If you fall asleep while driving, I'm not sorry to say that you're a fucking ignorant driver, a danger to everyone around you, and happy to commit murder in order to... what? Get home quicker?
Pull the fuck up at the first sign of sleepiness (and don't be tanked up enough that you just collapse). Sleep for half an hour. Try again.
Even the most exhausted person will recover enough in a half-hour or so, or just not wake up until they're ready to drive again.
Fuck saying this is a plus of autopilot. Any number of cars have driver alertness warnings. They don't need to pilot the fucking car in such instances, they need to switch off, brake heavily and refuse to let the driver continue until the police arrive.
"Do Cellphones generally have the ability to assign a ringtone to a group of people?"
Er... like fuck yes? All of them? I had a "family" ringtone on a black-and-white LCD Nokia, for fuck's sake.
POTS doesn't allow lookups without the telephony company's co-operation anyway. Last time I tried they had to intercept the lines for hours "until the guy called back". And that's British Telecom, who have an almost-monopoly on the UK telephone system for the last 100 years. You never find out what happens, for various legal reasons, either.
That's nothing to do with SIP whatsoever. If anything, SIP is equal to or better, in that regard.
That your ISP is shit at putting on QoS? What's that got to do with anything? Were you tagging the traffic at your end? I've never ever had to do more than tag traffic properly for phone calls to work (and, yes, I have put in switchboards with dozens of lines, extended them to hundreds of lines, hit capacities and need for strict QoS, applied it, and then carried on for years with those same settings perfectly well).
Robocalls? Well, if you have SIP, turn on the "don't accept calls from unknown numbers" crap, or at least push them through a menu, it's no skin off your nose on a SIP line if 90% of the calls are just bots circling menus.
With the kind of software-defined telephony you hate, it's a cinch to just configure a little drag-drop GUI to handle filtering... known numbers through here, after two successful passes without complaints put them on the whitelist, otherwise send them through a phone CAPTCHA ("please press one-two-six-zero to proceed"), and if the receiver presses a special number mid-call, add the caller to the permanent blacklist. You just can't do that shit without software-defined telephony.
Software-defined telephony has nothing to do with most of the stuff you mentioned. And it's certainly little to do with why OTHER people aren't using their phones any more.
Telephony is a slow, inefficient medium for the basics of communicating information.
You want me to do something, or tell me something, email me. Text me if I'm mobile, but email will get through. It'll also all be "on the record".
If you don't want it on the record, I don't want to hear it.
At work I have an advertised direct line and I also get calls from a switchboard. I can summarise every phone call I get into a handful of categories:
- People who have techy problems who haven't emailled / ticketed them. Sometimes it's laziness, sometimes it's because they want to avoid admitting fault, it's NEVER because they couldn't just email/ticket them. - People I don't want trying to sell me things. - People I already buy things from "checking in" to see if I've happened to completely forget their existence, acquire several major and important and expensive projects, but just never asked them. - Convenience calls: "Your parcel is at the front desk", etc.
Personally, I don't even have a landline, because it was always just sales. My mobile phone, however gets these calls:
- People who don't know me.
Everyone else texts, WhatsApps, emails, Facebooks or whatever.
Voice calls are no good for remembering things ("Let me just write that down" / "Can you email me that number"), they are no good for conveying most information ("Send me the spreadsheet", "could you take a photo so I can see"), they take much longer to convey whatever information (which is an advantage if, say, it's a friend calling, but still much better to do in person), and they rely on you both being available to talk simultaneously to the point that one of you has to interrupt the other one most of the time.
Voice calls are an antiquity. It's like a hand-written letter. You use them to "feel", not to communicate. And most use of them is with people you don't want to "feel" with. That guy at Dell might want to generate a rapport with me, but I don't want that.
And the only calls I make are to "feel". Either express my frustration at lack of service, talk to friends, etc.
You have to be a dickhead not to have a backup of anything you rely on, though.
If you have a Visa, get a Mastercard too.
P.S. All the ATMs still worked, so you could... just get cash out. P.P.S. It was mostly contactless that didn't work. Chip & PIN was fine. P.P.P.S. Living day-to-day such that your dinner relies on you buying it now rather than "Oh, well, I'll have something else" is another "not enough redundancy" problem.
Gosh, if only there were other volcanoes around the world we could use to compare its output with, or monitoring stations all over the world's volcanoes for all kinds of gas analysis?
You know when you "recycle" all those old fridges and freezers.
And it costs a bucket to throw them away.
