    Only if you're allowed to write an interpreter or compiler for the more powerful language in the less powerful one.

    This is what has been called the "Turing Tarpit." In a formal logical sense, all turing complete languages are equivalently powerful. But that means that punching holes in a paper tape by hand is technically as powerful as a high level language. We have high level languages so that we don't have to twiddle ones and zeroes.

    High level languages themselves differer in expressiveness. They can all accomplish the same tasks, but some languages make certain tasks a whole lot easier. For some language pairs, the only way to easily accomplish certain tasks in the less powerful language is to write what amounts to "an ad-hoc, informally-specified bug-ridden slow implementation of half of " the more powerful language.

    As a consequence, there is no "basic" or "generic" list of programming tasks. Tasks that one has become accustomed to do in many languages are a non-issue in some other languages. "Design Patterns" in some languages don't exist in certain others because the language itself makes them unnecessary (see Google's director of search quality, and AI expert Peter Norvig's treatment of the subject especially this slide)

    A site like Rosetta Code could only be useful for languages that are so similar that they essentially differ mostly in surface syntax. For languages much different than this their whole paradigms are different, and many of the tasks themselves are no longer the same.

    There is no other way to protect unpopular views. The whole purpose of tenure is to allow scientists with new or minority ideas that are outside of the scientific/political/economic orthodoxy to continue to do research in spite of the fact that their work can't get wide publication. We make them prove that they are competent by meeting the extremely high standards of the tenure review process - getting tenure is no cake walk - then we give them the freedom to follow research avenues without regard to how popular that area of research is, and without fear that unconventional avenues or conclusions will cost them their job.

    Part of the price we pay for this is that some people will be lazy. Academia as a whole feels that this is worth the risk because:
    1. The tenure review process will screen out the overwhelming majority of the lazy people - you simply can't get tenure if you're lazy - it's too damn hard.
    2. Carrying a few lazy professors is more than worth the benefit of having a faculty that is unafraid to voice the truth as they see it without fear of reprisal from administration, established researchers in their field, powerful alumni, government, etc.
    3. Knowing what work will lead to something "useful" is tantamount to being able to predict the future. The idea that one can tell in advance where important breakthroughs will come from or where they will lead is a bean counter's fantasy. Therefore we have to trust that extremely competent scientists when allowed to follow their own chosen research paths without coercion will come up with important results. It's worked for us so far.

    Bad analogy - cash is fungible - if the bank takes your cash (by failing) insurance of various sorts will give you cash that is exactly the same. If an application/data service provider takes your company's data and sells it to a competitor it is now worth much less to you.

    Data is unlike cash in that it gains value by being secret. Money doesn't become more valuable if I hide it from my competitors.

    Opting into this model requires that large organizations with millions of dollars - sometimes even their whole business model - tied up in proprietary databases trust the service provider not to sell them out when an tempting offer presents itself (bad financial quarter for the service provider, lucrative offer from one of your competitors, etc.) The existence of agreements to the contrary is bad CYA thinking - when a competitor drives you out of business any such agreement with your app/data services provider at best will get you a court judgement which they may or may not be able to pay, and that only after a long court battle.

    Finally, it also requires that you trust the service provider to provide adequate security - even if they don't act in bad faith, if they overlook something you lose in exactly the same way, only now it's due to industrial espionage.

The only reason he still speaks of i in his writings is because the notation for this particular imaginary (not real) number already exists. By his definition of nullity it should subsume i as well.

  11. Revolution in Genetics on Breakthrough In Human Genetics · · Score: 1

    I believe the reason this is a revolution in genetics is that the 98% figure for chimps and humans is now out the window. The idea, in part, is that we all vary in the number of copies of segments of our DNA - Copy Number Variants, or CNVs - and that having more or fewer copies of some nucleotide sequences result in significant phenotypic differences - for example people with more copies of one sequence might make more of a certain protein.

    The result is that we may share 98% of our genes with chimps, but apart from the 2% that is just outright different, there are undoubtedly great differences in the number of copies of the sequences in the 98% that we share. The net result is that we are undoubtedly much more than 2% different from chimps.

