Or, you could have called the 800 number on the box and the company that produced the entertainment system would send you the missing or broken parts without any hassle or raising of voices.
An RFID card would be more likely to use a rolling-code instead of a challenge-response type of interaction. The challenge-response requires the RFID tag to both transmit and receive which is more expensive to produce. With a rolling-code, the RFID reader would activate the card, which would transmit its identifier and its current code, roll to the next code, and go back to sleep like the common keyless entry on cars. The card would require a small battery to save its state information, but the electronics would be much simpler. RFID is also slow and so can't transmit too much information without the user noticing the delay.
A book cipher and a random OTP are not "effectively equivalent." Your keyspace is greatly limited because the the next bit (or letter) in the book cipher is dependent on the previous bits (or letters).
Give me the CD and I'll be able to run through the different offsets and find an offset that gives me an English message. I will *know* that is the correct message because the rest of the offsets give me garbage.
Present something to me that has been encrypted with a OTP and I won't be able to determine which *random* stream of bits that produces an English result is the correct one. In fact, I will be able to "decrypt" the message to say whatever I want because the value of the OTP bits are independent of eachother.
A four character message would be difficult to decrypt (accurately) using Caesar cipher. That doesn't imply the Caesar cipher is a good cipher. There are just going to be quite a few words that are adjacent.
That is precisely how airbags are suppose to work. They operate in front end collisions at speeds over about 12 MPH. They work to spread you sudden change in velocity over a longer time period reducing the acceleration you experience. In a rear-end collision, your seat and head rest protect you. In side collisions, a side-impact airbag that erupts from the side of the seat or the headliner is suppose to protect you (in more modern vehicles).
slow death of the galaxies, billions of years from now
And this is where they find: "Oops, the universe ends in 12 years. We wouldn't have ever noticed the singularity in the array of interrelated equations without this simulation, but additional analysis and observations suggest it is accurate. The fundies and the doomsday psychics were pretty accurate with their estimates."
And so many Slashdot readers still won't have been laid.
I know it's too late and no one will read this, but...
I would like to point out that the level of engineering involved in the design of the shuttle is in a completely different class than any technology you have in your computer or in your car or that you've likely ever have had physical contact with. Cars and computers advance quickly because they are cheap and if they occasionally don't work no one really cares.
Everyone bringing up the age of the space shuttle sounds like morons. Whatever our next orbiter is going to be, the technology will be outdated. It has to be outdated by the time the thing is ready for flight because it has to be proven. You don't use the latest composite materials or computers in building something of this cost (dollar, life, and national pride) because you don't know how they respond to the excessive accelerations, vibrations, and high energy radiation involved.
This is assuming you're building a real vehicle and not a toy to win a prize. And actually, we probably will not see another feat of engineering like the current orbiter because the government doesn't give money to people who know what they're are doing like they use to and the private sector is too lazy and opportunistic to engineer it right.
This amounts to 106 thousand tons per U.S. McDonalds, compared to 1.58 million tons per Chinese McDonalds.
Bottom line: China sucks.
I let someone else calculate the emissions per Statue of Liberty for each country and emissions per Great Wall of China for each country.
Even worse is Novell GroupWise, which doesn't even quote properly.

And the next step is to move the servers out of temperature controlled area as that's the next biggest source of heat in most server rooms.

Also, McDonald's per country:
- United States: 13000
- China: 600
This amounts to 106 thousand tons per U.S. McDonalds, compared to 1.58 million tons per Chinese McDonalds.Bottom line: China sucks.

GroupWise is a damned lousy email client.
