How do you even represent HDR colors? I've tried Googling this and I can never really find an answer. Is it basically just eight hex digits instead of six?

Their FAQ says:
> In the U.S., Hexa is approved for flight under FAR Part 103. Hexa conforms to the FAA’s Powered Ultralight classification for which FAA certification is not required or available. The base weight limit for Powered Ultralights is 254 lbs, and Hexa utilizes additional weight allowances for floats and safety equipment.
They may be arguing that the weight of the landing gear counts as floats, which might be true. They may also be wishfully interpreting the FARs and on schedule to learn an expensive lesson in due time. (If so, they wouldn’t be the first startup to pretend the FARs said something other than they did.)
I wouldn't fuck with the FAA, their interpretation of what they say is what's really the law, not what's written in the FAR.
About 30 years ago a pilot in a floatplane was on step as he went under a bridge (he was still in the water, but the floats ride closer to the surface than when it's at near-idle speeds). When the FAA somehow got wind of this, they really put the screws on him because in their interpretation he was flying under the bridge (very illegal), even though he wasn't airborne. Nowhere to my knowledge did the FARs make this distinction between floating and flying. You'd think in a case like this they'd let it go, maybe update the rules to clarify, but they really went after him for it.

That’s interesting. In your context what is “knowing the answer”? To me it seems like they “knew” a given statement was true but they didn’t know how to prove it which makes me wonder how they knew.
The teacher may start off a class with a question like "what is the most efficient way to satisfy this problem given these constraints?" Some people would know the answer immediately but couldn't do a proof for it hardly at all. Others could find a proof in class almost every time, but necer really saw the answer to the problem until they'd sat on it for a while and chewed over it.
Can't really give an example question, it's been well over a decade (closer to two) since I took it.
I have to say re: pipewire that it's one of the few (redhat?) projects of the past 15-20 years that doesn't seem to have generated a ton of hate from users so it must be pretty good all around.

Our discrete mathematics professor leaned heavy on proofs, but also introduced pop quizzes for proofs of algorithms and other mathematical constructs as an experiment that term which sent my anxiety ablaze. You either had the intuition for that particular problem or you didn’t. Studying would not help you that much. The success rate on the quizzes was very low surprising no one.
Classes like this were funny. I often found that people who just knew the answer immediately had a lot of difficulty doing proofs, and the people good at doing proofs usually didn't arrive at the solution very quickly or seem to have an intuitive understanding of the problem at first.
Some people are just wired differently.
Even back to J Edgar Hoover days...
They tried to blackmail MLK to get him to kill himself. A department created originally to fight the mob started acting exactly like it. There's no way a reasonable person's faith in an organization like that could ever be restored.
Imagine the information that isn't public about their misdeeds.
Now, maybe it's just WA state, but if we hit the road for an extended period I'd be reserving spots ahead of time even at places far less popular than, say, Yellowstone.
