You can do better than that. Assuming you don't care about portability, it is easy to tell if a disk is USB or not by poking around /sys. Linux also seems to have a notion of "removable disk", as the eject command can te

In practice, as an American, we have a custom of paying merchants to cheat us out of a penny. As in, if a charge come out to $4.99, we hand the cashier a $5 bill and a penny, with the expectation of not receiving change. We also have leave-

We do require sattalites to have an end of life plan, that either safely deorbits, or moves to a graveyard orbit. The Outer Space Treaty is a bit vague on this point, but in practice space fairing nations do require that their own launches

Not all sliced bread. The bakery at my grocery store offers all of their breads in sliced and non-sliced forms. I'm sure they put in some type of preservative, as it lasts longer than when I bake bread, but it lasts no where near as lo

That is not Europe's energy problem today. Their current problem is that a significant amount of their energy infrastructure relies on continuous imports; but a major exported has decided to stop selling to them for reasons that have n

The Shockley–Queisser ceiling describes the limit of energy per unit area. It says nothing about the efficiency in terms of energy per unit money.

Taking the articles figure of 77,000 kWh per year per person. Lets call it 100,000 (10^5) kWh per year per person and a population of 10 billion (10^10) people, we are looking at 10^15 kWh/year of energy, which is about 10^14 watts. Ea

Energy is not sufficient to do stuff. You still need a thing to convert that energy into something useful, and those things cost money as well. Taking refrigeration as an example; using my local home improvement store as an example (which i

Is there any reason not to do Level 2. Every building has either 240 split phase or 208 3 phase (at least in the US). If you are going to add a new circut and wiring to support charging, why not use a full power circuit?

It is easy to be fast if you are willing to ship broken software. The Linux solution was broken. People knew the Linux solution was broken when it was shipped. The Linux developers knew what a non broken solution would be because the CPU ma

Installing a 240V or 208V outlet should be just as simple, although the result will be less convenient for anything someone might want to do with a power outlet in a parking lot. Although, if you are wiring a 240/208 circut, you should

It's a capital expense to make the upgrade, and a political question of what should be done to require/encourage it. All you really need is a standard 120V outdoor outlet at each spot. Consider that for every one or two cars that

And? This has always been the plan. We are migrating to electric because of the harm gas does to the environment, not consumer preference. Just like the migration away from leaded gassoline, or chlorofluorocarbons was done by regulation, no

It forces git to intereperet what comes after as paths. Normally this is not needed, but occasionally you get a filename that causes ambiguity. For instance, "git checkout test.c" will check out the file test.c unless you happen t

Does boiling water actually help with chemical contamination. The main benefit is killing microorganisms. The heat can also destroy some toxins, but as far as I am aware PFAS stick around at boiling temperatures.

In theory, the challenge to a default judgement would be due process based. In practice, this particular case is practically a textbook example of when due process is appropriate, so I don't see how such a claim could possibly succeed.

If we assume general relativity is correct, then singularities are an unavoidable result of black holes. The math simply does not allow for such a large density to not form a singularity. Having said that, we know GR is not correct, as it f

In some sense, the field of classical cryptography has never matured. Outside of some very simple and limited applicability systems (e.g. one time pads), the field has never really moved beyond 'propose a cipher, and act as if it is se
