Yeah but is anything really that important in the long run? We’re all just weird monkeys who are all going to die eventually. If President Trump really wants to do something, why not just let him do it and stop complaining? Do you really want to make President Trump sad?
Right but how do you expose your state machine and epoll logic to callers? As a blocking function? As a function that accepts continuations and runs on its own thread? Or with no interface such that anyone who wants to interoperate with you has to modify your state machine?
Most travel happens between cities that are close together, and Chicago has always been the larger gateway to the rest of the nation and the world.
The French urban areas on the TGV aren’t very big; Montpelier, for example, has a total of 600,000 people in its metro area, which is roughly the same size as Toledo, OH or Wichita, KS.
Montpellier probably gets more tourism than Toledo though. And most people taking the train to Paris are probably not doing it so they can fly somewhere else.
And yeah, there would be a fair amount of demand just to Chicago the same way there is a fair amount of demand to Paris, in that they’re both the regional powerhouses with finance, HQs, etc.
What we call "magenta" is the sensation of both red and blue color-sensitive cells in the eye being excited at the same time. There's no single wavelength that produces this effect (unlike e.g. yellow). The closes you can get is violet, which looks faint to the eye.
A rainbow gives you both red and blue; mute everything else, and you'll get magenta. That's what magenta pigments do when illuminated by white light (which is a rainbow scrambled).
The interference is a wavelength too. Maybe not pure but it is one. Afaik they cannot be interpreted as two separate wavelengths and then “brain combined” when the aperture (the retina) is so small.
I haven't heard of a wavelength of 2 frequencies merged. It is like saying what is the wavelength if you tune to 2 radio stations with 2 radios (assume silent transmition for simplicity). There are 2 wavelengths.

No, any wave has a wavelength. You can add sin(3x) to sin(2x) and the resulting wave is a perfect fifth. Its wavelength is determined by its components; since sin(2x) has a wavelength of π and sin(3x) has one of 2π/3, the combined wave will have one of 2π.
The difference is that sin(2x) and sin(3x) are both sine waves, while their sum is not. There is no such thing as a pure tone of two merged frequencies, but there are many possible waves at any given frequency that aren't pure tones.
Here's a nice visualization of color perception (there are more modern ones, but we used the 1931 color space when I was working in the field). The horseshoe shape on the outside is the single wavelength colors.
