This time, it’s a short one: We ported KPhotoAlbum to Qt6/KF6. That’s it ;-)

The port itself has been done by Johannes and me, additional commits have been contributed by Randall Rude and Fabian Würfl. Thanks for working on KPA with us!

One thing that’s worth mentioning is: For the map/geodata functionality, we need Marble. The Qt5/KF5 version of Marble can’t be co-installed with the Qt6/KF6 version, and this one is not released yet. But Marble 24.12.0 (which will be the first official Qt6/KF6 release) will be released in a few days. So just wait until it's out before upgrading to KPA 6, to not lose the map parts.

Maybe, the Qt6/KF6 version contains some regressions. The codebase is quite well advanced in years in some parts, and we had to mess with quite some legacy issues to make the whole thing fit for Qt6/KF6. So if you notice anything, please file a respective bug report and/or contact us via our mailing list or Matrix channel (cf. User support → Communication). Thanks for your participation (hopefully, it won’t be necessary too much).

Have a lot of fun with KPhotoAlbum 6 :-)

Pourquoi les médias devraient créer des serveurs Mastodon maintenant

Tags: tech, social-media, fediverse, bluesky, politics, business

Article in French

Very good piece explaining why the Ferdiverse is currently our only option for a decentralized social media platform. Maybe Bluesky will become another option… maybe… but so far it’s only empty promises with a real risk of capture.

If Not React, Then What?

Tags: tech, web, frontend, react, criticism, product-management, performance

Excellent piece which shows why React (or Angular) is almost always a bad choice and that you’d be better off banking on the underlying web platform. It leads to better user experience full stop. The article also goes in great length debunking the claims which keep React dominant.

Bye for now!

Lots of KDE hacking these days, and that comes with compiling large amounts of code. Right now, I am installing, well building from source Plasma Mobile on an “old” laptop so I can test some patches natively on a touchscreen device. The machine has just two cores (hyperthreaded), so builds take rather long, especially if you build Qt and all that 80+ packages that are needed for a fully working Plasma system.
One of the tools that do an incredible job while being super flexible to use is icecream. Icecream (or “icecc“) allows you to distribute your build over multiple machines, it basically ships compile-jobs with all that’s needed to other machines on a local network, meaning you can parallelize your builds.

Icecream has this nice visualization tool, called icecream-monitor which you can stare at while your builds are running (in case you don’t have anyone handy for a sword-fight). In the screenshot you can see manta, the underpowered laptop doing a 32 parallel job build over the network. miro is my heavy workstation, 8 cores and 128GB of RAM, it duely gets the bulk of the work assigned, frame is my (Framework) laptop, which is also quite beefy, gets something to do too, but not taxed as heavily as that build monster in my basement office.
Icecream can be used with most environments that have you run your compiler locally. Different distros are no problem! Just a matching CPU architecture is needed. Icecream does its job by providing its own g++ and gcc binaries, which will relay the build jobs transparently to either your local machine or across the network. So you basically install it, adjust your PATH variable to make sure icecc’s g++ is found before your system’s compiler and start your build. Other machines you want to join in for the fun just need to run icecc-scheduler and they will be automatically discovered as build slaves on your network. If you want to further speed up builds, it works with ccache as well.

Please note that you only want to do this in a trusted environment, we’re shipping executables around the network without authorization!

(originally titled “On Dead Trees”)

There’s features that you know are really important to some of our users but you frankly don’t really care for them much yourself. Printing is one such example. Recently, I actually had to print lots of paperwork, so I had a reason to fix some of my more pressing issues with our Print Manager.

The biggest regression from the Plasma 4 days, when we moved from individual System Tray popups to a unified square view, was that Print Manager had to give up its two pane layout that showed the print queue directly in the popup. In order to view and cancel print jobs, you now had to select the printer and open its print queue window, and close it again after you’re done.

Unfortunately, with printer management, there’s really two opposing use cases: a home computer with maybe a couple of printers, and the office use case of hundreds of remote printers across several buildings. Picking one side usually leaves the other one worse off. However, I did not want to spent too much time on this, so in order to fix my workflow, I simply added the list of print jobs in the expanded view. I then added a busy indicator to a printer when it’s printing to make it easier to find in the list.

CUPS error messages have never been very nice and with all that “driver-less” stuff the user experience seems to have become worse, spitting technical gibberish like “cfFilterChain: Ghost script (PID 123456)” at the user. While printing probably works better now, the overall feature set has definitely regressed for me. In order to accommodate status messages better, Print Manager now shows up to three lines of text, which is particularly important in case of a printer or network error.

