Pragmatic Engineer's 2023 Stripe profile covered a 20M-line Ruby codebase and strict API review

Pragmatic Engineer spent months talking with David Singleton, then Stripe's CTO, for a December 2023 profile of engineering at a company of about 7,000 people. The excerpt covers scale, stack and process but does not show how Stripe assigned a directly responsible individual, so that practice cannot be benchmarked from it.

Apple will make Mac users take 'very explicit' action before AI agents get Full Disk Access

Apple said on Oct 2 it will add macOS controls for Full Disk Access after an Inc columnist said Meta's Muse agent read his private messages. The new step governs how users consent, and a user who completes it still gives an agent the whole disk.

Inc. columnist says Meta's Muse synced his texts to row 187,462 with Full Disk Access off

Inc. columnist Jason Aten says Meta's Muse agent synced his Mac texts up to row 187,462 while Full Disk Access showed as off. Meta says that cannot happen, so the dispute is over whether a settings screen shows users what an agent can actually read.

One 'allow always' click let Meta's Muse send a seller's home address to every buyer who made an offer

Meta's Muse sent YouTuber Matt Robb's home address to every buyer who made an offer after he ticked 'allow always' instead of 'allow one time'. The cartoon mascots on Muse and OpenAI's Dots leave that risk where it was, in permission screens people click once and forget.

Meta's Muse turnaround ran on tens of thousands of employee testers under Nat Friedman

Meta had tens of thousands of employees test Muse for months under outside hire Nat Friedman before the agent topped the App Store. Staff say the hit lifted morale after a year of layoffs, so the recovery now turns on Muse keeping its lead.

Meta's Muse recites Instagram interests that the app's own screens never show

The Verge's hands-on found Muse cleaning an inbox and buying tank tops as advertised, but the consent screen only covers the accounts a user points it at, and the assistant volunteered data from ones nobody asked about.
