  1. Evil Ground Loops... on PC Not Booting Until a Different Phase is Used? · · Score: 1
    Spooky stuff like this is usually bad grounding. The machines in question are connected to each other, right? (network? serial port? some such...) and the ground voltage is different, causing current through the system when the others are up but its power is off.

    I'd look into the docs on the UPS you have to see if there is a way to hook up a ground lug on the *output* side of the UPS to tie it to building ground. I'd also get one of those testers over at Home Depot to see if your outlets are all actually grounded.

    I bet if you leave it plugged into the wall, and unplug the *other* connections (network, video, etc.) for a few seconds, it will come up.

The professor at the front of the room calls out that it's time to put the pencils down and start turning in the papers, which everyone dutifully does, except for one guy in the 5th row, who is still scribbling away furiously. Exams are collected, students begin to leave the auditorium. The guy who kept on writing finally gets up, and walks up to the TA who is standing by the big stack of exams. The TA says "Forget it fella, we won't take it anymore." The student says "Do you have any idea who I am?" The TA replies "Well, no, there are 2000 people in this class..." The student says "So you have NO IDEA who I am.", and the TA says "Yep." So the student picks up part of the stack of exams, drops his in, and puts the stack back down.

    The other big problem is perennial budget uncertainty -- National Labs never know from one year to the next what their budget might be, as it literally takes an Act of Congress to renew the funding each and every year, and especially the last few years, it's rarely been anywhere near on time. Add to that the fact that sometimes the DOE takes budget back partway through the year...

    It means that things you should buy, but that aren't absolutely critical, often get delayed until the Mad September Purchasing Rush, when folks actually know what's left in their budget. This can mean that new database server to let you build the tracking system for something you really ought to have been tracking already is delayed 6 months to a year... Or you don't get training you should, or hire staff you should, not because there isn't budget for it, but because you don't know if there is budget for it.

It's against my religion to take the Pledge of Allegiance, but they do that in most schools in the country; I learned early on you can say "WHY pledge allegiance..." and nobody can tell the difference.

    • Drilling in the ANWR -- A damned shame, but barely a scratch in the surface of our overall environmental/climate quagmire, and a complete diversion from the real related issues (e.g. stopping the use of petroleum for fuel, etc.)

    Most of these issues are in fact short-term smoke-screens, designed to get you emotionally riled up; but when you look at things like what actually kills innocent people in large numbers, (even if you count embryos as innocent people, depending on your religious leanings) these issues don't even make any kind of a prioritized list.

    Instead, we should be

    • massively improving education (class sizes in the 5-10 kids/teacher range), so that we have more graduates capable of contributing to the remaining items.
    • (Here in the USA, anyhow) ramping up the CDC, FEMA, and other organizations that directly save lives, rather than cutting their budgets and responsibilities.
    • Similarly putting way more money into similar United Nations organizations.
    • Figuring out how to run our economy without fossil fuels, and how to get the C02 levels in the atmosphere back down.
    • completly redesigning transportation to be orders of magnitude safer and not use non-renewable fuels.
    • take our most efficient helthcare system (Medicare, not any private insurance company) and take the age limit out of it, and give it to everyone.

    That seems to me one of the things folks are overlooking here; the documents are being stored in OpenDoc format. They can be converted to at least 2 dozen other formats, automatically, for folks that want to read/use them in that format. That's the whole point -- it's a format which can be converted to current (and old) word processer formats, and will continue to be able to be converted to other formats as needed, since we have the source code that knows how to read the format to be able to build filters/converters, and will continue to be able to use that code, even if assorted companies go out of business, shift formats in a new release, whatever.

    This choice of how documents are stored has absolutley no effect on who can read the document, because it can be converted to whatever format they need on the fly.

    If they have root on that system, they can read anything on that system, and that's the end of it. You can hide it/obfuscate it N different ways, but they're all fixable -- in order to run it on that box, the perl text (or some equivalent transformation) has to be obtainable on that box for perl to execute it. And if it can be obtained to run it, it can be obtained to read it.

    You might have enough limits with a BSD jail, or a virtual machine layer, to keep them in a subtree somewhere, but you're still going to have to call out of the jail/virtual machine to let them run the script, so it's the same archetecture, just a different network.

  15. There are two aspects on Should Linux Have a Binary Kernel Driver Layer? · · Score: 1
    ... license/GPL issues, and technical issues.

    I actually think from both perspectives a clean binary driver API could be a Good Thing, especially if it involved some sort of sandbox that such a driver would be kept in, and even more so if it could be a common binary API between, say, Linux, BSD, and possibly one or two other OSes.

