    The thing is, most of the shit isn't from guns. CDC leading causes of death in the U.S., page 41. Skipping all the disease deaths we get:

    41,149 - suicide (21,175 of them by firearms, about 2/3 of all firearm deaths)
    38,861 - accidental poisonings and overdoses (passed traffic accidents recently)
    37,908 - (land) motor vehicle accidents (nearly 3/4 alcohol-related)
    30,208 - accidental falls (mostly among the elderly)
    16,904 - other accidents
    16,121 - homicide (11,208 by firearms)
    4,587 - Other undetermined events (281 by firearms)
    3,391 - accidental drowning
    2,768 - complications from medical and surgical care
    2,760 - accidental fire
    1,569 - water, air, space vehicle accidents
    1,000 - other land transport accidents
    516 - killings by law enforcement (usually by firearms)
    505 - accidental discharge of firearms
    15 - war

    Now, compare that list to what you see the press covering. Suicides, drug overdoses, motor vehicle deaths, falls, drownings, medical complications, are vastly underreported. Firearms (which I've put in bold), air transport accidents, killings by law enforcement, and war/terrorism deaths are vastly overreported. (IMHO fires are reported about the right amount - fires make good video).

    Roughly 2/3 of the firearm deaths are from suicide. But firearms account for roughly half of suicides. So you can make a pretty convincing argument that the people who shot themselves probably would've figured out some other way to successfully kill themselves if guns weren't available. So you shouldn't attribute these deaths on firearms.

    That leaves the 11,208 firearm homicide deaths up for debate. Which certainly is a topic worth debating. But its importance falls far behind suicide, drug overdoses, motor vehicle accidents (mostly drunk driving), falls (this one is debatable since it's mostly elderly who are killed this way), and other types of accidents. As a whole, these things are 11.7x more likely to kill you than homicide by firearm.

    In other words, firearms homicides comprise less than 8% of the shit in the shit sandwich. An objective, statistical approach to reducing the preventable non-disease death rate in this country would prioritize reducing these other causes higher than tackling firearms homicides. The overdose death rate in particular is very troubling, since it's roughly tripled in the past 15 years. This increase accounts for twice as many lives lost than would've been saved if we'd somehow managed to eliminate all firearms homicide deaths. Yet the press practically ignores this compared to firearms homicides.

    Doing business in China is a balance of how much are you willing to pay off people and how much you stand to profit. The more you want to profit, the more of that profit you need to "invest" in the Chinese legal system. The Chinese don't see it so much as bribery as the do what they tend to call it "investments". People who sell products in China, need to be vested in the unique interest of China in order to sell their wares there. Or at least that's how the logic works that I've been explained

    It's actually the same reasoning used to tax corporations in all countries, except "us" and "them" have been reversed so most people now find the concept foreign (no pun intended). The corporation is able to conduct business in the country due to its social and legal system, so it needs to "invest" in the interests of that country by paying taxes.

    It sounds like fairness when it's a corporation you don't care about (them) paying those taxes and you're the beneficiary (us). But when it's "your" corporation being forced to pay and someone you don't care about and whose legal system you have no say in (the Chinese) is the beneficiary, the same thing sounds unfair.

  3. "My money" does not exist in a vacuum. You get to live your life through the benefits of the rest of society.

    I don't think you or Rawls quite understood what money is.

    Once upon a time, people had to live on their own. They had to grow and harvest their own crops, hunt their own meat, tan and sew their own clothes, build their own shelters, make their own tools, treat their own injuries, etc. This was hugely inefficient because of the massive number of skills you needed to learn, and the rapid multi-tasking you needed to do to accomplish everything.

    Then someone came up with the idea of trade. One person would specialize in growing and harvesting crops. Another in hunting meat. Another in making clothes. Another in making tools, etc. They would then trade what they made for what other people made. Specialization meant that you only needed to learn one skill, which meant you could learn how to do it a lot better than when you had to learn dozens of skills. You could also concentrate solely on that one skill instead of constantly being interrupted to attend to something else. This increase in efficiency led to a massive increases in productivity per capita.

