The new Xbase JvmGenericTypeValidator in Xtext

The new release of Xtext 2.35.0 comes with many new cool features. I personally worked on the introduction of the JvmGenericTypeValidator. Quoting from the release notes: Automatic validation for Xbase languages The new JvmGenericTypeValidator was introduced to automatically perform several Java-related checks in the hierarchy of the inferred JvmGenericTypes of an Xbase language, with the corresponding error reporting.

Dual boot in a KVM Virtual Machine

If you want to experiment with multi-booting in Linux, you might want to consider experimenting with a virtual machine. In this blog post, I’ll show you how to install two Linux distributions on the same KVM virtual machine. I’ll use Fedora 40 and EndeavourOS Gemini. Make sure you download their ISOs. Let’s create the virtual […]

Getting started with Rust with Visual Studio Code

I started learning Rust, and I found Visual Studio Code an excellent IDE for experimenting with Rust (in the future, I’ll also evaluate my beloved Eclipse). I thought I’d share this experience. Assuming you have already installed Rust, let’s create a project

Open Visual Studio Code in the “hello” directory

We get syntax […]

Installing Amarok in Fedora Linux

I have always liked Amarok, the (initially) default KDE media player. It’s very feature-rich, nothing compared to Elisa. Moreover, it has two crucial features that I haven’t found in any other players: it saves statistics (play count and stars) directly into the music file it synchronizes statistics with the iPod. I have always liked Amarok, […]

Getting Started with Gnome Boxes

Gnome Boxes is meant to be an easy and quick-starting software for Qemu virtual machines. I have already blogged about Qemu with KVM Virtual Machine Manager. These tools are powerful but require time to get familiar with them and tweak them correctly (I tried to provide some hints in my previous posts about these tools). […]

Hyprland and notifications with mako

Here’s another post on how to get started with Hyprland. This time, we’ll see how to configure notifications with mako, a lightweight notification daemon for Wayland, which also works with Hyprland. (you might also want to consider and experiment with an alternative: dunst). If you followed my previous tutorials, you have no notification daemon installed. […]

Hyprland: getting started (part 2)

This is the second blog post on getting started with Hyprland (see the first post here). In this article, we install and configure a few other tools. We will also look at the customization of keyboard shortcuts. Other tools As noted here https://wiki.hyprland.org/Useful-Utilities/Must-have/, you need an Authentication Agent: Authentication agents are the things that pop […]

Installing Arch Linux with BTRFS on a PineBook Pro (external storage)

This is a follow-up to the article Installing Arch Linux on a PineBook Pro (external storage); differently from the previous post, this one is based on more automatic mechanisms, so it will be easier to copy and paste commands once a few variables have been correctly and carefully set. Moreover, in this post, I’ll install […]

KVM Virtual Machine Manager and Virtual Machines on external drives

Last year, I blogged about my first experiences with KVM and Virtual Machine Manager. Then, I stopped using KVM because I’ve always found VirtualBox easier for my experiments. In particular, with VirtualBox, it is trivial to store virtual machines on an external drive (I mean, a fast external SD, of course): you specify to use […]
