- Week 1 of Season of KDE 2026 (2026/02/02 17:36)Hello everyone!🎉 Welcome to my first blog! I am Sayandeep Dutta, an undergraduate at SRM University. I learned about the awesome mentorship program, Season of KDE. Getting StartedI started contributing to Mankala in December 2025. Got to know more about the project, interacted with mentors, and started with some small merge requests. I really like contributing to Mankala. Mankala has been a very interesting game, and the guidance from the community is really good. Week 1: Development & DesignIn my first week, I had set up Mankala on my Ubuntu machine and started with the development. I created mockups for the proposed UI changes in MankalaNextGen. The mockups mainly included the main game page, a login page, a home page, and some other pages in the game, which were created and worked upon by me on Figma. Progress So FarI had created a merge request updating the MainMenu. Well, there are a couple of pages and components we need to work on, and the Main Menu is the most essential one to start with. What's next?In the upcoming week, I plan to: Complete the rest of the UI updates. Start implementing the new theme of MankalaNextGen. Thanks for reading. Stay tuned for more updates. 👀
- Poor Man's Volumetric Light (2026/02/02 10:42)Building Volumetric Light Shafts with Real IES Profiles You know that feeling when the street lamps on a hazy evening cast these particular patterns of light? I've always been fascinated by those effects, so I decided to build a real-time volumetric lighting system using Qt 6.11's graphics capabilities, leveraging its QML shader integration and 3D rendering pipeline to recreate them with actual IES profiles. Streetlight patterns in the evening haze
- Season of KDE 2026: Week 1 Progress for Automating Promo Data Collection (2026/02/01 00:00)Hi all! I'm CJ, and I'm participating in Season of KDE 2026 by automating portions of the data collection for the KDE promo team. This post is an update on the work I've done in the first week of SoK. My mentor gave me a light task to help me get set up and familiarize myself with the tools I'll be using for the rest of the project. The task was to automate the population of a spreadsheet that tracks follower and post counts for X (formerly known as Twitter), Mastodon, BlueSky, and Threads. The spreadsheet takes the follower and post counts of some of KDE's social media platforms and makes calculations based off that data. Important things to note: data from the sites is entered manually there are a lot of styles and formulas in the sheet Fetching Account Data Grabbing data was mostly no trouble. Mastodon and BlueSky were especially easy to work with. They have a public and well documented API that lets people collect all kinds of data in human-readable formats. One particular endpoint from both sources output account information, including follower and post counts, for a given account in neat JSON files (BlueSky, Mastodon). All it took were GET requests to these endpoints and it was smooth sailing. X and Threads proved a bit more finnicky. Both of their APIs limit access to much of their functionality usually meaning webscraping methods are the most accessible for grabbing public account data. Threads shows users' follower counts out directly on an account's landing page, so processing a GET request to the URL of KDE's Threads account made it easy to grab. The problem is that there seems to be no direct way to grab the post count either through their API or with webscraping methods. For now, we've chosen to leave that be and circle back when I explore Threads more in the future. X presents a similar problem but there is an open-source frontend alternative named Nitter, instances of which lay all the stats information out in the open. The reliability of this method depends on public Nitter instances being available so it may be worth coming back around to this in a later part of the project, but for now it's a viable solution for getting follower and post counts. Inputting the Data Into the Spreadsheet With the data all fetched, all that was left is to add that data to the ODF spreadsheet. I had this down as the easy part of the task but in the end it wasn't so simple. The two major Python packages I found that can interpret and write ODF files: Pandas and pyexcel. Both of these have no problem reading data from the files, but when it comes to saving they don't preserve some elements of the spreadsheet. In the end we went the simple route which is to save the data to a separate ODF file using one of the Python-ODF interfaces and import that into the data sheet. This took a little finagling with formulas to get things working without popping errors into cells the sheet, but in the end we have an output ODF spreadsheet file containing the required data and the original spreadsheet with all the calculations pulling that data into its formulas, removing any requirement of a human interfacing with this portion of data collection. Learned Lessons I feel like this week's task was a great first step into data collection automation. It was challenging without being too difficult to make progress on and forced me to explore different avenues for gathering data. On the confidence side, getting a (mostly) successful task out the gate helped me feel more comfortable with the tools and processes that will likely appear throughout the entirety of my SoK experience. Things will scale up from here on out though so I'm also keeping myself in check. From what I understand some of the most difficult parts of automated data collection come through having to interface with Javascript and not getting banned, both of which I've yet to come face-to-face with in any substantial capacity so far. Along with that I've face unexpected problems, such as the issue with modifying ODF files and that some websites don't play as well with certain browsers, which I don't have an easy way to test for yet. With these in mind I'm trying to tread lightly and be diligent with research and good practice as I continue on.
