True it is…

Yes at exactly 0K and without quantumechanics…

Yoy can filter out frequencies in the rainbow spectra in a way that it looks like any color…

There is no such thing as a mono wavelength color. There are only spectral densities. Or in other words electromagnetic radiation / photons distributed over some energy.

Naah… Its just confusing spectra with perception… We may only perceive 72% of the spectra… But the rainbow it self has all the colors…

Well there is wavelength and intensity, an all together it is called a spectrum. No need for a third parameter. Also there are mor than 100% of all colors in there, as a quick check on Wikipedia would reveal…

Interested as well. There is a review on the Aliexpress page stating that OPNsense via Proxmox works fine:

I have to admit, that this might be true the very most cases. But there are more reasons why servers still have a video-port.

Cool, So actually something one could build out of anything with an USB, Ethernet port. But not sure how to add the Display receiver… They using a RPi for this as well. I don’t like that it occupies Video connector. Lots of systems only have a single one

what kind of server could we get for 100$? 500$? 1,000$?

And how long? Days, Months…?
