It's called "Peek-A-Booty", created by the Cult of the Dead Cow. A fine bit of hacktivism inspired, if i'm not mistaken, by just this sort of behavior.
How long before we'll be forced to use it ourselves, i wonder?
Right, that's what i'm talking about. I wasn't commenting on any religion as a whole, merely the relegious views being espoused by the person i was replying to.
Anyhow, yeah, read your post, sounds pretty sensible to me.
if someone wants to die rather than receive medical aid, then..well, that's their perogative.
Keep in mind, though, those ancient laws were to -protect- their adherants, since suitable technology for safely perserving the meats had not been invented. Basic memetics. Can't pass on the ideas if all your followers are dead. If you trace back the relegious percicution of homosexuality, you find its the same sort of thing, tight reproductive rules had to be formed to keep the dwindling population alive in the face of persecution.
The ultimate irony is that those rules now cause the descendents of those same people to persecute others.
But I digress. If the codes of ethics can't adapt to future circumstances, the memeplex dies as surely as a maladapted organism dies in the environment. Human innovation is accellerating beyond the knee of the exponential curve, its going to be a rough transition, and those of us who know how to bend rather than break will be the ones left.
I'd gladly cover the lower fifth of my TV screen to get rid of commercials (that is, if i watched television at all anymore). If only it were that easy!
I'm more in favor of simply allowing the current, vacuous paradigm of "television" to collapse. The most informative news broadcast on contemporary television is "The Daily Show". Just let it go to hell, and then watch what rises up in its place. It can't get much worse.
I don't really see what the big deal is anyway...television holds a statistically huge captive audience of people who watch, on average, several hours (6? 7? 8?) of television per day. You can't walk down the streets of a suburban community without noticing the gentle flicker of the electronic babysitter lulling the herd to sleep at night. Electronic means of skipping commercials are neat, but the majority don't care. There's no difference in informational content and creativity between commercials and actual television programming, it's just another way for the masses to tune out.
So just let the bottom fall out. Watch the promise of technological circumvention of advertizing create conditioned responses from the industry before its effects are even manifest in large numbers. Let it react it's way into oblivion.
It's an organism now. It's not a group of CEOs or programming directors, or, god forbid -ARTISTS-, its a blind powerful organism that commands the attention of billions of people, and the precise nature of funding or advertising is barely relevant to the conditioned demand and dependancy that you feel humming in your streets and in your living rooms. It won't die without a fight, and most people depend on it to survive.
the difference between something being "legal" and something being "legal, but pisses off a major corporation" is a contrast becoming starkly clear lately.
I'm currently working at a RadioShack, where we keep a stack of these babies right by the Point-of-Sale as an impulse buy. At 50 bucks a pop, it seems like a big impulse buy, but we sell out of them pretty fast. Apperantly, this thing will respond to any machine-generated "wardialing" of the type typically used by telemarketers with those three tones you always hear when you dial a number that's "out of service" (boooo baaaa beeee!!).
The downside of this is that it dosent just kick in with telemarketers, but will activate in response to any call that uses that technology to mass-call people. Hopefully, insurance and banking representatives will continue to dial the old-fashioned way.
I find it gratifying that an earlier comment of mine about quantum entanglement was rudely put down as "impossible outside of science fiction and dilbert cartoons" is now receiving some front-page lovin'
I wouldn't write off Yog Shothoth just yet. If he's out, he's hungry and in need of souls. You have to wonder...breaking the pentagon AND causing a large number of deaths, almost simultaniously. I would look out for another state-sponsored mass-murder (probably by us), if Yog Shothoth has broken free from the Pentagram, he's very, very hungry.
I wonder if anyone ran to the ruins and tried to draw a chalk line from one side of the break to the other. I would, if i were nearby.
Could the government really be so uninformed as to institute countermeasures that not only take away our civil liberties, but at the same time are completely useless?
The cynical answer is "yes, of course they are".
...but sometimes I wonder. You and I both realize that these supposed "countermeasures" are completely meaningless in terms of terrorism, because we're Informed. The general populous is Uninformed.
Let's assume for the moment that the government is Informed. The certainly have the resources, and they have people working for them that know "what's up".
