  1. Re:Ubuntu on How To Speed Up Linux Booting · · Score: 1

    in both my newly installed feisty and the old edgy my computer hangs during boot for about 10 minutes, unless I disable apci. then it boots up in about 45 seconds. Noone has been able to tell me so far what to look for. and yes I've looked a dmesg I have the line that it hangs at.

    I have seen those signs. I have also seen reflectors that change color at or near freezing temperatures. I'm not quite sure how they work but they are very helpful when you're not sure whether that big hill is covered in ice or not. btw these are in Truckee, California on Northwoods blvd I believe.

  4. Re:Group Velocity Again on Speed of Light Exceeded? · · Score: 1

    although there may have been some sarcasm in the post, I was for the most part being serious. If the cars were all wired together sure they could all stay at the 5 foot interval and I suppose it would be a wave action. (hard to visualize for me but I kind of like the 2 light-year long scissor analogy). I was kind of talking about why it takes so long for traffic to clear. also while racing at 200 mph I've never seen anyone slam on the brakes and come to a stop or care if they bump into one another. the one car length per 10 mph was just what we were taught in drivers ed. I also realize that there are a lot of other factors involved as well.

    Disclaimer: this post assumes you don't live in LA
    everyone stepping on the gas at once is not an accurate representation of what would actually happen. There are unaccounted for factors(other than coordination). When people are stopped in traffic, they inevitably park 5 feet from the car in front of them. 5 feet is far less than a car lenth. while traveling at high speed you need to have approx 1 car lenth per 10 mph. so 60 mph is 6 car lenths. 5 feet translates to a few (56) milliseconds at that speed so 6 car lenths is maybe 2-3 seconds.
            If you have 1 mile of cars stopped on the freeway (in one lane) that's (on average) 176 cars. i'm using 25 ft car lenth with 5 feet in between. So for that single mile 176 cars have to wait 1.946 seconds to get the "proper" distance.
            This doesn't even count the people that don't realize what's happening, having to combine 2 lanes of traffic into one or the jackasses that switch lanes to get in the one that's moving, thereby stopping traffic behind them for a fracking mile.

    We could use a Large Magnet. Then tether it the the earth with a long nano-tube cord slap and elevator on it, power the elevator with microwaves or lasers or solar power on the satellite (they make conductive nano-tubes now) and then we could call it a space elevator. I believe that it would require a large weight to counter-balance it. All the weight we need is probobly up there. I know that the magnet would obviously not collect "all" the trash, but most likely a good bit. Space Elevator Conductive Nano-tubes

  11. Re:Making money from electric co on Running Your Electric Meter Backwards · · Score: 1

    Actually power companies do this with two lakes. one being at a higher elevation. during off-peak hours they pump water into the upper lake(storing the energy) and during peak hours they let it flow back down. they use the same pumps to generate the electricity. it is only about 35 percent efficient but that is still enough to overcome the price difference. the price difference is much greater that 20 and 40 cents.

  13. dell inspiron on Durabook Laptop Marketing Claims 'Destroyed' · · Score: 2, Informative

    I dropped a dell inspiron of a roof once, and it ran fine with no damage whatsoever. granted it was in a leather laptop case(that wasn't zipped up). It rolled end over end down a steepish roof and fell about 20 feet to the ground. I was doing a site survey for wireless internet and it stayed where it was until I walked away.