- This Week in Plasma: getting 6.6 ready for release (2026/01/31 00:03)Welcome to a new issue of This Week in Plasma! This week we reached that part of every Plasma release cycle where the bug fixes and polish for the upcoming release are still coming in hot and heavy, but people have also started to land their changes for the next release. So there’s a bit of both here! Everyone’s working really hard to make Plasma 6.6 a high-quality release. It’s a great time to help out in one way or another, be it testing the 6.6 beta release and reporting bugs, or triaging those bugs as they come in, or fixing them! Notable New Features Plasma 6.7.0 The Emoji Selector window now lets you choose mixed skin tone groupings of emojis using a nice little user-friendly pop-up dialog. (Tobias Ozór, plasma-desktop MR #3426) After Before You’re now able to set a global keyboard shortcut to clear the notification history. (Taras Oleksyn, KDE Bugzilla #408995) Notable UI Improvements Plasma 6.6.0 In the Application Dashboard widget, keyboard focus no longer gets stolen by selectable items that happen to be right under the pointer at the moment the widget is opened. (Christoph Wolk, KDE Bugzilla #510777) Breeze-themed checkboxes now always have an opaque background, which resolves an issue where their unchecked versions could be hard to see when overlaid on top of images. (David Redondo, KDE Bugzilla #511751) Plasma 6.7.0 System Settings’ subcategory back button is now more of a traditional back button, eliminating a source of redundant page titles. There are still too many, but this reduces the count by one! (Nate Graham, systemsettings MR #390) After Before On System Settings’ Notifications page, you can now always preview a notification sound even if sound is currently disabled for that notification. (Thomas Moerschell, plasma-workspace MR #6214) Plasma’s network settings now expose additional L2TP VPN options that were previously unavailable. (Mickaël Thomas, plasma-nm MR #480) The old Air Plasma style (a lighter take on the original Oxygen style) is back, with fixes and improvements, too! (Filip Fila, oxygen MR #77) The Oxygen cursor theme received a small visual fix to improve the appearance of the busy cursor. (Filip Fila, oxygen MR #89) The cursor theme settings now show more accurate previews, which fixes issues like wobbling cursors, and makes the preview grid feel more stable. (Kai Uwe Broulik, plasma-workspace MR #6240) System Settings’ various theme chooser pages are now consistent about whether you can delete the active theme (no), and also let you know why certain themes can’t be deleted: because they were installed by the OS, not the “get new stuff” system. (Sam Crawford, plasma-workspace MR #6222) The Weather Report widget now shows a progress indicator while its popup is open but still loading the weather forecast from the server. (Bogdan Onofriichuk, kdeplasma-addons MR #993) Frameworks 6.23 Combobox pop-ups through QtQuick-based apps and System Settings pages now use the standard menu styling, rather than a custom style. (Nate Graham, qqc2-desktop-style MR #497) After Before Added styling for the new upstream SearchField component that was recently added to QtQuick itself. Now it looks like the KDE version that we created years ago before the Qt version existed. (Manuel Alcaraz Zambrano, qqc2-desktop-style MR #500) Notable Bug Fixes Plasma 6.5.6 Fixed an issue on operating systems with asserts turned on (like KDE neon) that could sometimes crash Plasma when you launched apps. (David Edmundson, KDE Bugzilla #513312) Plasma 6.6.0 Fixed a rare issue that could leave KWin without control of the mouse and keyboard at login. (Vlad Zahorodnii, KDE Bugzilla #511611) Fixed a case where Plasma could crash when moving around a Weather Report widget on the desktop. (Bogdan Onofriichuk, KDE Bugzilla #514200) Fixed an issue in Discover when launched with Snap support that could prevent it being launched again after previously being closed. (Aleix Pol Gonzalez, KDE Bugzilla #507217) Fixed a case where the Plasma Bluetooth pairing wizard would fail to pair devices. (David Edmundson, KDE Bugzilla #495615) The logout screen no longer fails to take focus if you raised the focus stealing level to “Medium” or higher, and manually de-focusing it no longer breaks your ability to re-focus it. (Vlad Zahorodnii, KDE Bugzilla #514204 and Aleksey Rochev, KDE Bugzilla #511258) The custom size ruler for Plasma panels no longer sometimes appears on the wrong screen of a multi-screen setup. (Vlad Zahorodnii, plasma-workspace MR #6215) The “X notifications were received while Do Not Disturb was active” notification is no longer inappropriately saved to the notification history. (Kai Uwe Broulik, plasma-workspace MR #6223) Fixed two semi-related issues with widgets that made them not let you pick the same color after deleting it, or configure the same mouse action after deleting it. (Christoph Wolk, KDE Bugzilla #514983 and KDE Bugzilla #449389) The global menu on a newly-cloned panel on a different screen now realizes immediately that it’s on a new screen. (David Redondo, KDE Bugzilla #514907) Discover’s notification about ongoing updates no longer displays a nonsensically large number of updates under certain circumstances. (Harald Sitter, KDE Bugzilla #513676) Plasma Browser Integration no longer exports Microsoft Teams calls as controllable media sources; it always omitted them in the past, but Microsoft changed the URL again, so we had to adapt to that once more. (Kai Uwe Broulik, KDE Bugzilla #514870) You can now move focus from the Application Dashboard widget’s search field using arrow keys, and also type accented characters using dead keys or the compose key as the first character in a search while the search field isn’t explicitly focused. (Christoph Wolk, KDE Bugzilla #511146 and KDE Bugzilla #510871) Animated wallpapers explicitly set for the lock screen now play their animation as expected. (Taras Oleksyn, KDE Bugzilla #460910) Undoing the deletion of a panel widget no longer sometimes positions it far from where it was before. (Marco Martin, KDE Bugzilla #515107) Ending the renaming of an item on the desktop by clicking on another item no longer starts a drag-selection for no good reason. (Akseli Lahtinen, KDE Bugzilla #514954) The “Defaults” button on System Settings’ Accessibility page now works properly to reset non-default colorblindness modes. (Andrew Gigena, KDE Bugzilla #513489) Plasma 6.7.0 Fixed a very nasty KWin bug that could, under certain rare circumstances relating to intensive Alt+Tab usage, cause the screen to go black. This change may be backported to Plasma 6.6 if it’s deemed safe enough. (Xaver Hugl, KDE Bugzilla #514828) Frameworks 6.23 Fixed being unable to paste clipboard entries as text that were copied from a LibreOffice Calc spreadsheet cell and then re-arranged in the clipboard history list. (Alexey Rochev, KDE Bugzilla #513701) Notable in Performance & Technical Plasma 6.6.0 KRDP (the KDE library for remote desktop support) no longer requires systemd. (David Edmundson, krdp MR #141) Plasma 6.7.0 KWin now supports the ext-background-effect-v1 Wayland protocol. This adds support for standardized background effects like blur, opening the door for visual consistency across apps using these effects.

