I’ve been working on a new chapter for my upcoming DuckDB book (duckdb.gishub.org), focusing on large-scale geospatial analytics. As part of the chapter, I generated an H3 heatmap of 2.5 billion global building footprints from Overture Maps.

Stay tuned for the book release!

Tariffs are bad, but I'd have more sympathy for US transit agencies if they weren't inflating the costs of new buses by customizing absolutely everything (and fighting against efforts to lower costs by standardizing designs).
North American bus manufacturers, transit associations brace for new 10% bus tariff
Without relief mechanisms, transit agencies could lose buying power and have to delay climate-driven purchases.

Impossible! Ann Arbor is a special place. No lessons from other cities apply here. We have to invent everything from scratch with a process that takes a minimum of 20 years and involves at least a dozen postcards sent registered mail to each homeowner (but no renters, please) #a2council
Similar stuff happening in Cambridge 🙄

@aadl.org is the leaner New shelf downtown because people cleaned out the books (yay!), or has the Baker and Taylor closure hit home?

📣THREAD: It’s surprising to me that so many people were surprised to learn that Signal runs partly on AWS (something we can do because we use encryption to make sure no one but you–not AWS, not Signal, not anyone–can access your comms).

It’s also concerning. 1/
PSA: we're aware that Signal is down for some people. This appears to be related to a major AWS outage. Stand by.

Can we turn the Ypsilanti data center into a municipal steam system?

I wish @aadl.org had delivery. Mostly because I’m too lazy to pick up my holds today. I’d pick up some volunteer shifts to cargo bike books to folks …

Something of a garden cleanout bouquet this week. Sage, broccoli and basil flowers, with the usual ammis and zinnias.

This is not true. Blackstone owns 0.06% of the single family homes in America. There is no market where they own more than 1% of the homes.

Nobody has a monopoly on housing. 2/3 of American households own their homes and rental housing is a VERY diversified and competitive industry.

my father-in-law is a “I know a guy” Guy. sadly all the old Guys are aging out of the Guy Economy. Guys are fundamentally incompatible with Hustle Culture because it’s not about “winning” a deal, it’s about collecting favors and goodwill in a mutually-beneficial cycle. protect your local Guy Economy
