    From http://www.tomshardware.com/cpu/01q2/010514/palomi no-09.html:

    "AMD chose two notebook chipsets for Mobile Athlon 4 and Mobile Duron. It's ALi's MaGiK1 and VIA's KT133A chipset. The MAGiK1 is able to run with PC100/133 SDRAM as well as PC1600/2100 DDR SDRAM, but so far we weren't too convinced of its performance in desktop systems. VIA's KT133A is a good performer, but it does not come with DDR-SDRAM support."

    Because of supposed performance problems no vendors have announced any laptops w/ ALi's chipset, so at this point in time the mobile Athlon, which is certainly *my* choice of a dream portable processor, is not being offered with DDR.

    I really wish today we were seeing a mobile AMD 760 or SiS 735 DDR PC-2100 solution, but these chipsets do not have mobile versions.

    Ideally we would be ogling the Athlon 4 on the nVidia "Crush" chipset. As I recall, Crush uses a 128 bit memory bus to DDR memory that allows for a hideous amount of low-latency bandwidth, something like 3.6 GB per second.

    But I digress, it is enough to have a mobile Athlon solution that absolutely wipes the floor with anything offered by their x86 competitor. :) Good for AMD, today is another proud day for them. :)

    And I am sorry if anyone misread my initial comment, DDR compatibility is a function of the chipset, not the processor. Hopefully with the other two explanations I have posted here this has been clarified for one and all. I am off to bed, this was a bitch of a day. ;)

    When I first posted my comment there were no announced notebooks shipping with DDR. Although I am just getting off work and have not yet had time to update from all the tech sites, as of this afternoon (my time) Compaq has announced, and they are currently only shipping with SDRAM on a double-pumped 100 MHz FSB (yes, I know, they call it 200 MHz, and Intel calls their quad-pumped bus 400 MHz.)

    For that matter where's PC-133?

    As far as I know no one has announced a product using ALi's mobile DDR-capable chipset.

    The processor can be paired with any type of RAM the chipset supports, I was hoping Compaq or Gateway would debut a laptop (today) with DDR to really show off the power of mobile socket A. Maybe more products have been revealed since 7 AM EDT. Maybe such a beast is shipping today. :)

    Does intelligence require a mammalian brain? Octopii might beg to differ. Who knows where reptilian intelligence might have gone had the KT impact not occured?

    We are endothermic, we are quick in body and mind, but this does not mean that we are the only answer to the question "what kind of biology is required for sentiency?"

    The only answer we have is "human", but we see hints in the world around us that many different forms can acquire insightful intelligence, so it may be premature (and very Gene Roddenberry) to assume that only humanoids can be sentient. :)

    Heh, regardless of whether or not the asteroid struck near us, if we look at it streaking through the sky it would be the last thing we saw.

    Hint, as we learned from nuclear explosions, very energetic events can radiate significantly brighter than the sun. To keep your eye's lenses from frying your retinas, look away and cover your face with your hands.

    If you manage to save your eyesight, when the brightness fades you may be in for quite a show. The problem is that if you are too close, by the time you see the oncoming shockwave it's way too late to do anything. And this doesn't take into consideration the ejecta thrown into the atmosphere or even into low orbit by the blast.

    Search "tectites, rain of mud, rain of fire" on Yahoo. I suspect the environment gets really biblical after an asteroid impact unleashes a few times the combined total of the world's nuclear arsenals in a fraction of a second (it has happened several times in prehistory.)

  8. Re:A real threat? on How To Handle A Killer Asteroid · · Score: 1

    Um.

    Look at the averages of impacts through the fossil record, far back beyond the KT boundary. There have been quiet periods before. Suddenly an asteroid or a comet gets nudged or bumped in the outer solar system, and Earth has an exctinction event.

    Do you forget that recently we watched a previously uncharted comet smack into Jupiter, Shoemaker-Levy 9? Less than 2.5 million years ago the crater Tycho was carved out of the lunar surface. There's always Tunguska to think about.

    Statistically speaking it is a very safe bet that something already *is* on a collision course with the Earth, we just haven't noticed it yet. Just because no cataclysmic impact has happened within the incredibly brief space of time encompassed by recent human history, you make a very dangerous assumption that this somehow makes such an event less probable.

    That's like someone who lived on the slopes of Mount Saint Helens' om May 17th, 1980 saying "it hasn't erupted in my lifetime, so this means it won't erupt in the future." The next day a gentleman named Harry Truman was proved fatally wrong and buried under several thousand feet of mountainside.

    I for one feel it is safer (and more sensible) to err on the side of caution than to be unprepared.

    The first segment of the cable would fall very slowly dragging along the ground, until friction with the Earth caused it to start wrapping around the planet, then the wrapping effect would create an effect like a figure skater pulling in her arms to spin as rapidly as possible.

    The beginning segment will be moving too slowly for friction to destroy much of it, the middle segment might be finely balanced between friction-heated burning and impacting, but the end segment will be moving at several miles a second, which makes the effect of passing through the troposphere negligible ...

    The cable falling would not split the planet in half as someone else in one of these comments suggested, but someone or something would get smacked, very hard.

    And KSR's "Mars" trilogy IMHO is one of the best sci-fi trilogies ever written. Any truth to Fox TV producing it as a miniseries? :)


  10. Constructing a Space Elevator with Buckytubes ... on Stepping Closer To The Space Elevator · · Score: 1

    The perfect carbon source and counterweight would be a carbonaceous asteroid. We snag one, put it in geosynchronous orbit, and weave the cable downward from it. We pull in additional asteroids from time to time and use solar energy to convert those asteroids' mass into plasma for thrust to keep the anchor asteroid stable. We lower the cable through the atmosphere, and meet it with a several mile high anchor structure/building.

