UWB is essential for secure vehicle unlocking. Bluetooth isn't, because it can be relayed. It'll give Apple a nice integration point with your new car.

For scooter rental, it'll be way smoother than opening an app and scanning a QR code. You can just step on the scooter and go.

(My wife hates the QR-code scooter app experience so much that I generally unlock both scooters under my own ID when we're going around together. Fun fact: there are geocoded low-speed zones in Paris, where it limits the scooter to 10 kph in some crowded pedestrian areas. Fine. But when you unlock two scooters with the same phone, it uses the GPS location of the phone to decide when to limit or un-limit the speed. And a lost Bluetooth connection can leave it stuck at low speed. But I digress.)

UWB will also improve the ergonomics of contactless payment. With the current system, you have to hold your phone really close to the reader for a few seconds. UWB could allow an instant gesture.

Agreed. I do know some projects that do a lot of code generation that end up with huge files, though this is probably largely caused by C++’s templates forcing too much into headers (which newer versions fix).

It’d also be nice if parallel make had better load balancing.
The average college football player, with their 2% chance of making it to the NFL, is worth the median NFL salary of roughly $800k? This has gone a little too far off track for me.

The core issue here is claiming that profits are derived from not paying players. There are plenty of teams not paying players and losing money. The top teams could pay players well and still make profit. There's a small Goldilocks zone where what players should be paid lines up with the team's level of profit. The old "profits come from not paying workers" canard is a story with little to no explanatory power here.
This isn't pedantic, it's irrelevant. It is a generalized density function. Whether or not it represents probability is up to the way you're using the function.
I've pursued this before and I came to the conclusion that the only reasonable way to do it is to hire a virtual assistant to help you look for projects. It's just become too much of a numbers game. I personally hire people from Latin America and recommend it if you're in North America for time zone compatibility. If you're in Europe probably somewhere in Asia is better for time zone reasons.

I guess it depends on if UWB devices can detect the location of beacon devices regardless of whether or not they specifically integrate with the "finder device"'s manufacturer. IE would Toyota and others have to add some code to work with Apple's chip, or can every device find other devices in beacon mode? (Another hurdle is if Apple limits what you can do with the chip as a developer, since they've done this for their NFC tech)
It feels like this is the key to unlocking useful AR [1] for low powered, lightweight headsets. If the heavy lifting for locating and interacting with objects in 4D space is done with UWB, you don't need to do too much computational heavy-lifting - reducing bulk, increasing available space for batteries and reducing battery draw.

[1] Right now I can't really see a killer app for AR, something that would make you super-human enough to want a layer of abstraction between you and the real world. However if I could remotely interact with objects through walls, like turning off a lamp in a bedroom or seeing where my wife is and opening up a audio chat with her so that we're not yelling to hear each other, all of a sudden the trade off of having to charge and wear another device seems less annoying. All of a sudden you have powers not unlike a sorcerer.

Bingo. Games that let you trade actually are in legally shakier territory because of the cash-out potential.

I think this thread is missing the main reason why gambling dangerous: it can turn money into more money. The blinking lights and the Skinner box pyschology only play a supporting role to the main attraction: which is the belief that you can walk out richer than you walked in. This particularly plagues the poor, either because they are desperate or lack the financial accumen, and is the main reason why it is regulated. In the UK where sports gambling is legal, it is widely considered a blight on the lower class.

The fact the next roll could win back everything I've lost tonight AND make a profit on top, is far more dangerous than the next pull being merely able to finally get me that coveted Overwatch skin.

Hence why colloquially everyone calls loot boxes gambling, but no one has been able to make a strong legal case for why Overwatch loot boxes constitute gambling. If anything, Counterstrike is in the worse legal position and has had ACTUAL gambling scandals due to the high resale value of certain weapon skins.

This is a good way to pick a few 64 bit numbers without duplicates, if 64 bit numbers is what you need.

I didn't see any replies to you mention this part, but Vitter's algorithm works on an unknown number of samples. You can pick a 64-bit number uniformly when you know in advance you have exactly 2^64 choices. But how would you pick samples from a stream with equal probability, without knowing how many items are in the stream? Maybe it's 3, maybe it's 2.493e85, you won't know until you run out, and when you do, you want to have picked some items from the stream with uniform probability.

Drones have 10 to 30 minute loiter time, and they don't reach 10k feet. You're overestimating the ability of small craft to detect, track, and even reach the operational area of large passenger jets. These things are moving at hundred or more meters per second vs a drones ... 15? By the time a vision system had enough pixels on target to detect, it would have seconds to move into position in front of it. And how exactly is it supposed to know the jets velocity and heading?

Let alone it must hit the inside of the engine to do more than become a scratch on the paint.

Still, takeoff and landing maybe ... But still this kind of visual detection, tracking, and maneuvering is harder than you think.

I think Richard Evans is showing his age as far as cultural disconnect from the youth is concerned (which has extreme importance in his analysis, as the Nazi Party was comprised of mostly of disaffected young adults).

"The level of political violence in the last years of the Weimar Republic was astonishing: in the first half of 1932, 84 Nazis were killed in street clashes with other armed groups, as were 75 communists. In the Prussian election campaign that summer, there were 105 violent deaths, and police counted 461 political riots with 82 deaths. This has no parallel in today’s democracies, for which we should be thankful."

The Internet is the new beer hall. We're only seeing the tip of the iceberg of the transition from digital spaces flame wars to meatspace brawls.

