If you can influence the error rate of a disk drive by yelling at it (https://www.youtube.com/watch?v=tDacjrSCeq4), then can't you measure earthquakes with a long optical fiber
No, because you don't know where in the cable the event occurs. One possibility would be to dedicate a fiber to these measurements, using OTDR (optical time domain reflectometry) to detect an event. But this would only work on cables without repeaters. Given that these microphonic effects are most likely increadibly weak, and the attenuation incredibly high it probably wouldn't work.
Long story short: these cables were meant for no other purpose than transmitting data -a task daunting enough in itself- and their only "interest" is that they are more or less situated around the area where someone would like to have something else installed.
In terms of rote economics, implementing these sensors into the cable system would be “peanuts” compared to what telecom consortiums are already paying to lay cables across oceans. According to the October ITU report, adding these sensors would add an additional 5-10 percent to the cost of laying a new cable, which generally cost hundreds of millions of dollars.
5-10 percent of hundreds of millions of dollars is not peanuts to me. While this may be an interesting idea, I can imagine that telecom operators are not enthusiastic to implement something this costly, which adds complexity to their installation with limited benefit for themselves.

I am beginning to understand the etymology of your username.
(obvious) Jokes aside, this is a very important remark. We carry a lot of bacteria around. More specifically, our own body cells are outnumbered by a factor of 10 by bacteria. It is clear that these have a tremendous impact on out metabolism, resistance against disease, body odor etc. I am not an expert, but can imagine that in Dawkins' "extended fenotype" style, gut bacteria may not only be influenced by one's diet (vegetarian/carnivorous/fatty/sugar/...), but may in turn influence our own appetite using hormones or whatever. At that point it becomes a positive feedback system. (again, this is just wild speculation from a non-expert)
What he actually says is that he cut down his power consumption so drastically that he is self-reliant with a small solar panel and some batteries. Using only low voltage devices and consuming a small power, indeed there is no need to convert to AC.
However, his biggest achievement is being self-reliant (insofar this is true...) and has nothing to do with AC/DC conversion. AC is being used, mainly because it is easy (and highly efficient!) to change its voltage using transformers. There are some other advantages related to shutting down arcs, and disadvantages related to skin effect, but using transformers is the main one.
For any realistic electrical power consumption the currents at low voltage would be so ridiculously high that very thick conductors would be needed to limit the losses (and fire risk), self-reliant or not. The reasonable thing in that case would be to use an invertor to go to 120/230V AC. The losses would easily be offset by the lower demands on the cabling. It is no coincidence that the power grid and, to a lesser extent, homes operate at high voltage.
That 127.0.0.1 site is nothing but trouble. That's why I redirect it in my HOSTS file to localhost.
Hehe, depends on what you want. I have checked for myself and 127.0.0.1 is full of first class porn.
if you don't have enough data and/or the software model isn't good enough then the hardware won't make much difference
Agreed. This is why they are also assing hardware to record more data. More data = bigger computer = better predictions makes sense to me.
Again, math fails to describe nature very well.
Maths is perfectly capable to describe nature. Insofar as we understand nature (physics), our description uses maths. The problem is in crappy programming. No more, no less.
I know some people won't quite get my point, or they'll say, "But metric is so much easier once you know it!" Really though, metric is only much easier when you're doing math. On a day to day level, most of us don't need to do enough math for it to matter.

There are plenty of reasons (beyond merely operating the vehicle) to need windows
Most of all, the passenger experience would be silimar to a submarine's, except with lots of more stuff to bump in to.
While my statement may also hold for those wealthy leaders of 1800 (thanks for that piece of info, btw), I was referring to today. The people from 1800 are no longer alive and can no longer ponder on this. Judging from your comment, I don't expect you to do so either, and maybe it was poorly formulated. "flaming error" did a better job, and I regret he is not modded higher.
The point I wanted to make, is that one of the reasons why the western world is doing relatively well nowadays, is because we stole from other countries (colonies) in the past and continue to do so today. Let the Chinese pollute their country and buy stuff cheaply. Buy cheap resources from Africa and South America. And feel good about ourselves because injustice is not literally carried out by our own hands. That these things happen is sad. Explicitly saying one "no longer feels guilty" (which, as mentioned, probably never happened before either) is ignorant and imho unfair.
