> To be fair it was usually small, inconsequential things

I’ve always wondered about this bit:

“One nation, under God, with liberty and justice for all”

The "under God" was added after the fact: https://en.wikipedia.org/wiki/Pledge_of_Allegiance#Addition_...

The liberty and justice parts are questionable too.

I'm sure you could make the argument using some definition of best. Perhaps best in it's impact via software created in it rather than the language itself. Although then I think C would win over C++ because of Linux.

I'm imagining a slightly tongue in cheek 'best' alongside an implication of subjectivity. But given this was a highschool teacher I wouldn't be surprised if it was instead a multi choice test question with a single "correct" answer? Which of course would be ridiculous.

"make the argument using some definition of best"

I won't take the bait to dive into that discussion! ;)

Luckily she never tested us on it, I think she was understandably biased from working in C++ in an earlier job.

Last one is correct, actually.

> The only major one I remember is that water is conductive by itself.

Most people don't know that pure water is an insulator.

However, in a practical sense that's ok since it's unlikely any pool of water is pure.

So for safety reasons involving electricity, one has to assume that any pool of water can conduct electricity.

My uncle works for a water treatment company. Medical manufacturers often come to him saying his equipment is off because they open the test port ran the pure water into a clean glass and it tested below specs. He then has to explain that in the 30 seconds between opening the valve and the test the water absorbed enough impurities to fail the spec. The input water was fine.

Another interesting anecdote about water treatment facilities is the situation in Asia.

For example, Jakarta has a water treatment facility, but every tourist gets stomach illness there. The reason is that industrial facilities siphon off the treated water, and by the time homes and hotels get any, it's untreated.

To give you an idea how bad it is, tourists generally don't drink tap water, but they still get ill from the washed dishes, or not closing their mouth in the shower.

(Bali can always find money for road construction (they built two impressive underpasses in the last 6 years), but never enough for a power generation plant, so has continual brownouts.)

How does that work? If the water is being used by the industrial facilities then the water pressure/flow rate would drop.

Unless the facilities are adding dirty water to the pipe to push pressure back up after they remove it? But even then, unless they routed the pipe from the water treatment facility to the industry first, only the areas downstream from the industry would be affected.

More likely is that the water is not being adequately treated and/or that the infrastructure is not built/maintained and the pipes are leaky.

My guess would be that the treatment is to minimum spec and that there are leaky pipes which allow for contamination. It is hard to maintain pumped water pressure if there are brownouts.

I would guess that they have a treatment system that isn't big enough, and they pump in unfiltered water to make up the difference when the treatment plant cannot keep up.

Even in the US I know of cities that have had boil orders because the treatment plant couldn't keep up and they pumped in untreated water. The cases I know of the unfiltered water made it in via weather events (the treatment plant is on the river and it flooded. Also a case where the power went out on a big surge and so they hardwired the pumps to the well bypassing treatment until the treatment controller boards could be replaced.)
