  1. Re:Why the byte is not an 8th SI base unit on Experts Suggest Replacing Definition of Kilogram · · Score: 1

    I agree that there should be an SI base unit of information, but I think it should be the bit, not the byte.

    Here is an example of a situation where millibits are meaningful:

    Take 80 characters of 8-bit ASCII text. Call this P(0).

    For each n from 1 to 999:
    Retrieve 640 bits from a high quality random source. Call this R(n). XOR each bit of R(n) with P(n-1) and call the result P(n). Securely destroy all copies of P(n-1).

    Having executed this process, you are left with the single value P(999) and the 999 values R(1)...R(999). For convenience, let's use a new naming scheme, Q, defined as follows: For 1..999, Q(n)=R(n), and for 1000, Q(1000)=P(999).

    To retrieve P(0), use an accumulator, A, which is a variable of 640 bits all initially set to zero. For all n descending from 1000 to 1, XOR each bit of A with Q(n) and store the result in A. At the end of this process, the contents of A will be equal to the original P(0).

    Because we can re-create P(0) using Q, the value of P(0) must be contained within Q. All elements of Q are required to retrieve P(0); if any single element of Q were to be lost, then P(0) would not be recoverable. No element of Q is more or less important than any other in the reconstruction of P(0).

    How many bits of information from P(0) are contained in any single element of Q? The answer, obviously, is 640 millibits, or 80 millibytes.

    The prefix "milli" is here used in the metric sense of 1000. I suppose it would also be possible to say that we had 625 mibibits. However, this presents a problem: With only the letters "mi" to indicate the prefix, how do we know if a mibibit is 1/1024 of a bit (related to "milli") or 1/1048576 of a bit (related to "micro")? Do we have to resort to milbibits and micbibits, or millibibits and microbibits?

    This message is 1934622720 micbibits in length.

    They are based off physical things, but not PARTICULAR physical things. If you define a second in terms of the oscillations of a cesium atom, then in principle anyone in any laboratory can create an accurate atomic clock, because in principle anyone can get ahold of a cesium atom.

    The kilogram, on the other hand, is defined in terms of the ONE AND ONLY official reference kilogram. You cannot independently verify the weight of a kilogram, unless you can get your hands on the official one, which is unlikely as a practical matter. On the other hand, if the definition were changed to be 10^3 times Avogadro's number times the atomic weight of hydrogen (for example), then anyone in any laboratory could in principle create a "correct" kilogram.

    The key word is "particular." Of course it's impossible to define a measurement without referring to categories of objects in the world. The goal is to avoid referring to SPECIFIC objects in the world.

    Why does nobody understand the social security trust fund?

    The increase in payments caused by the retirement of the Baby Boom generation was predicted in the 70s. The Reagan administration got a payroll tax increase enacted, to build up the trust fund and make sure that we could cover the costs.

    We have been paying this tax since 1983. We have collectively paid $1.7 TRILLION dollars in extra taxes, to build up the system so that the Boomers can retire. Mostly, these taxes have been paid by the Boomers themselves, during their peak wage-earning years.

    Social Security was carefully designed so that nobody leeches off anyone but themselves. You pay in for your entire working life, then you draw during your retirement.

    Reducing benefits (which is what "privatization" or "personalization" really means) is nothing more or less than stealing from the $1.7 TRILLION that we have ALREADY PAID in taxes.

    Oh come on, you just aren't trying hard enough.

    The Galactica is not a naval ship, it is a spacecraft. So we would expect it to be operated by the Air Force. As a result, the officers all have Air Force ranks. Starbuck is an O-2 (Lieutenant); we know she isn't an O-1 because she took over flight operations when Apollo was gone. Apollo is an O-3 (Captain).

    It seems very unlikely that Tigh would be an O-5 (Lt. Colonel). He's the XO of a carrier! It's much more likely that both Tigh and Adama are O-6s (Colonels). That's what you would expect to see on a U.S. Navy aircraft carrier. Given the history of the Galactica, Adama might have gotten his promotion and could already be an O-7 (Brigadier General) - on his way to some sort of fleet or staff command once the decomissioning of the Galactica was complete.

    So why doesn't anyone call him "Colonel Adama" or "General Adama?" Because he's the skipper. There's an old naval tradition (not observed, as I understand it, in the U.S. Navy) that the commanding officer of a ship is called "captain" regardless of his rank. However, the CO of a NASA space mission (e.g. a shuttle) is not the "captain" - he's the "mission commander," which you'll hear shortened to "commander" in mission briefings and CAPCOM radio chatter. It's reasonable to think that after hundreds of years of space missions, this tradition might have gained the stature of the naval "captain" tradition. So the CO of the Galactica can be referred to as "commander" regardless of rank.

    Particularly if Tigh and Adama are both O-6s, Adama might well encourage his people to refer to him as "commander" in order to highlight his senior status.

