Hypothesis: The "it's not X, it's Y" pattern that LLMs are so fond of outputting can be traced back to a single, very prevalent phrase in the training data:

A screen capture of a commercial for DiGiorno Pizza, reading "It's not delivery... It's DiGiorno."

If I were FTC Commissioner, I would mandate that all popups with a "Maybe later" button must also have a prominent "Never ask me again" button.

Very curious to hear the detailed postmortem on Anthropic model failures this morning will be. Personally, I saw effects on the public Anthropic endpoints, but _also_ on Azure, AWS, and GCP, which is not typical outage behavior for model endpoints. Suggestive of a big configuration change, imo.

Hot take: .gitignore should be for things _specific to that repository_. General files that should always be ignored go in your user-level .gitignore.

Controversial take: making your coding agent a coauthor on your commits is harmful in the long run. It invites too much abdication of responsibility.

✈️ Off to NYC. This week's trip and work is sponsored by the John T. and Catherine D. MacArthur Foundation, committed to building a more just, verdant, and peaceful world. (I've always wanted to say that!)

Google's most advanced Gemini model: "I'm sorry, but I can't generate images of copyrighted characters." Also Google's most advanced Gemini model:

A screenshot of Google Gemini generating an image of what appears to be Mario from the Nintendo franchise punching a question-mark block. The prompt is "Create an image in the bright, color-saturated style of a video game of an Italian plumber in a red and blue outfit. The plumber is hitting a large cube with a question mark from below with an upraised fist. A mushroom emerges from the top of the cube."

This lil guy was supposed to be at 40 μF, but was down to 11 μF and that's why my upstairs had no AC today. Fortunately, we keep spares around for just this reason. 😄

Smaug quarantined the cursed gold of Erebor for 170 years, blocked Sauron from claiming the North, triggered the chain of events that found the One Ring, and gutted the goblin armies right before the War of the Ring. In effect, the dragon is the savior of the Third Age. In this essay, I will

My finance students got me what is among the greatest possible gifts for a teacher to get: eight boxes of The Good Chalk. Thank you Amanda, Amir, Anjith, Delilah, Dimitri, Freyr, Irma, James, Jeremy, Juliet, Kavan, Kevin, Laxmi, Stavros, Steve, and Thor, and good luck on your future careers!

Had to go to NYC to get the good Virginian ramps because I missed all the local ones. It may be, perhaps, the perfect vegetable. I could eat these by the barrel.

A picture of two ramps laying in a shallow bowl. Ramps are green, leafy vegetables with red stalks and a thin bulb, resembling a cross between garlic and onion in flavor.

Ready for the consequences of pushing all my weekly/biweekly meetings into as few days as possible. Hoping it stays dry outside so I can go for a stroll for at least a few of these.

Remember when people said the grid "couldn't handle" EVs? I guess bolting a data center on the side of every house is fine, though.

Screenshot of a post from "Exec Sum" (@exec_sum) on X.com. The text reads: "BREAKING: Nvidia and PulteGroup are partnering with startup Span to install mini data centers on the walls of new homes. Each unit packs 16 Nvidia Blackwell GPUs, 4 AMD EPYC CPUs, and 3TB of RAM — and taps unused home electrical capacity to run AI inference workloads." Below the text are two side-by-side photos: on the left, the exterior corner of a modern dark-sided house with two slim white wall-mounted units and a low boxy unit installed on the ground beside landscaped shrubs; on the right, a portrait of a man with short dark hair and a beard, arms crossed, wearing a charcoal V-neck sweater over a checked collared shirt, standing against a plain gray backdrop.
