    Right, but Turing was homosexual and you're not

    Just as a matter of interest, I assume you have some personal knowledge of the original poster? Because there's nothing in their post that would indicate their sexual orientation, so I'm curious how you know they aren't homosexual.

    One of the more subtle aspects of heteronormativity is the tacit assumption that everyone is heterosexual until proved otherwise, so we can safely assert anyone who is not openly out or has "I'm gay!" in their .sig is not gay, because heterosexual is the default, with all the subtle biases that that comes (which as software developers everyone here is surely aware of, having seen the effects of default-centric thinking in code.)

    Statistically, of course, the assumption of heterosexuality is sensible, but given the fact of active persecution of homosexuals, even in the developed world, much less the backward and primitive Muslim-dominated countries and places where less enlightened versions of Christianity dominate, it behooves us to be as positively inclusive as possible. More than just celebrating gay culture, we need to welcome gay individuals as a normal part of human discourse.

    "Celebration" to me suggests a special event--it should be an ingrained part of our daily lives to include homosexuals, bi and transgendered people in our language. Every time we do, we strike a blow against oppression, ignorance and hate.

    I appreciate that you may have personal knowledge of the original poster, but it struck me as odd that you'd make such a strong assertion regarding someone's sexual orientation without apparent proof.

    If you don't have prior knowledge of their orientation, perhaps you can read what I've written here and tell me what my orientation is. I've always wanted to know.

    Would you argue that from a scientific, logic point of view, homosexuality is not a flaw? I mean, if ever I saw a trait that evolution would suppress, this would be it.

    Yet homosexuality is a widely observed phenomenon.

    Ergo, either evolution is broken, or there is something going on that is more subtle and interesting than your naive notions of what is adaptive or "logical". Personally, I'm betting the latter.

    "I can't make sense of this in evolutionary terms" does not mean "This does not make sense in evolutionary terms." It most probably means, "There are things that make sense in evolutionary terms that I don't understand (yet)."

    Given the known correlation between homosexuality in male humans and birth order (men with older brothers are more likely to be homosexual) there is such a stunningly obvious evolutionary reason for it that I can't be bothered to explain it to you.

    So "socialist" ain't the scare-word up here it is in the USA, although that's helped by Canadians being generally braver and more tolerant of diversity than Americans (see our gay marriage laws, for example.)

    The difference is due to two things, I think: we have a long history of robust alternative political experimentation, so we tend to go, "Ok, another bunch of wingnuts... let's see what they have to bring to the table..." because we have lots of examples, particularly at the provincial level, of wingnuts not turning out to be any more dangerous/stupid/insane than the mainstream parties.

    On the other hand, we have no imperial ambitions, and that means we aren't afraid to be seen to try and fail. This makes us more successful, in the long run, because it gives our political and economic system more freedom to experiment. Whereas the Americans know they'll be mocked around the world if they try anything and fail, which often leads them to simply not try, except in the area of military adventurism where even failure is so terrible and terrifying that there isn't a lot of mocking going on.

    In any case, attempts by Americans to influence Canadian policy have not been notably successful even with our most neo-conservative Federal government ever, and antics like these at the town hall meeting are only going to result in conditions that make it politically impossible for the Conservatives to table legislation that is seen to kowtow to American corporate interests.

    You insist that we "think of all the unnecessary processing" that goes on, but give us no reason to believe that it is unnecessary other than, presumably, the fantasy that it can be dispensed with. Why do you believe that it can be dispensed with? The most likely case seems to me that it can be externalized, so that a computing device will interface with our neural networks and neuro-chemical systems somewhat further upstream than it does now.

    In particular, I have no idea at all what you mean by "directly interpret thoughts". What is a "thought" in this context? There is a huge amount of stuff going on in the brain at any given time, and no reason to believe that any of it can be mapped onto an isolated entity that could reasonably be labelled a "thought" by any means other than looking at the operational outputs of our conventional interfaces: our words (spoke, written, or internally recited) and actions.

    You are bringing an huge and utterly unjustified load of assumptions to your argument, and if some doesn't buy into your peculiar model of the brain, which I don't, then what you're arguing for it just silly and your conclusion that somehow externalizing the transformation from internal neuro-chemical and neuro-electrical behaviour to operational effects could "drastically speed up all sorts of information processing tasks" is entirely unjustified.

    The brain is primarily a neuro-chemical machine--the neuro-electrical aspects of it that computer people tend to focus on are a very small layer on top of the underlying neuro-chemistry. And the chemistry has time constants associated with it that are adequate for information processing using the operational inputs and outputs we have: there is no reason to believe that bypassing those systems would result in any speedup at all. Indeed, it would be evolutionarily bizarre if the brain were capable of doing much more than its current speed, because there cannot ever have been any evolutionary pressure of any kind to select for that.

    Your argument is like saying that if we put a couple of jet engines on a steam locomotive it would be able to break the speed of sound, ignoring things like the mechanical limitations of th wheels and the tracks: you're focused on one obvious limiting factor in the body/brain identity's performance, and supposing that because you can imagine the rest of the system is capable of much faster speeds that it actually is.

The methods market in software development does nothing but provide an excuse to create novel hierarchies for us to climb. None of the methods that various companies sell actually increase the speed of development (laughably called "velocity" because you really need a signed quantity if you use one of these methods as you'll be going backwards half the time). None of them increase the robustness or maintainability of the finished product.

    The only reason government-only health care might be a bad option in the US is because it would be the American government running it, and the American government is uniquely and completely dysfunctional when it comes to delivering effective domestic programmes.

    Here in Canada we have government-only health care, for all practical purposes: the Canada Health Act makes it effectively impossible to deliver health care services outside of the government system, although we are starting to see more private-care options due to long waiting lists for some procedures in some parts of the country, and the government-run courts have ruled that "access to a waiting list is not access to care."

    However, despite the undoubted issues with our system, we live longer than Americans and spend less money per capita on health care than the PUBLIC health care system in the US spends, much less the vastly inefficient and ineffective private system. And this despite being more ethnically diverse and having a much smaller, more thinly-spread population than in the US.

    So it is clearly and simply false, a flat-out contradiction of fact, to say that public-only health care necessarily sucks. To believe that is exactly equivalent to the belief that the Sun moves around the Earth. The only way anyone could believe it is as an article of faith, side-stepping all the empirical evidence to the contrary.

    I mention Canada's system here because it is the one I'm most familiar with, but their are plenty of European systems that are closer to the mixed public option system the US is talking about, and they all work at least as well as Canada's and some better. But in most cases the public aspect of the system does a good job of delivering basic care. The logically disabled will at this point for some reason always point to the few places with sucky public systems, as if "some public systems suck" in some way disproves the undoubted empirical fact that "many public systems do not suck."
