    When someone produces a non-cloud device, buy that. Sending your data back to a company for central processing is ALWAYS going to be subject to irresistible sponsorship temptation.

  2. If your AI can't figure out it's way around silly processor errors you've got a problem. Deep learning likes noise. You add extra, on purpose.

    Regular algorithms are fragile and usually don't work if the numbers don't add up. But be fair: Intel has had two real bugs that I remember, in the last... forty years? Outside of those two, I doubt anyone has even contemplated the need to patch their processor. Not many projects in the computer business can say that.

  3. Yes. I suspect that the article is either using the term cold shock incorrectly, or is using a term correctly from a different context. Cold shock is due to sudden immersion in cold water. That doesn't happen to sharks. But sharks are basically cold blooded, so if they find themselves in water that's colder than they're used to, perhaps because they swam into shallow water close to shore in a cold snap, they may find themselves too cold to swim away.

  4. Re:so on It's So Cold Outside That Sharks Are Actually Freezing to Death (vice.com) · · Score: 3, Informative

    If you fall in the water with a PFD on, you take a breath of water and are to confused to do anything productive for half a minute or so. During that time, your PFD brings you to the surface, and after that you're very unhappy, but probably alive, and quite likely near your boat.

    If you don't have a PFD on, you go further underwater, take a breath of water, and are confused for half a minute or so. During that time if you manage to actually swim, it's very unlikely it's towards the surface. In the meantime, you're breathing water like a madman. Welcome to the afterlife. Cold shock doesn't kill you: it makes you unable to prevent yourself from drowning.

    The Canadian and US coast guards did a bunch of experiments with volunteers (and proper medical and dive support) in moderately cold water. Even though the volunteers knew they were going to hit cold water, so a lot of the shock was reduced, the results were pretty dramatic. Since then, both coast guards have added the concept of cold shock to boating safety and certification courses in addition to hypothermia.

  5. Cold shock is different than hypothermia. Hypothermia is when your core body temperature drops below normal. Like the opposite of a fever. Cold shock happens when you're suddenly exposed to cold water. You have a physiological reaction that involves confusion, muscle spasms and a sudden intake of breath. It's actually what usually kills people who fall into cold water without a lifejacket or PFD.

    I don't think that's really what's happening here though, or maybe the marine biologists use the term differently. Sharks are also (basically) cold blooded, so hypothermia doesn't really apply. It seems likely the sharks are just getting sluggish in cold water and can't swim away from the shore. When they wash up the freeze (instead of suffocating).

    Someone refusing to sell doesn't determine the price, someone willing to buy (or sell) does. If bitcoin devolves to the point where nobody who's got it is willing to sell, then it's really dead.

    That seems like a particularly silly idea. The registry is only meaningful if there's a strong enough central government. If there is, you might as well just have a secure server. Have two (or ten) independent ones that integrity check each other if you're worried about them being hacked.

    Of course US insurance companies pay for unproven treatments. They may delist coverage for treatments that are proven to be ineffective, although there's huge momentum there too. And there's always the fudge factor. Even greedy US insurance companies pay for lots of antibiotics for otherwise healthy people who get colds and annoy their physicians until they prescribe them.

    Yeah, about that.

    The medical community only decided that doing randomized controlled trials (i.e. scientific ones) was necessary in the very late 80s. There was a LOT of resistance to that idea (what the hell do statisticians know about medicine?). Things take a while to ramp up, work the bugs out, etc. So treatments that were approved prior to the 90s-2010s (depending on how cynical you are) haven't necessarily been tested very well.

    Even then, some drug or procedure might be evaluated as generally safe, and effective in a particular situation. The manufacturer can't officially advertise it's use in other situations, but individual physicians have a great deal of freedom to use it "off-label".

    Stenting is a good example. It opens arteries right? And the problem is a clogged artery right? So a stent should fix it! Except that we repeatedly find, both in general and with stents in particular, that it's not that simple. A large clinical trial in the 2000s showed that intracranial stenting for stroke was ineffective, and this more recent one showing it doesn't work in stable angina.

  12. Re: Why our patent system is broken on Can Docker Survive Google? (bloomberg.com) · · Score: 1

    Yes, that's kind of cool, but it's not really a Docker innovation either. It's built on deployment scripts, like puppet or chef (or bash...) and union filesystems which go back to Plan 9 in the 80s and were first implemented in Linux in the early 90s. Docker uses one of several open source implementations.

    Docker has done a nice job of pulling a bunch of stuff together and wrapping it up in a nice package. To me it looks like they've done extraordinarily well for that. I don't really see that there's any sort of obligation to protect them from competitors who come along and do the same thing.

    You might. National postal services are often expensive to run because they have a mandate to offer comparable service everywhere, not just on profitable runs.

    I guess you don't live somewhere it gets cold.

    The most common use of fahrenheit I hear is along the lines of "it's in the 80s today." Very rarely does someone seem to give (or care about) a fahrenheit temperature to the degree, which suggests that the smaller degree size is mostly wasted.
