Newtonian physics looks kind of logical. It's completely wrong, but plenty of decisions are based on it. Despite that we know is wrong

It's not *completely* wrong.
In fact back then when it was discovered, it was experimentally proven to work within the parameters which were tested.

The reason it was used then and is still used now is that within this range of parameters, it still works. For everyday use, what newtonian predicts is within what is observed. That's a precise enough model.

What happened is that scientists started to consider much more extreme paramters range (higher energy, faster speed). At that point, newtonian physics breaks down. Does it mean that all the past results were wrong ? No it simply means that it's a model which is only works within a certain range of parameter (it's good for everyday use - you car) if you need to consider parameters outside this range (space ships, planets) you need a better model (general relativity, etc.)

Note:
- with Newtonian physics we speak about a physicis model. About a model that's used to approximate real-world events. This kind of things only get experimental proof (prediction fits the measured data or not). And will eventually get superseded by a better model which works better including for some corner cases or at higher range, smaller scales, etc. (String theory and such were born as a tentative at a better model than the dichotomy between relativity and quantum mechanics).

- with TFA: it's a bout a *mathematical proof* that 2 different models are really actually the same stuff just expressed in different ways. Take one model, tweak the equations, and you should obtain the other model. It doesn't speak about the quality of the models themselves, just the mathematical links between them.
(I fact, the quantum mechanics model has its limitation - what you call "wrong" and what I call "use it only within the range of value where it works the best.
QM works best at predict very small scale phenomena (particles, waves, etc.). QM completely sucks at being useful for anything at the other end of the scale: QM is a piece of shit for astronomy. And vice versa: relativity is good when you consider stars, useless when you consider particles. 2 models, each best at a different scale. And strings being a possible future model that could simultaneously work at both scales.). ...but usually, when you have a newer model, that is better experimentally, you usually also need to find a mathematical "link" between the two, an explanation why the old model used to work and only got contradicted in your experiment.
e.g.: take the relativity equations, and use them to compute the motion of your car - the level of energy and speed are so small, that all the "weird parts" of relativity can be approximated and rounded to 0, what remains ends up looking exactly like newtonian physics. Newtonions physicics are the same, simply with the relativity parts neglected, because they don't play any significant role at that scale.

Science constantly bases decisions on kinda logical principles until those principles are proven to be wrong.

Newtonian physics looks "kind of logic" because it's a model designed and tested and proven to predict a range of events (reasonable speed, low energy, human-size scale instead of particles, etc.) which happens to match what our monkey-brain have evolved to cope with.
(our ancestrors never had to think about nuclear bombs, supernovae, tunnel effect in electronics, etc.)
That's also why it got discovered first (we didn't first invent relativistic physics and the newtonian as handy simplified formula for some type of problems), because that's what was easiest for our monkey-brain to think about.

"wave-particle duality is simply the quantum uncertainty principle" gets a "no shit" straight away from me, though I guess a rigorous proof of it is kind of news.

That's how science work. You don't base your decision on the mere principle that it more or less looks kind of logical.
(After all, it only looks "kind of logical" to your *brain*, which has spent the last few million years being optimized to help bipedal monkey survive together in the savanah. Actual science can some time feel "weird" and defy logic, because it defies the monkey-brain logic. - e.g.: the sum of all positive integer is a negative fraction)

You do thoroughly prove that by the numbers.
Yes, the double-slit experiment (where single particle behave like waves) strongly suggest that the uncertainty principle is at work (there's not *a signle photon* going through the slits, it's instead a function showing the distribution of the probabilities to pick it up at a certain place).
Now, we have mathematical proof that's indeed the case.

Science: the only place where it's actually correct to spend the time and mental ressource to formally prove that water *is* wet, and fire *does* burn. Because, along the way, you develop mathematical tools which come handy to do more advanced science.

If I own a car located in Sweden, and I'm a US citizen in the US, arrested in the US... can the court compel me to make arrangements to produce for the court something in that car's glove box? I don't actually know...could one? Its not entirely unreasonable to speculate that they could make that demand and then hold me in contempt if I refused to make that arrangement.

Depends on what is the car's glove box.

- If it's something that Sweden doesn't give a damn about (some trivial object), well you could produce it for the court, and the court might be unhappy if you refuse to produce it and actively make obstruction (if the court offer to send a swedish cop to retrieve the object and you refuse to give the key your are kindly asked to provide them, you're the problem)

BUT

- If it's something that is illegal to export out of the country according to Swedish or EU law (weapon, endangered specie, nuclear fuel, etc.), then you CANNOT LEGALLY produce it to the court. What the court is asking you is illegal in Sweden. If you do it anyway, you're going to have big problems with a Swedish court.

According to you, it is also the legal property of Microsoft US. They don't need to compel the Irish to do anything. They can (arguably) simply compel the US entity in their jurisdiction to summon its own property.

