Interesting. What exactly does that mean? Harmony or Jive?

american-style intersections function with an order-of-magnitude higher safety and throughput and a much smaller square meter 'footprint' if they switch from 'controlled' intersections (lights, stop signs) to 'traffic beans': [0]

[0]: https://zoningverydifferentthanours.substack.com/p/a-pattern...

This gets complicated because the reason things are the way they are is _crucial_ to efficient, easy change, and the greater united states is a place obsessed with continuing _ethnic cleansing_. it's sad and tiring to exist inside of, the dehumanization caused every day, anew, by american style road networks, supremacy.

tl;dr american road networks and american zoning is two sides of the coin some groups used to accomplish 'regimes of social control', which was a mix of ethnic cleansing for some neighborhoods, and ensuring conformity for others.

Oh, and a cool data visualization project. Here's a map of most of my travel for the last few years: https://josh.works/mobility-data

Not exactly Nobel worthy. :-)

I’m rebuilding a learning library. Webpage bookmarks (with big help from raindrop.io), PDFs (hundreds of them, mostly book chapters), images, jupyter notebooks, markdowns, etc. using a Jekyll static site generator to minimize the tech stack hairballs.

The interesting part is that nearly all of the content is tagged to associate with two or more domains ex:

Goodreads-history-truecrime

PyTorch-Jupyter

Rubyonrails-Testing

Behavior-Gaslighting

Semiconductors-GPUs

And so on.

It’s an exercise in taxonomy creation. Searching by tag doesn’t quite get it. And we all know PDF auto summaries are tough.

I’m not expecting anybody to be impressed. It keeps me occupied while learning how to be (unfortunately) retired.
