Why not just mix in consensus-control, artificially generated disengagements?

Even if the system has high confidence in its ability to handle a situation, if sufficient time has passed, request the driver resume control.

Then fusion the driver's inputs w/ the system's for either additional training data or backseat safety driving (e.g. system monitoring human driver).
It's still quite possible to be a completely legal asshole. I'm surprised this is news.
> In your original post, the first paragraph made you sound like a crank. You said the paper is like breaking the speed of light, but you don't even mention the topic of the paper. I almost stopped reading at that point. Similarly for the sentence towards the end saying that this is "crazy important". People can decide that for themselves. They can decide even better if you put stuff into context.

I literally mention the TITLE of the paper, itself precisely explaining its domain & method, directly after the statement and end it with a semicolon.

Let's be real here. The paper is a real dragon of a read. If you're not going to go past a single surprising sentence maybe it was pointless for me to mention it anyways.

> "Here is a surprising paper that shows that you can sort general data structures in linear time!"

I have done this twice, tried different tact twice more, and been downvoted or ignored every time. This is the new me, assuming that folks just don't know how their every artifice of computation is backed by sort. And I suppose... why would they? A great many people simply skip even the basic theory of computation as they join the industry now, and maybe that's okay.

But I say it precisely as I do to generate shock. It should be surprising. I've caught people interviewing for principal engineering positions at Google and Amazon off guard with this. It's very, very surprising.

That sounds like anything but an advantage if you eventually seek to have children be independently capable and willing to rely on their own resources.
Be sure to judge them for that, too. This forum exists because of money spent by people on their phones all day.
Instructed by whom?

I'm kind of reminded of the stories of Chinese road traffic accidents where the advice is to make sure the victim is dead - reverse over him if necessary - rather than any other outcome.

UK law very definitely requires you to stop shooting immediately once the danger is past - see R v Clegg.
Typically, a digital chip such as this is designed with Verilog (or VHDL in europe) for RTL. Most hardware compilers then also provide test vectors (for registers and logic) and built in boundary scan through SPI. When contracting the chip your in-house design software then generates GDS (semiconductor mask design format) which you provide to the vendor. Even without obfuscation, it would be enormously difficult to reverse engineer enough of the design to pass the boundary scan test vectors. Certainly, after manufacture you can decap and check that the product matches the mask.

There are various extra design and production steps I'd go through for crypto verification and test, but it would be difficult to fake a chip if they allow verification after SMT on the PCB. After that, physical access and fairly sophisticated methods could bypass it, but you're already trusting TehGoog... so NoSuchAgency shouldn't be your concern.
You're right, but it's a totally irrelevant fact that other people will still judge on.
Thanks for the correction, I was wondering when I would have to burn a namecoin or something.

> IPFS and the Blockchain are a perfect match! You can address large amounts of data with IPFS, and place the immutable, permanent IPFS links into a blockchain transaction. This timestamps and secures your content, without having to put the data on the chain itself.

While I'm at it, I should also mention the caveat that IPNS won't put an entry into the classic DNS system, so you won't get a yourdomain.com out of it. It just gives you a random permanent base62 name to refer to some updateable content. You could ameliorate that for yourself by running your own DNS service, and I actually like the idea of that - I'll name things for myself as I see fit.

> even private citizens who are armed and are using it in self defense, are instructed to shoot to kill only

That's not because of the legal ramifications, though. Shooting to wound is very very difficult especially in a crisis. The limbs are much smaller targets than the torso and move much more rapidly and unpredictably. Additionally, they are trained to keep firing because even lethal gunshots tend not to be immediately incapacitating. Due to the effects of adrenaline, people can continue fighting even after being shot in the torso a half dozen times.

In short, guns are terrible non-lethal weapons.

Has it ever taken 8 years to send something to the moon?
I'm glad you asked! So there's an important physics reason why the equator is warm and the North and South poles are cold on this planet, and it has to do with how you point a surface. If you ever find yourself in a dark office with a bright desk lamp (or maybe your home office or kid's bedroom might be suitable) you might even try this experiment: take a flat surface, a notepad or steno pad, and hold it up facing the light source, then slowly tilt it away and look at the color of the surface; you'll notice that it doesn't sharply transition from illuminated at 0 degrees to dark at 90 degrees -- instead it smoothly varies like the cosine of that angle.

This mathematical effect is incredibly important, it means that sunlight, during the day, averages out to being half as strong as its maximum over the whole of the Earth's surface. The calculation isn't even particularly difficult: the surface area of a sphere is well-known to be 4πr², half of that or 2πr² is illuminated at any one time, but the actual irradiation that we receive is proportional to the cross-section area, which is just the area of the circle: πr². So if the Sun-directly-overhead light were to be illuminating that entire half of the world, we would get k·2πr² light for some k, but instead we only get k·πr² light for that same k, so it works out to be 1/2 when averaged over the whole surface of the Earth.

