<p>Who is blaming the students? If 13 year olds were smoking and we blamed poor sports performance in that age group on the smoking, we wouldn't be "blaming" them. We don't model 13 year olds as little islands of free will.</p>

<p>A revelation of a mysterious element of the game which is not revealed in any of its marketing material is a spoiler. The fact that you believe it's a "decent compromise" doesn't enter into it. The proper disclaimer for your comment would be: "Spoilers, but I think these things should be spoiled."<p>I played the game years ago and did not have this element spoiled, and I thought it was presented at exactly the right time and in the right way. I'd go so far as to say that if somebody is so frustrated by that early mystery (which you're all but guaranteed to understand better and better as you play) that they quit there, then the rest of the game will just be an exercise in misery. It's a puzzle game. The developers put settings in place to cut the flight mechanics out of it so people could just experience it as a puzzle box instead of a flight simulator as well. What they did NOT put in the game is a hint about the thing you're spoiling.</p>

<p>I think that's a little harsh. A lot of the most powerful bits are applicable to any intelligence that we could digitally (ergo casually) instantiate or extinguish.<p>While it may seem that the origin of those intelligences is more likely to be some kind of reinforcement-learning algorithm trained on diverse datasets instead of a simulation of a human brain, the way we might treat them isn't any less though provoking.</p>

<p>But there's a reason that caches are always sized in powers of two as well, and that same reason is applicable to high-performance ring buffers: Division by powers of two is easy and easy is fast. It's reliably a single cycle, compared to division by arbitrary 32bit integers which can be 8-30 cycles depending on CPU.<p>Also, there's another benefit downstream of that one: Powers of two work as a schelling point for allocations. Picking powers of two for resizable vectors maximizes "good luck" when you malloc/realloc in most allocators, in part because e.g. a buddy allocator is probably also implemented using power-of-two allocations for the above reason, but also for the plain reason that other users of the same allocator are more likely to have requested power of two allocations. Spontaneous coordination is a benefit all its own. Almost supernatural! :)</p>

<p>Speaking from a place of long-term frustration with Java, some compiler authors just absolutely hate exposing the ability to hint/force optimizations. Never mind that it might improve performance for N-5 and N+5 major releases, it might be meaningless or unhelpful or difficult to maintain in a release ten years from now, so it must not be exposed today.</p>

<p>No disagreement here, but where the literal rubber hits the road, you still have to decide how to act when the ambient semi-aggressive driving population continues to behave in the way that they do. Will you blamelessly be road raged at 50-100% more often than a more moderate driver (who drives at the most popular speed, though it may be over the limit) just because if an accident does happen it will be the road rager's fault?<p>It's a very frustrating social problem. Obviously we can't let ourselves be held collectively hostage by bad actors in all situations. But I would still predict that there are some situations where the bad actor population is so large and "mildly-bad" that indefinitely giving in to their implicit demands is the right game theoretic choice.</p>

<p>Assigning blame doesn't do anything for safety, even if you're right. Where I live, by far the safest thing to do is to drive ~4 mph over the limit on all non-residential roads. If you drive below or even right at the limit, you will be tailgated or passed with far greater frequency. <i>That behavior is out of your control</i>, at least on the road. You can push for more consistent enforcement while you're not driving (I'm inclined to do so myself), but while you're behind the wheel, the only behavior you can change is your own.</p>

<p>There is no year zero according to first-order pedants. Second-order pedants know that there is a year zero in both the astronomical year numbering system and in ISO 8601, so whether or not there is a year zero depends on context.<p>It's ultimately up to us to decide how to project our relatively young calendar system way back into the past before it was invented. Year zero makes everything nice. Be like astronomers and be like ISO. Choose year zero.</p>

<p>> Solitary confinement is used in quarantine...<p>This is just abuse of the phrase "solitary confinement". Yes, people in quarantine may be confined in solitude, but "solitary confinement" as a phrase has a particular connotation that is not applicable to quarantine.<p>> ...and penal settings without being "commonly" accepted as being torture.<p>It is recognized as a form of torture, commonly. The fact that you keep saying otherwise doesn't make it not so[0].<p>> The purpose isn't to cause harm...<p>That's an interesting interpretation! Valid, I suppose, but certainly not something you can just assert in passing. The purpose of torturing enemy spies is to get information that might stop a war, which on net reduces harm. Really, is the purpose of <i>anything</i> to cause harm?<p>In my view, the treatment of the child is purposefully portrayed as unthinkably cruel. It stops short of being <i>graphic</i>; they don't flay the child or stick bamboo shoots under its fingernails. But they do actively confine it; it's strongly implied that they will not permit it to simply leave, or even die. They don't make any effort to clean its living space! <i>They kick it for no reason!</i><p>Go re-read the passage that describes the child's living conditions again. I don't know how the author could make it more clear that the arrangement is <i>cruel</i>. It's not like the people were given some absurd set of requirements for prosperity involving a confined child, and then did everything in their power to at least make it easy on the kid. Or, perhaps they have done everything in their power to that effect, but the requirements include cruelty itself. Either way, I'm not seeing how you think it is <i>so incorrect</i> to describe it as torture that you felt the need to directly contradict my use of that word.<p>If I described the conditions on the transatlantic slave ships as "torture", would you go out of your way to reject my use of that word because of the lack of intent to cause harm? Or would you accept the combination of the abject human misery, the sores, the starvation, the wallowing-in-excrement, the confinement, along with the fact that these conditions were inflicted by fellow humans, as sufficient basis for that descriptor? Because all of those things are true of both the Omelas child and the slave ships, and in neither case is it clear that the sole intent was to harm.<p>0. <a href="https://en.wikipedia.org/wiki/Solitary_confinement#Torture" rel="nofollow">https://en.wikipedia.org/wiki/Solitary_confinement#Torture</a></p>
