  1. Re:Here it is for 5c on NIH Spends $400K To Figure Out Why Men Don't Like Condoms · · Score: 4, Insightful

    OK, but in this scenario (repeated intercourse without barrier), the circumcision (reduces risk by 50%) won't help either. Let p be the baseline probability of infection; let n be the # of times of intercourse. The probability of being clean afterward with circumcision is (1-(0.5*p))^n which is approximately equal to (1-p)^n for any n larger than 10 or so. Seriously, plug in values for p and plot the two curves against n.

    Circumcision "gives you" about something on the order of 10 "free fucks" before your risk catches up; but at the point it catches up you basically have a very low chance (<<5%) of being clean anyway, so... yeah, not a viable strategy for an individual. It might be effective in an epidemic model, where lowering the transmission rate even slightly can change the graph topology, which is what the research is toward.

    In short: possibly effective at treating entire populations which don't understand/accomodate safe sex; absolutely bollocks at helping an individual in a developed country.

    Turing made substantial contribution to statistics in the course of his work: http://en.wikipedia.org/wiki/Good-Turing.

    The wikipedia article is kind of dry but the problem is at its simplest: after visiting an alien planet for X days and observing n species at times t1, t2,..., tn, to estimate the number of unseen species. You can make it more difficult by adding a regression-model, i.e. assuming that species are easier to find in proportion to their mass or another characteristic.

    It's easy to imagine applying this to search the key-space in cryptography, but people actually use it for ecology (species) and genetics (estimate the number of functional variants) too. It has also been used to inform authorship statistics by allowing an "unknown"/unclassifiable category of authors.

    No cheat code, but you could save; change the difficulty level mid-game; and load. It forces you to admit failure, as opposed to sleaze your way through; but you can save face by choosing a lesser handicap. Setting it to Kindergarten difficulty basically is cheating; going down to Normal is more acceptable.

  6. Re:iirc on Wolfram Alpha Rekindles Campus Math Tool Debate · · Score: 1

    I was basing that on what my calculus teacher told me; that Newton called it "Leibniz' Rule" as a sort of mocking joke.

    However, it would appear Leibniz did correct his mistake, after ten days. He did make the mistake at first but maybe it was just one of carelessness (see these websites and their citations if needed: http://www.math.tamu.edu/~dallen/history/calc1/calc1.html; http://www.math.usma.edu/people/rickey/hm/CalcNotes/ProductRule.pdf).

    At any rate, I maintain that it's definitely possible to be able to compute integrals and not understand the concepts; as it is possible to understand the concepts and not be able to compute (difficult) integrals. After all, no practitioner living today computes integrals the same way as Newton did, except perhaps as an esoteric exercise. Computation is a skill which is partially orthogonal to understanding.

  7. Re:iirc on Wolfram Alpha Rekindles Campus Math Tool Debate · · Score: 1

    I'd say Leibniz understood the concept pretty damned well,having co-discovered it.

    And, yet, he fucked up the product rule for derivatives, claiming that (fg)'=f'g', which of course implies that he fucked up integration-by-parts (if he'd even gotten that far). Newton mocked him mercilessly for this. Some people just can't compute.

    I suspect that the median monthly payment is much smaller, and that there's a "long tail" of people-who-would-be-called-irrational-by-economists, who see the game as a social venue and thus are chipping in a lot. I used to play Kingdom of Loathing, and some of the hard core users seemed to be spending upward of $100 a month on the game partly because they spent a lot of their social time in the game and meta-game (forums; auctions; clan dungeons; &c.). They seemed to be getting a whole lot more out of it than I was and I was very impressed at the tight-knit community. Anyway, I just chipped in $10 after my first ascension and shortly thereafter lost interest entirely.

    Or, the (hypothetical) gene for suicide is, directly or as part of a mediatory network, related to positive traits such as intelligence; creativity; or even, somewhat paradoxically, long-term planning (which would help overall, but every so often you get a false negative and ...). Or, suicidality is the recessive of a gene which is beneficial when co-dominant. There are many explanations which don't require altruism or the so-called "extended phenotype".

    Fair enough.