Another nice little touch from Plasma 4 was a dedicated laser printer icon. At home I have a black and white laser printer for printing documents and a color inkjet for printing pictures. It’s really nice being able to tell them apart at a glance. Therefore, I added a laser printer icon to Breeze as well. However, when I investigated how it worked, I found it just assumes every black and white printer to be a laser printer. Fair enough. You can ask CUPS for the “marker type”, e.g. toner or ink, and I hoped that I could use it to determine the printer type more accurately. Alas, since updating to the Ubuntu 24.04 base, none of my printers show ink levels anymore, not even after installing the official vendor drivers. Either way, ink status has been hit or miss for me under Linux for as long as I can remember, sometimes randomly working when talking to the printer over the network but not on the computer it was plugged into via USB and so on.

Next, while tinkering with printer settings, I noticed the nice little search box we have in our settings dialogs nowadays. Trying to find a certain option, I was surprised it didn’t highlight it, even though I clearly typed the exact name on the label. You see, controls in Qt can have “mnemonics” or “accelerators”, this is the underlined letter you typically see on a button that tells you what Alt+key to use to trigger it. The letter is prefixed with an ampersand (&) in the string, so “Pap&er size” shows as “Paper size” and will trigger on pressing Alt+E. KDE applications automatically assign a free accelerators to most widgets unless explicitly provided through the ampersand notation. The settings search did not account for this and subsequently failed to find it.

Leaving the subject of printers for now, I made a few minor improvements regarding batteries. One of my earliest contributions to Plasma’s power management system over ten years ago was a notification when a peripheral device, such as mouse or keyboard, runs low on battery. While the notification showed a dedicated icon for headsets (i.e. headphones with a microphone) it did not provide one for regular headphones, and neither did battery monitor, but it was an easy fix.

Additionally, when switching output devices, a brief on screen display is shown. In case of Bluetooth devices, battery status is included alongside the device name, to quickly see when the headphones you just connected are almost out of juice. When I switched to PipeWire this stopped working, no battery percentage was shown. I didn’t fully understand how it works but with PulseAudio it probably has exclusive access to the Bluetooth device and is the one that has to read the battery information and provide it to others as audio device property. With PipeWire, I guess things are different, and I just get to read battery information over the regular BlueZ battery interface, so that’s what Plasma will consult before showing the device popup.

Finally, the Energy Information page now displays the number of charge cycles your laptop battery has experienced so far in addition to the capacity estimation (“battery health”). The ability to query this information was added to Solid, KDE’s Hardware Abstraction Framework, and is supported by all of its backends. My trusty ThinkPad has over 700 charge cycles now and still reports 77% capacity left. I was still quite happy with its battery life during this year’s Akademy – admittedly I didn’t compile much during talks and had the screen brightness very low.

Tracking library dependencies work in Debian to resolve from symbols usage to a library and add this to the list of dependencies. That is working for years now. The KDE community nowadays create more and more QML based applications. Unfortunately QML is a interpreted language, this means missing QML dependencies will only be an issue at runtime.

To fix this I created dh_qmldeps, that searches for QML dependencies at build time and will fail if it can't resolve the QML dependency.

Me didn't create an own QML interpreter, just using qmlimportscanner behind the scenes and process the output further to resolve the QML modules to Debian packages.

The workflow is like follows:

The package compiles normally and split to the binary packages. Than dh_qmldeps scans through the package content to find QML content ( .qml files, or qmldirfor QML modules). All founded files will be scanned by qmlimportscanner, the output is a list of depended QML modules. As QML modules have a standardized file path, we can ask the Debian system, which packages ship this file path. We end up with a list of Debian packages in the variable ${qml6:Depends}. This variable can be attached to the list of dependencies of the scanned package. A maintainer can also lower some dependencies to Recommends or Suggest, if needed.

You can find the source code on salsa and usage documentation you can find on https://qt-kde-team.pages.debian.net/dh_qmldeps.html.

The last weeks I now enabled dh_qmldeps for newly every package, that creates a QML6 module package. So the first bugs are solved and it should be usable for more packages.

By scanning with qmlimportscanner trough all code, I found several non-existing QML modules:

• import QtQuick3DPrivate qt6-multimedia - no Private QML module QTBUG-131753.
• import QtQuickPrivate qt6-graphs - no Private QML module QTBUG-131754.
• import QtQuickTimeline qt6-quicktimeline - the correct QML name is QtQuick.Timeline QTBUG-131755.
• import QtQuickControls2 qt6-webengine - looks like a porting bug as the QML6 modules name is QtQuick.Controls QTBUG-131756.
• import QtGraphicalEffects kquickimageeditor - the correct name is for QML6 is qt5compat.graphicaleffects, properly as it is an example nobody checks it kquickimageeditor!7.

YEAH - the first milestone is reached. We are able to simply handle QML modules.

But QML applications there is still room for improvement. In apps the QML files are inside the executable. Additionally applications create internal QML modules, that are shipped directly in the same executable. I still search for a good way to analyse an executable to get a list of internal QML modules and a list of included QML files. Any ideas are welcomed :)

As workaround dh_qmldeps scans currently all QML files inside the application source code.

The Fedora KDE SIG is pleased to announce that KDE Gear 24.12 RC (24.11.90) is available on Fedora 41 via our @kdesig/kde-beta COPR repository
