there's a ~complete rough draft of Urban Analysis up on my website (as in, code executes all the way through) knaaptime.com/urban_analysis still lots of editing to do, but if you're into cities, Python, or spatial analysis, give it a look and let me know what's wrong :)

Finally updated the search engine behind econlit-db to Meilisearch. Everything should be quite fast now -- under a second or two. Let me know if you have any bugs. paulgp.com/econlit-pipe...

on the one hand, it's dope to see spatial analysis win Econometrica's best paper (!) on the other, it's so deeply troubling that this statement is news to economists in 2026

Wrote about how Hegseth’s effort to resegregate the upper ranks of the US military ties into the larger MAGA project to restore hierarchies of race and gender: www.theatlantic.com/ideas/2026/0...

"To put it bluntly, an X post today receives less than 3% of the views a single tweet delivered seven years ago." If you think it is necessary to be on Twitter to communicate your fact-based worldview, the reality is that worldview is being smothered.

BREAKING: In response to huge cuts in Trump's budget request, NSF is shuttering its SBE directorate. Staff will be transferred to other parts of the agency and "grants that align with Administration priorities" will be maintained. That & more w/ @maxkozlov.bsky.social & @edwrdchen.bsky.social

Kare 11 local news just read, in full, this statement from Michael and Susan Pretti, the parents of Alex Pretti. "Please get the truth out about our son."

Global datasets are really cool. Lots of fun to be had, I used this for looking at city evolution over time, sprawl, building heights, … Just really cool when one can do that globally with the click of a button. E.g.:

news from PySAL world: we have a new package in the ecosystem(!) As of today, `gwlearn` is available in package managers. It provides a suite of tools for geographically weighted machine learning using a sklearn API. pysal.org/gwlearn/v0.1... great work by lead author @martinfleischmann.net

another sweet port from Kyle! A touch of background on the original, for those interested: knaaptime.com/urban_analys...

My favorite #Python package to use is spopt, a library for spatial optimization. It helps you with: 📊 Facility location planning; 📊 Sales territory design; 📊 Maximizing market share; And much more! Check it out here: pysal.org/spopt/

Is logistic regression "AI"? What about convex optimization? Is LLM AI? What about an image recognition system built without using "feature learning" techniques but done through "feature engineering"?

classic.

furthermore, i dont care how this game turns out, or how many caleb williams apoligistst there are, malik is a better qb

tom. it's not called the windy city because of the weather.

seen this floating around all day, with exactly this thought every time. If you're prepared to spend a 7th of this much, you have not spent enough time in the midwest. the Home Alone house has been valued under 3M until 2024 and its *in the chicago metro* www.zillow.com/homedetails/...
