in his own car since that could fit the pressure cooker in the back seat.

Sounds like pressure cookers really have gone out of fashion, if people think they are that big. Hint: only slightly larger than a normal pot.

Think about it: if it fits into a backpack (he!), it fits into the trunk of any car, no matter how small.

I think GP meant, "why should the e-commerce site care, after the customer has already left his money on the table".

The correct answer would be "the repeat customer", but maybe those sites that are pulling such stunts deliver such shitty service or merchandise that it would be highly unlikely that a customer ever came back, even if the checkout page loaded faster...

If that were the case, the mountains would actually need to displace less of the heavier mantel material than they otherwise would (because part of the load would be absorbed by the crust around), so a hypothetical observer standing on a mountain would still observe more mass beneath him than his colleague standing in a plain.

The only way it could work is if actually the plains were "supported" by the mountains rather than the other way round, but that somehow sounds unlikely...

More mountain = less mantle = less dense.

So, in a way, it would behave light an iceberg floating on water. However, what I don't get is why there's less mass beneath, rather than equal amount. Indeed Archimedes stated:

Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object.

It acts as an additional requirement to logging in to a computer, cellphone or network beyond a password.

Actually, it supplies the password. When you plug it into an USB port, it acts as a keyboard, and "types" a one-time password as soon as you touch its button.

One of the main security features of tokens of this nature is their inability to be tampered with since it is guaranteed to be connected to a computer.

Huh? How does being connected to a computer guarantee that it is tamper proof? Or is that the other way round?

The YubiKey Neo was potted in a plastic that melted totally in nail polish remover
The fact that the plastic can be removed so easily

Actually, methinks the issue here is poor word choice. Yubi should have touted their product as "tamper evident" rather than "tamper proof".

For its main application, tamper evident is enough. If some ill intentioned third party wanted to read the seed from the Yubikey's chip, they can, but it will be very obvious to the owner that this has been done (casing is gone), and so the owner can have his key blacklisted by his provider (making the seed worthless for the attacker).

Oh, an if you're worried about a "fast" attacker that uses the pilfered credentials immediately, rather than sleeping on them for a while: he can achieve this much easier by just stealing the yubikey, and using it normally, rather that bothering to dissolve its casing first.

along with a poor USB connector and keychain loop disprove YubiCo's claim that the YubiKey Neo is "virtually indestructible".

Good point on that one. Accidental destruction (causing hassle, but not a security issue) is indeed a real concern with the device.

Since the original question is what devices will keep working without humans present then the correct answer is likely satellites, but those are not forever.

... and even if a satellite stayed in place forever, they wouldn't stay operational that long. In less than twenty years, all its transponders would go silent, and it would just be an inert mass, just like my roomba without electricity and a full dust pan.

Not in Geostationary orbit. They will be there "forever", they may still work for a long time, but eventually debris impact and radiation will kill them.

Nope. Even geostationary satellites do drift, and need "station keeping manoeuvers" to keep them in place. Especially the colocated ones (more than one satellite in one orbital position).

And the commands to perform those manoeuvers are sent manually, from ground.

satellites would fail quite quickly as their reaction mass ran out or their reaction wheels failed...

Actually there's no reason to believe that their reaction mass would run out more quickly than with humans still present. The contrary would be true: no ground station to send station-keeping commands, and so no consumption of reaction mass.

But they might end up bumping into each other, or spiraling up or down out of their orbits eventually without any commands to keep them in place.

In Belgrade, Serbia, I can phone a taxi and request a ride.

Actually, not just in Belgrade, but everywhere where there are taxis. Or at least it's the case in Europe (personally used this in Metz, Toulouse, Berlin, Luxembourg), not sure about the United States. Reliability can vary though (stiffed by a taxi in Metz).

Yeah, you're "free" to have to do 365.25/365.25 on call. While needing the money more than your boss needing the help. Because if you go, there's 50 more lined up to take your position.

But you dont't have 50 more potential bosses to work for, and the few "opportunities" that do exist would impose similar conditions...

Meanwhile, being on call 24/7, 365.25 (this includes every fucking weekend, and every fucking holiday, and every fucking vacation -- no matter how remote) is a recipe for employees (me) finding ways to avoid it.

That's why in the free world, the law says that one given person can't be on call all the time. You are supposed to rotate this duty within the team, so that every week it's somebody else. And the one who's on call gets extra compensation for it (just for being "ready", even if during his period, there happens to be no call).

Dead? No excuse for laying off work.