The simplest explanation is that government opprotunists are simply using this as an excuse to take away our civil liberties, so they can more effectively control us.
And to think they could be doing something productive with our tax dollars.
Im sure that somewhere, in the dark recesses of a government vault, there is a secret plan that outlines staging a terrorist attack on a US landmark, so federal officials can install the carnivore system unilaterally on American ISPs without complaint from the technologically knowlegeable.
I don't know how widely used this "toy" is, but my 11 year-old sister got a LOT of use out of her mindstorms kit. It combined simple robotics with an introduction to simple computer programming, and it wasn't long before i found myself on the lookout for motion-activated catapults whenever I had to go near her room. I found the experience rather stressful and unnerving, but she definitely learned a lot, and gained an interest in computer science as well.
Rather than invent a new standard of unique identification, why not use the existing social security numbers? I mean, it's a forgone conclusion that today's young adults are never going to see that money anyway, so why not put the numbering system to good use, instead of inventing a new numbering convention? The social security number has already been accepted as a legal form of identification.
From there, the challenge would be to reverse-engineer the existing system to make it impossible to fraudulently acquire someone's resources using their social security number, but surely this would be easier than inventing a new identification convention, right?
i'm afraid i dont know enough about diamagnetism to say for sure, but it's hard for me to accept that a magnetic force would effect every molecule the same way. Even the -slightest- difference in force at 10,000Gs would merely tear the passenger to shreds instead of flattening them like a pancake.
Even the inertial dampners from star-trek weren't perfect.
I think the path of least resistance in this case would be to take the approach taken in Event Horizon for rapid acceleration travel. The sleep pods the characters utilized in the movies not only cryogenically preserved them (which is out of the scope of this conversation), but it served to cusion them from the high G-forces by surrounding them with some sort of viscous liquid. Now, im not saying we fill the scramjet with peanutbutter and just sploosh the rider inside...
Man..I really feel like I missed out. Oh, the mayhem i could have caused with wireless networking, if i were allowed to bring a lappy to all of my classes with me. Diablo during classes (Q3A or counterstrike if it had one of those snazzy mobile GF2's in them), sending provocative messages over the network, completing my homework minutes after it's assigned and selling the answers with paypal over the network..oh, what a glorious time it must be to be a 7th grader.

When a publicly funded institution or service provides you with "free" (forgetting about taxes for the moment) internet service (email in this case), you can expect it to be restricted and/or monitored. The government already does enough unlawful invasion of privacy, i certainly don't want them administering my email account.
Hey, if this free email adress seriously hampered other businesses that sold this service (by giving it away free), would it be seen as anti-competative? It would be amusing to see the government's anti-monopoly rhetoric turned against them.
Ostensibly, once the weakness was discovered by the "sanctioned hacker", the weakness would be corrected, or, if that prooved impossible, the idea would be scrapped altogether.
Even still, i think it would be a mistake to ask a bunch of high school skript kiddies to perform a task best left to professional security auditors (ie: Mudge from @Stake, formerly from L0pht).
...But that's our gov. for ya. There's this steriotype of teenage kids who apperantly have such a high population density of "hackers", that you can vaguely request that an entire state full of them audit this system and expect professional results. The combined variables of
A) qualified Hacker exists in target range and age group (which is reasonable to assume might be true)
and
B) said person decides to attempt intrusion
and
C) said person succedes in intrusion
Seem rather unnessisary when you can pay a professional team of security auditors to "get the job done right".
do a web search on "quantum communication". Granted, most of the stuff is hypothesis and conjecture, but a few of the pages i came across mentioned actual sucessful tests. but if you look at the replies a couple Parents up, i responded to someone else's posts with some interesting tidbits. Put them in your pipe, ignite, and inhale deeply. No, no one's made a communication device that utilizes this concept, but quantum teleportation has been observed.
Fortunately, for all the masses of people who like to say something will never work, because it reinforces their view of reality, there are a few who persue their goals anyway. If everyone had been content that the microprocessor, rocketship, telephone, relational database, lazer beam, nuclear reactor et al were pipe dreams, we wouldn't have them (of course, a luddite would respond that we're better off without such things, but luddites shouldn't be using computers in the first place).
