    As a more dramatic addition to the story of projectile weapons, the Pope outlawed crossbows.

    My details here are sketchy, but my understanding was that because of the terrific power of the crossbow to puncture platemail. Which meant that a commoner could kill a knight. Couldn't tell you which pope though.

    While I agree insofar as materialism is the result of questionable moral choices, I've never felt that capitolism is an ideal means to manage scarce resources. And medicine is an excellent field in which to discuss this.

    Antibiotics and HMOs. People are dying for the profits of others (kidney patients are more likely to stay on dialasis until they turn yellow and die than get a tranplant under HMOs. 20% more than not.) under a fairly well controlled capitolism.

    Antibiotics are prescribed to patients who won't complete the cycle, breeding hardier germs. Anyone remember the TB upswing? And now, to push their products, dishsoap, "fresh" scent sprays, ever children's toys are being made antibacterial, which has the same effect, only moreso.

    Which is not to mention the (I feel) natural push towards monopoly and the results that has for everyone. If nothing else, capitolism leads naturally to mediocre software. Compare Windows to Linux. One was produced by market pressure and voting with dollars. From the theory, you'd guess it was Linux.

    I don't propone Socialism; people may be dumb, but a single person tends to be evil. I'd rather have herds of blind self-service than centralized enlightened self-service. I stil wonder about whether an alternative economic system would be possible...

  3. Re:This is interesting. on Reverse Time Could Explain Dark Matter · · Score: 1
    What happens when two adjacent but opposite-flow time zones hit the exact same moment, then? They have to at some point, after all; it's a case of meeting in the middle.

    While this is not as obvious as stated, it is provable. However, I wonder why it should confuse? The regions as described are not co-spacial, and for a moment would be co-temporal. But you and I are co-temporal at the moment. So what?

    More interesting, I think, are the implications of entering such a region of space. Not the actual being there, so much, as considering the interface of normal and reverse time. (Now here's a "seems obvious" assertion: One region's reverse time is indistinguishable from the others. Betcha that's not true, but I can't say why...)

    What I mean though is, so much elementary physics presumes that time flows in one direction (if not neccesarily at uniform speed). While the interface is singularly thin, there's a width where time is flowing one way on one side and the other on the other. Quick way to be out a watch, if you see what I mean...

  4. Re:This can't be open source! on Distributed Computing and the Human Genome Project · · Score: 1

    You need to sequence the gene first. This is the long and costly part if I remember well. This is silly. The sequencing is the computer intensive part. You need to take the chunks you've got and attempt to line up the overlaps to make larger chunks. So passing out a hundred or a thousand or however many sequence chunks to be compared and good matches returned would be an excellent way of doing things. And would have the side effect of publishing results; necessarily you'd be handing out copies of the longer sequences you've established, until everyone who wants it has the whole sequence. (Although, I think it's kind of large, bitwise.:)

    I strongly disagree. AIUI, DB2 was designed for one purpose: beating the Grandmaster. So, IMO, it was a bigger kludge than a hack. A hack would have been a general purpose chess program that could win. Not what amounted to a patch on DB1 so that it would be fit for one purpose.

  6. Generic Solution on Public-key Based Streamed Encryption? · · Score: 2
    While not a crypto expert, I do have a passing knowledge of RSA and some conception of digital security.

    However, it seems to me that as stated, your problem has two immediate solutions. First is buffering bits until you have enough to properly encrypt. While you couldn't use full PGP in this (since digesting won't work), doesn't RSA operate on single chunks of the plaintext, so you could buffer to the appropriate length and use RSA. This might make your crypto vulnerable to frequency attacks, if they're appropriate to the plaintext.

    It occurs to me that some sort of random delay on the buffered packets, together with ordering information within the encryption, would destroy this attack potential, though.

    The other solution approached the shortcoming of the first that it infringes on the real-time-ness of the stream. For mission critical streaming, it might be sufficient to use a pad at the beginning of the message, determined by a challenge-response or some such. (Honestly, I have an even vaguer feeling for challenge-response crypto and security, so this might not be as helpful.) Anyhow, if a garbage string of sufficient length could be added to the beginning of messages, you could accomplish bit by bit encryption without loss of security in early communication.

    Of the two, I definitely favor the first, if for nothing other than error checking. It also seems to be the more secure of the two, and a trade off in security to simultaneity can be made in the length of packets, in extreme cases, or for extreme control methods (or on noisy lines) and in the maximum shuffling that can occur. This results in fairly predictable delays, since the length of packets times the maximum hold order (how many packets late it'll be) gives the minimum buffer length required, and thus the minimum delay.

    Again, you might use the second in cases where the demand for synchronization is so high that it defeats the first system. However, I'm still uncertain how to arrange for the padding. Perhaps more conventional PGP or something could be used to establish the transmission?

