Richard Stallman is giving his "Copyright and Community in the age of computer networks" lecture at Johns Hopkins tomorrow morning. For anyone who's heard it already: worth taking an early lunch to go hear? How long does it run?
I don't see how this bandwidth is a problem for secure key exchange.
Isn't the point of this to make it practical to utilize high bandwidth yet unsecured connections to send heavily encrypted data? Even when changing the key very frequently, the secure quantum channel should be more than fast enough.
It's just like satellite TV encryption. The data stream can be received with zero chance of detection anywhere within the satellite's footprint: even less secure than sending data over the internet. By having a seperate secure* key distribution stream, they can get away with this without massive piracy. In this case, this "stream" is the physical transfer of smart cards with keys stored on them.
* The problem is, it's not secure. Since the physical distribution of keys via smart card is so slow, the video decryption keys are sent encrypted over the high bandwidth yet unsecured satellite connection along with the video stream. The card uses its key to decrypt the video key, which is then sent back to the satellite receiver to decrypt the video stream. Since the receiver is ultimately less tamper-resistant than the smart card, and it could be possible to extract a video key from its RAM while running, this allows the video key to be changed every few seconds, making distribution of current keys to others useless. While this sounds good, the cards are not as tamper-proof as they'd like to be, and the expense of constantly swapping all customers' cards to new ones with fixes creates a legacy loophole. Combine this with an intrinsic inability to keep hackers from physically accessing all needed decryption hardware and no means to detect their hacks remotely, and it makes this method of key distribution very insecure against determined individuals. With good quantum connections, all these problems are avoided.
Blur, destroy? What's the difference anymore? We're getting to the point where for any given place on earth, more people are likely to have seen it online rather than in person. After that line's crossed, what's really real?
Sorry. Shouldn't listen to the RiffTrax for The Matrix while Slashdotting.
While' you're allowed to have it in your private use balcony, not one inch of the dish or your mounting hardware can stick out past the railing - that's no longer a private area.
Comeon - this is Slashdot. Is it too much to ask for this audience, one of higher-than-average intellect, to recognize that this "organic" food label is completely retarded? Really, why put up with this hijacking of a scientific term? No one I know is eating primarily inorganic food. And don't even let me NEAR the next guy to call cocaine a "narcotic"...

"What good is [a] smartphone if it can't be used when a subscriber is roaming across the country or even across the county?"
It's good for someone without $600+ a year to spend on mobile data. My Droid is quite happy with the phone unactivated and running off WiFi.

Why not just sink some turbines in the larger rivers near the turnpike and get the juice from there?
Off-topic, but...

That little error saved me from having to read a bunch of replies.

Wait a sec...
or is it simply going to breed discontent among under-qualified teachers?
Fixed it.
Aren't HID cards passive? Last I checked, they just reported a serial number.
So what is this "hack"? Recording and replaying the serial is nothing new.

Or will it mean film studios can stop movies from being copied when traveling on the internet?
No. Not at all.
Quantum "encryption" foils interception of a data stream. That has nothing to do with copying a file and resending it once it reaches its destination.
Except when Microsoft removes the ability for their OS to send out packets of any data you desire, as they've already done.

Mr. Clean and Nancy Kerrigan, obviously.
I put trying to modify world geography to make a buck pretty high on my "what counts as evil" scale. That's Bond-villian level there.
See an insecurity in their systems? They'll sue you to shut you up about it.

The full DVD of the first four episodes was ALL OVER Usenet on the 7th.
Thousands of people DLed that, and one guy encoded it for submission to YouTube.
No insider job here.
Forget clamping the dish ONTO the railing.

Ah right - but isn't that group for broadcast rips - I've seen plenty of 1080i movies up there, but whatabout 1080p?
alt.binaries.hddvd?
Holidays? Absolutely.
When you have money to burn, then you can burn it on Holy Days. Worry about food and rent now.
Somebody doesn't read alt.binaries.dvd too often...

When I was a child I always thought how nice it would be to visit England.
Now it just... I'm just really dissapointed is all.
Where did I get such a silly notion that public surveillance is 100% wrong, regardless of benefit?
The function of capacitors that you unhappily discovered is something like a temporary battery
And where can I find these other kind of permanent batteries? I hate having to keep recharging mine.
