cobratbq - cranky-by-designAnyone using #debian: recent debian versions, which use #systemd, grant access to devices by way of #udev rules that add facl entries temporarily on basis of events. Debian gives or always gave hints for membership to system-groups. Almost none, certainly none for desktop use, are necessary any longer.
There are risks with groups like 'video' which grant access to /dev/fb* (framebuffers) which likely do not need user access.

SamuelMein Linux-Notebook bleibt im Performance-Modus, auch wenn ich im Zug sitze - und der Akku ist nach 90 Minuten leer.
Die Lösung: eine kleine udev-Regel, die automatisch zwischen Performance und Balanced umschaltet, sobald das Netzkabel dran oder ab ist.
Funktioniert auf GNOME, KDE und Cinnamon, also auf jedem aktuellen Ubuntu, Linux Mint oder Fedora.
Anleitung mit allen Codeblöcken im neuen Artikel auf Rüegger's Log:

Energieprofile unter Linux automatisch umschalten mit udev
Mein Linux-Notebook bleibt im Performance-Modus, auch wenn ich im Zug sitze - und der Akku ist nach 90 Minuten leer. Mit einer kleinen udev-Regel wechselt das Energieprofil automatisch, sobald ich das Netzkabel ziehe. So richtest du das auf Ubuntu, Mint oder Fedora ein.

I told Kay it was amazing to hear about the "highest ranks" of the industry from the source.
He just laughed: "Highest ranks? It was more like **Kindergarten**." 😂
Attached: A legendary selfie. Kay with the @Suse mug, me beaming, and a fellow passenger in the back blissfully sleeping through a Linux history summit. 😴
Next stop: Prague! See you all at the playground. 🇨🇿✨

GripNews🌕 Linux 硬體熱插拔事件：深入底層的技術細節
➤ 從核心廣播到使用者空間監聽的底層剖析
✤ https://arcanenibble.github.io/hardware-hotplug-events-on-linux-the-gory-details.html
當開發者需要偵測 Linux 系統中的 USB 熱插拔事件時，通常會首選 `libusb`。然而，若受限於特定應用場景無法使用該函式庫，開發者便需深入探討核心與使用者空間（userspace）之間的通訊機制。本文揭示了 `udev` 如何透過 `Netlink` 協議接收來自核心的硬體事件，並處理後續的廣播機制。作者通過剖析 `libudev` 的封包格式與 `Netlink` 運作原理，示範瞭如何直接在使用者空間監聽並解析這些底層訊息，從而繞過對高階函式庫的依賴。
+ 這篇文章真是及時雨！我之前一直以為監聽熱插拔必須依賴 libudev，沒想到透過 Netlink 處理 udev 廣播封包是完全可行的。
+ 雖然這確實提供了深入理解系統底層的機會

My game-devices-udev is missing out some udev-rules already in steam-devices. This would be a good chance to kill some time and do some MR :D (and even learn git, markdown, udev in the process!)
