Obama on the Iran nuclear deal today:
“We pulled it off without firing a missile. We got 97% of their enriched uranium out. There’s no dispute that it worked. We didn’t have to kill a whole bunch of people or shut down the Strait of Hormuz.”
$25 billion spent. 14 Americans dead.
Oil at $119 a barrel. The world has one month of strategic reserves left. A UAE oil port on fire. Ships turning back at gunpoint.
Trump called Obama’s deal the worst deal ever made.
Then tore it up.
Then started a war to get back to the same place.

An underrated use case with Claude Code or Codex is simply combining and editing PDFs.
Trying to do it in Preview or Adobe Acrobat is a nightmare. Instead I can just tell the AI to do it.
It's also amazing at cropping scanned PDFs, just tell it to "Crop out the empty spaces."

How we built the Codex sandbox for Windows:
OpenAI Developers: To bring Codex to Windows, we had to answer a hard question: how do you let coding agents stay useful without forcing developers to choose between constant approval prompts and full machine access?

Re // Idea validation
I ran the idea through @garrytan gstack's office hours.
The feedback that stuck:
"Building infrastructure before demand, a calculated bet, not an oversight. Agentic commerce is inevitable, and being first with a working proof of concept matters more than waiting for demand to emerge naturally."
That landed.🫡
Alot of discourse about this announcement today.
I think one thing I learned about engaging your customers is you just have to be honest and upfront about your constraints.
Especially with developers - they really just want communication that tells it like it is. It's very hard to earn their trust and once lost it's very hard to earn it back.
Honestly, everyone who needs to communicate with developers should read this article from @leerob: https://leerob.com/developer-marketing

Legacy media besmirches itself when it quotes people who personally benefit from more fentanyl tourism
Defund nonprofits that support people doing drugs until they die. Fund recovery and treatment in SF and everywhere in on the West Coast
MissionLoco: There’s a big plus in the gaslighting charade called “news” coverage of the fentanyl tourism crisis (which the “news” still calls “homelessness” 10 yrs in) — they still drag out this creature to do the gaslighting. It’s like using Josef Mengele as spokesman for Kaiser Permanente.
New “datacenters consume all the world’s water” just dropped
Kelsey Piper: Are autonomous vehicles (self-driving cars) “less able to detect people of color”? That’s what I read in The Atlantic this weekend, in Xochitl Gonzalez’s “People Who Don’t Like People Are Making All of Our Decisions.”
It appears to be entirely false.

Adialante is one of the most ambitious companies in the batch. They are building a 10x better MRI that will save many lives in the future!
Y Combinator: Cancer kills because it's caught late. Adialante is changing that by making mobile MRI accessible — dropping its costs to hundreds per scan and wait times to hours. Annual cancer screening will be the norm.
Congrats on the launch, @ET_adialante &

KQED published a "voter guide" on Prop D that is six sentences long
It never mentions that the "CEO tax" is actually a gross receipts tax on sales, not on executives
It never mentions Google (32:1 ratio) is EXEMPT while Walgreens (410:1) gets an 800% tax increase
It never mentions grocery stores run on 1-3% margins and can't absorb this
It never mentions the Dodd-Frank formula is trivially gameable
It never mentions the Board of Supervisors can't adjust the rates without going back to voters
If you're going to call something an explainer, explain something. Otherwise you're just laundering anti-tech anti-prosperity talking points as journalism.
KQED fails to do even basic journalism and fails the people of the San Francisco Bay Area

beautiful tech stack writeup, one of the best i've ever seen in my career.
I always advocate that devtools companies write these up, because it fulfils multiple purposes:
- tell users the care that goes into the product
- tell hires that there's SOTA work here
- tell competitors to give up
- gives back to community
- (nuanced) tell non-fits why they can't have what they want when they think it's an easy request
few actually do this mostly because they don't actually have sufficient depth, or aren't sufficiently good at notetaking/systematic about problemsolving ('its just vibes' or 'honestly we just went with the first thing that worked' doesn't come across as well, so rather not say anything)
so when you've done the work, show the work.

APPLEBAUM: Russia's war in Ukraine is sometimes described, including recently by American Vice President, as if it were nothing more than territorial dispute, kind of scuffle over lines on map.
But when Russia denies that Ukraine is a real nation, builds concentration camps on Ukrainian territory, bans Ukrainian language and systematically arrests mayors, teachers, journalists, and priests, then Russia is also attacking Europe that was built after 1945, Europe whose borders are not supposed to be changed by force.
Russia invaded Ukraine not only to destroy Ukraine but also to prove that treaties are meaningless, alliances are weak, and brute force still decides fate of nations.
By waging imperial war of conquest, Russia seeks to undermine Europe's post-imperial order.

Data centers are generating trillions of dollars in value for the economy.
Data centers don’t consume water, they return it to the environment.
Data centers lower household energy costs by producing their own electricity and generating stable demand that reduces operating costs for the grid.
Data centers create jobs for construction workers, electricians, and other skilled workers year round, all across the country.
Data centers data centers pay billions in state and local taxes without using public services, meaning more resources for the rest of us.
Data centers power every part of the digital economy in ways most people don’t even know, even enabling things as mundane as stocking products at grocery stores.
Data centers are driving the AI revolution that will keep America ahead of China and enable universal high income for everyone.

Everyone switching from Markdown to HTML is missing the nuance.
The optimal approach (most of the time):
If it's for a human to read, yeah, use HTML.

If an agent is consuming it, use Markdown!

3. DOJ helps Trump get $10 billion from the IRS because they caught him cheating on his taxes.
4. Americans who don't cheat on taxes will foot the bill.

"My fear is that society, built as it is, locks people away into default paths...
like just become a management consultant, go get your MBA, this is safe, you'll get your pension, you'll have your nice vacations, drive your BMW, and like there's nothing wrong with that, and that's a great life, and I want more people to have that.
On the other hand...
Rick Rubin: There's so much more.
God gave you this brain, and God gave you these senses, and we can do so much, and how do we do more?

Abridge: 100M+ medical conversations, real-time prior auth, and the clinical intelligence layer https://www.latent.space/p/abridge
@AbridgeHQ is building the clinical intelligence layer for healthcare. In this episode, Janie Lee and @c_asawa explain why ambient documentation was only the first wedge, how Abridge is turning patient conversations into real-time clinical decision support, why healthcare may become one of AI’s most important proving grounds, and how 100M+ medical conversations, specialty-specific evals, and deep EHR integrations create a moat for AI-native healthcare.
