Seconds are clearly defined by one specific caesium-133 transition

The second […] is defined by taking the fixed numerical value of the caesium frequency, ΔνCs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be 9192631770 when expressed in the unit Hz, which is equal to s−1

It’s some right winger platform

Unless you get one of the day’s 10’000, it’ll be recognised by any tech people.

With color spaces we’re talking about standards like sRGB, Rec.2020 and many more. Wikipedia Article

If a video comes with information on the color space it uses, the video player and compositor can now do a more source accurate mapping to your screen than before.

If you also have an ICC profile for your monitor, you’ll get the most out of your panel now. Without that, the compositor will assume an sRGB calibration (when not using HDR) and do its best to map a higher definition video to that.

That’s why you shouldn’t Frankenstein it

I use nginx, mainly because that’s what I learned first and see no reason to replace that.

It depends on the registrar. Some just assume the information you provided is valid.
Infomaniak apparently wants to verify your info, though they also offered verification through credit card when I signed up.

Next Proton if they enable full Wayland support

This is pretty much an ad and OP might be the one who wrote the article.

If you want a known good program to rip Blu-Ray disks, MakeMKV is probably the program you’d want to use.

I know of FairEmail, Niagara Launcher, FolderSync and Symfonium (if you DM the dev) which offer alternate payment methods.
