  1. Re:Instance or class? on NHTSA Gives Green Light To Self-Driving Cars · · Score: 1

    Actually, I've seen answers to all of those questions.

    Yes, since all of these questions have already been answered, because SDCs are already on the road in many states. The only thing this NHTSA ruling does is help pave the way to private ownership of fully autonomous cars. But we already have corporations operating SDCs on public roads, and we already have private ownership of semi-autonomous cars, such as Tesla Autopilot, where the software is making decisions. So this ruling doesn't really change anything. It is just another incremental step.

    I think the problem is that people aren't distinguishing between real programming and putting lego bricks together.

    People are also failing to distinguish between real mathematicians, and those that use existing axioms and published theorems.

    Coding will only be useful as long as there is a dearth of coders.

    Is that why coders are paid so poorly where they are common, like in Silicon Valley, and NYC, and paid very well in places where they are uncommon, like rural villages in Mozambique?

    The report does mention quote another study that imply less collisions:

    TFA also contains this jewel of a quote:

    "It does also reduce their journey time because they all become a little bit more aware of people around them"

    In what alternative universe does slowing down reduce journey time?

    I could understand (but am not convinced) that the slower speed could result in less, or less severe, accidents. But when the proponents start making absurd statements like the above, their credibility is gone.

    People _should_ logically drive slower in those situations but they don't - and modern features like airbags + misc. break assist features makes some people think they can drive however they want.

    The second half of your sentence contradicts the first half. First you say that people don't drive slower when they think it is dangerous, then you say they drive faster ("however they want") if they think it is safer. If you drive faster when you think it is safe, then obviously you drive slower when you think it isn't.

    CS is good for grinding out mundane chores after you have used your math and logic to solve the problem.

    Most programming is sorting, searching, string processing, and user interfaces. Those involve little, if any, math (unless you think you need to design your own sorting algorithm). Math is needed for 3D graphics, and physical processes simulation, but even those rarely involve anything beyond first year calculus. You are never going to need to integrate the cube root of the co-secant.

  8. Re:More nation-wrecking idiocy on Are Roads Safer With No Central White Lines? · · Score: 2

    People pay more attention and drive more carefully if there are no white lines.

    They also slow down and drive more carefully when there is no seatbelt, and when the road is covered with ice. If you want to make driving more dangerous in order to make people drive more carefully, then the burden of proof should be on you to show that the net effect is positive. For seatbelts and icy roads, we know it is not: the additional care does not outweigh the additional risk. I doubt if removing markings is a net positive either.

    it does, in fact, appear to result in a natural reduction in traffic speed.

    That is not what matters. Does it result in fewer accidents? If drivers are slowing down because they sense that the conditions are less safe, then the absence of lines is just delaying people for no benefit.

    drop the silly coding classes that gives nothing ('nerds' will learn anyways, others never will), do maths!

    When I was in school, I learn calculus, and I learned programming. The programming has been about a thousand times more useful. Programming is also a better way to learn logical thinking. If your proof is wrong, you may never even know it. But if your program is wrong, it won't work. Calculus classes should spend less time on proofs, and more on things like numerical integration.

    Honda is "domestic" by most criteria. Most Honda cars sold in America, are manufactured in America, from American parts, using American labor. Also, much of their stock is owned by Americans, so the profits as well as the wages stay in America.

    That makes no sense, since CC does not specify any teaching method, only objectives.

    Most people opposed to Common Core have little idea what it actually is. Democrats tend to oppose it because they oppose anything that may lead to accountability. Republicans tend to oppose it because, although it was their idea, Obama is now for it, so that means they have to be against it.

    Could you please explain what your are talking about? I have two kids in public schools, and the math instruction is pretty much exactly what it should be. They focus on the basics, include real world applications (including "making change"), and allow smart kids to move ahead at their own pace on the computer.
