If I didn’t already like my header photo I think I’d use this lede from my hometown newspaper in an article about my high school quiz bowl team circa 2010 instead

Some parts of the state are waking up to snow on the ground on this cold November 9.
While not a big snowmaker, it’s the first measurable snowfall across southern Wisconsin, and wind chills have dipped into the single digits and teens across the state.
Stay warm this weekend!

✅ pad thai (also make with sweet corn, new as of today)

If your random seed is 42 I will come to your office and set your computer on fire🔥
Figuratively. More likely you'll get a stern talking to.

This is a backdoor path from the Son to the Holy Spirit that should be closed by conditioning or stratifying on the Father.
I have found an EXCELLENT meme for the church history lecture on Wednesday (which includes the Great Schism)

1) found an implementation of something I needed on CRAN
2) it didn’t have a feature I needed
3) wrote the feature, tested it
4) found a GitHub repo from the maintainer under the package name
5) forked it, started on a PR
6) only then realized the repo isn’t actually for the CRAN package (???)

R-Universe by @rOpenSci is an extremely useful project.
My latest R package, {pmtiles}, is not a good fit for CRAN as it bundles a pre-compiled Go library.
With R-Universe, I was able to get installable cross-platform binaries built in hours!

"Many people still have an elderly relative who survived a bout of severe childhood illness; not one of us has an elderly relative who did not."
This is the best and perhaps most important illustration of sample selection i have seen in a good long while.

Good history helps us avoid nostalgia. The great article “Economic History and the Historians” (2020) by Anne McCants reminds me why nostalgia can get us in trouble. Two of her examples are very relevant to today: vaccinations and the popular narrative of some economic “good old days.”
