  4. The american way and open source. on Tocqueville Blames U.S. IT Troubles On Free Software · · Score: 4, Insightful

    I just love it when people say open source is anti-capitalist and unamerican. I think quite the opposite. It embodies the spirit of America. Capitalism is about maximising profit. Open source achieves that by being free (as in beer) on the whole.

    After hearing at least this argument and the opposite argument (that it's communist) 1,000 times, I've got a neat theory: Open source combines the best aspects of both systems. You get the cheapness, efficiency, and transparency of a free market and you also get the equality and sharing of a communist model.

    Ideal communism (as opposed to Soviet and Chinese communism) doesn't allow for copyrights (it would fly straight in the face of the communal model of sharing), and while the GPL relies on copyright for keeping the source open, under communism you would have to share source code you write, since it belongs to the state for everyone's use, so both achieve the same noble end.

    Free-market capitalism (as opposed to our crony capitalism and corporatism) maximizes efficiency by setting marginal cost to marginal price, which in the case of software, movies, music, etc., is very close to zero. If you supply the resources, like with P2P, it would be free.

    Open source also avoids the pitfalls of both systems. It gets around the state censorship problem by distributing control - anyone can fork off a project is she/he feels like it. It also avoids the problems of monopolists, rent-seekers, corporate censors, and other dirtbags that you find in capitalism.

    How do you know that you don't have any kiddie stuff? 17 year olds look very similar to 18 year olds (which seems to be the age of a lot of porn models). I'm guessing that at least a percent or two of P2P porn is kiddie porn that passes for normal porn or is mislabeled. Even porn from the store isn't 100% certified legal. The studios can get duped sometimes. Might be a good idea to have that porn-shredding Bash script ready just in case.

    For that reason (and that it's a thought crime), I don't think that privately possesing kiddie porn should be a crime. While it might be sick, it makes a criminal out of too many of us (most who don't even want the stuff), and noone is directly hurt (the act of making the junk is a another crime unto itself, unless you can do it without using minors).

    If copyright is repealed (for example) 30% of the economy vanishes overnight. Think the last recession was bad? Think the Great Depression was bad? The number of people who would lose jobs that depend on copyright, patent and trademarks is incredible.

    I guess you would argue that mechanizing the workforce was a bad idea too. Imagine all the employment if crops were grown by hand and thread spun with a manual spinning wheel. Or what about all the jobs that useless government pork generate.

    Jobs are a liability, not an asset, for a country. The goods and services that they produce are the asset. If those goods and services can be attained using less labor, than it is good for the economy as wages can be raised without raising unit labor costs, which means that either the workweek can be shortened for the same pay (more leisure time), or additional goods and services can be made (more stuff).

    Copyright is horribly inefficient (over 80% of labor in copyright industries can be considered waste, lost either in the marketing and legal departments, in the losses attributable to proprietary and closed development and a tiny public domain, or in losses related to selling (as oposed to giving) works such as cashiers and security gaurds). Why not replace it with a more efficient system.

    Information anarchy would work quite well for many copyright industries (music, many books, much softwarem, painting). In some cases, people create plenty of quality works without expecting compensation, like music and open source software. In other cases, like university textbooks, organizations would make sure that new books are made even if there are no copyrights, since they are critical to their organizations.

    Perhaps the gaps could be filled in by philantrophy and government grants. The internet and digital technology greatly reduce the raw distribution cost, and without megabucks to drive up salaries for stars, movies would not take a huge amount of money to make. Government organizations like PBS would survive any transition intact, since they don't rely on copyrights for their revenues.

    I'm not sure of the best way to encourage the production of useful works without copyrights, but considering their cost to society (over 80% of the dollars put into the industry, plus the social and moral costs), most any other way would be better.

    YYYY/MM/DD is good for computers, since it's easy to sort (just a simple 32-bit subcc instruction in SPARC does the comparison, using either binary coded decimal or straight binary), and I would write computer code using that format.

