    Human perception is hard to standardize and thus to communicate reliably (oblig: http://xkcd.com/883/); that's why scientists often recur to mechanical instruments and even those are not always required ("the specimen is alive" and "the patients reported less pain" are good enough in certain applications).

    Science is only about knowing as opposed to figuring or having an opinion. All of the scientific method tries to address the question: "can we be sure about it?"; that's its only "fundament". Everything else (blind and double-blind, sampling, error calculation, etc) are techniques to achieve that.

    It's not only about having more entropy. As the top half of the comic suggest, Joe User who is new at managing passwords may have a hard time remembering "Tr0ub4dor!", and that may lead to less security if he resorts to guessable passwords or the dreaded Post-It.

    Then comes the nasty issue of restrictions - "must be between 8 and 15 characters, with mixed case, at least one number and one symbol" (I kid you not). They're practically telling you to use 1-2 common words in l33tsp34k. There are ways around that: e.g., take the first two letters of your passphrase and "scramble" that in a compatible but consistent manner: "correcthorsebatterystaple" --> "C0h0b45t!". Don't try (too hard) to show the admin the error in his ways.

    Excerpt:

    At BGI, he says, they are currently able to sequence 6 trillion base pairs per day and have a stored database totaling 20 PB.

    The data deluge problem stems from an imbalance between the DNA sequencing technology and computer technology. According to Dr. Wang, using second-generation sequencing machines, genomes can now be mapped 50,000 times faster than just a decade ago. The technology on track to increase approximately 10-fold every 18 months. That is 5 times the rate of Moore's Law, and therein lies the problem.

    Obviously it would be impractical to upgrade one's computational infrastructure at that rate, so BGI has turned to NVIDIA GPUs to accelerate the analytics end of the workflow. The architecture of the GPU is particularly suitable for DNA data crunching, thanks to its many simple cores and its high memory bandwidth.

    Sometimes I wonder how much further ahead humanity would be if we built everything with the need to have it last decades before becoming nonfunctional, then I realize that with the rate technology has advanced, that is just not possible. Not to mention that we would have a totally different world economy if people weren't continually replacing perfectly functional items, from clothing to electronics to vehicles. So much of the global economy is dependent on people buying more things.

    Only if you don't mind your next cell phone costing you a few months' salary. Top-notch quality in tech is costly:

    The cost of the Voyager 1 and 2 missions -- including launch, mission operations from launch through the Neptune encounter and the spacecraft's nuclear batteries (provided by the Department of Energy) -- is $865 million.

  20. wrong! on Study Hints That Wi-Fi Near Testes Could Decrease Male Fertility · · Score: 1

    A microwave oven works by passing non-ionizing microwave radiation, usually at a frequency of 2.45 gigahertz (GHz)—a wavelength of 122 millimetres (4.80 in)—through the food. Microwave radiation is between common radio and infrared frequencies. Water, fat, and other substances in the food absorb energy from the microwaves in a process called dielectric heating. Many molecules (such as those of water) are electric dipoles, meaning that they have a partial positive charge at one end and a partial negative charge at the other, and therefore rotate as they try to align themselves with the alternating electric field of the microwaves. Rotating molecules hit other molecules and put them into motion, thus dispersing energy. This energy, when dispersed as molecular vibration in solids and liquids (i.e., as both potential energy and kinetic energy of atoms), is heat.
