I was in Cambridge overnight for the 40 year reunion of our old D&D group. Very tightly scheduled or I would have contacted you :( Next time! I'm also a bit confused about whether you can see this reply as I was notified of it via mastodon and can't find it on bluesky if I go there directly myself.

Density plot of eigenvalues from 1 million 10×10 tridiagonal matrices w/ entries randomly chosen from {0, ±1, ±i, ±10, ±10i, ±20, ±20i}. viewing window is [-48-48i, 48+48i]. The color represents eigenvalue density.

On your phone while grabbing a cart with the other hand? Algorithms are easy. It's the preparatory data munging I hate.

Tip of the day is the start of a question you can ask chatbots:

"Here's my shopping list. Can you regroup it so items that are close together in Trader Joe's end up in the same groups..."

(Don't forget to check the list 'cos it might add chocolate just because it's learnt people like that...)

Eigenvalues for 15 million random 10×10 tridiagonal matrices w/ entries sampled from the discrete set {0, ±1, ±i, ±20, ±20i}. The image shows the density of eigenvalues in the complex plane, with brighter regions indicating higher concentration.

The now viral, incorrect meme that LLMs are just next token predictors is causing so much confusion

I do consider it. A friend has family in the oil business and said that when they dealt with George W Bush before he was president he seemed like a person of normal intelligence. But it seems like such a cynical thing to do. Do people behave like this? Do they hate their electorate this much?

The fact that people like this exist is an insult to anyone anywhere who's ever bothered to learn anything. She has a degree from the University of South Dakota. I can't imagine what kind of institution this is that can produce such ignorance and stupidity.

HASSAN: What is habeas corpus?

NOEM: Habeas corpus is a constitutional right that the president has to be able to remove people from this country

HASSAN: That's incorrect

My daughter just sent me this meme about induction stoves and proof by induction. My work is done.

It’s still hard for me to believe that after so many years of deranged posts like this, we’ve still never had a serious national conversation about this man’s mental health.

I'd pick machines I don't really know as a learning experience: Apple Lisa. Camputers Lynx. Jupiter Ace. Sinclair QL.

n-category theorists can think in ways that we mortal mathematicians cannot. 😔

This is, apparently, an actual commutative diagram excerpted from an actual math paper. (Seen on mathstodon.xyz/@highergeome...)

A commutative diagram with hundreds of objects and arrows, so cluttered and with so much overlap between labels that it is undecipherable.

I'll have whichever one has a BASIC with an inline assembler thank you very much.

I still remember the many ads I saw back then emphasizing that Snowball had 7000 locations which honestly didn't seem like a good feature.

Did you know that there is a shortage of American movies and so now we have to tax foreign movies to ensure American movies get made? Or Republicans are the stupidest people who have ever stumbled across the face of the Earth. One of the two anyway.

The country that locks up more people than anywhere else in the world (because the US loves freedom apparently) can't find enough space to lock people up so it's having to commandeer tourist attractions.

Each point represents one eigenvalue from the spectrum of a random 5×5 matrix with entries from {-1,0,1}. Warmer colors show regions where eigenvalues cluster more densely.

I really feel pity for these people. They really are good at nothing.

It's the wrong units too. I could understand saving $X/yr but an instantaneous saving of $X doesn't entirely make sense.
