Zert is a pure-Zsh plugin manager built around a simple idea: your plugins should be declared directly in your .zshrc, pinned to exact commits, and reproducible on any machine just like npm does for Node projects. This project can be found on this GitHub repo. Let's see some commands: zert zert # zert manages itself zert use ohmyzsh # enable Oh-My-Zsh

Today I used Fedora 44 beta 12 server on VirtualBox, and I wanted to test how Python works with Django on this Linux distribution. In the Fedora distribution, I have Python version 3.14.3 and Django version 6.0.4. I created a basic project with multiple pages, CSS, JavaScript, and an admin interface. It seems that Django is functional, and the result is very good for a basic project.:

The old laptop on which I was running Fedora broke down. That didn't stop me from testing Fedora Server version 44 beta 12 with the Budgie environment in VirtualBox, and I also made a beginner tutorial video that I share on my YouTube channel - Catalin George Festila. See this video:

Today, I saw this good environment and will test with Fedora server on virtualbox because I don't have hardware to test it. You can see more about this with the Fedora Spin. The Fedora Budgie Spin showcases the Budgie Desktop, a feature-rich, modern desktop designed to keep out the way of the user. Budgie Desktop uses common desktop design metaphors while offering users sophisticated

Fedora 43 won't support Xorg, the distro's. All GNOME X11 session users will be migrated to the Wayland session. Fedora 43 will ship with Python 3.14, Linux Kernel 6.17, KDE 6.4, and RPM 6.0. It will come with Mesa 25.1.4 graphics drivers. Beta builds of Fedora 43 Workstation, KDE Plasma Desktop, Server, IoT, and Cloud are available for download on the distro's website.

Fedora 42 is a version of Fedora released to the public on 15 April 2025[1], under the codename "Adams". This version is notably the first version since Fedora 23 to use a codename. This version updates GNOME to version 48. See the wikipedia article. Yesterday I installed the Fedora Linux distro with version 42 also known as Adams, on the old Cosmic environment. The packages were installed

It remains my favorite linux distribution so far. I didn't have time to work with Fedora, I see the development team initiated a larger plan over a longer period of time, which is very good. Fedora Linux 41 End of Life will be on Wed 2025-11-19 and Fedora Linux 43 End of Life will be on Wed 2026-12-02. Now : Notify Mirrors of Final Release , see this schedule.

Today I tested the perf tool in Fedora 41 and it is a bit difficult to use. I documented myself and found some information on the web and in the online linux community. Here is what I thought was worth remembering and what I tested. The performance of Python with `perf` support is not great, and is going to get a lot worse.
