   Replace "lane switchers" with "high frequency traders" and this debate reads just as intelligibly.

   Perfect security doesn't exist; the goal is to reduce the area of the attack surface. The class of attacks you're talking about is different than the class of attacks an out-of-process keyring protects against.

   I knew someone who had a vicious dog. Over the years, that dog attacked, sometimes seriously injuring, dozens of people and other animals. One day, the dog bit off the tip of the owner's finger, unprovoked. He was put down shortly ther

   Does the author not see the contradiction in complaining that a decent, legitimate business would accept a currency which is purportedly only used for crime?

   I gather the huge commitment you're referring to goes way beyond the pregnancy itself and extends to the actual parenting. In which case, why discriminate against moms but not dads? Why can a male founder have a kid but not a female on

   "Making good on a trade" is not the goal of a rational investor. The goal is increasing one's wealth. An SEC employee divested of an asset has no greater interest in the asset being devalued merely because ey once held the

    In the mid to late nineties, before Jobs returned, Apple stuck to polishing OS9 Correction: Apple didn't release OS 9 -- or even OS 8 -- until after Jobs returned. Perhaps you mean System 7? Actually, Apple barely made any progress

    This article, like nearly all on the topic, ignores the distinction between correlation and causality. Of course those who attend college, particularly a prestigious one, earn more. How much of this is due to college as a symptom of their c

    I was expecting John von Neumann to be listed as the inventor: The system also includes a processor for executing the computer executable instructions, and a memory for storing at least the computer executable instructions.

    In that case it's not a passive attack. If the NSA was routinely actively mutating nearly all SSL traffic to Google, I'd expect someone might have eventually noticed that the TCP segments are received with a different checksum th

    My point is simply that you can't subtract the velocities of the two planets and call that your delta V. Delta V is the amount of actual powered acceleration your rocket does, which is only very indirectly related to the differences in velo

    Most of the "velocity change" in your math is done by the Sun as heliocentric potential energy converts to kinetic energy or vice versa. The minimum energy trajectory from Earth to Mercury is about the same delta V as Earth to Mars. The pro

    Price rigidity means the costs of goods does not adapt immediately to fluctuations in money supply (e.g. employment & rent contracts take time to be renegotiated, price changes take time to ripple through the supply chain, etc.), so it'

    One super-useful bash feature is anonymous named pipes, which allows the equivalent of multiple pipe "arguments" to a single command. Instead of: echo a b c > /tmp/foo echo d e f > /tmp/bar diff /tmp/foo /tmp/bar Just do: diff <

    Most of the complexity of the human body (including its locomotive facilities) evolved well before humans existed. I think the analogy is just to put the time scales in perspective, not to equate their products.

    Selling off a portion of your investment to protect yourself from excessive risk is perfectly rational. Doing it partially as a function of the price you originally paid is not.
