Contributing to KDE is easier than you think — Localization plain and simple

Filed under
KDE
OSS

Today’s post will essentially describe how quick and easy it is to work with localization for KDE software. My latest post might have sounded intimidating or people might have gotten tired from reading it in the middle, which is a shame; hence the reason for this post.

Oh, existing translators should also have a reason to read this post, as I’ll be showing brand new functionality in Lokalize too.

As a brief note, I’m currently using openSUSE Krypton with Plasma from master, meaning it’s as updated as possible. I’m also using the XWayland session, because it’s dope af. It doesn’t affect my workflow at all, either.

But well, let’s keep it short and begin.

  • This week in KDE

    At this point we’ve got nearly all of the significant regressions from Plasma 5.18 fixed (so go file bugs if you have any new ones) and we’re starting to re-focus on fixing longstanding issues and land work for Plasma 5.19. Hopefully you’ll find something in this week’s update to feel excited about!

  • KDE Saw Many Bug Fixes This Week From KWin Crashes To Plasma Wayland Improvements

    This week in particular saw a lot of fixes in the KDE space for a wide variety of bugs.

    Some of the fixing that went on over the past week in the KDE desktop space included:

    - Fixes to the System Settings Online Accounts page.

    - Plasma is receiving a fix where a maliciously-crafted network name could cause remote images to be displayed.

    - Fixes for two common crashes in KWin.

Plasma Browser Integration Itinerary Integration

Filed under
KDE

Supported workflows for example include visiting a restaurant website where dropping them a call to ask for a table should be no more than two clicks away, or when surfing a trade show website, adding the dates to your calendar should be straightforward. If you want to read more about how the data gathering and processing in the background works, check out my previous blog post on the subject.

If you want to give it a try, install a recent kitinerary library (something along the lines of libkpimitinerary5), check out the itinerary branch of the plasma-browser-integration repository and follow the “How to install” instructions from source code on its wiki page. Once up and running, visit your favorite event, restaurant, and hotel sites and see if they have any structured data we can process! If you click “Inspect Element” in the popup’s context menu, the developer console will have some basic debugging information on the extractor.

Kdenlive: From Beginner to Advanced Video Editing

Filed under
KDE
HowTos

This is a different kind of video because it has a bit of Time Travel in it. In June 2019, I presented a talk at the SouthEast LinuxFest entitled “Kdenlive: From Beginner to Advanced Video Editing”. This was an interesting experience and the editing process took an excessive amount of time which I suppose is fitting for a video about video editing. In this video, you will learn some tips and tricks that I use for working in Kdenlive as well as some cool transitions like Matte Transitions. There was also a very useful Questions & Answers section at the end of the talk.

I actually learned some more things during the process of editing this video so there is always plenty to learn about this kind of software. If you would like more Kdenlive videos from me then please leave a comment below. I would be happy to make some specific tutorial videos, this is more of an overview and I think there’s plenty to show in tutorial form.

GNOME and KDE: GNOME Shell and Mutter, Qt, Plasma Mobile and Okular for Debian

Software
GNOME
  • GNOME Shell + Mutter See Changes For Tracking Software Rendering, VNC To Toggle Animations

    GNOME Shell and Mutter saw a set of patches land today for GNOME 3.36 that have been around for a few months and deal with the tracking of software rendering and VNC usage where GNOME Shell should in turn disable animations to ease the rendering workload.

    The GNOME Settings Daemon has until now been responsible for controlling the animation heuristics when they should be disabled while now Mutter has added support for tracking software rendering situations and in turn GNOME Shell is relying upon that for determining when to disable desktop animations.

  • How not to lose the alpha channel

    Working on color imagery for QiTissue recently, I realized we were accidentally losing the alpha channel in multiple places. For efficiency reasons, we keep colors in memory using the QRgb type, and convert that to/from QString for serialization purposes via QColor as needed. Here’s what I discovered about why that doesn’t work, and some ways I fixed it.

    Firstly, be aware there is no QRgba in the Qt API . There is only QRgb, for 8bit color channels. It can hold an alpha value too, despite the lack of a trailing a in the type name. Then there is QRgba64 which uses 16bit per color channel. For our purposes, 8bit per channel is sufficient. So where do we lose the alpha channel, when QRgb can store it in principle?

  • Fosdem and Plasma Mobile Sprint

    From January 31st to February 8th I went on a little tour, first at the two days of Fosdem in Brussels, then to Berlin for a KDE sprint about Plasma Mobile.

    It was the first time i went to Fodem: it’s an awesome experience, even tough big and messy: which is the awesome of it… and the bad of it at the same time

    Even tough there were 800 talks I didn’t attend that many, some about the Elixir language, some about retrocomputing, some about iot stuff. At Fosdem the best thing to do there.. is meeting a lot of interesting people, rather than attending talks, which are very interesting never the less, which you can find videos here.

  • Norbert Preining: Okular update for Debian

    The quest for a good tabbed pdf viewer lead me okular. While Gnome3 has gone they way of “keep it stupid keep it simple” to appeal to less versed users, KDE has gone the opposite direction and provides lots of bells and knobs to configure their application. Not surprisingly, I am tending more and more to KDE apps away from the redux stuff of Gnome apps.

