  1. This is one criticism I've had of USB. Under the guise of being user friendly, OS programmers have made the OS automatically do all sorts of stupid and insecure things when you plug something into the USB port. CD/DVD drives used to have the same problem (automatically running an executable off the disc) until it became such a common vector for malware that Microsoft finally disabled the autorun feature by default.

    When you plug in a USB device, you should get a pop-up asking if you want to access it in read-only mode or read/write mode, and whether it should be active (can auto-install stuff and mess with the system) or passive (can't change anything about your system - you will have to select/install the drivers yourself). You can have a "let the OS manage this automatically" option for the computer illiterate, but it should not be the default, and should throw up a big warning about malware vulnerability and decreased security with that option.

  4. iPhone 7 Plus has a pair of 12MP cameras that are able to take SLR-quality images. It offers bokeh capability

    Bokeh is a function of the lens diameter relative to the subject distance (and distance of other objects from the focal plane). For a given scene, cannot be created any other way other than a physically bigger lens. You know the penumbra during an eclipse (the area experiencing a partial eclipse during a solar eclipse)? That corresponds to bokeh. There is nothing you can do on the ground to enlarge this area. It is purely a function of geometry. (Mathematically, it's the point distribution function of the lens.)

    You can fake it in software. I've been saying for over a decade that two small lenses with some lateral separation should allow an algorithm to estimate distance and blur the parts of the picture outside the focal plane appropriately to simulate bokeh. But it's not real bokeh, it's a digital manipulation.

    Since at least the 1990s (when I first became aware of them). Basically the modus operandi is you found a school in some field where students can get college loans, preferably government-backed since a lot of the students aren't very credit-worthy. The students apply and are accepted into your school, pay their tuition with government or government-guaranteed student loans, and you "educate" them in the promised field. Net effect is you get the loan money, student gets the debt, and the government is on the hook for any debt the students can't pay back. You're effectively using the students to launder the money you're receiving from the government (they are listed as the recipient, not you).

    The problem is this is the exact same MO as a legit school. There are supposed to be accrediting organizations which audit the schools' programs and confirm that they are legitimately teaching students marketable skills. But some of these accrediting organizations aren't very good and should've been removed from the authorized list decades ago. Basically the same problem that led to the housing bubble - the bond credit rating agencies which were supposed to investigate mortgage-backed investments (because the average investor/student has nowhere near the resources or skill necessary for a through investigation) shirked their duties and just rubber stamped them as low-risk when they were anything but.

  11. Re:Overall a disappointing mission on Long-Lost Comet Lander Philae Found (seeker.com) · · Score: 2

    I thought the mission performed poorly too, but your criticism is off-base. The surface gravity of the comet was several hundred thousand times less than Earth gravity. It wasn't like landing on Mars. It was like docking with the International Space Station, except without a docking adapter. Landing on a planet is relatively easy in contrast because you've got a huge margin of error by which you can over-thrust and still land successfully. e.g. On Earth, basically everything between 0 and 1g upward thrust will still slow you down, yet will not compromise your landing (cause you to lift back up) after you touch down.

    When docking in zero-g or near-zero-g, you need to match velocities precisely - the margin of error is almost nil. That's why they went with the harpoon system - because docking is a damned difficult thing to do even when you have a docking adapter and a computer and human pilot right there giving real-time thrust correction inputs.

    I expected more from the mission only because the Japanese pulled off an even tougher "landing" (the asteroid was about 1/300th the mass of the comet). That spacecraft however was designed as touch-and-go, rather than permanently landing ("attaching" is probably a better word at these low surface gravities).

  13. Re:Better Programs on Finland Prepares Their First Tests Of A Universal Basic Income (futurism.com) · · Score: 3, Interesting

    It certainly would help to provide a basic income as long as people are free to work and earn extra money without loss of that basic income. There are a couple of difficulties as those that work in low paying jobs will resent people earning about what they earn without working.

    That's only an issue if you use hard cutoffs like everyone seems to nowadays because they hated math in high school and don't want anything with a formula. e.g. We'll give you $500/mo in assistance, but the moment you make more than $1000/mo working, that assistance disappears. That creates a negative income gradient. At $0 wages, you're getting $500/mo. At $1000/mo wages, you're getting $1500/mo. At $1001/mo wages, you drop back down to $1001/mo. This discourages getting a better job or working more hours. The assistance either needs to be universal (everyone receives the same amount), or graduated (using a formula!) so it's slowly phased out as you earn more so the income gradient always remains positive.

    There's also the issue where assistance scales with certain things under the control of the recipient more than the expenses. e.g. If you have 2 kids and are on food stamps, adding a third kid raises your expenses only $y/mo, but the food stamps you receive increases more than $y/mo. Thus creating an incentive for poor folks who can't afford to raise more kids to have more kids as an easy way to receive more money. The assistance has to scale in a way which discourages adding expenses, not creating more expenses as a way to get more assistance.

    Finally there's the problem where the market tries to correct for the existence of a basic income (money for doing no work) by devaluing the basic income while simultaneously increasing the value of wages (money for doing work). The net effect is inflation - the value of the currency decreases (prices increase) while wages rise to keep pace. The $500/mo basic income decreases in value year-over-year (how quickly depends on the amount of the basic income - the closer it is to the average wage, the faster it devalues), while purchasing power from wages remains steady because of the wage inflation.

