San Francisco has all the ingredients. - Talent. - Capital. - Culture of creation and risk taking. - Tons to do. - Supportive echosystem of innovation. - Diversity. - Natural beauty. All we are missing is a coherent local government. Once we get our shit together, we will witness another long boom. It's on us, the voters. I'm optimistic. I believe in San Francisco!

Codex is not like claude code. if you know the limit is going to end, like last 10 to 8%, give an very long run task, and even after the limit got ever, it will continue to do the task until the task was completed. Shout out to @OpenAI team.

It's literally all Claude eating their lunch. Lagging indicator. Cracked devs on X are leading indicators. Everyone I know switched to Codex. Give it a month and it will be apparent in revenue numbers.
"OpenAI Chief Financial Officer Sarah Friar has told other company leaders that she is worried the company might not be able to pay for future computing contracts if revenue doesn’t grow fast enough" this could be a problem for the AI bubble

Normal Californians: This is the guy
San José Mayor Matt Mahan has seen his odds to become the next California Governor more than double in the last 48 hours from 6% to 14%. He’s in second place behind Tom Steyer (53%)

This lady intentionally commits a serious crime, she and her office try to cover it up, she then avoids investigators by claiming a “mental health crisis” and stops going to work (for months), all at the expense of SF residents & businesses. She is the poster child of socialism.

Jackie Fielder is clearly unfit for office and must resign. She literally can’t be relied upon to fulfill her duties. She should resign partly because she’s in mental health crisis and absent but MOSTLY because she allegedly broke the law by leaking confidential city documents for political reasons. Are we not going to have simple standards? Call me old fashioned but I prefer my elected officials to be of sound mind, to show up for work, and to NOT BREAK THE LAW. She has to go and I hope she’s prosecuted to the full extent of the law for the illegal leaks. I also hope she gets help, recovers, finds happiness, and a gets less stressful job that suits her.
Before San Francisco Supervisor Jackie Fielder stopped attending meetings and said from a hospital last week that she was considering resigning, her office had become the focus of a city investigation into the leak of a confidential memo, according to a person familiar with the matter. sfchronicle.com/sf/article/s…

San Francisco is on the ups but only because a small number of moderates were elected. The majority is fragile so these races are critical to keep the momentum. Follow @GrowSF and support @mattdorsey, Manny Yekutiel, and @theoellingtonSF for supervisor in the November election.
Apr 8
We are proud to endorse @MattDorsey (District 6), Manny Yekutiel (District 8), and @TheoEllington (District 10) for Supervisor in the November election. These are leaders who understand that we need more housing, safer streets, and a city government that delivers results.

Shutting down abundant, clean, and reliable energy is moronic. This facility should be expanded. Nuclear is safe, clean, and very environmentally friendly.
OPINION: California’s last remaining nuclear facility, scheduled to be shuttered in four years, provides 17% of California’s clean, carbon-free electricity. sfchronicle.com/opinion/open…

After Richmond disabled its Flock cameras to "protect immigrants," car thefts jumped 33%. Immigrant shopkeepers begged to bring them back. Last week their city council finally listened. Opposing safety cameras is a luxury belief. gli.st/nfolm33i

California has increased spending by 75% in six years. Are your bills 75% cheaper? Are our schools 75% better? No. Because the problem isn’t how much we spend — it’s how we spend it. And I’ll only spend taxpayer dollars on policies that actually make people’s lives better. Plan out tomorrow. Thanks for the conversation @friedberg!

Oregon may ban unfunded affordable housing mandates — because data proves they suppress homebuilding. When cities require below-market units without offsetting costs, developers build fewer homes, pushing up prices for everyone. California still uses the same counterproductive approach that Oregon may ban. sightline.org/2026/03/05/ore…

This is almost as bad as the law requiring office phone booths to be sprinklered. Installing sprinklers in these booths costs more than the booths themselves…. I have a solution! 💡 If there is a fire, maybe exit the phone booths 🤷‍♂️ I’m sure the sprinkler companies and the union labor that handles installation had nothing to do with these laws There are hundreds of examples of regulatory capture in construction just like this.
Wow am very surprised to hear this Next you’ll tell me the pipefitters union was involved somehow in pushing for this ordinance that involves fitting lots of pipes

The tech Barrons of today need to learn a lesson from business titans of America’s past. Look at Carnegie: 🏗️ Andrew Carnegie (Carnegie Steel) Context: Carnegie famously wrote The Gospel of Wealth, arguing that the rich have a moral duty to redistribute their fortunes. Key philanthropic actions •Funded construction of ~2,500 public libraries worldwide through the Carnegie Corporation of New York. •Established the Carnegie Mellon University and the Carnegie Institution for Science to advance science and engineering. •Created the Carnegie Endowment for International Peace to promote diplomacy and peace. •Donated roughly 90% of his fortune (~$350M at the time) to education, culture, and research. Build cool stuff for your communities that improve daily life. Parks, beautiful mixed use buildings, amazing art installations and monuments.
AI is deeply unpopular. According to Pew, sadly only 17% of Americans think AI will have a positive impact. In China, 83% believe AI will be positive. A token tax & political backlash is coming unless the narrative changes. 🇺🇸👀🧐

It's actually never been cheaper to rent in Austin, TX. The Rent/Income ratio across the metro has dropped to 18.3% - the lowest on record (going back at least 20 years). Landlords are aggressively cutting rents at a time when incomes in Austin keep rising. The typical rent is down to $1,565/month. While the median income is up to $100k. Making Austin the cheapest city to rent relative to income.

Just out: California's wealth tax proposal has a NEGATIVE $25B net present value. We project only ~$40B collected (vs. $100B claimed), with ~30% of the tax base already gone and lost income taxes wiping out gains. w/ Ben Jaros, @gregkkearney, John Doran & Matheus Cosso: papers.ssrn.com/sol3/papers.…

If your child becomes a reader, about 80% of the education job is already done. That's my honest assessment after working in education for over thirty years. Everything else is secondary. Most parents think science education is important. Yes it is. But if you can't read the biology textbook, you're not going to learn biology. Reading is the meta-skill that enables all other skills. History requires reading. Science requires reading. Even math increasingly requires reading as it becomes more sophisticated. The child who reads voraciously will figure out everything else. The child who doesn't will struggle with everything.
