  1. Re:not-so-good? on Mixed Outcome of Texas Textbook Vote · · Score: 1

    There exists no law that children can't go to a private Christian school that doesn't teach evolution. In many states, the same government will pay for that in the form of vouchers.

    That's a technically accurate way of stating that which completely distorts reality. Some (as in ~10) states have small local programs, generally at the county or city level (so they don't cover the whole state). I think at best you can say there are a dozen or so pilot programs around the nation.

    The vast majority of Americans pay taxes to send their (or someone else's) kids to government-run schools and have no choice in the matter, other than to additionally pay to send their own kids to private schools. Go figure - most folks can't afford to pay double tuition for their kids.

    As far as I am aware, there are only two ways elements transmute in nature:

    1.a) Inside a normal star, fusing merrily from hydrogen on up to iron 2.b) Inside super-nova, still a matter of stellar fusion but this is how we get anything heavier than lead. 3. Radioactive decay, heavier elements decaying into stabler lighter elements, no star required.

    There's also:

    • fission bombs, though this is arguably just the same as your #3 radioactive decay
    • fusion bombs, which are genuine fusion
    • fusion reactors (tokamaks, etc.)

    I don't know if particle accelerators qualify.

    Finally, there was also the Big Bang and perhaps someday the Big Crunch.

    Except they haven't actually had the results validated... They've produced something that looks like neutron tracks, and had an expert go "yeah, that looks like neutron tracks", but that's a long way from "is confirmed to be neutron tracks". This announcement sounds dangerously like P&F's - in that they found signs in a specific test setup, but didn't vary the setup. That they seem to have found neutrons with one very specific detection method, but don't appear to have tried any other detection methods raises huge red flags.

    Bravo. I myself was wondering what controls had been run. As I recall, P&F didn't run any, which would have saved them some grief.

    I know one of the guys who helped debunk the thing way back when, and there's so much disgust for the original guys that it seems to be a foregone conclusion that cold fusion can never work. For example, in the current article, the tone seems to be that people really want to prove these guys wrong, which to me seems too much of an almost religious zeal. Worse, a lot of very prominent scientists have very vocally declared the thing impossible, and it will be a very hard thing for a lot of them to even consider the possibility that they were wrong.

    Extraordinary claims require extraordinary proof. Claiming you've discovered cold fusion is like saying you've disproved the Pythagorean Theorum.

    Let's not forget the history here:

    • Scientists working outside their field (no, don't quote Kuhn here) claimed to discover something incredible.
    • They announced these claims via press conference, instead of via the normal scientific channels.
    • Their work could not be replicated by physicists (or electrochemists, for that matter).
    • They refused to help others replicate their work.
    • Their work violated a great deal of established theory and they themselves presented no coherent theory.
    • Very quickly, the scientific community dismissed them as a bunch of buffoons.
    • Small groups on the fringe continued to believe in cold fusion with a religious zeal (a belief rather than science).
    • Said small groups continued to have conferences, publish books, etc. but never facing the rigor of the normal scientific process.

    Someone comes along now and says "hey, I've discovered cold fusion!" I'm not surprised he's greeted with derision. Cold fusion is nonsense. There is no rational reason to think it exists. There is no theory that explains it. If I told you I can snap my fingers and transmute water into gold, would you want to see my experimental results?

    In this case, the proponent refers to "the cold fusion community". Ha! The only "community" is a bunch of fringe believers working outside the norms of science. Seriously, why would he call it a "cold fusion effect"? Unless he's seeking to be endorsed by that group...

    Another question...why was this presented at the American Chemical Society? Perhaps because they can't get on the agenda of the American Physical Society? Gee, I wonder why not. This is a rerun of Pons/Fleischmann: "We are not physicists and have an experimental result that is anomalous and would overturn decades of established, fundamental physics. We have no coherent theory that fits any established model. Can we present a paper?"

    I'm sorry, but you don't know what you're talking about. All banks pay FDIC premiums. No one has lost any money (under the limit of $200K or whatever it is) in an FDIC-insured bank. Ever.

    FYI, credit unions pay NCUA premiums, which is a similar program. There are pros and cons of a credit union and for some it's a good choice, but being scared that your bank is going to fail and you're going to lose your FDIC-insured deposits is not one of them.

    Regardless of what any contract says, regardless of who actually owes what, screenplay writers are the major breadwinners yet get paid virtually nothing for their efforts. Nobody got rich writing scripts, but many many rich actors and movie moguls got rich from bloody good stories.

    Your overall point is valid, however there are a few people who sell multimillion-dollar scripts. Every now and then you read about someone hitting it big. You're absolutely right, though, that even "hitting it big" in those cases probably means earning less than the main actors.

    The reason movies suck, 95 times out of 100, is a bad script. Good writing with bad acting still often produces a good movie. The reverse is never true.

  19. Textbook Case of Small Business Failure on The Realities of Selling On Apple's App Store · · Score: 5, Informative

    The biggest lesson learned in all of this is to not spend $32,000 developing an iPhone game.

    Dapple took me about 6 months to make and had a budget of roughly $32,000 USD. That budget includes: paying my contractors, business expenses incurred during the 6 months of development, and paying myself a very small salary (akin to what I made as a junior front-end programmer when I first started in the industry).

    That's nuts. What did he think - he's launching an entire business around an iPhone color-matching game??? What is this "paying myself a small salary" nonsense? What "business expenses"?

    For this sort of thing, you do most of the dev work yourself or you partner with someone. You keep your day job and the only "business expenses" you should have are a domain somewhere.

    His costs are insane for this kind of project. They should be a tenth of what he incurred. Even at that, he'd have to sell 1,000 units or so to break even. And saying "to break even" speaks volumes about his business naivete. It's not about breaking even. You could have taken that $32,000, put it in the bank at 5%, and made $800 in six months. Instead, you made less than that and now you don't have the $32,000 any more.. He's not comparing opportunity costs.

    Honestly, I would not invest much hard money in such a venture - perhaps if I was doing iPhone dev during the day, I'd work on something on the side at night, or if I had a friend/partner who wanted to team up.

    That is far from the case these days and also worth noting that Japan was not wiped off the map and was already preparing to surrender.
