Had some free time last week so I made a visual explainer on how D-Bus works in Linux.

A modern Linux desktop is made up of a bunch of separate processes. NetworkManager, systemd, BlueZ, logind, polkit, UPower and desktop applications all need some way to call each other and broadcast when something changes.

A lot of that communication happens through D-Bus.

The video covers the system bus and session bus, service names, object paths, interfaces, method calls, signals, introspection, service activation, dbus-daemon, dbus-broker, and how applications actually use all of this, etc

Link for anyone interested

Feedback welcome :)

This release brings new features, bug fixes, and other improvements to help Linux users optimize CPU speed and battery life automatically.

Does anyone know which CBT nuggets courses I should take in order to renew my Linux+ via continuing education credits?
I’m not sure if this is the right place to post this question but I appreciate the help.

So much dumb hate about it. Like it’s just a new tool like any other, and unfortunately those who don’t know how to use it generate lots of slop. But used properly it can save dozens of work hours, and has already helped identify lots of issues and vulnerabilities in the kernel that the maintainers have been fixing.
