    If anything, this code tells me that whoever wrote it was very careful not to use bad data. Why else would you mark the modification with a three line comment with big letters and double exclamation marks pointing out that the following lines are artificial? The only time I write comments like that is when I want to make sure nobody accidentally compiles the code with it still in there.

    But the premise of this whole debacle is that people are not given a choice of browser when they install an OS, and that is the reason that IE has such a large market share (since it's installed by default).

    The choice has always been there, albeit more complicated to make. The issue has been that Microsoft has promoted their browser through their operating system monopoly, leading to unfair competition, not that people haven't been given a choice per se.

    I personally don't think it is a big issue whether the ballot should be random or not. It sounds more like they are quibbling about details. But if the goal is to remove the leverage MS has through controlling the operating system, I'd say a random ballot ought to be more "fair" than letting MS pick the order. Sure, those who don't care will get a random browser, but why should MS be given the advantage of getting (more of) those users?

    I hear what you are saying. But at the same time I hear China and others pointing out that historically the west has released much more carbon, that they release less per capita and that the west have much greater capabilities for transforming their societies. I'm not saying that they are right, but they do have a point. So for them you are the one that don't want the same standards.

    The question is, what standards should we have? Hence my conclusion: During the following years we will be given the choice between cooperating and working out our differences, or being overly protective and quibble until we are all doomed.

    Also I'm not sure why you would need to limit carbon emissions using taxes. Cap and trade seems like a much more efficient and fair method, and it also what the EU employs. It could be implemented on a global scale if the willingness was there.

    Every time I read something like this, I'm getting even more convinced that the following decades will define us as human beings. We can either work together globally, people from every culture and every nation, and unite to solve one of the greatest challenges our civilization has faced, or we can make it into a struggle about power and greed, fighting and distrusting others on our way into mutual disaster.

    I think it is unfortunate that westerners in general, and Americans in particular, habitually see enemies wherever they look. I guess it comes with being a superpower, but I fear it will become the primary factor contributing to the eventual downfall of western dominance.

    If a kettle takes half as much electricity to boil water than it did before, you can boil twice as much water with the same electricity right? You end up using more hot water for other purposes? Like more tea.

    Or you can continue to boil the same amount of water and reduce carbon emissions without reducing your standard of living.

    I must say I find the summary somewhat contradictory: Higher efficiency is said to spur the economy, at the same time it says that "that rising carbon dioxide emissions cannot be stabilized unless the world's economy collapses". If higher efficiency spurs the economy, then there must be room for reducing energy use without an economic collapse.

    Regardless, the emission trading being implemented in Europe is designed to limit our freedoms as little as possible and focuses right on the problem. Cap the total emission levels and let people trade with certificates (using the market handle allocation and costs). You can still drive your huge car, but if it emits a lot of fossilized carbon you'll pay for it accordingly (indirectly through the petrol cost). Run it on electricity and you pay nothing.

    The government has no control at all other than setting the cap, which is exactly the one thing we should decide democratically.

    The only problem is they set the initial cap so high above the actual emission levels that the price for carbon emissions dropped to zero.

    Yes, doctors have licenses. But that doesn't make them perfect. They are not even objective. Medicine is a complex science that involves lots of intuition and judgement based on experience. Take a hundred thousand doctors and an insurance company will easily find someone agreeing with them. Especially if they give him a good salary.

    In theory, you could try to revoke the license of these doctors, but that isn't going to be easy. And nor should it. How are you going to prove malpractice if all he/she did was to advice an insurance company? Because their "best judgement" wasn't accurate enough? Because they were paid by an insurance company?

    The bottom line is the insurance company shouldn't be allowed to choose which doctor arbitrates the case. If they can, they will cherrypick one.

    I just checked these numbers. They are quite accurate, but interestingly, the difference is made up of almost entirely of taxes. The power company adds less than 10% to the spot price, so bulk seems to have little to do with it.

    In my case the price is 9.33 euro cents per kWh. This is made up of:
    Spot price: 3.81 cents (41%)
    Added by the power company: 0.35 cents (3.7%)
    Taxes and certificates: 5.17 cents (55%)

    When buying in bulk, the interesting figure is the spot price. Where I live, electricity is traded on a public exchange (Nordpool), so you can easily check the price per MWh at any time.

    The problem isn't that I haven't connected all the dots; the problem is that you don't understand the principles well enough to see that I have.

    Let's be concrete. Some of the dots I'm missing are:

    • What is the power output of the laser?
    • For how long can the laser pulse be sustained?
    • How stationary can you keep the spot of the laser?
    • What level of heat transfer and heat capacity can you achieve in the surface?
    • What happens when/if the surface material evaporates? Does the gas absorb or disperse any of the energy?
    • If the reflective surface is polluted with dirt, how much heat will the dirt transmit to the surface before evaporating?
    • Does the reflectivity change somehow under extremely intense lighting (due to depletion of surface electrons or whatever other imaginable reason)? (High energy laser knowledge could be useful here.)
    • And finally, what reflectivity is actually reasonable to achieve? These kinds of chemical laser have wave lengths in the order of a few microns. In this range even very thin layers of gold plating have very good reflectivity (> 98%). Gold also doesn't corrode and it transfers heat well. On the other hand, the surface would not be perfectly clean, as you have pointed out.

    Now, we know that the laser evidently can destroy an aircraft with "normal" reflectivity at some distance. What we don't know is: With how large a margin? Perhaps a twice as reflective surface would be able to maintain the heat transfer induced by the laser without melting or evaporating. I'm guessing probably not, but that is just a guess.

    I don't think this is such an obviously simple problem, but if you do I'd happily be educated. (Preferably with numbers.)

    4) "shouldn't be hard to substantiate (other than giving numbers on mirror reflectivity)"? The hell you say? If 2 plus 2 is obviously 4, then you should be able to prove it easily without using integers.

    Sure. If you like I can roll out the full proof using the Peano axioms.