And then a market starts up around a slightly cheaper way to do it.
And the company just takes your equipment, ships it abroad, to someone who just signs off that it's being disposed of properly (but who doesn't care because it's not his life he's hurting).
And then the abroad country, not having any care at all for such things as they get a nice backhander to bury a bit of rubbish, just throws it in landfill..
Yeah... there. That's where I'd start.
Like when you GPS-track waste electronics and find out it almost all ends up in landfill in India, China, etc. and isn't even processed at all.
Maybe if you ever actually visited the UK, you'd realise that what you say is bollocks and most people live quite nice ordinary lives without cameras except where you'd want them.
I drive 20 miles to work each morning (hey, I live inside London). There are precisely two speed-activated cameras en-route.
By comparison, my workplace has - of its own accord - installed 36 cameras over two sites just for basic, private security, though (i.e. nobody watching them... just there in case something happens to reel back... I know because the controller box is in my server room and only I have access). Technically, my own flat has more cameras in it than my commute to work.
P.S. My neighbours were concerned about my legally-required CCTV monitoring stickers and asked to see my system, that's how uncomfortable the average person is with such monitoring.
Come to the country you're disparaging and see how accurate your bullshit is before you spout it.
We have one plate, on a car, it stays on that car pretty much for its life.
You then pay "road tax" (not actually true, but that's what it's called by people), online, verified with your recent vehicle test results, that you're insured on the insurance databases etc. and if you fail to do so, any police car with ANPR will flag you as you drive past, certain places (like London's congestion charging zones) will check your plate as you drive through, any traffic warden knows you're not up-to-date, and your car can be towed away.
No stickers. Nothing to "steal" / "forge". No new plates. No chips inside plates. No offline process necessary (but you can still do it in any ordinary post office like for the past 50 years).
I thought America was supposed to be at the forefront of technology and progress?
"Shit, people are beginning to ignore our complete monopoly of every diamond mine in the world and we don't want to show that diamonds aren't all that rare, and actually aren't worth anywhere near what we pretend they are (only enforced rarity causes that), so we can't just drop prices of 'natural' diamonds, so invent we'll sell fake diamonds with the same name at a reduced price to capture that missing bit of the market that can't afford our vastly-inflated made-up prices".
Honestly, fuck 'em.
How the various competition authorities manage to ignore them without even a hint of irony is just beyond belief.
I hope when someone starts mining asteriods and other planets that we find so many diamonds that they basically can't own them all and go bankrupt overnight as everyone realises they can now be sued into oblivion because they can't backhander the world.
A standard solar panel produces about 250-300W per square meter in such regions. Therefore you'd need about half your roof space to cool just one room, and nothing else. Call it a two-storey house (upstairs and downstairs) and you can *just* about cool the house if you do nothing else with it.
"As of January 2018, the average cost of solar in the U.S. is $3.14 per watt ($37,680 for a 12 kilowatt system). That means that the total cost for a 12kW solar system would be $26,376 after the 30% Federal ITC discount"
You would literally be spending something on the order of $35k just to cool your house. That's an annual wage. If you can't afford the air-con (notice that the article is just as much about "poorer countries can't afford air con, hotter countries cost even more to air con), $35k on top of the investment to power it is a huge amount.
That would buy 437,500 KWh of electricity in India, for example, which would keep that same 12KW powered for.... 99 years.
What you're asking is "Why can't people just spend 100 years of their cooling electricity usage in one hit so that they don't have to pay for any more cooling? On top of the price of the cooling system, and not including maintenance, replacement, fitting, etc. of either."
And yet, people in hot countries don't really have air-con according to this. What does that tell you?
It tells me that humans adjust to the environment with enough exposure and training (or they shouldn't be there at all), and that $20bn would be much better spent on something useful.
The fact that they know what happened to this level of detail means that it's always recording and they can go back to their records far enough, even days later.
The statistics are that there are an insignificant number of self-driving cars on the road.
Even if you include things like the Tesla which are NOT SELF-DRIVING.
Sadly, you won't have the statistics to compare accurately until, say, 5% of people has one of those things. Currently... what? SALES of electric cars are 1% of all new car sales. So there is an insignificant percentage of those, even, currently on the road.
If you took all Teslas, every single model of them ever sold, adds up to about 300,000 cars. Worldwide. There are approximately 1bn vehicles in the world. That's 0.03%.
