    Yeah. The title of the paper is a bit misleading.

    They are studying the case of some betting game with a fixed probability of winning p (with p>1/2) and a fixed 1:1 payout, using a discrete model of money, with no maximum bet, a minimum bet of $1, and all bets being constrained to a multiple of $1.

    It is already known that if you enter with x dollars and you have a target amount of N, your best strategy is to always bet the minimum. Needless to say always betting the minimum can take forever, so even under this very unlikely set of circumstances, you would not want to actually follow that strategy.

    So instead they introduce a round limit T, and introduce software that solves the relevant dynamic programming recurrence determine what you should bet given the probability p, your current balance x', your desired amount N, and the remaining number of rounds until the loan shark kills you T'.

    Judges rule on Law, but Juries do not rule on facts in criminal cases. [1] If juries ruled on facts they would be required to give their verdicts like so:

    We find that there is no reasonable doubt that the defendant physically caused the death of Jane Smith, that there is no reasonable doubt that the defendant intended to cause grievous bodily harm or death, and that there is reasonable doubt that the actions were premeditated. Therefore, in accordance with the law as outlined by the Judge, on the charge of first degree murder we find the defendant Not Guilty. In accordance with the law as outlined by the Judge, on the charge of Second Degree murder, we find the defendant Guilty.

    We however do not require juries to state a verdict like that, which means that juries inherently rule on both law and facts, since there is nothing to prevent them from doing otherwise.

ICANN in conjunction with Verisign could get the transfer reverted, but since that requires two entities working in concert, I would not count on it happening.

    If you want to be Canadian, you should have to renounce your citizenship to your former country or not become Canadian.

    I'm not sure I agree with that, especially since people do not necessarily have only control over their citizenship in other countries. Some countries may not allow a citizen to renounce citizenship or that doing so may not be effective.

    Consider that US law requires renouncing other citizenship to become a naturalized citizen. The US knows that is little more than a joke. The laws for relinquishing US citizenship require that an action (like renouncing) be taken with the intent to relinquish citizenship. Doing so only to satisfy a requirement of another country's naturalization process does not result in loss of US citizenship. That is settled law, and there is absolutely no ambiguity about it. So US citizens who became Canadian citizens under such a requirement would end up with dual citizenship, if they so desired. Similarly, citizens of any country with similar laws on relinquishing citizenship are not impacted by the US requirement to renounce other citizenship.

    At the minimum, you shouldn't expect any help if you get into trouble outside of Canada, especially in your former country that you hold your dual citizenship in.

    While a dual-citizen is in a third country, Canada should attempt to provide assistance if requested, but I fully agree that in the second country that the person has citizenship in, they should not expect any help, except in two cases:

    • They remained a citizen of this other country, not out of choice, but because they were unable to relinquish citizenship in this country, or that doing so would have involved jumping through excessive hoops.
    • They are citizens of the country they are in by some automatic means (like birthright citizenship), and they have never utilized said citizenship in any way. It is entirely possible for somebody to be a citizen of multiple countries by birth, and it is unreasonable to require that they take any explicit action to relinquish said citizenship, especially since they may not even be aware that they are technically citizens of the country in question.

    Sure. But how revered? Although King is generally not an elected position, what sort of approval rating would "widely revered" translate too? 85%? 75%? 51%? 25%?
    Any of those could be considered "widely revered", but there are major differences between them.

    Let me go on the record as saying that it is generally not in the long term interests of any leader of a country to silence criticism. Any benevolent leader of a country has a vested interest in knowing how the public feels about their actions. No leader has perfect information, and such feedback is invaluable. Granted a benevolent leader will not always be entirely popular. Sometimes the actions best for the people are not popular. Even so, if something the leader though would be popular was not, or an action was unpopular for a reason other than the expected one, that provides valuable information.

    A leader who is not benevolent had better at least appear benevolent, which means not silencing criticism for similar reasons. Leaders who do not at least pretend to have the interests of the people at heart generally get overthrown or removed by the people. It may take a while, but it usually happens.

    A leader's best bet is to embrace criticism and occasionally make changes to satisfy critics. Whether the leader has the peoples interests at heart or his own, he can best accomplish things by remaining in power.

    As for the dynamic range compression, I agree with you that it is a problem, but I was under the impression that record producers applied it to M4As from the iTunes Store and MP3s from Amazon MP3 just as much as to CDs.

    I'd be surprised if the producers did not do exactly the same thing to both.

    As for the 44.1 kHz sample rate, can you ABX the difference between a 96 kHz sample and the same 96 kHz sample with all frequencies over 20 kHz filtered out?

    Keep in mind that the Nyquist Sampling Theorem only strictly applies to perfectly periodic signals. Second many people can hear frequencies somewhat above 20Khz. Third, the ear does not strictly separate audio by frequency, and actual waveform has some effect. Thus it is entirely possible to construct a waveform where the difference between 96 kHz sampling and 96kHz sampling with frequencies above 20Hz filtered do sound distinct. I'll admit though that for most audio the difference is not noticeable even by experts.

    But CD audio is sill lossy relative to recording masters, and all recorded audio is strictly lossy relative to original sound waves. To make the mistake of believin otherwise is madness.

    Otherwise kexec is the indeed the only option, but it is completely feasible.

    Not dithering -- just cumulative addition. The more reflecting elements there are, the more color you get. So each pixel is a series of imod elements, arrays of R, G and B. Black is all off; dark color is just a few on... medium color is half of 'em on... bright color is all of 'em on.

    That is the very definition of dithering. Imagine a version of the display with only red pixels (for simplicity). That is a display with a 1 bit color pallet. You either have bright red or black. You want something in between so you create a pattern where 50 percent of the pixel are red, and 50 percent are black. That is dithering, no different than the classic example of a checkerboard pattern of red and blue pixels to create the appearance of purple.

    To maximize the advertised PPI of these displays I find it unlikely that they will actually pre-group a bunch of elements into hrdware pixels, which would avoid the need of inter-pixel dithering. Instead they will most likely expose a triad of elements as a hardware pixel, and let the software chose how to handle things. The software could group large arrays as a logical pixel, but at the cost of not appearing as sharp as the display allows, so instead most software will opt to controlling individual elements, which would allow sharper images at the cost of more work.

The inexperienced developers have not yet developed good practices to ensure they don't overflow a buffer. Similarly they don't understand ownership of allocated memory, so they end up either freeing memory owned by other code, or failing to free memory when ownership is passed to their code.

    If experienced developers carefully reviewed the code, these sorts of problems would be noticed and corrected, and things are fine. Unfortunately, real code review is somewhat rare in the business world, as are static analyzers that would also tend to catch many of these same mistakes.
