The problem with no-forwarding is that people who want to forward the message anyway, by definition turn into non-cooperating people. You might as well just add a text "please don't forward".
Non-cooperative people are only one category of people who'd forward mails even though told they should not. Another large category are users that are just ignorant, as in what does forward mean?, and what's the difference between this reply button and that "reply" button?. For those, a cooperative "Disappearing" system would indeed help (whereas a friendly plea to not forward would just be ignored as computer person's gobbledygook...)
Indeed. Same on some French TGVs. They have sockets for the express purpose of letting passengers charge their phones or use their laptops. It's crazy how you can get arrested in London for doing something which elsewhere is allowed and expected.
But to the PCSO's defense: apparently the socket was marked "do not use". Still a mystery why it was even turned on, if it was only for the cleaners' use while the train was stopped...
Having Googled "hairy mammoth" and visited a few search results, I've concluded I never want to Google "hairy mammoth" ever again.
You piqued my curiosity. So despite being at work, I took the risk and googled "hairy mammoth"...
... and I was quite disappointed that most text links were indeed talking about the "woolly mammoth" species, not something else. Ok, so I clicked "Images". Second disappointment: most pix were just hairy mammothes (you know, the elefant-like animal, not "bears", not Portuguese ladies or whatever...). 98% percent mammoth, with the odd (non-hairy, and non-obese) girl thrown in. Or are you using a different google than me?
O, and I did check that I hadn't accidentally enabled "safe-search"...
A resignation might look better than a firing to a prospective next employer. Of course, if the resignation or firing is in response to a well-publicized event that point is moot...
A nice story indeed, but utter bullshit. It has enough snippets sounding vaguely plausible, and similar enough to real facts, but assembled in a way that makes it wrong. To get info about the real deal about the A20 address line, check Wikipedia instead. Interestingly this wikipedia article is also linked from the "nice story" article.
Here's where the "nice story" is wrong:
The keyboard controller is actually located on the motherboard, and available even if no keyboard is connected. Its job is to talk to the keyboard, but it's not part of the keyboard itself
the A20 issue is not at all due to the BIOS memory test
Re-enabling wrap-around for real-mode programs doesn't involve any computing power anywhere. So, no need to find a co-processor that is "idle", you only need to find one with a spare I/O line
The real explanation for the strange error message is actually the following: "No keyboard (or broken keyboard) connected to the computer. How could anybody possibly use a computer without a keyboard? Please connect a (working) keyboard to the computer, and Press F1 when done".
It's still stupid, but for a different reason (servers don't need keyboards). That's why modern BIOSes allow you to disable keyboard check, if you want to deliberately run your computer without a keyboard.
I don't. I always have either Notepad++ or VIM installed on every machine so that I have a useful text editor. I haven't had to stoop to using Notepad/Wordpad for a very long time.
What if you work in a company or administration that doesn't allow you to install the software you need? In such case, you might well be forced to stoop to using Notepad or Wordpad for lack of a more sensible choice...:-(
Look weather might be chaotic but we can say it will rain next week,
... or even better: we are able to say with almost 100% certainty that it will rain sometimes next year (we're just unable to tell the specific days, obviously...)
So, even if some aspects of a chaotic system are not predictable (almost by definition...), others are.
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...
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.
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).
... how can a comment about the article (linked to in the summary) be off-topic? Is there even something which could be more on-topic that a commentary about the article?
(Even if it's just about a presentational aspect?)

Sometimes you say thank you and then call back hoping to get someone else.
If you already had to wait for 20 minutes listening to elevator music for this call, you think twice before considering that option... :-(

But the article clearly puts the blame on MinGW.
Not really...
He even gives links to the patch.
... and this patch makes MinGW use its own implementation of printf (and family...), rather than trusting Microsoft's buggy version.
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.

More mountain = less mantle = less dense.
