    Alrigty, show me where I can sign up to get 48V DC power delivered to a data center.

    As you explained, that would be silly. What would NOT be silly is 400V DC or perhaps 15kV DC for a large data center.

  2. Re:Making green energy from nuclear energy on Storing Wind Power In Cold Stores · · Score: 1

    This is done a lot in Norway,

    There they have double water dams/basins one high one low.
    During peak hour the water is rushed down for electricity.
    During night they buy cheap French nuclear energy to pump water back.


    I don't doubt that they do this, but I doubt that much electricity from France is involved. The Scandinavian grid and the Middle European grid are not synchronized, so only DC links between them exist (or perhaps AC links with phase regeneration, but does anyone do that anymore?) The amount of electricity that could be moved is rather small -- there has been much talk about increasing capacity, but has anything really happened? In fact, if I read the map on GENI right, the Norwegian power grid is somewhat wimpy and reliant on the Swedish grid. That's the kind of thing you can get away with when you have lots of hydro spread across the country, but not the kind of thing for major energy import/export.

    The point was the irony of having voice recognition text entry on a phone for the purpose of communicating in written form when you could go directly with voice.

    I understood the irony. It is still a feature I would like and use. Because SMS's are polite, whereas phone calls interrupt.

    There is a reason that autonegotiation is often disabled & it's called experience...

    Usually it's called resistance to change. I haven't seen any trouble since around 2000. Except when the idiot at the other end of the cable locked it at 100-full, forcing my end to go 100-half. Luckily that problem is gone with gigabit, since that is autonegotiation or nothing.

    AC induction motors are more efficient than DC motors - that's why all modern electric and hybrid cars use them and an inverter rather than a DC motor with PWM.

    None of the efficient AC motors run on fixed 50Hz AC. If you want efficiency, you need variable frequency. If your fridge isn't ancient, it rectifies the AC to DC and then back to AC. Getting rid of the AC-to-DC bit would be nice.

  8. A 2% improvement is HUGE on Linux 2.6.20-rc6 Kernel Performance · · Score: 2, Interesting

    Kernel developers regularly hunt elusive speed boosts which can only be detected by specialized benchmark. 2% on something as generic as kernel compilation is fantastic.

    Of course the tests probably weren't conducted in a sufficiently scientific way, so the measurement error probably swamps the 2% improvement. If it can be independently repeated, congratulations are definitely in order!

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

    What is to prevent people from storing electricity (in batteries) during off peak hours and then selling it back during peak hours and generating a profit?

    The electricity companies would love it if you do that. Off-peak prices (wholesale, untaxed) sometimes go as low as 0.01USD/kWh around here. If they can sell it to you for even 0.05USD/kWh, that's a nice profit. On the other hand, at peak times inefficient generation methods are used, and production price is really high. They would be very happy to buy the electricity back from you, even at peak price.

  10. Re:Intellectual property on Apple/NVidia Driver Bug — Question Deleted · · Score: 1

    The command registers are stored in the drive not the controller. Updating the system to deal with large disks is a device driver issue, not a hardware issue.

    That is how it should be. However, ATA controllers have in some cases grown a bit too smart -- some of them interpret commands before they pass them on to the drives. 48-bit-support is done by sending the address in two cycles instead of one. Those "smart" controllers get confused by the second address cycle. Yet another case of PC hardware designers being crazy.

  11. Re:huh on Undersea Cable Repair Via 19th Century Tech · · Score: 5, Interesting

    It's reasonably easy to find a cable. At those depths the cables lie directly on the sea floor, and if you run a hook across the sea floor from one side of the cable to the other, you'll cross it by definition. Sure you might then end up some distance from the break, but they are apparently reasonably good at handling that. Such techniques don't work with shipwrecks -- and even if they did, there may not be anything the right shape for a hook to catch.

    Anyway, there's an old but interesting article on undersea cables by Neal Stephenson.

    Why would Metacity want to prevent the configurability?

    You'll have to see if you can find their reasons on the web somewhere. Searching for gnome configurability on Google and Groups got me some results, but not something definite to link to. Perhaps you'll have more luck...

    Anyway, to solve your specific problem, you can actually assign a keyboard shortcut to "maximize vertically" to Metacity with gconf-editor. Not as good as what you really want perhaps, but it might tide you over. In the process I discovered that click-to-front is known as raise-on-click in Metacity, and that it can be turned off! Yay!

    This is actually a window manager thing, not something to do with Gnome or KDE. It's not particularly hard to accomplish with old-school window managers, but modern ones like Metacity deliberately prevent such configurability. Personally I'm just waiting for a modern window manager which lets me turn off click-to-front off.

  18. Re:No change in sea level. on Arctic Ice May Melt By 2040 · · Score: 1

    What if this warming trend is part of a natural cycle? Do the environmentalist just want to sit back and let the environment do its thing then?

    I consider myself an environmentalist, and if global warming turns out to be natural variations, that probably also leaves some hope that it will naturally vary back down. At least the likelyhood that we'll experience runaway warming seems low, if it's all from natural causes. Therefore we can be a bit more lax about trying to stop it -- it isn't likely to kill us. Except if the natural cause is the sun getting hotter or something else which isn't likely to reverse, in which case we should still combat global warming just as hard. As long as we keep everything mostly the same, the Earth has a long history of being a relatively benign place for animals and plants, and therefore we can have some confidence that it will continue to be so. The problem is that with the atmospheric contents changing dramatically, we cannot rely on past experience.

    If natural variations turn out to be a threat to humans, I am all for fighting them.

    Are the keys stored somewhere else on the disc, like the innermost plastic area before the data area begins?

    They are stored in an area on the normal writing surface, but standard writers won't let you write that area, and standard burnable disks have that area pre-recorded.

    Theoretically, you could do a bit-for-bit clone of the DVD disk, and, in this manner, you wouldn't have to decrypt it in order to copy it.

    This is actually easy. The trick is that you don't get the keys copied when you try that with a regular DVD burner or regular DVD writables. Therefore standard players are unable to decrypt the copied DVD, so you can't actually watch it. Certain players CAN play it though, the ones that break the encryption instead of asking for the keys. In most cases removing the encryption is done when copying, since it's just easier that way -- but it isn't the only way.