- KWallet, SecretService, oo7: the story so far (2026/01/30 16:15)Continuing previous efforts to update the “secure passwords” story of the Plasma desktop, I’ve done some integration work between Plasma and oo7. Oo7 is a relatively recent SecretService provider written in Rust; it’s very nice, lightweight and cross-desktop. Very interesting for us supporting it as a first class citizen. We want in the end to replace completely the old KWallet system with something based on SecretService, have all our applications migrated transparently with user data as well, if possible with a cross-desktop backend implementation. We also want it to be as transparent as possible for the end user, not having any complicated first time setup, or dialogs that ask for a manual unlock when not needed. For the user, the whole system should be just invisible, except when looking up their passwords or when client applications add passwords to it themselves. As a first thing several months ago we did a transparent translation layer for the KWallet DBus interface, so now the “KWallet” service became just a translation layer between the kwallet api and the secretservice one. The old kwalletd service instead became “ksecretd” now providing only the SecretService interface, and that’s what we use by default now. however, it can be configured to use a different provider, so it can already be used with gnome-keyring or KeepassXC if the user wishes. In that case the user data will be migrated the first time. Also I’ve written a new application called KeepSecret. It is centered around SecretService, with a much more modern UI compared to KWalletManager and works also much better on mobile, so we can have also a modern password manager on Plasma Mobile. KeepSecret running with the oo7 backend, with a native password dialog The last thing that we did so far is integration with a new SecretService provider on the block: oo7. If oo7 is Just another SecretSerive provider, Won’t it “just work” in Plasma? Not quite, but that’s actually a good thing. Oo7 wants to properly integrate with the environment it runs in, so we need to build that integration. When you use KWallet, KeepassXC, or gnome-keyring directly, they create their own password dialogs using their own toolkits and styles, therefore potentially looking a bit alien when run in a different environment than the one it it was designed for. This is not ideal for evaluating options for a possible future replacement of KWallet (which piece by piece we are working towards), as we want the UI part completely integrated with the Plasma desktop. Instead, oo7 is built on the assumption that the environment it runs on will provide its own dialogs, a bit like the portal system for services like screen sharing and file picking.This requires active integration both on the Plasma part and the oo7 part, but on the other hand it will look native on Plasma, Gnome, and any other platform that implements the integration hooks. And that’s with the added benefit of sharing the password storage if someone every now and then goes desktop environment hopping. On the Plasma side we decided to employ a very small daemon which is launched only on demand with dbus activation. It will create the needed system dialogs, pass the user input back to oo7 and then quit when not needed anymore, so it won’t constantly use up system resources. This is already available in Plasma 6.6: the code for it is here. It’s designed first for oo7, but it can be used by any daemon which wishes to provide native password dialogs, so we might start to use it also from other components in the future, either other SecretService providers or completely different things which have similar needs like Polkit. On the oo7 part, Harald implemented the integration with its dbus interface, so with oo7 from main branch (or its next release) it can be used in place of KWallet (with all old applications still using the KWallet API using its backend as well), with all data migrated to it, and it will show native UI for its password dialogs… all the pieces of the puzzle slowly falling together Needless to say this is still at an experimental stage, but it’s an important milestone in getting more independent from the aging KWallet infrastructure.

Unsurprisingly this didn’t go well and they had to cover their tracks several times. The response from the Matrix foundation is a bit underwhelming, it’s one thing to be welcoming, it’s another to turn a blind eye to such obvious failures.

- December/January in KDE Itinerary (2026/01/30 08:45)In the past two months since the previous report KDE Itinerary got new vector-based map views and manual control over reservation cancellations, and there has been more work on reverse engineering proprietary train tickets, among many other things. New Features Vector maps The map views can now use a MapLibre-based vector map instead of the previous raster image map. This gives us smoother and continuous zoom, and should also allow localized labels eventually, something particularly important in regions you can’t even read the local script. Vector-based map view in Itinerary. This is enabled in our nightly APK and Flatpak builds, other distribution channels might not have this enabled yet. Reservation cancellation It’s now possible to manually mark reservations as canceled, rather than just importing that information from documents. This is useful for keeping unused reservations around but not have them considered for transfers, in the maps or for statistics, e.g. because you still need them for refund claims or travel cost reimbursement. Manually changeable cancellation status. Canceled reservations are now also clearly marked as such in the timeline view again, something that had gotten lost in the last timeline restyling. Infrastructure Work Ticket barcode reverse engineering Ticket barcodes can contain machine-readable information about the trip and can therefore be very useful for importing tickets into Itinerary. While ticket barcodes on international trips commonly use openly standardized formats for interoperability between different providers, this is unfortunately often not the case for domestic tickets. For those we have to resort to reverse engineering. Fortunately though, there’s more people interested in what’s in those barcodes, e.g. from a privacy or security perspective, and there’s increasing collaboration. Specifically, the understanding of the Hungarian domestic ticket format has significantly increased recently, as the result of three different parties exchanging their observations and evaluating their respective findings against each other’s ticket sample pools. A few few magic numbers for product/tariff/discount codes are yet to be figured out, but there’s now a pretty complete Kaitai spec able to decode versions 2 to 6 of the current format, e.g. using the Kaitai Web IDE. Many of the discoveries made there have a resulted in improvements and fixes for MÁV and Volánbusz tickets in Itinerary. Documentation on ticket barcodes formats is also slowly being consolidated in the Train Ticket Wiki, where available also in appropriate machine-readable formats (Kaitai, Protobuf, ASN.1, etc). Reverse geocoding for location codes The work on automatic geocoding for train and bus reservations covered in the last report has been further expanded: Hotel and restaurant reservations are now also automatically geocoded. This makes automatic transfers work in more cases. Reverse geocoding on imported tickets only containing train station or airport codes is now also supported. This for example results in proper station names when scanning a train ticket barcode that only contains station codes. Events There’s two recent events that covered upcoming changes to Transitous, the public transport routing service used by Itinerary: 39C3 end of 2025. The Transitous Hack Weekend a few weeks ago. And more opportunities to meet the Itinerary and Transitous teams are coming up: FOSDEM on Jan 31-Feb 1 in Brussels, in particular with the Railways and Open Transport track. The next bi-annual OSM Hack Weekend in Karlsruhe on Feb 21-22. FOSSGIS-Konferenz on Mar 25-28 in Göttingen. I’ll talk about our OSM indoor router there. The KDE Mega Sprint on Apr 6-11 in Graz right before Grazer Linux Tage will probably also include some Itinerary hacking. Fixes & Improvements Travel document extractor Added or improved travel document extractors for Booking.com, České dráhy, Cytric, Deutsche Bahn, gomus, KLM, MÁV and Volánbusz. Fixed a crash on referenced but non-existent PDF image masks (bug 513945). Handle RSP6 decoding failures properly, fixing a few fields containing “null” in that case. Added support for resolving Hungarian railway station codes. Added support for local SNCF pass barcodes in some regions of France. All of this has been made possible thanks to your travel document donations! Public transport data Added (partial) coverage in Japan and Thailand thanks to Transitous. Fixed access parameters to the VVS API for the Stuttgart area in Germany. All of this also directly benefits KTrip. Itinerary app Mark cancelled intermediate stops on the journey section map. Don’t allow to open an empty place context menu. Show yearly sections for past trip groups in the trip group list. Fix showing entrance date picker for events without valid start date. Fix a timer overflow when monitoring for delays for trips in the slightly more distant future. Fixed several issues following from inconsistent ordering of timeline entries, such as two elements starting at exactly the same time and having no defined end time. This could reesult in duplicate or lost timeline entries under some circumstances. Correctly reset the trip group name field after closing the rename dialog. Fix overly aggressive input validation on manually entered flight numbers. Continous Flatpak builds for testing the latest development version are now also available for ARM64. How you can help Feedback and travel document samples are very much welcome, as are all other forms of contributions. Feel free to join us in the KDE Itinerary Matrix channel.