KDE’s Plasma Mobile Is Shaping Up Nicely on the PinePhone

Filed under
KDE

Last month, we took a closer look at how UBports’ Ubuntu Touch mobile OS progressed on the PinePhone, thanks to a video shared by developer Marius Gripsgård. Now, we have a sneak peek at another great system for the PinePhone, KDE’s Plasma Mobile.

Unlike Ubuntu Touch, which is a full-fledged mobile operating system, Plasma Mobile is actually a user interface (UI) for mobile devices running on top of a GNU/Linux distribution, such as KDE neon or the Alpine Linux-based postmarketOS.

  • Season of KDE Final Report

    SoK ended finally on 17th February 2020. I am happy to share that I have completed the project "Add multiple datasets to several activities" and passed the final evaluation!!!
    As I have written a post a few days back to update about my work which you can find over here.

  • Will Stephenson: It is time for a war on tabs

    All this causes additional cognitive load/dissonance when using your computing device.

    I'm not saying Plasma needs to become a tabbed window manager, but we can do better, and it is definitely time to declare war on the mess above.

Best Open Source Slack Alternatives for Team Communication

You are here: Home / List / Best Open Source Slack Alternatives for Team Communication Best Open Source Slack Alternatives for Team Communication Last updated February 25, 2020 By Ankush Das Leave a Comment Brief: Here, we shall take a look at the best open source slack alternatives that you can choose to communicate with your team at work. Slack is one of the most popular team communication services for work. Some may call it a glorified IRC but that doesn’t impact its popularity. It is available for free with additional features offered in its paid plans. Though Slack can be installed on Linux thanks to an Electron app but it is not open source, neither the client nor the server. In this article, I’ll list a few open source Slack alternatives that you can try. Read more

Dual-Boot GNU/Linux and Android

  • Planet Computers' clamshell phone can dual-boot Android and Linux

    Planet Computers' laptop-like Cosmo Communicator phone just became that much more useful to its audience of very particular power users. The Cosmo now supports a promised multi-boot function, letting you run Android (both regular and rooted), Debian Linux and TWRP on the same device without one replacing the other. You'll have to partition your storage and know your way around a boot menu, but this will give you a way to run Linux apps or otherwise experiment with your phone. You won't lose over-the-air updates for Android by installing Linux, Planet Computers said. The multi-boot firmware is available for free, and there are instructions for installing Debian and other software. This still isn't for the faint-hearted. However, it also represents one of the few instances where a phone maker has officially enabled support for operating systems besides the one that ships with the device. The Cosmo is also fairly well-suited to Linux thanks to its keyboard -- you won't have to jump through hoops to use the command line.

  • How can IT manage Android Things devices in the enterprise?

    Recent versions of Google's Android OS support a wider range of devices via the Android Things program's APIs and managing some of the newer devices can seem complicated at first. Thankfully, the underlying OS is essentially the same on all Android devices, so the EMM platform management and enrollment processes are usually similar for Android Things devices. The challenge for mobile admins is to develop a version of Android -- using the Android SDK and Android Things APIs -- that functions on these dedicated devices.

Update on Linux support: creation of a CERN Linux community forum

For those, a CERN Linux community forum has been created. Users will be able to post issues that they encounter when using non-CERN-supported Linux distributions and to post solutions. Users are also encouraged to post articles with comments and ideas that could help make this forum more dynamic and useful to them. Various methods for printing and using AFS, SSH, ROOT and other tools at CERN can be found on the internet. The CERN Linux community forum aims to collect these methods, as well as new ones that may be created directly in it. Read more

Python Programming

  • Introduction to Python SQL Libraries

    All software applications interact with data, most commonly through a database management system (DBMS). Some programming languages come with modules that you can use to interact with a DBMS, while others require the use of third-party packages. In this tutorial, you’ll explore the different Python SQL libraries that you can use. You’ll develop a straightforward application to interact with SQLite, MySQL, and PostgreSQL databases.

  • Introduction to Image Processing in Python with OpenCV

    In this tutorial, we are going to learn how we can perform image processing using the Python language. We are not going to restrict ourselves to a single library or framework; however, there is one that we will be using the most frequently, the Open CV library. We will start off by talking a little about image processing and then we will move on to see different applications/scenarios where image processing can come in handy. So, let's begin!

  • Talking to API's and goodlooking tools

    One of my go-to locations for security news had a thread recently about a tool called VTScan. I really liked the idea of not having to go through the browser overhead to check files against multiple scan engines. Although the tool (which is itself a basic vt-cli spinoff) already existed, I was looking for a new challenge, I decided to roll my own and add a few cool features! I'll have a thorough look at how python talks to API's with requests and I look at turning all this API data into a nice GUI application with click. I hope to give you some idea's for CLI styling in the future so I can see more awesome tools by you all!

  • From a rejected Pycon talk to a new project.

    Like many others, my talk proposal (early draft here) for Pycon US was rejected. So, I decided to spend some time putting everything in a new project instead. (Documentation here.) It is still a rough draft, but usable ... and since I've mentioned it in a few other places, I thought I should mention it here as well.
