    The Tesla can do 300 miles on a single charge today, and with the improvements in battery technology, 600 miles is not infeasible in the near future.

    The battery on an electric vehicle can be swapped for a fully charged one, and I can see one day a network of battery swap stations. All that is needed is for some standardisation of the batteries and "recharging" will be quicker than refuelling. One could change their battery in a minute and be off.

    The distribution of fuel would essentially be done by power lines to the battery swap stations, which would be more efficient than moving billions of litres of oil from Saudi Arabia, Canada and Venezuela to the US every year, and then moving them around the country to where they are needed.

    Argument from apathy?

    This is just another case of Stallman's ideological purity doing more harm to his cause than good.

    How so? I would argue that this drives home the point for Stallman that GCC needs to be better.

    Except that the ideology does get in the way. Stallman (or whoever is responsible for GCC) decided that they wouldn't make GCC to be modular to force people to use it in the way they wanted them to. Then they changed the license to make it harder for Apple (and others) to make it do what Apple needed it to do.

    So Apple didn't sulk. They went and invested in LLVM, and Stallman's gambit failed. Now LLVM is starting to beat GCC in many important ways, and is getting the kind of traction that having companies like Apple on board can allow it to have. Even companies such as Google are contributing significantly to LLVM/Clang. At some point, LLVM will surpass GCC, and GCC will stagnate because all those people currently paid to work on GCC will no longer be paid to work on it. And make no mistake, GCC developed as much as it did because companies paid brilliant developers lot of money to make it work as well as it now does.

    I have only driven 400 miles in one day about 4 times in my life. Would my life be demonstrably worse if I had to take the train to the nearest station to my destination and hired a car for use while I was there.

    This is the equivalent of a computer geek demanding that their computer come with the ability to install their favourite operating system. If the mass market shifts to electric cars, you will just have to pay top dollar for a car that does 400 miles, and at that point you will ask yourself if the extra $10,000 it costs (for example) is worth getting the 400 mile range that you only really use once or twice a year.

    And if 99% of people decide that gasoline cars are yesterday's news, the situation could easily be reversed, i.e. there will be fewer places to refuel, and you will find it hard to fill up virtually anywhere, unlike electric, which you will be able to recharge everywhere. Of course, this future is a long way away, but there is no reason to imagine it can't happen.

  11. Re:Using MAD moves in the wrong direction on Why Standard Deviation Should Be Retired From Scientific Use · · Score: 2

    Um, yes it does.

    if you imagine a random draw in which you had 99 realisations of the number "1" and 1 realisation of the number "101". The mean would equal 2 while the (population) standard deviation would equal sqrt(1/100*(99+99^2)) (which is a fairly large number).

    If you removed the one observation of "101" from the sample, you would have zero standard deviation. So one additional outlier will cause the standard deviation to go from zero to 10 without changing the mean by nearly as much (or the median at all).

    The issue of underweighting tail events is really a separate issue, and that is usually because a distribution such as the normal distribution has very thin tails, so basically anything outside about 4 standard deviations would be predicted to be extremely unlikely by the normal distribution.

    Other distributions do better, but they tend to be rather less friendly from an analytical perspective. However, with the kind of computing power available nowadays, this is less of an issue now as it would have been when people first started using the normal distribution for the purposes for which it has been always known (and some not so clever bankers have recently found) to be inadequate.

    I should add that it is still a bit of an issue where speed is concerned though, because you can do your calculations involving the normal distribution much faster than you can many of the other more esoteric and likely more realistic distributions.

    Actually, if that is the whole population of interest, then that is the standard deviation. If that is only a sample, then as an estimator, and it is biased. That's when you need to use the unbiased estimator to estimate the standard deviation for the population.

    As your sample becomes larger, it begins to matter less anyway (the difference between dividing my n and dividing by n-1 becomes tiny the larger n gets).

    I tend to have less hangups about using either to be honest if all I am looking for is a measure of the dispersion in the population. Of course, if I want to score full marks in a test, I use the right one.

    I think the bigger problem is that while in the past, the new jobs were often created nearby where the people already were, these days, those jobs can be displaced halfway across the world in China. The reason Obama had to save Detroit was that all those autoworkers couldn't just up sticks and move to China, or Japan or wherever the new jobs were popping up. In the past, if one car company went under, they would either be snapped up by another company in the same area, or new companies would pop up in the same place to take advantage of the local skills. Now cars arrive from Europe, Japan and China in kits, and can be assembled anywhere, probably somewhere coastal.

    Back in the day, industries declined slowly, so while the number of jobs fell, this was manageable because you just stopped replacing the people who retired or quit. Now, entire industries can disappear overnight.

    Additionally, the speed with which industries grow and then shrivel and die is now quite mind blowing. PC repair shops were a big thing in the late 90s and early 2000s, but are largely disappearing as it has become cheaper to replace rather than repair.

    Also, for decades previously, all manner of goods would have been repaired, and those repair jobs would have been local. When you repair something, you pay someone in your town. When you replace (via Amazon), its to the benefit of a company in China (or Japan, or Europe somewhere).

    A currency is both a medium of exchange and a store of value. The two things go hand in hand. A currency is what allows you to work work today, be paid in a month and spend your money a year later. If the currency can't store its value reliably, then people will not accept it, and it loses its ability to function as a currency.

    Storing its value allows a currency to perform the inter-temporal transfer of wealth function.

    Money supply is number of units in circulation x value per unit. You are just used to the left hand term varying, but mathematically the right hand term can do the varying while the left one stays fixed.

    Basically, in your "equation", if I understood correctly, you are saying that the number of units stays fixed while the value varies. I am saying you want both to be fairly stable. You want the amount of currency in circulation to be fairly stable and linked to the amount of economic activity and thus increase as the value of economic activity increases, and you want the value to be fairly stable to allow holders to store their wealth in it.

    If the value cannot be stable, then you can't keep your "money" in Bitcoin. If you can't keep your wealth in Bitcoin, then why would you accept Bitcoin in the first place? Why not just demand dollars and avoid having to transact into and out of Bitcoin?

    One of the reasons that gold stopped being useful as a currency as that the amount of gold in circulation had no direct (or indirect) link to the amount of economic activity. The value of gold fluctuates too much compared to the value of the commodities that you would want ot buy with the gold. If you don't believe it, just look at what the price of gold has been doing over the last 10 years.

    Bitcoin would be even worse since it is designed with very specific finite limits. Yes gold is also finite, but we have been mining the stuff for millenia, and we are still producing a fair amount of it.

    A currency ideally need to be linked to the amount of economic activity to prevent wild swings in its value. So if the economy grows by 2%, you would want at least 2% growth in the amount of currency available. Bitcoin is unable to do that indefinitely. I would add that ideally, the amount of Bitcoin needed to increase to reflect the amount of transactions being undertaken in Bitcoin. Bitcoin does not do this.

    Secondly, a currency needs a little bit of inflation. Bitcoin, at least at the moment, has the opposite of that. Because the value of Bitcoin has been rising, people are encouraged to hoard Bitcoin (you become wealthier just by holding on to them). You want the opposite. You want people to become a little poorer if they just hold on to their currency to encourage them to either spend of invest their money. This may be a little controversial, but there is no good reason why the intertemporal transfer of wealth should be costless.

    Because of these flaws Bitcoin cannot be a currency. At best, it will be another commodity (like gold, or oil or copper), whose value swings wildly depending on the mood and the outlook.
