So, the first week of coding period has ended. It was exciting and full of challenges. I am happy that I am on the right track and making progress as I’ve promised. This is a small summary of the work done this week.

Getting rid of compiler warnings

digiKam has a really huge codebase. It is actively developed but a lot of code is old which contains deprecated Qt code which must be fixed before introducing Qt6. These are the classes which had issues in digiKam which are now fixed :-

  • QMap
  • QProcess
  • QHash
  • QMatrix
  • QLabel
  • QString
  • QFlag
  • QTimeLine
  • QTabletEvent
  • QWheelEvent
  • QButtonGroup
  • QPrinter
  • Some namespace changes like endl to Qt::endl

These patches can be found at my work branch

And these remain which I shall fix this week:

  • QSet
  • qrand() and qsrand()

Regression testing is important for my project. I patched an important class in the core of digiKam that was used by all filters in the image editor (The MR). This had a risk of introducing regression to filters. I wrote a new unit test to verify it did not.

In a nutshell, there are currently 6693 lines of build warnings on master. See this here

With the patches on my branch these warnings have reduced to 1830 lines! That’s a reduction of about 73%. See this here.

While this is not the best way to track progress but it still gives rough estimate. We now have much cleaner build outputs. This week, it will get smaller.

Thanks for reading!

Sunday, 13 June 2021

A year ago I’d just finished my History degree and I had no idea how to code. This year, I’m taking part in Google Summer of Code! I’m super happy to get the chance to learn more about how KDE software works, and to finally contribute to a project I’ve been using for years.

Over the summer, I’ll be working with KDE developers to create productivity-focused components for Plasma Mobile that work with Akonadi, KDE’s personal information management framework. Akonadi is a super useful piece of kit: it allows developers to tap into a user’s synchronised e-mails, contacts, calendars, providing a seamless experience in productivity tools. I’ll be working on this project with my mentor Carl Schwan, who also helped me during my time doing Season of KDE, and Devin Lin.

The state of affairs

Plasma Mobile is quickly shaping up to be a viable alternative to the Android/iOS duopoly, but it’s not quite there yet. KDE developers are hard at work, nailing the basics. KDE’s Plasma provides an incredibly solid foundation, though unfortunately many of the powerful desktop applications that the KDE community are not suitable for use on mobile devices.

This is mainly due to the fact they are built with a GUI framework called KXMLGui, which allows developers to create intricate and capable user interfaces for applications ranging from video editors to word processors to web browsers. Unfortunately, it’s not just made to be convergent — i.e., adaptable to different display sizes and interaction types (touch vs mouse and keyboard).

KDE’s projects are underpinned by Qt, an immensely powerful toolkit for C++ that lets you create UIs. Thanks to efforts by the Qt team, QML (a UI markup language) and Qt Quick (QML’s standard library) provide a new way of designing UIs that are built to adapt well to different device form factors. The big brained developers at KDE then developed Kirigami, a Qt Quick framework that makes it easy for a developer to bang out a pretty and convergent application usable on the desktop and on your phone (yes, this includes Android and iOS!).

However, Kirigami is still young, and the amount of applications that use it is still growing. Currently, there are a lack of productivity applications that take advantage of Akonadi.

Psst. Thinking of building a Kirigami app? Read the tutorials I wrote on KDE Develop.


Fortunately, people at KDE have already got the ball rolling. My mentor Carl Schwan started work on Kalendar, a Kirigami application that lets you display the events present in your Akonadi-synchronised calendars. However, Kalendar remains a proof-of-concept… for now.

My work for GSoC will focus on turning Kalendar into a fully-usable application that will let you view, add, and edit events in all the ways that a normal calendar application would, on both your PC and your phone. This involves figuring out how event ingestion and modification works in Akonadi, how Akonadi stores and retrieves data, and a lot of UI usability testing. By the end of the summer, we should be a lot closer to having a powerful calendar you can use with your fingertips on Plasma Mobile. 🙂

First week’s work: EventEditor merge request

In this first week, some progress has been made!

Kalendar now has an event editor sheet. While still a work-in-progress, once done, it should let you add and edit events, and let you provide dates, descriptions, reminders, attendees, and more.

Here are a bunch of screenshots of the sheet. So far, the combo boxes for the date and time fields are using custom date and time picker widgets. An upstream date picker widget should be coming in a Kirigami Add-ons package soon, and it will replace the current iteration.