    You would then overproduce your specialty, and trade it with other people for the things they specialized in making. You trade your productivity for their productivity. Money was invented afterwards, to facilitate trades. If you were selling clothes but needed meat, and the guy selling meat didn't need clothes but did need tools, you would have to find someone selling tools who needed clothes in order to make the multi-way trade work. Money allows you to skip these multi-way trades - everyone just trades for one common denominator aka money. In other words, money is just a representation of productivity.

    So you do not "owe" money to society just because you made it. The fact that you made money means that you already paid society - by contributing your productivity to society's trade of marketable skills. If you hadn't contributed to society, you wouldn't have made the money in the first place. In other words, the fact that you made money means you already paid for the benefit you derived from the rest of society. It is, in fact, your money - you gave away your skills, your productivity in exchange for it. That money is a direct representation of what you worked and toiled over to create. It is your money just as much as it was your clothes before you sold them.

    The concept of taxation comes about when a society decides there are some things which should be made or done which would benefit everyone (or at least enough people that it's deemed worth doing). Roads, aquifers, a sewage system, etc. Each person then contributes a share of their earnings, their money (actually their income, which is a time flux, a first derivative of money), to pay for these things. Of course this was immediately abused by those in power like the nobility to turn taxation into a mechanism by which they could steal money from people doing productive work, so they could live in luxury without having to actually contribute any productivity of their own.

    But absent corruption, this is the idea behind taxation. How much each person should contribute has and still is debated. Should everyone have to pay the same amount? Should those who make more pay more (after all someone who runs a trade caravan gets more use out of the roads than someone who uses it only to bring a wheelbarrow of apples to sell at the market)? Once you've made enough money to pay for your own survival needs, should any extra money you make be taxed at a higher rate? Or do those who fail to make enough money to pay for their own survival simply need to find a better trade which produces something other people want enough for them to make more money?

    This is the way trademark law works. You must defend the trademark or risk losing it.

    Citibank's trademark is for a reward points program. Their beef is with an AT&T Thanks program which, like the Citibank program, rewards loyal customers. So that aspect of trademark infringement (that the two names are for a similar product or service which could be confused) is satisfied. This isn't because AT&T is just saying "Thanks" as TFS claims.

    At that point, even if Citibank thinks the lawsuit is silly, they still have to file it. Once the court decides there is no infringement, both sides are safe. AT&T is free to call their program AT&T Thanks. And Citibank's ThankYou trademark is safe because they defended it

    If they didn't file a lawsuit, someone else could start another rewards program named "Thanks" or maybe "[company_name] Thanks You." When Citibank sued them, they could point to Citibank's failure to defend their trademark against AT&T. The court could decide that that constituted Citibank abandoning the trademark.. Even though the possibility of that is extremely small, the fact that it's not zero means the trademark holder is going to play it safe and file a lawsuit against anything which could be considered a trademark violation.

    The NOx and SO2 that "clean" coal plants emit are only a small part of the pollutants. The vast majority is CO2, which is the same per kWh for both a "clean" or "dirty" coal plant.

    Since you obviously didn't read the link to my efficiency calcs, here they are again:

    An ICE engine can hit about 30% efficiency. An automatic transmission is about 90%-95% efficient (pretty impressive considering it's just squirting fluid at a turbine).

    Newer coal plants are about 40% efficient. Natural gas plants are about 60% efficient. Split the difference and go with 50%. Power lines are about 98% efficient. Real-world charging efficiency of the Tesla is about 80% (1/1.26 = 0.79). That is, 80% of the electricity from your wall socket goes into the battery, the other 20% becomes heat. I can't find any numbers for discharge efficiency, so let's call it 100% for now. And electric motor efficiency is about 90%-95%.

    Tally it up and you get:
    ICE: 30% * 92.5% = 27.8% efficient
    EV: 50% * 98% * 80% * (100%) * 92.5% = 36.3% efficient.

    If the discharge efficiency for the battery is also 80%, then the EV efficiency drops to 29%. For all intents and purposes the same as the ICE. Coal and gas plants are not "much more efficient" than ICE engines, and EVs are not "much more efficient" in using that electricity. (The EV is cheaper to operate because coal is an order of magnitude cheaper per Joule than gasoline.)

    As for the other posts saying their EV is clean because they charge it with solar panels, you're not correctly accounting for opportunity cost. That reasoning only works if you got the solar panels installed only because you got an EV. If you were a conscientious environmentalist and would've gotten the solar panels installed even if you hadn't gotten the EV, then the extra energy consumption of charging the EV has to be made up by the grid.

