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.
Scanning of networks is allowed, but only their ground networks.
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.
And while reaction wheels do go bad pretty quickly (a decade or so)
With a "decade or so" the satellites would already be a handsome winner. Little other technology will survive for even a month without being powered or recharged.
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).
(Even if it's just about a presentational aspect?)
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).
We should name the diseases after politicians. Preferably members of the US Congress. They want the recognition.
They already do, in a way. It seems that santorum is named after a politician...
I personally would probably get one of those signal shielding bags and drop it in there when I wasn't to be on-call. Then you could carry it with you even. Then it also appears just as if it lost power for a while, so it would be hard to get in trouble over it...
I used to have a phone with the problem described in TFA, along with me allegedly being "on-call" at all hours.
Does "loss of signal" mean only "loss of GPS signal" or "loss of all signal". Indeed, if it's a phone, if it has no signal at all, and if you're on call, I can see where the employer might have a problem with this. And if you're not on call, go with the other posters more low-tech suggestions, and leave it at your desk...