If current research on cold fusion and the room-temperature superconductor suddenly vanished, we would be missing out on an advancement that would radically improve the quality of human life, as we would if everyone just threw up their hands and said "screw quantum mechanics, this shit's just too hard!".
Saying that something would or would not work based on the math involved is a mistake that, thankfully, few theoretical scientists get too tripped up over. Many of the equasions that we use to describe physical reality have been "dumbed down" by popular scholars who "didn't know what all those fiddly extra variables were for", and the imminant marrige of the theories of gravity and quantum physics may bring about a drastic revision in how we describe what goes on around us.
At one time, rocket ships, wireless communication, lazer beams, and complex computer systems also existed merely in the realm of the imaginary. It is from this creative foundry that some great advancements emerge.
I tried to track down the report I read originally about a specific test proving that this theory works, but I only found a referance to it, it's the last "snippet" in the following.
Some snippets about the current state of quantum communication:
>>Bennett, Brassard, Crépeau, Jozsa, Peres and Wootters have now shown how an unknown quantum state can be "teleported" from one place to another (Phys. Rev. Lett. (1993) 70
1895). As in the previous example, Alice and Bob are each given one particle of the entangled EPR pair (see (b) in the figure). Then Alice brings together her particle and the particle in
an unknown state, and performs jointly on those two particles a special measurement using the quantum gate M. This measurement has four possible outcomes - it is, in fact, the same
measurement that is performed at the end of the two-bit communication process. Alice then communicates the result to Bob, by any ordinary channel, such as a telephone or radio
transmitter, According to this result, Bob, who has the other member of the EPR pair, performs one of four operations on his particle (the same four operations that were used in the
communication scheme) using the quantum gate U. The effect is to leave Bob's particle in exactly the same state that Alice's particle was originally in.
So far neither of these miracles is yet practical. Quantum gates such as U can be built, but the operation performed by the gate M, sometimes called a "Bell measurement", is beyond
present technology. Harald Weinfirter and Anton Zeilinger from the University of lnnsbruck in Austria have designed optical experiments, using so-called "parametric down-conversion
and a simple photodetection scheme, which would allow communication with more than one bit of information per physical bit. They are developing techniques that might allow quantum
teleportation too. But the theoretical results, whether they are practicable or not, are already of considerable importance, because they force us to fundamentally revise our concept of
information in physics.>Entanglement Generation
The generation of entangled photon pairs is routinely done in the laboratory using parametric down conversion. However, many of the applications contemplated involve the use of single
photon pairs upon demand.
1.A photon "function generator" is desired that would generate a single photon upon demand with near 100% efficiency. A more general capability would be the ability to generate a
deterministic number of photons upon demand. Single photon rates of 1-100 MHz are desirable.
2.Strongly nonlinear chi-3 media are needed that would produce nonlinear optical effects at the single photon level. This would lead to an efficient two photon nonlinear optical
converter.
3.The clear requirement for practical quantum teleportation will be to demonstrate completely deterministic generation of entangled photon pairs upon demand. The development of
multiphoton (entangled 3, 4, 5 etc. photons) sources will be needed for error correction and repeater systems. High count rates (>1MHz) demonstrated at fiber optical wavelengths
will be needed.
Photon Transmission and Detection
Generation of entanglement is but the first step in quantum communication. Efficient transmission and detection of the photons will preferably be accomplished through improvements in
existing technologies, but the need for quantum error correction and quantum repeaters was also mentioned.
1.As important as the requirement to generate photons on demand with high efficiency is the need to detect them with equal or superior efficiency. High efficiency, low noise, single
photon detectors (>70-80%) operating at the telecommunications wavelengths (0.8, 1.3, or 1.55 microns) are required. Dark counts less than 100 Hz and data rates of 10 MHz-1
GHz are desirable. Quantum nondemolition may be exploited to develop a new type of high efficiency detector.
2.Low loss transmission links over 100 km are necessary. For fiber optical communication, it is desirable to have fiber attenuation below 0.001 dB/km. For free space line of sight
communication or quantum key distribution, demonstration of ground-to-satellite links will require advances in adaptive optical technology.
