  1. Self-describing medical instructions on Training Nurses With Virtual Veins · · Score: 5, Interesting

    My wife had a plant safety class where they learned CPR from a paramedic who specializes in training. She had tattoed instructions on her arm how to do CPR, with an X on her wrist saying "Check here for pulse" and an X on her chest over her heart saying "Push here"

    People should come with operating instructions :)

  2. Let's do some bandwidth math... on Cray CTO Says Cray Computers Are Great · · Score: 3, Interesting

    From Cray (From XD1 page):
    "A 96 GB per second, nonblocking, crossbar switching fabric in each chassis provides four 2 GB per second links to each two-way SMP and twenty-four 2 GB per second interchassis links."

    -So for a dual-opteron XD1 processor unit, there is 8GB total bandwidth available.

    Total aggregate PCI bandwidths (Accepted standards):

    PCI32 33MHz = 133MB/s
    PCI32 66MHz = 266MB/s
    PCI64 33MHz = 266MB/s
    PCI64 66MHz = 533MB/s
    PCI-X 133MHz = 1066MB/s
    PCI Express = 200MB/s (Per slot)
    PCI Express x16 = 3000MB/s (Usable bandwidth)

    -So for PCI Express x16 we're talking 3GB/second

    SMP Opteron with two PCI Express x16 slots can do 6GB/second aggregate bandwidth. A couple of Infiniband links can easily saturate that. I'm sure this all costs quite a bit less than Cray's propriatary stuff.

  4. Re:Vendor lock-in mentality? on Real Feels iTunes Backlash · · Score: 4, Informative

    >Apple's codec sucks compared to even MP3

    What was the format of those tracks? What bitrate? What makes you think Real is using their own codec for the iPod (It isn't, the iPod can't play RealAudio) What music store sells MP3's? (OK I know of ONE, but I doubt anyone has heard of any of it's bands) AAC compressed music actually sounds pretty good at comparable bitrates to MP3.

    >I'll continue to stick to SHN/FLAC

    Then your portable music player must have FLAC/SHN support and a gargantuan hard drive for the terrible 2:1 compression ratios you get. MP3/AAC usually gets about 10:1.

    >Perhaps these Apple lovers have become so accustomed to vendor lock-in

    You mean the way the Realaudio music store ONLY WORKS ON WINDOWS?

  5. This has been around for a long time on Cooling Toronto Using Lake Ontario · · Score: 3, Informative

    Geothermal has been around for a long time. There are closed loop systems that put the condenser coil underground, and open-loop systems that use streams (ideal) and ponds (somewhat less ideal)

    The General Motors Technical Center in Warren, MI has been using open-loop cooling for decades, using the large pond on the campus as an open-ended evaporator. The fishes that live in it don't seem to mind.

    There's a nice picture here:

    MacOS 9 (I'm assuming you don't mean OS9) is actually a pretty good server platform. It's hard to root something that has NO remote access by default. Heck, if you 0wn the webserver (MachTen, AppleShare IP, or WebSTAR) all you can do is change content. If you're lucky you can maybe run some system-level AppleScripts, if security is turned way down on the server.

    I guess XP Media center is quite a bit different, but XP Home is mostly a stripped down XP Pro, with more wizards and different control panels. 2000 Server and 2000 Advanced Server have a bunch of extra server apps, and completely different kernels and base drivers (for SMP and big memory support) when compared to 2000 Pro.

  9. Jeeze, it's BIG on Complete List of Bugs Fixed in SP2 · · Score: 1, Interesting

    250MB+ of patches? Granted it includes WMP9, and a bunch of IE stuff, but previous service packs (2k/NT) covered multiple versions of the same OS (Win2k Pro, Server, Advanced, etc...) This is 250MB of patches for ONE version of ONE OS.

    To be fair, I guess it would be similar to a point release for linux, updating the kernel, glibc, gnome/kde, mozilla, etc... It would probably be at least that big. It's still kind of freaky installing that many patches simultaneously.

    I remember updating Netware 3.x using patches on floppies, one after another. It was a pain, but at least you knew exactly what's getting installed and when.

    Flash devices only have a read/write cycle of a few hundred thousand. Sounds like a lot, until you realize that the file table gets written to at least that much within a year of use. I'd go for a battery-backed SDRAM array, say PC-133-ECC. Pricewatch has 1GB sticks for $160. That's 10GB of ultra-high speed storage for $1600. Add a couple hundred for a memory and SCSI controller, a few batteries, and you're golden.

  15. Re:We already have sustainable nuclear fusion on U.S. Cancels Fusion Program · · Score: 2, Informative

    Solar energy is not reliable, anything less than clear sky and the system isn't running efficently. Photovoltaic energy has expensive delicate solar panels you have to protect. Photothermal has huge arrays of mirrors you have to maintain and protect. Unless you are in a desert or Arizona there's not much hope for solar.

    Geothermal is great as long as you live near a volcano or hot springs. Geothermal heat pumps work great, though expensive.

    Tidal and wind farms kill fish and birds respectively, so you have Audobon, Greenspeace, etc etc after you.

    What makes you think evildoers won't own any of these alternative energy sources? They have a vested interest in maintaining their position in the energy market, and if people swing towards alternative energy they are going to be involved.

    ... Which is fallwell.com is NOT falwell.com. If they were trying to profit from the mistype I might buy some claim of domain sniping. If Falwell (the man) wants to protect himself from lookalike domains/tradmarks/whatever, he can register every permutation of his name with Network Solutions/the trademark office. Otherwise he should be SOL.

    I know the courts are swinging in the favor of broad interpretations of trademark (Witness the horrendous Uzi Nissan case, nowadays the bigger company wins the trademark, even if you were first and legit) This trend is wrong, shortsighted, and introduces far too much subjectivity in the area of trademarks. I bet the lawers love it!

I would think a dual 3.6GHz Xeon would be able to beat an Athlon FX64, but I'm not sure about a dual Opteron. I know most games aren't written to take advantage of SMP, except for Quake 3, but you do see *some* performance increase when one processor can take over menial system tasks and audio processing, leaving the other to play the game.

    So how about it Anand (Or Tom, or ars) High end workstation game shootout! If you want a baseline I'll give you VNC to my dual Xeon 1.7 box :)
