2mo's ago I asked Claude to perform a rough survival analysis to predict when musk would fall out of trump's favor. It put the median survival of trump's inner circle at 18.5 months, and estimated musk's relationship duration at that time as 16-17 months.

Absolutely nailed it Claude, great work.

Has anyone done a survival analysis on trump's good graces? I'm wondering what the ETA is on trump turning against elon.

I asked an LLM for a back-of-envelope estimate and it put mean survival for trump's inner circle at about 18 months.

China built hundreds of AI data centers to catch the AI boom. Now many stand unused.

China built hundreds of AI data centers to catch the AI boom. Now many stand unused.
The country poured billions into AI infrastructure, but the data center gold rush is unraveling as speculative investments collide with weak demand and DeepSeek shifts AI trends.

I'm amazed how many simple rule engines, if statements, and other basic logic flows are now being referred to as 'AI agents'.

Case in point, a tweet about an AI agent for email to reply automatically. We've had auto replies, rules and the like for decades.

A preview of an evaluation we have been working on: citation accuracy. When doing RAG are quotes from a source text correct or hallucinated?

i asked Claude to write a Barthelme-esque short story with the aesthetic sensibilities of "The School", and it gave me this. i mean. i mean.
For six months we watched the pigeons building their civilization on top of the skyscrapers. First came the architecture: nests made not just of twigs and paper, but of lost earbuds, expired credit cards, and the tiny silver bells from cat collars. Then came their laws. "They have a supreme court," said Dr. Fernandez, who'd been studying them since the beginning. "Nine pigeons who sit on the ledge of the Chrysler Building and coo about justice." We didn't believe her at first, but then we didn't believe a lot of things that turned out to be true. The pigeons developed a currency based on blue bottle caps. They established schools where young pigeons learned to dodge taxi cabs and identify the most generous hot dog vendors. Some of us tried to join their society, climbing to rooftops with offerings of breadcrumbs and philosophy textbooks, but the pigeons regarded us with the kind of pity usually reserved for very small children or very old cats. "They're planning something," the conspiracy theorists said, but they always say that. Still, we noticed the pigeons holding what looked like town halls, thousands of them gathered on the roof of the public library, bobbing their heads in what might have been voting or might have been prayer. Our own civilization continued below theirs. We went to work, fell in love, lost keys, found keys, forgot anniversaries, remembered too late, all while the pigeons above us built something that looked suspiciously like a scaled-down replica of the United Nations building out of discarded takeout containers and stolen Christmas lights. Sometimes they dropped things on us: rejection letters for poetry we'd never submitted, tax returns from years that hadn't happened yet, photographs of ourselves sleeping that we couldn't explain. Dr. Fernandez said this was their way of communicating. We said Dr. Fernandez had been spending too much time on rooftops. The pigeons started their own newspapers, printed on leaves that fell upward instead… For six months we watched the pigeons building their civilization on top of the skyscrapers.

Amazon advertising sales in 2023: $46.9 billion
Amazon net income 2023: $30.4 billion

Let's assume people start using AIs trained with Amazon reviews to shop on Amazon, without clicking on any ad.

So Amazon didn't have any other option that to stop giving the reviews to rival AIs.

Yup, there are almost fifteen million SQLite databases on Bluesky’s PDS servers. It’s wildly efficient and simple but not without trade offs of course.

Makes sense for this use case in large part because each users atproto repository is self contained, with links to other repos, like a website.

These two images explain perfectly the RTO of big companies, and the WFH of smaller ones. 15% of WFH engineers do nothing, vs 6% in the office, but 5x engineers are more common remotely. If you have a small motivated team, stay at home. You pile bodies? RTO

I think a more probably route would be a better, “DMZ”-like destination that is more useful than CSV.

Think, if most SaaS apps could write to Iceberg, and your CDW could read that iceberg .. each only writes 1 integration and everyone wins!
