  1. the "true Scotsman" fallacy on 'YouCut' Targets National Science Foundation Budget · · Score: 3, Informative

    My dad was a protesting baby boomer. He was and is a republican. He strongly supported the Vietnam War. He strongly supported building more nuclear weapons, more bombers, more submarines, and so on. He loved Reagan's proposed defense against ICBMs.

    Yep, he'd be out there holding a sign to protest against nuclear treaties, defense cutbacks, etc. He got arrested for chopping down political signs for liberals. He would attend rallies for republicans. He did his best to support Goldwater. He wrote to congresscritters and talked to several in person. He wrote letters to the editor.

    These days he spends his time at Tea Party meetings. He's certain that Obama wasn't born in the USA, based on an admission by Obama's own grandmother.

  2. SS isn't in the black on 'YouCut' Targets National Science Foundation Budget · · Score: 1

    We have something called "social security benefits" and something else called "social security tax". Despite the similar-sounding names and date of origin, they are in no way related.

    Taxes are taxes, and money is money. There is no sense in imagining distinct pools of money. We can use income tax to pay social security benefits, and social security tax to pay for the military. Arguably, we do! Every dollar is like every other, so how could you possibly say that we don't? You can't!

    We can add a driver footwell camera to resolve "unintended acceleration" claims.

    We can add a view from near to passenger side sun visor toward the driver. This would document drowsy and distracted drivers.

    We could use the GPS to report people who don't signal.

    We could offer a button to report a bad driver. Something like wireless MAC sniffing would allow police to know which records to look at.

    The most stable people should get subsidized handguns, then taxed if they refuse to carry them.

    "most stable" means:

  10. but that's a violation too! on Graduate Students Being Warned Away From Leaked Cables · · Score: 1

    If you have a security clearance, you are not allowed to talk about classified materials, even if you only know of those materials from an out of channel source (the news).

    So now you're at a party, and everybody except you is discussing wikileaks. You have your fingers stuck in your ears. Oops, you just confirmed that the materials are really classified!

  11. FPGA users already don't care on Intel Launches Atom CPU With Integrated FPGA · · Score: 1

    If you care about power, you make an ASIC. An FPGA is all about being cheap and getting to market. FPGAs burn power and don't even clock fast.

  12. Knuth considered senile on ARM Readies Cores For 64-Bit Computing · · Score: 1

    He's ignoring at least two benefits that help no matter the architecture.

    First, address space allocation is a hashing problem. Calls to malloc (mmap) need to find free space; this gets slow as the address space fills up.

    Second, we care about security and we realize that programs may have bugs. ASLR benefits greatly from extra address space. This can be the difference between an attacker having a 1-in-256 chance or having about a 1-in-trillion chance.

    He's also focusing on the cache-related downside while ignoring the cache-related upside. Unless you get rid of all 64-bit libraries, adding 32-bit stuff to the system will double the amount of code that the CPU has to cache. Context switching between 64-bit and 32-bit software causes one or the other to start getting thrown out of the cache.

  13. not popular, just needy on Sex Drugs and Texting · · Score: 3, Insightful

    If you are texting all day long, you're aching for attention. That doesn't mean you are popular. Probably the opposite is true, at least in your own mind. You're begging for attention, for confirmation that others give a damn about you.

  15. 5 + 10 * 100 on How Much Math Do We Really Need? · · Score: 1

    On a stack-based calculator, you should get 100.

    When you press "+", you get a stack underflow error. Continuing on as if nothing had happened, you enter the "10". When you press "*" you get another stack underflow error. Continuing on as if nothing had happened, you enter the "100". That just sits there. (you are supposed to do "100 ENTER 10 * 5 +" instead)

    Getting 1500 would be really defective. Are such calculators actually sold?

  16. proof of engineer shortage on How Much Math Do We Really Need? · · Score: 1

    The median pay for an engineer is above the median pay for a worker. Therefore, we have a shortage of engineers.

    That proof is legitimate for any field that doesn't involve bidding wars for superstars and/or a fixed number of positions. It's wrong for things like pro sports, but it works perfectly well for anything normal.

  17. everybody will have as many kids as they can on How Much Math Do We Really Need? · · Score: 2, Insightful

    It seems your education didn't provide much about evolution.

    Those who prioritize "issues facing our planet" over reproduction are severely selected against. If family size is even slightly inheritable, we'll be back to huge families in no time. Family size shrunk because of changes in the environment (primarily birth control) but it can go right back to being large. There are existing individuals who have mental traits that encourage large family size. In not very many generations, they will become predominant.

    Squalor is the norm for all life forms, humans included.

