One more thing. When I wrote about this study showing one-third of Americans don't drive, people were messaging me saying this cannot be true for LA.
In LA County *23 percent* of the population is under 16. Kids are people! We must plan for their movement, just like all nondrivers. Hope that helps!

Highly recommend diving into NRDC's study on car access, which @keawilson.bsky.social wrote about here: usa.streetsblog.org/2025/10/02/report-16-million-have-no-car-access-at-all
Where Nadir was killed, 14% of LA households are car-free. But the infrastructure does not match that reality

i'll go so far as to say that the PDS as a user-controlled auth/storage layer that clients can connect to directly is the single most important part of atproto. requiring application servers would dramatically increase the cost and difficulty of building atproto apps.
Nerding out about the question of whether the client or the server should be the one who speaks to the PDS
The politics of purely client-side apps
There's a surprisingly nuanced discussion in development about the political economy of clients and servers in the Atmosphere

interesting article. the flip side is that if LLMs have a 12–18 month lag in their training data, you can get a free year-or-so head start over your peers who rely on them

any a11y folks know how to improve this? is it better to add roles and aria attributes as best i can, or should i wait for actual support for aria across shadow roots?
threw together a lil web component to add this to any input. super easy progressive UX enhancement for your atproto app!

Yesterday at TPAC I publicized my draft proposal for adding a declarative templating API to the DOM.
github.com/justinfagnan...
The repo has:
📖 Explainers for the templating API and DOM scheduler API
🏗️ Full prototype implementations
⚗️ a JSX transform
⚛️ a mini React-like framework

Unable to attend this week's awesome-looking @syncconf.bsky.social, I've decided instead to offer a tribute in the only form I know how: a new open source project. 👐
I believe sync is a fundamental part of modern app development. Hopefully I can help make it easier.
Please follow along!

Most people see the web as a glorified document viewer, I look it as a malleable computing substrate that has yet to be fully actualized.

So it turns out... the US air travel system was incredibly, deeply dependent on federal funding to just run day-to-day all this time, to the benefit of private airline shareholders, when everyone thinks that state-run trains are leeching off the government. Weird!

the "no nazi tattoos is a purity test!!" graham platner defenders are obviously whining in bad faith, and you can tell because there are other candidates in the race they've already chosen not to support.
oh, so janet mills is too moderate?
