• Interesting simplicity in a sheepdog's herding technique

    Posted in Everything on Aug 30, 2014

    The interesting simplicity inherent in a sheepdog's movements:

    The research group outfitted a herd of 46 three-year-old female merino sheep with small backpacks containing GPS transmitters. The sheepdog was also given a GPS tracker. For each trial, the dog was simply verbally instructed to move the sheep to the gate of a 12 acre field. Then, using data from the GPS trackers, the researchers derived a mathematical model describing the rules governing the movement of both the computerized sheep and a computerized shepherd. What they found was that sheepdogs use just two simple rules: when the sh...

  • NASA melds vacuum tube tech with silicon to fill the terahertz gap | Ars Technica

    Posted in Everything on Jun 26, 2014

    This is one of the coolest things I have seen in a long time. I think the moment of transformation from digital to analog, or vice versa, is a fascinating moment to understand philosophically and practically. Here is the invention of vacuum tube technology at the nano scale. Fun not only for the advantage of extremely high frequency processing, but for the advantage of a2d transformation at nanoscale.

  • Inception is no longer just a cool fictional idea -- it's now actually possible

    Posted in Everything on May 11, 2014

    Rarely does the mind get blown by something which is literally capable of blowing the mind. This qualifies: Researchers have been able to induce lucid dreaming at will with gamma waves. Even in this initial article, they're already talking about using this technique to hack the psyche. Check it out:

    Voss and her colleagues therefore asked, if gamma waves occur naturally during lucid dreaming, what would happen if they induced a current with the same frequency as gamma waves in dreaming brains? When they did, via electrodes on the scalp in a technique called transcranial alternating current sti...

  • Neonicotinoid - Wikipedia, the free encyclopedia

    Posted in Everything on May 07, 2014

    Mode of action: Neonicotinoids, like nicotine, bind to nicotinic acetylcholine receptors of a cell and triggers a response by that cell. In mammals, nicotinic acetylcholine receptors are located in cells of both the central and peripheral nervous systems. In insects these receptors are limited to cells of the CNS. While low to moderate activation of these receptors causes nervous stimulation, high levels overstimulate and block the receptors. This receptor blockage causes paralysis and death. Nicotinic acetylcholine receptors are normally activated by the neurotransmitter acetylcholine. Normal...

  • Hands on with the OnePlus One Cyanogenmod phone | Ars Technica

    Posted in Everything on May 01, 2014

    Finally. Here's the first phone I've ever wanted to buy. A nice review of it by Ars Technica:

    http://arstechnica.com/gadgets/2014/04/flying-the-custom-flag-hands-on-with-the-oneplus-one-cyanogenmod-phone/

    Stereo recording and tri-microphone noise cancelling technology are incorporated directly into the OnePlus One. Three microphones work together to identify, isolate and enhance your voice, while simultaneously filtering background noise. Use of the third microphone increases voice clarity by up to 80%.

  • You can't parse HTML with regex (funny)

    Developer humor here:

    You can't parse [X]HTML with regex. Because HTML can't be parsed by regex. Regex is not a tool that can be used to correctly parse HTML. As I have answered in HTML-and-regex questions here so many times before, the use of regex will not allow you to consume HTML...

  • What Happens to Your Brain on Sugar, Explained by Science - PolicyMic

    Posted in Everything on Apr 24, 2014

    Notice that the normal brain has a lot more red stuff highlighted in it — called Dopamine. This chemical is produced in the part of the brain that is associated with reward. When someone experiences a reward — say while eating a really good meal — their Dopamine (red stuff) level spikes. For addicts, the opposite is true: That spike in Dopamine only comes in anticipation of the reward, as opposed to the actual reward itself. Later, once the reward is gotten, the effects are blunted because the brain has been flooded with dopamine as it thought about eating.

  • Researchers discover a new layer of happiness

    Posted in Everything on Apr 19, 2014

    Instead of dampening neuron firing found with stress-induced depression, researchers demonstrated for the first time that further activating these neurons opens a new avenue to mimic and promote natural resilience. The findings were so surprising that the research team thinks it may lead to novel targets for naturally acting antidepressants.

  • Yes, Net Neutrality Is A Solution To An Existing Problem | Techdirt

    Posted in Everything on Apr 15, 2014

    There are many concrete examples of network neutrality violations around the world. These network neutrality violations include ISPs blocking websites and applications, ISPs discriminating in favor of some applications and against others, and ISPs charging arbitrary tolls on technology companies. We have seen network neutrality violations all over the world.

  • Goldman Sachs Steals Open Source, Jails Coder

    Posted in Everything on Apr 13, 2014

    The whole article is fascinating for any software engineer to read, as it is obvious to any developer familiar with how open source software operates that this man was entirely innocent. And yet...

    the only Goldman Sachs employee arrested by the FBI in the aftermath of a financial crisis Goldman had done so much to fuel was the employee Goldman asked the FBI to arrest.

    Sad ending to the story:

    In the court of U.S. public opinion, he wasn’t well suited to defend himself, and so, on the advice of his attorney, he didn’t. He kept his long silence even after he was sentenced, without the possibili...
