    Too much water is bad for you, period. See also water intoxication. See, there, for all you who think alcohol is evil, you can get drunk on water, too.

    Distilled water is worse as a thirst quencher after heavy exercise because it contains no electrolytes to replenish what you lost in sweat. No big deal, as most of us get way too much salt in the rest of our diets anyway, but it is worth noting in case you are one of the three people on Earth who doesn't over-salt everything.

    As for the taste, it depends on what you're comparing it against. There's not a huge difference between well-filtered water (e.g. Aquafina) and distilled water (e.g. the grocery store jugs). There is, however, a huge difference between unfiltered or coarsely filtered water and distilled water. For example, to me, Arrowhead water tastes noticeably worse than more filtered brands, presumably because of the dissolved minerals. Other people prefer that taste. And there are many varieties that are somewhere in the middle. For example, Dasani uses filtration and then adds certain minerals back in. SmartWater distills the water and then adds salts back in. And so on. Everybody has their own preference, and as far as health goes, it makes little difference given that the vast majority of the minerals you consume come from the foods you eat rather than from the water you drink or cook foods in.

    My guess would be a separate power management controller somewhere that was wedged with everything in a powered down state. They couldn't talk to the main computer (ECU, maybe?) to reset it, which probably means that the main computer itself wasn't getting properly powered up by the power button. You wouldn't typically leave a computer system running off the car battery (even with the displays powered down) while the car is shut off. It would consume too much power.

    Either way, I agree that it probably can't have been the button itself, or else the power cycle wouldn't have fixed it. Well, I suppose it could be a self-resetting fuse somewhere, or (maybe) a stuck latching relay, but odds are, it's a power management controller or similar.

    In the grand scheme of things, this probably calls for the addition of a power management reset feature, e.g. two extra sets of switch contacts and a 555 timer IC wired up as a pulse delay circuit so that if you hold the power button down for ten seconds, the chip's power gets momentarily interrupted by a depletion-mode MOSFET. You know, something so simple that it is almost guaranteed not to fail in the lifetime of the vehicle.

    Not Redhat then? Nor Canonical? Nor SuSE?

    Nope. RedHat, Canonical, and SuSE all basically bundle open source software together. Sure, they have developers on staff, but they produce a single or maybe very low double digit percentage of the work that goes into the product. They create packaging tools, installers, custom skins, custom admin tools, etc., and they contribute patches for other things back upstream, but the fundamental core of the OS was created by others, and is largely maintained by others.

    Compare that with a true commercial OS developer like Sun/Oracle, Apple, IBM, etc. and the difference is blindingly obvious. Those companies have developers that create most of the code that goes into their products. Sure, the commercial vendors use Open Source as add-ons in some cases (e.g. Apple bundling Apache), but those companies are almost solely responsible for the bulk of the core code in Solaris, Mac OS X, and AIX, respectively. It's not at all the same development model, and the difference has nothing to do with whether the end result is shipped as open source or as proprietary code. The key difference is whether most of their code is developed in-house, and thus on how much of their own IP they have in the code.

    To give a more graphical illustration, the Linux vendors are content to stand on the shoulders of giants. The commercial UNIX vendors prefer to kill the giants, grind up their bones to make mortar, and use that to build a stone and giant-mortar dais to stand on outside their stone and giant-mortar castle. The Linux vendors usually stand to lose little if a particular GPLed work proved to be toxic. The commercial UNIX vendors stand to lose a great deal more.

    Your post said "Open Source BSD or commercial operating system" - that implies there is a difference. Largely, there is not.

    Sure, there is. OpenSolaris isn't BSD-based. It's AT&T UNIX based. AIX, same. Heck, even Mac OS X basically conforms to AT&T at this point. There basically aren't any commercial BSDs (except maybe in the embedded space) because you can't call yourself UNIX if you conform to the BSD conventions, and all the commercial UNIX vendors want to be able to call themselves UNIX.

    There are open source BSD OSes, there are commercial OSes, and there are Linux-based OSes. These are three fundamentally different camps in terms of development methodology that sometimes overlap and sometimes have common interests. Never fool yourself into believing that any two of the camps are the same.

