Okular’s editable forms are no longer mis-rendered when inertially scrolling (Kezi Olio, Okular 1.11.2)

When your scanner can almost but not quite fit a particular page size, Skanlite will now display the option to scan to that page size anyway (e.g. 215mm wide scan beds now give you the option to scan using the US Letter page size) (Kåre Särs, libksane 20.12)

The text of Elisa’s keyboard shortcuts are now translated properly (Nikunj Goyal, Elisa 20.12)

Clearing the clipboard history on Wayland no longer crashes Plasma (David Edmundson, Plasma 5.20)

Improved the Plasma SVG cache heuristics such that various things which might sometimes be invisible after upgrading Plasma now show up like they’re supposed to (Arjen Hiemstra, Plasma 5.20)

On Wayland, clicking on a Task Manager entry while that entry’s tooltip is visible no longer crashes Plasma (Vlad Zahorodnii, Plasma 5.20)

On Wayland, clicking on a Task Manager thumbnail now activates that window, as you would expect (Marco Martin, Plasma 5.20)

KDDockWidgets 1.0 has been released

Filed under
KDE

KDDockWidgets is an advanced docking system for Qt, with features that are not available in QDockWidget. See our first blog post, for a quick introduction and the motivation for a new docking framework.

We’ve come a long way since the initial announcement of KDDockWidgets. The 1.0 release represents the culmination of one year of using the library in production for five different huge projects — one year of incorporating real feedback in the form of new features, bug fixes, or simply making the framework more customizable.

Plasma adventures - 5.19.4 tried and tested

Filed under
KDE

I like the momentum in the Plasma space. The last three years have been phenomenal, and there does not seem to be any fatigue, which typically affects most software projects after a while. Given that Plasma has been chugging on for a looong time now, this is rather impressive. What worries me, though, is that each new version brings in more fragility, more bugs. And this brings me back to the fundamental issue with the Linux desktop. It's simply not robust enough to be a day-to-day system for most people.

My mind simply cannot reconcile with breakages and compatibility issues. They feel like the easy way out of difficult situations with legacy models and usage patterns. Instead of creating a smooth transition to whatever the new thing is, what most projects seem to be doing is - break stuff. Why should plasma 5.19 be any less stable than say 5.18 or 5.15 or whatever. All in all, there's decent progress in Plasma, most notably the visuals and the responsiveness of the desktop, but these seem to come at the cost of good ole stability. Hopefully, future versions of Plasma will be able to give us both. That said, despite my grumbling, if you're after a solid desktop, Plasma is still the indubitable winner. Version 5.20 test coming soon!

KTextEditor - Small Things Matter

Software

Thanks to the feedback & patches provided by others, I found a bit more motivation to take a look at the small things that seems to be odd in KTextEditor.

Interesting enough, if you once notice a small detail (like a dead pixel on your display you suddenly find after years of use), it really sticks out like a sore thumb…

Here two small things that caught my interest this week.

First beta out for Krita 4.4

Filed under
KDE

The summer has come and gone since the 4.3 release, but we have not been sitting still. We had four Summer of Code Students this year, each of which completed their project. One of these projects has already made it into 4.4: The SeExpr fill layers! And that’s not the only new fill layer type… And fill layers now have on-canvas preview when you created them. And there’s a new plugin that helps when using Krita together with Godot. And there are new options for the brush engines and, of course, a ton of bugfixes! The full release notes bring you all the details!

So, today, we’re releasing Krita 4.4.0 beta 1: in two weeks we will release the final version. Please help improve Krita by testing this beta!

Plasma Beta Review Day

Filed under
KDE

Plasma 5.20 is now in beta, which gives us one month of intense testing, bugfixing and polishing.

During this time we need as many hands on deck as possible to help with finding regressions, triaging incoming reports and generally being on top of as much as possible.

In order to make this process more accessible, more systematic and hopefully more fun we are going to run an official "Plasma Beta Review Day"

Running PlasmaShell with Vulkan

Filed under
Graphics/Benchmarks
KDE

QtQuick, in slightly more words, is a scene graph implementation. At a developer level we create abstract "Items" which might be some text or a rectangle etc or a picture. This in turn gets transformed into a tree of nodes with geometry, "materials" and transforms. In turn this gets translated into a big long stream of OpenGL instructions which we send to the graphic card.

Qt6 will see this officially change to sit on top of the "Render Hardware Interface" stack, that instead of always producing OpenGL, will support Vulkan, Metal and Direct3D natively. The super clever part about it is that custom shaders (low level fast drawing) are also abstracted; meaning we will write some GLSL and generate the relevant shader for each API without having to duplicate the work.

    There are a set of characters the Bash shell treats in two different ways. When you type them at the shell, they act as instructions or commands and tell the shell to perform a certain function. Think of them as single-character commands. If you want to master the Bash shell on Linux, macOS, or another UNIX-like system, special characters (like ~, *, |, and >) are critical. We’ll help you unravel these cryptic Linux command sequences and become a hero of hieroglyphics.

  • Use Docker and Alpine Linux to build lightweight containers

    When it comes to Docker, sometimes less is more -- a maxim that applies especially to the base OS images installed in each Docker image. The use of a lightweight image -- one with less than 200 MB -- can result in significant resource and cost savings when used alongside optimized applications. A lightweight image also takes less time to deploy compared to a larger one, as it boots up faster. Most OS images are lightweight, with minimal compute resource requirements. But others, such as Windows containers, are huge. Alpine Linux is a super lightweight Linux distribution that's useful for Docker containers. In this Docker and Alpine Linux tutorial, we'll build an Nginx web server that demonstrates how small a Docker container image can be.

  • Improve your database knowledge with this MariaDB and MySQL cheat sheet | Opensource.com

    When you're writing an application or configuring one for a server, eventually, you will need to store persistent information. Sometimes, a configuration file, such as an INI or YAML file will do. Other times, a custom file format designed in XML or JSON or similar is better. But sometimes you need something that can validate input, search through information quickly, make connections between related data, and generally handle your users' work adeptly. That's what a database is designed to do, and MariaDB (a fork of MySQL by some of its original developers) is a great option. I use MariaDB in this article, but the information applies equally to MySQL.

10 Best Free and Open Source Linux Revision Control Tools

Version control systems play an essential role for developers. First up, they allow developers to safely store successive versions of source code. Besides providing a secure backup of the source code, this type of software lets developers revert back to a stable release if subsequent code changes have unforeseen consequences. Equally important, revision control tools enable team members to work simultaneously on a project’s code. If you have ever collaborated with other people on a project, you will appreciate the frustration caused by swapping files. Revision control is an excellent way to combat the problem of sharing files between developers without treading on each other’s toes. For open source projects having tens/hundreds of people working on the same code base, revision control software is essential. Read more