    State A (no panels, no EV): x kWh consumed by your home. Net power used from grid = x kWh
    State B (PV panels): x kWh consumed by your home, y kWh generated by panels. Net power used from grid = (x - y) kWh
    State C (PV panels and EV): x kWh consumed by home, z kWh consumed by EV, y kWh generated by panels. Net power used from grid = (x - y + z) kWh

    So if your starting state is A, and you get the EV plus the panels only because you got the EV, then the net change in power you take from the grid is:
    (state C) - (state A) = (x - y + z) - x = (z - y) kWh from the grid
    And you can correctly state that your panels (y kWh) are providing electricity for your car (z kWh).

    But if you were a good environmentalist and were going to get the panels even if you hadn't purchased an EV, then the net change in your power consumption from the grid is:
    (state C) - (state B) = (x - y + z) - (x - y) = z kWh from the grid
    And your EV's power consumption (z kWh) is entirely attributable to the grid, not to the panels.

    All cars result in emissions. There is no such thing as a zero emissions vehicle, at least not with our current power infrastructure. We've just created a legal framework where blame for the environmental harm from generating the energy the EV uses falls upon the coal and gas plants which generate most of that electricity, instead of on the driver using the EV.

    You can ignore reality and believe that legal fantasy if you want. Personally this whole EV craze seems to me to be putting the cart before the horse (no pun intended). If EVs increase electricity consumption faster than zero emissions power sources (nuclear, renewables) can be built up to provide it, the logical thing that's going to happen is that power companies are going to build more coal and gas plants to generate that additional electricity. So the additional electricity generated to power EVs is going to almost entirely come from coal and gas. And when you do that, EVs aren't really that much more efficient than ICE vehicles.

Or to throw the market at it, letting the bad ideas die by sheer economic unfeasibility. We needed to have lots of different cable companies back in the 1980s and 1990s.

    Today, these problems have mostly been solved. Most Cable TV and Internet providers have standardized on the same solution for their networks (DOCSIS).

That's a pretty good sign that the industry is ready to be converted into a utility - with the government providing the pipes, while private companies provide the content. So this move to a municipal fiber network is the next logical step.

    You still need the ISPs though. How best to allocate shared bandwidth, most efficient way to interconnect multiple tier 1 and tier 2 networks with your ISP, negotiating deals with those upstream providers, whether bandwidth limits or monthly caps are the way to go, do you charge by GB of data consumed or use a flat monthly fee, etc. These problems all remain, and the solution space is cloudy enough that it's not at all obvious what's the best way to do each of these things. So you have the government provide the physical pipe as a utility, while private ISPs provide the content that flows through those pipes. And let competition filter out the bad ideas from the good.

    McFact No. 1: For years, McDonald's had known they had a problem with the way they make their coffee - that their coffee was served much hotter (at least 20 degrees more so) than at other restaurants.

    McFact No. 8: A report in Liability Week, September 29, 1997, indicated that Kathleen Gilliam, 73, suffered first degree burns when a cup of coffee spilled onto her lap. Reports also indicate that McDonald's consistently keeps its coffee at 185 degrees, still approximately 20 degrees hotter than at other restaurants. Third degree burns occur at this temperature in just two to seven seconds, requiring skin grafting, debridement and whirlpool treatments that cost tens of thousands of dollars and result in permanent disfigurement, extreme pain and disability to the victims for many months, and in some cases, years.

    The temperature of the McDonalds coffee machine specified in the lawsuit (195 F) was within the temperature range recommended by the National Coffee Association and Bunn, the largest manufacturer of coffee brewing machines sold in the U.S. 195 - 205 F.

    The legal team for the woman surveyed temperatures of coffee machines at a half dozen restaurants nearby the McDonalds, and deceptively reported that temperatures at other restaurants were "as low as" 165 F. Which is a useless statement since one restaurant could've had a broken machine and the other 5 could've been serving coffee at a higher temperature than McDonalds and the statement still would've been true. This is classic tricky phrasing used by lawyers to mislead the jury. It's where the "20 degrees hotter" statement comes from. The adjective that belongs in front is "at most 20 degrees hotter," but because of the tricky way the lawyers phrased it people mistakenly think it's "at least". If their research had actually shown McDonalds was serving coffee too hot, they would've reported the temperature of all 6 other restaurants they surveyed, not just one.