3.Ultimately, existing telecommunications equipment must be used for any practical quantum communication network to be implemented. It will be critical to demonstrate the
feasibility of transmitting quantum information into, through, and out of commercial telecommunication links.
4.Demonstrate entanglement purification, then error corrected transmission of quantum states. For superdense coding applications to become a reality, it must be demonstrated that
robust photon pairs can be reliably transmitted and received. The objective will be to demonstrate 2 bits of information transferred per photon.>Recently, a close connection was established between nonlocality, Bell experiments, quantum communication, and quantum cryptography, on the one side,
and quantum logic gates, quantum computing, and quantum logic, on the other. [C.H. Bennett et al., Phys. Rev. Lett. 76, 722 (1996)] All of them, Bell
experiments, quantum communication/cryptographic schemes, and quantum computers use entangled systems as their inputs and the detection efficiences
of the latter were so far very low (under 10 experiments carried out so far relied only on (nanoseconds) coincidental detections and that made them
inconclusive in principle. [E. Santos, Phys. Rev. Lett. 66, 1388 (1995); Phys. Lett. A 212, 10 (1996)]. Recently we discovered a new kind of
entanglement [M. Pavicic and J. Summhammer, Phys. Rev. Lett. 73, 3191 (1994)] and a new preselective scheme of entangling independent systems [M.
Pavicic, J. Opt. Soc. Am. B 12, 821 (1995)] which should enable over 70 main hypothesis of the proposed project is that preselection of entangled photon
pairs can be used for designing quantum logic gates for quantum computers, for obtaining user-ready input pairs in quantum cryptography and quantum
communication, as well as for a long-wanted loophole-free Bell experiment, on the one hand, and that the algebraic representation of quantum logic (new
desarguesian orthomodular lattices) can provide necessary algorithms for quantum computers, on the other. The aim of the project is to carry out all the
elements from the hypothesis. Our basic methods will be our theory of the spin-correlated interferometry. [M. Pavicic, Physical Review A, 50, 3486
(1994)] and our new representation of quantum logic [M. Pavicic, Int. J. Theor. Phys. 32, 1481 (1993)]. First feasible loophole-free Bell experiment and a
feasible interaction-free experiment with over 95 so far) are expected as first testable results. An objective indicator of the importance and influence of a
branch is the number of papers in the leading journals, e.g., Phys. Rev. Lett., Phys. Rev. A, J. Opt. Soc. Am. B, and App. Phys. B. Only Phys. Rev. Lett.
with the highest impact factor, 7.2 of all physical journals published more than 20 papers in the branches of quantum computers, cryptography, and
communication (Bell experiments, quantum interferometry, etc.). On the other hand, we published in all the above journals recently. Therefore, the
proposal may be ranked as important. >I have already remarked that multiparticle quantum systems are described in terms of tensor products on Hilbert space , and that this implies existence of non-local interactions between
components of a quantum system. In principle the whole universe is entangled and you cannot take a chunk of it and isolate it from the rest. Even particles that are on two opposite sides
of the universe are connected by entanglement. This interaction is not mediated by any conventional field known to physics such as electromagnetism or gravity. It is instantaneous and in
clear violation of special relativity. The latter can be restored for the so called ``expectation values'', i.e., measured quantities, but the anti-relativistic correlations are still there. Bohm
[12] demonstrates that these non-local interactions can be described in terms of a very special anti-relativistic quantum information field that does not diminish with distance and that
binds together the whole universe. This field is not physically measurable though and the only way in which it manifests itself is through the non-local correlations. So it is, at least at this
stage, a matter of religion whether you want to believe in it or not. But the idea is interesting and derivable entirely from the Schrödinger equation .
Anyhow, whether you want to describe the non-local correlations in terms of Bohm's field or magic, they are there. Their existence was demonstrated experimentally by Aspect, Dalibard
and Roger in 1982 [1] , and predicted by Bell in 1964 [5] . But they manifest themselves also in superconductivity, superfluidity, and even in the Bohm-Aharonov effect . The first two
are macroscopic phenomena, and in the Aspect, Dalibard and Roger experiment, the existence of non-local correlations is demonstrated over a distance of . More recently
non-local correlations were demonstrated over a distance of some .
