Six weeks ago, my mom broke her foot on a hike during our family reunion. Two days ago, my dad also broke his foot when we were out walking together on a trip. Man, I’m bad luck!

It’s my 33rd Birthday!🎂

Totally. It’s like saying, “here are the Hodgkin-Huxley equations — see, we perfectly understand the brain.”

These are good reasons, but if you were to reconsider:
- this is my favorite explanation: stopa.io/post/269
- GIT is the proof of the inevitability of the halting problem, which is still quite practical, eg: github.com/cubed-dev/cu...
- GIT shows the real limits of AI, which is relevant as ever

Will you have a chapter on Godel’s Incompleteness Theorem by any chance? That would be amazing!

I love papers like these that answer a cross cutting concern when modeling in a domain. These optimizers are interesting and I hope to incorporate these methods into my work.

I used to work on this team, they’re doing amazing work in ML and weather!

Having AI crammed down our throats is bullshit, but machine learning has some real uses in science. This awesome page shows experimental cyclone track forecasts from Google DeepMind and Google Research's AI weather models, along with forecasts from ECMWF. 😍

A dark-themed weather tracking map from Google Weather Lab: Cyclones (Preview) showing hurricane/cyclone models in the Atlantic Ocean as of Friday, September 19, 2025, at 08:00. The map includes ensemble forecast tracks and storm markers extending from the mid-Atlantic toward Western Europe. Multiple colorful lines (green, orange, blue, purple, yellow) represent different storm model ensembles and possible tracks, with clusters of paths pointing toward Ireland, the United Kingdom, France, Spain, and Portugal. The cyclone originated east of the Caribbean, with its projected paths fanning northeastward across the Atlantic. Colored circles mark storm intensity along the tracks, numbered (e.g., 1, 2, 6) corresponding to categories. A second storm is visible off the Pacific coast of Mexico with clustered ensemble markers. The left panel lists model options (Observed, Our experimental model, WeatherNext Gen, WeatherNext Graph, ECMWF ENS, ECMWF HRES), a legend for storm markers, tracks, ensemble tracks, cones, and wind speed colors. At the bottom, sliders indicate initialization time (Fri, Sep 19, 2025, 08:00) and lead time (+6 days, Fri, Sep 26, 2025, 02:00). The background map highlights North America, the Atlantic Ocean, Western Europe, and parts of Africa.

What else better complements a smash burger?

This works for generating image programs. What if it could be used to generate audio (music) programs? Say, for strudel.cc, for example.

I just finished the paper. What an excellent read! Data Science is a commons built on frictionless reproducibility. We have hit the repro singularity, and we’re far from AGI. Scaling focus is the AI hegemony privatizing the commons for their gain. The future of data science is shared, better ideas.

I’m having a great time digesting “Data Science at the Singularity” and thinking about data products

How much compute do you have access to? May I suggest a few interesting modeling projects?
