+1 for Zweig’s Fantastic Night
These are literally the two most depressing books my geographical region has ever produced and that’s a very competitive market. Why not read instead — or to balance and supplement — Zweig’s Fantastic Night (still in his prime, lush and startling) and instead of Roth, Szerb’s mythic, desperate, erotic Journey by Moonlight on how that world fell apart.

It seems insane, completely indefensible to me, to say the code was never the hard part. Learning how to code at a high level would take you all the way to senior software engineer/architect. The only people saying this simply have no idea how things really worked in software

A dump of the archive of all the Smalltalk Report from 1991 to 1996. There are some interesting articles that cannot be found on the web: github.com/Ducasse/Smalltalk…

Phil Williams. My boss’ boss at Apple. Surfer dude, feet on his desk. We guys asked each other over lunch “What does Phil do all day?” Then Phil left. “Oh.” I’m sorry, Phil.

One of the very best illustrations of the nature of social media is the number of accounts responding to disagree about the understanding of gravitation with *Edward Witten*. (Whose nail clippings probably know more math and physics than the accounts.)
American physicist Edward Witten explains why it wasn’t until Einstein's work that we fully understand the reason behind the inverse square law, and why it's specifically a square rather than some arbitrary decimal 1 / distance² vs. 1 / distance¹·⁷⁴⁸²²⋅⋅⋅

There's a fantastic paper about this called The Discoveries of Continuations by John Reynolds. homepages.inf.ed.ac.uk/wadle…
whoever invented callbacks, continuations, generators, whatever you want to call them. that person was amazing. they deserve the world

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.

Been there, done that. @orzelc is one of my people.
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'.
