KDecoration2 – The road ahead

Filed under
KDE

Yesterday I blogged about why Breeze is not the default window decoration in KWin 5.0. The blog post touched a little bit the problems with our decoration API. In short: it’s QWidget based and that doesn’t fit our needs any more. It uses a QWidget as an X11 window. At the same time KWin intercepts the rendering and also input handling, redirects it and forwards it. So why use a QWidget at all? Also using a QWidget is quite a memory waste in the Qt5 world. The QWindow behind the QWidget uses a QXcbShmImage with the same size as the window. As explained in yesterdays blog post the window has the size of the managed window plus the decoration. So for a maximized window we hold an image of the size of the complete window while we just need the titlebar strip. We can do better Smile

  • SFLPhone-KDE 1.4.0 released!

    Savoir-faire Linux is proud to announce the immediate availability of SFLPhone 1.4.0. This release finally enables video by default. We have refactored the video implementation to be much more robust against a variety of conditions and made the configuration more flexible. It is also now possible to stream a variety of file types and even share your screen. Other interesting features include support for the JACK audio system used by audio industry professionals and hobbyists. Thanks to improvements in audio buffering, latency and resampling, audio quality is noticeably better. The KDE client now has much better Akonadi support. It can now act as a KAddressBook replacement for most phone related scenarios. There will probably be one final KDE4 release before officially making the switch to KF5. The SFLPhone-KDE logic backend, libqtsflphone, has been compatible with Qt5 for over a year, some of the UI dialogs have yet to be ported. As for SFLPhone in general, we plan to merge work that has been done in parallel for a while now to make the daemon more modular, easier to build, more secure and more portable to other operating systems.

  • Plasma Active on QT5/KF5

    Hello, this is my fourth report for my GSoC. This week I have ported the Panel for Plasma Active. The UI of the Active Panel has not changed much. As you can notice some of the Plasmoids are missing because they have not been ported yet (like the Homescreen Plasmoid), but there is no missing functionality from the Panel. Also the notification icons are invisible while they are inactive, as this is the expected behavior.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
