  1. Re:Seriously, a practical implication? on Wolfram's 2,3 Turing Machine Is Universal! · · Score: 1

    Abstract notions like computability on Turing machines and NP completeness are most useful to prove lower bounds, eg. what cannot be computed at all, or not efficiently. For example, the general access control problem is not decidable. Thus, don't waste your time on it, but shoot for something less general.

    Perhaps a TM can have an application, but that's not the only point.

  2. Array origin fun on OSX To Feature Portable User Accounts? · · Score: 1

    Further classification of the population: those who can tell an array's last element from its length, and those who cannot.

  3. Re:It's not "googol," it's "google..." as in Barne on Gap Between Google and Competition Widening · · Score: 2, Informative

    One-to-the-hundredth power is a "googol."

    Actually, it's one.

  4. Re:Meat-Eaters Aiding Global Warming? on Australians to Get Compulsory Photo ID Smartcard · · Score: 1

    my debate team had a rebuttle argument called "meat."

    Seems a decent limits-to-growth sort of argument, perhaps simplified somewhat. Not sure if it's relevant all the time though.

    There is very very large difference between Czech and Bulgaria, Ukraine and other eastern European country.

    As soon as the west calls again, your Slavic brothers are rapidly forgotten...

  7. Re:Natural on South Korean Music Retailers Dying · · Score: 1


    Do you really trust the political system to fund a network of paid musicians, movie studios, and writers (plus whatever other forms of entertainment you lump in there)?


    Sure, many European films were funded mostly by public money, and turned out infinitely more interesting and innovative than the vast majority of privately funded Hollywood movies. And from which production model do you see more provocative and subversive material?

    Check out some Cuban films sometime. Those sure weren't privately funded for profit!

  8. Re:Diesel with or without Biodiesel is a good star on Saving Energy Without Derision · · Score: 1

    I highly doubt a 2003 VW diesel pollutes more than a gas version. This technology has improved lately, and diesel fuel can be cleaned of many pollutant-causing components (and it is in Europe as I recall). and if you go to biodiesel, then where's all this nasty pollution coming from?

  9. Re:health risks? on Philadelphia Considers Free Citywide Wireless Access · · Score: 1

    Adverse affects on health by wireless, especially in such large roll-out, are still not entirely proven harmless.

    Does anyone have pointers to how WiFi EM radiation relates to that of mobile phones and towers? Perhaps Phily will be the first long term study on the subject.

  10. Re:Out of Curiousity ... on RPOW - Reusable Proofs of Work · · Score: 2, Informative

    > ... how much does a IBM 4758 cost?

    In the region of $2000-3000 when they were still being produced. I've seen them for sale for $800 or so more recently. So not that much for any kind of org.

  11. Re:Zombie farms on RPOW - Reusable Proofs of Work · · Score: 1

    So you want industry controlled crypto hardware in your machine that you have no conrol over? That is TCPA/Palladium?
    Because thats exactly what that IBM board in the box is. Guess that's how you sell Palladium to the slashdot crowd. Tell them it will "stop spam" by having your computer to a whole lot of calculatin'.


    My impression for this scheme is that the IBM 4758 goes in a server somewhere, quite different from TCG etc. Usually the point is that it looks out for your interests on the server. At $2000-3000 a piece back when they were still being produced, they probably won't find their way into too many PCs.

  12. Re:Pfft. on A Solution For Making WiFi Cost Effective · · Score: 1

    I had the impression that authentication is done with ppp, and CHAP should be able to deal with an insecure connection medium, yes?
