@Floppy is someone who was incorrectly declared dead 'undead'?

@ccppurcell @11011110 well, that got me to look at it.

Is someone chopping onions?

I watched this nice talk about documenting code, yesterday: https://peertube.social/videos/watch/8f27a614-aa63-4811-af6a-b9e11effc399

Choose a random graph with countably infinite vertices by flipping a coin to decide whether to include each edge. Or, construct a graph with binary numbers as vertices, with an edge \(x\)—\(y\) when \(x<y\) and the \(x\)th bit of \(y\) is one. Or, construct a graph on primes congruent to 1 mod 4, with an edge when one is a quadratic residue mod the other. They're all the same graph, the Rado graph (https://en.wikipedia.org/wiki/Rado_graph)! It has many other amazing properties. Now a Good Article on Wikipedia.

@JordiGH I think they're auto-spamming lots of people. The emails are usually worded in a way that makes it look like they're not specifically targetting Mastodon. I'd be surprised if a human with any kind of influence on the system ever sees your response,

@jc I also do that!

I wrote a bit about a bisection of a triangle's area which, when I read it, made me lower the book and call it a rotten liar. (It wasn't lying.) The thing might be old hat to you, but it startled *me*.

(I have a follow-up post to it scheduled to post later today.)

@nebusj I enjoyed reading that, and I'm going to try it. Morley's theorem is bad voodoo, true.

@halcy subject line: "eliciting posteriors"

@autumnaterr yes, but it's strictly virtual: http://nice-calculator.glitch.me/

I've never had any luck with soldering seven segment displays. Maybe one day!

@autumnaterr I made my own calculator recently, so the way they work was on my mind

@autumnaterr and tonnes of people in offices or non-automated shops have a basic add-subtract-multiply-divide calculator hanging about

@autumnaterr well, casio scientific calculators are what almost everyone uses. The ones they use these days can compute all sorts of statistics and do some light algebra, but the input method is the same.
