  1. Re:Your Government At Work on FTC Offput by Offsets · · Score: 4, Insightful

    I don't think that's particularly fair. The FTC doesn't have the time of the resources to chase every marketing term out there, and these definitions are horribly muddy. For example, it took many years before the government (the FDA if memory serves) could agree on a definition of organic. This wasn't due to lack of need or desire or even trying, it was because the industry just couldn't agree on it.

    "Green" marketing terms are even worse. Some would claim that nuclear power is green, while others would not. Some think paper bags are green, while others think plastic is green. Is corn-based ethanol green if the fertilizer used to grow it ends up killing off most of the Gulf of Mexico? I doubt you could nail down any of these definitions in a few months, let alone a few days.

    Finally, carbon offsets are relatively new, and problematic from a consumer perspective. It's difficult to verify that way you're paying for is being done, and almost entirely impossible to verify that someone isn't selling offset multiple times. Even if you could, you can never be quite sure that someone isn't selling you a false offset. This industry is totally ripe for fraud, and it seems reasonable for the FTC to look into it.

    Uh, exactly why would mammals have some natural resistance to these diseases such that they would survive better than the dinosaurs? Especially considering that some mammals (e.g., humans) don't have resistance to Malaria

    First of all, I'm not a paleontologist.

    But here are a couple ways that seem plausible:
    Lets assume larger animals usually have much longer life cycles. If animals accumulate parasitic infections over it's life cycle at the same rate, then the smaller mammals with their shorter life cycle would have an advantage, since they would have reproduced before they are likely to be overburdened by infection. This might also help explain why smaller dinosaurs seemed to have lived on and were able to eventually evolve into birds.

    It's also possible that mammals biology was different enough than dinosaurs that most parasites preferred to infect dinosaurs. Since dinosaur-like animals had been around much longer in greater numbers it's reasonable to assume that there are more parasites that affect dinosaurs than mammals. This doesn't help explain why some dinosaurs may have lived longer than others, though smaller dinosaurs with a shorter life cycles may have been able to evolve parasitic resistance better than the larger ones.

    Casually misremembering what you actually said is a disappointing and ugly behavior.

    Whoa whoa whoa.

    I responded to a post where you said:
    This work doesn't have one drop of emotion in it.

    and I said they want to prove:
    "an OSS toolchain is a viable solution for game design." and went on to say that I though you were missing the point of the project. Apparently you said some things in other posts (which I didn't see) that were critical of the whole idea in general, which I have plenty of respect for.

    Perhaps I should have said "_their_ OSS toolchain." I'm not some drooling OSS fanatic. I don't believe that the being OSS is a key to some sort of gaming engine nirvana. I just meant they wanted to create an OSS toolchain and prove that it could create a passable game. I thought that game designers would be interested. Apparently one is not, and I'm guessing more feel the same way. And that's OK. :)

    From my perspective in silicon design, being OSS would be useful. But really, I don't know what I'm talking about with respect to game design. I'm guessing that you do. I'm interested ins seeing what comes out of the project, but you've made good strong points on why this won't really come to anything.

    It sounds like your dealings with outside software have been very positive. That's great and somewhat surprising to me. For us $500,000 buys a crap tool with crap support and lying salesmen. I consider myself educated.

    Fair enough, I can't. It's not clear to me that that's 100% relevant. The gaming industry is becoming more and more of an industry and will likely need more outside, pre-written, pre-tested software. I'd defer to you on where things are going, but it seems likely to me.

      There are OSS tools, but they're total outdated junk. Give me a timing verification system, an DRC/LVS solution and maybe a GUI layout/schematic editor that doesn't remind me of vi. Oh yeah, and an rc extractor, which as far as I can tell doesn't exist even a little bit. You'll probably also need some sort of contemporary spice simulator, though BSIM may work for some situations (we don't even try, not sure why, I don't evaluate those tools.).

    Anyone can layout a 1990's era chip with Magic. For large modern ASICs or cpus you need real, high capacity tools that just don't exist outside vendor land.

    Those only scratch the surface of modern silicon design. Only the very largest firms (maybe top 2 or 3) can afford to roll their own everything.

    Which is, more or less the point. These guys (and I don't claim that they're not misguided, I just claim they're not irrevocably stupid) just want to create a game platform that works, is accessible to more developers and creates a consulting business around it.

    [...]
    > Since there are a pile of free graphics and audio resources out there, this game isn't breaking any ground there, either.

