    Where do you think hydrogen comes from? Ok, it comes from water, but it takes power to extract it, a little more than you are going to get back when you use the hydrogen in a fuel cell, or a LOT more than you'll get back if you fuel an engine with hydrogen. Hydrogen cars would put the same load on the power plants as electric cars do. Plus which the idea of some dolt hotdogging down the freeway with half his SUV occupied by a tank of highly compressed hydrogen bothers me for some reason...

    For fixed installations (power plants, heating, etc.), hydrogen does have some theoretical advantages. You could generate it from solar energy in Arizona and pipe it to places where there isn't enough sunshine to make solar worthwhile. That's assuming that someday we'll be able to make solar panels that are (1) cost effective, and (2) don't create more pollution in their manufacture and recycling than a well-filtered coal-fire power plant would. But hydrogen in mobile applications is nuts.

    ALL events can theoretically be traced back to a specific cause.

    Wrong. Quantum events are inherently random and not predictable. All you have to do is to amplify such events into strings of 0 and 1. One example is radioactive emissions -- if you can keep the source and detector in the range where you count one particle at a time. That's rather difficult to do in a way that's both safe and will keep running without adjustments. Another possibility: resistor shot noise, which originates in the fluctuations as individual electrons pass through the resistor. I am not good enough at analog design to figure out just how to use that, but it should be possible to generate random numbers from shot noise in a small circuit with common parts.

    If you are generating pseudo-random numbers entirely from software, then it is predictable, if you can guess the formula used. The simple formulas you'll find in pre-packaged "random number generator" subroutines are probably easily guessed. Go to a cryptographer and you can get formulas that are alterable by plugging in a secret key of hundreds of bits, so even if the basic formula is publicly known, guessing the key takes enormous computer power...

    No, the numbers aren't instantly recyclable. Scroll up to the part where someone says that retailers are required to keep the charge slips for 3 to 7 years. They attributed this requirement to charge-backs, but I think 3-6 months would be sufficient for that purpose.

    However, the number of people alive now is a 10-digit number, so (even ignoring that most people on Earth now will never have a credit card), a 16-digit number with one digit for checksum provides 100,000 numbers per person. I don't think they'll have to recycle the numbers too fast.

    There definitely were religious wars between Buddhist sects in the middle ages, not to mention that Japanese sect that used nerve gas a few years ago. These incidents do seem to be less frequent and involve fewer killings than the ones arising from the Judeo-Christian-Islamic traditions, but they do happen. I think the difference is not deism or non-deism, but rather that the Buddha's works are very clearly against violence. A murderous Christian is a bad Christian, but he can find scripture to quote out of context in support of his actions. It's very hard to see how a murderous Buddhist could fail to notice that he was a bad Buddhist...

    "If an organization wants to copyright their material or mark it as a trade secret, that's their business." The issue is just what they are trying to protect -- sometimes it would seem to me to be against public policy for a court to help them keep their secrets. It can be a corporation that doesn't want it's manual instructing customer service people on how to stall and lie exposed to public view, or a religious organization that doesn't want it's manuals on how to get the maximum contributions published.

    The news article is pretty confusing, and seems to have various concepts mixed up. Or else Swedish laws are decidedly strange -- if the work was unpublished, then why is copyright even at issue? And IANAL, but it can't be copyrighted and a trade secret both... But whatever is going on, it should be legal to cite portions of a copyrighted work under "fair use" in an article criticizing the organization that issued that work. Putting the whole book on the web is indeed a copyright violation. So remember--just use the embarrassing parts, intermixed with your commentary...

    Uh, do you know what "sarcasm" is...

    And evidently you missed the news reports about the Taliban (Islamic fundamentalists in Afghanistan) destroying Buddhist statues from the time of Alexander, for fear that someone might worship these idols. And if anyone thinks that's just a Moslem peculiarity, the Judeo-Christian Bible contains the same prohibition against worshipping grraven images. Catholics and many Protestants use a very narrow interpretation of that: they aren't worshipping that statue of Jesus, just using it as an aid to concentration on worshipping Jesus -- but it looks a lot like worshipping the statue. But the Catholics used to be pretty intolerant of anyone else's religious icons, for instance the Spanish destroyed most of the history of the Mayans as "idols". And even among modern-day Christians, Jehovah's Witnesses take that commandment quite seriously, and if they were in power I think they'd be dynamiting statuary.

  15. Re:I'm speechless... on One Click Setback for Amazon · · Score: 1

    There are big problems at the patent office in finding prior art in business methods and software patents. Some of the problems have to do with the PTO budget (too low--Congress is stealing part of the fees for other agencies) and the bureaucratic incentives (examiners have a quota # of cases to close per month, the fastest way to close a case is to grant the patent, the PTO only gets sued when it doesn't grant a patent, and nothing adverse happens to an examiner who grants a bad patent). But the biggest problem is that the PTO almost entirely relies on their database of patents to research prior art; since software and business methods used to be non-patentable, the prior art isn't there.

    Sounds like prizog has the simplest idea--while hacking the MD5 code is probably way beyond the understanding of the slackers that spend all day on napster, "run this program on an MP3 and then Napster won't reject it" is simple enough for any drooling idiot who can operate a mouse. And I think that program would be written about 10 minutes after someone who understands the format first realizes that an MD5 code check is what's preventing him from getting pirated music anymore.

    Not that I approve of piracy in general, but the RIAA seems to be shooting itself in the foot, repeatedly. The artists are almost ready to give away their recordings, because the RIAA has their royalties so low they make most of their money on live performances anyhow. The consumers were buying CD's on the basis that they liked the MP3's ripped from them -- now that's more or less blocked. But what I'm really waiting for is for the RIAA to impose ever more onerous restrictions on Napster, until even a dimwitted judge is going to notice that what they are really doing is blocking the distribution of music that they don't own.

  18. MD5??? on Napster to Filter by Filenames · · Score: 1

    Could you explain more about the MD5 sum? Text searches are easy (as long as it's for exact text), and in this case all they have to search is the names submitted to their database. If it can do the name searches to match requests to available files, it can also look for the name in a blocked list.

    I assume MD5 is some sort of file checksum. That is, you have to fetch the file to find it, rather than just looking at the database listing. That puts quite a load on Napster's pipes. Maybe you have to add up all the bytes in the file to calculate it -- that's quite a computational load, plus it means Napster has to download every file they list, and takes a lot of bandwidth. Or maybe the MD5 sum is pre-calculated and embedded in the file header?

    In any case, couldn't you just add .01 second of silence to the end of the file and change the MD5 sum?

    Calling what CA did "de-regulation" sounds like a leftie plot to destroy the meaning of the word.

And then they capped the price of power to the consumers.

Erroneous mathematical notation aside, what he was trying to say was that the area goes with the square of the display size.

    I think that has been done, to cover the walls at the NY Stock Exchange with displays a few years ago. If I remember right, 20-some inch LCD's cost $25,000 then, and they bought hundreds of them. Stockbroking must be a mighty lucrative business. These were considerably lower resolution than the ones described in this article, but they were intended to be read from across the room. This also helped with the dead zone that you are bound to have at the edge of any LCD display; at a minimum you have to seal the edges, so the liquid crystals can't go all the way to the edge. If you are going to be reading it from 10 feet away it isn't visible, but on your desktop it would be highly noticeable. Most displays also have a protective case around the edge so the glass doesn't get chipped, etc., so I assume the NYSE special-ordered their displays "bare".