In short, Trump isn't Hitler and Bojo isn't Mosley. But they are certainly canaries in the coal mine for what these societies are trending towards. Or to put it another way, it took the Nazi Party six years to grow the war machine that took over Europe. But before it took power, earnest adherents of the Weimar Republic spent 13 years inadvertently sabotaging their own systemic predicates to try and stop Hitler and/or the KPD from spreading and seizing power.
> UWB is essential for secure vehicle unlocking. Bluetooth isn't, because it can be relayed. It'll give Apple a nice integration point with your new car.

The radio technology involved should have almost nothing to do with the ability to perform a relay attack. There are two straightforward mitigations:

1. Timing. The two parties confirm that a message can round trip in a specified, very short time T. This proves that the distance between the parties is T/2c or less.

To be useful, T should be, say, 20ns or less, which requires a bit of clever crypto to make the actual exchange fast enough.

2. The transmitter attempts to localize itself, using GPS or other technologies, and refuses to authenticate unless it’s near the receiver.

There is reason to believe that UWB will help with localization. I see no reason it would be any better than any other technology for time-of-flight measurements unless sub-nanosecond resolution is needed.
Maybe someone cares to speculate about replacing Bluetooth for AirPods.

It fits easily in the bandwidth of UWB. AirPods are ideal candidates for better locating ability. I can’t say for certain but a rough googling suggests that the radio accounts for the bulk of the energy used in an AirPod, and UWB appears to have better efficiency per bit.
Good points. Your answer would pass the systems design interview and mine would not.
Anarchy Online was one the best games I played. It was so challenging and cryptic , learning all the skills to use parts of the environment (computer literacy to use the 'grid').

Maybe truer black on OLED screens, if OLEDs can be printed on a back plate like that.
Tesla's speaker system is 200/560W. So it's possible to get to 50W just from screen and speaker savings. And that's assuming constant worse case use of the wipers: high speed and full load like you're driving through a waterfall. Pulling up a spec sheet for a wiper motor, it looks like normal load is only supposed to draw ~6-10W.
Also ov/ev isn't something a person can get. I mean it might already help for some personal sites if they can be tied to other pseudonyms the user has online so for example sites of more or less well known open source software could get a link to the github or whatever into the cert to directly bind the dev of that software to his website, without having to know who is behind that.

The identity problem is always fun. I mean i don't care who someone is in real life, i only wanna know whether i have the site by the same individual who made something else.

That can be easily and automatically verified (see keybase) and might be more than enough for a lot of things where there are only normal people involved.

It might also be helpful of a given company is more commonly known behind another online entity. Like for example if pewdiepie had a company which he uses for what he does, the link to his yt would be a much greater indicator of validity than some random company name or even his own real name (which not everyone may know).

For pure DVs i think they should be able to issue them themselves. I mean the only thing those prove is domain control and with dnssec+tlsa there's a great way that domain owners can prove that they are in control of the domain and aurhorize a cert, also this lowers the number of trust paths significantly as there is only one possibly trust path over the TLD, and not like 150 CAs from who knows where. Also both the domain owners and the users have less entities they have to trust, as the TLD managers have to be trusted anyway as they ultimately have the full control of their domains,and thereby could make a DV cert themselves over the CAs anyway.
I’ve made guesses at specific product applications based on forthcoming tech from Apple before and the focus is too narrow. It may _also_ be good for secure vehicle unlocking but it wouldn’t make it in unless it has a dozen more useful and ecosystem expanding product applications.

Yes, time of flight is what UWB measures. But Bluetooth isn't suitable for measuring TOF to a useful accuracy. (I'm not sure what the Watch unlock feature is using.)
> 50W for 5 hours is 250Wh, which is a mile extra range. That’s worth having.

That represents about 0.5% of a Tesla's advertised range.

Reason for Germany success were the industries built for war with money and resources taken off others. Combined with reasonable work ethic and being on the right side of USA - Russia debate. (Which included things like Marshall Plan.)

For a time, Italy was successful too, but they slipped. Why they slipped I'm not fully clear on.

Israel got USA support and investment, including military. That's about it.
(You can repeat the same for e.g. South Korea, who are an even bigger success. For now.)

UK was a success (for a time) based off a huge empire and consequent innovation needed for war and to adapt for living in weird places, and to look like they own the world and not like a dark smudge of coal.

Why would one levy a tax on flights if one's goal is make travel more efficient? Why not simply tax transportation fuel based on energy or carbon content? The latter would incentivize industry to develop more efficient modes of transportation.
To be honest, although i think it's sad that Britain left.

They were never fully in on the EU as France and Germany are ( i'm Belgian).

So i'm not sure if a agree as much with your opinion as you want :)

> Right now I can't really see a killer app for AR, something that would make you super-human enough to want a layer of abstraction between you and the real world.

For me the key uses of AR technology would mostly have to do with abstracting input and output (mostly) away from the actual physical devices involved, which would benefit from UWB for certain cases but really wouldn't hinge on it.

For a simple example: Sitting in an airline seat, and having a virtual 'big screen' to watch a movie - but having it anchored to a certain relative position, so I can still look left and talk to a cabin stewart without removing AR glasses (and still have the film playing in my peripheral).

Another simple example would be providing a GPS 'HUD' when driving, similar in result to physical devices you can currently get that project onto windshields. UWB stuff might benefit here by providing a reference point to anchor virtual objects to (e.g. saving a position and orientation relative to the physical chip in the car).
