But that case was designed for the Kindle 2, which (I think?) *doesn't* put power across those pins. If that's the case, this is mostly a Kindle 3 design flaw - they should have made the slot spacing different so you couldn't use a Kindle 2 case.
Not as hot as you might think; most of western North Carolina is at a pretty high altitude and has quite moderate summers. Pre-air-conditioning, summer vacation in the Appalachian mountains was popular among upper class New Yorkers, so...
Well, maybe he's bringing along one of our prototype military lasers! There are solid-state 100Kw lasers in test that I'm sure will sink a wooden ship just fine...!

Take your file (A). Generate a block of high-entropy random data (B).
Now generate (A xor B), and throw away A. You now have two random files, B and (A xor B), and B xor (A xor B) will give you A again.
A cute variant: instead of generating a really random B, use pseudo-random data generated from a known key (mp3 rip of some song of a particular version of a CD, gzip of linux kernel source), and don't even keep B with you; regenerate it on the other side. There are lots of ways to screw this trick up, though, so consult a cryptographer.
You could use more than 2 files if you want, the idea is basically the same.
A lot less; it's not a coincidence that IBM never publishes any industry-standard benchmarks on these things.
Don't get me wrong; they're fast, but they're not magic, and they're not remotely competitive on a price/raw-compute-cycle basis. If that's what you want go get a beowulf cluster.
Short form:if P=NP, crypto is something of a futile effort - that implies that there's a non-brute-force crack to every possible private-key algorythm. I suppose it might still be slow enough for the crypto to be useful, but I woudl expect you would end up needing gigantic keys.
Most everybody assumed that P!=NP, but nobody has been able to prove it.
So, it's a Linux port that will only be usable by people who dual-boot? Good grief.
I bet you could hack together a workaround without massive effort; write a case-desensitizer FUSE filesystem, and have it 'remount' a case-insensitive view of an existing filesystem in an alternate path.
I think a tetrahedron, growing into a 8-sided d8 kind of thing, then back - a cube has six faces, but a hypercube has eight cubes for, er, faces (one on each end, and then a cube connecting the faces of each of those).
That's why we need to be more proactive; instead of trying to eliminate all the invalid keys, we should just pick the strongest possible key and standardize on it.
Yes, but the stuff hitting the mooon in the past has been all-natural, and as we know, natural stuff is always safe, it's that nasty artifical stuff that'll kill you.
The key point here is actually that it's an optical-scan machine! You don't input votes on a keyboard or touchscreen but by feeding in an actual human-readable piece of paper (maybe it asks for confirmation that it read it correctly?), which then gets stored in a lockbox. This is obviously the Right Thing because it gives a built-in hardcopy audit trail.
In short, I think we're missing the SuddenOutbreakofCommonSense tag on this story...
Oh, and it's worse than that. Even if you had the power, suppose charging Li batteries was 99% efficient (I think it's more like 90%??). So of that 300KW you're charging with, 3KW is being converted to heat inside the battery while your charging - probably several times that - and it's going to be tough to manage this without frying the battery even if you have the power.
Right now, every solar-panel production facility on the planet is supply constrained. Therefore, what NJ is doing is paying extra money to ensure that solar panels are installed in NJ, rather than in, say, Arizona, where they actually make sense without massive incentives and produce three times as much power.
I'm pissed at ATI for dropping binary support for FGLRX for Linux kernels later than 2.6.29, and was considering getting an Nvidia GPU in my next laptop, but now it looks an awful lot like Intel is getting my $50....
It was my understanding they had only dropped updated support for older cards (R500?), which are pretty well supported by the OS driver these days anyway, now that ATI is publishing specs again. Am I confused?
Exadata 1 was just preinstalled Oracle on HP hardware. Exadata 2 is essentially the same but with Sun x86 gear replacing the HP. Neither of these have the sort of numbers Oracle is promising here, and they've all but said it's Sparc. I'd guess it's a cluster of Sun T5440 (4 socket, 32 core, 256 thread) Sparc servers (which have very respectable throughput, despite marginal single-thread performance) with Oracle RAC and some sort of Sun disk array, probably with some kind of big flash/SSD component providing much of the performance boost.
Probably, but so was Linus in realising that Minix isn't actually useful, and wasn't on a path to become so.
In the end do it the only way it could have worked; backwards - shimming a microkernel underneath the Linux kernel and calling it a "hypervisor" instead, and nobody will notice it's the same thing...
You don't understand - this isn't about science, or space travel, this is about pork, pure and simple. NASA has turned into a jobs program, and easy cash for contractors based in the states of these key congressmen - to the point where now, despite their huge budget, they really can't do anything useful in terms of launch.
The Augustine commission pointed out that the whole current setup is an expensive disaster, but Congress doesn't want to hear it, because they're only interested in keeping the cash flowing to their districts and/or campaign contributors, and who gives a rat's ass if any actual science or engineering gets done?

No, no, no. For this, use a one-time pad.
What you do is this:
Take your file (A). Generate a block of high-entropy random data (B).
Now generate (A xor B), and throw away A. You now have two random files, B and (A xor B), and B xor (A xor B) will give you A again.

Actually, I believe it does now. 3D driver support is even worse than Linux, though. :)
I've read of people trying to sell this in Iceland - cold, and you have cheap geothermal power!
They were having trouble finding users who weren't turned off by the expensive bandwidth, last I'd heard...

This is a key point; for all we know, he did 9 other tests that showed no signs of irregularities and published only this one!
Suspicious? Yes. Smoking gun? Not even close.
Yes. Chip plants may use a lot of water, but it's a drop in the bucket (so to speak) next to farming.
So, it's a Linux port that will only be usable by people who dual-boot? Good grief.

Not at all sure, though.

It turns out that the most efficient type of stimulus spending is spending on studies of stimulus spending.

More likely an Exadata 3, or 2S, or something.
Exadata 1 was just preinstalled Oracle on HP hardware. Exadata 2 is essentially the same but with Sun x86 gear replacing the HP. Neither of these have the sort of numbers Oracle is promising here, and they've all but said it's Sparc.

A microkernel is just a performance hack. :)
