Kai Uwe's Blog – Stories of a Plasma developer

Holiday Hacking

Happy holidays, everyone – I hope you can still enjoy them somewhat given the circumstances. For me it’s always a time of reflection, thinking back on the ending year. You know, I always set high standards for the work I do, I just want to put the highest quality of work out there on the interwebs, so I kinda want to write only about stuff that I’ve already uploaded some actual code for, or where I am at least confident to pull off a release soon. However, often “perfect is the enemy of good”, so I decided to just write about some of the things I did for fun over the past days. All of what you see below may or may not end up in a release at some point, or maybe or maybe not.

Plasma on the Edge

You probably have heard the news by now that Microsoft have released the Linux version of their new Chromium-based Edge web browser. Of course I’ve been waiting for this day ever since they announced the switcheroo to Chromium in order to bring Plasma Browser Integration to Edge users. It took Microsoft almost two decades to offer another web browser to a Unixoid desktop and this time around it’s based on KDE’s legacy – what a time to be alive!

Plasma Browser Integration 1.7.6

I’m pleased to announce the immediate availability of Plasma Browser Integration version 1.7.6 on the Chrome Web Store as well as Firefox Add-Ons page. This release comes with a few bug fixes, performance improvements, and translation updates.

Plasma Browser Integration bridges the gap between your browser and the Plasma desktop. It lets you share links, find browser tabs in KRunner, monitor download progress in the notification center, and control music and video playback anytime from within Plasma, or even from your phone using KDE Connect!

Virtual Plasma Sprint 2020

This weekend the Plasma team’s annual sprint took place. Due to the Corona pandemic we had to cancel our original week-long in-person meet up end of April in Augsburg, Germany hosted by our friends at TUXEDO and settled for an online sprint instead. In anticipation of more virtual sprints KDE has set up its own BigBlueButton instance – an open source web conferencing system for online learning.

Plasma @ Home

While a four day online event can’t fully replace an entire week in a room with one of the most talented and dedicated people I know hacking and discussing from 9 till midnight, I was pleasantly surprised how productive it was. Huge thanks to BigBlueButton for creating a great tool to work with and to KDE Sysadmin, and Bhushan Shah in particular, for making this happen! Also check out this lovely unprepared group photo he took.

The meeting notes are being refined a little right now and should arrive on the plasma-devel mailing list in the coming days. This week’s experience made me confident that Akademy 2020 – also happening online – will work out great! Nevertheless I hope that eventually we’ll be able to catch up on our original sprint plans and meet in Augsburg again, physically.

Sunsetting XRandR Brightness

For a change, let’s talk about a topic other than notifications. More than five years ago (can’t believe how time has passed) I took over maintainership of PowerDevil, Plasma’s power management service. While I did a lot of cleanup and feature work in the beginning, there haven’t been many major changes for some time.

One of the first features I added back then was smooth brightness changes. PowerDevil supports three ways of changing screen brightness: through XRandR configuration, through DDC (display data channel, for desktop monitors, experimental and not built by default), and by writing to sysfs (/sys/class/backlight or /sys/class/leds). Since the latter requires privileges and uses a helper binary through KDE’s KAuth framework, I only implemented the animation for the XRandR code path, which was executed in the same process.

Plasma Browser Integration 1.7.5

I’m pleased to announce the immediate availability of Plasma Browser Integration version 1.7.5 on the Chrome Web Store as well as Firefox Add-Ons page. I hope you’re all safe and well in these odd times. As you can tell from the version number this is a little more than just a maintenance release. It comes with an assortment of important bug fixes, refinements, and translation updates.

Plasma Browser Integration Itinerary Integration

(or: “How to do your project a disservice by calling it names”)

For a change, this blog post isn’t about notifications but don’t worry: there’s enough thrilling stuff to come in this area soon. Anyway, during Akademy 2019 in Milan I began adding KDE Itinerary capabilities to my pet project Plasma Browser Integration. The idea was to provide at a glance information about the subject of a website the user is currently viewing. It’s been a while since I worked on it but that of course just means that I’ve been busy doing other awesome things. ;)

Venturing out

Plasma 5.18 LTS Beta has been released, which brings many exciting new features to a computer near you, especially if you’re upgrading from our previous LTS release, Plasma 5.12. Of course for us developers this now means that a stable git branch has been created and we can work on new stuff on master to eventually become Plasma 5.19, scheduled for an early June 2020 release. This blog post is less about KDE code, though.

What’s up in Notifications?

With the end of the year approaching in some parts of the world and already half a year since I announced the notifications rewrite, I thought I’d give you an update on some of the things I’ve worked on since. While Plasma 5.17 only saw minor changes, most notably automatic do not disturb mode when screens are mirrored during presentations, there are some very exciting new features that will arrive in the upcoming Plasma 5.18 LTS to be released early February next year.

Plasma Browser Integration 1.7

I’m pleased to announce the immediate availability of Plasma Browser Integration version 1.7 on the Chrome Web Store as well as Firefox Add-Ons page. This release brings a slew of important bug fixes, translation updates, and exciting new features.