  11. Re:You mean... on Kahle v Ashcroft Appeal Filed · · Score: 1

    Okay, let's talk about "natural property rights."

    Take two cavemen, Og and Ug. The two are equal. If they meet each other at Og's cave, then Ug is weaker, because Og has the support of his many wives and children, as well as the protection of the cave itself. In this circumstance, Og can easily beat Ug to death with a club. If they meet at Ug's cave, the situation is reversed.

    Therefore, Og has a "natural property right" to Og's cave, and Ug has a "natural property right" to Ug's cave.

    Suppose Og writes some etchings on a stone tablet, and keeps the tablet in the back of his cave. Clearly, he has a "natural property right" to ownership of the tablet and to the secrecy of the information contained thereupon. If Ug attempts to steal the tablet, then Og will beat him to death with a club.

    While Og is a great artist, Ur is a mighty hunter. Let's suppose Og goes hungry one winter, so he gives a tablet to Ug, in exchange for half of the carcass of a wooly mammoth. Ug takes it back to his cave. At this point, by "natural property rights," Ug now indisputably owns the tablet. If Og tries to take the tablet back, Ug will beat him to death with a club.

    Now that Ug owns the tablet, he can go in the back of his cave with another stone tablet, and make a copy (to the best of his ability) Og's etchings. Og cannot stop him, because if he tries, Ug will beat him to death with a club. Eventually, perhaps Ug will have dozens of copies.

    Some time later, Lur, a visitor, arrives from his journeys and meets Og and Ug. Lur brings spears of great and awesome quality, which Og and Ug both want. The only item of interest to Lur is the stone tablet. At this point, Og and Ug have equal ability to supply Lur with a tablet. Being a hunter, Ug can sweeten the deal by offering a tablet and the fresh leg of an antelope. Og, who spends his life in anguished pursuit of the etching art, cannot compete with Ug in the area of antelope procurement, and therefore loses the bidding war for the spears.

    Og might wish with all his heart that he could make Ug's tablet crumble to dust by an act of will, but the harsh reality is, Og has no "natural property right" to the etchings once he has given them away. As a result, Og is poor and destitute while Ug prospers and becomes a great chieftan.

    Og's eldest son, Tog, has observed all of this and believes his father to be a fool. Why on earth did he allow Ug to take away the fruit of his labors? Tog matches his father in artistic abilities, but a lifetime of poverty has made him shrewd. When he barters with Tug, he does not offer *copies* of his work. Instead, he offers *performances* such as allowing Tug to come into Tog's cave and briefly view the etchings. Thus, Tog retains his "natural property right" to his creations, while still deriving some value from Tug. Over time, Tog and his descendants become great shamans, equal in power and stature to the chieftans of Tug's line.

    This is the natural state of affairs and this is precisely how things were from the dawn of humanity through to the 17th century, when "copyright" was invented in the modern sense. Prior to copyright, any valuable works had to be either (a) compensated in full at the time of creation, or (b) hidden away and kept secret. Society was better off once copyright law was established, because it made it possible for more artistic works to be available - artists (or their patrons) no longer needed to keep their best works secret.

    So copyright is a good thing, wisely used. But it not, and never has been, a "natural property right."

But it's at least understandable that they are taking the side of the MCSITW (most conservative sysadmin in the world), who would want to hard-code settings on all sides and ALSO find a way to ensure that autonegotiation could NEVER POSSIBLY happen, even if random electrical noise somehow convinced one device that maybe the other one was trying to negotiate with it.

The fact that it's a computer, rather than a typewriter or a video camera, is irrelevant to the discussion of what constitutes an appropriate level of workplace surveillance.

    The act is important, not the instrument.

    If someone comes to your house and uses your telephone, it is NOT legal for you to tape their conversation and review it later - even though it's YOUR telephone. It's not legal for you to beat them over the head with a crowbar either, even though it's YOUR crowbar. At some point, your freedom to act is limited by the rule of law.

    In the United States, it is completely legal for an employer to monitor their employees in nearly any manner they choose, including installing video cameras in every office - so long as the monitoring is disclosed to the employees. In other countries, maybe the rules are different. What we should be asking ourselves is: what set of rules gives rise to the best society?

    If you take this to either of its logical extremes, it doesn't work. In an environment where every action is completely monitored and employees are given no independent freedom to act, the organization loses the power and value of the workers' collective intelligence, which would otherwise have been a substantial asset. Other companies operating in a less rigidly controlled manner will have a major competitive advantage. Note that this is not merely theoretical - the United States' rise to economic prominence was largely due to this very advantage. ("American Ingenuity and Know-How", remember?)

    Going the other way, if rules exist that say that bosses are never allowed to look in on employees - or may only follow rigidly controlled supervisory processes - then the company suffers from free riders, lack of ability to implement its decisions, and general organizational chaos. The worst excesses of "union shops" are an example of taking this too far. I don't have anything against unions in general; I'm thinking only of the cases where the union heirarchy effectively supplants management.
