  1. conveniently leave out Xerox, Apple on Microsoft Co-opts Ice Bucket Challenge Idea To Promote Coding In Latin America · · Score: 1

    I notice you conveniently left Xerox out of the Dynabook story. The project originally called "the interim Dynabook" was renamed the Alto. Xerox had done the R&D to develop Kay's idea into a working machine. Around this time, Xerox owned part of Apple, so they invited Steve Jobs and other Apple people to Xerox Parc, where they had a look at the Alto (Dynabook) development version. The Apple folks really liked the GUI idea, so they worked and worked to transform it into something that could work in the real world, made of materials that actually existed. And that's how we got the desktop GUI.

    Kay had a wish "I wish for a kid's toy that's tablet sized, with a battery that lasts forever". Xerox and Apple started with the wish and developed something doable - and completely different from Kay's original vision. Kay jad wished for a children's device, Apple and Xerox created the desktop computer GUI for adults, something nobody had asked for.

    Yeah I remember back in 1980 we were all going into the stores trying to buy ipads and 3D printers. After we consumers did the R&Dand speced out exactly what kind of iPad we wanted to buy, Apple ordered some from China and started selling them.

    Wait, maybe I'm remembering wrong. Maybe a bunch of companies hired a bunch of engineers, programmers, and product designers to come up with a variety of different computing devices, hoping that they'd come up with something people wanted to buy. Maybe people did not buy the first few tablet models, so for the first 15 years those companies were losing money trying. Maybe Maybe eventually one company, Apple, developed a version people would buy.

    I don't remember for sure, which of those two scenarios actually happened?

  3. in space, you cannot turn? on Sierra Nevada Corp. Files Legal Challenge Against NASA Commercial Contracts · · Score: 1

    > The centripetal force that is needed for any circular (or curved) movement is provided by the gravitational pull of the moon/earth, e.g. the gravitational force.

    Think about what that would imply, it would mean that it's impossible to turn in space, away from the earth's gravity. In fact, it woild mean that here on earth you could only turn downward, toward the earth. Nascar drivers couldn't turn left, because all curved movement must curve downward.

    G-force and gravity behave in indistinguishable ways, so it appears that they are the same thing (per Einstein). That does not mean that all G force is EARTH'S gravity. Orbital centripital force is gravity(-like), so it can therefore balance the gravity coming from another source (earth), resulting in net zero g aboard the spacecraft.

  4. gravity equal and opposite to centripital force on Sierra Nevada Corp. Files Legal Challenge Against NASA Commercial Contracts · · Score: 1

    I looked and found more about it. You could of course fly around the moon at an altitude of 500 meters. Orbit has a specific definition it seems - centripital force being equal and opposite to gravity, so they balance out. Anyone inside the craft therefore feels zero gravity. If gravity pushes your into your seat as the craft flies around, that's not orbit, that's flying around.

          Centripital force is small when you're moving almost in a straight line. Traveling just above the earths's surface, for example, the turn radius is several thousand miles. Therefore, for gravity to be balanced by centripital force, you need to be far enough away that gravity is reduced sufficiently that the small centripital force can balance it.

That's certainly suspect. They might not completely screw everyone who touches their code, but they've reserved the right to do so.

Why would you say today's won't be? MD5 was believed to be secure for a long time, now it's thoroughly broken. What evidence is there that SHA-3 doesn't have an undiscovered weakness, given that every other algorithm has had some?

    Further, quantum computers have now actually factored semiprimes, proving the theorems. So we already know how to break existing keys, given large quantum computers. At this stage, with so little knowledge about what medium-scale quantum computing, is it not hubris to think our kids won't come up with ways to use the new powers of quantum computing to solve problems that we don't yet know how to solve efficiently?

  12. It's not, and that wasn't actually slippery slope on Forest Service Wants To Require Permits For Photography · · Score: 1

    Slippery slope is the argument "if we let them ban filming movies, the next thing you know they'll ban all photography". The fallacious version stops there, just silently assuming that ALL slopes are slippery, rather than asserting that a particular slope is in fact slippery. The non-fallacious version points out that the number of pages of federal regulation has grown by 10,000% in the last few decades - showing that indeed the federal government DOES tend to enact more and more regulation. That slope really is slippery, and it's not fallacious to point that out.

    Also GP said the current regulation IS too broad. Lannoc didn't say "if we allow this regulation, next thing you know they'll have a regulation that is too broad". So although Lannoc actually used the words "slope" and "slippery", the argument wasn't slippery slope - he asserts that the current regulation is too broad, not that it will become too broad. He (she?) also asserts that "the slope is getting slippery", rather than implying the assumption that all slopes are slippery, which would be the fallacy.

    Quoting myself, in my national energy policy paper:

            Solar electric is another option that has received significant attention, and it has some very attractive qualities.
            Lewis and Nocera (2006) calculated that the total amount of solar energy striking the earth and it’s atmosphere

            and hourly fluctuations will occur.

    Your concept of making critical national policy decisions based on your current emotions ("hatred") is interesting.
    My post you replied to is based on the fact that I know how energy is measured. Donkey cubed is not a measure of power.
    The proponents of this project clearly have no idea what they're talking about, none at all. As I said above, they're not even
    wrong - they're unintelligible. Advocating nonsense instead of actual, workable renewable energy is how we've remained

    decades, and billions of dollars, on pump-and-dump schemes promising "free energy". Quoting Morris (2014) again: ... This media interest can also create significant public relations issues for the solar industry and solar advocates.

          In 2006 story, the chief news editor for Nature called Nanosolar “the poster child for Silicon Valley’s interest in solar power”.
          Six years later, this “poster child” announced they would soon start shipping panels, thereby gaining more media attention
          and investment (Wang 2012). Just one year later, Nanosolar closed down and was auctioning their office furniture,
          having spent $450 million of investors’ money (Wang 2012).

            Nanosolar is not the only solar company to vanish after getting hundreds of millions of dollars from hopeful investors.
            In 2011, ABC news showed FBI raids of Solyndra offices and the homes of the Solyndra founders, with the FBI seeking
            to find out what happened to over half a billion dollars in taxpayer funds which had been directed to Solyndra (Greene & Mosk, 2011).

    Do you think hyping this kind of fraud _helps_ the public perception of renewable energy?

    Based on your tolerance for absolutely sloppy work, I'm guessing you're education is limited to government school,

    In the US, and probably many other places, the original argument for strict government regulation of broadcast goes like this:

    The radio spectrum suitable for broadcast is limited (there can only ever be ~20 TV channels).
    It won't work to have multiple broadcasters competing on the same channel.
    The spectrum is a public resource.
    The public, through their bureaucrats, must choose certain broadcasters and grant them exclusive rights to a channel.
    Because the public is granting the broadcaster exclusive rights to a limited resource, they have the right to make demands in exchange.
    As representatives of the people, government has the right to make arbitrary demands of broadcasters.

    Based on that reasoning, the regulation of cable TV is much less, and of the internet far less.
    The internet is not a limited medium, there can be millions of channels, and nobody is being granted exclusive rights to anything.

    Of course the majority view in Canada is coming from an entirely different perspective. Canadian reasoning is:
    1) ???
