TipHey, I’m writing a book about this! I’m actually writing a book about this stuff. It turns out there isn’t a lot of literature on how to do post-training at the level too big for single-GPU laptop-sized hobby projects and requiring enterprise reliability on one hand, but not quite at the scale of multi-team distributed post-training you’d get in foundation labs.
In my previous post, I shared my annual running stats which were generated in R using summary data from Garmin Connect. The code I use to generate these summaries was beginning to get a bit unwieldy, so I have now rebased it into a package.
We refactored the R-universe CI workflows to make it possible to run the exact same workflow from your own GitHub repository. This allows you to test or debug the build and check process on your R package, exactly as it will happen on R-universe, but without actually deploying to https://r-universe.dev.
The stability of spiral galaxies was a foundational motivation to invoke dark matter: a thin disk of self-gravitating stars is unstable unless embedded in a dark matter halo. Modified dynamics can also stabilize galactic disks.

Happy new 2026 everyone! I've had a wonderful journey through Udaipur and the lake palaces, and am currently in Vijayawada exploring my ancestral village for the next few days. I've caught up on some reading, so here are my book thoughts (and podcasts for the first time) from the past year!
How much time do you spend performing various activities? In 2022, I spent 506 hours answering email, or 63 full work-day’s worth of time. At that point, my reading for pleasure had dropped to virtually nil and I just thought: this is not how I want to spend my time. After a radical reorganization of my life and work, I wanted to see how well I have done this year.
Here are the books I read in 2025. My goals for the year were to get some more variety, and I think I managed that.
In this post I’ll use R to recap my running data from 2025. Previous round-ups are here (2021, 2022, 2023, not sure why I didn’t post one for 2024…). I had a goal of running a total distance of 3650 km in 2025.
Sandwich compounds are the colloquial term used for molecules where a metal atom such as an iron dication is “sandwiched” between two carbon-based rings as ligands, most commonly cyclopentadienyl anion (the “bread”) as in e.g. Ferrocene – a molecule first discovered in 1951.
Do it yourself. I don’t mean that as a descriptive phrase. It’s a complete sentence, in the imperative. Do it yourself. Pick up the pencil, pen, stylus, paintbrush, airbrush, mouse, keyboard, scissors, rolling pin, hammer, drill, wrench, saw, welding torch, sewing needle, instrument, guitar pick, pickaxe, shovel, dumbbell, jump rope, paddle, piton, hiking pole.