  18. not a problem on How Much Math Do We Really Need? · · Score: 1

    It's not that everyone will learn differential equations. You don't finish high school unless you do.

    Those who can't do math don't graduate. I expect them to drop out or continue on for another year, though I admit it would be more cool to have them go on stage at the graduation and perform sepuku when their name is called.

  19. mbox needs a fix on How Not To Design a Protocol · · Score: 1

    If a line starting with "From " is changed to start with ">From ", then one must also change ">From " to ">>From " and so on. Without this, mail gets mangled.

    When reading mail, that transform must be undone. Note that even in cases where mail was stored without ">From " being changed to ">>From " it is likely less destructive to do unescaping than not. This is because humans seldom send email containing lines that start with ">From " but frequently send emails with lines starting with "From ".

  20. clearly not: prices are chaotic, fractal, etc. on LSE Breaks World Record In Trade Speed With Linux · · Score: 5, Insightful

    Prices are discrete, quantized, non-differentiable, etc.

    Prices are chaotic and somewhat fractal.

    Going faster does not solve this. Think of sign(sin(1/x)) as x approaches zero; it changes rapidly but this doesn't make it smooth.

    Hourly trades would be reasonable. You get a few minutes to submit secret bids, the exchange gets nearly a half hour to match them up, the exchange gets a few minutes to publish results, and you get nearly a half hour to decide on your next bid.

    There is no reason that the finances of normal corporations and normal investors should be subjected to the abuse of today's stock market.

  21. the procedure is ridiculous on NASA Releases Failure Report On Outback Crash · · Score: 1

    If the launch protocol includes "some dude will chase after the balloon with an ungainly hacked-up truck" then something is fucked up. The report never even comments on this!

    For extra badness: instead of putting the launch dude in the driver seat and giving him a launch button, you have him standing on a platform that blocks the driver's view. He tries to control the truck by shouting orders to the driver while the truck drives over rough ground. Assuming he doesn't fall out and get run over, he is supposed to yank on a cable when he gets the gut feeling that things are about right.

    How about this: Put a cable on the drop-away collar that is just below the filled portion of the balloon, and another on the bottom of the payload. Play out enough of the upper cable to get the balloon to a 45-degree angle. Play out just a bit of the other cable, letting the payload rise 10 to 30 feet up. Signal the collar to cut loose, dropping safely apart from the payload. Let the baloon rise until it is as vertical as the wind will allow. Play out more of the remaining cable as required to avoid a pendulum-style crash. Eliminate tension on the remaining cable (via clutch/brake) to avoid a jolt; the payload will begin rising rapidly. Signal that cable to be cut loose from the payload.

  22. still wastefull on Badgers Digging Up Ancient Human Remains · · Score: 1

    Cremation requires a huge amount of fuel.

    I suggest making biodiesel, pet food, and fertilizer.

    We could auction off the corpses for such purposes.
    Imagine them stacked on pallets with plastic straps to
    keep them from falling off and a plastic wrap to keep
    the arms and legs in. Corpse bundles would be rated
    according to estimated meat, fat, and leftover content.

    Buyers would get a chance to request individual
    auction for corpses that they find to be particularly
    desirable. Among other things, this would allow
    museums to acquire famous people for public display.

  23. Re:of course the brain has changed on What Tech Should Be In a Fifth-Grade Classroom? · · Score: 1

    You are blindly making the assumption that use / non-use of birth control is a direct result of an inherited trait that controls brain development. All of the stats out there say that it strongly correlates with education

  24. Re:of course the brain has changed on What Tech Should Be In a Fifth-Grade Classroom? · · Score: 1

    You are missing something here, either math or biology.

    Math: one group produces less than 2 children per woman. That group is going extinct if the death rate is anything worse than "immortal". The other group merely needs to manage greater than two surviving children per woman; this isn't difficult. Actually the second group need not even manage that well if we count "last to become extinct" as an evolutionary win.

    Biology: social mobility has little to do with this. Mental attributes (sexual desire, long-term thinking, intelligence, sociability...) are significantly inheritable. Children may have different attributes from their parents because the parents pass on some subset of their own attributes; what you see as social mobility of similar people between different groups can in fact be the result of people being truly different.

    Evolution is only slow when the selection pressure is minor. Remember that this isn't a matter of some gradual or mild environmental change.

    This is more like a dog breeder starting with a bunch of mixed-up mutts and only keeping the dogs with reddish hair. It takes hardly a generation or two before nearly all dogs have reddish hair. (or most any other trait one cares to select for: floppy ears, really mean, short, etc.)

    Remember the Russian experiment breeding friendly foxes, friendly rats, and hostile rats. (a story here on Slashdot perhaps a year ago) It took very little time to deeply change behavior.