- Kaidan 0.15.0: Audio/Video Calls and Integrated Search Field (2026/01/29 23:00)Welcome Kaidan 0.15.0! This release adds experimental support for calls. In addition, it contains some very useful improvements and lots of fixes. Most of the work has been funded by NLnet via NGI Zero Entrust and NGI Zero Commons Fund with public money provided by the European Commission. Audio/Video Calls Kaidan has supported voice and video messages for a long time. Starting with this release, you can even have an audio or video call with a contact! An incoming call is indicated via a notification and you can either accept or reject it. Please note that there are still some features missing and some setups may not work properly. Especially, calls are only supposed to work on Linux at the moment. But wee wanted to share the current achievements with you to get some feedback! Our goal is to extend the A/V calls functionality and make it available on other operating systems in the future. Notifications for Group Chat Replies Formerly, you got a notification if someone mentioned you in a group chat while the corresponding setting was enabled. But you could miss replies to your messages. Kaidan notifies you now on receiving replies as well. Message Input Field Focusing In contrast to the soft keyboard on a mobile device, which needs to be opened each time you want to enter something, your keyboard is always reachable on a desktop device. Why not make use of that circumstance? Kaidan ensures that the most relevant message input field stays focused to allow entering text without an additional click into the corresponding field. That way, you can interact smoothly with the user interface and be more productive. Advanced Message Highlighting Kaidan 0.14 introduced highlighted messages if you opened their context menu. Messages are now also highlighted while they are being corrected or while you are choosing emojis to react to them. If another message was already highlighted before, that message is highlighted again once you sent the correction/reaction. Integrated Search Field With Kaidan, you can quickly search for chats and messages. But while searching for messages, the opened search bar reduced the space for messages. On mobile devices, the search bar even consumed unnecessary space within the chat list. Both problems are solved now! The search field is integrated into the main toolbar above the messages resp. the chat list. You can even focus each search field via an own keyboard shortcut to directly search without moving the cursor. Password Manager Fallback Since Kaidan’s last version, passwords are stored in a password manager if the system provides one. But there was no fallback yet. It is now possible to use Kaidan even if no password manager is available. In that case, the passwords are stored in an unencrypted file.

- Ooo, what does this disk do? (2026/01/28 23:00)I have a pile of hard drives. 3.5” Spinning rust. There’s like a dozen of them, some labeled cryptically (EBN D2), some infuriatingly (1) and some not-at-all. Probably most of them work. But how to effectively figure out what is on them? FreeBSD to the rescue. Hotplug Just Works All the drives are SATA. I do have an IDE drive, I use it for opening beer bottles. And an ST-225 for old-time’s sake. But SATA it is, and there’s spare SATA data- and power-cables dangling out the side of my PC. This particular machine runs FreeBSD 14.3, and connecting a drive (data first, then power) yields some messages in the system log. Old-school, the command to read these is still dmesg, which prints: ada3 at ahcich0 bus 0 scbus0 target 0 lun 0 ada3: <WDC WD3200AAKS-00SBA0 12.01B01> ATA-7 SATA 2.x device ada3: Serial Number WD-WMAPZ0561055 ada3: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes) ada3: Command Queueing enabled ada3: 305245MB (625142448 512 byte sectors) That matches information printed on the label of the disk (this drive is from 2007, has a 1 written on it in black marker – it may have been a drive in the English Breakfast Network server back then). It also tells me that the disk is registered with the system as ada3. FreeBSD’s disk subsystem is a stack of “GEOM classes”. The geom(4) manpage tells me that it is a modular disk I/O request transformation framework, but the important bit is geom(8), the command to query the disk subsystem. Running geom disk list ada3 tells me what is known about disks involved with ada3. This actually doesn’t tell me much I don’t already know: Geom name: ada3 Providers: 1. Name: ada3 Mediasize: 320072933376 (298G) Sectorsize: 512 Mode: r0w0e0 descr: WDC WD3200AAKS-00SBA0 lunid: 50014ee0aabd8fe3 ident: WD-WMAPZ0561055 rotationrate: unknown fwsectors: 63 fwheads: 16 Well, actually this tells me that the dmesg and geom output are in mibi- and gibi-bytes, and that they’re consistent. How about partitions on this disk, though? geom part list ada3 tells me (here I’ve removed several partitions, along with many other lines that are not very useful right now; the output is extensive): Geom name: ada3 scheme: GPT Providers: 1. Name: ada3p1 Mediasize: 819200 (800K) efimedia: HD(1,GPT,a43a2da3-bb5f-11e5-8d81-f5e4d894ddb1,0x22,0x640) label: (null) type: efi index: 1 2. Name: ada3p2 Mediasize: 315679277056 (294G) efimedia: HD(2,GPT,a43c9069-bb5f-11e5-8d81-f5e4d894ddb1,0x662,0x24bff9c0) label: (null) type: freebsd-ufs index: 2 So it is a GPT-partitioned disk, and at least one of the partitions is an “old-fashioned” UFS partition. That’s FreeBSD before ZFS became the de-facto standard filesystem (maybe just for me). This disk is simple to deal with (further notes