  1. Re:I call bullshit on Would You Buy the iPhone 8 If It Cost $1,200? (9to5mac.com) · · Score: 1

    Not sure why you say obscene. The iPhone margin isn't much higher than other high end smartphones, with the 7 being lower than the Note 3 and almost the same as the Pixel (https://www.techwalls.com/production-costs-of-smartphones/).

    Those "profit margins" also just compare retail cost to materials cost. They don't include R&D, certification, developing the OS, shipping, retail staff, support, warranty, disposal, etc. Considering Apple makes their own OS instead of using one offered by an analytics company, you might easily consider the iPhone margin lower than high end Android phones.

    The iPhone markup is high for a computer, similar to competing smartphones, and utterly insignificant compared to other types of luxury designer retail.

    Or you can get one in a gas station for $5. Apple seems to attract irrational hate. It's weird.

  3. Funny that you decided to look at solar after reading Slashdot. I haven't figured out whether the comments on renewable power here are shills or just Slashdot's modern ultraconservative crazy population, but most of the comments tend to be along the lines of "it ain't possible!"

    There was a story today about a report that estimates renewables will be the cheapest form of electricity virtually everywhere by... 2020 was it? It seems we're close to having innovated ourselves out of our mess, hopefully in time.

    Ah. There's no real reason why you couldn't do NIRS with a portable, or even wearable machine. You *might* even be able to do high spatial resolution NIRS with some kind of solid state array emitter like an LCD. But as you point out, I don't see cell-level polarization methods working through the skull anytime soon. I didn't directly do NIRS, but one of the animal labs had a machine. I think the useful through-skull depth in human cortex was about a mm or two.

    I would think large arrays of EEG electrodes (like hundreds of thousands) and some really sophisticated signal processing would be a more realistic (though still pretty fanciful) approach.

  5. Re:Not MRI! on Former Oculus Exec Predicts Telepathy Within 10 Years (cnet.com) · · Score: 1

    It's almost certainly near infrared spectroscopy to monitor blood flow in the cortex (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2844468/).

    MRI is mostly sensitive to water, but also to things that distort magnetic fields, such as the oxygenated and deoxygenated hemoglobin. That's the basis of functional MRI. There's no way anybody is doing meaningful functional MRI in a baseball cap any time soon though. fMRI IS the modality that the "mind reading" experiments have been done with. PET generally lacks the spatial and temporal resolution, although it can be more specific to metabolism. Neither PET nor MRI can directly image nerve activity.

    PET involves injection of radioactive tracer materials. Some of those are variations on radioactively labelled glucose, which can be used to look at metabolism. It's not likely you could make a cap sized PET scanner that could read minds, but even if you could, the radiopharmaceuticals generally have half lives in hours so you can't get too far away from a cyclotron, you'd get tired of constant injections, and you'd die of cancer if you used the thing with any regularity.

    It's all corporate BS speak.

    She's talking about using infrared to monitor changes in blood flow in the cortex. That technology currently exists: it costs sub $100,000 and usually occupies a box the size of a suitcase. So in mass production you could easily make it for $1000 in something smartphone sized.

    She is not talking about doing fMRI in something the size of a baseball cap.

  7. Re:Nuclear hate? on France Set To Ban Sale of Petrol and Diesel Vehicles By 2040 (bbc.com) · · Score: 1

    Germany produces most of it's power from non-nuclear renewables. France is aiming to produce half.

    As you say, France currently has a lot of nuclear. With expected growth in energy usage, if they're aiming to cut from 80% nukes to 50% in 20 years, that will probably mean building new nuke plants, just not as many as they'd need to do otherwise.

    It's not particularly difficult to provide most of the energy required for building a car with solar power. Much easier than actually powering the car with solar energy.

  10. Re:I wonder what's going to happen to the mid east on France Set To Ban Sale of Petrol and Diesel Vehicles By 2040 (bbc.com) · · Score: 1

    Most modern economies have very little primary (or secondary) production. The US for example. Las Vegas is a city in the middle of a desert with virtually no natural resources.

    The middle east does have a big natural resource though: land nobody cares about. That's great for solar. Some big solar plants give you lots of energy to use for things like desalination, energy intensive industry like aluminum smelting, high tech industry, etc.

    IIRC quarks stay confined in regular nuclei. The "strong force" that holds together nuclei is actually a residual force from the real strong force holding the quarks together.

    To get a quark soup, called a quark-gluon plasma, you need an accelerator.

    Quark stars have been hypothesized as a state intermediate between neutron stars and black holes, with some oddly behaving neutron stars hypothesized to actually be quark stars.

    Controlled exposure is generally part of behaviour modification treatments. You would probably structure the study in a way that is similar to how many addiction studies are done.

    For example, a colleague of mine was studying gambling addicts with MRI. So he put people in treatment for gambling addiction in a scanner and got them to play video slots. The controlled exposure was done as part of their treatment.

    For pedophiles you could give one group robots and the other none, then show them pictures of children and measure their arousal level. Or ask them. Or both.

  16. Calorie approximations are pretty approximate, but IIRC the Harvard study puts a 185 lb man (approx 80 kg I think) running 7.5 mph (about 12 km/h) at 1000 kcal/h. 90 kg can get away with a little slower. 10 km/h is pretty standard for those 10k learn to run groups, so although it's (sadly) not something the average person can just get off the couch and do, it's a long way from elite athlete status.

    I ran 10 km up a hill once with a semi-elite marathoner. She was very encouraging.

  17. Changing the port number isn't going to protect you from much. Maybe from a little traffic from casual connection attempts.

  18. Not just top athletes. A 90 kg man running at a slow to medium pace will burn around 1000 kcal/hour.

  19. It's meat, as in, muscle tissue. It's almost certainly not grown from embryonic stem cells, but rather already differentiated muscle stem cells. Also, we can tell embryonic stem cells what to become:

  21. Yeah. This is a good thing. If you're some kind of large company, or especially essential infrastructure, and some Internet thugs can hold you for ransom then it's good you find out now and fix the problem before somebody more serious comes along.

    The great thing about math is that you can work it out yourself. If you're interested, go read up on some statistics and work the probability problem of combining the results from multiple models yourself. If you want a shortcut, check out Fisher's method, or Stouffer's z-score method.
