  1. Re:Something is missing on How UPS Trucks Saved Millions of Dollars By Eliminating Left Turns (ndtv.com) · · Score: 1

    No, that makes no sense at all. If there are fewer trucks making the same deliveries, then each truck makes more deliveries, and hence travels further. Since the routing algorithm is specifically optimizing no left turns at the cost of distance traveled, the distance would lengthen, not shorten.

    Obviously, there's a confounding factor here. That could be moving to a better algorithm that reduces distance even as it optimizes for right turns at the cost of distance. However, that means that the gasoline saved is not just from avoiding left turns. TFS says that "total distance covered by its 96,000 trucks was reduced by 747,000km, and 190,000 litres of fuel had been saved", so that's roughly a savings of four km per liter saved. I suspect UPS gets more than four kilometers per liter on its trucks (a top-of-the-head conversion suggests about ten miles per gallon), and if so the amount of gas per mile has gone down.

    You cannot breed two animals together or cross pollinate two plants and get arbitrary genes that weren't there to begin with.

    So, are you a Creationist or a Lamarckist? Evolution, as outlined by Darwin and confirmed and filled in by a very large number of smart and hard-working people, is based on having mutations create variations from the original that are then subject to natural selection. I suppose you could believe in what Creationists split off as micro-evolution because they can't admit that they're flat wrong, but changing species will require new genes.

    50 years ago your doctor would hand you a pack of cigarettes because they were still selling the idea they were safe

    It was about 50 years ago that Mad Magazine printed a long jingle on how bad cigarettes were for you to be sung to a tune from a cigarette commercial. Due to a misspent life, I can still remember most of it. "Coffin nails" was slang for cigarettes. Tobacco companies were still trying to imply safety, but it was a losing cause.

  10. Back in the 60s, there was a big computer fraud case in the financial business (insurance, IIRC). It was computer fraud in that, since they had a computer, they could come up with stuff that fooled the other companies in their field who didn't have computers yet. I can't remember their name offhand, which I find annoying.

    .Anyway, they went on business spending sprees, which gave them more credibility (gee, they must be doing great to buy all that stuff for the execs) and more fun. When the company was found out, people were surprised at how little money was left.

    There's a difference between investing money with a founder who actually works to get the company going and one who is in it for the high living, and that may not be obvious on careful investigation, so I have some sympathy with the investors. I have much less for anyone who invests in his later startup.

    Not that I'm a startup founder or investor, but I'd imagine the founder doesn't want to give up control at that stage, and so the investors might be unable to stop the founder's living it up on their dime.

    A lot of the specifics in TAoCP are simply not relevant in a practical way anymore. (Disclaimer: I read the original volumes 1, 2, and 3 multiple times when I was significantly younger, and have only leafed through the volume 4 fascicles.) I can't see myself implementing a sort algorithm in C++ for anything besides amusement or exploration or something like that, when std::sort is much less typing and less error-prone. The stuff on external sorting is almost all on tape sorts. There's a long section on random numbers, and it doesn't even cover the algorithms in the C++ standard library. All the assembly language and machine code is based on MIX and MMIX, and MIX is antique. Knuth's algorithm complexity analysis is way overpicky.

    I couldn't recommend it to someone learning to program anymore. There's still a lot of good stuff in it, and someone more advanced would learn from it, but for pretty much everything it covers there's less rigorous but more useful books.

    Who agree on the general facts that we're warming up the earth by burning fossil fuels, and the results are generally going to be bad. That is a near-universal belief among climate scientists, regardless of which country they're in or how secure they are in their jobs. As for details, these are scientists, and scientists argue incessantly among themselves. It's part of research.

  18. The real world is, however, described by math.

    Much of it can be, and in those cases it works extremely well. However, you need to make sure that you're using the correct mathematical model, and that's typically not trivial. Even something well-known like gravity turned out to have a more complicated mathematical model than we thought for centuries. Econometric models don't have a really good record at predictions, and need to be verified carefully.

    Simple examples are the most obvious--such that if you do indeed have a gallon of milk, and you take half of it into another container, you can't end with more than a gallon of milk total.

    If you perform the actual experimentation with accurate and precise instrumentation, I think you'd be likely to find a slight difference. The mass will be conserved, not necessarily the volume.

    We're back where we started. If we lower the labor required, the cost goes down; at the given margin, the price comes down; to keep the price the same, costs must go up; to increase costs, we must raise wages to compensate for decreased labor; and to have inflation, we must raise wages further than that. That's a mathematical relationship.

    This is, I believe, the core of your problem. If we lower the labor required to build a widget, we lower the marginal cost. According to the law of supply and demand (which isn't a law in the sense of laws in physics), we lower the price on the widget. In a competitive market, the margin ends as about the same as before, but it may not with a monopoly. The downward pressure on price will be considerably higher in the competitive case. A monopolist can keep the price the same, missing out on some potential profit, but a competitor has to lower prices or be forced out of the market (or, if it isn't a commodity market, see market share drop). In no case will the manufacturer be compelled to raise worker pay in order to keep the marginal cost the same (the manufacturer might of course see other reasons to).

    In fact, if the new widget plant needs fewer workers to run it, that reduces the demand for labor, and according to the law of supply and demand puts downward pressure on pay.

    Back in the 1950s, industry depended very heavily on factories where lots of workers would each do one basic thing that didn't require skill. Since there was pressure to make more and more stuff, there were usually more available jobs for unskilled people willing to work hard than people to fill the jobs. This meant that a factory had to pay decent wages, or the workers would quit and go work at the factory down the road. This was the period where one guy with a job that didn't require much skill could own a small house and a fairly new used car and maybe a television, and the guy's wife stayed home, did the housework, and raised the kids. The guy would likely work most of his life at one company and retire with a modest pension. (Actual experiences would depend on skin tone, health, alcohol intake, and other factors, of course.)

    Currently, there are jobs that don't require skill, but they pay minimum wage, which is not enough to raise a family in decent style in a suburb. Median incomes haven't been going up with productivity for decades now. Empirically, you're wrong.

  19. Has the vetting process changed since 2015?

    I don't know, but there's been time to change it. I don't really know about the vetting process, except it's long and has been very successful. People keep complaining about it without telling me anything about it.

  20. You're saying nothing useful about the overturn rate of Ninth Circuit Court decisions. I don't believe the Supreme Court has heard even 86% of their cases, so this suggests that, when one of their decisions is appealed, and the Supreme Court hears the appeal, they overturn it most of the time.

    Now, I'd expect a case to be appealed primarily because one side thinks they've got a good chance on the appeal, and without checking I'd expect the Supreme Court to decide to hear cases they don't agree with, so I'd expect most Circuit Courts to have a high percentage of their decisions overturned.

    Also, there's no reason to expect Americans to be killed by people from those countries. Our screening processes have been successful so far. This has been a useful battle to pick, since it shows the US public what Trump thinks of the US courts, even if it goes nowhere.

    The people incapable of rational thought because they've been deranged by Trump are not his opponents (or, another word he used, "enemies").