This sheet is very much still a work-in-progress, from both a design and functionality perspective. So far, you can add an event through the sheet, and it will be correctly ingested into Akonadi… if you select a valid calendar (the drop-down in the event editor doesn’t make it clear which calendars are editable, yet!). You can provide an event’s name, description, start/end dates and times. The attendee, reminder, and repeat options are currently non-functional, but you can bet I’m figuring those out.

Get in touch

Feel free to reach out to me if you have any feedback, or if you just want to chat – I’m on Matrix. 😃

See you next week!

Starting with the KDE Frameworks 5.84 release, KXMLGUI based applications will feature expandable tooltips per default.

The matching merge request by Felix Ernst got merged today after 3 months ;=)

What are expandable tooltips at all?

Good question ;=)

In short: for stuff like menu & toolbar actions, it provides an easy way to access the “What’s This?” help.

Unlike before, where you need to manually trigger that via the “Shift-F1” shortcut and click around to try out which GUI elements provide at all this additional help, you will now first get a small tooltip with the normal tooltip content (if any) and a hint that with “Shift” you are able to get more help displayed.

For more details read the merge request.

A video is better than words ;=)

Felix provided a short video in the merge request to demonstrate the basic usage (based on the first implementation, some minor details got fine-tuned later).

Why is that great?

With this feature the “What’s This?” help is a lot easier to discover. It actually makes now more sense then ever to provide it for more complex actions in your applications, people will really be able to find it.

And even nicer, as this is now done in KXMLGUI, all applications using this KDE Framework will automatically provide the new feature, like e.g. Kate ;=)

Tok's welcome screen

Bon venon! Herzlich willkommen! o kama pona! Tok now has an improved welcoming sequence with improved visuals and user experience.

Tok's password screen

If you want to see this for yourself, you can now log out using the new log out menu option.

Tok's log out menu

Once you're back in Tok, why not try out the new resizable chat list?

Tok's chat list

Or the toggleable sidebar?

Tok's sidebar

Photo and Video Sidebar

Tok now lets you view photos and videos that have been sent in a chat in the sidebar.

tok photo sidebar

tok video sidebar


You might realise with the help of the sidebar that there's something inappropriate in your chat.

Now, Tok will allow you to properly delete others' messages if you have the correct permissions.

tok deletion

You can also now choose to only delete messages for yourself in groups/chats where this is applicable.

tok deletion dialog


There's a good chance you may want to scold someone for sending an inappropriate photo in your chat. Tok now provides autocompletion for mentions, making it faster to type out someone's username.

tok mentioning


Tok now supports displaying GIFs in chat.


Tok has seen a lot of optimisations. Memory usage should now hover around or below the 100MB range idle, depending on how many photos, videos, GIFs, etc. are on your screen.


A lot of Tok's crashes have been fixed, especially ones pertaining to images.

Removed unneeded drums.

This week Plasma 5.22 was released! Overall our focus on stability has paid off, and so far there are no major regressions reported; only a few medium-severity ones which have all already been fixed in Plasma 5.22.1 :). You can read the release announcement, or check out KDE developer Niccolò Venerandi’s lovely video about it:

But something much bigger happened as well: the next phase of the Breeze Evolution initiative was merged, providing a new style for buttons, menu items, checkboxes, radio buttons, sliders, and more! It’s beautiful:

This new style also fixes several bugs plaguing the old styling for these controls, such as sliders becoming invisible when located on a selected list item, and the “default button” of a dialog not being very visually obvious.

The work was implemented by Jan Blackquill in accordance with mockups made by Manuel Jesus de la Fuente and other members of the KDE VDG. It will make its debut in Plasma 5.23. There is a lot of time left to tweak the final appearance as needed, but overall I think it’s really nice and I hope you’re as excited about it as I am!