Sorry, no. They can't. It's not legal in EU countries (and a few other europeans countries) to move private data around without consent.

Microsoft US cannot summon data in Ireland, without the explicit consent of the data owner. If they move the data anyway, they can be sued in Ireland for it.

While in a foreign country, you cannot commit a crime (under that country's law), even if it's your home country asking for you.
(Otherwise, spying would be entirely legal: because it was done on the order of the spy's home country).

It is also subject to the orders of its owner, what with it being property and all. So as long a Microsoft US doesn't demand that it do something illegal by Irish law, it has to do whatever Microsoft US tells it to do.

But moving private data around without the owner's consent *IS* illegal in most EU and other european countries.

What the US court asks *IS* illegal in Ireland.
and the US court HAS NO power in Ireland. They are giving orders out of their jurisdiction.

If so, this boils down to can a court compel a property owner to direct his property to do something (such as forward a document in that properties possession), even if the property happens to be in another country? (one could also substitute "property" for "slave" in that sentence... and

When looked at like that, its not really ridiculous at all.

Except forwarding that document is absolutely illegal in Ireland.

It works better if you substitute "slave" in that sentence: What if there is no slavery in that country ?! What if all humans are considered free?

This is not a case of a court making demands directly of an Irish citizen; which is the possible strawman you erected.

No, but the data happens to be in Ireland, not in the US. Irish and EU law apply there. Nobody gives a damn shit about US there. Exporting the data IS illegal.

Again let's change the details. Let's take some Extremist / totalitarian government. The goverment asks one of its citizen to assassinate a target (that etremist / totalitarian regime has law that make this request legally binding and mandatory). The citizen then travels to US, and shoots the target: an innocent US citizen - who happen to have angered the government with some publication.
Is the assissnation legal, even if it was ordered according to the law of the extremist government? No, because that government has no jurisdiction in the US. In the US, US-law apply, and you are not allowed to shoot random inocent people, just because some other random dude accross the globe gave you an order.

Same situation here. Data is Ireland. Irish and EU law does apply. Law says that it's illegal to export data without owner's consent. Microsoft can't give it to US, even if US courts orders to.

This is the case of a court making demands of a US corporation. The nature of that demand is that the US corporation in turn compel its own property in Ireland to do its bidding.

It might seem equivalent in the end, but they are NOT the same thing. For example there is no way the courts in the USA can compel ME to do anything because I am not in the USA, nor am I the legal property of any entity in the USA.

And juste like you're out of US' jurisdiction, so is the data in Ireland, according to local laws.

A person defies a valid court order? They're arrested and in jail for contempt of court.

Unless that "court order" comes from a completely different country, and ask the person to do something which is absolutely illegal in the current country of that person.
Then the person can laugh and throw the court order in the trash can. (But depending on the "completely different country" 's law, the person's car which was left back there could be seized and destroyed as a retribution).

That's exactly the situation here: A court in the *USA* issues an order to search data in *Ireland*.
No US court has any power to order whatever in the EU. They cannot force anyone in Ireland to do anything. They have no power here.
Not only that, but strict EU laws about data privacy make it *illegal* to do what the US court ask in any country of the EU (and a few other non-EU European countries). If anyone in Ireland were to do what the US asked, they would be thrown in jail for their illegal activities.

Now the court wants to harm Microsoft-US, in retaliation because Microsoft-EU choose to abide to EU-laws and not do what the US court told them to do.

You end up with a giant wall, with 4:3 aspect ratio (as each tile is square).

But, as he mentionned, driving 144 display tiles in total is going to be a little bit complicated.
(5 display max per Radeon card. 4 Radeon cards per motherboard. 20 displays per PC Tower. You could probably driver 2 tiles per display port using splitters like matrox is down, so you need 1 PC tower per 40 tiles. So at least 4 bit PC towers to drive all this).

Well from a purely theoretical point of view:
it could be possible to survive on a low-carb diet, eating only proteins and fats and avoiding sugar completely.
(The kind of diet that bodybuilders use).

In that situation the body obtains most of its energy by burning fat and maintains blood sugar levels by gluconeogenesis.
(This metabolic regime consumes some proteins, hence the increase need of meat to avoid starvation).

But it's complicated to get correctly.
Compensating the Type 1's lack of insulin is much simpler.

That's what some think early human diet looked like before agriculture (the theory basis behind the paleo diet).
That's also used by body builders to burn fat (as mentionned above).
Before insulin that was the only way to keep Type 1 diabetics alive.
It was also recently been mentionned as a insuline-free alternative treatment. Was mentionned on /. recently.

I think it's not so much that no one cares as that decent video calls require more infrastructure than a phone. The camera needs to be steady, lighting needs to be good, sound isolation needs to be good... all in all, video calls work much better from a laptop sitting on a desk in an office, or better yet in a conference room with dedicated video-conferencing equipment.

