    How would you know when your OS has been modified (without your approval), replaced (without your approval) or worse yet modified in a way which you were not informed.

    Run an intrusion detection program from a physically remote computer. Such a program compares a snapshot of the system (stored on the remote computer) to the current system. A reinstallation will be detected and reported. In order to defeat this system, the intruder needs to physically compromise two machines at once. You can even set up intrusion detection from several remote mahines to guarantee that physical access isn't a risk. Problem solved.

    Frankly, I don't see how your "source modification and reinstallation" attack is a risk specific to open source systems. There are utilities that can accomplish the sort of things you're talking about without modification of source code, and if an attacker has physical access to a machine, they'll be able to get in regardless of what OS you're running.

    How the proteins produced by DNA manage to work together as catalysts to create the chemicals needed to form an organism is almost totally unknown, yet by definition it is a cellular automaton problem!

    How so? I see it as more of a systems control problem. The trouble with looking at the components of a cell as cellular automata is that implementations of CA require a set of simple rules to go from one state to the next. There are no simple rules for protein interactions, however. It's complicated chemistry and complicated mechanics in a geometrically intricate container. Sure, you could argue that it would be possible to simulate all the molecular structures and interactions de novo from quantum mechanical principles, but the computing power is simply out of reach, and will be for quite some time. Plus, what insight does such a simulation give you? I just don't see how cellular automata apply.

    We have not even begun to understand how cells use those instructions.

    My point above was that we, in fact, understand very well how the genetic instructions encoded in DNA are used by cells. The map from gene sequence to protein sequence is understood perfectly. The most pressing outstanding problems in cellular and systems biology are simply not genetic: they center, rather, on complex interactions between the various components of cells and the cellular environment. Answering the questions you cite will require a detailed understanding of these complex interactions.

    Then please tell me where the gene is that determines blue eyes versus brown ones.

    Three genes for eye pigment have been identified: EYCL1 codes for the green pigment. It is located on chromosome 19 (genome data bank accession ID GDB:119269). EYCL2 and EYCL3 are both brown pigment genes. EYCL2 is on chromosome 18 (GDB:4642815). EYCL3 is on chromosome 15 (GDB:4590306). There are also diffusional control genes, which determine the pattern of pigmentation. Blue eyes occur when the pigment genes are not present.

    I stand by my statement that the "genetic code" is well-understood. We know how DNA works, and we know how to interpret gene sequence to get protein primary sequence. It's going from protein primary sequence to protein function that's the hard part, as well as understanding the complex interactions between proteins, cell environment, and DNA transcriptional control.

    Not sure what you mean by that. The genetic code is understood perfectly well: we know exactly how bases map to codons map to amino acids, and we've known for over 40 years. The mechanisms of DNA replication and transcription are also understood to exsquisite detail, as is the mechanism of translation from mRNA to protein. Protein folding is poorly understood, as is the complex cellular feedback loop between protein content, cellular environment, and DNA transcriptional control. I don't see the immediate application of Wolfram's CA ideas to these problems.

    DNA is just oodles of four-state variables that represent some kind of program. It is exactly like the cellular automata he's been working with.

    I can see why DNA would remind you of the sort of CA that Wolfram is working with: it's 1D, linear, and can take on one of several states at each position. However, DNA is not a cellular automaton. With a true CA, the state of the system at iteration i is dependant on the state of the system at iteration i-1 (or earlier). You can describe it as a Markov chain, I think (please correct me if I'm wrong about that). On the other hand, if we consider an "iteration" of the DNA system to be a single round of DNA replication, then the state of the system at iteration i is identical to the state of the system at iteration i-1, with some noise thrown in. If, on the other hand, we consider an iteration to be a single generation of reproduction of the species, then the state at i is dependant on all sorts of things unrelated to i-1: mostly the choice of a mate, which is heavily determined by chance and environment.

    You have absolutely no idea what you're talking about.

    The catch is, what else resonates at around 2.45GHz? Well, DNA for one thing.

    Where did you get this idea? And which "resonance" are you talking about? In the case of water, the microwave frequency is resonant with a vibrational mode of the molecule; hence, putting water in a microwave over increases its temperature. Exciting a vibrational mode of DNA would also increase it's temperature, but you have to keep in mind that the mass of a DNA molecule is on the order of a million times greater than that of a water molecule, so you need a proportional increase in the power to get an equivilent increase in temperature. And that has nothing whatsoever to do with mutagenesis. Damage to the chemical structure of DNA requires ionizing radiation, which radio/microwave radiation certainly is not.

    As for being only a meager 1-2 watts? I played with a meager 2 watt water-cooled laser once. It was too bright to look at, even with filters.

    Apples and oranges, my friend. Apples and oranges. And I guarantee you that a bandpass filter at a frequency other than that of the laser beam would have made it perfectly tolerable to "look at", as none of the light would have passed through.

    Thank god your not a Constitutional lawyer. Maybe you should read it sometime. Having a standing army was the last thing The Framers of the Constitution wanted.

Only in times of war, are there supposed to be a standing army." Jelque, however, seems to think that he (she?) has some disagreement with ktakki on this point, indicating a lack of familiarity with the English language. Also, there's Jelque's piss-poor use of English (your vs. you're, "are there supposed to be", etc.)

Statistics on spontaneous remission of schizophrenia are hard to come by, mostly because of the large proportion of sufferers who are either chronically institutionallized or victims of suicide.

    (ii)

    from which the sounds and material can be perceived, reproduced, or otherwise communicated, either directly or with the aid of a machine or device.

    A ''digital musical recording'' does not include a material object -

    (i)

    in which the fixed sounds consist entirely of spoken word recordings, or

    (ii)

    in which one or more computer programs are fixed, except that a digital musical recording may contain statements or instructions constituting the fixed sounds and incidental material, and statements or instructions to be used directly or indirectly in order to bring about the perception, reproduction, or communication of the fixed sounds and incidental material.

    (C)

    For purposes of this paragraph -

    (i)

    a ''spoken word recording'' is a sound recording in which are fixed only a series of spoken words, except that the spoken words may be accompanied by incidental musical or other sounds, and

    (ii)

    the term ''incidental'' means related to and relatively minor by comparison.



    That's the entire definition; nothing about SCMS, and certainly nothing about copyability.

    So the issue here seems to be an argument that cd copy protection violates the Audio Home Recording Act of 1992. Find a breif summary of the law here, and the actual text of the law here.


    The main thrusts of the law are:

    -No copyright infringment suit can be brought against someone making home digital recordings.

    -Retailers have the right to sell copying equipment and media, so long as they contain serial copy protection.

    -The RIAA collects a royalty of 2% on copying equipment and 3% on media.


    That the RIAA might be violating this law by making copy-proof cds is not immediately apparent from a quick reading. In fact, the definitions of what is and is not a "digital musical recording" do not seem to hinge in any way on the "copyability" of the recording, and the only qualification for entitlement to payments is that an entity is making and distributing recordings so defined.


    The point that copy-proof cds violate the spirit of this law is a good one. I think that any argument that the letter of the law is violated is weak, however. Anyone who can determine otherwise would make me happy, though, since IANAL.


    As a final point, the fact that a congressman is looking into this might make violation of the letter of the law irrelevant since congress, of course, has the power to create new law.
