There are 3 separate but apparently indivisible rights brought up in all these articles. Talk about one and you inevitably get drawn into the other two. Defend one and you have to explain your position on the other two. And why those are also right or wrong. 1) The right of Jews to exist and […]

Has anybody checked whether Mr Trump has ever been photographed together with Cthulhu?

This feels like a good essay: "[...] The ordinary forces that tether speech to consequence—social sanction, legal penalty, reputational loss—presuppose a continuous agent whose future can be made worse by what they say. With LLMs, there is no such locus. No body that can be confined or […]

If you need to study some functions but have limited tools you can go a long way assuming everything is linear except at minima/maxima where you assume everything is quadratic. Use this tool in physics and everything looks like a free field or a perturbation thereof. Use this in statistics and […]

Well, my YouTube recap is out and all of my top 5 except the number 1 are now on mastodon. How about it #veritasium - get on board already. Your videos have hit it out of the park this last year; why are you still clinging to toxic social media when there are […] [Original post on mathstodon.xyz]

I think it would be appropriate to share some of my pictures of Ayudha Pooja art for #tilingtuesday

Heads up for the Haskell nerds: functional programming in Real Lifeᵀᴹ https://events.zoom.us/ev/ArYZWTHwHadF1z5rFGmggUTZiZcBn08S86TAk2t3vsjUSgYSY6Mt~AglGQ71j0a2GnjEYXo0S5S9Kwqezl26KKT5Tif00hENXAQMrQLF9fFjFaA

"You're not far left," a buddy says. In a world with fascists controlling every part of the federal government, I'm disinclined to argue with "far left" as a description. At least it clearly distinguishes me from the Nazis.

Same as last week, but with slightly tweaked parameters #tilingtuesday

I keep posting various things for #TilingTuesday that I tinkered with in 2015, so here's a super simple one: Make a regular checker board with the usual two kinds of coloring; but instead of "black" and "white" make each coloring its own checker boards with […] [Original post on mathstodon.xyz]

Done in multiple layers, but not layers that are recognizably stacked on top of each other... #tilingtuesday

I got an email from academia.edu telling me that they turned one of my papers (from 2001) into an AI generated podcast. I don't think it's publicly accessible (because I didn't spring for their 'premium' offer) but it's here in case someone wants to try […]
