You mean the number on your license plate depends on the temperature? Pretty nice idea. Indeed, you could have it just display the current temperature as number. That way, it would also be useful as standalone application. We just have to find a nice name for it... oh, I know, thermometer!:-)
Well, the problem is that the whole purpose of this network is to remove dangerous code. So even if the honeypot systems themselves could not be compromised, the system could compromise lots of other system by it's normal operation if a legitimate code sequence errneously gets classified as harmful.
Remember, natural autoimmune illnesses don't kill the immune system. They cause the immune system to go against other parts of the system (body) it is supposed to protect.
Pretty smart, if they can actually get it to detect even radically new virii.
That if is the big problem. After all, if such a system was employed, then the #1 goal of any virus writer would be to make the virus indetectable by the honeypots. Or alternatively, the virus could actually modify the honeypots to not report that virus, or maybe even use them to spread more efficiently.
Does this mean there will be more than just 1s and 0s when it comes to things?
Yes. But only as long as you don't look at it. Seriously.
Will there be more complex things going on?
Yes. It's called superposition and entanglement. In some sense, the qubit can be 0 and 1 at the same time (well, that's very much simplified, but you get the idea). Which means you can effectively do the same calculation on all possible inputs at once (this is called quantum parallelism). For example, if you have a function f which works on one bit, and want to know if it is constant (i.e. f(0) = f(1)), on a classical computer you have to evaluate f twice (once for 0 and once for 1). On a quantum computer you just need to evaluate it once (on a superposition of the 0 state and the 1 state, i.e. at such a state which is "both 0 and 1 at the same time").
No, the four possible states are: 1. The mechanism was triggered, and the cat is dead. 2. The mechanism was triggered, but the cat survived the poison. 3. The mechanism was not triggered, and the cat is alive. 4. The mechanism was not triggered, but the cat died anyway.
Another point where this could come from is quantum teleportation, where you have to transmit two classical bit to teleport one qubit. Of course that's because for teleporting one qubit, you measure a combined system of two qubits (one of which is the qubit you want to teleport, the other one is your part of the shared EPR pair), and measuring two qubits of course gives two classical bits.
I guess they produced an eigenstate of the atom number operator, therefore they should be quite certain.
What do qbit bytes taste like?
That of course depends on what they are made of:-) Now it's very likely that their qubits only contain the traditional flavours up and down, because particles with strange flavour tend not to be very stabile.
So is this cat dead or what?
I just looked: It is dead. However, now I have problems with PETA activists from Copenhagen who claim I killed the cat by looking...
If I am understanding this wrong, please correct me:).
You understand this wrong.
A qubit indeed can have one of a continuum of states. For example, if you think of the photon polarisazion, each linear polarization direction corresponds to a distingt state, and then there are the circular and elliptic polarized states as well. Indeed, you can map the states of a qubit onto a sphere (embedded in ordinary 3D space), which is called Bloch sphere. Every point of that sphere corresponds to a (pure) state of the qubit. (Note that the Bloch sphere is not the Hilbert space, but for single qubits, it's IMHO much easier to understand things in the Bloch sphere picture)
Now if you measure, you basically choose a direction on that spere, and you get just one of two results. e.g. if you think of the sphere as Earth's surface, and let's assume you have chosen the direction of the Earth's rotation axis for measurement, then if the state of the qubit (before measurement) is actually the North Pole, you get with certainty one result (which, for obvious reasons, I'll call "North"), and if the state is the South Pole, you get with certainty another result (which I'll now call "South"). However, even if the state is something else, your measurement will never give anything but "North" or "South". The probability to get "North" grows the closer the state is to the North Pole, and equivalently for the South Pole. If the state is at the equator, the probability of getting North or South is the same, i.e. the result of your measurement is completely unpredictable.
Now the funny thing is that after you measured North or South, for an ideal quantum measurement, the state actually is the corresponding Pole, no matter what it was before.
If you map the states described by the article with the Bloch sphere, and say you map the states 0 and 1 to the North and South pole, then the states you named `0 and `1 would be two antipodal states on the equator, say on the zero meridian and on the 180 degree meridian (unlike in the hilbert space, the directions now are not in 45 degrees, but actually orthogonal). That is, if the state is `0 or `1, then any measurement in the north-south direction will give completely unpredictable results. Of course if you choose the direction of the `0 and `1 states (I'll call that the equatorial direction from now on), then those states will create a predictable result, while the North and South pole states will get completely unpredictable results.
Now the nice thing for encryption is that if you don't know if the state was prepared in the North-South direction or the equatorial direction, there's no way for you to know if what you got for a measurement is a prepared state, or just random garbage. Moreover, since measuring in the wrong direction changes the original state (and therefore destroys the information which was originally in there), you'll be able to notice if someone tries to eavesdrop your connection.
Except that in this case, Wales did do anything about it: He removed the offending text from the history! To remain in the analogy, he removed the nazi slogans from the wall. Now, the Bellsouth case would be similar to if you knew the sprayer has used a certain taxi to get there and if you could get the name from the taxi owner you could get him. Now do you think the taxi owner should tell whom he drove (or even be allowed to, without a court order or at least the police asking him)? After all, it's too easy to just claim to have a reasonable interest in some private information. That's why there have to be courts in betwen: If you can get a court order, then at least a judge has double-checked your claim.
We're not all typing obscure commands in consoles all day, you know:)
Indeed, I'm usually typing obscure commands sitting on a chair in front of the monitor and keyboard. I would hate it to be locked into a console when typing obscure commands.
Ah, and of course I'm also not typing obscure commands all day. After all, I need some time to read Slashdot!
Now, having said that, the Slashdot interface clearly leaves something to desire, even when using Lynx. Why is there no true modular command line interface? I would think of something along the lines of

And why is a shell builtin not a command? For me, a command is something which I can type in a shell. It may execute a shell builtin, a shell function, an alias, or an executable found in the path, but in any case it's a command.
See e.g. the bash man page:
Simple Commands
A simple command is a sequence of optional variable assignments fol-
lowed by blank-separated words and redirections, and terminated by a
control operator. The first word specifies the command to be executed,
and is passed as argument zero. The remaining words are passed as
arguments to the invoked command.
See, no mention that a command has to correspond to an executable. It also has a section named "SHELL BUILTIN COMMANDS".
The fact that you cannot use sudo to issue a cd command is completely unrelated to that nomenclature (as is the fact that a csh may not be able to execute a bash builtin command). Note that even if sudo successfully executed the cd command (say, by executing it in a root subshell), the intended effect will not happen (because the directory change would only happen in the subshell - which immediatly terminates afterwards -, and the original shell's current directory will not be affected).
So before being pedantic, better first check you are right.
