It is harder to do labour economics in an underdeveloped country. Without specialized human capital, people move from one sector to another, one place to another, to make ends meet. Home and work are often intermixed. I long for Norway.

I know some things because I've had weird obsessions since middle school. That's also why I don't know many things.

often, i find myself in positions of having to explain how it is i know things that I Just Know. the real answer is "I am insane" and people don't often like this answer. but...you have to be a little batshit to navigate around human limits. otherwise, you don't know what they are.

Was trying to explain to a traditional IT person yesterday why #duckdb is so great and didn't succeed. The ergonomic fit it has to a single person on their own laptop running ad hoc queries interactively on data that is somewhat big but not too big is hard for outsiders to appreciate.

Next week I'm teaching poverty measurement and I made a little shiny app where students can move incomes or the poverty line around and see how various common poverty measures change. Feel free to use or share or tell me what I should add or modify. ryanbriggs.shinyapps.io/Poverty_Meas...

Trying to isolate out some of the things I like about R, thanks to a tip from @shriram.bsky.social I discovered Shutt's thesis on the vau-calculus, which lets you define function-likes which get their arguments unevaluated. dcreager.net/pdf/Shutt201...

Screengrab from the Netflix movie 'Jaane Jaan'. Anyone have an idea what math this is? Reddit says it is a spectral sequence calculation.

My favourite textbook of all time: Introduction to Electrodynamics by Griffiths. What is yours?

Also work in progress, but over a longer horizon. Pure math. Most interested and best prepared right now in probability theory but also curious about logic and set theory.

My to-do list. High-dimensional probability and statistics. Vershynin, Wainwright and others.