If you go for "certified self-driving cars in private hands", the figure is so near zero that's is not even recordable. Everything is either a "prototype" from a big corporation or deliberately advertised as NOT a self-driving car.
So... sorry... self-driving cars do not have any statistically-significant data from which to draw any conclusion whatsoever. Even Tesla's don't.
As an IT guy, I fail to see why a computer would be any better than a human at such a human task. If we were talking isolated, self-driving-only roads, no human drivers, changing the roads to prevent such signage and road-marking confusions etc. Sure. We call that a railway, though. It's very different.
We couldn't even make a burger-flipping robot that works around humans. Robots/computers are good for one thing. The same task, over and over again, which needs as little interpretation as possible, and no human interference. Anything else is a mess.
And guess what a self-driving on an ordinary road is.
Which suggests that all those people who "only" buy the $35k model (expensive for a car, still!) are second-class customers whose business alone can't sustain the company, whether or not they are early adopters, first in the queue, etc. etc.
You shouldn't be using CAR SALES to pay for the CAR ASSEMBLY LINE. That's what all those millions in investment were for.
Your previous products pay to make the next. You don't pay for your current build facilities from sales you're only just making from them. That's called "living hand to mouth".
The dictionary definition of that phrase:
"satisfying only one's immediate needs because of lack of money for future plans and investments."
There's a reason that things like pyramid schemes are illegal. You can't take from tomorrow to pay for today. The closer you get to that, the more likely your business is to fail, and the less capable at running a business you are.
P.S. For Shor's algorithm: "For a 1000-bit number, this implies a need for about 10,000 qubits without error correction." - to give you an idea of what it would take to (probabilistically, not perfectly) factor one number.
Now imagine what it takes to crack a bog-standard SSL key, say. Most websites are already using encryption which will need a quantum computer 100-1000 times larger than anything that currently exists.
Not without a MUCH MUCH MUCH larger quantum computer.
We combat existing brute-force by requiring too much TIME to test all the possibilities.
Under QC, you'll combat brute-force by requiring a quantum computer of such impractical size that it would be infeasible (it's very hard to make a large QC that isn't susceptible to noise and quantum decoherence).
It's quite easy to make a prime-factorisation QC... in 2001, IBM built 7 qubits - enough to factor the number 15. It then took 12 years to advance the technology sufficient to factor the number 21. 2018's record so far is a 72 qubit machine.
By the time we get to factorising primes of the size used in encryption, it is instantaneous game-over for all standard cryptography. But it's a way off. At the point, we'll be glad of any increase in complexity that happens, and hashes are one way of providing that extra complexity. (Because the problem can't just be broken down into bits - you have to have an entirely coherent system to solve the problem).
And the way to combat that is to introduce so much complexity in the required machine that it becomes infeasible to construct (or even power!). We're talking literally millions of qubits.
Sure, 50 years from now we might all have a million-qubit computer in our pocket. But at the moment, post-quantum stuff is about making it so infeasibly expensive, impractical and difficult to make the machine capable of "instantly working out the answer" that you're safe.
They were hoping to use it for long-range drives (e.g. Voyager etc.) to get a "cheap" push to allow them to reach ludicrous-speed.
But it likely won't work in space, or near most planets at all. And likely won't be strong enough to accelerate or stop ANYTHING on its own.
Sure, once in orbit, you MAY be able to push yourself out... and then you're stuffed. But the weight of the engine + the power required to do that wouldn't be worth it if it has to be launched normally anyway, and has to have alternate power for the vast, vast, vast majority of its trip.
Also... inverse square law. If it's based on magnetic fields, and works only barely on Earth, you wouldn't get far away from Earth before it's literally useless.

"autonomous Uber SUV" "did not stop because the system used to automatically apply brakes in potentially dangerous situations had been disabled"
Then it wasn't autonomous at all.
So even advertising it as a "self-driving" or "autonomous" car, even for a test, is a huge amount of fraud.
"human interference"
Yes. On the back-end.
Google has been excessively easy to game for keywords over the years and required human moderation.
There are literally news articles about Google being gamed by people to hijack the searches for, say, certain politicians etc.
Not to mention the "French Military Victories" one.

Sure, once in orbit, you MAY be able to push yourself out... and then you're stuffed. But the weight of the engine + the power required to do that wouldn't be worth it if it has to be launched normally anyway, and has to have alternate power for the vast, vast, vast majority of its trip.
Also... inverse square law. If it's based on magnetic fields, and works only barely on Earth, you wouldn't get far away from Earth before it's literally useless.
