In a non-bonehead password scheme, user passwords are stored after running them through a one-way hash function. A quantity of random data can be added to the password before hashing, to prevent identical passwords from producing the same hash, thus revealing the fact that they are identical. This is called a salt, and can be left out in the open. To check a password, you put the entered password and the unprotected salt together, hash them, and check the value against that stored.
It's just a badly formed sentence, and is not terribly correct or incorrect. A much better sentence would have been "Neither Dell the person nor Dell the company is interested in acquiring Red Hat" Still pretty convoluted, mind you.
That's the thing. The ATM's don't read it. The ATM says, 'Hey, bucko. Encrypt this with your private key.' The card does so, the ATM decrypts it with the public key, and when the result is the same, you know it's the right card, without anybody except the card knowing its key.
I think the problem might lie in the difference between being self-taught and being taught by others. In my own experience, I have found that I become quite frustrated in trying to help people with computers, simply because just about everything I know was either learned from plain ol' messing around, or through some sort of document, without any sort of instructor. When I'm asked for help, I think "Why can't they just figure it out themselves, like I did?"
Physics, on the other hand, something which I'm also not too shabby at, I find quite easy to help people with, because it is something which I have had taught to me. I know how to talk to somebody who doesn't understand physics, because initially, I didn't understand physics, and had to be taught.

No it's not. The golden mean is (1+sqrt(5))/2. That page you linked even says so.

Does your teddy bear have ethernet cabling sticking out of severl appendages as well as a power supply? Then yes, they probably would.
uh, of course your change in kinetic energy is 0. You stay in the same place, chief.
The problem is making the zeppelin on a whole less dense than the atmostphere, which while easy-ish on Earth, would probably be really tricky on Mars.
