Tutorial – Plasma

Filed under

While many user interface designers advocate simplicity and simplified decision-making for users (which often results in no decision-making at all), the KDE community [1] has stubbornly gone the other way, jam-packing all manner of features and doodads into its Plasma [2] desktop (see the "KDE Is Not a Desktop" box).

That said, if you want simple, Plasma can do simple, too. You can ignore all the bell and whistles and just get on with your life. But where is the fun in that?

  • LSFMM 2019 gains a BPF track

    The call for proposals for the 2019 Linux Storage, Filesystem, and Memory-Management Summit has been updated with an important addition: this year's event (April 30 to May 2, San Juan, Puerto Rico) will include a BPF track. The submission deadline has been extended to February 22 to allow BPF developers to put together their proposals.

  • KDE at FOSDEM 2019

    February means FOSDEM, the largest gathering of free software developers in the continent. I drove for two days down the winding roads and even onto a train and out again to take the bits needed to run the stall there. Fortunately my canoeing friend Poppy was there for car karaoke and top Plasma dev David got picked up along the way to give us emotional support watching Black Mirror Bandersnatch with its multiple endings.

    The beer flowed freely at Delerium but disaster(!) the venue for Saturday did not exist! So I did some hasty scouting to find a new one before returning for more beer.

    Rather than place us next to Gnome the organisers put us next to our bestie friends Nextcloud which was nice and after some setup the people came and kept on coming. Saturday was non stop on the stall but fortunately we had a good number of volunteers to talk to our fans and future fans.

  • Privacy-preserving monitoring of an anonymity network (FOSDEM 2019)

    Producing this transcript was more work than I had anticipated it would be, and I’ve done this in my free time, so if you find it useful then please do let me know otherwise I probably won’t be doing this again.

Slimbook & Kubuntu - Combat Report 5

Filed under

Anyway, I am still quite happy with Slimbook + Kubuntu. There are some annoying things - the Wireless connection glitch on first login, the icons in the task manager, the session save bug. But then, the system is stable, fast, ever so slightly but consistently improving, the game repertoire is pleasantly nice and growing, and overall, the desktop feel rich, fun and polished. You notice how advanced Plasma is when you switch over to other systems and try other environments. Me liking, but I wants even more good stuff! Well, to be continued some more.

This week in Usability & Productivity, part 56

Filed under

Here are the results of week 56 of KDE’s Usability & Productivity initiative. We’ve been working on Plasma 5.16 features and fixing old bugs in Plasma 5.12 and beyond.

One additional thing I’d like to mention is that we’re aware that many users of Discover in Plasma 5.14 are suffering from an inability to either check for updates or update their systems. This issue is fixed in Plasma 5.15 and beyond, but we’re working on a fix for Plasma 5.14 users that can be backported. Sorry for the breakage, everyone!

Anyway, onto the good stuff…

  • Qt 5.12.1 Released

    I am pleased to announce that Qt 5.12.1 is released today. The first patch release in the Qt 5.12 LTS series provides a large number of bug fixes and other improvements.

    Compared to Qt 5.12.0, the new Qt 5.12.1 contains nearly 300 bug fixes. For details of the most important changes, please check the Change files of Qt 5.12.1.

  • Qt 5.12.1 LTS Released With Around 300 Bug Fixes

    Qt 5.12 was released in early December as the latest Long-Term Support release for the Qt5 tool-kit. Out today is the first point release that contains hundreds of fixes.

    Qt 5.12.1 LTS has nearly three-hundred bug fixes. The fixes in this point release range from animated GIFs not rendering correctly to Wayland client flickering when running with NVIDIA graphics. But there are a ton of fixes all over the place with this first 5.12 LTS update. A complete list of the fixes can be found here.

  • Qt Design Studio 1.1 Beta Released - Now Includes Linux Packages

    Qt Design Studio, the solution for rapidly prototyping and developing complex user-interfaces with the Qt5 tool-kit while being a bridge between designers and developers, has reached its public beta release for the inbound Qt Design Studio 1.1.

    Qt Design Studio 1.1 Beta comes with blessed Linux packages after they were missed out on last year with the big 1.0 release. Qt Design Studio 1.1 also features improvements to its Photoshop Bridge (now supports merging), support for more JavaScript functions with the editing, various timeline fixes, documentation additions, and other improvements.

KDE and More: Welcoming People to KDE at FOSDEM 2019, KDE Bugsquad and Raspberry Pi Compute Module 3+

  • Come Home to KDE at FOSDEM 2019

    This year we are jam-packing it with interesting stuff. The first thing you'll see as you arrive is Krita's demo. Wolthera van Hövell, a talented artist that regularly contributes to Krita, will be painting live at the booth, demonstrating all the new features on a large screen for everybody to enjoy. Then on Sunday, Camille Moulin will be demonstrating how to edit video using Kdenlive.

