  1. Re:Rail serves the medium distace market well. on High-Speed Trains in the US? · · Score: 1

    As I said, SF-LA might be a specail case where rail works well. However if two cities have airports that is not at capacity they are often better served by planes using the airport than rail.

    When there is a lot of point to point traffic over short distances rail makes sense. This does not describe most situations. Remember, the airport is free as you have to build it for your long distance travel anyway. If it is also under utilized (which may or may not be true), sending planes is the better option.

    I would have spelled it out, but I have no hope of coming up with a spelling close enough that my spell checker can find the right one. MS is well recognized as the name in general. Only on slashdot does MS commonly have a different meaning, so you can be excused for being wrong at first.

  3. Re:A Serious Reply on Automation in the Workplace? · · Score: 1

    It is correct in most cases. Automation right now can remove the tasks that any idiot can do, but the harder, more expensvie tasks are not automatable. The people who do those jobs are often people who don't have the mental ability to handle more complex job.

    Anyone (with minimal physical abilities) can place tab A into slot B all day on an assembly line. No brain power required at all. No anyone can program the robot that does it in their place, nor can most people fix that robot. Even if they could, one person can keep hundreds of robots running, and each robot replaces at least 1 person.

    There are expensive tasks, like airplane pilot that can be (and should be) automated. However most of the jobs expensive people are doing are too complex to automat.

    If you are the person who doesn't get replaced, or you are replaced, but you have the ability to do something more valuable for the company, then you are correct. However many people are not in that situation, they are replaced by the robot and not given anything else they can do.

    Linberg wasn't the first to cross the Atlantic, but most people think he was, most of those who know he wasn't (such as me) have no clue who was first.

    I once worked for a company making routers years before Cisco started, yet Cisco has convinced everyone they were first. (I don't think this was intentional on their part) That company often introduced a new technology that Cisco released about a year latter. We never went anywhere though, while Cisco made billions.

    First is interesting. It is useful for those who need it now. However first is not the jump most people think it is. Quality, price, reputation and marketing matter at least as much.

    Simple physics. Your water pressure it between 20 and 60psi. (Anything higher will break hoses) City water is generally on the high end because cities have to reach the upper floors of houses on top of hills, and regulators are a lot each to install and maintain than pumps. Well water is often on the low end because you set it for what you need.

    20 psi means that if you have a tube with a piston with one square inch of surface area, the piston will hold up 20lbs. A little math and you can find how big a piston you need to lift the weight (Not mass, we care about fighting gravity) you are concerned about. Now just place the piston in a tube long enough, and apply water. It will lift your elevator.

    The hard part is making this without digging a hold DOWN 2 stories to place your tube in. There are many solutions to this, they are left as an exercise for the reader.

    Read the FAQ. In short, the contributors will decide what to do.

    Since most of the people on this project are involved with some other java project, they can at the very lease re-license their own source code, and that might be enough to get most of the other code into the Apache license. One would presume that they also have contacts with most of the other developers, and might be able to talk them into license. That covers the legal issues.

    There is one other issue. These people have experience with one implementation. One presumes that along the way they have learned from their mistakes. They might decide to throw it all away (see mozilla) because now they know how to do it right.

    Apparently crop rotation didn't occur to anyone back then.

    It did. The founding fathers who had slaves were looking for ways to save their soil before the revolution. However cotton brings in a lot more money than any of the crops you can replace it with, so you pretty much need cotton growing (on good soil) all the time. Tough to do.

    It wasn't so bad before the cotton gin, because before then it was hard to extract the seeds from cotton so there was less profit. Once the gin was invented you needed slaves to tend the cotton fields, and you needed cotton fields to generate the money to feed the slaves year round.

  18. Re:Mathematics Out of the Closet on Mathematicians Become Hollywood Consultants · · Score: 1

    You don't need a directional antenna if you can determine (through other means) exactly when the signal arrived, and compare when each listener gets the signal. From there you draw circles on the map, where they intersect is the target. This requires at least 3 listeners (and some way to know they are all gathering the same signal), but more is better because it is hard to get clocks accurate enough. As your listeners report in you get a triangle that comes closer and closer to the transmitter.

    In general I prefer to use your method, but when directional antennas are not workable. (If your target is sending a burst once a day, so fast you can't determin direction when it arrives, then this is the only thing workable.

    Even with your method you prefer to have more than 2 listeners because if one has a problem you get errors.

    A jetski is about the least efficient boat on the water. It is a small, high power (relative to size, ships are easily 100x the power or more), and highly maneuverable craft. Their efficiency is known to be horrid. Jets[1] are less efficient than props[1], but they are more responsive. JetSkis operation on plane, which allows them to go fast, but takes a lot of power. Most jetskis (up to a couple years ago) have 2 cycle motors which run poorly outside of the powerband, meaning that even going at low speed isn't saving much fuel.

    A ship is a large, low power (relative to size!), poorly maneuverable vessel optimized for getting from point to point as cheaply as possible. Ships never operate on plane. (a boat that is not on plane has a speed limited by size, the larger the boat the faster it can go, but still not as fast as a much smaller jetski)

    Of course in theory you could build a ship and put it on plane. I think the navy has a few that qualify. Nobody else wants to spend that much fuel.

    People get a jetski to have fun with. As a purely recreational toy nobody cares about the fuel is drinks. A ship is bought for efficiency, and you deal with slow speeds. (when you are burning thousands of gallons of fuel small savings add up)

    How the rest of the world sees the US has no bearing on any facts. The facts are hard to see without a lot of history to look at, something we won't have for a few hundred years. (and that assumes the history is recorded correctly)

    Have you ever heard of economic cycles? They happen to everyone. The US has already hit the low point in the latest cycle, and is raising back up. Happens all the time. It has always been popular to think that the current position in the cycle will hold on forever, but the facts have never bore that out.

    It is n surprise the currency is also down because of the cycle. Exchange rates are tied to economy. This is a good thing, it means when you have a bad day relative to others, the others can buy more of your stuff for the same amount of money, which means they are more likely to buy from you, which will lift you back up. Once you are up and booming your currency raises, and people look for goods elsewhere, helping someone else.

    Tourism is in part a reflection of economy. Even so, tourism is just one use of spare money and time, if people suddenly decide to take up gardening in their spare time, that would hurt tourism. You have stated a fact, as if it was bad, but there is no reason to assume it is.

    The "poverty line" is defined by politicians for their advantage. People below the poverty line in the US normally make several times the average person in the world. I know people who are below the "poverty line", and their life is just fine. They don't have all the luxuries that politicians think you need to live but that doesn't mean their life is bad.
