Marc Malkin, Variety:

Jessica Chastain says Apple TV is finally going to release her political thriller series “The Savant.” [...]

“Before it was like, ‘I don’t know if we’re going to see it,’ but now I can say, ‘We’re going to see it,’” Chastain told me exclusively on Saturday at the Breakthrough Prize ceremony in Santa Monica.

As for when, sources tell me that Apple is planning for a July release.

Previously, re: The Savant’s limbo release date.

WorkOS FGA: The Authorization Layer for AI Agents

workos.com/blog/agents-need-authorization-not-just-authentication?utm_source=daringfireball&utm_medium=newsletter&utm_campaign=q22026

My thanks to WorkOS for sponsoring last week at DF. Every AI agent demo looks magical, but most hit a wall in enterprise deployment. It’s not model quality or latency. It’s authorization. Authentication proves an agent’s identity. Authorization defines its blast radius.

The winners in enterprise AI won’t have the most features. They’ll be the ones enterprises can safely trust. Learn how WorkOS FGA scopes that blast radius with resource-level permissions, and read their deep dive for more.

Anthropic are the only major AI lab to publish the system prompts for their user-facing chat systems. Their system prompt archive now dates all the way back to Claude 3 in July 2024 and it's always interesting to see how the system prompt evolves as they publish new models. ...

Claude system prompts as a git timeline

Research: Claude system prompts as a git timeline

Anthropic publish the system prompts for Claude chat and make that page available as Markdown. I had Claude Code turn that page into separate files for each model and model family with fake git commit dates to enable browsing the changes via the GitHub commit view.

Bodega Cats of New York

The Bodega Cats of New York project documents the working cats of NYC’s delis, bodegas, and corner stores. The cat at the local deli wasn’t a pet. She knew the regulars. She kept the mice out. She gave people a reason to walk an extra block. And she was technically a violation of city health code. That was six years ago. Since then, the project has documented over 150 shops, collected 13,500 petition signatures, and helped introduce the first legislation in New York City history to classify bodega cats as working animals. Available soon in book form. Tags: cats · NYC · photography
