How does the program track mouse movements
? Does it use a compass (with forward being "north") and assign a number depending the degrees (1-360)? How does it use mic noise? There is no such thing as a true "random number generator". The only exception is in quantum mechanics, which is impossible to use at the moment. There is no perfect encryption, and there will always be flaws to exploit...hey, we're only human.

Well, whoever did it would have to be really smart, there are ways to accidentaly 'ruin' Public Key Encryption. Also, they would only have to seize the computer that recieved the message, the public key would be useless for decryption...even then, they only have to get the private key itself (not the whole machine), they'd find a way. How was the private key generated, for instance? Was it a program that can be reverse engineered, so when given a public key, it will generate a private key? Just something to think about.
There's a problem with that. The FBI isn't listening to every phone conversation in the US for key words, and they treat VoIP the same as regular phone conversations. So before they "listened in" they would have to prove to a judge that they had a reason to suspect you were doing something violating federal law. So unless you were really a federal criminal, you're only wasting your bandwidth.

Sure, for a few conversations between buddies, encryption would baffle an individual. However, this is the US government-with tons of money to throw around...they'll find ways around encryption. Usama's satellite phone was "encrypted", but the NSA could crack it easily enough. If it becomes a great enough need, the government would find out how to decrypt it. They wouldn't brute force either. When the British found the Enigma machine, the US and British intelligence services reverse engineered it and then used it for the remainder of the war. Same thing would happen here: If the case was high-profile enough, the FBI would find the program used and reverse engineer it so they could thwart the encryption. I'm willing to bet that Nautlius (Blowfish) has already been cracked by the CIA/FBI/NSA, and that they have their own proprietary software for VoIP tapping. The only way to avoid it would be to design your own encryption software, and then make sure it doesn't fall into the US Military's/FBI's/NSA's/CIA's hands. Those agencies employ some of the best hackers/programmers in the field, and it would be near impossible to keep multiple VoIP conversations encrypted without changing software every conversation (and even then, you would have to have every conversation based on the understanding that those may be decrypted later.) This is because of the open structure of the internet.
No, the sky is blue on earth due to the exact conditions we have here. If our atmosphere was less dense, the sky would be darker (less diffused light). Our atmosphere is so dense and made up of the right stuff (nitrogen, oxygen, carbon dioxide) that our sky is actually violet. However, because our sun puts off more yellow and green light then any other colors, our eyes have adapted to seeing those colors better, and the sky appears to be "sky blue". As the atmosphere gets less dense, it shifts left on the EM scale (roygbiv), and gets darkers overall. As it gets more dense, it shifts left on the EM scale(that's why sunsets are red, the sunlight passes through more air at sunset and sunrise) It's actually very complex to determine what color a sky will be. It depends on these factors- Incoming light colors atmosphere make-up atmosphere density angle of incidence the eye of the observer
That's why Mars has a butterscotch sky- very low density atmosphere made up almost entirely of CO2
This story should be pulled, it is wrong in too many places, and is just a bunch of conspiracy mumbo-jumbo. The pictures are slightly modded for color, but that's because it's a collage
As evidenced, here, the Martian sky is more yellow/butterscotch (they used the Viking landers American flag to balance the colors properly,pictures are on the website). The Martian sky doesn't really get "overcasted" as there is no moisture in the air to create clouds! There is dust, yes, but the atmosphere is so thin, the sunlight can still go through it. Ares2003 has a few loose screws-My guess is that the digital image of the craft itself was taken later in the martian day, and modifying the color of the photo was the only way to make it look like it "fit in". Mars should not have "earth-like" colors. Any glance through a moderately-powerful telescope will show that the "red planet" is, in fact, red in color (iron oxide dust). Those more yellow pictures of Mars floating around are actually not real photographs, but generated images from the Mars Orbiter Laser Altimeter data.

I've had 2 AMD processors "melt" on me (not me personally, but on computers I built for people) over the past 3 years...the heatsinks just fell off when the owners moved the computers. The Athlon heatsink retention sucks, I might consider recommending Athlon 64s, but only if the problems (including heat) have been fixed. Since then, I'm Intel all the way, their processors may be a bit more expensive, but I only have to buy one!
Gamma radiation is not impeded, reflected, refracted, or altered in any way by Earth's magnetic field. Magnetic fields only affect charged particles, which gamma rays are not. (Do you have any idea what they are?)
Gamma Radiation doesn't reach the earth's surface! Why? Because it is block, refracted, and impeded by Earth's magnetic field! Any High School education should teach you this. What causes the Auroras? High energy EM waves that have been redirected to the poles. Other high-energy EM waves are absorbed! Geez, google it if you must
It would be incredibly difficult, as well as dangerous to bring it back, but it would be really, really cool, so maybe it's worth it.
As for when it should be decommisioned, it should happen when we have a replacement for it, it is a great research tool and we can't afford to lose it. Ground based telescopes are so limited. Besides, how else are we going to look back 8 billion years if we don't replace it right away? Something might happen;-)
The problem with comparing this to iTunes is that you're getting music out of it...not internet content, they are 2 very different things.
The other problem is if we move to a "cable" way of paying things we get "content networks" like...say...IGN
It doesn't fix the fact that most people don't want to pay for internet content in any way, shape or form. Case in point- IGN. Even though that was subscription based, it's complete "collapse" as it were was caused by moving to the pay model. Fileplanet is having the same types of troubles, as their "exclusive" downloads quickly become not so exclusive. People aren't ready to move beyond advertiser supported web content in droves. It's too early.
They extended the mission MULTIPLE times, and even landed it on an asteroid (yes, landed, very softly too) This European mission isn't even worth mentioning. They're going to map the moon, whop-de-freaking do. The only reason it's getting press is because of the ion engine, which if the press cared about the American space program they would have reported that NASA has already succesfully untilized ion engine technology in space for hundreds of days in a row. It was shut down after hundreds of days of use (and after it had completed its mission). Then they restarted the engine (unprecedented!) by 'shaking it up' with the gas maneuvering jets. You've misread your space history, jd.
We can't even get really, really expensive solar cells (like on SS Alpha) to get near 50% efficiency. Like cold fusion and anti-gravity, this has yet to be figured out. Slashdot has jumped on a hype for something that doesn't exist.

Deep Space 1 certainly did not fail (who in their right mind would send a multi-million dollar probe up without testing it first?!) Here's proof.

DS1 was one of the most successful missions that NASA ever had. If you doubt me, you can look at the site...Official DS1 site