    Finally, I'm honestly curious as to what other /.rs believe would be better: error checked(&corrected?) encrpytion, or encrpyted error checking. Again, maybe it doesn't matter if you aren't doing mission critical data, or data that can take errors okay, like voice or images, but in any other case, it should be required.

  7. Tesla on Broadcast Power? Wireless Energy? · · Score: 1
    This may get Moderated as flamebait, but I'm really not trolling here. I personally am sick to death of reading and hearing about Nikola Tesla the misunderstood genius. From what I've seen as far as application, and from primary sources (published lectures) Tesla has always struck me as being enthralled by high voltage.

    That's it. High voltage is cool. Some neat applications, and it doesn't work like the rest of electronics, since Kirkov's Laws cease to apply ( as they do at high magnetic flux and high frequency (an interesting point to recall as you continue to overclock ) ). And Tesla was a genius at producing high voltage current. But...

    I find that too many people are too credulous when it comes to Tesla's claims of what he could make electricity do. I mean, the man claimed he could cure cancer with current.

    He was enthusiastic, commendably so but a poor scientist. His presentation I was fortunate enough to read essentially ran "Lookit the cool spark!" He gushed about how high voltage was the solution to everything. And it really isn't. Tesla magnifiers terrifically clever, and make high voltage a reality in the garage. And there are defintely cool applications for them.

    A lot of what he was talking about was blowing smoke. He had a lot of unscientific, unuseful theories. Like the Earth's "natural vibrations."

    Pretty much he hit on some cool stuff and never accepted that it wasn't magic.

    On the other hand, try looking into Micheal Faraday, who was to electronics what Gauss was to math. Before Ohms, he was experimenting with electric dissociation of chemical compounds, and relating it to current. And where Tesla was slinging EM fields without really knowing much about them, Faraday developed means to shield them out, and quantified what it took to shield from differing fields. (Faraday Cages.) Liken them to a kid making gas bombs and a geek developing internal combustion.

    But that's plenty ranting today.

    Question 11 is (I think) a web spin on a short story by John Brunner called "Who Steals My Purse." I'd ruin it if I went much further, but I think the situation is so close to the story it would be hard to believe that the author of the exam hadn't read it.

    Besides, Brunner is one of those authors, like Stephenson, who appeals greatly to the hacker in me. Brunner was predicting the internet in the mid Sixties. And a nomadic American populace, moving from job to job amazingly frequently. (The Shockwave Rider). Brunner was, in my opinion, more visionary than any other science fiction author, especially in the wisdom of his predictions.

Essencially, the mixer slider is a really nice potentiometer. Use an A/D converter after contraining the amperage from the slider. Then all you need is a counter to get the freqeuncy output right. A PC parrellel port needs to supply a single signal ground and a clock pulse from your driver. The rest can be pulse based signals from your sliders. Kind of like servo control but not really. Hm.

Then MAYBE they could pull that kind of nonsense and say "We have DVD2K!" and make it backwards compatible with the other side of the market's product. I suspect that a monopolistic player company would have an easier time of it.

    Then they could redo the security of it, and expect results. Some extra features wouldn't hurt, but overall, all they'd really need to do is make the play. In the most ideal situation a partnership of two huge companies would be required: one to produce DVD2k players with backwards compatibility, and the other to make DVD2K discs out of all the new content they could lay hands on.

    However, I don't think we are anywhere near that kind of situation. The cost-of-duplication argument aside (because it's silly; I heard that one when CD-R was just starting), to circumvent the clusterfuck they've invented would destroy the DVD market as it exists now.

    Granted, the flip side is that when the glitch gets fixed, no one hears about it, since the company in question is desperate to keep that sort of information quiet.

    Finally though, what would the fix have been in this case? Not to continue the license to XingDVD or RealNetworks? Their key would still be plaintext and useful for guessing new keys.

    Furthermore, what could the fix be now? Scrap this DVD standard and replace it with a new one? A resurgance of DIVX(fie!)? You're dealing with an existing hardware market that is just beginning to take off that you would be completely destroying if you scrap the existing security. Any new security system would have to be a superset of the old one, which mean it would be no more secure.

What that means is that when there are candidates and issues that fall on economic lines, the Voice that gets heard is the voice with money. The flip side is that publicly financing political campaigns (if you include all statements endorsing or detracting a candidate) means ultimately either limiting how many people can say what they want (effectively putting a price, or a limit on 'free' speech) or financing the world. That's a tight little dillema, quite appart from "it cost my parents thousands to raise me, so are my political conjectures made by a PAC?" type absurdities. The absurdity is an artifact of the paradox. The real problem is that the ACLU and the FEC are both taking (fair typically) bloody-minded stances.
