  1. Re:Completely useless on Why Intel Wants To Network Your Clothes Dryer · · Score: 1

    A killawatt can't turn the freezer to -21C (as opposed to the usual -18C) for a couple of hours with strong winds (and therefore close to free electricity).

    Of course that requires variable electricity prices, but I can't imagine that there will be many civilized places without them in 10 years.

    much less that it needs to eat more than 2 watts 24/7 just to wait for a power-on signal from some lazy fatass who can't stand up and walk 8 feet from the couch to turn it on.

    That can be achieved with less than 0.1W. It's close enough to 0 for me. Mandate that instead of mandating physical switches.

    Maybe I just don't clean enough, of course.

    Just because you reverse engineer something doesn't automatically mean a copyright violation.

    You not only have to reverse engineer, you have to reimplement from scratch. Reverse engineering is relatively easy, the documentation + cleanroom part is hard.

    Your proposal would create additional incentives for people to hide their work instead of sharing it and we have enough problems with that already.

    Practically all software which isn't Free Software is already hidden. For the rest, the source is useless because you still have to do the documentation + reimplementation. It can't get worse.

    What does bundling have to do with the end of copyright? Once copyright is gone, the GPL has lost its teeth, and therefore it can't "protect" us against DRM. That's when the training wheels come off and Free Software will have to win (or not) on an even field.

    Sure, reverse-engineering is theoretically possible, but not feasible. It is not the preferred form of editing.

    The primary reason why reverse-engineering is almost never done is that you can't use the result anyway. Copyright prevents that.

    With copyright gone, reverse engineering tools would become much much better.

    Again, nothing to do with LVM, such a failure will affect any system.

    Of course not. That's what barriers are all about -- making journalled file systems actually work. LVM silently discarding barriers is nasty. Fortunately it has been fixed; I haven't actually tried it out though.

  14. Re:You're confused on Volume Shadow Copy For Linux? · · Score: 4, Informative

    You currently have ext3 fs that are NOT on LVM. In the future, choose LVM.

    The choice isn't that simple. LVM comes with its own complications, including a tendency to get volume offsets "wrong" so the file system data doesn't align nicely to RAID stripes. This is not good for performance.

    Also, LVM has only recently acquired barrier support, and the combination of no barriers + write cache can be quite dangerous if power is lost. Even battery backed cache won't save you if you use a journalling file system (and everybody does these days) because request ordering isn't guaranteed.

    I haven't touched Solaris since it had a 2 in front of its version number, but I must admit that I suffer from ZFS envy.

    That's why the system should have multiple fall back BOPs. AND they should be required to drill a relief well at the same time as the main well, so that if something like this happens, it doesn't take 3 months to stop it.

    Sure, you can require that. However, all this wouldn't have happened if BP had simply required the existing system to be working. If you add extra requirements and the drilling companies ignore the state those new safety devices are in, they will fail too. The human factor is the main problem in this system, and it is difficult to come up with a technical fix for that.

    What they should have is a shaped charge of explosives that can pinch the well bore shut. No hydraulics, just a very primitive electric ignition system needed.

    The existing system would have been able to deal with the problem if it had been broken in just one way instead of having multiple known failures.

    There are set, tested plans.

Well they did a) and it failed spectacularly, so now they're doing b) which takes 3 months.

    In a flow without flow separation, drag increases linearly with speed. With flow separation, drag increases ~ with the square of the speed. Nowhere near the fourth power in either case.

    A scramjet needs to get to about mach 25 to reach escape velocity, which is significantly faster than this test, but give it time.

    A scramjet needs to get to about mach 25 within the atmosphere get to orbit. This means it will either have to accelerate stupidly fast or stay low for too long and burn up. It seems to me that it would be better to go mach 10, leave the atmosphere, and go by rocket the rest of the way.
