    Yes, but if one spends your first twenty years growing up in a New Age cult of evolution deniers, one is awfully late to the party when it comes time to buckle down with intelligence and hard work.

    When you're picking teams at the staff picnic to run the obstacle course, do you pick the kid who practically lived on a skateboard growing up, or the bookworm with coke bottle glasses? A secure sense of balance navigating logic-dominated systems takes just as much work to develop as a bunch of skateboard tricks.

    We had a kid in my residence who had never wrestled with his siblings growing up. He got the hang of it pretty quickly when the rough-housing started, but someone always got beaked in the nose whenever he was involved. The rest of us knew how to play hard without getting hurt or hurting anyone else.

    You're not born any of these things, but the differentiation is well under way by elementary school. That beaker is a doctor now.

    Correlation does not imply causation

    In the second case, you get wankers who take this maxim far too seriously, when they should be reasoning "where there's smoke, there's fire". The vast majority of valid reasoning falls below the harsh standard of implication. Programming escapes many people, because you have to have one foot in each camp. pfail = 1e-6 is no good for a file system. In debugging, the common case is to succumb to the rare event.

    I've worked with really good students who can't consistently manage to get modular clock arithmetic right on a micro-controller. In the vast majority of cases, normal algebra applies, except when it doesn't.

    /* monkey number one */
    u16 begin = clock();
    while (clock() - begin < 100);

    /* monkey number two */
    u16 begin = clock();
    while (clock() < 100 + begin);

    In a normal programming task (e.g. far away from the file system), this kind of small distinction isn't critical every hour of the day. But when it does become critical, you need the kind of person with an instinct for realizing "but wait, this might be the tricky bit, slow down a think a bit here".

    This requires an innate capacity for self-monitoring the process of conviction. Many people have it, more people don't. The second group will never become value-added programmers whether they are trained and paid a wage or not.

  3. brute force in the Slepian-Wolf social network on Passwords Not Going Away Any Time Soon · · Score: 3, Informative

    Brute force security needs to be evaluated under the assumption that a Russian botnet has compromised a large number of social networking sites, and gained three to five different clear-text passwords (of possibly no great importance) associated with the targeted user. They now also know--or strongly suspect--the identities of your financial institutions.

    Using commonalities of the exposed password set, the botnet bastards will attempt to model your personal password generation heuristic. Since they are not stupider than bricks, they might also assume that your bank password is similar, but fortified to the next level. Gaining some experience in cracking bank passwords, they'll soon have a model for that, too.

    My Thomas and Cover from 1991, which happens to be at hand, has chapters on "Jointly typical sequences", "Encoding of correlated sources", and "Source coding with side information". This last section makes reference to Slepian-Wolf encoding, which is kind of interesting. I hadn't spotted that before.

    On Slepian-Wolf compression, in memory of Jack Wolf

    Along with David Slepian, Wolf proved the Slepian-Wolf theorem: as long as certain conditions are met, files X and Y can be compressed to H(X,Y), even if the X server has no knowledge of file Y, and vice versa.

    This might not be precisely the right theory to apply to the breaking of password clusters, but the guy doing the math on that has probably read these papers.

    Way too little concern is placed on the independence of the passwords chosen, and this vulnerability increases rapidly with the proliferation of passwords used. I'm sure I have more than 100 passwords out in the wild, many held by hopelessly incompetent and untrusted internet discussion forums.

    Even a single compromised site can form a model of your password heuristic if you're duped into changing it often.

    It wouldn't surprise me that if everyone adopted the four word xkcd approach, that for many individuals, entropy per word is closer to seven or eight bits than eleven, where concrete nouns of five to eight letters predominate, and a further bias to concrete nouns that are visually active in the mind's eye, and 40% of all such passwords contain at least one animal word.

    That's where brute force would begin: assume at least one common animal word (four to five bits; since cat/dog don't make the cut, you'll be seeing a lot of parrot/leopard/zebra/unicorn).

    It used to be the case back in the 1970s that everyone watched the same horrible TV shows, and you could always ask the people you hung out with what they thought of the same show you watched yourself.

