  1. IMHO, this latest tactic... on SCO Gives Friday Deadline To IBM · · Score: 1

    reeks of barratry. They've sued, and are now unwilling to wait for a trial _they_started_? They're trying to force IBM to settle, when their only legal recourse is an injunction or trial? Huh?

    No kidding! I'm 38, and haven't written anything cursively since about the 3rd grade. I can keep up just fine, and you're a lot more likely to be able to read my printing than my cursive writing.

    Why do we have 2 different character sets again?

  3. Re:Diversity in a small group on Have Humans Come Close To Extinction? · · Score: 1
    ...people that have never been exposed to members of a different regional group of humans do have trouble seeing differences between them as well...

    Agreed, but they don't have any trouble distinguishing them from any _other_ group, including their own. Any human can readily see the differences between what are commonly called 'ethnic groups', whatever the underlying genetic meaning,if any. I don't remember ever seeing an analog among other primates. How does the genetic diversity of, say, cats or dogs stack up against that of chimps? Has being domesticated and gentically artifically manipulated raised their level of diversification beyond that of chimps? Or people?

  4. Re:Diversity in a small group on Have Humans Come Close To Extinction? · · Score: 2, Interesting

    Unlike our close genetic relatives - chimps - all humans have virtually identical DNA. In fact, one group of chimps can have more genetic diversity than all of the six billion humans alive today.

    Why doesn't such impressive genetic diversity in the chimp world translate to more obvious facial/structural diversity as is seen in the wildly differing appearances of humans?

    To put it another way, if they're so genetically diverse, why do they all look alike? I'm sure Jane Goodall, et al, can tell different troops and individuals apart, but I sure can't. Perhaps chimps think we all look the same, huh?

    I could imagine a 2.4GHz 'stripline' loop (or semi-loop) yagi made of copper tape glued to the outside of your body tube. Naturally the reflector(s) would be up, and the directors down. This would be fairly directional, depending on the number of elements.

    Alternatively, wrap the copper tape helically around the body tube, matching the sense of your ground antenna.

    Good luck!

    Hams are not allowed to transmit music via a phone mode, i.e. J3E, A3E, F3E, etc. Digital music (and pictures, for that matter), as long they are not facilitating anyone's regular business, are fine. I can legally stream my MP3's via amateur radio all day long (with proper ID, frequency and mode selelection, and station control, of course). The data is not encrypted, it is encoded and compressed - perfectly legal. Bits is bits, I always say.

  8. Re:We landed on the moon with 512 bytes of RAM on Mars Failures: Bad luck or Bad Programs? · · Score: 1

    It's nearly impossible to find space-rated, radiation-hardened components that are anywhere near 'cutting edge'. The smaller the process, the more likely the component will be damaged by radiation - that pretty much eliminates 'cutting edge' stuff and newly shrunk old stuff.

    It's really a shame that manufacturer's can't easily produce space-rated components cheaply, and it's also a shame that the space-rated component market is not large enough to support that niche as a viable business.

  9. Re:Indian president is a technocrat.. on President Of India Advocates OSS · · Score: 1

    As regards India's president---I really think they need a reformer who's willing to dismantle their caste system rather than a technocrat.

    The latest edition of National Geographic has a startling article on India's caste system. If you think US minorities have the hardest row to hoe, check out this article.

  10. Re:design by committee vs. standardize afterwards on Are Standards Groups Stifling Innovation? · · Score: 1

    When committees design things from scratch you get horrendously overcomplicated things like X.509...

    Or SNMPv2. What a mess. I agree with the 'from scratch' comment, but I'd add that standards designed in a vacuum with no 'community input' (Java logging; are you listening, Sun?) typically are bloated and unusable.

    the Communications Act of 1934 did not do their homework. In 1986, a huge body of law was enacted in the US to "prevent" listening in on cell phone conversations and any other communication "not intended for your receipt". The text of the ECPA is not very useful in itself; you must read the redacted Title Title 18 USC, Sec. 2510.

    Issues of load-based meltdown aside, token ring has one property that ethernet does not - token ring is deterministic with regard to delivery time. When you're writing B-52H simulator code, you _really_ want your frames to get there on time, every time. (where a few milliseconds late means glitchy flight).

  17. Re:TCP/IP on 30 Years of Ethernet · · Score: 2, Informative

    Uh, UDP is a member of the TCP/IP suite of protocols (ethernet protocol number 0800). So is ICMP. ARP (number 0806), however, is not. As far as protocols _over ethernet_, see this list of assigned protocol numbers over ethernet.

    Protocols within TCP/IP are assigned numbers as well. See this list of IPv4 protocol numbers for more info. TCP packets are tagged as IP protocol 6, UDP are protocol 17, ICMP are protocol 1, etc. They are all ethernet protocol 0800, however.

    • Drilling (yes, drilling!) a friggin' hole in the coax, getting little bits of shield shorting it out, causing the whole segment to die?
    • Those manly N connectors?

  20. Re:Cool on Diamond-coated Steel · · Score: 1

    Diamond is a very good conductor of heat. To wit:

    In general thermal conductance tracks electrical conductance, metals being good thermal conductors. There are exceptions, the most outstanding is that of diamond which has a high thermal conductance, between 1000 and 2600 Wm-1K-1, while the electrical conductance is low. Thermal conductance of other common materials: Silver 430 Copper 390 Gold 320 Platinum 70 Quartz 8 Glass 1 Since diamond has such a high thermal conductance, natural blue diamond much higher still, one may test gems to determine if they are genuine diamonds using a thermal conductance tester, one of the instruments of gemmology. Diamonds of any size are notably cool to the touch because of their high thermal conductivity, perhaps the origin of the term "ice."
