Depending on how long ago it was, it could've been John Madden. Not a tycoon, but the first guy that pops into my head re: sports who refused to fly.
Didn't he famously have a very fancy bus?

Hmm I copy pasted directly from the article header and it didn't exceed the char limit. Updated, thanks for the heads-up.
I think it's not about the character limit. In a title like "We did X for the first time using framework Y", the phrase "for the first time" wouldn't add anything so it gets auto-edited out - but here it's needed.
Correct title is "Immigrant Population in U.S. Drops for the First Time in Decades" - is there something automatically editing the titles to remove certain phrases?

I’ve never seen a Series K before. I wonder how their cap table looks like.
If you Google "Series K investment" basically all the hits are about this. Same applies for J and I - you have to get back to H before you start seeing anyone else.
In college I always took notes in class then I would rewrite them and at the same time organize them. In my study groups people would always copy my re-written notes. There was certainly something there aiding in learning, more than just sending a document of notes and just reading it.
Sometimes I'd just take one set of notes and then not look at them after.
So then I got the brilliant idea to not take notes, since I wasn't looking at them!
It turned out that the act of taking the notes was fixing the material in my head such that I didn't need the notes to refer back to.
Yeah I was gonna say the same thing. So in a base-6 counting system primes must be very intuitive to spot. Although also expanding it out to base-12 shows the primes always fall into 4 specific rows.
It's similar to how in base 10 all primes must have last digit 1, 3, 7, or 9. But it woks slightly better in base 6 because fewer numbers are candidates (2/6 ~ 33% instead of 4/10 = 40%)
>There are more prime numbers than there are squares of integers.
all integers have a square, while not all integers are prime.
in any given span, you'll see more primes than squares, however.
more dense?
For example, the number of primes less than n is around n/log(n) while the number of squares less than n is around sqrt(n), which is much smaller.
Nice patterns are reveals when cols is prime.
Not so much that cols is prime as that cols+1 or cols-1 has lots of factors - see for example 25 or 91 or 119. But it does seem like numbers adjacent to primes have a lot of factors.
Perhaps explore plotting the Ulam spiral too? https://en.wikipedia.org/wiki/Ulam_spiral
Of course the pressing question is, if this is the start field for a Conway game-of-life, do any interesting patterns evolve?
It would be fun to brute-force a few starting grid sizes and seeing how long the game continues. Games that last more than a few steps can be set aside for human evaluation.
Because if it turns out that some particular smallish grid or spiral of primes causes something interesting to happen in game-of-life, then you can imagine HN melting down!?
Seconding the Ulam spiral. My first thought was "why can't I see the diagonals?" because I expected it to be the Ulam spiral.
I found this claim unbelievable, but it is mostly true. It isn't quite the whole egg, it is just the yolk. But that's still a very large cell!

It's analogous to the mammalian egg, but a lot bigger. (And IIRC the egg is the largest cell in humans.)