Parasites are living organisms in their own right and reproduce in various ways on their own. The difference has nothing to do with whether the disease kills.

    In fact, viruses that kill rapidly don't stay around in the population for very long because dead people don't generally walk around and pass the disease to other people. Pathogenicity beyond a certain point is counterproductive. Thus, although most viruses would kill in the absence of an immune system. They also wouldn't spread very far, and the ones that survived would presumably be weakened strains that were not as virulent. Thus, in the long term, you'd probably end up with a similar case fatality rate as you have with viruses now.

    I didn't say that they did. I didn't even imply that. Longer breast feeding has two benefits. First, it boosts the child's immune system. Second, it is a good indicator for how late the child will begin consuming solid food, for two reasons:

    • There is a tendency to stop breast feeding when teeth come in (correlative, but not causative).
    • Kids with teeth are more likely to eat a portion of solid foods that their parents consume.

    Admittedly, that's more correlative, not causative; the causative factor is the consumption of solid food at too young an age. Breast feeding for a longer period of time tends to stave that off due to lack of demand from the child, but it's not strict causation.

    Either way, the point was that parents who are quick to use formula instead of breast feeding are also more likely to be in a rush to get away from having to give their kids special foods, and the long term effect of this is that they end up eating foods that do contain gluten (e.g. taking a bite of their parents' burgers) at an earlier age than kids who breast feed for longer periods of time. It's not that the use of formula causes gluten sensitivity, but rather that formula is symptomatic of a societally driven rush back into the workforce that also tends to cause other poor nutritional choices for those infants, which in turn, increase the risk of gluten sensitivity. It's an indicator, not a causative factor.

The party divisions were (and to an extent, still are) largely arbitrary.

    As for the "pro-slavery" Democrats, one could reasonably argue that this was the last time in the history of our country when politicians actually represented the views of their constituents.... Not that their constituents weren't wrong, but it's hardly fair to blame the politicians for actually doing their jobs (for once)....

    And to be fair, it was never about keeping their slaves, but rather to protect states' rights to decide whether or not to allow slavery.

Humorously, even in the Civil War era, the Republicans' view on states' rights depended solely on which party held the most power in the Federal Government. When Federalists were in power, they screamed "States' Rights!" at the top of their lungs, claimed to be for a smaller (federal) government, and generally tried to impede the Federalists' progress. The moment Republicans came into power, they took as much power as they could get and no longer cared about anyone's rights. Sound familiar? It should. It still happens in both the Democratic and Republican parties today, with just as much vigor.

    And like most governmental issues today, there was a lot of money involved in the slavery debate. No surprise, again, that at least initially, the wealthy slave owners won, keeping their power, up to the point of splitting off into a separate country. It would have remained that way, were it not for somebody standing up, saying "No, this is wrong", and being willing to take the country to war to make the point.

    But in the end, they shot him for it. Who is standing up now? Certainly not the Republicans, and certainly not the Democrats. Today, the people with the money win, because everyone is looking for the next big handout and no one wants to take a bullet.

    • The effect is cumulative and tends not to cause serious problems until well after the start of breeding age.
    • It seldom would be bad enough to kill you anyway.

    Thus, it is neither a significant positive nor negative evolutionary pressure, so the percentage of expression should rise and fall almost randomly through history.

    If you want to know the actual reason for the increase in gluten and peanut allergies lately, we have a pretty good idea:

    • The human body has historically not consumed such large quantities of wheat as we do today, thanks in part to better transportation and storage.
    • In countries that have historically consumed large amounts of wheat (e.g. parts of Europe that consume wheat-based pastas), the varieties of wheat grown in those areas contain significantly less gluten than the red wheat that is popular in the United States (which I think was originally indigenous to Russia).
    • Modern society has gotten so busy that few women breast feed infants as long as they should. As a result, children are exposed to real foods at an earlier time than ever before in the history of the human race. There is evidence that children exposed to gluten, peanuts, etc. too early in life are significantly more likely to develop an allergy to them.
