KDE Frameworks 5.73 Released with Many Changes to Breeze Icons, Kirigami and KNewStuff

Filed under
KDE

KDE Frameworks 5.73 is a monthly update to the open-source software suite, but it packs a lot of interesting changes. For example, the Kirigami UI builder received a new FlexColumn component and now supports action visibility in the GlobalDrawer, along with optimizations to the mobile layout and to the accessibility of the Kirigami input fields.

The Breeze icon theme saw a lot of changes too during the development cycle of KDE Frameworks 5.73, and it now comes with a bunch of new icons for Kontrast, kirigami-gallery, snap-angle, document-replace, SMART status, task-recurring, appointment-recurring, Overwrite action/button, and applications/pkcs12 mime type.

Kubuntu Linux 20.04 for a digital painting workstation: Reasons and Install guide.

Filed under
KDE
Ubuntu

Wooo, summer... Hot weather and a quick computer reinstall right in the middle of the production of the books because my previous Kubuntu 19.10 was obsolete and reached end of life in July. Bad surprise for me this time in the process: no way to install Scribus 1.4.8 stable anymore and all my books are done with that. The package was savagely forced replaced by 1.5.5~Development and no way to reinstall the previous version flagged as stable by the Scribus team.

So, I'll have to move the book project to this development version (it will take hours of adaptation because the text-engine changed between 1.4x and 1.5x). If you are on Windows, Mac, 18.04 or CentOS no worry for you: the package still exists there. Sad to see that no Appimage, Flatpack or Snap are around to rescue this issue... But let's close for now this parenthesis with a taste of bitterness. I'll cope with that, I saw uglier situations of upgrade in my life and this Kubuntu 20.04 is −about all other aspect− a splendid distribution so far.

The 10 Best KDE Plasma Widgets for KDE Desktop Environment

Filed under
KDE

If you were looking for the best KDE Plasma widgets for your Linux desktop, then you are in the right place. There is much debate about the fact of who implemented the widget feature first on a computer GUI. But nobody can deny that the widgets have brought a new era in the modern user interface. Most of the people rely on beautiful widgets for performing different tasks without opening the main instance of the program. Although Windows ditched their native desktop widgets feature with their Windows 8 for the sake of the live tiles. Linux still has a great library of widgets that are being maintained by the developer community.

KDE: How KDE is Made, Krita’s Scripting School and Plasma Browser Integration

KDE

  • The structure of KDE, or how anarchy sometimes works

    KDE is a funny beast. In a lot of ways, it’s an anarchic society that actually works!

    Engineers and designers work on KDE software and websites, but none of them are paid by KDE itself. Most are volunteers but some (myself included) are paid by 3rd-party companies. These people work on what they want or what they are sponsored by their company to work on, not what anyone in KDE tells them to work on.

    KDE has a board of directors, but they are elected by KDE’s membership rather than stockholders (there is no stock lol), and do not control KDE’s strategic direction the way the board of directors does in a corporation. Rather, they mostly take care of financial and legal matters, sort out copyright claims, help to organize the yearly Akademy conference, and so on.

    There is no formal “upper management” or even “middle management” layer. We have the “gardening team” whose members constitute volunteer managers, but we mostly do things like triaging bugs, following up on stuck merge requests, perform QA on unreleased software, and so on. We support the people doing the work, rather than telling them what to do.

  • Announcing Krita’s Scripting School!

    In 2018, we reintroducted scripting to Krita. Unlike our previous attempts to provide scripting, this time it took off! People are making all kinds of useful and fun extensions for Krita. Like a new color picker and mixer, a plugin to modify the way Krita’s subwindows are handled, new toolboxes, integration with other applications like Autodesk Shotgun,

    But what was missing was a good overview of the various areas that could be scripted. Tutorials and example code on how to use the scripting API in bite-size chunks. The regular API documentation is generated automatically from the APIDOX comments. It is a good reference but can be difficult to understand since it is generated from the C++ code that provides the scripting bindings.

  • Plasma Browser Integration 1.7.6

    I’m pleased to announce the immediate availability of Plasma Browser Integration version 1.7.6 on the Chrome Web Store as well as Firefox Add-Ons page. This release comes with a few bug fixes, performance improvements, and translation updates.

    [...]

    As usual, this release brings some improvements to media controls. Short sounds and videos are currently ignored to avoid trying to control e.g. a “new message” sound or short hover video previews. However, some live stream implementations don’t report the correct duration of Infinity but gradually fill up their time bucket every few seconds. Previously, the extension only checked duration once to determine whether to provide media controls. With this update duration is continuously checked and media controls would become available eventually.

