    • “They offered me a chance to move to Korea to be a true Samsung executive,” Bullwinkle said. “I thought I was already a Samsung executive.”
    • This stuff is complex, but it gets easier from here: In classical computing, basic units of information are assigned values of either 1 or 0. But in quantum computing, the basic units of information, qubits, don’t have set values.
    • “In the whole field of quantum information, there are two different directions: One is quantum computing and the other is quantum communications,”
    • So far we’ve only identified a few problems that it’s really good at: crunching numbers—which sounds like an arbitrary math problem, but that’s how cryptography works—and searching databases.”
    • “Basically, what that says, is you cannot make an exact copy of an unknown quantum state.”
    • But if that data is transmitted as quantum information, the No-Cloning Theorem won’t allow a clean recording. It would come out garbled because of the every-changing value systems assigned to qubits (compared with the reliable 1s and 0s of regular bits). 
    • This principle is what makes quantum information so thorny. To understand it or control it, you have to disrupt it—but disrupt it too much and quantum information will lose its mojo.
    • This is a picture of the future that Apple is envisioning with HealthKit, one of the more interesting features of yesterday’s iOS 8 announcement.
    • However, in order for HealthKit to truly live up to its potential, a whole mess of developers will need to get on board.
    • Further, there’s a surprising lack of standards compliance across different devices and apps, and it’s not entirely clear how Apple’s HealthKit would resolve it.
    • It remains to be seen how Apple will put all of this together to paint an accurate picture of your health.
    • Doctors are not going monitor your health throughout the day and text you to have a good nights sleep, even if they can charge you extra to do so. They just don’t have the time, or the inclination, to do so. That’s reality.

    • Though law enforcement typically fights attempts to learn how stingrays work or how often they are used, a court victory by the American Civil Liberties Union (ACLU) has just unsealed Tallahassee police testimony of exactly how the 2008 cell phone hunt happened.
    • This is one of the few instances where I’m okay with stingray use. Local, targeted, not broad. Get an IMSI number based on witness testimony or other legally gathered evidence, search ONLY for that number, find that number.
    • I think they should have gotten a warrant before entering the home. However, because the warrant was granted on the basis of the Stingray, and not what was found in the home, I would be surprised if it was actually disallowed in court.
      • this search appears presumptively unreasonable
    • Verizon had already provided them with the phone’s unique IMSI identifier, which told the stingray exactly which handset to track.
    • Since the police did not have a warrant when they used the device, which was not commonly available to the public, the search was presumptively unreasonable and therefore unconstitutional.
    • When in use, stingrays force a connected phone to transmit at full power—depleting a handset’s battery faster than normal.
    • Using portable equipment, we were able to actually basically stand at every door and every window in that complex and determine, with relative certainty you know, the particular area of the apartment that that handset was emanating from,” Corbitt told the court.
    • Police then conducted a “protective sweep” of the apartment and waited while a search warrant was obtained.
    • olice did find the victim’s phone, purse, underwear, and ID card at the apartment, but was their “protective sweep” justified in the name of “exigent circumstances?”
    • At trial, the judge agreed and denied Thomas’ motion to suppress the search evidence; Thomas was eventually convicted. Late last year, however, a state appellate court overturned that conviction on the grounds that the search had been improper (though without commenting specifically on the use of a stingray). It ordered a new trial.
    • “Testimony that a cell phone could be flushed down the toilet does not meet the test [of exigent circumstances],” the District Court of Appeal for Florida, First District, found, in a two to one decision.
    • What does it do with the other devices it harvests? Does it dump the data (the cop would ignore other people once he had found the person he was interested in), does it tell them to connect elsewhere so the power drain doesn’t occur for them? Does it keep the data for later processing (this is where problems really start occurring)?
    • Still, the main issue that the ACLU has with this technology, as is the case with similar new digital surveillance tools, is that they might function more like “general warrants” than specific searches.
    • there’s an unsettled question as to whether use of these devices is like a general warrant, in that it could never be used. If there’s no way to use a stingray without sweeping up hundreds or thousands of other phones, than maybe it’s not a reasonable search.
    • At the very least, police need to go to a judge to demonstrate probable cause and get a warrant, and the judge needs to provide privacy guidelines.”
      • this needs to occur prior to the sweep.
    • “I’ve heard about stingrays attached to drones but seeing them on a typical police car (combined with being used 200 times) suggests the device is far more frequently used and deployed than we’ve known before.
    • These aren’t simple innocuous devices but really aggressive and invasive ones.”
    • am Shepard’s assertion that “words are tools of imagery in motion.”
    • I said the most hurtful word I could think of at that moment and, you know, I didn’t mean this in the sense of the word…I didn’t mean it in a homophobic way. And I think that doesn’t matter, you know? How you mean things doesn’t matter. Words have weight and meaning and the word I chose was grotesque and no one deserves to say and hear words like that.
    • My heart’s broken and I genuinely am deeply sorry to anyone who’s been affected by that term in their life. I’m sorry and I don’t deserve or expect your forgiveness, but what I’ll ask is that at home, if you’re watching this, and you’re a young person especially, if someone says something that hurts you or angers you, use me as an example of what not to do and don’t respond with hatred or anger, because you’re just adding more ugliness into the world and again, I’m just so sorry.
    • “Use me as an example of what not to do,” is practically poetry. I feel like we’re on a date and Hill is saying all the right things. Please, Jonah, keep murmuring these words of compassion and social awareness into my ears. You’re totally going to to score tonight (no homo).
