New posts from Botmonster this week. The headline one is the Reddit verdict on Claude Opus 5: left alone for hours it is brilliant, but in a chat it buries you.

Close behind, the Pi coding agent ships with no permission system at all and runs with your full user rights, and Orca fans one prompt out to five AI coders so four of them can lose.

On the storage side, bcachefs left the mainline kernel, so we check whether it is still worth switching. There is plenty more below: a free 10-chapter AI agent book, three Btrfs jobs that stop your data rotting, a Bluetooth mesh chat that works with no internet, Rust compiled to WebAssembly, and a Home Assistant wake word that never touches the cloud.