below)! After I’m done with the disk, I power it down first with camcontrol standby ada3. I can hear the disk stop spinning and then pull out the connectors (power first, then data). And move on to the next disk. After disconnecting, dmesg confirms that I unplugged the correct drive: ada3 at ahcich0 bus 0 scbus0 target 0 lun 0 ada3: <WDC WD3200AAKS-00SBA0 12.01B01> s/n WD-WMAPZ0561055 detached (ada3:ahcich0:0:0:0): Periph destroyed This way I can step through all of the drives in my pile and then jot down what disk does what (or, in rare cases, decide they can be zeroed out and re-used for something else). Dealing with non-GPT disks The scheme reported by geom part list is GPT if you’re sensible, but of course it is possible to bump into MBR and BSD disklabels as well. The geom subsystem abstracts all that away, and the only realy difference is the names of devices. Scheme BSD, also known as BSD disklabel, gives you ada3a and ada3d, rather than numbered partitions. It is possible to apply this to a whole disk. It is also possible to have a BSD disklabel inside an MBR partition, but that’s a late-90s kind of setup. Scheme MBR gives you numbered partitions, but FreeBSD calls these slices instead of partitions and so you end up with ada3s1 instead of ada3p1. Dealing with UFS UFS partitions are pretty simple: mount them somewhere and things will be OK. I go for read-only, and I have a /mnt/tmp for all my arbitrary-disk-mounting activity. So mount -o ro /dev/ada3p2 /mnt/tmp it is (ada3p2 is the partition name found earlier). This particular disk turned out to be my main workstation drive around 2017, with a handful of still-interesting files on it. Ones I would not have missed if I hadn’t looked, but it was nice to find a presentation PDF I gave to SIDN once-upon-a-time. After looking, umount /mnt/tmp to unmount and release the disk. After that, power-down and disconnect as described above. Dealing with ZFS Slightly newer disks might be ZFS. Here’s the partition information for one: Providers: 1. Name: ada3p1 Mediasize: 250059309056 (233G) label: backup0 type: freebsd-zfs index: 1 It’s a GPT partition with a label, and ZFS on it. That means it’s part of a ZFS pool, and is probably referred to within the pool by its label. Possibly by its ID. In any case, ZFS needs to be imported, not mounted, because the filesystems are contained as part of the storage pool. The command to discover what is available is zpool import , which doesn’t actually import anything. pool: zbackup config: zbackup ONLINE gpt/backup0 ONLINE That’s encouraging: the pool consists of a single drive and everything is online. To make the filesystems in this pool available, I need to import it. I’ll force it (-f, because it was probably untimely ripp’d from whatever machine it was in previously), without mounting any of the filesystems in it (-N), readonly (-o readonly=on) with a temporary name (-t zwhat), like so: zpool import -f -N -o readonly=on -t zbackup zwhat After importing the pool, zfs list tells me what filesystems are available: zwhat 36.2G 189G 25K /zwhat zwhat/home 36.2G 189G 36.0G /tmp/foo/ I can mount a single ZFS filesystem just like a UFS filesystem. The ZFS filesystem knows where it would want to be mounted (/tmp/foo, I have no idea what I was doing back then), but we can treat it like a legacy filesystem: mount -t zfs zwhat/home /mnt/tmp After looking, umount /mnt/tmp to unmount and release the disk. After that, power-down and disconnect as described above. Dealing with Linux ext4 If the disk comes from a Linux machine, then it may have an ext4 filesystem on it. I still usually pick that when installing Linuxes. Here’s the partition information for one: scheme: MBR Providers: 2. Name: ada3s2 Mediasize: 64428703744 (60G) rawtype: 131 type: linux-data There is ext4 support in the FreeBSD kernel, although it is named ext2 (and some ext4 filesystems use unsupported features, and then it won’t mount). But for simple cases: mount -o ro -t ext2fs /dev/ada3s2 /mnt/tmp does the job. Dealing with linux-raid I found two disks, both WD Caviar Blue, labeled EBN D1 and EBN D2 with similar layouts. Those are linux-raid disks, and this is something I can’t deal with in FreeBSD. Heck, I’m not confident I can deal with them under Linux anymore, either. Providers: 1. Name: ada3s1 Mediasize: 493928031744 (460G) efimedia: HD(1,MBR,0xa8a8a8a8,0x3f,0x398033d3) rawtype: 253 type: linux-raid Re-purposing Disks KDE has a lovely partitioning tool, but I wouldn’t be me if I didn’t go for the command-line approach. Make sure the disk isn’t mounted anywhere, but is powered up. Zero out the first gigabyte or so of the disk: dd if=/dev/zero of=/dev/ada3 bs=1M count=1024 I guess this isn’t strictly necessary, and geom warns during this operation that the GPT is corrupt and the backup GPT (at the other end of the disk) should probably be used. Ignore that. Destroy the partition table some more: geom part destroy -F ada3 , now it is really dead. Make a new GPT partition table on the disk: geom part create -s gpt ada3 Start adding partitions to the partition table. I (now) use labels with the last digits of the drive’s serial-number. This drive gets a gigabyte of swap (just in case) and the rest is a ZFS partition which I can add to a pool later. geom part add -t freebsd-swap -s 1G -l swap-159666 ada3 geom part add -t freebsd-zfs -l zfs-159666 ada3 Why the labels-with-serial-numbers? Well, that’s so that I can subsequently create a ZFS pool from labeled partitions, and it remains obvious where the parts of the pool come from and also prevents name-collisions from naming everything backup0 and so.

