Brain bug of the last week: I have not seen one person say "Silent Hill Forte" in the wild. I've googled it and seen people saying it there, but that doesn't count. Thank you for your attention.

Introducing the Joel Box, just about done. Little motorized Joel I'll hopefully be able to affix on my TwitchCon badge. I'll also have little Joel pins for anyone that's finds me there!

Very cool! I wonder if this species can be steamed and eaten...

Plain text equations and mathematica notebook crap, in case anyone wants to copy and paste or use it for future reference. My work is not very readable lol.

Maybe a bit ambitious before bed... Still work to be done to get it in terms of a strict quadratic programming problem (remove the "forall"). But this is what it looks like in terms of a_3, b_3, pretty ugly. On the wiki for quadratic programming, this gives Q and c but not sufficient A or b.

Oh yeah this can nerd snipe me, I'll try my hand!

I ordered a couple of small metal prints of some of my sculptures from Craftcloud (IN3DTEC was the printer). Spendy (and don’t forget the extra $30 in tariffs!), but they came out looking pretty darn spectacular!

Two swirly polished steel sculptures, with a pencil for scale. They’re about 1.5”/35mm tall

Closeup on sculpture 1, with tetrahedral symmetry and swirly connections

Sculpture 2, with cubical symmetry and swirls from the vertices to the center

(The code is meant to be bad / tongue in cheek :P)
Other than that it would have to be physics-inspired stuff; hubbard-stratonovich transformation, Fortuin-Kasteleyn, replica trick, Feynman diagrams. Basically all clever ways of finding GF coefs or rewriting GFs in terms of new variables!

Recently have been quite fond of this guy turning any rational generating function into its sequence of coefficients, using the stream processing ideas in the book SICP. It's nice that it's only like 35 lines of js and is totally general.

~shrug~ if it makes sense in the context then sure

I'd love to see this zooming into 1/phi! ;)

Anyone post #math challenges on here? This integral (said to be due to Joseph Bertrand) posted by ChetuyaGamma on the other site hooked me. (I think integrating via contour is consider the coward's way out, but I like the wiggly lines okay?)

integral of ArcTan[x/a]ArcTan[x/b]/x^2 dx from 0 to infinity

He hit me with the retweet it's so over.

Had to pause the latest #3blue1brown video after the 10 seconds to try to solve it myself.
Given an n cube, how many unique connected partial n cubes can we construct out of (n-k) faces? (This is rhetorical, I'm trying it and will try to bumble my way through the computations)
