  • Mariam Fahmy GSoC’21 Week 2, 3 and 4: Finalizing learn decimals activities

    In this activity, a decimal number is displayed. the bar with the arrow represents a full unit, and each square in it represents one tenth of this unit, the kid has to drag the arrow to select a part of the bar, and drop the selected part into the empty area so that the number of dropped bars corresponds to the displayed decimal number.

    For every dropped bar, all bars are organized after 1 second from the drop action such that the kid can see the reorganization of bars, as a result we add a place for a 6th bar to have at most 5 full bars.

    The activity provides instruction tutorials on how to play with it, both vertical and horizontal layout are supported.

  • KDE Documentation & New Job at Nextcloud

    It also means I’m leaving my current part-time job at the KDE e.V. working on the documentation tooling. This was shorter than initially planned (a bit more than one month instead of three), but even though I didn’t finish doing everything I wanted to do, I still did a few things during this short time.

    First, I continued my previous work on, making it possible for the translators to translate the content. For now, only the Kirigami tutorial is translated, but more should be available by simply toggling some switches.

    Another thing I worked on was phasing out This website was created before develop.k.o was created and develop.k.o is nowadays a better place to add the plasma mobile developer documentation, next to the Kirigami and Plasma tutorials. The small bits of user documentation is getting moved to the plasma-mobile website.

    And also made some small improvements to KApiDox. I fixed the sorting of products to always include the KDE Frameworks and KDE PIM on top made the navbar consistent with and a made a few other minor tweaks.

    Aside from that I also made many small patches to the API documentation itself in Ki ri ga mi, KGuiAddons, Plasma Workspace and a few other places.

    I will still be around and you can still ping me on Matrix for documentation tooling related questions Smile

    Thanks a lot to the KDE e.V. for entrusting me with this responsibility. If you want to help supports others and make KDE software better, consider donating to the KDE e.V.. The donation is tax-deductible in Germany (and maybe in other EU countries too).


  • Christian Hergert: GtkSourceView Searching with PCRE2

    Last year I did some work to make GtkSourceView use PCRE2 for syntax highlighting. The primary motivation there was to improve syntax highlighting performance by using PCRE2’s JIT capability.

    However, that left us in an odd place with how GtkSourceSearchContext works for regex-enabled search. It was using GRegex which itself uses PCRE (1). It’s pretty clear that the goal is to completely deprecate GRegex in GLib and it’s days are numbered. In particular, there is a lot we can’t do to control the execution environment and protect against things like stack overflows. Worsening things, PCRE doesn’t appear to be maintained these days.

  • Maximiliano Sandoval: GSoC 2021 and GNOME Design tools

    This Google School of Code, I decided to work with Bilal Elmoussaoui as a mentor, the goal being updating some GNOME design tools to GTK 4, specifically Icon Library and App Icon Preview. Both apps are written in Rust and make use of the gtk-rs bindings for gtk.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
