4️⃣9️⃣ Here's the 49th post highlighting key new features of the upcoming v258 release of systemd.

One of the key features of systemd from day 1 on is socket activation, i.e. a mechanism where systemd binds sockets on behalf of services, watches them and only activates the services themselves later, possibly only at the moment they are actively used.

This has various benefits, for example reduces ahead of time cost of running a large number of services (which improves boot times).

@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

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.

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