  2. Can't prove a negative on Cellphone Number Portability -- A Big Lie? · · Score: 1
    Although a small number of people disagree it is widely believed you cannot prove a negative.

    So there will never be proof that RF doesn't cause cancer. Ever. Just like you can't prove Santa Claus doesn't exist.

    However, there's no way for your tissues to tell the difference between a UHF TV transmitter 5 miles away or a low power cellphone held up to your head.

  3. Easy way to memorize maps on US Military Builds MMO Earth Simulator · · Score: 3, Insightful

    Imagine "Blackhawk Down" set in 2005.

    What if the troops have no idea how to get home when their chopper is shot down or the natives put up another barricade?

    A 3d environment like this is a very effective and fast way to memorize the map and layout of the city.

    Also good for convoy training, preparing for ambush training, etc.

    I have no relation to www.unitednuclear.com other than being a happy customer.

    How are we "Lucky" that TMI didn't "Chernobyl"?

    The Chernobyl accident boils down to to reactor overheated, the graphite (purified coal) moderator caught fire, and vaporized the core all over the place. White hot coal does tend to catch fire you know.

    Now in comparison, TMI overheated and the water moderator... didn't catch fire.

    Boy we sure are "lucky" that water doesn't burn as well as coal. I guess it's all just luck that water didn't catch fire.

  8. Re:RF Hazard? on Could Broadband Over Power Lines be Dangerous? · · Score: 1

    What about cheap breakers, switches, and dimmers that depend on switching during the AC zero-crossing interval? Won't the presence of even a tiny bit of superimposed HF keep the arc alive in a circuit breaker until it incinerates the device?

    Also losses in the cables will be immense so both the headend and subscriber boxes will have to use huge transmit power levels, so the level might be low at the middle of the cable but the transmitters might have to be dozens to hundreds of watts (?)

  9. Re:Aircraft ILS and power-line transmissions on Could Broadband Over Power Lines be Dangerous? · · Score: 2, Informative

    Frequencies are wrong for ILS which runs adjacent to the VHF comm band, more or less.

    Far more likely, was an IFR NDB approach where they were trying to use the NDB to avoid the mountain, unfortunately they managed to avoid the interfering power lines instead, thus hitting the mountain..

    NBD freqs are in the 200 to 500 khz range which is adjacent to some of the signalling done in the sub 200 Khz range.

    The point of a T1 is you're paying big bucks for techs whom are highly trained and will dispatch at your convenience to fix even a suspicion of a problem 24x7 including holidays.

    A collector would likely have paid alot for that machine. I know I would have given you maybe $100 for it depending on media and docs, and I'm relatively poor and cheap as far as collectors go.

    Search ebay to see what a classic pdp-8 goes for now, generally more than a good used car is worth. Admittedly a pdp-8 is a little more popular, but I'm sure you could have gotten a heck of a lot of "beer money", or at least someone would have hauled it away for free, saving you the effort.

    Power48 runs on palms and palm compatibles and it emulates a HP48 at the hardware level.

    It is, however, slow and locks up by sony SJ-33 rather often.

    It's not as good as a real HP48 because there is no keyboard so it is very hard to tap and click as fast as you can type on a real HP48

  15. Re:Issues of Weaponizing this System on Simcity Microwave Power by 2050? · · Score: 3, Informative

    Low beam density makes it a useless weapon.
    The whole concept is that you could make a system with a beam density low enough that the focusing antenna is reasonably small, yet, with the beam density high enough that its not cheaper to just slap down solar cells on the ground.

    Essentially you are getting more power from the cells in space, so as to offset the transmission and "shipping" (rocket launch) costs.

    Look at the nasty chemicals the power lines use, such as creosote and god knows what else in the wood power poles to prevent rot, incredibly toxic weed killers, nasty PCB based cooling oils in the transformers...

    The chemical waste spread underneath and along a power line will kill you dead, the EMF effect, if any, is unimportant.

    For those whom don't get the joke, basically the ratchet heats up by impacts until its position is too random to gain energy from the impacts. Also the ratchet is flexible making it's position random. Really the same anyway, heat equals vibration.

  19. Re:Processors dying... on The Cost of Distributed Client Computing? · · Score: 1

    The practical effects of temperature cycling will kill the chip long before simple high temperature kills the chip.

    Thermal cycling from "room temp" to "too hot to touch" will eventually embrittle the wires that connect the die to the chip carrier (you know those little golden ones you see under the microscope). Then bump the case and the brittle wire cracks. Much like how thermal cycling eventually causes a copper car radiator core to crack after a few thousand heat/cool cycles.

    Temperature cycling also makes chip connections to the sockets "loose" over time.

    You are better off running the chip at a constant temp that is within it's design limitations.

  20. CVS on Distributed Filesystems for Linux? · · Score: 2, Insightful

    CVS.

    It's got powerful replication services, although manually run.

    Disconnected operation is no big deal with CVS.

    As for distributed file systems, make one system the CVS server. Make sure all your systems "cvs update" by a cron job that runs often. If the main server explodes, your next task is to set up a new server. Set up your DNS so cvs.whatever.com points to your current CVS server, and keep a hot standby ready. Change the DNS to point to the new CVS, CVS commit from any of the slave servers that were doing "cvs update" every 5 minutes, and you're up and running again. Could automate it, if I had enough problems to make it worthwhile.