Quantum teleportation uses this non-local interaction, combined with a classical information channel (e.g., telephone wires) in order to transfer a quantum state, intact, from one location to
another one. How exactly this is done will be explained in Chapter 5.
So, there you have it. Can we communicate instantaniously now? well, no, we can't. That dosen't mean that we'll "never" be able to do it. People all over the world are doing experiments suggesting (and sometimes proving) that this could work.
You say that FTL communication will never be possible, but it has already been observed, we just have to utilize it.
Even in this case, the light is only moving at the speed of light, the information dosen't travel any faster.
The concept of molecular bifrucation communication is hardly useless. The basic concept is that when certain sub-atomic particles, when split off of their original Atom, exhibit an amazing property: when you change the spin of one, the spin of the other reverses -instantaniously-, faster than light. That is to say, not only was the time between the two changes in spin -unobservable-, it was -definately- longer than the amount of time it took to project a beam of light from one to the other.
Instantanious communication is ultimately useless?

present technology. Harald Weinfirter and Anton Zeilinger from the University of lnnsbruck in Austria have designed optical experiments, using so-called "parametric down-conversion
and a simple photodetection scheme, which would allow communication with more than one bit of information per physical bit. They are developing techniques that might allow quantum
teleportation too. But the theoretical results, whether they are practicable or not, are already of considerable importance, because they force us to fundamentally revise our concept of
information in physics.>Entanglement Generation
The generation of entangled photon pairs is routinely done in the laboratory using parametric down conversion. However, many of the applications contemplated involve the use of single
photon pairs upon demand.
1.A photon "function generator" is desired that would generate a single photon upon demand with near 100% efficiency. A more general capability would be the ability to generate a
deterministic number of photons upon demand. Single photon rates of 1-100 MHz are desirable.
2.Strongly nonlinear chi-3 media are needed that would produce nonlinear optical effects at the single photon level. This would lead to an efficient two photon nonlinear optical
converter.
3.The clear requirement for practical quantum teleportation will be to demonstrate completely deterministic generation of entangled photon pairs upon demand. The development of
multiphoton (entangled 3, 4, 5 etc. photons) sources will be needed for error correction and repeater systems. High count rates (>1MHz) demonstrated at fiber optical wavelengths
will be needed.
Photon Transmission and Detection
Generation of entanglement is but the first step in quantum communication. Efficient transmission and detection of the photons will preferably be accomplished through improvements in
existing technologies, but the need for quantum error correction and quantum repeaters was also mentioned.
1.As important as the requirement to generate photons on demand with high efficiency is the need to detect them with equal or superior efficiency. High efficiency, low noise, single
photon detectors (>70-80%) operating at the telecommunications wavelengths (0.8, 1.3, or 1.55 microns) are required. Dark counts less than 100 Hz and data rates of 10 MHz-1
GHz are desirable. Quantum nondemolition may be exploited to develop a new type of high efficiency detector.
2.Low loss transmission links over 100 km are necessary. For fiber optical communication, it is desirable to have fiber attenuation below 0.001 dB/km. For free space line of sight
communication or quantum key distribution, demonstration of ground-to-satellite links will require advances in adaptive optical technology.
3.Ultimately, existing telecommunications equipment must be used for any practical quantum communication network to be implemented. It will be critical to demonstrate the
feasibility of transmitting quantum information into, through, and out of commercial telecommunication links.
4.Demonstrate entanglement purification, then error corrected transmission of quantum states. For superdense coding applications to become a reality, it must be demonstrated that
robust photon pairs can be reliably transmitted and received. The objective will be to demonstrate 2 bits of information transferred per photon.>Recently, a close connection was established between nonlocality, Bell experiments, quantum communication, and quantum cryptography, on the one side,
and quantum logic gates, quantum computing, and quantum logic, on the other. [C.H. Bennett et al., Phys. Rev. Lett. 76, 722 (1996)] All of them, Bell
experiments, quantum communication/cryptographic schemes, and quantum computers use entangled systems as their inputs and the detection efficiences
of the latter were so far very low (under 10 experiments carried out so far relied only on (nanoseconds) coincidental detections and that made them
inconclusive in principle. [E. Santos, Phys. Rev. Lett. 66, 1388 (1995); Phys. Lett. A 212, 10 (1996)]. Recently we discovered a new kind of
entanglement [M. Pavicic and J. Summhammer, Phys. Rev. Lett. 73, 3191 (1994)] and a new preselective scheme of entangling independent systems [M.
