Let’s install Ubuntu 25.04 on Apple Silicon (M1) in a virtual machine using UTM. We must first download an Ubuntu ISO for ARM. Go to https://ubuntu.com/download/desktop and search for “ARM 64-bit architecture”; if not available for the specific version you want to install, then you’ll have to install the Ubuntu Server and then install the “ubuntu-desktop” […]
On some computers, like the new Dell Pro Max Tower T2 and the old XPS 13, the SATA operation mode for the SSD is set to RAID by default. Linux will not be able to see the SSD in RAID mode: you need to change it to AHCI. If you just change it to AHCI […]
If you’re a KDE user who wants to keep your desktop configuration under version control, you’ve probably discovered that KDE’s configuration files can be quite challenging to manage with traditional dotfile tools. KDE stores settings in complex INI files that frequently change, contain system-specific data, and include sections you may not want to track. This […]
I bought this laptop in late 2016. It’s still a good laptop (8 GB RAM, 128 GB SSD) and very light. However, I cannot use it with macOS anymore. I previously blogged on installing Ubuntu on my old MacBook Air. Everything mainly went smoothly, except for the WiFi, which was not working during and after the […]
This is the first part of a few tutorials on using the LaTeX typesetting system with Neovim using the LazyVim setup. I highly recommend LazyVim because it has many cool plugins configured with nice defaults. Moreover, as we see in this tutorial, it lets you quickly have VimTeX and the TexLab LSP up and running […]
I bought this laptop in late 2016. It’s still a good laptop (8 GB RAM, 128 GB SSD) and very light. However, I cannot use it with macOS anymore. Let’s put Ubuntu Linux on the laptop! I’ll write the installation instructions and the configurations for a fully functional Ubuntu on this MacBook Air, which runs […]
This is the fourth part of a few tutorials on Java development with Neovim using the LazyVim setup. This post assumes you have already read and applied all the steps of the first, second, and third parts. You need Java installed (possibly 21), while Maven is optional. I will use this Maven example during the […]
This is the 5th post about using Java in Gitpod. It assumes you have already read the first, second, third, and fourth posts. We can benefit from automatic formatting. First, select (from F1) the command “View: Toggle Render Whitespaces”. We can see that the Maven archetype generated Java source code with spaces for indentation: I prefer […]
This is the third part of a few tutorials on Java development with Neovim using the LazyVim setup. This post assumes you already read and applied all the steps of the first part and the second part. You need Java installed (possibly 21), while Maven is optional. I will use this Maven example during the […]
Up to now, I have shown how to get started with Sway with the initial configurations and some other configurations. Now, I’ll show how to install another status bar in Sway: Waybar (which is more powerful than the default Sway bar). Again, I’m going to do that for Arch Linux. As in the previous posts, […]
This is the second part of a few tutorials on Java development with Neovim using the LazyVim setup. This post assumes you already read and applied all the steps of the first part. You need Java installed (possibly 21), while Maven is optional. I will use this Maven example during the tutorial: https://github.com/LorenzoBettini/maven-bank-example, part of […]
Let’s continue the Sway window manager (in Arch Linux) series I started in my previous post and continued in the other post. Screenshots We can use “grimshot”, part of sway-contrib, to take screenshots, which requires the main program for performing the actual screenshot, “grim”.

sudo pacman -S sway-contrib grim |
By default, such utilities are installed in “/usr/share/sway-contrib”, which is […]
Updated 16 December 2024 (for Telescope) This is the first part of a few tutorials on Java development with Neovim using the LazyVim setup. I highly recommend LazyVim because it has many cool plugins configured with nice defaults. Moreover, as we see in this tutorial, it lets you quickly have the Java LSP up and […]
Let’s continue the Sway window manager (in Arch Linux) series I started in my previous post. In this post, we deal with system notifications. (This post is similar to the corresponding one about Hyprland.) We use mako, a lightweight notification daemon for Wayland, one of the optional software suggested when we installed Sway. We also […]
This is the 4th post about using Java in Gitpod. It assumes you have already read the first, second, and third posts. Let’s now use the POM editor to update the version of JUnit (the Maven archetype is based on an old version of JUnit). When we open the “pom.xml” in the editor, we get a […]
I’m starting a new blog series about Sway, a Wayland Tiling Window Manager (the Wayland version of i3). Though I’ve already blogged about Sway, this post (and a few future ones) are intended as “getting started tutorials”. I’ll focus on Sway in Arch, in particular, EndeavourOS. Let’s start by installing EndeavourOS with no graphical environment […]
This is the 3rd post about using Java in Gitpod. It assumes you have already read the first and second posts. On the bottom, we can see that there are two warnings on our project; let’s click the icon and see them in the “Problems” tab: Since this is not a Java project managed by […]
I have already blogged about installing EndeavourOS ARM on a PineBook Pro (and previously, directly Arch ARM: the first article and the second article). This blog post will describe the new procedure for installing EndeavourOS ARM on a PineBook Pro. As usual, the instructions can be found here: https://endeavouros.com/endeavouros-arm-install/. Previously, there used to be three possible […]
Recently, I blogged about using KDE applications in Hyprland. I also blogged about theming and styling them. However, I’m not very happy with that solution, so I’ll provide a possible alternative, which, in my opinion, is better. Some of the steps are similar to the ones in my previous post. I assume you’ve already installed […]
I have already blogged about multibooting several different Linux distributions with GRUB. This post is a simplified and updated version of the previous post. Moreover, I made it easier to test such configurations manually: install several Linux distributions in a single KVM virtual machine. In this post, I’ll show how to configure GRUB (without os-prober, […]
