  • Qt packages built with OpenGL ES support are now available

    Some time ago, there was a thread on debian-devel where we discussed how to make Qt packages work on hardware that supports OpenGL ES, but not the desktop OpenGL.

    My first proposal was to switch to OpenGL ES by default on ARM64, as that is the main affected architecture. After a lengthy discussion, it was decided to ship two versions of Qt packages instead, to support more (OpenGL variant, architecture) configurations.

    So now I am announcing that we finally have the versions of Qt GUI and Qt Quick libraries that are built against OpenGL ES, and the release team helped us to rebuild the archive for compatibility with them. These packages are not co-installable together with the regular (desktop OpenGL) Qt packages, as they provide the same set of shared libraries. So most packages now have an alternative dependency like libqt5gui5 (>= 5.x) | libqt5gui5-gles (>= 5.x). Packages get such a dependency automatically if they are using ${shlibs:Depends}.

  • Develop GUI apps using Flutter on Fedora

    When it comes to app development frameworks, Flutter is the latest and greatest. Google seems to be planning to take over the entire GUI app development world with Flutter, starting with mobile devices, which are already perfectly supported. Flutter allows you to develop cross-platform GUI apps for multiple targets — mobile, web, and desktop — from a single codebase.

    This post will go through how to install the Flutter SDK and tools on Fedora, as well as how to use them both for mobile development and web/desktop development.

  • Nobody is Google

    If I understood him right, he meant to say that scalability costs money and businesses flounder on buying more scalability than they need. Or, people think they are Google, but they are not. Even inside Google, only a small fraction of services operate at Google scale (aka planetary scale).

  • 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.
