I seem to recall that the ones I've opened have made from pretty nonmagnetic materials, so it's not closed. The field is strongest in the gap, sure, but there's plenty of field leaking around it.
It is possible to reread some data from a zeroed (or oned (sp?)) disk.
No, this is mostly a myth. There is no known instance of anybody doing this, especially not with a modern hard drive with the insane data density they have these days.
It's highly doubtful that even a government agency could do it. Certainly nobody is going to be doing it at home, not at the kind of data densities you have on modern drives.
You do know that hard drives have extremely strong magnets sitting a couple of millimeters from the platters, right? You're not going to get a strong field than that out of anything outside the casing short of an MRI machine.
If global warming can be mitigated for less than the cost of reducing greenhouse gas emissions
It can't. Geoengineering can only mitigate the symptoms, and likely only for a while. It gives us more time to solve the actual problem, but that's all it does.
Because that money doesn't disappear from the economy, it circulates? And more money circulated means a stronger economy? Especially since oil profits leave the country, while wind or solar profits wouldn't?
Because more expensive energy means more researching to energy efficiency, driving industry forward, leading to a stronger economy?
Because energy sources don't have static costs, but depend heavily on the amount of utilization and research and development put into them?
Yes, that's the problem with cutting emissions, and which is why we might need an alternate plan that doesn't require everyone to agree, like geoengineering.
Yes, all that extra research and development, and all that spending on new technology sure is horrible for the economy. The economy is strongest when nobody uses any money for anything!
Tell me again how buying a new Prius (for example), which takes a massive amount of energy to create (mining/refining/machining/assembly/and shipping at each step of the process) reduces the total amount of emissions the world produces?
Because it takes less energy to create it than it saves over its lifetime? This isn't exactly rocket science.
Well, you nearly have that already. Sunlight is much closer to the bluish-white LED light than to tungsten. (Tungsten is around 3000K, sunlight is 6500K, white LEDs are around 8000K.)
I've got a nice, tungesten-coloured LED right here that emits nearly omnidirectional light if I just remove the lens that comes with it. I don't think directionality is really any kind of inherent problem, just a manufacturing issue.
As a libertarian, I'm not quite sure what you would mean by an extremist libertarian;
Then you seriously need to take a much closer look at yourself and your compatriots, because you seem to suffer from quite a serious case of tunnel vision.
Sounds like you got a larger than usual dose of The Internet in there. It can get pretty caustic when concentrated!
Seriously, you'll see the same thing happen anywhere where self-declared smart people congregate. Slashdot gets some of it, reddit gets even more of it, and so on. I can see why Bruce would just want to get rid of the whole mess, if it got that bad.
Slashdot Mirror
Drive were quite a bit different in 1996.
Plus, skimming the text I see no references to actually doing what is described. I case I just missed it, please help me find it.
It is definitely doable
If it was that easy, then the manufacturers could just make the drive bigger instead. It simply doesn't work like that.
Unless you know of a documented case of anyone doing this, ever.

I have a heavy duty magnet too. It sits right inside the harddrive next to the platters, just like in every other harddrive.

put some web sites being trashed in the same category as bombs and missiles flying around.
Who exactly is doing that? I'm not seeing it.

Because it's not a long-term solution? You can only dump so much iron into the ocean.

Geez, with problems that severe, it's a wonder anybody would use them!
It's the hip new anti-environmentalist meme. Anything that is supposed to lessen emissions actually increases them because you have to build it!
There are LEDs with very tungsten-like spectra. They're just not very common yet.
I've got a nice, tungesten-coloured LED right here that emits nearly omnidirectional light if I just remove the lens that comes with it. I don't think directionality is really any kind of inherent problem, just a manufacturing issue.
What the heck is up with the h.264 hype?
Higher quality at lower bitrate? Is there something about that which is difficult to understand?
I would base extremism on when people use force or threatening others to pursue their purpose.
Perhaps you would, but that is not the definition of the term as accepted by others.

YOU ARE EDUCATED STUPID
Acadamia never ceases to amaze me. Note, spelled wrong on purpose BECAUSE OF ALL THE NUTS!
That could be a funny joke, but you really need to work on your delivery.
