    I think the point of Google's system is its not 'answer these questions' (plural) its 'answer this single question' (singular). its meant to be fast and unobtrusive. 1 click and you are through. IF that is truly the case, then i can see there system working. Otherwise, its like you said, people just fake it, or leave, and find the information elsewhere.

    For a great example of paint weighing a lot, look at the space shuttle. Ever wonder why the external fuel tank was orange? well, if you look back at the footage, the first few external tanks where painted white. The orange is the sprayed on insulation on the tank. after the 3rd one, someone at Lockheed (who made the tanks) realized that they could save 600lbs of launch weight by not painting the foam after it was sprayed on.

    No, this is not an excuse to cut down trees. Its an excuse to grow more, and cut down on the amount of waste that is discarded from what wood products we use. TFS even stated that CNC is made from 'wood chips and sawdust' which was, until this product was discovered, a trash byproduct of the lumber industry.

  5. Re:Mars does have air pressure on MIT Works On Mars Space Suit · · Score: 2

    You are right, the effects of a vacuum are vastly overblown in movies and books. The first thing i looked up when i saw the comment about punctures in the summary was this http://www.geoffreylandis.com/vacuum.html which includes a bit describing when one of our astronauts had a 1/16th inch hole punched through his suits glove. The same page goes into some details on the effects of vacuum on people.
    part of people's problem with vacuum, is they seem to mentally correlate it with pressure like on a submarine. In a submarine, at depth, you have thousands of pounds of pressure pressing inward on the hull, and a puncture is catastrophic, a needle of water that can cut like a razor. people mentaly invert this situation when thinking of vacuum. They assume the same is true, only in reverse.
    The truth is, the difference in pressure between the inside of a space craft, and the outside vacuum is more or less 1 atmosphere. That is a *tiny* amount of force. which is why they could build the lunar lander walls 'the thickness of a couple sheets of tin foil'.
    the reason our current suits are so bulky is not mainly for puncture prevention (although there is some of that) its largely for insulation/radiation barrier. and to cover the large amount of weird gear that the astronauts wear to stay at a safe temperature. a suit of underwear with tubing knitted in that carries liquid that is either warmed or cooled, depending on what the need is, among other things.

    the problem is, a huge swath of people would have to go rob a bank on the way out of town in order to fund your little scenario. For the lower middle class and below, options consist of:

    1. Die.

    2. Become a hermit mountain dweller somewhere in the Rockies. Preferably in northern canada, where no one lives.

  7. I read an article where someone did this. He posted on the internet a picture of himself, and the challenge that he was dropping off the grid, and whoever 'caught' him got a reward. (I think it was through a newspaper or magazine, he was a writer). He moved around the US a lot, doing odd jobs, paying cash for hotels and rents and everything. His stipulations where that he had to remain in some degree of contact with his editor or something. He lasted like 5 months if i recall, before someone spotted him in a pizza joint and called out the capture phrase they had set up at the beginning. He said it was the most stressful months of his life, and he was not even in a situation where his life depended on staying of grid.

    That was my thought. There literally are no 3G towers in my area from *ANY* provider. Verizon claims they are bringing one in 'spring 2012', but that has yet to materialize. I guess this gives us a timeline for 1 of two things:
    1: AT&T's national coverage map is going to shrink massively in 2017 2. AT&T gets off its ass and upgrades a LOT of towers. i'm going to Occams razor that one to the cheeper solution.

  11. Re:Stick With What Works on Ask Slashdot: Best Way To Take Notes In the Modern Classroom? · · Score: 1

    I go with ink on paper. I discovered (much to my dismay) one semester that after 3 months of hauling around my notebooks packed into my backpack, the first 100 pages of my pencil written notes had basically been smudged off by the pages rubbing together and where nearly invisible. The pages where just sort of grey, with very faint text on them. After that, I switched to pens, and a 'Day Binder' system. red binder for M,W,F classes, and Black for Tues Thurs classes. less to carry, and less chance for things to smudge off.

  14. Re:Beware the batteries! on Ask Slashdot: Storing Items In a Sealed Chest For 25 Years? · · Score: 1

    don't include the battery then, just a power supply. most laptops will function without the battery as long as they are plugged into the wall. As for the battery in the PC, you are thinking of the CMOS battery. A laptop would have one of these as well, but I've had computers in closets for decades that never showed any indication that the CMOS battery leaked, so i figure its a non problem. If you are really worried about it, remove the battery, and place it in some other sealed (non conductive) container.

  15. Re:good in theory, bad in practice on Indoor Navigation On Your Smartphone, Using the Earth's Magnetic Field · · Score: 1

    the variance in the magnetic field is the POINT here. the are mapping these subtle/dramatic variations, and using them as measurable waypoints for navigation. (ie, there is a lot of magnetic field outside the GAP in this mall, but a lot less in front of the dip'n'dots, and there are a series of spikes by the fountain across from the dillards etc. etc. etc.) yeah, sure you can wipe out the magnetometer with a field coil, or (maybe) make the map return bad results by throwing 50 hard drives in a trash can, but for the most part, this seems like a smart way to map indoor areas for electronic navigation.

  23. Re:You can never get rid of the dust! on Sandia's Floating, Dust-Free, Spinning Heatsink · · Score: 1

    with this setup, that is a reasonable possibility. The video indicates that with this device, cooler outside air enters the center of the fan, takes up heat, and exits the sides. with the appropriate housing, an air filter could be installed on the intake of the fan. if/when this becomes publicly available, I foresee case mods with little duct to the outside of the case and have the filter externally accessible. Any number of air filters from the automotive world cold be adapted, and you then just have to remember that your computer takes an air filter from a 2009 model Jetta or something. I wonder why this has not happened already. You already change the filters in your car, your home AC, etc, why not do the smart thing, and add filters to your desktop tower?

    1. dust. its everywhere.
    2. its bad for computers.
    3. People that actually care about their computers may actually try and clean their house, and not leave there computer under their desk on the floor where it is going to draw in every single particle of filth in the house.
    4. there is no four.
