a) Has anybody planned a car where the autopilot doesn't have an on/off switch? b) Drivers don't get to look out of the window at the landscapes, they're too busy driving. c) Teslas have a Ludicrous mode which is a big selling point - they're more of a drivers car than anything else you're used to.
Maybe this stat will be relevant when there 10s of millions of electric cars 10-15 years old without adequate maintenance.
I can't imagine the number of spontaneous fires from car batteries will be very different than for all the inadequately maintained laptops and smartphones out there.
Are these reporters pointing out that 17 gasoline cars burst into flames every hour in the USA? That non-Tesla cars are responsible for 6% of all fire-related deaths?
Even for 128 bit crypto: sqrt(2^128) is still a very big number.
It's possible to brute force 2^64 using vast amounts of conventional computers but conventional computers are cheap/small/easy to power. I doubt anybody will be running anything like the same number of quantum computers in parallel. Not even sqrt(conventional).
and, b) It hasn't yet been demonstrated that Quantum computers can be programmed to efficiently crack conventional crypto. It's actually very unlikely that they can - quantum algorithms are very limited in what they can do.
b) We already have 256 bit block ciphers. sqrt(2^256) is impossible even on a Quantum computer.
Quantum computers can potentially reduce the amount of operations by the square root of the search space. So if you have a 64 bit key, it's now a 32 bit keyspace you have to search through.
You have no idea what you're talking about, do you?
You've got all the right words there, but completely the wrong concepts behind them. You do realize that ALL of the data shipped around via HTTPS is encrypted with symmetric algorithms, right?
It's almost as if you don't know that HTTPS relies on signed certificates for authentication...
Why would they sell their data? They don't want anybody else to have it.
If you pay them enough they might promise to show your adverts to some relevant users of their products but there's no way they're going to anybody a zip file full of user data.
Will blockchain stop them from lying about "We went to your house and you weren't there" whenever they can't meet their 48-hour delivery garantee?
If not then what does this actually help? Are they going to make their ledger public domain and pay tens of thousands of non-Fedex miners to work 24/7 on the signatures to make sure there's too much external computing power for a Fedex employee to be able to falsify any information.
Because if not... "blockchain" is just another buzzword that a manager is using to get himself a new office.
It turns out that you can make some sales by solving people's problems instead of just spending all your time trying to trick/bludgeon them into using your Internet browser and search engine.

Huh?
a) Has anybody planned a car where the autopilot doesn't have an on/off switch?
b) Drivers don't get to look out of the window at the landscapes, they're too busy driving.
c) Teslas have a Ludicrous mode which is a big selling point - they're more of a drivers car than anything else you're used to.

How about this -- 65% of all fires in waste facilities are from lithium batteries.
Those places where they pass lithium batteries though big grinding machines followed by even bigger trash compactors?
Yes, that statistic might be true.
Get back to us when there are a statistically significant number of Tesla cars on the roads, you shill.
Huh?
The whole point is that there aren't a statistically significant number of Tesla cars on the roads but they're making all the headlines.
2000 gasoline gars explode? Nothing to see here.
A story involving a Tesla? Front page news!
The single greatest thing about self driving cars will be that the police can order the "bro-types" to use one after a driving offense.
The future of motoring laws won't be "banned from driving for six months", it will be "forced to use autopilot for 2 years".
Are these reporters pointing out that 17 gasoline cars burst into flames every hour in the USA? That non-Tesla cars are responsible for 6% of all fire-related deaths?
Nope? That's what I imagined.

We can safely ignore this headline.
In surveys people think Facebook is evil but I don't see many of them cancelling their accounts.
Surveys also prove that people want more leafy green salads in McDonalds but nobody ever eats them if they appear.
Nope. The day people figure out they can use Facebook all the way to MacDonalds and back will be a good day to look for a second hand car.
No need to include the original packaging either, which is handy because it often requires destroying to get the product out anyway.
Whenever I buy something speculatively (which I do occasionally) I always make extra effort to not destroy the packaging.
If it comes with a separate mains cord I'll normally use one of the dozens of mains cords I already own to test it instead of the one in the box, etc.
If it goes back, it goes back just the way I received it (or as close as I can get).
If a cipher is vulnerable to a known plaintext attack, it's utterly broken and unusable. This is how cryptographers see it, and for very good reasons.
And c) All algorithms are vulnerable to known plaintext attacks - even one-time-pads (which are the only provably secure crypto).
Even for 128 bit crypto: sqrt(2^128) is still a very big number.

I bet she could come up with some political jargon that you wouldn't get but every politician in the room would know what she was talking about.
The sqrt(N) thing only works for known plaintext attacks.
If the message is salted with a random number then it becomes much more difficult.
Quantum computers can potentially reduce the amount of operations by the square root of the search space. So if you have a 64 bit key, it's now a 32 bit keyspace you have to search through.
Only for known-plaintext attacks.
It wouldn't be instant, it would be sqrt(todays_time);
You have no idea what you're talking about, do you?

To be clearer: Quantum computers break things based on number factoring, eg. certificate signing.
It doesn't break block ciphers like AES.
It might break blockchain, yes, but, like, who cares?
The idea that activists are stopping you creating this magical solution to climate change because they're focused on use of CRISPR reeks of bullshit.
What sort of idiot wouldn't want CRISPR lettuce?
you've surely seen the statement that if a business isn't selling you their product, then you are the product.
A bit like Slashdot, then?
I want to know how two dozen Excel spreadsheets is "roughly the equivalent of a high-quality photo snapped on my iPhone".
I'm not sure anybody who writes sentences like that is qualified to judge what Apple is up to.
Why would they sell their data? They don't want anybody else to have it.

A blockchain is simply a ledger.
...a ledger that needs a large enough number of independent people working on it that nobody can get together enough computing power to falsify it.
With Bitcoin you get a reward for "mining". What will Fedex give people to make them bother donating their CPU to the FedEx cause?
Aaaand blockchain helps, how, exactly?
Will blockchain stop them from lying about "We went to your house and you weren't there" whenever they can't meet their 48-hour delivery garantee?
If not then what does this actually help? Are they going to make their ledger public domain and pay tens of thousands of non-Fedex miners to work 24/7 on the signatures to make sure there's too much external computing power for a Fedex employee to be able to falsify any information.

Imagine that!
This Core i3 8121U chip has a TDP of 15Watts.
So... a bit like the Atom CPUs then.
Move along, nothing new here.
