You can't effect the outcome of a random event. The article does a good job of explaining this in simple terms using the example of two quarters. Say one quarter is left in an unopened box on earth, and the other quarter is sent to mars to be flipped. The box on Earth can only be opened AFTER the martian flips his quarter on Mars or it voids the experiment. If the Martian quarter comes up heads, they will find the quarter in the box on earth heads up as well. The problem with using this phenomena for communication is that the Martian cannot effect the outcome of the coin toss..
You have to remember that at these extreme altitudes the temperature is around -80C, so the loss of helium is a lot less than it would be at sea level. As mentioned in a previous post perhaps you could gain some additional lift from a stirling cycle lessening the amount of helium required. A stirling engine would take advantage of the temperature differential between the sun warmed upper surface, and the cool underbelly of the craft.
A fleet of these craft surfing the jet stream could provide complete coverage even though no single craft kept station over any given spot on the ground. LEOS have to account for their relative motion above the earth, so it may not be a problem for a fleet of lighter than air craft.
There are rare meteorological events which cause strong 200+ knot outflow in the upper atmosphere in all directions. In this case of course it would be impossible to station keep with solar powered craft.
Quantum cryptography is the only encryption method that eliminates person in the middle attacks. Naturally there has been a lot of interest from the security industry. Photons are a good medium for communications since they don't give off much of an electronic or magnetic "wake" that could be detected.
Slashdot has covered the implications of increased speed in factoring and how that might effect the PGP key space in past articles. The only thing new that I found in the article was how superposition in quantum computing could speed database searching.
There are two r's in carnivore, thought maybe the "r" stood for something meaningfull like reconnaissance. Of course then I tried to do something with the 'a', aardvarks strictly speaking are carnivores, but I doubt the FBI has much use for them as they are strictly a warm climate critter:)
Sounds to me as though they would just like to limit dissemblers to legitimate use. As much as I don't like my "tools" being labeled as "weapons of mass destruction", I don't see any problem with us programmers keeping them low profile. I don't think that it would be very easy to regulate reverse engineering tools, since most of the people that use them are savvy enough to aquire them. I am guessing that this legislation is aimed at web sites that provide scripts, and "one click" solutions, the problem is that an overzealous enforcement could turn legitimate programmers into rum runners.
Shouldn't be too much of a problem as long as you stay upright with your head close to your center of gravity. I can see your point though, if you are crawling around on hands and knees. Maybe they attach a "this end up" marker on your forehead to track your point of perspective.
You would think they could use some kind of 3d nano tether system or something? Be interesting to see what kind of gravity independent clock they will use.
Superficial VS message. Obviously most/.ers are going to click on the left button. Now that we have "adjusted" the link count a little bit, maybe they will start aiming the news a little toward the slashdot crowd. These agencies just report it in a way that sparks interest, its a democracy.
It does allow you to code your own extensions. Try searching for wpmforms.zip, it contains all the programmers tools necessary to create windows extensions for Pegasus. Many of your correspondents are likely to have windows based machines. I have noticed that non technical people tend to value the convenience of only having to click a couple buttons to encrypt. Port your girl friends a copy of your favorite encryptor.
You probably wouldn't need any special G force resistant furniture for an elevator like this. Ion motors take a while to build up speed. Just plop down in a lazy boy and wait for the sound of the DING.
With other operating systems such as Apple or Windows you get a descrambler. It would be almost as easy to copy the output from a licensed Windows descrambler that comes with every DVD device, as it would be to copy the output from DeCSS. I think a case should include a clearer intent to distribute in order to prosecute.
Your secret key is not secured by your password, it is secured by a hash of your password. Several different passwords or passphrases may hash to the same value This leaves you open to what is known as a Birthday attack. If you look at the source code for whatever version of PGP you are using you will be able to tell what hash function is being used. In the case of all PGP versions that use the old V3 keys (that I could find) this is MD5. The MD5 algorithm is clearly described in RFC1321
these RFC's are definately worth the read if you are serious about security. I read an article a while ago where the police were trying to break someones password to get evidence for a trial. The article said that after a long time trying to crack it, they finally found the only password that would unlock the file was "a hole in one!". If the bad guys had hashed the password with MD5 the police would have been able to crack it much quicker. I don't have a problem with someone who has a proper warrant being able to crack my keys. What I do have a problem with, is some private dick being able to grap the keys off my harddrive, crack the keys with a PC and sell the unlocked contents to the highest bidder. Common sense precautions should prevent this from happening, but there are still a lot of badly installed PGP programs out there.
So the solution then is to go back and use the old V3 keys with versions 2.6.2 or 2.6.3? If people do, they need to remember to keep their keys off of their hard drive. The older dos versions of PGP used MD5 to protect the secret ring. I have heard security experts recommend switching to a stronger hash function at least SHA if not Tiger. PGP is the only commonly used encryption standard we have. As it is, very few people use it. It would be ashame if we scared people away from using it to the point where "----- BEGIN PGP" became an automatic CARNIVORE snak.
I just spent the last 20 minutes stomping on banner adds to help some poor guy afford server resources. It seems they wrote a really good NASM manual but can't afford the server resources to distribute it. I would have paid a few bucks for that manual.
I suppose it is sort a sort of filter by natural selection. An employer that would be bothered by the knowledge that they hired a person convicted of the kinds of things "Phiber Optic" was convicted of, would not be a good match for him or her anyways.
From reading the article it appears (and I only have this single media representation to judge by) that PO was a straight shooter who did not steal and was mostly interested in exploring and understanding.
Perhaps the biggest crime committed here was a failure to play the political games. During the 80's and early 90's as I remember the internet was more of a wild west where Academic turf was protected vigilante style. An unfortunate explorer might find themselves strung up for being on the wrong port at the wrong time.
If you are a high profile company and allready have the moths doing circles around your flame it shouldn't matter that much. On the other hand many companies see themselves as low profile and do not wish to attract attention to themselves. What really irks me is that many criminals have had their records closed by the court, I have seen common embezzlers that have been convicted of stealing hundreds of thousands easily slide past employment screening. At the same time I have seen computer pranksters denied employment because they were spotlighted by the media. As long as inflated "Hacker stories" are in vogue and considered worthy of reporting innocent parties will be injured.
It ain't are fault, it's those dang blunderbusses they make us use to hunt varmints. The kick back from those guns is enough to make anybodys teeth loose. You have to admire a steady hand though, whether aiming a gun or soldering a chip.
Well maybe they have calculated the next major asteroid impact and decided to play a practical joke. It would be like a message from Atlantis the lost and forgotten civilization or something.
Guess it would be the ultimate FIRST POST!

I imagine a chess program written for a quantum computer would always play black and you would never win.

Is Postgres the only DB that will run on Linux and does rollbacks? There must be others, I would imagine journaling is a must have for serious work.

I am really stupid tonight, but I couldn't seem to find what CArnivore stood for in any of the links, anyone care to share?

It was bound to happen, high profile individual takes on big money. The Roswell aliens have started removing him from the newspeak.

And how do you know that p and q are prime to begin with so you can use them?

"section A.141 unavailable due to generosity"
Now we take that same amount of space and fill it with interacting interacting particles/waves. How much do we gain from quantum superposition?
I suppose it is sort a sort of filter by natural selection. An employer that would be bothered by the knowledge that they hired a person convicted of the kinds of things "Phiber Optic" was convicted of, would not be a good match for him or her anyways.