And some goes for most other forms of video.
Making a decent video clip instead of just quickly recording something with a camera phone, is difficult.
Much more than putting some effort into a photo.

Until some startup finds a way to do the video equivalent of Instagram (i.e.: making it easy to create nice video clips) video won't be a major communication medium.

Functionnally: They are equivalent.
- In both case, it's a payment system, and supports NFC protocol so that you can pay wirelessly just buy putting the phone next to the payment machine.

Hardware-wise: They are not exactly the same.
- Google Wallet is just a generic payment system (like PayPal, etc.) In most phone, it's simply the OS (Android) being able to talk over NFC to the payment machine. It's up to the OS and Application to hangle security any way they choose (might or might not involve hardware - most implementation do not. But some smartphone did have some form of it).
- Apple's system specifically uses a separate piece of hardware: a TPM-like chip that is secured and hardened and holds the actual banking information (which never leaves the chip). Security is by definition handled by the specific chip.The whole systems works like a wireless credit-card with a smartphone bolted next to it, the smartphone being able to act as a GUI to the credit card, but the card handling the transaction themselves.
Some Android Smartphone did in fact work exactly like that. (Had a dedicated chip which was more or less a micro credit card, which handled the NFC talk it self and the smartphone merely interfacing with the card).
- NXP is a vendor of chip that makes hardware components for payment. They've worked on Apple's chip. They are now selling this chip for android smartphone manufacturers too.

Apple's emphasis is on security: They want their "dedicated non-hackable credit-card-on-a-chip" approach.
Google's emphasis is on making the technology available everywhere. High end phone will have a chip, low-end phone will simply emulate a virtual credit card by having a piece of software talk over NFC. But it's going to be available as widely as possible.

From a security point of view:
Meh.
Google's idea isn't the most secure ever: it rellies on the OS being good at correctly isolating and sandboxing apps. But bugs happen.
Apple's idea isn't perfect either. In theory, a separate piece of hardware is easier to make tamper proof. In practice, it's just a subpart of the same piece of silicon as the rest of the system (they are SoC. System-on-chip. Nearly the whole modern smartphone is a single chip) hacker are bound to find a way to leak sensitive data (I mean, for fuck's sake: hackers have been able to deduce GPG private key by reading signals leaking out of a compute.

So what? Since there's no central authority to block transactions or seize funds they'll simply be passed around until any relation with the crime is meaningless with almost everybody in the transaction chain is blissfully unaware that somewhere they were stolen.

Will they pass them around? Enough to blur any relation ship? In a secure way that never leaks any identity?

Remember that they have adversaries like government who (as recently proven for the NSA, for example) have quite a few ressources.
A single policeman might not be able to pull enough data and analysis.
But if goverment suspects that some big danger as possible ("pedo-terrorist pirates!" threat, or more realistically: juicy corporate spying opportunities :-P ) and decides to throw ressources at it, tracking might be achievable.

It's not impossible for the thief to manage to get out un-identified. But it requires being particuliarly smart.

1 single transaction tracked ? Yes, you mostly get just 1 other bitcoin wallet.

Massively track thousands of such transaction? (that's beyond the capabilities of a small budget research team. But that's well within the capabilities of any decent government) And correlate them with "end-point transaction" (transaction that can be traced to a real-world identity: buying something from an e-shop using bitcoins and ordering it delivered to an address) ?
then, if the tracked person isn't using an insanely high number of "tumbler/mixers" (i.e.: laundering) or moving it in-and-out of tons of exchanges (basically also a form of mixing), you might find some correlation:
aka "a significant number of these BTC have transited to these wallets all mapped to the same real-world address/person"
that is not enough to warrant an arrest, but that is enough to put these real-world persons with the shortest "path" to the tracked transaction on a suspects list for further investigation by classical police work.

(Saddly, often government don't have such concepts of "suspect list". Very often such unsure statistical result won't be used as a "hunch" but will get you put on the "no fly list" and such)

Currently, the way it's implemented in european country, McD doesn't use it to reduce workforce (you're still required to walk up to a clerk to retrieve your order).
McD uses it to accelerate it service and increase the "number served": by the time you finish typing your order and have confirmed, the order is already broadcast to employee's screen. By the time you finish paying and walk to the queue, your order is already ready.
This cuts drastically the waiting time, and european McD's use to cram more customer served per minutes.

In the long run such stategies won't neceessarily reduce the workforce that much, but on the other hand, they will be used to propel "fast food" to a whole new definition of "fast".
On the other hand, that will probably be quite alienating for the workforce: no more breaks between customers, no more small talk while ordering. Work experience is going to be Charlie Chaplin's "modern times"-style: read the screen, pack the bag, hand over the bag, as fast as possible and repeat so the next customer doesn't need to wait.
