    What all is required to convert ac to dc? I thought all you needed was 4 resistors in the right arrangement.

    it isn't inefficient and it isn't dirty either. the only problem is one needs a huge cap.

    Without that huge capacitor, it's as dirty as it gets. And isn't the efficiency determined by the diode voltage drop?

  2. How do you feel about dogmatic atheists? on Ask Richard Dawkins About Evolution, Religion, and Science Education · · Score: 1

    I'm a theist who reads and enjoys your books. You've often made the point that different religions can have different faults, and criticisms that apply to (for instance) Christianity are not globally applicable to all religions. I believe you've even said that religions like my own (pantheism, essential monist, science-based variety) are in your view completely unnecessary, but not inherently evil or even provably wrong.

    Yet many of your most fervent admirers approach atheism with the same faith-based, dogmatic belief as a medieval inquisitor's belief in Christianity... they invoke your name like the Pope's, and treat the non-existence of any form of deity (no matter how defined) as an article of holy writ, which cannot be gainsayed. They honestly have less open minds than most Protestants I know; they invariably start from a conclusion and proceed to redefine other people's words until they have convinced themselves they've "proved" that theists are all equally evil and that "religion poisons everything".

    I was very impressed by your recommendation that the British Humanist Association use the word "probably" in their bus billboards, just as you use "almost certainly" in many of your own statements. That, to me, shows you are a scientist and a skeptic at heart, who has not blinded himself to the possibility of new evidence simply because it's unlikely.

    How do you feel about being The Annointed Prophet of people who appear to be completely misunderstanding the problem of unreasoning faith, and the mental discipline required for the scientific method? Does it peeve you, or is it an acceptable burden under the circumstances?

    I've seen every drive in a purchase batch fail within a single week. Expensive server-grade drives, too.

    So, we mix our drives in RAID arrays. This is more important with larger drives and RAID5 (which I no longer use personally but others here still do) since in the time it takes to rebuild a RAID5, if you lose another disk or two you're sunk.

    My thought on buying them separately is that you run the risk of getting devices with different firmware levels or other manufacturer revisions which would be less than ideal when raided together.

    That's not exactly hard to check or manage, honestly.

    We replace systems (disks included) when the 4 year warranty expires.

    That explains a lot; you'll almost never see these kinds of problems. Most drives either fail in the first couple of weeks or they last past the warranty.

    You're projecting on to others, at least in my case. I don't think the way you seem to, in two-sided confrontational memes; I am a registered Republican who frequently votes Libertarian or Green Party.

    You claim I started with "oil is evil" as an axiom. This is patently false. If anything, I love oil. I use it every day. And that's why, like Nikola Tesla said around 1915, I don't want short-sighted idiots to burn it up. When I occasionally change the oil in my antique electric tractor I recycle it.

    You imply that the USA has "stabilized oil producing areas in the Middle East" which tells me that either you haven't paid any attention at all to actual oil prices (for decades) or you have a very odd definition of "stablize" which includes radicalizing generations of Muslims in the Middle East, Africa, and Indonesia, destroying dozens of major production facilities, and turning formerly lovely cities into smoking wastelands.

    See, I look at real things, not claims made by people who want to sell me stuff. If you do that, maybe some of the things that are baffling you will make sense?

    For example, go downtown and look at the price of a can of motor oil. Write it down. Now wait until after the election and check again. Then, after you do that, try and tell me that US government policies are intended to keep oil inexpensive.

    You have to be not just irrational, but willfully blind to believe that using military force to prevent Iraq, Iran and Venezuela from abandoning the petrodollar is some kind of effort to impoverish US oil producers who give billions to politicians. US government policy under Bush was essentially directed by oil companies, and Obama has certainly not made anything more than token moves against them.

  8. Both mistaken and thoroughly disproven. on Electric Car Environmental Impact: Power Source Matters · · Score: 4, Informative

    I was under the impression that the manufacturing processes to make the power plant / batteries for *POPULAR BRAND OF HYBRID VEHICLE* released the equivalent quantity of CO2 into the atmosphere as would be saved by the reduced CO2 released by the hybrid drive over it's serviceable life.

    That's neo-con disinformation, operating at several levels, that is being distributed by marketing organizations like CNW. Not only is it factually incorrect, it also implies CO2 is the most significant car exhaust pollution issue, which it certainly isn't, and ignores the fact that auto batteries are recycled (in the USA) at a rate exceeding 95%.

    There's also the issue of "service life". We all heard the stories of how buying a new Prius battery would cost more than the car, and we'd have to do it every three years - yet I have 130,000+ miles on my ten year old battery pack and it has had zero maintenance and zero problems. Other people have gone 300,000 miles with no issues. Good quality electric motors, such as the traction motors in Japanese hybrids, have a 40 year service life before rebuilding - and if the bearings are replaced at the first sign of heat or noise brushless motors can last over a hundred years. I have an 80 year old electric fan in my house (it has hand-wound coils and hand-cut steel gears in the oscillating mechanism) and it works better than modern plastic chinese-made fans - pushes more air and uses less energy, because it's extremely well made. Service life estimates based on worst-case fantasies of hybrid haters are clearly not realistic.

    The net being a loss to society, as the process for making the batteries released toxic elements not used in making regular combustion engine cars.

    Again, this is factually incorrect. Even if you accept the ridiculous definitions of pollution and service life, it's still just plain not true, and has been repeatedly debunked in peer-reviewed literature and in journals. Of course the Wall Street Journal and Fox News will keep repeating absurd anti-environment propaganda forever, but those are not reality-based news sources.

    Why is it that USA space tech prefers water splashdowns instead of dry land like the Russians and Chinese?

    IAAFRS. It's cheaper, safer, and fails more elegantly (more likely to give you a recoverable crew module that can be analyzed). Korolev might have preferred wet landings but the USSR's leadership did not trust the US Navy.

    "Softer landings" doesn't quite cut it as a reason, for at the speed of the impact, water is just as hard as terra firma.

    Nope, the capsules land very slowly, on the end of parachutes after significant braking.

    Early Soviet designs eject the pilot & flight recorder on a sled which then parachutes down. The actual capsule pancakes at fairly high speed and is completely destroyed, unlike water-landed capsules.

    Then there's the risk of crew drowning and/or craft loss thru sinking. That doesn't occur in dry land.

    Those are very real risks, but keep in mind that the capsule is a viable space environment, so pretty similar to a submarine.

    Being a brilliant business person is identifying market trends and acting on them. Which means finding out what people want and delivering it to them at prices they can afford. To do this you need to get people with the right skills together on a voluntary basis by offering them compensation that they need to agree with.

    Nope, you can torture and enslave people, extort them, kidnap their families and be widely hailed as a brilliant business person. There's really no requirement at all that participation be "voluntary". Plenty of existing businesses, and even more historically, are or were based on exploitation of workers and/or customers.

    In other words, it's up to the business person to get people together in such a way that everyone involved is benefiting and is better of than they would have been otherwise.

    No, same mistake. You're confusing "worthwhile human being" or maybe "brilliant statesman" with "brilliant business person". Have you ever heard a first person account of how Steve Jobs interacted with Andy Herzfeld? Jobs was brutally verbally abusive, and used his ability to intimidate and dominate Herzfeld to create key components of the system that enriched Jobs (and, to a much lesser extent, Herzfeld) without any consideration for how this might harm anyone. Yet everyone considers Jobs a brilliant business person!

    There are thousands more examples, from the New England slave trade to modern Chinese labor practices. I wish you were right, but you've added some things (like, basic human decency) that are not a part of this generation's definition of a brilliant business person.