Pavicic, J. Opt. Soc. Am. B 12, 821 (1995)] which should enable over 70 main hypothesis of the proposed project is that preselection of entangled photon
pairs can be used for designing quantum logic gates for quantum computers, for obtaining user-ready input pairs in quantum cryptography and quantum
communication, as well as for a long-wanted loophole-free Bell experiment, on the one hand, and that the algebraic representation of quantum logic (new
desarguesian orthomodular lattices) can provide necessary algorithms for quantum computers, on the other. The aim of the project is to carry out all the
elements from the hypothesis. Our basic methods will be our theory of the spin-correlated interferometry. [M. Pavicic, Physical Review A, 50, 3486
(1994)] and our new representation of quantum logic [M. Pavicic, Int. J. Theor. Phys. 32, 1481 (1993)]. First feasible loophole-free Bell experiment and a
feasible interaction-free experiment with over 95 so far) are expected as first testable results. An objective indicator of the importance and influence of a
branch is the number of papers in the leading journals, e.g., Phys. Rev. Lett., Phys. Rev. A, J. Opt. Soc. Am. B, and App. Phys. B. Only Phys. Rev. Lett.
with the highest impact factor, 7.2 of all physical journals published more than 20 papers in the branches of quantum computers, cryptography, and
communication (Bell experiments, quantum interferometry, etc.). On the other hand, we published in all the above journals recently. Therefore, the
proposal may be ranked as important. >I have already remarked that multiparticle quantum systems are described in terms of tensor products on Hilbert space , and that this implies existence of non-local interactions between
components of a quantum system. In principle the whole universe is entangled and you cannot take a chunk of it and isolate it from the rest. Even particles that are on two opposite sides
of the universe are connected by entanglement. This interaction is not mediated by any conventional field known to physics such as electromagnetism or gravity. It is instantaneous and in
clear violation of special relativity. The latter can be restored for the so called ``expectation values'', i.e., measured quantities, but the anti-relativistic correlations are still there. Bohm
[12] demonstrates that these non-local interactions can be described in terms of a very special anti-relativistic quantum information field that does not diminish with distance and that
binds together the whole universe. This field is not physically measurable though and the only way in which it manifests itself is through the non-local correlations. So it is, at least at this
stage, a matter of religion whether you want to believe in it or not. But the idea is interesting and derivable entirely from the Schrödinger equation .
Anyhow, whether you want to describe the non-local correlations in terms of Bohm's field or magic, they are there. Their existence was demonstrated experimentally by Aspect, Dalibard
and Roger in 1982 [1] , and predicted by Bell in 1964 [5] . But they manifest themselves also in superconductivity, superfluidity, and even in the Bohm-Aharonov effect . The first two
are macroscopic phenomena, and in the Aspect, Dalibard and Roger experiment, the existence of non-local correlations is demonstrated over a distance of . More recently
non-local correlations were demonstrated over a distance of some .
Quantum teleportation uses this non-local interaction, combined with a classical information channel (e.g., telephone wires) in order to transfer a quantum state, intact, from one location to
another one. How exactly this is done will be explained in Chapter 5.
So, there you have it. Can we communicate instantaniously now? well, no, we can't. That dosen't mean that we'll "never" be able to do it. People all over the world are doing experiments suggesting (and sometimes proving) that this could work.
You say that FTL communication will never be possible, but it has already been observed, we just have to utilize it.
Even in this case, the light is only moving at the speed of light, the information dosen't travel any faster.
The concept of molecular bifrucation communication is hardly useless. The basic concept is that when certain sub-atomic particles, when split off of their original Atom, exhibit an amazing property: when you change the spin of one, the spin of the other reverses -instantaniously-, faster than light. That is to say, not only was the time between the two changes in spin -unobservable-, it was -definately- longer than the amount of time it took to project a beam of light from one to the other.
Instantanious communication is ultimately useless?
Hardly.