    Furthermore, for websites that do not set album art through Media Session API, the video player’s poster is now used as album cover. This is the cover image that is often shown when the video isn’t playing.

    A new feature of QML Online is already available, allows it to run in any site/blog with minimal js/html code!

    Hopefully, our experience with QML examples, tutorials and documentation should change in the near future.

  • MyPaint Brush Engine [Final Phase]

    Coming to my project, it is almost complete apart from some finalisation related stuff that still is remaining. Perhaps, some review changes that my mentors shall give me once my current patch has been reviewed are also remaining.

    [...]

    I don't know why, but I always seem to have this feeling at the back of my head that something will come up that will be tough to handle and ruin my project. Though this has been happening even before GSoC started. That scares me a bit Sad Anyways.

  • Ubuntu's Prolific GNOME Developer Is Looking To Tackle Deep Color Support

    GNOME could soon be playing nicely with deep color displays that aim to offer more realistic color reproduction thanks to the greater bit depth for each color component. 

    Canonical's Daniel van Vugt who has led many of the Ubuntu GNOME performance optimization initiatives and countless bug fixes for GNOME since Ubuntu switched back to using it as the default desktop is now looking at plumbing deep color support. Daniel recently has been working on better graphics clock frequency scaling as part of optimizations to improve the GNOME 4K experience particularly when using Intel graphics. The latest area he started dabbling with is deep color support.

Latte Dock v0.10~ | July Update

Thanks to Martijn Vogelaar a new visibility mode for sidebars is supported. The new mode triggers Latte panel showing/hiding through the Latte Sidebar Button applet and global shortcuts but at the same time if the panel does not contain mouse for a period of time (can be set from Show timer) then it auto hides itself.

Visibility modes in general have updated their organization in order to be grouped much better. Currently they look like...

  • Python For Loop: Everything You Need to Know

    Loops are one of the essential elements in any programming language, and Python is not an exception to it. Loops are used to repeat a statement or a block of statements multiple times. If there were no concept of loops in programming languages, we have to write each statement again and again for the number of times we want to execute it. Python provides two types of loops to handle looping requirements, i.e., the while loop and the for loop. In this tutorial, we will learn everything about the for loop statement in Python. Before getting started with this tutorial, It is necessary to have Python installed and set up in your environment path. If you don’t have it installed already, refer to our step by step guide to install Python on Linux. The code presented in this tutorial can be run on the python shell, but it is recommended to run the code in a Python IDE. If you don’t have a python IDE installed in your system or want to know which IDE is a better choice to install, you can refer to our guide Top 10 best python IDE compared.

  • NihAV Is An Experimental Multimedia Framework Written In Rust

    NihAV is an experimental multimedia framework written in the Rust programming language. At the moment it's focused on diving into supporting decoders for different formats that lack open-source support right now / not yet reverse engineered, exploring new approaches for conventional multimedia concepts, and other experiments for advancing audio-video frameworks.

  • rra-c-util 8.3

    n this release of my utility library for my other packages, I finally decided to drop support for platforms without a working snprintf. This dates back to the early 2000s and a very early iteration of this package. At the time, there were still some older versions of UNIX without snprintf at all. More commonly, it was buggy. The most common problem was that it would return -1 if the buffer wasn't large enough rather than returning the necessary size of the buffer. Or, in some cases, it wouldn't support a buffer size of 0 and a NULL buffer to get the necessary size.

  • Embedded Programming and Beyond: An Interview with Warren Gay

    Interested in embedded programming? Warren Gay, an Ontario, Canada-based senior programmer, is an excellent resource for professional programmers, students, and makers alike. Here he talks about his new book, FreeRTOS for ESP32-Arduino (Elektor, 2020), and shares insights about FreeRTOS, ESP32, Arduino, embedded technologies, and more. You are sure to find his input informative and inspiring, especially if you plan to work with ESP32 or Arduino in the near future.

  • PHP 7.1 - 8 new features

  • Senior Developers don’t know Everything

    For about 20 years, I’ve been doing C++ and Qt and KDE development. I suppose that makes me a “senior software engineer”, also in the sense that I’ve hacked, programmed, futzed, designed, architected, tested, proved-correct, and cursed at a lot of software. But don’t let the label fool you: I look up just as much in the documentation as I ever did; senior developers don’t know everything.

