DF T-Shirts and Hoodies: Get Them While the Getting Is Good
Daring Fireball t-shirts and hoodies are back. Order now, and we’ll start printing shirts at the end of this week and shipping them out next week. The hoodies are a new model from Bella Canvas, the manufacturer. Our previous hoodies were “heather gray” and the fabric was a blend of 50% polyester, 37.5% cotton, and 12.5% rayon. That model is being phased out. So we’ve switched to a new model that’s 85% cotton, 15% polyester, and a darker “heather black” color. The old ones were good, but the new ones feel even better.

There Are Corrections, and There Are Corrections
The New York Times (gift link):
A correction was made on April 21, 2026: Because of an editing error, an earlier version of this article misstated which day the New York Mets suffered their 11th straight loss. It was on Sunday, not Monday. Even the Mets cannot lose on an off day.
This is to New York Times corrections what “Headless Body in Topless Bar” was to New York Post headlines — perfection.

Jessica Chastain Says Apple TV Will Finally Release ‘The Savant’
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
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.