New Features

Thumbnails for files inside encrypted locations such as Plasma vaults are now generated and displayed as expected, but not saved, to eliminate a data leak (Marcin Gurtowski, Dolphin 21.08)

Kate’s LSP support now extends to the Dart programming language (Waqar Ahmed, Kate 21.08)

Konsole now supports the DECSET 1003 standard, which means that the features in terminal software such as vim which rely on mouse tracking now work (Luis Javier Merino Morán, Konsole 21.08)

This is not strictly speaking a KDE project, but it certainly affects us: the SDDM login manager can now be run as Wayland-native software without needing X11 at all! (Aleix Pol Gonzalez, SDDM 0.20)

Bugfixes & Performance Improvements

Konsole now correctly processes double right-click events (Luis Javier Merino Morán, Konsole 21.08)

emacs xterm-mouse-mode now works in Konsole (Luis Javier Merino Morán, Konsole 21.08)

In the Plasma Wayland Session, additional screens are now detected when using a multi-GPU setup (Xaver Hugl, Plasma 5.22.1)

The Network Speed widget once again works (David Redondo, Plasma 5.22.1)

The weather widget’s BBC weather data source now works again (they changed the API and we had to react to it) (Joe Dight, Plasma 5.22.1)

In the Plasma Wayland session, the transparent background beind Task Switchers is now always blurred as expected (Vlad Zahorodnii, Plasma 5.22.1)

In the Plasma System Monitor app, the “Get New Pages” view now opens in a nice overlay rather than a narrow squeezy column (Dan Leinir Turthra Jensen, Plasma 5.22.1)

Custom shortcuts for “Walk through applications” (bound to Alt+` by default) now work (Andrew Butirsky, Plasma 5.22.1)

The System Settings File Search page no longer sometimes shows a weird duplicated header (Marco Martin, Plasma 5.22.1)

The re-done Autostart page in System Settings now always shows the correct icon for applications set to run at login (Nicolas Fella, Plasma 5.22.1)

When using a lot of window rules, the System Settings Window Rules page is now much faster to load and display them (Ismael Asensio, Plasma 5.23)

Disabled pages in System Monitor no longer temporarily become un-disabled if its sidebar is collapsed into icons-only mode (Arjen Hiemstra, Frameworks 5.84)

Other User Interface Improvements

When entering Party Mode in Elisa, the playlist now automatically scrolls to the currently-playing song if it would otherwise be out of view, and also automatically scrolls the view as needed to make sure that any newly-playing songs remain in view (Tranter Madi, Elisa 21.08)

The “Get New [thing]” dialogs now handle situations like the server being down or slow more gracefully (Dan Leinir Turthra Jensen, Frameworks 5.84):

QtQuick apps using the Kirigami OverlaySheet component no longer let the sheet touch the edges of the window or screen (Devin Lin, Frameworks 5.84)

…And everything else

Keep in mind that this blog only covers the tip of the iceberg! Tons of KDE apps whose development I don’t have time to follow aren’t represented here, and I also don’t mention backend refactoring, improved test coverage, and other changes that are generally not user-facing. If you’re hungry for more, check out, where you can find blog posts by other KDE contributors detailing the work they’re doing.

How You Can Help

Have a look at to discover ways to be part of a project that really matters. Each contributor makes a huge difference in KDE; you are not a number or a cog in a machine! You don’t have to already be a programmer, either. I wasn’t when I got started. Try it, you’ll like it! We don’t bite!

Finally, consider making a tax-deductible donation to the KDE e.V. foundation.

Friday, 11 June 2021

We are pleased to announce that Plasma 5.22.0, is now available in our backports PPA for Kubuntu 21.04 Hirsute Hippo.

The release announcement detailing the new features and improvements in Plasma 5.22 can be found here.

To upgrade:

Add the following repository to your software sources list:


or if it is already added, the updates should become available via your preferred update method.

The PPA can be added manually in the Konsole terminal with the command:

sudo add-apt-repository ppa:kubuntu-ppa/backports

and packages then updated with

sudo apt full-upgrade


Please note that more bugfix releases are scheduled by KDE for Plasma 5.22, so while we feel these backports will be beneficial to enthusiastic adopters, users wanting to use a Plasma release with more rounds of stabilisation/bugfixes ‘baked in’ may find it advisable to stay with Plasma 5.21 as included in the original 21.04 (Hirsute) release.

The Kubuntu Backports PPA for 21.04 also currently contains newer versions of KDE Frameworks, Applications, and other KDE software. The PPA will also continue to receive updates of KDE packages other than Plasma.

Issues with Plasma itself can be reported on the KDE bugtracker [1]. In the case of packaging or other issues, please provide feedback on our mailing list [2], IRC [3], and/or file a bug against our PPA packages [4].

Let’s go for my web review for the week 2021-23.

We’re All Paying for Someone Else’s 4-Hour Work Week, Not Ours | by Jessica Wildfire | May, 2021 | An Injustice!

