Waymo Is Not In The 'Vision Zero' Toolbox: Data - Streetsblog New York City At least two of the cities where Waymo operates have not experienced declines in traffic-related injuries and deaths.

"Waymo has told advocates that expecting it to respect bike lanes is 'too high a bar' because customers expect to be dropped off in them."

To be crystal clear, it's illegal for a car to be in a bike lane. It doesn't matter what Waymo's customers expect; the company shouldn't be doing it.

Flipboard’s Surf app is a big new idea about the future of social This might be the first great fediverse app.

There's an app called Surf that lets you choose to entirely ignore politics, maybe take a nice respite.

The Flipboard team built it as a way to browse the decentralized world.

It's still in beta, but you might want to get on the waitlist. I really like the trending searches feed.

Harvard has set an example for other higher-ed institutions - rejecting an unlawful and ham-handed attempt to stifle academic freedom, while taking steps to make sure students can benefit from an environment of intellectual inquiry, rigorous debate and mutual respect. Let’s hope others follow suit.

Imagine "putting a lot of thought" into how you show off your tech, and the best you can do is "look at this artist who hates us whose work we're going to blatantly steal" instead of all the countless positive ways your technology could be used.

OpenAI is the worst version of what it could be.

2. The way #atproto lowers barriers to developers of middle-tier solutions via lexicons/appviews is so powerful/unique. Account/data portability is just part of the magic!

I'm proud and excited to be part of a team working hard to bring #atproto benefits to a wider audience via @surf.social

#ATmosphereConf was the most informative and inspiring conference I've ever attended.

A couple of initial takeaways:

1. (obvious, but super-reinforced) The community is driven by deeply positive goals and empowered with hard-won lessons that apply to every community type and size imaginable.

Optimism of the early web and the pessimism of the consolidating web. “Society has come to reflect the dominant form of technology”. You might have a chance to alter the course of history if you work hard enough. @jay.bsky.team’s talk at #atmosphereconf @bsky.app
