While I agree with this I will point out that depending on your vision the service you get in getting the glasses rightly fitted is the hard part that may be worth paying for. FOr simple single vision lenses that's only weakly important. But for bifocals and even more critically progressives, the fitting is everything. I usually have to get two and sometimes 3 sets of glasses made before I'm happy. I've done tests where I have my vision measures four times in a row. They never agree. But some optics shops have a little leeway on progressives to tilt the degree of maginification in the center one way or the other. And that really helps when they get it right. It sucks when they don't.
So I don't mind paying for the service even though I know the glasses are not worth the price in materials.
I thought the reason they used ultrasonic was because it's more compatible with going through the screen. And the reason they used 3D ultrasonics is because it takes more information than the simple ultrasonic reflectance to decode the uniqueness. I don't think it was motivated by disriminating fakes. That was just a nice benefit for making phantom fingers harder to create in hindsight.
The thing that surprised me here is that in the field of 3D resonstruction, passive optical flow methods have come to dominate Lidar or moire patterns in probably all use cases aside from cars. And even in cars, for daylight operations it's arguably better than lidar for many practical issues.
But it's not the same as this example beautifully shows.
Optical flow is the technique of inverting a 3D object by the camera-or-object motion such that the parallax effect gives you the information you need to figure out the z-dimension. Lidar just times the distances, and Moire patterns figure out Z from spreading/bending angles of projected lines. Those require active illumination. Whereas optical flow just requires a video (or series of snapshots) from different angles on an object.
THe two reasons optical flow dominates is that first it's insanley cheap and compact (just a tiny camera) and second, because you get the texture/coloring/reflectance values at the same time, but perhaps most of all because it isn't a fixed field of view. Lidar and moire images are from a fixed field of view so you only get a 3D extrusion and you cant rotate the object on screen to see around the side. For that you would need the lidar point of view to move too and at that point you might as well have used optical flow. Of course for perfect metrology Lidar can be better, but seldom is that precision needed, even in a car. THe reason to use it in a car is just for diambiguation and night time driving. IN cars you don't get multiple points of view on distance object either so the optical flow only works on object close by where there's some parallax, but by then you might have driven under the flatbed trailer.
In this case the video image can allow the samsung to do 3D reconstructions. I don't know if they are bothering with that or just going with pure image reconstruction or not. It could be they don't even try to go the extra mile to verify the subject is 3D. I would hope they did since otherwise a photo might suffice to unlock. But here the video supplies the info it could use to a 3D optical flow reconstruction.
And surpise! its not actually measuring real 3D like lidar does.
The thing for me was realizing theses methods differ on that point. Sure I knew it all along, but I hadn't thought about it in this way before.
There's a reason apple went with costly 3D imaging. Yes of course there's the prospect of spoofing it with a 3D mask but that's a pretty invasive and premeditated attack. You can't do it on the fly like a video. As has been noted many times, given some preparation it's possible to spoof fingerprint scanners. indeed it seems it's probably easier to spoof fingerprint scanners in many implementations.

Stock shares are quantized because the company wants them quantized. They are free to change the multiplier with a stock split or join.
But if you have large priced shares you can influence who buys them and sometimes you wnat institutional buyers rather than whimsical day traders. Likewise if they are voting shares you prefer, usually, institutional voters over people who vote randomly.
Presumably the purpose of copyrights is the public good, not the enrichment of anyone. there are some ways I can think of that this works
1. Reward the copyright holders (via roylaties). The purpose of the reward is to encourage the copyright holder to share with the public their materials and perhaps encourage these creative people to make more things the public needs/wants.
2. It enables the creation of a market place. Market places are efficient methods of distribution. Without them the impact on the public of a new good isn't felt. SO we need market places and the abilility to sell rights for royalties fosters the creation of this.
There's some tension between these in that exorbitant royalties would crush the market place lower the multiplier on distribution and decreasing the impact on the public.
In a completely free market an artists profit motive might tend to optimize this because they would want to maximize royalty*copies sold. SO they maximimize both their incentive to share and the distribution in a balanced way.
One problem comes up if the royalty is fixed externally. Then there's no mechanism to price-adjust for that maximization. It's kind of like a command economy rather than a capitlaist one. And that was always the central flaw of the pure communist model-- setting those prices without the information gathered by the market on demand results in sub optimal production.
One the other hand you also can kill a market if the distributors have to negotiate individuall with every single person. Thus setting a fixed royalty may make some markets possible.
SO the only real argument google and others have is that somehow the command economy has selected the wrong royalty rate. I wonder if they would make that argument if the rate were set too low?? that too would harm the public as well. So we can't really trust them to make this argument. Better to trust the artists who have an incentive to maximize public impact.