  • KDE Bugsquad – Back in 2019! Ark/Kcalc/Spectacle Bug Day on February 12th, 2019

    I hope everyone has had an enjoyable holiday season! The KDE Bugsquad is back in 2019, almost 50 members strong! How awesome is that? We have 11 months left in 2019, and will be continuing our every-other-week schedule as last year, with one event on a Tuesday, one on Saturday, with one project per month. Hopefully that provides you some opportunities to fit it into your schedule.

    Our first project this year will actually be a variety pack of smaller projects, each with less bugs than the usual targets. I wanted to start out with some easier ones, while still targeting some important utilities most KDE users use. So, without further delay:

  • Raspberry Pi Compute Module 3+ offers more performance and better heat management


    Thanks to the use of Broadcom's 64-bit BCM2837B0 application processor and the use of 1GB of LPDDR2 RAM, the Raspberry Pi Computer Module 3+ delivers more performance but has better thermal control as well, with the microcomputer drawing heat away from the processor.

KMyMoney 5.0.3 released

Filed under

The KMyMoney development team is proud to present version 5.0.3 of its open source Personal Finance Manager.

Some problems have been reported by many of you and the development team worked hard to fix them in the meantime. The result of this effort is the new KMyMoney 5.0.3 release.

Despite even more testing we understand that some bugs may have slipped past our best efforts. If you find one of them, please forgive us, and be sure to report it, either to the mailing list or on

From here, we will continue to fix reported bugs, and working to add many requested additions and enhancements, as well as further improving performance.

Review: KaOS 2018.12

Filed under

KaOS is an independent desktop Linux distribution that features the latest version of the KDE desktop environment, the Calligra office suite, and other popular software applications that use the Qt toolkit. KaOS employs a rolling-release development model and is built exclusively for 64-bit computer systems.

Some changes have come to the KaOS distribution lately, including the migration of applications to OpenSSL 1.1 (from OpenSSL 1.0) and KDE Plasma 5.14 is now in the project's repositories. KaOS currently ships with a welcome window called Croeso which offers a lot of customization options for first-time users. Croeso replaces the old Kaptan welcome screen.

KaOS has dropped support for Qt 4 which has not received active development for a while. The latest snapshot also updates Calamares and introduces a fix to make sure systems with Btrfs volumes should install properly on UEFI-enabled computers. Further, the project's release notes warn the distribution cannot be installed on a RAID system.

The latest snapshot of KaOS is 1.9GB in size. Booting from this media brings up the KDE Plasma desktop. The interface features a blue and grey theme with the desktop panel displayed vertically down the right-hand side. I think KaOS may be the only distribution I have used which places the panel in this manner.

Once the live desktop loads we are shown a welcome window which offers to open the distribution's guide (which features installation instructions), launch the Calamares installer, display on-line documentation, show us the operating system's default passwords, or open the user forum. The forum and documentation links are opened in the Falkon browser.

KDE is adding Matrix to its instant messaging infrastructure

KDE has been looking for a better way of chatting and live-sharing information for several years now. IRC has been a good solution for a long time, but it has centralized servers KDE cannot control. It is also insecure and lacks features users have come to expect from more modern IM services. Other alternatives, such as Telegram, Slack and Discord, although feature-rich, are centralized and built around closed-source technologies and offer even less control than IRC. This flies in the face of KDE's principles that require we use and support technologies based on Free software. However, our search for a better solution has finally come to an end: as of today we are officially using Matrix for collaboration within KDE! Matrix is an open protocol and network for decentralised communication, backed by an open standard and open source reference implementations for servers, clients, client SDKs, bridges, bots and more. It provides all the features you’d expect from a modern chat system: infinite scrollback, file transfer, typing notifications, read receipts, presence, search, push notifications, stickers, VoIP calling and conferencing, etc. It even provides end-to-end encryption (based on Signal’s double ratchet algorithm) for when you want some privacy.

Canonical Is Planning Some Awesome New Content For The Snap Store

There I was, thoughtfully drafting an article titled "3 Things Canonical Can Do To Improve The Snap Ecosystem," when I jumped on the phone with Evan Dandrea, an Engineering Manager who just so happens to be responsible for the Snapcraft ecosystem at Canonical. As it turns out, that headline will need a slight edit. One less number. That's because I've just learned Canonical has some ambitious plans for the future of the Snap Store. Read more

Extensive Benchmarks Looking At AMD Znver1 GCC 9 Performance, EPYC Compiler Tuning

With the GCC 9 compiler due to be officially released as stable in the next month or two, we've been running benchmarks of this near-final state to the GNU Compiler Collection on a diverse range of processors.