    You're right, but if they can provide a coherent platform that any joe schmo can download and create a decent game out of, that's kind of a nice thing isn't it? Clearly they're not breaking any new ground, but perhaps in the creation of this game they'll be able to identify and fix limitations and holes in the current set of tools and allow games to be made on the cheap.

    But hey, if you think they're lame and they're solving solved problems, that's fine, you obviously know much more about game design than I do. I just wanted to point out that the primary goal of the game wasn't to create a kickass game, but to create a decent tool set that could be borrowed and built upon. Not very exciting, but not doomed to failure either.

    From my perspective, as game design grows and external tools get used more and more (which I see as inevitable), you guys would benefit a lot from having some modern OSS tools available, because vendors suck and salesmen lie. If you think that the situation is such that you have enough good tools (modelers, engines, etc.), that are high enough quality and have access to source for a reasonable price, then I'm totally wrong. Again, I was pointing out that most of the slashdot nay-sayers were missing the point about the project.

  6. Re:Oboy. on Apricot Team Selected For Fully Open Source 3D Game · · Score: 4, Insightful

    It seems to me that you (and just about all of slashdot) are missing the point.

    I agree with you, the game is probably going to be crap. But even if they had a better than average chance of making a good game, it'd probably be crap, since most games are crap.

    From what I see, the point of this game is to demonstrate that an OSS toolchain is a viable solution for game design. If they can create a game that works mostly and has reasonable gameplay, they will have accomplished the goal. If the game is lacking in the concept department, most people who make the decision to create a game will be able to see that although the game isn't vey good, the platform seems to work well enough to use as a foundation. If it ends up being a good game, it's a total home run, since they get free publicity.

    I'm surprised that as a gaming professional, you don't see the possibilities here. I'm in the silicon design industry and if someone wanted to demonstrate chip design using OSS tools, I'd be mostly unconcerned about the final product.

        The reality is that vendor tools are a serious pain an the ass. They are usually broken and support is mostly useless. Our internal tools are not much better as far as bugs, but since we have the source, there's at least some chance of getting it working in a reasonable amount of time. If someone demonstrated the 90% of what we needed was OSS and it had some miles under it, we'd be all over it.

    That said, I'm sure they still have an uphill battle to achieve even a modest success, but I don't think it's hopeless.

  8. Re:So if I stop looking? on The Universe Damaged By Observation? · · Score: 1

    Positing that particles behave differently when being 'observed' would require you to provide a testable definition of 'observation' whic I don't think you can.

    An observation is determining the eigenstate of a system. If the system was previously in a superposition of eigenstates this will resolve into one of those possibilities. This isn't a very satisfying definition, but describes any measurement that can be made on a quantum mechanical level.

    The theory that particles behave the same whether or not they are under experimental conditions is an essential precondition for science.

    I'm not sure that this is strictly necessary for science, and we know that this isn't the case. What we're arguing about is the mechanism. If you choose to believe on faster than light interactions with no known mechanism rather than observation causing changes to particle system that's fine. For what it's worth many scientists (e.g Einstein) thought QM was an incomplete theory for this reason, but among QM physicists the latter idea is a more popular view I think.

    All QM tells us is that it is impossible to set up an experiment that measures two complimentary variables at the same time. The interaction necessary to measure one will disrupt the other. QM does not tell us that the decision to record the results of an experiment changes the outcome.

    Again we know that observation cause systems to change, we just don't agree on the mechanism. What happens When we _don't_ do an experiment, is indeed a question for philosophers.

    From http://en.wikipedia.org/wiki/Uncertainty_principle

    "The uncertainty principle in quantum mechanics is sometimes erroneously explained by claiming that the measurement of position necessarily disturbs a particle's momentum, and vice versa--i.e., that the uncertainty principle is a manifestation of the observer effect. Indeed, Heisenberg himself may have initially offered explanations which suggested this view. Prior to the more modern understanding, a measurement was often visualized as a physical disturbance inflicted directly on the measured system, being sometimes illustrated as a thought experiment called Heisenberg's microscope."

    A simple example is the z component of the spin of an electron, as measured in the Stern-Gerlach experiment (http://en.wikipedia.org/wiki/Stern%E2%80%93Gerlach_experiment). You can re-measure the z component of spin over and over again, you'll always get the same result. If you take a supsequent measurement of the x component, you'll have a 50/50 probability of getting +-1/2. If you re-measure the z component, the electron forgets its previous spin value, and you have a 50/50 chance of getting +-1/2 again. T