    • You wouldn't have to rebuild/rerelease such a driver for each release of the kernel. this would be really nice for distros, a kernel update wouldn't have to include rebuilding the ABI-compliant drivers.
    • If your code is sensitive to optimization flags, etc. it can be compiled "properly" once and not redone wrong by various distro builders. (yeah, yeah, it probably means the code actually sucks, but...)
    • It would provide a clean boundary for the GPL-ness of the kernel; this gives you a way to encircle vendors who think their code must be proprietary -- they keep a minimum amount of proprietary code, and we encircle it with open, clean, GPL code. Then those vendors can see how much business they get from Linux users, and start to take Linux users concerns (like GPL-ing their drivers) more seriously.
    • You could build software adaptors that let you take drivers for other platforms (MS Windows? OS/2? BSD?) and load them against a Linux kernel; and you could do it once.
    • You could also build software adaptors that provide trace/debug/trace-playback information for these ABI drivers, which could make it easier to debug problems.
    Now of course, you could do the last two with the current, source-code driver interfaces; but they would be (in my opinion) much harder to maintain without the sort of set-in-stone nature of an ABI driver interface.

    I know some folks will argue for some sort of GPL purity -- that Linux should actively avoid any and all contact with proprietary code. But being able to run proprietary user-level code is actually a feature that lets you displace proprietary operating systems, and I think the same thing is true of drivers. And once the proprietary-driver vendors discover they can make money selling their hardware for Linux, they might discover that having their customers be able to send them bug fixes as well as bug reports is a Good Thing.

  16. Re:Yawn. Another crackpot needs funding. on New Discovery Disproves Quantum Theory? · · Score: 1
    Well, I'm not a particle physicist, but where I work you can't swing a dead cat without hitting a few dozen of them, so here's my best misunderstanding of it:

    Quantum physics models do state that various things happen in discrete quanta -- i.e. you either transfer a photon, or you don't -- but that doesn't mean that there is only one such quantum level of change -- different frequencies of light are photons at different energy levels, etc. (here's a calculator to find the energy of photons at a given frequency)

    So when you hear someone talking about transferring half quantums of energy, they probably just have the frequency wrong... There are also, as I understand it, systems where you can jump something up two energy levels with two photons, and then emit one of a different frequency in one double-level jump (like those cards to help you see infrared led's at Radio shack, you charge them up with blue or green light, and then shine a remote control at them, and they glow visible red from the infrared pulse).

    So it is possible there is a system where normally we double-jump energy levels in both directions, and there is a halfway level you can get to with the right frequency of photon; but that doesn't gut/break the model, it just means there's a very rare state that got left out of the model. Of course, there should be a corresponding gap in the overall energy of the model if that were true, as I understand it, and I don't think CQM has such gaps left in it anymore; but I suppose there could be a gap so small it's basically round-off at 6 or 7 signifigant figures. But it would be correspondingly really really really rare, so being able to provoke such a state repeatedly within your lifetime (i.e. enough to generate actual usable power) should be essentially impossible.

    You should note that just the salt tax was 5% of the tax income in India (see here )

    While it isn't where I first read about it (which was so many years ago I'd be hard pressed to remember), you might try reading this summary of the writings of Arundhati Roy; in particular:

    Roy has unkind words for people who treat nonviolence as political theater. They may indeed appeal to the conscience of the oppressors and seek to win hearts by self-suffering; they may get attention and dramatize their views; they may go to jail or on hunger strikes. But they do not make salt. It may be, of course, that the same people who are doing "picture demonstrations" in the morning to get anti-war images onto television screens, are busy in the afternoon running a food not bombs kitchen or a collective repair shop for recycled bicycles, in other words, making salt.

    The second example Roy gives to show Gandhi's realism is the khadi based alternative economy, to which Gandhi gave most of twenty-five years of his life, when he was not in jail. Gandhi believed that the main motive that brought the British to India was to make money. He reasoned that on the day when they find that they can no longer make money, but could only lose money, they would leave. If Indians would practice, swadeshi, buying their own products, the British would lose their markets, and thus lose the main point of their presence on somebody else's subcontinent.

    Roy implies that Gandhi wannabes who identify nonviolence with passive resistance have misunderstood him. They should learn from the master and get real. As Richard Deats has pointed out Gandhi never intended any separation of nonviolence from constructive program. *Nonviolence was constructive program. Constructive program was nonviolence. Gandhi always regarded the slow violence of economic injustice as equivalent to the fast violence of war. Nonviolence was their common antidote. The principles Gandhi believed would lead to economic justice - village self-sufficiency, non-possession, voluntary poverty, trusteeship... etc.-- were for him every bit as essential to a nonviolent way of life as submitting to the lati (steel-tipped baton) blows of the police without striking back.

    As most people do, you completely misunderstand how Ghandi accomplished what he did. He got the British to leave economically. The people who got beaten and shot were the result of the British trying to enforce laws that they were passively resisting (i.e. making their own sea salt == not paying British salt taxes). Ghandi got people to stop doing the things that made the British money (paying assorted taxes, buying cloth made in British factories, etc.) to the point where it just wasn't worth it for the British to maintain their presence. And sure, some people got beaten and killed, but it was a lot fewer than would have died in a violent uprising, and a lot more effective, because it removed the politcal and economic pressure that kept the British in India.

    People who think marches and protests are how nonviolence worked in India are just confused. They were simply the method to publicize the actions that made it work, and to demonstrate that the laws in question were essentially unenforcable, when violated in large groups.

    People suffering from that same confusion are having war protests and anti-globalization protests here in the U.S. that are completely ineffective, because all they do is march up and down and say "we don't like this".
