  1. The government let them do this in the first place on Visa Considers Extending 'War on Cash' Business Incentives Outside US (cnbc.com) · · Score: 4, Informative

    Good luck getting the government to try to fix this - they're the ones which made it possible. Visa/Mastercard lobbied for and got laws passed which made it illegal for merchants to add a surcharge if you pay with a credit card, to help them recoup the credit card processing fee. (That's why you see some places advertising a cash discount - it's a loophole in the law.)

    There would've been a lot more downward pressure on the 2% processing fee if merchants had been allowed to directly pass the fee on to customers. People would've preferred to pay with cash until credit card companies were able to lower the cost to something more reasonable, like a half or quarter percent. Card networks which had higher fees (e.g. Amex) would've had a tougher time than card networks with lower fees (e.g. Discover). But thanks to (corrupt) government regulation, competition to lower processing prices was eliminated, and we're all saddled with what's effectively a 2% sales tax to a private company. Even if you're paying with cash, you're paying the tax as the cash purchases basically subsidize the merchants fees for credit card purchases (since you pay the same amount for cash or credit in most stores).

    And no the fee is not for protection against fraud. The merchant pays for fraud, not the credit card company. When you spot an unauthorized charge on you bill and request a chargeback, the card processing company issues a notice to the merchant asking for proof the purchase was valid. Usually this is the signature on the credit card receipt, but for online or automated transactions this can be things like the billing address or phone number (that's why gas station pumps ask you for your zip code). If the signature or other information the merchant submits doesn't match, the transaction is determined to be fraudulent, and the processing company simply deducts the amount of the charge from the merchant's payment. The merchant is out the money and the merchandise. The only expenses the card companies have to pay for are infrastructure, equipment, and staff. With the modern Internet and computers, this is probably on the order of pennies per transaction.

    To me, those are glorified tic-tac-toe programs. They're not "thinking" about how to win at the game, they are simply exhaustively searching the solution space to find moves whose branches give them the best chance of winning. Tic-tac-toe always ends up a tie with semi-competent players because its within the capability of humans to see the entire solution space and avoid moves which result in a loss. Computers are simply able to search a much larger solution space in the same amount of time as a human.

    Humans don't play chess and go like that. The solution space in those games is too massive for them to thoroughly search, so they have to resort to a different strategy. They learn patterns and trends from repeatedly playing the game. Then they develop algorithms and heuristics based on those patterns. When they play a new game, they try to determine which pattern the current game board best approximates, and apply the appropriate algorithm to decide what their next move would be. Program a computer to learn how to play like that - without searching the solution space - then I will be impressed. e.g. What's the best chess program you can write while limiting it to, say, a thousand iterative loops for each move?

    It depends on what you're learning. For most things, forcing yourself to write it down as you're listening to it reinforces what you've just heard. Your brain has to parse the sentence, rephrase it as shorthand, then repeat that shorthand phrase to itself as it guides your hand into writing it down. That instant triplicate review of the lecture material is much better for remembering and learning than just listening. On more complex abstract topics though, the act of taking notes can distract you from concentrating on and understanding what the lecturer is saying. Likewise, on really simple topics (stuff where everything said in the lecture is "obvious" immediately after it's said), having pre-printed notes can save you from boredom. Though in that case I usually skipped the lecture, read through the notes in 1/3 to 1/4 the time I would've spent at the lecture, and did fine on the tests.

    This is why I always preferred professors who wrote and drew with chalk as they lectured - it forces them to pace themselves giving you time to either write notes, or think about and understand what they were saying. In lectures by professors who used Powerpoint slides, sometimes they'd skim over something so quickly you'd miss it and be forced to stop the lecture to ask it be repeated, or make a note to review it again after. You'd spend the rest of the class trying to remember what follows without really understanding it, so you could attempt to put the pieces together into a comprehensive whole when you reviewed your notes and the slides in your room after class (and good luck if it was the first lecture in a day packed with classes).

  7. By your reasoning, the trick Enron did (where they repeatedly "sold" an item back and forth between a subsidiary to pad their revenue) was legitimate.

    The important thing isn't the money spent. It's the value obtained from spending that money. I spend $5 on a hammer and use it to fix something that would've cost me $20 if I hired someone, then I gained $20 of productivity for the $5 purchase, for a net gain of $15. My economic productivity increased by $15. It's the productivity increase which is important, which is why the Enron trick doesn't work (no productivity was increased since they were just passing it back and forth).

    In the case of failed businesses, $x was spent but less than $x of productivity was generated. The true loss is the difference between these two, so is less than $x. But it's still a loss.

    Put slightly differently, $1.48 billion is an amount. Economic activity is a rate. Yes that $1.48 billion is still out there in different hands. But the potential for $1.48 billion of economic activity every 6 months from these businesses is now gone. (Not that this should concern anyone. $1.48 billion is less than 0.01% of U.S. GDP. Some losses are necessary when exploring the solution space of viable business activity, and 0.01% is vanishingly tiny. Bad ideas fold. The money gets re-spent on new ideas, most of which hopefully turn out to be good ideas.)

    Landfill tends to not be compacted as well as regular soil. Consequently it tends to liquefy more easily during earthquakes, leading to uneven settling and destruction of homes built on top. Nearly all the homes which collapsed during the 1989 Loma Prieta quake were in the Marina district which was built on landfill (albeit mostly from dredging the harbor). (They were also 3-4 stories, which happens to have a resonance frequency matching that of most earthquakes.)

    Smell is not an issue. The landfill is typically covered with several layers of barrier several feet thick, including watertight plastic sheeting.. Drainage holes are left along the sides to capture and treat excess water which manages to seep in when it rains, while methane recapture piping extracts gases which build up due to biological decomposition for resale. A friend's house is built on landfill and he never would've known it if I hadn't remembered the location as being a landfill from back when I was in high school.