While I was at university a fellow student asked me to guess the coldest place in the Solar System. I guessed "the middle of the dark side of Mercury." I guessed this for a couple reasons: (1) I knew I needed a rock without an atmosphere since atmospheres sustain convection currents that transmit energy, and (2) I figured since Mercury is so close to the Sun it's probably tidally locked to the Sun and therefore this part probably has not seen a speck of sunlight in millions of years.

It turns out that general relativity makes point #2 wrong and my friend gleefully informed me that he was looking at an article (there were many, so let's take [1] as representative) suggesting that it might be in a crater on the South pole of the Moon. This has basically the same reasoning of (1) and (2) above, except substituting the shadow of a crater for the shadow of tidal locking. But Mercury is still in the running -- the only issue is that we might not be looking at the dark side of it, but rather, again, at its poles.

Ruby does something similar, but all Fixnum (native sized) values are 'fixed objects':

a = 2**62 - 1
b = 2**62 - 1

a.object_id == b.object_id # true

a = 2**62
b = 2**62

a.object_id == b.object_id # false

Ruby does automatic promotion from Fixnum (native size) to Bignum (arbitrarily large) and uses one bit of the native size as a flag to identify this which is why 2^62 - 1 is the max instead of 2^63 - 1. Though I think this is only true of MRI and other implementations handle it without the flag bit.

Perhaps one difference from Python is that in MRI Ruby Fixnum doesn't really even allocate an 'object', the object_id is the value in disguise. In fact all 'real' objects have even object_ids and all odd object_ids are integers:

a = 123456789
(a.object_id - 1) / 2 # 123456789

You can do what they did for L. Ron Hubbard's doorstop-ology "Mission Earth", where they'd buy the books in stores, give them back to the publisher, and buy them from the stores again.

Cars are just computers with wheels, and are bound by similar restrictions. So let's amend the scenario:

The car you bought gets in to a car accident because of software running on the car, which is licensed to you in similarly revocable terms to the shrink wrap currently on the market.

Both this software and React are software licensed to you in this case, should you be legally disallowed from ever purchasing a car from that company again? What if it's a cloud service that powers the car in some fashion which you want to sue over?
Yep — Pathfinder and the Mars Exploration Rovers (Spirit & Opportunity) both used airbags.

It's very natural for lower income regions to strive towards higher incomes when they are used extensively for production. It's a process many eastern countries have gone through, and, as a result have become "unsustainable" to host manufacturing sites. I write unsustainable in quotes because those higher wages are certainly not unreasonable; but as long as there is a cheaper option, enterprises will keep moving on.

So, Slovakian workers are now realizing their current leverage, they might actually receive raises, but soon auto companies will move on. Auto co shareholders want their company's suppliers to squeeze every last penny out of every part, haggling over 0.5 cent savings is really normal.

> The universe doesn't care.

And that's exactly why it's important.

> Survival of humanity isn't important universally.

Unless there is something there that cares about it, there is little reason for the universe to exist - nothing would know the difference.

Which is why it actually is important universally.

> But it's the most important thing for humans.

No, it's more important for the universe to have humans, than it is for humans to have a universe.

If the universe did not have humans (or another sentients) then it might as well not exist. AKA: Humans super important to the universe.

If humans did not have a universe, then humans would not exist. If humans did not exist then nothing is important to them.

I recently drove an Accord with lane-following and speed adaptive cruise-control recently. It completely failed (but thankfully by refusing to try) in the one instance that I wanted to use it (stop-and-go traffic), but it was nerve wracking when it was on as it kept losing the lane. People naturally alter the throttle and speed when going around corners and up slight inclines. It feels alien when that doesn't happen.

I can't say I have had much success explaining my thesis clearly to anyone except people from the same department, but I can try to give my understanding of discrimination from an implementor's perspective.

The succinct version is that all (discrete) data can be serialised as bit strings and those bit strings can be sorted in linear time by (say) radix sort.

There are two ideas at work here: that all (discrete) data structures ultimately are composed of primitive types that can be sorted in linear time, and that we should only examine each primitive value once.

However, to be fair it should be mentioned that the analysis uses a different machine model (the RAM model) than is usually employed in sorting (where all comparisons are considered to take constant time, which is arguably an inferior model of real computers if you are sorting e.g. strings of variable length).

To be honest, though, the original paper is so well-written that I have a hard time explaining it better.
