Theme of the day: The harness wars get serious. Agentic coding stops being a vibe and starts being engineering — with receipts, attacks, and the first real maintainer pushback.

SSH key rotation guide: secure backup of ~/.ssh with 7zip (AES-256, encrypted headers), safe SSH key revocation without lockout, correct order to replace keys, behavior of active SSH sessions, authorized_keys handling, fixing broken ~/.ssh permissions, ed25519 keys, OpenSSH on Linux/macOS, real-world DevOps and server security notes.

Since I record my screen a lot for videos and courses, I need to take some security measures more frequently than the average person. Because I recently recorded a few videos teaching Linux server security, I ended up showing some SSH private and public keys on screen.
There’s nothing critical here. Those were temporary keys. Still, just to be safe, I’m rotating all my SSH keys.
