This model does not resemble a free economy at all. Not only it doesn't consider the wealth-creation aspect of a free economy, but it assumes people "wagers" their wealth. No society does this and is a terrible model of how an economy works. Most people earn their wages, if they have some money left they may save that, but long term saving is not comparable with a bet on a coin flip, if you think it is, then you should not save at all because you will go broke with probability one. Again, that is not what happens in our societies.

Jumping to the conclusion that "taxing the rich" could solve anything is completely wrong. You would just make things more expensive and add extra incentives to take jobs abroad. It doesn't matter that the model is too simplistic, the problem is that this model is too far from reality.

I feel this discussion always misses an important point. The value of something has nothing to do with its costs or profits. The value of things (labor included) is subjective and is normally related to its scarcity. In the period analyzed the workforce basically doubled because the inclusion of woman to the workforce, therefore it had a huge pressure to keep it low.

Does this means that Emacs will now be usable on remote desktops such as x2go? It tends to close by itself and, if I remember correctly, it was related to some redrawing issue that, I hope, could be solved by this.

Could this endeavour be detrimental to the environment? (Please read my whole reasoning before calling me a Climate Change Denier or something like that)

I understand that humans are changing the Earth's environment, but with this we need to acknowledge that other organisms are doing it too. In particular plants have been taking CO2 from the atmosphere for ages and continue to do so. If you look at CO2 concentrations for long periods of time, you'll find that the levels of today are not very different from what has happened cyclically for hundreds of thousands of years.

The difference may be on the fact that now we are adding an extra influx of CO2 to the atmosphere, but in doing so we may be balancing greater concentrations of water vapour, which is a much more efficient greenhouse gas. If doubling the concentration of CO2 increases the temperature of the atmosphere, in say one degree, to gain another degree you'll need to double the concentration of CO2 again, so the effect of concentration of CO2 on temperature is logarithmic. Water vapour is much more efficient and by decreasing the amount of CO2 in the atmosphere we may increase the amount of water.

This is because of how photosynthesis (and agriculture) works. A plant breathes air in through small pores on their leaves called stomata. Doing so allows water to evaporate through those same pores. If the concentration of CO2 in the air is low, the plant will need to evaporate more water to absorb the same amount of CO2. On the other hand, if the plant doesn't have enough water to evaporate, it will close its stomata and the result will be lower growth and poor yield, simply because of the lack of carbon. Since nowadays many agricultural plots are using water from aquifers and other underground sources, we are actually putting into the environment much more water than would have been without agriculture. If we decrease the amount of CO2 we may push even further the plant's need for water and produce more water vapour, pushing even further the warming, since water is much more effective than CO2 as a greenhouse gas.

We may be fighting against the wrong enemy. And in doing so punishing unfairly the poorest of the world, who rely on fossil fuel for energy and those who will be the most affected when crop yields start falling and the water available becomes insufficient.

I haven't been able to find a global warming model that incorporates this effect, but if someone made it this far into this comment and knows of any model that does, I'll be very grateful to hear from it. If someone related to this project reads this, please discuss it. It may be a mute point because some reason that I don't know, but it may very well be an important one.

But here you are not talking about coal. The alternative is not a more polluting fuel, is another person that is also very unhappy his opportunity was taken away because he had the wrong gender. We all agree that situation sucks, so we don't make a net possitive by making more people misserable AND being less productive.

Where I live doctors are only allowed to give prescriptions for the generic chemical compound and are forbidden to give prescriptions for specific brands. They may suggest the use of a particular brand if they know of a benefit over others but the one who decides is the patient. Of course this is not very useful when the drug is patented or if there is only one laboratory producing it, but none the less it seems like a sane default. And this is in a private healthcare system, it is surprising that the NHS doesn't have a rule like this when is their taxpayer's money being used.

Not a libertarian nor a bitcoin fan, but I have to disagree with OP. First, he postulates a gedankenexperiment where bitcoin replaces the dollar, but since it tends to appreciate in value, no one actually spends their money, so the economy halts. This train of though obviously neglects the fact that, if it actually replaced the dollar, people would _need_ to use and spend their bitcoins, so its price action would be very different to what we have seen.

Then he goes and mocks the idea of having a trustless currency system but IMO he misunderstands the idea. If you use the currency for exchange you still have to trust other people, for instance if I use bitcoin on Amazon, I'd still need to trust Amazon and possibly some other merchant. The part of trust you are taking away is not between people, but towards the ability of the State to issue money and regulate its value. But then libertarians may come up with some other ways to achieve this that do not involve cryptocurrencies. Furthermore, you don't need to be a libertarian to agree on that principle. One example of this is Chilean Central Bank, which -unlike the FED and by the Chilean constitution- cannot buy the government's debt, so the government can't just keep printing money for political reasons, like many countries in the region have been doing for decades.

So whatever lesson he is trying to teach seems a bit farfetched. Bitcoin may die and not mean a single thing for libertarianism, because IMO it's success depends on technical implementation, not ideological barriers.

They do say that they adjust for "patient characteristics", although they don't go into much detail. Also it's important to note that physicians that have a large volume of patients don't have a higher mortality rate on their patients. It looks like a real effect, maybe from "staying behind" or maybe simply not being on the "top of their game".

Not only that, but it fails to consider that many times, a large wealth, is not built with an extra 1% per year, but by one large hit. People have failed 20 years to then become rich on one good idea. You could call it luck, but to be realistic that's not luck, that's perseverance, work ethics and commitment to do something important. I agree we need to look for a way to build a more even play field and remedy the atrocious way we assign resources, but claiming that people that work hard to make a difference are just "lucky" is a terrible way to do it.

I'd just like to point out that the "war" developing is not so much between advertising and ad-blockers. I think most of us would be fine with advertising on some page you are visiting. The real problem comes from trackers and other tactics that don't try to show a product TO you, but try to show YOU to a company. The problem is not that I don't want to see advertising, I just don't want to share my information with someone I don't even know. Maybe there is a way in between.

It could be that I'm misunderstanding the problem, but I don't think that, in general, makes a lot of sense to define functions acting on NA values. What you really want are functions acting on arrays that may be missing some values, but not necessarily functions that can act on those missing values. This is because the NA values are an effect of the data tabulation, not some deeper mathematical necessity. In that sense, wouldn't it be much easier to endow every array with another list with the places where values are not available and define procedures that use other underlying functions to compute the results while filtering out the NAs? For instance, you could have two "mean" functions, one that filters NAs and then returns the mean of the rest, and another that returns the mean of the whole array and if there is an NA it just returns NA. Both functions could use the mean(x::Number) function but just wrap it in a different way. Or is this missing the point completely?