I stopped using skype since webRTC became built into browsers. no apps to install, works reliably. Works on more devices than skype.

yes 220 will easily kill you. 110 can kill you but with high probability you will survive because you are below the let-go-point for normal human skin resistance and shoes. the 220 you have in your house is normally 3 phase 110 which means only 110v drop between any pair of connections making it slightly safer.
I think it refers to the rate of power delivery compared to the rate of power draw a vehicle woul duse to go 1000Mph.
example, suppose that sustaining 100Miles per hour in air drag were to require , to pick an approximate number, 25KW of engine power. Noiw scale this by 10. that's 250KW and 1000Mph. I'd actually say that the real number is about half that for most cars. so really this is 550MPH charging that someone rounded up.
Now this is wonderful in the sense that it's actually the unit you care about. If you are using your car sustainably on a drive across the country then if you have to recharge it every 5 hours for 5 hours then you aren't going to get far. it it takes 5 hours to recharge 5 hours of drivine then the rate of charging is equivalent to your rate of travel when moving. e.g. 60MPH. so if you can do it ten times faster then it takes ten times less long. It's a convenient unit as perplexing as it sounds.
One the other hands it's fundamentally insane. Asking a member of the public to make connections that carry megawatts is Bonkers. And in fact it never will be anything but bonkers... ever. The only form of dense energy storage that we've come up with that is not so explosive is in fact gasoline. It's redicluously safe when you consider the crazy amount of energy you are transfering when your hand is on the gas pump handle. Electricity isn't that safe. I don't think it can ever be. Megawatts of power just burns holes in things at the slightest resistance. Even a 1 ohn resister would melt metal instantly and probably spray plasma.
there's a reason why our houses have 110 volts. It's the transition point between air gap jumping plasma arcs that are self sustaining st elmos' fire death and spakes that just damp out. Get up to 480 and you are wielding plasma torches. Likewise 20 amps is where things like small resistances in connections start to just matter but can usually be managed.
megawatts is just bonkers. no way will this ever be safe as this fleet ages.
So you might be wondering how does one make $115 Million just vanish. First I'll assume they already have ruled out the obvious that it's just spent on lavish lifestyles or sitting in the accounts of the executives.
So where did it go? I speculate it never existed. How? Well imagine this, someone invests $1000 in the exchange when bitcoin is $1/coin. The exchange runner, steals all of it, but continues to tell the client that they own 1000 bitcoins. The the price of bit coin goes up 1000 fold. That 1000 coins now shows as a deposit worth $1million. If they withdraw some of it, well in the usual Ponzi fashion that money comes from the new deposits not from held funds since they don't exist.
That is there is nothing backing that $1 miillion dollars aside from the $1000 that was stolen. the $1000 did not appreciate because it wasn't ever converted to bitcoin.
So my guess is that some of this does exist in the accounts of the corrupt execs, but most of it doesn't exist at all. it's just $115M on paper, not in any account anywhere. Not $115 million stolen, its tens of thousands or hundreds stolen. If they go looking for these smaller amounts they may find some of it in boats and homes.
The interesting thing is what happens next. Clawbacks. If anyone cashed out of the exchange and it indeed was a pnozi operations then the bankruptcy lawyers will try to claw back the money from the people who unwittingly received a profit because they had the good luck to cash out. Now bad luck.
Exactly, AI's are basically compressors. It's already been demonstrated one can extract things like social security numbers and stuff from trained AIs that don't actually output SS numbers. Like Ragu spaghetti sauce, it's in there, just not recognizably at a glance.
I've wondered as well why cpu makers don't try to trap these problems with process oversight rather than prevent them. For example, Rowhammer is the use of the memory in a way that exceeds memory specs. You could say the same was true if somehow it was causing overheating or excess current draw. It exceeds specs. We have temperature monitors and current monitors to catch and shut down those two. So why not a monitor that detects rowhammer's spec exceeding aspects? I can't say exactly what that would be but it seems like a rate counter on bank accesses would probably tell you if a bank is being accessed faster than it can be sustainably refreshed. Heck you could even just have a wimpy capacitor that gets read every time the bank is accessed that is guaranteed to deplete before the one storying actual data deplete. So you should be able to detect this right on the memory chips themselves I should think.
That way you don't have to slow things down trying to prevent this in microcode. It's ahardware problem and seemingly a cheap fix. Everyone would buy ram that was rowhammer proof.
Perhaps I've misunderstood what Rowhammer was. I thought it was a a corruption attack caused by repeated adjacent bank accesses flipping bits in another bank. Thus I thought it's intent was to corrupt the adjacent bank not read back the adjacent bank. I don't even see how the bit flipping could work in the reverse direction to leak out information.
Yet this article seems to say it amplifies a rowhammer attacks efficiency and also can be used to spy on other processes.