    You can build on it, but the buildings have to be built much more sturdily than if built on regular soil, and you're still screwed if the ground settles unevenly causing the home's foundation to break. Usually the land is used for non-structural purposes, like a park.

Nearly identical to the prices you've quoted. The heat pump in your link for earth systems is cheaper than for air or water.

  11. Security theater on Airport Security Fails 17 Times Out of 18 In Minneapolis (fox9.com) · · Score: 1

    The point of airport security isn't really to thwart terrorists. It's to convince people that flying is safe, so that they'll fly instead of drive to their destination. You see, cars are much more dangerous than planes, and car accidents kill far more people than terrorists do. So a terrorist incident aboard an airliner kills more Americans by convincing them to drive instead of fly on their next trip, than it directly kills aboard the airliner. (9/11 was the exception, since the planes were used to attack another target. But as UA93 demonstrated, that's not going to happen again.)

    So the point of airport security is to convince people that the government is doing something about terrorists, and that it's safe to fly. Hence the term "security theater". Actually doing something about terrorists is less important than convincing people that something is being done and assuaging their fears about flying. Because the public's fear about flying and terrorists is irrational and completely out of proportion to the actual risk, a well-meaning lie ends up being better for society than the truth.

    Unfortunately, a lot of the people in the TSA don't get this. They take their jobs way too seriously, making air travel a hassle. This convinces people to drive instead of fly, and a good number of them end up dying in car accidents. Basically, if there are too many intrusive TSA procedures and rules, the TSA can wind up indirectly killing more people than terrorists.

Very different from when you're caught speeding and you say "but I didn't see that speed limit sign." The law says you're subject to a fine for violating it, so you still have to pay the fine even if you didn't know.

    It's like what Rambus did when they joined JEDEC (a standard-setting consortium of memory manufacturers). The JEDEC rules said members couldn't patent any ideas being discussed between them. Rambus patented SDRAM and DDR anyway, then sued the memory manufacturers for violating "their" patents. The trials found that Rambus had acted in bad faith and violated the JEDEC rules. Unfortunately those rules didn't include penalties for when a member was in violation - mainly financial penalties and being forced to give up patents obtained in violation of the rules. Consequently, the only thing JEDEC could do was kick Rambus out. The patents were still valid (the USPTO was operating under first to file back then, not first to invent). And Rambus was successfully able to extort licensing fees from all the memory manufacturers for something they themselves had invented and that Rambus had stolen.

    I'm not even sure establishing a Constitutional right to photograph/video police helps, unless you can establish a pattern of violation. Otherwise, all it's good for is forcing them to drop charges.

    The drop in oil prices has everything to do with the current political mess in Venezuela. When oil prices went up over $100/bbl, they used the extra revenue to increase social services. When oil prices went back down to $40/bbl, they refused to cut back on those social services. Instead, the government started printing more money to pay for those services (effectively stealing from its citizens' savings). That started a massive inflationary spiral which destroyed any semblance of stability in their economy.

    The government's attempt to fix it by freezing the exchange rate of the Bolivar (because they don't believe in market forces - that's why you see the exchange rate graph decrease in a stair-step) just led to more economic chaos as Venezuelan companies doing import/export were no longer able to get anyone to take their laughably mis-priced money. Thus their non-oil foreign trade mostly dried up as well. The bickering about the best way to solve this situation (hint: cut back on outlays for social services to match actual government revenue) is what's led to the current political mess.

    This is the playbook of what's going to happen to Middle Eastern countries which built most of their wealth on oil. Most of them are using their oil revenue to fund social services to keep the masses content while the ruling class (usually a family) does whatever the hell they want. When their oil revenue dries up, they're going to be forced to make a difficult choice between continuing those social services and suffering Venezuela's fate, or cutting them to preserve economic stability but then having to face the full wrath of the rioting masses for the first time in decades.

    Read up on a little history. The chaos in the modern Middle East stems from the dissolution of the Ottoman Empire after its defeat in the first World War.

  18. Re:Motivation on Tesla Model S Fails To Get Top IIHS Crash Rating (usatoday.com) · · Score: 5, Interesting
    The NHTSA tests were made by a bunch of people sitting in an office thinking up what might be a good way to simulate vehicle crashes to test their safety.

    The IIHS tests are made by the folks who have to pay out money for insurance claims, and are designed to weed out failure modes they are seeing in actual crashes which led them to pay out more than they were expecting. They made the driver's side overlap tests specifically because they saw it as a weakness with the NHTSA tests. The NHTSA test only covers impacts directly from the front and the side. Yet they were seeing a lot of claims from impacts where cars didn't hit head-on and the intrusion thus bypassed most or all the crash-resistance designed to satisfy the NHTSA test.
    • Driver drifts slightly over the double yellow line and hits a car in the oncoming lane.
    • Driver veers off the road and hits something (concrete, building, etc) at an angle driver's side first.

    Those are the scenarios that the IIHS test is trying to replicate. Passing the "small" version of the overlap test successfully is important because if the car can't, it may actually be better for the driver to let a greater portion of the car's front hit the oncoming vehicle/obstacle, rather than to try to avoid it and only receive a glancing blow. As the size of the impact area shrinks, the stresses on the section receiving the impact increases because there's less material absorbing the same crash energy. So the crash-resistance should be concentrated mostly along the sides, tapering off as you move inwards (perhaps increasing again towards the center). That is what this test is encouraging car designers to do. A car could be designed to let its left or right side completely shear off in a collision which misses the center of the front bumper, and still be completely NHTSA-compliant.
