KDE GSOC: Community Bonding and First Coding Period (May 17 - July 11)

GSOC
Of course the task I described in the last post looks and is quite monumental. That is why I laid some of the groundwork for my GSOC beforehand (in the actual German semester breaks). This work continued in the community bonding and first coding period and will therefore be described here. But first I want to thank my mentor Jasem Mutlaq for his support, his patience with me and his nerves of steel. Read more...

There are a thousand guides on how to do that, but I’ll add another one in case your setup is similar to mine. I have installed windows on a separate drive and Linux on my main drive, along with the efi partition. Don’t follow this guide blindly. Read more...

How to use the Systemd userspace DBus API on Traivis-CI

DBUS CI
I am currently working on a project which involves talking to the systemd userspace session via the session dbus instance. After some fiddling around and enabling debug mode on travis via the excellent user support, I came up with the following. Travis uses VMs that run ubuntu which comes with systemd. To enable the userspace dbus session, one has to install the dbus-user-session package. After the installation, it has to be activated through systemctl --user start dbus. Read more...