    If you try to correct for this by increasing the basic income each year, you just increase the rate of inflation. If you try to fix that by fixing prices, you break the economy since production costs are now no longer allowed to be reflected in prices. So the only way to get it to work is to either limit it to a subsection of the population (i.e. it's not universal), or to make it a small fraction of the average income (i.e. it can't be a living income). You might be able to get it to work by bypassing money entirely, and distributing the basic income directly as goods and services. i.e. No more EBT cards - you get your assistance not as a money-equivalent, but as food directly from the food bank. There will be some leakage as some people e.g. sell their weekly allotment of canned foods rather than consume it, but as long as that leakage is a small fraction of the total it shouldn't have a large effect on the general economy.

  16. Self-selection sampling bias on US Would Be 28th In 'Hacking Olympics', China Would Take The Gold (infoworld.com) · · Score: 5, Insightful
    Once upon a time, a city was considering expanding its subway system. To determine if this was a worthy use of public money, they decided to find out how many hours a week the average person rode the subway. The agency tasked with collecting these statistics thought about the problem. Asking random people on the street seemed like it would waste a lot of time since most of those people might not even ride the subway. Then they realized if they just asked people riding the subway how many hours a week they rode, it would neatly filter out the non-riders and dramatically simplify their job. So that's what they did.

    When the city got the statistics, it said there needed to be 10x as many trains as they currently had. That obviously couldn't be right since the trains were only occasionally full. So what went wrong?
    • First, the statistical gathering method filtered out non-riders. This skewed the average (both mean and median) up, since they didn't have a bunch of "0 hours" in their statistics.
    • Second, asking people riding the subway gives you a time normalized sample, not a population normalized sample. Say only two people use the subway, one of whom rides it 1 hour a week, while the other rides it 10 hours a week. If you randomly hop onto the subway at any give time, you are 10x more likely to encouter the 10 hr/wk rider. Your statistics end up saying more about who is riding the subway at any given time, rather than how much each person usually rides the subway.

    Likely, the only thing these HackerRank statistics are measuring is that there are just a lot more job opportunities for mediocre programmers in the U.S. and India. While there are fewer such opportunities in China, Russia, and Poland, so the few people who pursue programming careers there tend to be the cream of the crop. To normalize it, you'd have to survey to find out how many total programmers there are in each country, compare to their total populations, then assuming a normal distribution of "skill" for the entire population of the country, map each countries results to that distribution. Then for the countries where the number of people taking the test are overrepresented relative to the total population, truncate their distribution to match that of underrepresented countries. e.g. If, say, only 0.01% of Poland's population tried the HackerRank tests, while 0.1% of the U.S. population did, then you'd have to compare Poland's results with the top 10% of the U.S. results (0.01% of the U.S. population matching the 0.01% of Poland's population) to get an apples-to-apples comparison. But that's a lot of assuming and normalizing for me to be comfortable with using the data to draw conclusions.

  18. Re:Is the design that "original"? on Legendary 747 Designer Joe Sutter Dies Age 95 (stuff.co.nz) · · Score: 3, Interesting

    They didn't set out to make a partial upper deck. The original plan was to make it a full double-decker like Airbus eventually did with the A380. But given their deadline, they didn't think they could solve the problem of adding (safe) evacuation slides for passengers on the upper deck in time, so they settled for a traditional single-decker (which they already had experience designing, just needed to scale everything up to make it wider). The short blister on top for the cockpit was added to allow the cargo variant to have a swing nose so you could load cargo through the front, instead of through the side. So it's not really "copying" someone else's design when there's only one practical solution (the impractical one being putting the cockpit in the swing-away nose and designing all sorts of latches for the mechanical linkages between the cockpit controls to the plane's control surfaces).

    This is why the upper deck on the early 747-100 is a lot shorter than in later variants like the 747-400. The few upper-deck seats on the 747-100 were an afterthought, added more for novelty than for increased passenger capacity. The lower deck on the 747 already carried nearly 3x as many passengers as any other plane operating at the time. Boeing tried for decades to sell the idea of a full double-deck 747 to the airlines, but not enough of them would commit to them. So Boeing never bothered making it. When Airbus announced their plans for the A380, Boeing tried again to pitch a full double-deck 747, and again not enough airlines said they wanted it. That's why they didn't try to compete with Airbus on the A380.

    Production of the A380 will probably soon cease, and its sales have just barely recouped its design costs. The 4-engine airliners like the 747, A340, and A380 are being eaten alive in the market by twin-engine airliners like the 777, 787, and A350 (2 engines are more efficient than 4). The disparity between A380 orders and deliveries is mostly due to airlines which placed orders but have asked to delay delivery or have refused receipt as they consider cancelling. Airbus needs to produce about 20-25 a year for the production facilities alone (i.e. excluding design costs) to operate without losing money. And right now they're scheduled to drop to 12 deliveries/year in 2018, so they'll probably wind up losing money on the A380 overall (the remaining 100 or so orders will probably be delivered at a loss, if they're not canceled outright). So it would appear Boeing's market analysis was correct that there wasn't enough market demand for a full double-deck airliner. It's a good thing the EU government guaranteed the loans Airbus took out to design the plane or this might've bankrupted the company. Competition between Airbus and Boeing is what keeps technology progressing and prices low.
