Thin boi!

New trees and landscaping outside Paris City Hall (Hôtel d'Ville)

Saint Paul

Lovely pedestrianized street by a public library (historique de la Ville de Paris), Le Marais

Good morning, 11 arr.

Rue Beaurepaire

Lovely light on République

Rue de Nice, 2023-2026

Ligne 14, baby!

SF really is the GOAT.

Texas A&M spends about 1.5 billion on research in a year, about as much as the nation of Czechia.

Similarly to New York's, SF's chinatown has: - high transit ridership - low car ownership - overly narrow sidewalks

Been using Lime a bit (in addition to my mainstay, BayWheels), and it's such a reminder how right sized scooters are to urban travel

I love SF

Lovely exhibit on Modernism and California at the College of Environmental Design Library at UC Berkeley.

🧵 Public science in the US has taken some heavy hits over the last year, but the White House OMB is proposing a series of changes that will result in a TKO for science as we know it unless we fight back. Here's what's happening, and why it matters. 1/n

Good on the Times for hounding the admin about this. www.nytimes.com/2026/05/29/u...

Uncommon version of intersection day-lighting, Presidio Heights. Ain't bad - and would be even better with a bike-rack in between the slabs.

It’s a real renters market in Sacramento rn I’m seeing buildings that were developed 5 years ago offering rents below what they were offering when they first opened. Building housing works.

TIL that the basic research that led to GLP-1 drugs was conducted by government scientists at the VA and NIH whyy.org/segments/oze...

The Indiana state legislature has thrown sand in the gears of many transit/street projects in Indianapolis

Today on Volts: Minnesota utility Xcel is installing small-scale batteries on commercial & industrial land. It may not sound like much, but @pierlafarge.bsky.social says it augurs a new chapter for the US grid, wherein storage will enable big new loads like data centers to reduce rates for everyone.

Electric semis, baby! www.nytimes.com/2026/05/19/b...

Carvana's furious growth isn't hard to figure out: no-haggle pricing for used cars, online shopping, delivery to your driveway. Now it's applying the same playbook to new cars. The project is small for now, but it has traditional dealers freaking out. (Gift link) www.wsj.com/business/aut...

I try no to think too hard about how many drivers seem to be mostly unaware of what they’re doing or what’s going on around them

"Previous research has also shown that increased immigration enforcement slows housing construction, drives up home prices and leads to job losses for American-born workers." www.nytimes.com/2026/05/19/r...

Switzerland’s incomparable Lauterbrunnen Valley. (Said to be the inspiration for Tolkien’s Rivendell.) To make it a truly Swiss experience, the photo was taken from a moving train. 📷

Powerful reporting and imagery from the Times on the expansion of the warehouse/logistics industry in America: www.nytimes.com/interactive/...

Nice piece on housing supply and prices from the Times: www.nytimes.com/interactive/...

US House GOP & Dems have compromised on 5-year transportation bill. Draft bill includes a $150 annual fee on electric vehicles ($35 for plugins). No fee on gas-powered cars. Though not huge, this is another disincentive to shift to EVs in a country where the EV market share is low & declining.

Three people were killed and several others were injured after a vehicle struck cars and pedestrians near International Boulevard in Oakland late Saturday.

Bike parking in Cole Valley

First time seeing a Wayve test car on the streets of SF

5K CLUB LES GOOOOOOOOO

A state that redraws its legislative maps before every election to maximize advantage for the incumbent party is not a democracy or a republic and in any case obviously violates the guarantee clause, among many others. No country does this. No country ever thought of doing this. It is a total farce.

"The unexpected boom in home batteries and the equally surprising surge in rooftop solar installations means that Australia’s target of 82 per cent renewables by 2030 – long dismissed as a lost cause by some – is now very much within reach."

University of Illinois spends ~10x the research budget of Polytechnique

Nice intersection day-lighting in Noe Valley

The interview is bonkers, and what I truly believe (and tell my students) is that it will always be important to know things. You can't evaluate AI-generated material if you have no knowledge of a field.

This graph shows two things, 1) obviously that the cameras reduced speeding, but 2) that the improvement kept getting better over time. Speeders tend to get one or two tickets and then learn and change their behaviour. This isn't a cash grab, it's an extremely useful intervention.

Murder rate in NYC, Philly, Baltimore, and DC January to April 2026 has never been lower on record (using data from the essential @jeffasher.bsky.social).

On this morning's express Caltrain from SF to SJ both bike cars were at capacity such that the conductor had to make an announcement. Riders are back.
