Welcome to the new home of "This Week in Plasma"! No longer is it a private personal thing on my (Nate Graham's) blog, but now it's a weekly series hosted here on KDE's infrastructure, open to anyone's participation and contribution! I'll remain the editor-in-chief for now, and welcome contributions via direct push to the relevant merge request on invent.kde.org. And after a post is published, if you find a typo or broken link, feel free to just fix it.
The OOM killer always, invariably starts off with killing the display server. Any side effects such as “the notification daemon loses its connection and closes” or “every single thing that you were working on loses its connection and closes” is incidental.
