@Gina yes, or you could replace the wires in that connector with longer ones. Looks like 240v? That is potentially deadly, FYI.

Got addicted to Severance on a recent flight, but I need to subscribe to 🍏 tv to see the full season now. This dystopia is getting very ~meta~ blobcatchefskiss

@jann @securepaul yep, it was hit by spam bots and I haven’t had time to clean it up.

AI agents can potentially gain extensive access to user data, and even write or execute arbitrary code.

OpenAI Codex CLI uses sandboxing to reduce the risk of buggy or malicious commands: https://github.com/openai/codex/pull/763

For now, it only blocks arbitrary file changes, but there’s room to strengthen protections further, and the ongoing rewrite in will help: https://github.com/openai/codex/pull/629

Landlock is designed for exactly this kind of use case, providing unprivileged and flexible access control.

@david_chisnall @bradley @DavyJones also, the LLM you're using for all this might be compromised.

Here's another 3D print project: a mounting bracket for W1GHZ dual-band microwave feed horns (10 GHz + 24 GHz).

Anyone using Claude for kernel / system level development? How do you make the most of it?
I like the idea of having something which can do deep code review - eg. does this code actually do what I specified? Are there any bugs? Obviously - but also not so obviously in a complex system. Have I broken layering abstractions? Is the code maintainable? What does the maintainer of this subsystem expect? Etc.

@niconiconi interesting - I guess they are old tech, so old that they may not have been imported to China at the time. You’d expect to see locally made versions though?
