That sounds circular and crazy; he needs an EIN to be safe, but according to you he doesn't need one because of [unrelated reasons].

No, really man. Contractors with no employees should be giving out an EIN, not a SSN. They are free and you're allowed to have them. And they cannot be used for credit applications, only for tax reporting.

"and a handful of other sensory information" renders your attempted correction incorrect. That is a different thing.

And you still can't "hear" the location. You simply infer it, and are often correct.

Using only ears, you absolutely cannot. And using other sensory information, you usually already have it narrowed down; so you think you hear where it came from, but you didn't. You saw where it came from, or where it didn't.

I don't mind this. A client with important servers is running a different OS. Nearly any other OS actually, there are a wide variety of quality choices on a server these days.

Auto update shields the admin from being responsible for MS screwups. Those are MS's fault, not the admin, and are related to the customers choice of technologies. If a client starts to complain about the problems, that is a premium time to discuss the extra charges for fixing the screwup. That shifts their focus onto MS, because if they get mad and call somebody else, they'll find out, "yeah, everybody with windows is dealing with that one right now."

So just leave auto-update on, and if there are hiccups now and then... well, windows gets the hiccups regularly, it is not a special thing associated with updates. Even worse than the broken updates are the long list gaping in-the-wild security holes that that update probably patches.

The purpose of the thought experiment is not the engineering analysis that Feynman did, as interesting as that also is. Nor was the discussion here about if it is feasible to build with human understanding. And nobody is talking about reversing the laws. The physical "laws" already allow for energy changes to be reversible. And people are waving their hands a lot about thermodynamics without, I think, even considering the thought experiment. People remember, "a perpetual motion machine is impossible," then they try to apply that instead of the law. Of course if the advanced aliens build an isolated system, a perfect Dyson Sphere, then the conservation of energy already means you won't have losses. The initial premise determines all of these interesting side effects.

The problem with Maxwell's Demon is that the demon is an engine, doing work and adding energy to the system. That is true even if the demon is "magic." Heck, gravity is just magic, as far as we know; luckily the laws of physics don't get involved in "why."

If you didn't focus your attention on it, then you did not receive any information from it. You're claiming it doesn't work. But it does work; the drivers attention will focus on the screen, wherever you put that screen. It is part of the basic premise of displaying information.

"Use" means to convert it to a different form. That is all it means, that is all it ever means. In an isolated system, there is no loss. You seem to think heat is somehow different than everything else, but the laws of thermodynamics apply to heat as well. Everything is conserved, there is no requirement for something to escape. Calling an isolated system a "perpetual motion machine" is to misunderstand the whole concept; to misunderstand why even a perpetual motion machine is impossible. Of course the Universe itself might be a "perpetual motion machine." The whole problem with perpetual motion is that it is not an isolated system. It will interact with the world around it, indeed it has to in order for you to know it is "working," and generally it is presumed to be doing some work external to the device. So by being a machine of some sort, it has to lose energy.
In the version of the Dyson Sphere thought experiment that was being discussed, you have an isolated system. All the work is being done inside the device. No work is being done outside the device. So the exact same principle of conservation of energy that says that a "perpetual motion machine" is impossible, also says there is no energy gains or losses inside an isolated system.
And no, you're not collecting anything; whatever is collected was collected during the construction of the Dyson Sphere. Presumably they torched up a few gas giants for construction power.

Not only can we not find the dark matter or dark energy...

Look. We just recently mapped the Earth's radiation belts. Oops, they did not match prediction. At all. Not even the right number of belts.

Voyager is out exploring the Solar System's heliopause. Ooops, not as predicted.

That is the recent actual experimental work that has come out of cosmology lately. The rest of it is a lot of hand-waving using edge data points, at scales where nothing can be verified.

Compare that to the work that actual physicists do at the subatomic level, where experiments usually match predictions to insane numbers of decimal points. That is what real science looks like.

This stuff about, "oh we got our own neighborhood totally wrong, we don't understand how the solar system formed well enough to predict the heliopause, we don't understand our own planet well enough to predict the radiation belts, but when it comes to the really large measurements using edge data, we're really right-on, and sure of it." It is just total crap, at the flat-Earth level. Background radiation is the ultimate edge data; if Big Bang is true, it would be like God; an un-provabable hypothesis that science should ignore in preference of logical positivism. If it is true, we can't prove it, because we'll never have a sensor where we can test it on both sides of the value we want to measure. We can never calibrate a sensor, so we just can't know.

Maybe old photons just turn redder and redder and then die, and the cosmic background radiation is a giant field of dead photons that all average the same age because they then fade away after another n years. Maybe there is more than one cause of redshift; the cause we can verify at very tiny scales, and another one at cosmic scales that we haven't even tested for yet, or had the chance to test for yet. Nobody in academia wants to ask about that, because if they start the experiment now, they won't be the ones to write the papers in a few million years when the answer comes in.

Edge data tells us nothing. That the "early Universe" is presumed to have simpler laws of physics reminds of me something. The way that trees on the horizon at the edge of my vision appear simpler and simpler; and yet retain all their symmetries.

Allow me to paraphrase your comment.

"My subjective assessment is different than yours, but I'm so insecure about not being able to prove subjectives that I'm going to call your viewpoint names."

Was Feynman a better showman than the other people who also came up with working math for QED? Yes.

Einstein was also a great showman, who is widely believed to have stolen some of his theories from his first wife. Einstein is legendary as a showman, if you actually are interested in these sorts of non-science details. As a lover of history, I find there is a lot to be learned both from the "great minds" of the past, and from the process of deciding what to remember and hold up as "great," and what to ignore. All of the names remembered are the great Showmen, and they are only maybe 5% (throwing numbers at the wall) of the equally-great minds of their time that were actively engaged in the same fields.

However, none of that matters. Arguing that a subjective opinion is somehow wrong, that is provably wrong. You're totally wrong. Totally. It is provable, too, simply by examining the nature of "opinion." Since this story is about science, not philosophy, I'll leave that as exercise for you to do on your own.

Your subjective view might be great, it might meet your needs, it might be "true" based on your standards. But claiming it is better, or more correct, than somebody else's subjective view, that is guaranteed to be wrong . It is also anti-social and narcissistic.

Wow, the self-important, self-certain ignorance is really rank.

You seem to be conflating a bunch of different things, then waving your hands and shouting "impossible." Impossible is the idiot's way of saying, "I don't know the answer."

If you have heat, you have useful energy. Period.

Entropy goes up in an isolated system that contains irreversible processes. But no process is irreversible, given the precondition of an intelligent race with advanced technology. The only reason entropy "has to" go up in the standard thought experiment is that the thought experiment is set up so that there is not intelligent beings inside the isolated system making changes; and the system contains irreversible processes. But on process is irreversible at a basic level. It is just that many processes aren't naturally reversed; there is no mechanism for reversal. With intelligent being and technology, you can not longer make that assumption. Easy peasy.

It is better to give than to lend, and it costs about the same.