- GSoC: differences of expectations between students and organizations (2026/01/28 00:00)I've been administering KDE's participation in the Google Summer of Code program for the last few years (and mentoring on some). This post is just some personal thoughts on the differences between what the KDE organization expects and what usually the applicants want (I'm not in everybody heads, it's assumptions from my experience). I don't provide any solution (because I don't have any) and there is no judgment (both point of views are valid), just a personal point of view. Applicants point of view GSoC is a individual competitive program which can be a huge boost to start a career. There are usually two major reasons for the applicants to participate in GSoC: the money. the experience and the line in the CV for real life work. There is, for a lot of applicants, no genuine interest in the projects (at least at the beginning, the first interaction is often "I want to start contributing to KDE and prepare for GSoC"), and they mostly want a GSoC slot. Small digression, on one of my projects, two people already asked to contribute and if we were doing GSoC, but after telling them that contributions are welcomed and we will only propose a topic if we feel enough confidence that the contributor would stay after, they told us they preferred to choose another project. Contributors consider GSoC as an end of their studies, not a project they want to contribute after: there is also a change of life to consider between university life and work life and a balance to achieve when starting the latter (which could be in a different town/country) which may be a reason for the drop of interest. Organization point of view GSoC is an opportunity to welcome new contributors to our community. The organization usually expects from GSoC: contributors willing to contribute regularly to their projects. implementation (partial or total) of the proposed ideas. having a positive return on investment (is the time spent mentoring worth the result?) GSoC is mostly a step to have contributors learning about the projects, and contribute in the long-term. Long-term is purposely vague; what we expected for the GCompris project was the contributor would contribute at least one year and mentor for the next GSoC (so a loop was present, and applicants would also gain an experience on mentoring, while giving some relief to the other experienced mentors) but it can vary depending on the project. For the return on investment, mentors do not consider it good having spent more than three months mentoring for projects they could have done in less time they spent to mentor the contributor. Helping someone grow is always personally rewarding but we still hope this person will also show us the results of the teaching by improving our projects in the future. Impacts of the differences There is a huge difference on the expectations. What can we do to reach a common ground where everyone is happy? Organizations cannot force anyone to contribute after the GSoC end. If money is the main motivation to stay, most organizations will not have money to hire applicants to work after (and do we want to hire someone only motivated by money? No, it's not OSS values, we love passion). Find ways to create a real interest for the organization. In KDE, we have the chance to have tons of projects with different topics (astronomy, education, digital painting, video editing, scientific plotting, games, desktop environment, system administration, internationalization, ...) where it is easy to participate to other projects from time to time and learn new things if we are curious enough. Be stricter on the entry point for organizations: explicitly say in the beginning that we expect a long-term relationship not just the equivalent of an internship. It should reduce the number of applicants and only keep the ones with a genuine interest (if applicants are honest of course). Organizations/Mentors could reduce their objectives of GSoC and consider that contributors are here to produce and spend less time on training/mentoring, expecting contributors already know the basics, but this would totally spoil the nature of the program. Another track is to find the projects where contributors stay / don't stay and understand the difference. Most of the big KDE applications don't manage to keep their contributors, while smaller ones do. Maybe as a contributor, it's because it's more difficult to take decisions, feel included/listened on large projects because they have a high maturity level/long-term contributors and a well-defined vision? Whereas on smaller projects, there are fewer constraints from the existing environment and it feels more rewarding and motivating to contribute there? To conclude, here are the statistics for KDE retention the last years: Year Started Completed Active after 1 year Active after 2 years Active after 3 years 2018 20 17 5 5 4 2019 24 22 9 8 8 2020 21 19 2 2 1 2021 16 15 8 6 3 2022 7 6 5 1 0 2023 9 7 3 3 2 2024 10 10 4 2 - 2025 15 12 6 - - That is, an average of 15 people sign up each year, of which an average of 90% finish 44% continued contributing 1 year later 28% continued contributing 2 years later 22% continued contributing 3 years later We would of course love having more contributors staying at least one year but it's almost half and a quarter that stay active for a few years!

- In praise of memory-leak-detection (2026/01/23 23:00)Nicolas Fella wrote a bit about enabling memory leak detection in KDE CI, and I thought I’d add some comments from a different software engineering environment (e.g. my work-work). Guidelines for Memory Management At work-work, we have a slightly peculiar software environment: Bleeding edge C++ use – C++23 if possible, 26 features being experimented-with – and a strong reliance on C++ language and library features. Use C++ containers, std::string (with an *implicit “here be UTF-8-encoded strings”), std::jthread, business-logic in standard C++ wherever possible. Qt 5.6.3, from 2017, for UI code. That’s pre-C++17. This leads to two guidelines about memory-management in our application: Use Qt’s memory model and ownership only for QWidget’s inheritance tree, .. well, ok, incidentally for things inheriting from QObject. Use C++ resource management for all other memory-management. This does mean that depending on where in the codebase you’re working, you either have to be a “C++ purist” (as Nico puts it) or a “Qt pragmatist” (as I’ll phrase it). Note that the guideline is not “use smart pointers”, because that last guideline can deconstructed a little (it wouldn’t surprise me if this was inspired by Klaus Iglberger): If a class manages a resource, then that resource-management should be the only thing it does, If an object needs resources, then those resources should be members (sub-objects) of a class as above. Often that means that memory-management is in the hands of std::unique_ptr, but std::vector does the job also. We have a handful of other classes for resource-management as well, like a wrapper for FILE * for those places where we need to interact with C’s stdio library. Granted, FILE * is probably not a source of memory-leaks, but it is a managed resource, and forgetting one will lead to leaking file-descriptors in the long run. Leaky Libraries Dealing with memory leaks can be difficult particularly when they happen in libraries not under your control. As an example, I wrote this program ( headers elided for brevity) which is a Qt5 program: int main(int argc, char **argv) { QApplication a(argc, argv); QTimer::singleShot(5000, qApp, &QApplication::quit); return a.exec(); } This is, like, the simplest Qt5 program. It sits there for five seconds and then quits. It also leaks 1662 bytes of memory, in 19 allocations, according to my ASAN output. They leak from allocations done in libQt5Core. Adding a QLabel and displaying some text adds leaks in libfontconfig, and the leaks keep accumulating as more libraries enter the mix. Granted, none of these leaks are large. I’m not even sure that they are impolite, but they’re there and it makes tracking down leaks in my code harder, because there’s some baseline of leakage that I need to ignore. Filtering out the noise becomes a serious undertaking. Takeaway Chasing all the memory-leaks is hard. Chasing any leaks in KDE Frameworks is something I can only applaud.
