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???

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.

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.

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!

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.

Pretty disappointing to see SFPD parked in the bike lane directly in front of their station, just 50 feet from their designated parking lot.
