- Uplift your Linux systems programming skills with systemd and D-Bus Practical examples and best practices on how to leverage systemd and D-Bus in Go

Systemd is a de-facto standard process manager in all mainstream Linux distributions for almost a decade.
D-Bus is most widely used inter-process communication on a local host. It's used in many core apps on Linux Desktop.
Yet both systemd and D-Bus are undervalued.
Very often, programs that are only intended to run on Linux attempt to re-implement (with bugs) what systemd and D-Bus already provide
(for example: watchdog function, reliable process termination, notifying another program about some event, coordination between multiple processes).
The goal of this talk is to shift perspective on systemd and D-Bus (using concrete practical examples in Go),
and show how basic building block these systems provide can be re-used in software you write for modern Linux system.
This is an exploratory talk. Then intent is to look at systemd and D-Bus from a different angle.
Most of current tutorials about systemd focused on operating a service like apache, nginx or redis.
D-Bus tutorials are very abstract, basic and lack any concrete useful use-cases.
I plan to present few recent additions to systemd, such as portable services and resource control.
As well as re-introduce few existing concepts, like sd-notify, watchdogs and transient units.
On D-Bus I plan to show how to use bus abstraction and few neat features,
like passing file descriptors and receiving notifications.
The focus is on how to not re-invent things that systemd and D-Bus do much better.
Examples are given as a few simple Golang programs, with full source available on ❮a href="github.com/lvs..."❯github❮/a❯.
The indented audience is anyone who write and operate Go code on Linux.
Preferred experience of the audience: basic knowledge of Linux and Golang, familiarity with systemd and D-Bus concepts would be useful as well.

Nice intro to DBUS. Note to viewers - The PPT is shown in full screen from the 5 minute mark onwards.
Can you please put the slides on the large screen... there's absolutely no chance that it's readable on the small thingy, that's where the speaker belongs, not the content
Did you watch past 5 minutes? the slides are placed on large screen after 04:45 .. geez
@@reeldeelz2940 IKR?
The video snippet should be swapped
Excellent
dbus looks way less cool than I had expected lol
Very junior photographer.
what exactly do you mean. gopher is right in centre frame. no problems there.
How old are this? Pre covid?
The date is given at the beginning of the video. This was held on 2nd February 2020.