    I use DD-MMM-YYYY (ie., 24-Mar-1562) when writing it for human consumption though, because the day is the most commonly needed part, followed by the month, followed by the year. The first two digits of the year are almost looked at, and a lot of people omit it, but I use 4-digit years and spell out the first three letters of the month so that people make no mistakes about what format I'm using. Only years have 4 digits, "Mar" can only be a month, and the remaining number must be the day.

    But on another note, the elevator shafts provided a lovely rappelling trip... to bad they had to install elevators in them. (Which I mananged to crash and get stuck on the 3rd floor...like software-wise not bloody death crash)

    How do you manage to do that. First of all, since elevator controls are a pure hardware implementation (at least the one in my building), it would be impossible to have a software error. Second, an elevator uses perhaps a dozen flip-flops and a few hundred transistors, diodes, and capacitors, so it's small enough to exhaustively test. There is no excuse for a bug in such a simple design that has been in use for so many decades. Intel manages to make CPUs with hundreds of millions of transistors and only a handful of bugs, and the CPU design didn't exist a few years ago.

    Of course, perhaps they decided to dump the old and proven technology. I can't see why you would need a CPU + software to control an elevator, but if they put computers in the rest of the building, perhaps they figured an extra one couldn't hurt.

  17. Re:Roger Penrose on Calculating A Theoretical Boundary To Computation · · Score: 5, Interesting

    Here's Turing's counter-example to bust Penrose's theorem:

    If a machine (human in this case) can simulate a single Turing machine, and a Turing machine can simulate it, then it is exactly as capable (though perhaps not as quick) as any other Turing machine.

    The first part is easy to prove: Any student who has learned Automata Theory should be able to simulate a Turing machine in their head, though it will be VERY slow and tedious.

    The second is harder, but there is no reason to think that a simulation of every particle that makes up a human, plus a small environment (air, ground, food, water) around her/him will successfully simulate consciousness. The fact that today's computers are not strong enough doesn't invalidate humans being bound to a Turing machine's capabilities.

    Any Turing machine is computational, therefore if the applications of Turing's thesis to humans holds, humans, and every part of them, including consciousness, are computational.

    As far as Heisenburg's uncertainty theorem and quantum mechanics goes, it can be inserted into the simulator using rand().

    Godel's Incompleteness Theorem doesn't apply to Turing's Theorem. Godel is talking about that there exists inconsistencies in any sufficiently complex langage (ie., the statement "this statement is a lie."). It doesn't contradict Turing's Theorem, since to disprove Turing's Theorem, we'd need to find a Turing machine that is incapable of simulating another Turing machine. All Godel says is that there will be non-sensical or impossible states in any Turing machine, but the machine can still work. (the proof that they exist is that English syntax can be programmed into any Turing machine, and the "this statement is a lie." statement inputted into the machine).

    And as far a philosophy goes, so what if I'm limited to 2^2^40 states. I'll never get anywhere near experiencing all of them in the life of the universe, assuming I live that long. And in the same way that computers can execute computer games with fantasy themes, a computation human has nothing interfering with dreaming, pretending, or religion (though it might point out the silliness of latter).

    Generally, when you have words with multiple meanings, the multiple meanings typically reinforce each other (like a drive in football, to drive a car, and to drive a nail). The meanings typically come from someone using an existing word to describe a new action or thing, or because of chance (Sioux Indians and sue as in lawsuit).

    In the case of piracy, it's using a loaded word to chance public perception. If planes were instead refered to as flying bombs, and the media constantly kept calling them flying bombs, people's perceptions of planes would be very different.

    Piracy applied to copyrights might be an old term, but it's still a very biased term. It would be a very good thing to see the word restored to it's original meaning, so, even if it is in the dictionary, I'm not going to use it. Copyright infringement isn't that great a term either, so why not just call it copying or making copies. That term is not loaded and is descriptive.