- Detecting Memory Leaks in KDE CI (2026/01/23 21:00)Leaking memory is impolite. It’s messy, it can suggest logic bugs, and thanks to AI grifters RAM is expensive. Unfortunately C++ makes it rather easy to leak memory. Fortunately we have tools to find such leaks. One such tool is Leak Sanitizer (LSAN) from the Address Sanitizer (ASAN) family. It’s using compiler-based instrumentation for the code to reports any leaks after the program terminates. KDE’s CI infrastructed has ASAN enabled for a while. However the leak sanitizer part was explicitly disabled, so no leaks were reported as part of the CI build and test run. This is because a number of projects have pre-exisiting memory leaks that would cause the C build to fail. Of course those should be fixed eventually, but in order to do that we need to know where they are. Also, for projects that currently don’t have any leaks we want to enforce keeping it that way. A few lines of Python later KDE’s CI system now allows to enable LSAN on a per-project basis. The .kde-ci.yml file that governs CI builds in KDE gained a new option enable-lsan. It is off by default for now for compatibility, but we may consider enabling it by default eventually. If enabled and any memory leak in a test is detected, that test and therefore the whole CI pipeline will fail. Now once we found a leak, what can we do about it? There’s several options: Use good old delete/free(). Works, but is often rather error-prone. Use QObject’s parent mechanism. Works, but often frowned upon by C++ purists. Mostly makes sense for widget hierarchies. Smart pointers like std::unique_ptr/std::shared_ptr. These are great because they allow to express the ownership on an API level and make ownership transfers explicit. Often the best choice for business logic code. LSAN is now enabled for some Frameworks CI builds, but ideally it would be enabled for all KDE projects. And of course any leaks found along the way should be fixed. Happy leak-fixing!

- Season Of KDE 2026 Projects (2026/01/21 00:00)Every year the KDE Community actively helps people to become active community members and contributors to Free Software through our Season of KDE mentorship programs. We would like to warmly welcome this year's mentees Aviral Singh, Keshav Nanda, Vishesh Srivastava, Varun Sajith Dass, Aditya Sarna, Jaimukund Bhan, Navya Sai Sadu, Kumud Sagar, Arun Rawat, Tanish Kumar, Ajay Singh, Mohit Mishra, Rohith Vinod, Shivang K Raghuvanshi, Onat Ribar, Hrishikesh Gohain, Aryan Rai, Advaith SK, CJ Nguyen, Siddharth Chopra, Nitin Pandey, Pavan Kumar S G, Sayandeep Dutta, Sairam Bisoyi, and J Shiva Shankar. They will be working on 21 projects covering a wide range of apps, frameworks, utilities and software in general to improve KDE. Sok 2026 Projects Standardise translation reference paths across all KDE projects Translators work on PO files that contain the translation data, including the file path to the file that the specific translation comes from. To understand the purpose of a particular string, sometimes the translators need to view the translatable strings in the code itself. To allow KDE to build tooling around the paths, the PO files must be standardised so that all contain file path references relative to the project root rather than from an arbitrary directory. This work has been started already but will be finished during this SOK project. Aviral Singh and Keshav Nanda will work under the guidance of Finley Watson on edge cases, testing and cleaning up the merge requests ready for merging. They will also improve the test script. Lokalize tasks All Lokalize projects will be mentored by Finley Watson. Introduce Appium testing Vishesh Srivastava will be integrating Appium testing in Lokalize. Appium is already used by other KDE software, and could be very helpful for testing UI changes, including keyboard shortcuts. This task will include coordinating with other mentees as they modify parts of the UI, as well as writing other general tests. Improving logic consistency and MacOS platform stability Varun Sajith Dass will work on fixing reported bugs, and improving string processing in many parts of Lokalize. Varun's aim is to increase the robustness of Lokalize's existing features, improve the quality of the output, and make following the Human Interface Guidelines easier for translators. This work will require coordination with other mentees e.g. for writing tests. Varun also aims to make it possible to build Lokalize on MacOS by fixing bugs related to this. Fix the glossary The glossary tab in Lokalize is unintuitive and hard to use, and currently crashes Lokalize unless you manually add the file that saves the glossary data to disk. Aditya Sarna and Jaimukund Bhan will update the UI so that it is easier to use, improve the glossary's behaviour, fix bugs and better follow the Human Interface Guidelines. They will work with the translators and visual designers to ensure their work follow KDE best practices and creates meaningful improvements. Jump to next translation unit when sort filters are applied The editor tab contains a dock widget called "Translation Units" which has the ability to filter and sort entries in translation files with the search bar. Moving between entries while approving them by using the shortcut jumps about in the list, rather than working down the sorted list correctly, one after another. Navya Sai Sadu and Kumud Sagar will be working together to fix this so the keyboard shortcut behaves as expected. Redesign translation memory tab The translation memory tab allows you to pick a TM (saved translation pairs from previous translation jobs / files) to search through, and shows the results in the list below. Arun Rawat will be redesigning the UI to enable searching multiple memories at once, with these settings saved per-project. Additionally, the Translation memories manager will be merged into the tab instead of existing separately e.g. by moving TM-specific entries into the right-click menu, and adding more general buttons into the TM tab page, or the toolbar that is specific to the TM tab. Standardise menubar Lokalize uses a KDE framework, KXMLGUI, to manage its menubar and status bar. In Lokalize, KXMLGUI allows you to define the contents of the menubar for each tab. Right now the tabs have different ordering of menus with some menus missing in certain tabs. Tanish Kumar will re-design the menubar so all tabs to offer the same menubar. Where a tab does not use a menu, the menu will be added, with menu options disabled. All Lokalize projects will be mentored by Finley Watson. Investigate alternatives to dblatex to convert docbook to pdf KDE’s documentation build pipeline currently relies on a legacy, copy-pasted fork