New paper out in @EnvSciTech today! How do you measure urban air pollution at high resolution in space and time? PhD student @Chirag_M95 came up with a new method that combines mobile monitoring with low-cost sensor data. Read🧵 for paper & details

SFMTA Board just killed Slow Chenery for no good reason. Sets an absolutely terrible precedent that a couple loud angry voices can make our roads more dangerous and hostile to those outside of cars

Bernal Cut, 1923 South from the Richland Avenue Bridge. Now, San Jose Ave & the J-line streetcar roar through the former Southern Pacific right-of-way. From the fantastic collection of the Western Railway Museum. @BAERA_WRM p.s. there's a kid taking a shortcut. #sfhistory

Sorry to interrupt the fun, but I'm deeply saddened to hear that Fred Brooks has passed away. He was a great man whose impact on our industry is incalculable. I'm forever indebted to him for his support in the fight for the right to reimplement APIs. @SteveBellovin/109362211705242308" target="_blank" rel="nofollow noopener">mastodon.lawprofs.org/@SteveBellovin…

I'm in the Valley for two days meeting with customers and working with AWS teams. Staying in Santa Clara and I have a car. Can anyone recommend a nice 5k-ish walk in the area?

So I'd like to visualize a bunch of events with duration on a timeline. I would prefer not to write exploratory D3 code for this. What do people use?

Great sleuthing by my co-worker Shrey medium.com/airtable-eng/t…! Vegalite, one of my favorite visualization systems, makes a guest appearance too.

SELECT col2, sum(col3) GROUP BY col2 ORDER BY 3 ≈ awk '{ x[$2] += $3 } END { for (i in x) { print i, x[i] } }' | sort -n -k 2

Inspired by @hytradboi, a use case for Datasette/sqlite: a CI job called "Querybook" (after Storybook) that logs queries and stack traces of all SQL the app does and publishes them in a sqlite db. Open Datasette to answer the age-old question: "what function causes that query?"