    Sounds simple enough, but I suspect to weave the cable we need to wait for nanotech assemblers, and of course we also have to get out to the asteroid belt and actually do something with them other than bump our probes into them. :)

    The other nice feature here would be the solar farm required for the plasma generation station could later be used to send power down the cable to the large city which would undoubtedly develop around the cable's base.

    I'd recommend outsourcing usenet. Usenet will eat up a *lot* of bandwidth and hard drive space. Let someone else handle it for you.

    Your mileage may vary, but I would recommend a company like SuperNews, which hosts Usenet on their own high availability servers and simply charges you on a per connection basis. Start out with two simultaneous connections.

    People on /. who are knowledgable tend to forget that for 98% of users the Internet consists of email and the World Wide Wait. Usenet usage for the local 2,500 user ISP is never more than ten concurrent connections.

    I find the money an outsourcing company charges per month more than handles the hassle of maintenance, and if they are reputable (and you do not want to become a guru on the subject of usenet) the outsourcing company will supply much more thorough, more frequently-updated access than you could possibly provide.

    In the US there are penalties for renting only a partial circuit, you pay more per channel.

    For those who do not know, E-1 is European/Aussie circuit equivalent to T-1, but due to differences in signaling they get 2048 Kbps, as opposed to the US 1544 Kbps. Sweet, eh? :)


  13. Building an ISP, caveats ... on On Starting a Successful ISP? · · Score: 4
    From personal experience these are the best tips I can give you:
    1. Speak to your local telephone company at length. Ask them questions like "how old is your wiring", "do you support channelized E-1 lines for 56k dialup", "do you use load coils to extend your reach", and "what kind of distance charge do you have for bringing in a data connection"?
    2. You must be a very, very patient person. Be prepared to work long hours with the telephone company and your data connection provider. Be prepared to have them give you conflicting information. Be prepared for your local telephone company to pass the buck for connection difficulties to you. Be prepared to call your local telephone company on the carpet.
    3. Ask your data provider and your telco to provide you with their tech support hours. Ask them for direct phone numbers and contact names. If they limit their hours, ask them if they have extended support options.
    4. Get to know all of your service representatives on a first-name basis. Send them Christmas cards. Be nice to them. You may need to call in favors some time at 3:30 in the morning when your data circuit dies and you have to call their tech support.
    5. Expect to spend more money initially than you bring in. Do not expect your business to pay for itself in under twelve months, meaning have at least a twelve months' supply of operating capital available (the more, the better.)
    6. Suscribe to your competitor's service. You have to know how they perform, they set the standard which you must at least meet, or exceed.
    7. Give referral credits. Give a $5.00 discount on a month's service to anyone who refers a friend to your service.
    8. Pinch your pennies (or your five cent pieces ;).) You do not want to be a dot bomb. Have a three year business plan in place when you start up, stick to it.
    9. You are a utility, not a service. In the rural area where I live I advised the small startup ISP to sell themselves as a utility, meaning they are more like a cable company or a satellite TV provider than a service. In my opinion this helps to foster a "must have" idea in customer's minds.
    10. No one ever brings in a television to their cable company office saying "my TV is not working, what is wrong with your service", but they'll do it to you with their computers. Be prepared to answer all sorts of ridiculous questions, face all sorts of ridiculous situations, and have at least five percent of your neighbors actively hating you. :)
    11. Get an unlisted telephone number. People you do not know will be calling you at home at 4 AM, screaming in your ear, MY SERVICE IS NOT WORKING.
    12. If you are starting with yourself as the only employee, be prepared to forgo a social life. Search "monasteries, coping skills, celibacy" on Yahoo. Implement their suggestions.
    13. Know your equipment. Be prepared to study, study, study. Neither your telephone company nor your data provider are likely to be experts on the equipment you purchase, so be prepared to be on your own in configuring equipment. Before you buy, see if your telco has any prefered RAS equipment. As a suggestion, see if the equipment provider will work with your telco in configuring equipment.
    14. Find a support group. Get in touch with a few other ISP's not in your area. Use newgroups. Keep on good terms with knowledgable friends.
    15. Know your local laws regarding Internet and telecommunications. Get a user agreement, have it gone over by an attorney, and enforce it rigidly.
    16. Finally, never turn down a prescription for Prozac. Prozac is your friend. Prozac makes it better. Prozac may keep you from strangling the next guy who walks in and asks "I just bought a Commodore 64 at a rummage sale, and I cannot wait for you to connect it to the Internet." :)
    17. HEY, which reminds me of one more suggestion -- know your limits. Are you going to try to connect any DOS machines? What about Macintosh? How slow of a modem is acceptable? :)

    At the very least these "doctors" should lose their licenses. At the most they should be charged with crimes against humanity and brought before an international tribunal. The human genome carries the most fundamental definition of "human". To experiment with that, even at the simple level of mitochondrial manipulation without previous debate -- or trials in non-human subjects -- is completely inexcusable.

    These babies may be OK. What if they weren't? Don't these doctors accrue some penalty for performing experiments on humans?

You will be lucky if you do not have one fire per year. The Ostankino Tower in Moscow was the world's second-tallest freestanding structure, and was supposedly impervious to flames. Thankfully it was mostly uninhabited, which kept fatalities to a minimum.
