  1. Re:Grub and Windows on Ubuntu 8.04 Beta Released · · Score: 1

    Look at /etc/fstab and think about it.
    That's exactly why you don't use things like /dev/hda if you want to switch drives around. Ubuntu (or any other distro that cares to) uses UUID to define everything in fstab and the root argument in GRUB. UUID is set when the drive is formatted and as such doesn't depend on the physical location and won't change.

    Unfortuantely you still have the (hdx,y) setting in grub to change and maybe a reinstall of grub depending on exactly how everything got switched around, but no messing around with fstab or boot arguments are necessary. I've used UUID regularly to set up frequently mounted external drives in fstab so I could mount them quickly without needing to know what order I connected them in.
  2. Re:Other home dangers! on Questions Arising On Mercury In Compact Fluorescents · · Score: 2, Informative

    (I find it interesting that you mention mercury being used in thermostats; every home I have ever lived in used metal coil thermometers; I guess its where you live)

    Uh... that's how mercury thermostats work. A bulb with a drop of mercury in it is attached to a metal coil. The coil expands, tips the bulb and the mercury drop slides to the other side and closes the electric circuit. To change the temperature the furnace comes on you just change the angle of the glass bulb so it has to tip farther for the mercury to slide to the other side. What other designs using a metal coil are there? The only thermostats I've seen are the type I just described and completely solid state.
  3. Re:Simple solution. on Drugs In Our Drinking Water · · Score: 1

    Actually in the most recent reports, just about all the land in the north half of Iowa is valued on average over $4,000 per acre. I've been hearing people either celebrating that their land is worth 25% more than the last survey or whine about how expensive that is.
    It made me realize I really need to move somewhere where the price of land isn't a prime topic of conversation.

  4. Re:Private Flights? on British Airport Will Require Fingerprints From Domestic Passengers · · Score: 1

    Why would private flights be at a terminal? If you don't go in the terminal obviously you won't get fingerprinted.

    Also, why would private flights be more likely to have criminals aboard? Do you have any idea how much an airplane costs, even to rent? Especially in Europe where they get really screwed over with taxes and user fees. Even crooks have a budget.

  5. Re:Use capacitors on Cold Reboot Attacks on Disk Encryption · · Score: 3, Informative

    I heard that mechanism in hard drives explained to me as using the spindle motor as a generator to get the heads parked. Makes sense, there's a lot of inertia in the spinning platters that you may as well use.

  6. Re:My experience differs on Xbox DRM and the Red Ring of Death · · Score: 1

    If you'd actually read the page you found, you'd realize that it will create the same problem talked about in the article. After transfer you'd need to be connected to xbox live in order to play downloaded content. That situation isn't acceptable.

    http://en.wikipedia.org/wiki/Redshift

    The picture at the top of that page is a pretty good explanation. Basically you just take the absorption lines of some known materials and compare them to the absorption lines seen in whatever is being observed.

  8. Re:O rly? on Hostile ta Vista, Baby · · Score: 1

    Judging from the text of that article (no, I haven't read any others by him) it sounds more like "Frequent Slashdot Troll" to me. Basically it's a few obvious observations (plus some whining) about vista, with a few ignorant statements about linux thrown in for good measure.

    Newegg is a shopping site, not a magazine. Are you really going to tell me you'd get better recommendations from best buy or some other site?

  10. Electronic Control in 1972? on Stopping Cars With Microwave Radiation · · Score: 1

    While some electronic control systems may have been available in 1972, it seems like computerized engine controls weren't really popular until around the mid 80's. I know of plenty of cars built in the early 80's that had pretty primitive carbureted engines, with no computer system and maybe just a few basic electronic sensors. How effective would this be on a car without a fully computer controlled engine? Wouldn't the engine need significant electrically controlled systems for this to even work? I'd guess that most cars built through the 70's would be immune to a system like this.

  11. Re:Warning: Idiots Overhead on Where Are the Flying Cars? · · Score: 1

    What I really have a tough time believing is that they would be able to sell this for $148,000. The Cessna Skycatcher is a light sport aircraft (a certification mentioned in the summary) and it sells for around $110,000. The price they are selling it for is not unreasonable at all.
  12. Re:hmm on Where Are the Flying Cars? · · Score: 1

    I can see a lighter aircraft than what we have today landing on a public motorway I regularly fly aircraft that weigh less than the car that I drive to the airport. We already have aircraft that are plenty light to land on a roadway. If they're a really light two seat aircraft, they could probably land and take off in less than 500 feet(if there are no obstructions around).

    It would probably take very little change to the roadway system to make it possible to put little 500 ft landing strips in a few places. Or stores could just stick them along the edge of their parking lot. Of course there is the safety issue of aircraft flying at low altitude over densely populated areas, but I'm just saying that room to land really isn't a reason that flying cars would be impractical.
  13. Re:hmm on Where Are the Flying Cars? · · Score: 1

    my mom's neon would leave this thing in the dust I will confess, I have not read the article, but the summary refers to it as a light sport aircraft. If it really is a light sport aircraft, it weighs less than half of what a neon does. With that in mind, 100hp is plenty to make this thing speedy on the ground.

    The summary also makes a comment about people without licenses flying. Light sport aircraft require a license. To fly without a license it needs to be an ultralight. 100hp in an ultralight would really make that thing quick, but you can't carry more than the pilot in an ultralight.

    Off topic, but even with those very basic errors in the summary, this article is still better than most of the sensationalist crap about aviation on slashdot.

    I don't know if this applies to all Seagate drives or not, but I do know that all the desktop seagate drives that I have don't display SMART data correctly. I'd be willing to bet that number is complete crap, along with most of the rest of the SMART data.
