    I think you might be missing his point. Jury selection is not a random sampling, nor is it supposed to be. That jury is supposed to be representative, and it was not.

    I think what he meant was "what is the chance that two professional lawyers in a high profile case could go through voir dire and produce a jury this likely to cause later racially toned misapprehension?"

    The prosecution should have ensured at least one man, at least one black person, and at least one person from that neighborhood on the jury. The defense should have had at least one man and at least one white person. As much as most Americans (I myself am one) will react poorly to that as if it's a form of discriminatory deck stacking, that's actually how the system is supposed to work; these are the people who, in the decision making process, are supposed to bring germane context to the proceeding. This is why jury nullification is ever a topic in America - in a "queer bashing" there should be a gay person there to explain to the others what it's like to be in the victim's shoes, etc.

  4. Re:A so-called "Hydrogen Economy" is petroleum fue on No, the Tesla Model S Doesn't Pollute More Than an SUV · · Score: 1

    Hydrogen is not a power source, it's an energy storage medium.

    I have never liked this line of argument. After all, it's essentially true of gasoline, too; it's just that nature did the work. (And, in a lot of cases, the hydrogen is mined too; yay natural gas.) Both are chemicals which are oxidized to release heat energy. If the meaningful difference is whether nature or we did the work, then they're both storage media.

    You go on to cite energy capacity differences; those are only meaningful in apples to apples comparisons.

    Any line of reasoning that assumes hydrogen is a power source - rather than just a storage medium with very poor energy density - is unfortunately based on a flawed premise.

    I don't think this is actually correct.

    Where do you find the actual meaningful difference to be? It's apparently not in that they're both exothermic chemistry based on the same element.

    Other power sources aren't even remotely similar - eg nuclear, wind.

    Why are two things that are virtually identical being seen as distinct? Is the issue whether nature put the power in instead of us? Is the difference between a power source and an energy storage medium found solely in whether you primarily imagine our having to put energy in to make them viable?

    Does gasoline become an energy storage medium, despite zero actual changes, when they start sourcing it from CO2 in the atmosphere?

    What is the meaningful net effect of being in one category or the other? You seem to be suggesting that the problem isn't just the energy density (and that in itself is misleading in many ways,) but rather a more sophisticated issue of whether it's a source or a medium - and that that is what's undermining their thought.

    You can get hydrogen out of the ground, and you can spend energy to manufacture gasoline from the air, both today. If they're both sourced that way, does that mean that the lines of reasoning you're whargarbling at without actually showing an error, merely stating that there is one, suddenly become more ratified?

    What if it happened to cost as much energy to get gasoline out of the ground as is received by burning it? That isn't the case today, but someday it will be, unless we stop using it. On that day, will it have become an energy storage medium?

    Is the line about whether we have to invest energy to derive energy from it? Because calling something an energy storage medium based on how much power it takes to acquire seems ridiculous to me, as much so as does classing one chemical exothermic with nuclear and wind but against another chemical exothermic based on production rate, but I can't see any definition that seperates the two that doesn't end up with that apparent nonsense result.

    Why is it that so many hydrogen cars and busses are actually doing well, if it's such a flawed premise?

    Why are you measuring energy per liter? Liter is a unit of volume. The amount of energy per liter here is a direct function of pressure. No mention is made of pressure in two of the three cases.

    Cryogenically stored? Room temperature? The temperature of the hydrogen or gasoline has virtually nothing to do with the amount of energy released by burning it.

    Where did you get these numbers? They don't agree with the ones on Wikipedia. Granted, I'm a Wikipedia skeptic; if you can cite a valid source I'm happy to take it, but I remain somewhat doubtful that you'll be able to.

    en.wikipedia.org/wiki/Energy_density

    The proper measure here is not the energy density; that is and always has been asinine. The proper measure here is the specific energy - that is, by weight, not by volume. Hydrogen doesn't become a better fuel (oh sorry, "energy storage medium,") just because you put it under pressure. That's ridiculous. What matters is how much energy you can carry by weight, allowing for a practical limit on storage size. Hydrogen as a whole is not meaningfully better as

    Oh, Dell? You're fucked.

    They've walked away from valid warrantees on me twice now, once when I had a tape recording of the employee on tech support instructing me to do something obviously wrong - on a high price machine still under base warranty which had also had an extended warranty purchased - and promising he'd make sure it was handled if it destroyed the machine as I said it was going to.

    Why? Because their service company "Quixstar" or whatever decided they didn't feel like it, and Dell decided that meant they were off the hook.

    I've talked various employers, many already heavy Dell customers, out of buying hundreds of servers since. I expect that walking away from that $2000 laptop has cost them something like $300,000 by now, and I'm not done.

Two months later, they called me (during Hurricane Sandy, despite that they had my address and knew perfectly well I couldn't answer questions,) to see if I still wanted my replacement (!) and would I give them their RMA number (!!) so that they could finally get around to it.

    I told him my power was out and that I would love to have what they had promised me months ago, but I couldn't give him the RMA number at that time. He said he'd call back in a couple days. (Still not sure why he didn't just mail the drive.)

    I haven't heard from him since, despite having left several messages with a suspiciously similar sounding "other" staff member who assures me that *this* time I'll get a call back.