    This is the old Coke vs Pepsi common-knowledge trick. You could always bring it up in conversation because you knew that the other person would also know what you were talking about. There was no escape. The purpose was not to manufacture preference, but to perpetuate the very slight distinction between one type of brown sugar water and another as a revealing choice of personal identity. I remember reading about a study of perceived choice where a tray of different soft drinks was presented to a group in eastern Europe who complained "how come we're not being given any choice at all?" For them choice was coffee, tea, soda pop (who cares which). But in the west, five different types of sugar water was regarded as a choice cornucopia.

    I can tell the difference between Coke and Pepsi anywhere, anytime. Pepsi has lemon, Coke has vanilla. But I roll my eyes where people comment "oh, you're a coke drinker". Yeah? So what if I happen to like sharp vanilla over mushy lemon. Further into my adult years I decided sugar water was just so much junk in the trunk. The one occasion per year I drink a can of Coke, my selection of Coke over Pepsi is almost a religious experience. I'm a member of the Jonestown generation. We were programmed to care about such things.

I have a fairly clear recollection of reading a long piece about Grothendieck several years ago which lamented the loss to mathematics when he devoted the bulk of his career to elaborating a program in algebraic geometry instead of cracking one hard problem after another, which it seemed some people thought he could do. He was regarded by some as much too brilliant for the pedestrian task of assembling an overarching synthesis.

I was disappointed: it reached solution without once backtracking. I think it made three guesses in total, either binary or trinary. I vaguely recall the odds of it guessing correctly all the way to solution was about ten to one. I loaded some other hard problems. On these it actually backtracked from time to time, but not as often I would have presumed. Even hard problems fall quickly to structured guess-work.

Are we all better off driving on whichever side of the road suits us on any given day? Pretty quickly you arrive at Rawl's concept of the original position: whichever symmetry-breaking decision is made must intrinsically favour one side or the other, but the process by which the decision is reached need not. Allegations of unfairness succumb to circular argument. Success in life is a proxy for good decision making, so we choose successful decision makers (whenever the process is overt). Wealth is a common proxy for success, but also for corrupt influence. Ergo we are all dictators inside.

    If the corporate romance had happened a decade earlier, it still wouldn't prove that the design put forward required leaching off the Japanese, but it would hard enough to disprove so as not to interfere with random geysers of ideology.

    The outlines of the rent seeking story are roughly that Washington lobbyists are the heroine of profit maximization, and that it only we enact prohibition against government will the profit maximizers settle down to clean living and wealth creation to the benefit of greater society.

    My view is that after government hours after government is declared drowned in the bathtub, the profit maximizers of the drug-seeking stripe will quickly discover crack cocaine (some other way of extracting rent from society) with society shorn of collective will as weakly expressed through the government organ to oppose them. The view that modern government is grotesquely imperfect is quickly quelled by listening to 50 hours of podcasts about the Roman empire or the Byzantines who followed. These were small governments in cahoots with large armies principally concerned with rape and plunder.

    After we flush government, what power remains to cross crack cocaine off the list if it is discovered half so quick as I suspect?

    I'm of the view that there is another possible road forward: the Long Now project of evolving government to be less like heroine and more like methadone. I have dark suspicions about the prohibitionist, cold turkey no-government agenda. It might go well for a while, but when the morning arrives that it isn't going well, what are your options? Few historical precedents have glowing resumes. Too many people run around espousing the view that the blood on those documents resulted from an administrative paper cut.

    Let me be number seven: you're an idiot.

    Since when is the HDMI standard is a good reference point for arguing human perceptual limits? Furthermore, many things which are quite obvious have no supporting research. Research is like open source, except that the itch has to be even bigger to successfully fund the project. Where's the incentive for pouring research dollars into quantifying the trench between 24 fps and 60 fps? Celluloid is not getting cranked above 24 fps for mainstream productions due to cost reasons (it was tried and failed more than once), and digital playback devices are standardized at 60 Hz already, which poses hardly any cost barrier just a few years down the road. For every paper on the fundamentals of visual motion perception, Google returns a hundred patents on motion estimation and interpolation devices screaming to be monetized.

    I've read several excellent papers over the years on the trade-offs in human acoustic perception (which the margins of my generosity are too small to fish up) where the golden ears demonstrate different trade-offs between fine pitch/duration perception, but always along the same contour.