  • Intel Cloud-Hypervisor 0.9 Brings io_uring Block Device Support For Faster Performance

    Intel's Cloud Hypervisor focused on being a Rustlang-based hypervisor focused for cloud workloads is closing in on the 1.0 milestone. With this week's release of Cloud-Hypervisor 0.9 there is one very exciting feature in particular but also a lot of other interesting changes. 

  • Joplin

    Joplin is a free, open source note taking and to-do application, which can handle a large number of notes organised into notebooks. The notes are searchable, can be copied, tagged and modified either from the applications directly or from your own text editor. The notes are in Markdown format. Notes exported from Evernote via .enex files can be imported into Joplin, including the formatted content (which is converted to Markdown), resources (images, attachments, etc.) and complete metadata (geolocation, updated time, created time, etc.). Plain Markdown files can also be imported. The notes can be synchronized with various cloud services including Nextcloud, Dropbox, OneDrive, WebDAV or the file system (for example with a network directory). When synchronizing the notes, notebooks, tags and other metadata are saved to plain text files which can be easily inspected, backed up and moved around.

  • An Early Look at Grounded

    You’re in control of a child, who looks like he/she hasn’t entered the teenager years just yet. Among four different children — two boys and two girls — they’ve got a big problem: they’ve been shrunk to the size of an insect. Join them in their adventure — either by yourself or with a group of online friends — as they fight to survive in someone’s backyard, trying to build shelters whilst defending against bugs, and figure out why they’ve shrunk in the first place. Enter Grounded, developed by Obsidian Entertainment — the studio that brought us such titles as Pillars of Eternity, The Outer Worlds, and Star Wars: KOTOR2.

Fedora: LTO, Nest and More

  • Fedora 33 Moving Closer To LTO-Optimizing Packages

    Going back to last year Fedora has been working to enable link-time optimizations by default for their packages. That goal wasn't achieved for Fedora 32 but for Fedora 33 this autumn they still have chances of marking that feature off their TODO list.  LTO'ing the Fedora package set can offer not only performance advantages but in some cases smaller binaries as well. This is all about applying the compiler optimizations at link-time on the binary as a whole for yielding often sizable performance benefits and other optimizations not otherwise possible. LTO is great as we often show in benchmarks, especially in the latest GCC and LLVM Clang compilers. 

  • Zamir SUN: Report for session 1 of FZUG @ Nest with Fedora

    Last month, Alick suggested the Fedora Zhongwen User Group (FZUG) can do a online meetup during Nest with Fedora. And based on the survey, people registered for two time slots, the first one is 9:00 PM Saturday evening UTC+8 which is not a good time for Alick, so I take up the coordinating role for this session. As for the tool, we decided to use Jitsi, as it should work fine for most of us and do not have any limitations. What’s more, it’s totally open source. During the meeting, I firstly introduced Nest with Fedora and it’s previous offline version, Flock to Fedora, to the attendees. It’s interesting to see that during the past years, we not only have new users in China, but also new contributors. One attendee shares that his motivation of being a packager is that deploying packages for their research in the lab is cumbersome before. So he decided to package all into Fedora and then he can just simply install them on every machine. It is good to know that people contribute back because they want to solve their own problems. Maybe this can be a talking point to attract more contributors in the future. After the self introduction, we continue by sharing our interesting stores with Linux. That is a lot of fun.

  • Jon Chiappetta: Last piece of relay software needed for my home bridged network

    If you are running a bridged/relayd network with macs on it you may need to also forward the multicast broadcasts (mDNS related) that allow the devices to automatically discover each other. On the WRT wifi client side, there is a pkg called avahi-daemon and you can configure to operate in “reflector” mode to forward these broadcasts across the specified interfaces. Running this service along with the dhcprb C program which takes care of layer 2 arp requests & dhcp gateway forwarding has been pretty smooth so far!

  • Russ Allbery: DocKnot 3.05

    I keep telling myself that the next release of DocKnot will be the one where I convert everything to YAML and then feel confident about uploading it to Debian, and then I keep finding one more thing to fix to release another package I'm working on. Anyway, this is the package I use to generate software documentation and, in the long run, will subsume my static web site generator and software release workflow. This release tweaks a heuristic for wrapping paragraphs in text documents, fixes the status badge for software with Debian packages to do what I had intended, and updates dependencies based on the advice of Perl::Critic::Freenode.