    McFact No. 2: McDonald's knew its coffee sometimes caused serious injuries - more than 700 incidents of scalding coffee burns in the past decade have been settled by the Corporation - and yet they never so much as consulted a burn expert regarding the issue.

    Those 700 incidents were over a period of something like 13 years when McDonalds sold billions of cups of coffee. I number crunched the statistics once. If you lived 5 miles from McDonalds and drove there to buy a cup of coffee and took it home, you were more likely to die in a traffic accident than to scald yourself by spilling their coffee. If their coffee was too dangerous for the public, then so is every car on the road.

    I want to say the figure was 18 billion cups of coffee served in that time, but honestly I don't recall exactly. If the 18 billion figure is correct, then those 700 incidents are equivalent to buying a cup of coffee at McDonalds every day, and spilling it on yourself once every 70,000 years. If anything, McDonalds should be getting an award for making a portable and minimal hot beverage container so safe.

    McFact No. 3: The woman involved in this infamous case suffered very serious injuries - third degree burns on her groin, thighs and buttocks that required skin grafts and a seven-day hospital stay.

    McFact No. 4: The woman, an 81-year old former department store clerk who had never before filed suit against anyone, said she wouldn't have brought the lawsuit against McDonald's had the Corporation not dismissed her request for compensation for medical bills.

Of course, this could still be overturned if Trump wins and gets to override the pick for the next Justice, nevermind that a GOP congress plus Trump would be free to pass whatever anti-net neutrality legislation they want, or to replace the pro-neutrality majority of the FCC commissioners with a Republican one.

    Historically, campaign contributions from the telecom industry have slightly favored Democrats (scroll to the bottom). And Hillary Clinton is by far the biggest recipient from that industry in recent years with 3.4x the money received by the second biggest recipient. Bernie Sanders is the third biggest recipient.

  22. Or how he'll do what NASA doesn't know how to do (land such a large vehicle).

    The Falcon 9's first stage weight is estimated to be about 25 tons when empty. That's the stage that returns to Earth (or sea) and lands.

    The space shuttle weighed about 82.5 tons when empty. Mars' gravity is about 38% that of Earths. 82.5 tons * 38% = weight equivalent to about 31 tons. So aside from inertia, the practice Space X has been getting landing the Falcon 9 translates almost exactly into landing a space shuttle-sized craft vertically on Mars.

    Agreed that radiation is a huge problem. I think oxygen generation and recycling water and waste materials are equally daunting problems (it's unrealistic to carry enough oxygen, water, and CO2 scrubbers for a 2.5 year mission). We've just begun tackling those issues.

    The important figure would be number of violations per 100,000 packages shipped. Not raw number of packages in violation.

    Number of times they got caught vs. the number of times they got away with it is mostly irrelevant. Since other people/companies shipping hazardous materials will probably have a similar ratio of times caught to times they got away with it. So you can just compare the easy-to-determine number of times caught per 100,000 shipments across companies, and that'll give you pretty much the same ranking order as the much-harder-to-determine number of times they got away with it per 100,000 shipments.

  24. Unfortunately, it's like spam on Microsoft Is Buying LinkedIn For $26.2 Billion (microsoft.com) · · Score: 1

    Obviously they'll be monetizing it by charging experts for the right to appear as an Office 365 recommendation. It costs Microsoft nothing to present these ads to Office users. So even if these ads annoy 99.9% of us, if just 0.1% respond and pay the advertised expert, it becomes "worth it" to them.

    Given how Microsoft shoved a lot of the telemetry features of Windows 10 down the throats of Windows 7 and 8 users via updates, I'm going to be proactive and start turning off the "Give me updates for Microsoft products and check for new optional Microsoft software when I update Windows" option on all my computers with older versions of Office installed.

    What would help us a less violent surrounding, i.e. less guns.

    You mean like France?

    It's important to understand that both this incident and the France terrorist attacks were outliers. The availability of guns (or lack of) doesn't make a difference when you have a determined assailant(s). They will figure out some way to do what they want to do, whether it be by smuggling in guns or building alternate weapons (bombs).
