Agree. Which is why I wear a mask on buses

Chat should we build housing where the daytime high is 72 or 94?

This would more or less halt the ability of scientists and academics from visiting the US to give talks, attend meetings and workshops, collaborate with peers on research and I think that is the primary point. ๐Ÿงช

Hi, former Foreign Service Officer here

The Secretary of State might be interested to learn that visa requirements and terms are generally reciprocal. We do it to them, they do it to us.

Took the K train and LAX Metro shuttle bus to pick up visitors at the International Terminal today. I was one of 2 people on the bus wearing a mask. Not good when there is so little fresh air on a crowded bus.

One of the worst things about driving is other drivers. One of the best things about cycling is other cyclists.

Maritza Rivera proposed an amendment to the comprehensive plan that would allow the city to require builders to go back and create new site plans if ANY tree, including the tiniest sapling, would have to be removed because of the proposed site plan.

I worked in DMSP and NPOESS. It's hard and honorable work. Even if we don't measure CO2, other nations are doing it, too.
We are beyond 1984 levels of authoritarianism

2019โ€ฏโ€“โ€ฏ2024 โ€“ Repeated denials and discovery stonewalling
Through years of communications with the police, the plaintiffs and the court through the investigation and later the discovery process for the lawsuit, Tesla never mentioned that it had all the data that explained how Autopilot saw the crash, which everyone was seeking, sitting on its servers for years.

The facts are:

Tesla had the data on its servers within minutes of the crash
When the police sought the data, Tesla redirected them toward other data
When the police sought Teslaโ€™s help in extracting it from the computer, Tesla falsely claimed it was โ€œcorruptedโ€
Tesla invented an โ€œauto-deleteโ€ feature that didnโ€™t exist to try explain why it couldnโ€™t originally find the data in the computer
When the plaintiffs asked for the data, Tesla said that it didnโ€™t exist
Tesla only admitted to the existence of the data once presented with forensic evidence that it was created and transfered to its servers.

This whole story is insane. Tesla apparently did everything it could to avoid providing the data it had about its Autopilot crash. This is just a snippet and there's a lot more. electrek.co/2025/08/04/t...

No one should ever have to wonder if their senator or representative is making choices in Congress just to benefit their own wallet.

There's a clear solution: ban Congressional stock trading.

If you, regular person, did anything like this after a fatal car accident, you would be prosecuted for a variety of crimes, including insurance fraud.

If you then repeatedly lied to the courts about it, like Tesla did, you'd get prosecuted for that too, plus stiff monetary sanctions.

I installed a front crate with @americanfietser.bsky.social's encouragement. The handling difference between pushing and pulling weight is noticeable. I like the ability to balance the two

It's literally every few days a high quality new paper comes out telling you, yet again, you do not want this shit (= covid), and this one's telling us we probs should've been more cautious all along about common colds too--like not going into the fucking office when you have one!

say it again:

4 million people work in higher ed, the largest employer in 10 states, second largest employer in 10 more, and in 60 of the 100 biggest cities

demolishing higher education is economic sabotage

LAUSD teachers earn too much to live in the affordable housing apartments built for them In the mid-2000s, in the midst of a housing boom, the Los Angeles Unified School District realized that skyrocketing rents were fueling teacher turnover.

I don't know. I called them Sunset Stuccos when I visited family friends there. Asian people couldn't buy in most parts of SF (covenants, realtors), so many ended up in these moldy piles in the Sunset District

the USA built a system of higher education so good that smart/rich people from across the world came here, spending billions to learn here, subsidizing education for Americans while spending money to live in our cities and towns. our government arbitrarily decided we should stop doing that