    From Judder-Induced Edge Flicker in Moving Objects

    In natural scenes, smooth pursuit stabilizes or reduces the temporal rate of motion of a moving image on the retina. Smooth pursuit of a sequence of momentarily stationary images, however, produces a geometric shearing of the image on the retina

    This paper is talking about degradation. For my purposes, if I can discriminate degradation at 30 fps vs 45 fps, then I can perceive something valuable in one that the other lacks.

    In many theatres, I find the judder so severe in a rapid pan I can almost count the frames. Back in the day, 45 fps was the break point in many games where my motion estimation starts to feel creamy enough to nail a snap spin frag. I could image a small additional improvement all the way up to 60 fps, if you're after that last one percent advantage.

    Strangely, there in an ethos is science (which I generally laud) where many researchers tune out the ridicule and devote themselves to proving the obvious nevertheless. Perhaps the definitive paper you are seeking will make the cut on next year's Duh! list.

    Guys also indicated that even with hook-ups (which are meant to be string-free), they feared their casual-sex partners would seek a relationship. Women indicated the opposite, wanting a relationship and worrying about becoming too attached to a noncommittal other. Who knew?

    Sometimes it is THAT obvious. And now, in 2011, we have a paper to cite.

    From Wikiquote:

    Russian historians have no record of the lines, "Death of one man is a tragedy. Death of a million is a statistic," commonly attributed by English-language dictionaries to Josef Stalin.

    Since we're not sure it was spoken, I guess the pendulum swings back to tragedy.

    Stalin would surely have continued: "Death of 30 million is prudence." What if it was you and your wife and your gf and your mother and your father? Hint: a day of morning is tragedy, a thousand years is history.

    Does the $120 necessarily mean that it's more likely to make it to 5 years before failing?

    That's a bit of a haughty Socratic tone to explain basic cost/benefit bereft of leverage. As soon as you add volatility to production quality, the warranty liability creates a huge incentive to shift the dubious batch into USB drive appliances at Walmart or Costco.

    Without the warranty liability, there's little incentive for the drive manufacturer to bother with the complex logistics of sorting the better grades into the usage patterns less tolerant of failure.

    And you're also forgetting how good Detroit became at building cars able to last until the day the warranty expired with hardly any buffer. I know someone who did electronics design work at a major auto components company in the Great Lakes area and was given a stiff rebuke for choosing a part that cost pennies more (our of several dollars) with double the life expectancy. If the cheaper component is already rated to the warranty period, not one penny more. It turns out this is stupid economics. Eventually the consuming public figures it out. Many fat executive bonuses were paid before America nationalized the auto industry.

    Here's what enlightenment looks like: In recent design iterations, Intel has a rule that if a feature increases the power budget by 1%, it has to increase performance by 2%.

    I think the shorter warranties are a vote by the Seagate executive team to have a business model more like Detroit, and to collect as many performance bonuses as possible, before exiting their careers as the disk industry declines to Kodak levels of relevance.

    A good dictator is better than a good democracy, because the dictator is more easily able to get things done.

    Attribution bias is a core value in religious and political alignment. On the right: belief in The man or The Man (specifically The man claiming to represent The Man). On the left: the Buddist concept of the great oneness. On the far left: git and the great maintainer. Get your own bag.

    The dictator is more able to get the kinds of things done we credit to a single man, but not much else. A Stanford leadership podcast says that in the management literature you find that a leader gets 50% of the credit or blame, but contributes only 15% to the final outcome.

    Much of the point of the invisible hand metaphor is that a lot gets done in markets where you can't easily point to any one person to assign all the credit/blame. I also recently learned that Adam Smith tossed off the phrase "invisible hand" in passing, and that his acolytes elevated it to the level of faith-based market economics.

    For many people, knowing who to blame is more important that getting things done (or the right things done), even if The man blamed is exempt from consequence, but the blamee pays with his blood and kin.

    When the Germans voted Hitler into power, they weren't looking forward into the Palantir at the mass rape of the mothers, sisters, and wives by the Russian hordes bent on retribution. No, they voted him in because of their frustration and the sense that he could get things done. A little more heed to outcome rather than credit/blame, we'd have fewer of these people around. They start small. Soon you find yourself in uniform with a man behind you instructed to shoot you if you take one step back. You hate the regime you're fighting for, but that hatred is never more than 10 seconds away from an anonymous, unmarked grave. The only question is whether it will be a solitary grave in the ditch on some dirt road, or if you'll have plenty of company among the bone fields of Stalingrad.
