means here is that it's extracting energy from an infinite source rather than a finite source.

There are no infinite sources of energy, only very very large ones.

> When someone says "perpetual motion machine" they're talking about turning 100% power into 200% power.

No, that's over-unity, a different concept altogether.

Anyway, it's way past my bedtime here (3 am almost), so I have to bow out here, apologies for that, it was an interesting discussion, I'm not sure if I've achieved anything but that's fine with me. FWIW I was active for years on a message board where 'perpetual motion', 'over-unity' and 'zero point energy' came up with great regularity, if you enjoy that sort of thing you might find similar minded folks there, it is called 'fieldlines'.

Yet nearly every programmer can understand a recursive descent parser.

...and I also hypothesise that nearly every programmer will come up with some form of recursive descent parser if asked to parse a recursive language --- without ever having heard of the term "recursive descent" nor parser generators. It's the intuitive, "natural" solution to the problem.

Is that the lesson? I would've guessed the lesson is to not try to murder people over the Internet.

Makes sense why AT&T was asked for data. I'm interested in why Tracfone wasn't. But I guess if it's enough to have a phone number and suspicion that it belongs to an iPhone, that's enough to send a search warrant to Apple. Given the popularity of the iPhone, I wonder if law enforcement has the option of querying Apple to see if an Apple account is tied to a number and save them the work of sending a search warrant to the phone service provider.

edit: replaced "subpoenaed" with "asked for data"/"search warrant". Doesn't look like a warrant was mentioned in the AT&T case.

How do we calculate how big of a cunt you are?
You are correct the language really shines when there is concurrency (not necessarily just distributed systems), because validating system invariants with the model-checker is just magical. I've also found the language to hold great value for specifications as such; Dr. Lamport seems to believe that most technical problems just disappear when you precisely identify what it is you want to do, and writing a TLA+ spec is an efficient way of accomplishing that. So, I've found it useful to write specs for solutions to very technical problems simply to clarify my thinking and root out areas of sloppiness.
I have never heard cognitive scientists make a big fuss over the Turing Test. Who've you been reading/watching?

No one is really responding to your question:

> Is there any evidence Apple has any advantage over the already quite competent, well-funded players who have already demonstrated significant progress in this area?

Yes. They obviously have world-class expertise in miniaturization, which is the key challenge for augmented reality glasses.

They also just released last year their AirPods, which have a custom chip for delivering low latency wireless streams of audio. Video or light field is the next step, but AirPods are on the market which means Apple already has an MVP out. That's a huge advantage.

The other key missing piece for any kind of mobile AR or VR is inside-out tracking. That, again, requires custom low-power silicon which is very much a strength for Apple. Compared to Google, Oculus, HTC, or any of the startups, Apple has much more experience with custom silicon. They acquired Metaio and Flyby, which build their machine vision base.
I feel like binding the journal to GitHub means that it's less likely to exist over the long term (where long term means >100 years, which is as long as I would expect an academic article to be accessible for).
How much do you spend on rape?
Depends on the purpose. Research suggests that people are both less persuadable and poorer decision makers when hungry. But post-prandial coma isn't great for meetings that require thought and focus either. Engineers often prefer their afternoons uninterrupted by meetings.

I try to schedule thoughtful meetings and meetings with engineers for right after standup so people aren't yet starving for lunch and aren't breaking flow. Right after lunch is good for quick status updates or outgoing sales calls. Meetings with the sales team or CEO go wherever there's a free half hour slot on their calendars.

And my boss will talk your ear off on useless tangents, given the chance, so I try to schedule meetings with him for first thing in the morning if I need to make sure we don't run out of time; just before he has a meeting, if I'm having a busy day; or at the end of the day if I know he has to be somewhere and I don't.
The only part I take exception to is the hyperbolic kill portion of, "intent to kill, injure, harass..." of the complaint. Seizures are unpleasant, inconvenient, and you might get injured on the way to the ground but they are rarely fatal, and if the victim was known to be at risk of such, he would be in an ICU somewhere. Did the perpetrator intend to kill? That might be hard to prove.
Cutting back salt can be taken too far -- I've known older people who suffered electrolyte imbalance because they'd cut out salt at the advice of a doctor. The body needs salt (and saturated fat, for that matter) in some quantity. Bad for you and not bad for you are not the only alternatives here.

>But I guess it's easy to erroneously conflate Apple's device security with iCloud security.

You might be overthinking it. I get the feeling that many people think of "online" as some sort of magical place where they are shielded from the consequences of their own behavior.
It seems like it would be useful to do this at the OS level too, not just per application. I.e. detect and filter out combinations of pixels sent to the screen that could cause a seizure. That would make the whole device a lot safer. I wonder if (a) this is possible and (b) whether it would interfere too much with desirable animations.

Edit: There is (offline) software to check if a video could cause a seizure: https://trace.umd.edu/peat.

Yes, for the reasons I already illustrated in my example. To be clear I am not advocating EBADF to be something you should live with. I am describing it as unintentional and as a bug. It is a time bomb for harmful race conditions.
> Edison runs an ancient kernel, the yocto image source is full of hacks, which do not suggest big interest in prolonging the device's actuality.

