@PerttiRuismäki "A system that has only one variable cannot do any calculations". ⇒ so, a counter cannot do a calculation? What is your definition of calculation?

@Betternottell the discussion definitely did not bring a consensus. You might have a look here if interested: meta.stackexchange.com/questions/369568/…

@Betternottell answers are sorted by community approval. There was a discussion a few months ago, and it came to the conclusion the person asking the question is by definition the least qualified to evaluate the answers, thus their approval should not make a significant difference.

This article from BBC news mentions the FAA recorded about 100 occurrences in total, of which ¼ survived. Usually on shorter flights, that typically don't reach the same altitude. This figure is probably skewed by the fact people who don't make it are likely not to be recorded (compartment doors re-opening above the sea or uninhabited area for instance).

@Betternottell you cannot draw general conclusions based on an exceptional, statistically irrelevant event. Remember that the very reason you know about him in the first place is because survival is so improbable it made the news.

@gerrit unless you personally take several tests, all being negative, before going on a plane, you're being entirely irresponsible by your own rule. Just look up the rate of false negatives on PCR tests.

@PeterM tested negative does not mean not infectious either. All tests can produce false negatives. Either you need to set some arbitrary threshold you are happy with, or you cannot take the plane at all.

Well your point as I understand it is you believe everything observable about the presence of PHP can be hidden through configuration. But then I cannot be sure that is what you want to say.

@schroeder If am sure enough to take a bet 1 to 100. That's more that what an attacker needs to decide to crack your PHP. Now if you want to play it stupid with numbers, then yes you cannot be sure of anything. Perhaps I do not even exist, and pure luck made static noise post that message. It is mathematically possible, so you cannot be sure of the opposite.

@Barmar> the assumption is the belief that everything observable about the presence of php can be configured.
spectras
Jun 25, 2021 12:07
@schroeder that statement is a declarative absolute. it is not possible to know for sure → the "it is not possible" is as absolute a declaration can be. And it is wrong too, for reasonable degrees of certainty. Eg if I see a well-known wordpress theme on a page with a typical wordpress layout, I am ready to bet PHP is used. Yet this does not imply the server is misconfigured, unless you define "run wordpress" as misconfigured.

@MikeBrockington> this example clearly considers this statement not from the "fact" standpoint but the "what everyone believes about it is actually wrong" standpoint. Plus if I wanted to nitpick on the nitpick, I would argue you're quite fast giving predicate quality to a statement that is not even clearly defined (which William Shakespeare? what does "alive" actually mean in physics terms?)

Though this is interesting, I would like to point out ignoring facts that go against one's opinions is one of the key features of human psychology in general, not just in the US. Therefore I am not sure this really explains why this would have this result in the US and not in other places.

I think Karl nailed it. The initial stabilization is way too random with having to deal with starvation, and many answers revolve around the question of how much cannibalism is needed. Give them 1 month worth of rations when dropping them, so they at least have some time to test food sources to differentiate edible and poisonous stuff, and get their body accustomed.

@RedwolfPrograms> it is possible indeed. However poisons are very deceptive, for instance swainsonine (a toxin produced by several plants in North America) disables glycoproteins, making your body unable to process food. This causes no pain, but you will die of starvation a week later, regardless of what you eat after.
And well… we're assuming you can touch the plant… some plants are so poisonous they can kill you from contact.

The US army survival guide describes a full safe procedure. It takes quite a few more steps (tasting is like step 4 or 5), and overall a couple of weeks.

Generally speaking, "easily available food" is an impossible thing to get naturally. If food is easy to get, species that can take advantage of them will strive until either they deplete them, or they become another specie's food. With more resources, you get longer food chains, but none of the links can be easy to get.

@RedwolfPrograms> a large majority of berries are poisonous. So unless either the granted knowledge includes that of extraterrestrial berries or we can define the world to not have poisonous berries, that does not help much (in that case let's just define it as having domesticated crops growing naturally and be done with it).

I guess they could organize themselves and do systematic testing to limit the number of deaths before they know enough edible species to make it a viable source of food.

Perhaps it's easier to picture it like this: imagine a bunch of pillows, just enough to make the shape of a human body, floating around in space. Now, throw someone into them at 100km/h. They will be hurt pretty bad, assuming a regular pillow (what matters is a combination of its mass and its ability to bend and compress - pillows are just too dense).
spectras
Jan 9, 2020 01:07
@NuclearWang. Before even considering the compression of pillows below the next layers, just look at the top layer. Say they are 20cm thick. That means by the time the jumper has traveled those 20cm, he must have pushed all pillows of that layer away. That is about 7ms. Unless the pillows are unrealistically light, the required force is large.
spectras
Jan 9, 2020 01:07
@anaximander The issue is that to shove pillows aside you must transfer them your energy. To send a mass equivalent to yours fast enough than they free the way for yourself, means transferring almost all your kinetic energy to them. The problem is not that pillows are bound, but that their mass will crush the jumper as he accelerates them to the sides.

@PatriciaShanahan modern compilers have been doing loop unrolling automatically for years, if not decades. And they do it better than programmers. Doing it manually is actually very likely to yield slower program.

@NieDzejkob sometimes some website make it mandatory to have an "(in)security question". You are right though, it is actually a second password so it ought to be as secure as the password - if not more, since you tend not to change it as often. Some websites probably found out I had a pet named "ahPuSei8eenaiYe0zei9iJee".

Splitting water into hydrogen and oxygen requires the exact same amount of energy you get back when you burn it back into water. So to generate, say 20MW in the engine, you must provide 20MW to the water-splitting device.

So… such a loop can built in a perfect world with no heat losses, provided you use 100% of the generated energy to split water back, leaving you with exactly 0W for thrust. If you extract any energy, you no longer have enough to split water.

@Mike.C.Ford …so… the answer is wrong then? The whole point of the Schrödinger's cat thought experiment was for Shcrödinger to show why using the Copenhagen interpretation of quantum mechanics on non-quantic objects is stupid. He built this cat story to make a reductio ad absurdum point. The full story by Schrödinger concludes by explaining a cat cannot be both dead and alive, so the Copenhagen interpretation won't work on non-quantic objects.