of dblatex embedded inside the docs-kde-org repository. While functional, this setup obscures Git history, complicates upgrades, and makes KDE-specific customizations such as kdestyle difficult to understand and maintain. Ajay Singh, under Johnny Jazeix guidance, will investigate the possibility of using other tools than dblatex (such as pandoc) to create the pdf from docbook. The aim is to see if it fixes the current issues we have with non-supported non-ascii languages. And if there is a working alternative, he will work on trying to have a similar style to what we currently have in the kdestyle. Extract dblatex fork from docs-kde-org repo and improve non ascii languages support we are currently reworking the documentation website. The first task was to generate the documentation of each repo in a specific job. Mohit Mishra will work on extracting the dblatex from the code into its own repo (keeping the history) and finding out if we can directly clone the original repository instead of having a fork. Mentored by Johnny Jazeix, the overall goal is to try to use the upstream dblatex (shipped in distributions) to generate the pdf, experiment with XeTeX PDF generation engine instead of pdfTeX to create PDF for non supported non-ascii languages (Arabic, Chinese, Japanese, Korean...). If we can't improve it, extract dblatex fork on a specific repo to ease the maintenance` Implement font subsetting when saving files in Okular Okular supports PDF annotations and form-filling. When a user adds text to a document, Okular must ensure that the text remains readable on any system irrespective of whether the font is installed locally or not. Hence the font data is directly embedded into the document using the PDF rendering library Poppler. The problem arises due to the lack of proper font subsetting (as Poppler does not support this). Modern OpenType and TrueType fonts contain thousands of glyphs for various languages and symbols. Okular approaches this by embedding the entire font file into the document. This causes an undesirably large file size due to all the extra unused glyphs/symbols being embedded. Rohith Vinod and Shivang K. Raghuvanshi, under Albert Astals' supervision, will work on solving this problem using the hb-subset-input-glyph-set API. Plasma Setup: mobile support Plasma Setup is KDE's first run setup wizard, providing a friendly way to create the first user account and configure basic system settings. Unfortunately it only works on desktop form factors Under Kristen McWilliam's guidance,Onat Ribar will work on supporting Plasma Setup for Plasma Mobile as well. KEcoLab Recent updates in the lab mean that X11-based emulation tools like xdotool are obsolete. Guided by Joseph P. De Veaugh-Geiss, Karanjot Singh, and Aakarsh MJ, Hrishikesh Gohain will be tasked with porting existing scripts to a Wayland-based tool. Once Wayland support is ready, Hrishikesh will prepare test scripts to measure the KDE Plasma Desktop Environment itself. Turning mentorship.kde.org into a proper onboarding platform mentorship.kde.org currently looks like a website, but does not behave like an onboarding system. Aryan Rai and Advaith SK will be required to convert the site into a guided entry point for KDE mentorship. Anish Tak and Paul Brown will be guiding Aryan and Advaith throughout the project. Automate Promo data collection Promo collects data from different sources that measure how our followship grows, how many outlets are talking about us, what is our level engagement, etc. This information is currently collected by hand and is a massive time drain. CJ Nguyen, mentored by Paul Brown, will create systems to automate the collection, storage and analysis of this data. Markdown and plain text editors for Marknote Siddharth Chopra will be adding two editors to MarkNote, an app that lets you create rich text notes and easily organise them into notebooks. The first editor is a raw markdown editor for .md files and a plain text editor for .txt files. Siddharth also plans to work on making some improvements to the current markdown editor. Carl Schwan will be Siddharth's mentor in this project. Making Cantor’s existing tests visible, reproducible, and actionable in CI In this project, Avyakt Jain aims to activate Cantor’s existing testing infrastructure in a low-risk, incremental, maintainer-friendly way by (1) producing a clear, factual overview of current test coverage and gaps, (2) enabling a minimal, MR-scoped CI test job that provides visible JUnit-based feedback, and (3) improving reproducibility and documentation for running tests locally. The expected outcome is faster, more reliable feedback for maintainers and contributors, without enforcing new quality gates or changing Cantor’s runtime behavior. Alexander Semke and Stefan Gerlach will be supervising Avyakt's work. Call log synchronization and backup in KDE Connect Nitin Pandey will be working on improving telephony integration in KDE Connect by implementing call log synchronization and backup from Android devices to the desktop. Instead of creating a separate desktop client for call history, the project will integrate call logs directly into the existing KDE Connect SMS client on the desktop, providing a unified communication view. Albert Vaca will be mentoring this project. Enhancement of KDE Mancala: Engine Parallelization and Digital Asset Creation Pavan Kumar S G will speed up MankalaEngine by enabling it to use threads, Pavan Kumar SG will also create artwork to be used in the Mankala NextGen GUI. This project will receive guidance from Benson Muite and Srisharan VS. Improve Mankala GUI and add translations for Game variants Sayandeep Dutta will improve the visual appeal of Mankala NextGen GUI and contribute towards it going through KDE Review. In addition, Tamil translations will be created for MankalaEngine and Mankala NextGen. Srisharan VS and Benson Muite will support this project. XMPP Support in Falkon through WebXDC Sairam Bisoyi will create a Falkon extension to allow it to be used for chat using the XMPP protocol and its WebXDC extension.. The project advisors are Schimon Jehudah, Juraj Oravec and Benson Muite. Adding Vamana Guntalu to Mankala Engine and a WebXDC bookmarking system in Falkon J Shiva Shankar will add the Vamana Guntalu mancala game to MankalaEngine. J Shiva Shankar will also create a Falkon extension to allow synchronization of website bookmarks across different devices using the XMPP protocol in a WebXDC application. The project advisors are Schimon Jehudah, Juraj Oravec and Benson Muite. Stay in the loop! You will be able to follow the progress of all mentees through their blog posts on KDE's planet, and by joining the relevant project communication channels.
