You’re “aging yourself” by naming Mike Trout? Oh my… Willie Mays Hayes. Kirby Puckett. Bernie Williams.

Astronomical spring and meteorological spring are important, of course, but tomorrow is the most important day of March: sartorial spring, when Prof. Wallingford flips the bit and switches into shorts for the year.

i am pretty sure every song i have ever written was inspired by “boys of summer”. a total masterpiece.
I'd like to think a lyric in @mattnathanson's "Still" was inspired by one in Don Henley's "Boys of Summer." I want to believe every fan of the power of words can build on something great to which we've been exposed. It would affirm there are endless possibilities out there...

This is the dream: train an LLM on the 20 year cache of the session notes, assignments, and readings I've created for my classes, then use it to generate lectures, talks, and presentations. I'll replace myself and get out my hammock. gocomics.com/doonesbury/2026…

I have a post-it note on my desktop on which I record 2FA codes that are palindromes, fun patterns, or cool numbers. It's an unusual affectation that gives me a little bit of pleasure.
I am oddly pleased when 2FA acts me to input numbers that I recognize to have nice numerical properties, like 496.

Replying to @QuantumAephraim
I decided to leave it off, but still spent the whole morning getting the solution to work out correctly, because I'm a huge dork.

This works just as well, maybe better, if we replace 'family' with 'academic community'.

Back in grad school, I spent more than a few hours discussing the Chinese room argument.

Started a new blog - 'American Innocence' - about my new life in America, my observations about culture, politics, way of life here. In my first post I ask: if tragedies are so hard to watch because we feel a lot of it is avoidable why don't we have the same defenses in politics?

RIP to Bill Atkinson, one of the greatest programmers who ever lived. At Apple he created MacPaint, QuickDraw, HyperCard and was a critical part of making the Macintosh magic. He co-founded General Magic - go watch that documentary.

I hadn't heard this song in a while. This lyric stood out today: Well I'm heavenly blessed And worldly wise I'm a peeping Tom techie With x-ray eyes Timbuk 3 - The Future's So Bright youtube.com/watch?v=8qrriKcw…

I participated in an interesting exercise with the head of a university mathematics department once Grad students were brought in and asked what things they would like changed in the department. They made many thoughtful observations Afterward, the Head complained extensively that these problems were rather trivial. Indeed, they were - for him. But not for the students He then spent much of the next two days complaining about things that would have been easy for his Dean or other superiors to change, but which were difficult or impossible for him Related: I once talked to the leading Anglican Archbishop in Australian, who said that from the level of parish priest on up, he always thought the solution to his problems was a promotion. And so it was... except he'd eventually realized that his old problems were always replaced by something far more difficult
