My Nest Protect smoke detector died. And now I am learning that it is normal for a smoke detector to flash bright green every 60 seconds? Who on earth thought a flashing light in a product mandated in bedrooms was a good idea???

SF is saying a *Walgreens building* must be preserved because something quite notable happened inside the building many decades ago. Put up a plaque! Preserving our built environment is a silly way to honor the past.
Q5 is how the Walgreens on the corner is a contributor to the culutral district when it has a minimal association with LGBTQ+ history. How is the department assessing the level of significance? Westhoff says that he'd have to check, but thinks that's where the first cases of AIDS were documented.

Hot take: dog piling on social media educates casual onlookers about a topic.
good god, this is how his Kate Willett arc begins, isn't it
When your product absolutely, positively does not increase congestion.
Items prices by markets do not suffer from an induced supply problem. Prices counter demand. That’s the point.
induced demand for the major cities and job hubs is just as real, you're just producing more supply to be immediately sopped up by new residents, not alleviating the existing affordability issue
Climate researcher opposes dense housing near transit. Berkeley is not okay.
Another reason is local advocacy against the density near transit necessary to sustain transit. Btw, density also enables higher levels of affordability.

Backing Prop G is madness. We have already voted on this TWICE. Chan is the new avatar of SF NIMBYs, always opposed to parks and transit and housing.
Sunset Dunes has become a proxy battle in SF’s congressional race. Scott Wiener wrote the official argument against Prop. G. Connie Chan backs it, quietly. missionlocal.org/2026/09/suns...
when METR used GPT Sol to analyze the transcripts of the attack, it would claim that the attack was fine because *the agent message board* had approved it.
Major news: SF's most infamous empty car wash will finally start to become housing this year. The empty car wash on 400 Divis has become a symbol of SF's stalled housing pipeline. It's no accident that this project will be one of the first housing projects to break ground this year.
We keep paying more for SFPD and we keep getting less out of them
This is an absolutely enraging story about how vile SFPD’s record of investigating rape is. Worst in country for cities its size. But that’s only the beginning sfstandard.com/2026/07/20/s...
Why do we subsidize new car ownership more than used car ownership? Doesn’t Sacramento know that used cars are more environmentally friendly than new cars?
California provides $3,500 to new EV purchasers and $1,750 towards the purchase of a used EV. How much does your state offer to help clear up the air there?
Chat: Are you voting yes or no on Prop 45, which overhauls CEQA? Does the fact that it explicitly carves out California High Speed Rail so that CEQA continues to slow down CAHSR, change your opinion? oag.ca.gov/system/files...
Really interesting polling result on Prop 45, the CEQA reform measure that will be on the November ballot. It polls best among Democrats and lower among supposedly deregulatory Republicans. Additionally, it was strongest among renters, young people, and low-income earners.
Yesterday, WIRED learned that Madison Square Garden was suing us for our accurate reporting. We stand by our work. That’s why we’re removing the paywall from two of the MSG stories they don’t want you to read, making them free for everyone.
We need our member of Congress to go to the mat for transit, not obstruct it.
The takeaway for cities: “The best bang for your buck is protected bike lanes,” Moran told Bike Talk‘s Nick Richert. “Really focus on bike infrastructure that’s protected. That’s how you grow ridership. That’s how you diversify ridership.” sf.streetsblog.org/2026/07/08/s...

Did you know SF's conflicting housing laws can make us choose between a bathroom and housing? Our Building code requires a restroom on a rooftop common space. But our Planning code inadvertently requires that restroom count against the building's height limit. Make it make sense!
As I've said many times before, we need to be much more aggressive about taking away people's licenses. No one was harmed this time, but what about next time?
Paul Pelosi is 86 years old and has the money to afford a driver. There is no reason why he should still be behind the wheel. www.politico.com/news/2026/07...
For context, the 9 counties of the San Francisco Bay Area has a population of 7.8M (compared to NYC's 8.5M), covers 6,966 square miles (compared to NYC's 472) and permitted just 16,008 new housing units last year.
".. The city added 38,682 units to its housing stock last year—the most new apartments completed in a single year for the city since 1965 .." @wsj.com #NYC www.wsj.com/real-estate/...
This is the most purely anti-American thing I've ever heard a politician say, but the media is too obsessed with 3 DSA candidates winning local elections in NY to pay any attention I guess.
What on earth are these… pellets? They look like a pile of shit

Did DoD just admit in a court filing that it used xAI's Grok Gov Model to hit the girls' school on the first day of the Iran war? Based on some passages flagged by @rgoodlaw.bsky.social in DoD's recent filing in NAACP's case against X, it looks like it did 1/

I’m a proponent of the Housing Theory of Everything but even for me this is a bridge too far
I’m at the housing regulator. I’m at the intelligence agency. I’m at the combination housing and intelligence agency.
How did Noe Valley get gentrified? We just may never know
Pretty disappointing to see SFPD parked in the bike lane directly in front of their station, just 50 feet from their designated parking lot.