Tags: economics

I read that book out of curiosity a long while ago. This post articulates quite well why I hated it. It’s built upon selfishness and inequalities.

Don’t let Social Media Think for You

A good illustration on why social media are toxic for our thinking. They push us to focus on anecdotes and as such miss the big picture. No wonder everything got so polarized so quickly there.

Very important open letter, this kind of biometric surveillance is becoming pervasive and should be stopped earlier than later.

Very interesting discussion about decision making and forecasting. I’m discovering Tetlock as he is mentioned and his findings are interesting in their own right as well.

Last part about estimates. Plenty of very good advises again on how to deal not meeting a deadline. Communicating the bad news early is key.

Stockdale Paradox — Why optimists don’t survive software projects | by Ben Hosking | Jun, 2021 | Dev Genius

Excellent advises on project planning and management. It explains pretty well why being optimist in those areas will just drive your project through a wall.

Bye for now!

In mid-2014 I first heard about Jolla and Sailfish OS and immediately bought a Jolla 1; wrote apps; participated in the IGG campaign for Jolla Tablet; bought the TOHKBD2; applied for (and got) Jolla C.

Sounds like the beginning of a good story doesn’t it?

Well, by the beginning of 2017 I had sold everything (except the tablet, we all know what happened to that one).

So what happened?? I was a happy Sailfish user, but Jolla’s false promises disappointed me.

Yet, despite all that, I still think about Sailfish OS to this day. I think it’s because, despite some proprietary components, the ecosystem around Sailfish OS is ultimately open source. And that’s what interests me. It also got a fresh update which solves some of the problems that where there 5 years ago.

Nowadays, thanks to the community, Sailfish OS can be installed on many devices, even if with some less components, but I’m looking for that complete experience and so I asked on the forum if there was someone willing to sell his Xperia device with or without the license… and I got one for free. Better still, in exchange for some apps!

To decide which applications to create, I therefore took a look at that ecosystem. I started with the apps I use daily on Android and looked for the Sailfish OS alternative (spoiler: I’m impressed, good job guys!).

I am writing them all here because I am sure it will be useful to someone else:

  • AntennaPod (podcast app) -> PodQast
  • Ariane (gemini protocol browser)
  • AsteroidOS (AsteroidOS sync) -> Starfish
  • Connectbot (ssh client) -> built-in (Terminal)
  • Conversation (xmpp client) -> built-in (Messaging)
  • Davx5 (caldav/cardav) -> built-in (Account)
  • DroidShows (TV series) -> SeriesFinale
  • Element (Matrix client) -> Determinant
  • Endoscope (camera stream)
  • Fedilab (Mastodon client) -> Tooter
  • ForkHub (GitHub client) -> SailHub
  • FOSS Browser -> built-in (Browser)
  • FreeOTP -> SailOTP
  • Glider (hacker news reader) -> SailHN
  • K-9 Mail -> built-in (Mail)
  • KDE Connect (KDE sync) -> SailfishConnect
  • Keepassx (password manager) -> ownKeepass
  • Labcoat (GitLab client)
  • Lemmur (Lemmy client)
  • MasterPassword (password manager) -> MPW
  • MuPDF (PDF reader) -> built-in (Documents)
  • Newpipe (YouTube client) -> YTPlayer
  • Nextcloud (Nextcloud files) -> GhostCloud
  • Notes (Nextcloud notes) -> Nextcloud Notes
  • OCReader (Nextcloud RSS) -> Fuoten
  • OsmAnd~ (Maps) -> PureMaps
  • Printing (built-in) -> SeaPrint
  • QuickDic (dictionary) -> SailyDict
  • RedMoon (screen color temperature) -> Tint Overlay
  • RedReader (Reddit client) -> Quickddit
  • Signal -> Whisperfish
  • Syncthing (files sync) -> there’s the binary, no UI
  • Transdroid (Trasmission client) -> Clutch
  • Vinyl (music player) -> built-in (Mediaplayer)
  • VLC (NFS streaming) -> videoPlayer
  • WireGuard (VPN) -> there’s the binary, no UI
  • YetAnotherCallBlocker (call blocker) -> Phonehook

So, to me it looks like almost everything is there, except:

I’ve already started to write a UI for Syncthing, then maybe I could write the browser for the gemini protocol or rather the GitLab client?

Many many thanks to Jörg who sent me his Sony Xperia 10 Plus! I hope I don’t disappoint him!
