    The hard part is where do you pull FROM. If it's like the poster said and 100+ outside, you're 'cooling' your servers with 100 degree air, and it's a convection oven for everyone inside that room.

    If you're pulling in the air from an air conditioned part of the building, you're just 'stealing' cold air from that part of the building and pulling it through your servers; you're also losing a lot of that cold air around the servers unless you isolate your hot/cold sides like some colo facilities do. Now we're at the point where you still have AC or chilled water, you're just not dumping the heat back into the same room, assuming you properly isolate and don't simply let the cold air slip around the servers and out the door.

    Might want to think that through. The superior weapons are only worth anything if the government wants to rule rubble. If so, then we're screwed and so are they.
    More likely, the tactic would be occupation which requires lots of people on the ground and you're not going not to get far if one in 4 people have a gun and just 1/10 of them shoot at you. Imagine how badly a march through a town 2000 would be if 50 people with the element of surprise and home court advantage are shooting at you. Imagine if you end up in a town with a 60% firearm ownership rate and half of them are shooting a at you.

  11. Re:Time to move. on FBI: We Need Wiretap-Ready Web Sites — Now · · Score: 4, Interesting

    Not resisting and/or taking a stand also have serious consequences in a world where people who resist can be 'black-bagged'. When no one fights back, the oppressor just gets bolder and the oppression more universal.

    If the government will black back you for fighting back, then you had every right and perhaps even a patriotic duty to fight.

    If a person believes that their spouse will kill them if they leave, that's all the justification they need to leave. They have to take that chance, they have to leave and they have to fight back. Relenting or rolling over only guarantees you get hurt. Even if you die fighting back may at least stop them from hurting anyone else.

    The same goes for the government. We're guaranteed to be oppressed if we stay quiet and do nothing. We may force them to reconsider if we fight back, if nothing every one of them we kill (yes, we're talking about killing them) is one more that can't hurt your neighbors, friends, family, enemies, people you have no connection to whatsoever, etc.

    If corporations didn't have rights, does that mean the government would be free to send the police in and search their premises at will? How about seize all their belongings and the contents of their bank accounts whenever they felt like it? Could corporations be subjected to trial without jury or representation in a kangaroo court?

    Corporations having rights means that the people who comprise that corporation don't lose their rights because of how they choose to associate.

  14. Re:I approve on Cell Phone Jamming Devices Enjoy an Increase In Popularity · · Score: 1

    There won't be a signal at the output if the input antenna loses its connection to the carrier.

    We dealt with this recently at my job. The antenna outside our building to Carrier A became misaligned and we began having a lot of problems with cell phones for carrier A. At various points in the building, your phone would only have a weak connection to a tower outside our building, OR it would roam to Carrier B (who had also picocells at all the same places as carriers A,C, and D).

    Without a signal at our input side, the outputs in our building didn't broadcast any signal. It wasn't an unmodulated carrier or anything along those lines, there just wasn't anything there as confirmed by a spectrum analyzer and near field detector. Once the outside antenna was fixed, we could see signals on the frequencies for carrier A and our phones stopped dropping and/or roaming.

    I shouldn't have said repeater, as the picocell heads are a lot like wireless access points that are centrally controlled. Wiki article on picocells.

    In any case, the point about repeaters (picocells) is that many larger businesses get companies to install picocells in their building. That is a de facto denial of permission to jam. If they didn't want cell phones usable in their building, they wouldn't have gone to the extra trouble to have extra equipment installed inside to facilitate it.

    The same goes for nearly all subways and underground trains. The chances of their being picocells all over the place is very high. The authority in charge of that area CHOSE to have cell phone coverage extended down there and went to some kind of effort to get a company to install them. This too should be treated as a denial of permission to jam.

    The other problem is that many times the person claims the jamming signal is confined solely within their property/building/domain, yet the jamming signal affects those outside of the jammer's property. That becomes a huge problem.

    Those who wish to stop cell phone use should first STOP installing indoor repeaters, then use some form of radio wave blocking paint/building materials. Whatever method they use should be passive and not directly interfere with other property's cell phone signals.

    They're still morons, and short sighted morons at that.

    The number of people killed and injured due to the nuclear plant issues PALES in comparison to the number of people killed by the tsunami and earthquakes.
    A 40+ year old nuclear power plant had serious issues following an unprecedented tsunami generated by an unprecedented earthquake, and somehow that's evidence that nuclear power as a whole isn't safe.

    They should realize that the number of deaths/injuries from this incident are far fewer then the number that would have died or been sick in the last 40 years if their power had come from the other major power production methods of the 1970s. Anyone want to guess how much pollution a 1970s coal, oil, or natural gas power plant would have put out and how many additional people would have been sick or died prematurely compared to the number during the nuclear period?

    Going forward, they still have to use something to generate power and solar won't provide them with the power they need, esp with its high land costs. They may have to go with clean (or at least much cleaner then in decades past) coal, or natural gas. I wonder what the pollution numbers on those two sources will be compared to a modern (read:1980s) nuclear power plant.

    Everything I've read about black-boxes and event-data recorders suggests they're all in a loop.

    Airplane black boxes apparently run on a 30 or 60(?) minute loop. What's being recorded now is overwriting what happened 30 mins ago. When an event occurs that stops the recording, there's a snapshot of the time running up to the event. I understand it's a 15-30 second timeframe for automobiles and airbag deployment.

    There are driver monitoring systems that work the same way. There are videos on youtube from companies that make products for companies that records driver behavior-they record G-forces, delta-v, directional change, and speed; some can also record throttle and steering angle, etc. as well.
    They run on something like a 2 minute loop and if certain thresholds are exceeded, will commit the last two minutes to some form of non-volatile storage and continue recording on a new two minute loop.

    I've seen videos and read things that led me to believe that there are some models of police dash cam systems that operate like that. Running on a specific timed loop, but stopping the recycle part of the loop when the lights or siren are turned on.
