## Worth attention

- **It's dead, Jim! (UEFI CA expiry)**
  https://blog.einval.com/2026/06/27#its_dead_jim
  The Microsoft UEFI CA from 2011 expired on June 27, 2026, and distro maintainers are now rolling out dual-signed shim binaries plus fwupd changes so Secure Boot systems keep booting cleanly. This matters because the rollover itself is done, but machines that miss the updated shims or firmware DB/KEK updates can fail later. If you maintain Linux fleets or personal Secure Boot machines, make sure current shim and fwupd updates are applied.
- **Show HN: Adrafinil – keep a lid-closed Mac awake only while agents work**
  https://github.com/kageroumado/adrafinil
  Adrafinil is a macOS utility that blocks lid-closed sleep only while an AI coding agent is actively working, then releases the hold automatically when the agent goes idle. The practical value is operational: it fixes a real annoyance for local agent workflows without forcing users to babysit Amphetamine or leave laptops half-open. If you run long local agent jobs on a MacBook, this is worth testing; otherwise it is just a neat niche tool.
- **Pollen tried to remove my article about Callum Negus-Fancey, and Google is assisting to it**
  https://blog.pragmaticengineer.com/pollen-tried-to-remove-my-article-about-callum-negus-fancey-and-google-is-assisting-to-it/
  Gergely Orosz says Google removed his original reporting on Pollen after a bogus copyright claim that falsely alleged it copied an unrelated 1998 New York Post article. The immediate lesson is not about Pollen itself but about how easy it still is to abuse takedown systems to bury accurate writing. Monitor this as a reputation and discoverability risk if your business depends on search visibility or publishing critical reporting.
