The power transformers aren't sensitive at all. It's the 1000 km transmission lines connecting to them that are. Your pc is not connected to those lines.

No, I can't. The Weather Service, however, does a damn good job with their five-day forecasts. They don't always get it exactly right but they do well enough that I can confidently plan when to cut my hay.
It isn't 1965 any more. Weather forcasting works. Even the ten-day forecasts are accurate enough to be useful.
> So would something like an EMP destroy pace makers, artificial hearts, etc.?
Sufficiently intense EMP could do that, yes. But this is not EMP. While the energy delivered over a large area is enormous the rate of change of the magnetic field is not high enough to induce damaging currents in small objects. You can think of it in terms of energy density. The field fluctuations can have trillions of joules of energy but they are the size of continents. Thus they can easily destroy continent-sized structures such as electrical distribution networks but not deliver enough power to the few cubic centimeters occupied by a pacemaker or cellphone to damage it.
Alternatively, consider the wavelengths involved. Because of the slow rates of change of the field the energy is all at frequencies such that the wavelengths are many thousands of kilometers. These couple fairly well to thousand kilometer transmission lines but not at all to the one centimeter wires in your 'pod. .

Just listen to the yammering for five minutes and then interject comments that are a rehash of what the others have already said. They'll never notice that you didn't see the shows. They aren't there to listen anyway, just to talk.

Why would you ever put any correct data in to begin with, except for stuff that is already a matter of public record or that you see no reason keep private?
Even if Facebook could be trusted to keep your secrets your "friends" cannot.
Last year the USA exported about a million dollars worth of goods to North Korea. Trade with North Korea is heavily retricted by regulations intended enforce the UN sanctions but it is not entirely banned. See North Korea .

Where else is most of it going to go? The part of the planet over the horizon from the explosion (i.e., almost all of it) is shielded by the planet.

Half of it does. Unfortunately, the other half gets radiated downward to the surface.

You are saving a few people from being converted to glowing plasma at the price of subjecting most of the residents of an entire continent to third-degree burns.
Yes, with a little scripting. It would have one insurmountable drawback, though. It would not be integrated into Active Directory/Sharepoint/IIS etc in such a way as to lock you in even more firmly and require you to buy another $100,000 worth of licenses.

Why, when you can use the problem as justification for collecting more money?

Give them to me. I'll see to it that they are ok (by doing nothing in particular: they are not at risk anyway).

That's exactly right. Most of the world takes only two things seriously: sex and murder.

More like the square of the length of wire.

Yes, but that doesn't matter because Perl is out of fashion.
Or worse, they do.

Yes. The government is paying most of your tuition.
I've heard that it has a nicely finished basement.

I suspect that what is going on here is that they only count responses from users within the "service area" of each station.

Or go back to your desk and get some work done.

Not owning a working receiver does the job quite well.
Take "mash-up of stuff found on Google", add ten pages of citations and references, and you've got an academic paper.

How many of these universities or Fortune 1000 companies have published studies of the effect of this technology on energy savings in their networks?
This is not true in all jurisdictions.
Yes, with a little scripting. It would have one insurmountable drawback, though. It would not be integrated into Active Directory/Sharepoint/IIS etc in such a way as to lock you in even more firmly and require you to buy another $100,000 worth of licenses.
Interesting. Could we have a link, please?
I was expecting a sleep proxy for me so that I could stay up all night while the proxy wasted time sleeping.