    To be even more pedantic, naive is properly spelled with a diaeresis. See the Wikipedia article.

    A diaeresis causes what would otherwise be a single syllable diphthong to be read as two separate syllables (e.g., na-ive rather than rhyming with "knave" or "nave"). An umlaut is the German term for a diacritical mark which looks the same as a diaeresis, but has a completely different phonetic function. An umlaut causes the pronunciation of the vowel so marked to be shifted forward in the mouth. Unlike a diaeresis, an umlaut does not cause a vowel sound to become two separate syllables.

    You bring up an interesting point. I think the best that ICANN can do is to have TLD specific conversion rules to and from Latin (an possibly other scripts). That is to say, each TLD (.es in this case) would define how it's unicode domain names would map to ascii/Latin. This way each nation could define their own domain name standard and others could enter these multi-byte characters directly or use the standard means of converting to UTF8/ascii/Latin specified by that country.

    Alternatively, each individual domain name owner could specify a second ascii/Latin domain name (just as they use now) rather than relying on a TLD specific conversion standard.

  14. Re:who wants better science coverage on slashdot? on Did Humans Get Their Big Brains From Neanderthals? · · Score: 1

    In addition there's no attempt to put this in context. For example, Northern Europeans share more genes with Northeast Asian populations than Northeast Asian Populations do with Southeast Asian populations. Why? Because more human genetic material is used to encode adaptations to climate such as extreme cold (winter conditions in Europe and Northeast Asia) than is used to encode superficial things like an epicanthic eye fold. The fact that to outward apperances Northeast Asians look like Southeast Asians actually says relatively little about how closely related they are genetically.

    Now to the gene in the article. It entered the H. sapiens population between 30 and 40k years ago. It is most prevalent in Europe. At that time Europe was in the grip of the last Ice Age. Wolf's Law tells us that cold climates should produce larger animals (since surface area increases more slowly than volume with increasing radius of a sphere for example, larger animals will lose body heat more slowly than smaller animals). Human beings lose 40% of their body heat through their heads. Larger heads are a great cold adaptation, which is most likely why Neanderthals had bigger average cranial capacities than modern humans.

    So if this gene variant is simply an adaptation to cold climates it's no great surprise that it's less prevalent in Africa where any benefits it may confer due to larger brain size are offset by increased risk of brain damage due to heat stroke - in equatorial climates keeping the brain *cool* is the problem, not keeping it warm.

    Human evolution is a complex problem in biology, genetics, geography, climate history, etc. Any change sweeping enough to have taken hold in 70% of the population would have to have conferred benefits across a huge swath of time, geography and climate. Human populations *always* interbreed. 40000 years is more than enough time for highly beneficial traits to move across whole continents several times over. The fact that it is less prevalent in Africa means that any benefits it may have either:
    A. don't apply in africa - for example, if it is merely an adaptation to cold, or
    B. are offset by *negative* consequences which are manifest in African geography, climate, etc.

    The idea that genes are "beneficial" in some absolute sense is silly. They are always adaptive or maladaptive in relation to a particular environment.

    One of the most important functions of an encyclopedia is as a canon of important knowledge. When absolutely *anything* can be a Wikipedia article, then wikipedia has surrendered this important function. In other words, the free editability of Wikipedia has made it impossible for many less well informed readers to distinguish among important knowledge, advertisements, and essentially worthless trivia. There's a reason you won't find an article on Chewbacca in mainstream encyclopedia's - because this is trivia, not part of the universal canon of important human knowledge.

    Does anybody really think that the rates of autism really doubled in this time period. Isn't it far more likely that the rate of diagnosis simply went up. What would cause parents to become aware of this unusual condition called autism? Maybe they saw a segment about it on TV?

    Isn't it simply possible that autism rates are correlated with TV watching because many americans get much of their information about the larger world by watching TV, and therefore the higher the rates of TV watching (determined in this study by looking at cable installation rates and precipitation rates - people watch more TV when it's rainy out ) mean higher rates of awareness of autism as a condition to ask your child's doctor about?
