Mathematically incorrect footballs: This episode of Bing gets the panel shapes correct but falls at the final hurdle. Instead of colouring the 12 pentagons black, they colour 2 of the pentagons and 6 of the hexagons.

The bot says it's the hardest one we've seen so far, requiring 16 walls! https://mathstodon.xyz/@OptimalCeltixBot/113869069741849948 But it took me even more than that.

I completed #Celtix 228 using 19 walls.

Got two Roses Orange Creams inside the same wrapper. I think this is the equivalent of a double-yolk egg.

So in HoTT everything automatically respects the principle of equivalence, and it's impossible to write down something that doesn't. Whereas in ZFC we have the ability to do evil and we have to choose not to. Kinda feels like a snake got someone to eat an apple.

I've installed #NixOS on my daily driver, and I'm really loving it so far. The most pleasing thing is that you can't fuck it up. With Debian I'd try a hundred things to get my GPU working, and then I'd worry that the ninety nine bad attempts had left my system in a weird state. With NixOS the entire state of the system is defined from a single file, so once you've found the right config then the system will always be correct! And finding the right config was actually easier too.

A funny paper from 1979: 'Why We Should Not Make Mean Log of Wealth Big Though Years to Act Are Long' https://citeseerx.ist.psu.edu/document?repid=rep1&type=pdf&doi=8d9c06de772124caff8179d83d31fc9f7ffe5ed7

This is about the Kelly Criterion, which is a suggestion for how much you should bet on a risky investment with positive expected value. There was a heated debate about whether this criterion was only useful when your utility was logarithmic in money, or if it had broader applicability. The argument got so bad that Samuelson thought his opponents needed everything explained in words of one syllable!

Not only is this very patronising, he also screws it up by using two syllable words in a couple of places. But I still think he's right about the Kelly Criterion.

Thinking of making a Rubik's Cube with piece colours interpolating between the centre colours (which would be black, white, red, green, blue and yellow). Still working on getting the colours evenly spaced though.

@mscroggs I made three guesses on your advent calendar yesterday, but now it's still telling me to 'Try again tomorrow...'. How does the cooldown timer work?

Are there any interesting integer sequences that contain every finite string of natural numbers as a contiguous substring? In particular ones that try to do so as efficiently as possible? Like the index at which a string first appears isn't too much greater than the number of 'simpler' strings, in some sense.

Is there anything interesting to say about the combinatorial species given by the identity core(FinSet) → core(FinSet), except acting by an outer automorphism on S₆?

Is there a shape like a prism except with a hat tile at one end and a turtle tile at the other? Ideally the prisms themselves would also fit together.