This killed it for me. I have one through Hackster.io and the first two projects I attempted bogged down in "need to compile this common package from source and hack it up to try to get it working" land. Meanwhile on a Raspberry Pi the same packages are an apt-get away.

I've been asked many times why someone would choose an Edison and the best answer I have is "if you really, really need to use an Intel board" and even then there are better solutions from them.
The Edison is a great piece of hardware completely hamstrung by the idiotic yocto linux distribution and tool chain. Despite being "x86" it's near impossible to add custom drivers or rebuild the OS. What's the point of being "x86" if you can't make use of the ecosystem? The Rpi has much better support. Don't waste your time. Intel isn't serious about these products, can't be bothered to actually support them, and won't open them up for use outside of their walled garden.
Wow, did not realize Apple is so gung-ho about sharing iCloud data with LE. I love the Apple ecosystem but when I have to start fracturing out my services it's going to suck.

Since the plates attract each other electrostatically -- one is positively charged, the other negative -- it takes energy to pull them apart. The amount depends on various factors: the size of the plates, how close they are together, how much charge is on them.
> “Spammed this at [victim] let’s see if he dies,”

Seizures can kill and this is widely known, so widely that we got instruction in high school on how to deal with a seizure victim to make sure they don't die.

Surely someone sending a seizure inducing picture to someone they know is prone to seizures is well aware of the risk they are taking, they are definitely not doing it to give them a monitor induced suntan. See perps quote above, definitely a slam dunk for intent.

Griefers don't care about the damage they cause, the more the merrier.

Internal meetings: Early in the day to get them out of the way. Clears the mind and stops the nagging “Don’t forget the meeting!” thoughts. If they are regular, have them at the same time so people can settle into a routine.

External meetings: When it is convenient for the external party. Travel time is 3 hours? A meeting at 8 a.m. would suck because the party has to get ready at 4 a.m.
> As soon as those options are out you have an inert piece of matter, by definition not a perpetual motion machine.

I think you're mixing up different comment threads. This was entirely about inert pieces of matter with 'dead' motion.

> You are thinking of motion in a classical sens

No I'm not. Look, if two billiard balls are 10 meters apart and that distance is growing by one meter per second, there is objectively motion there. It's inert motion, it's relative motion, but it's real motion. You can use any reference frame you want.

The only thing iPhone needs to become the best AR device on the market is rock solid low-latency positional tracking, low latency camera, and custom silicon for overlaying simple 3d graphics over the camera feed while using low power.

They don't need a headset.

They don't need stereo.

They don't need lightfield projection.

They just need an iPhone that feels like a handheld portal into augmented reality. I see no reason why they couldn't do that this year.

Heck, if they add positional tracking to the AirPods, it'll even feel immersive.

There's a few I can think of! First, the TLA+ GitHub repo has a bunch of examples[0]. The best one to start with is the Die Hard puzzle[1], where the heroes must obtain four gallons of water given only three and five gallon jugs. In the spec[2] we set up the system and specify all possible actions; then we model-check the system to see whether it can spit out an execution trace of actions to reach a state where we have four gallons of water in a jug.

The Wikipedia article also has some good example specs[3].

For your own first specification, I personally cut my teeth on a river-crossing puzzle with a farmer, wolf, and sheep.

I was thinking about it like this: I could tamper with the brakes on your car, but there would only be a very very slight chance they would actually fail at a life-threatening moment... probably you'd realize they were faulty, and even if they did fail you'd probably be fine.

If you really don't know until runtime what heap a pointer is in, then write barriers will have some kind of cost, but it should be low (definitely not atomic).

However, if you don't know statically what kind of heap a pointer is in, you're going to have a poorly performing GC system no matter what.
I think "proof" shouldn't be taken too literally. At the end stronger type system make easier to craft correctly working programs and less lottery machines.

Sure, it's annecdata... but just come to London. All of the old housing from the 70s or before (most of Z1-Z2) is single pane. Also, go search in Zoopla for double-glazing... landlords mark it as an extra for a reason (unless it's a new development, in which case it will be double glazing).

Well, I've talked to people and been to quite a few places in the UK, Scotland, etc. I know many people living in London, the UK and Scotland. We all agree. I'm pretty sure it's the same all over the UK

And for the rental prices that you pay here, it's pretty shameful the state of the houses, windows included.

If you want to be anonymous on the internet and you are doing this for immediate and spontaneous reasons my advice to you would be to forget about whatever you were planning, likely you will not manage to maintain your anonymity.

Ditto. Back then my parent often locked the room with the computer so that I could 'focus' on my study instead. And this guide helped my learning about pascal, C and then x86 assembly (when my father got so frustrated he took out the HDD and I have to run MenuetOS instead).

I think the section about Zen and Analytic thinking helps shaped my way of thinking. Before that I just charged blindly into problems, only to get stuck somewhere. But after reading the guide, I often stop for a while, thinking 'why doesn't this work?' and try to figure out how, back gathering all the evidences and make a mental model of it in my brain. Interestingly it is quite useful for programming too.
Is there a formula for that? I'm curious now.
