Unison, a powerful file synchronizer, has long been one of my favorite tools. However, installing Unison on macOS used to be a manual and sometimes cumbersome process, as detailed in my earlier guide. The great news is that Unison is now available as a Homebrew cask! This means you can install it with a single […]
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 […]
Zram, https://www.kernel.org/doc/html/latest/admin-guide/blockdev/zram.html, is a Linux kernel module that creates a compressed block device in RAM. This device can be used as swap space or a general-purpose RAM disk. By compressing data in memory, zram allows your system to store more data in RAM, reducing the need to swap to slower disk storage and improving overall […]
I like Nerd Fonts a lot, and blogged about those in the past. If you spend a lot of time in the terminal, you’ve probably heard of them: they patch popular programming fonts with a huge set of icons, making your terminal and development environment look great and more informative. Here’s how you can easily […]
If you use Lazygit as your terminal Git UI, you know how convenient it is for staging, committing, and managing branches. I use it in Neovim (LazyVim already configures it). Integrating a custom pager (Lazygit Custom Pagers Documentation) can dramatically improve how diffs are displayed. In this blog post, I’ll document how to use delta: […]
When working with Maven projects, the Surefire plugin is commonly used to execute tests, but it lacks a built-in feature to display the total execution time across all test suites. This can be particularly important when monitoring performance trends in larger projects with many test classes. Maven’s Surefire plugin reports execution time for individual test […]
I’m going to show you how to use Neovim on Gitpod. This can be useful for checking and testing your Neovim configuration. The example can be found here: https://github.com/LorenzoBettini/neovim-gitpod-example. I’m using a LazyVim distribution as a demonstration. The Gitpod custom Dockerfile, “.gitpod.Dockerfile”, must be tweaked to install Neovim and its requirements (especially for using Lazyvim):

Using “pip” is the supported installation method for Ansible and Molecule. Let’s install Python libraries and applications (in this case, Ansible and Molecule) in a Python virtual environment. (This post is similar to the one about Ubuntu.) First, install the required packages, including the Python virtual environment package:
|
1 |
sudo pacman -S python-pip python-virtualenv |
Create a virtual environment somewhere (in […]
I experimented with Copilot “Agent mode”: I told it to create a Maven plugin. (Let me stress that I already have some experience implementing and testing Maven plugins.) I’ll report my experience, which has been positive in some respects but disappointing in others. I use “Claude 3.5 Sonnet” model because that’s the one used in […]
The “remote” feature of flash.nvim is handy: it acts in “operator pending mode” to perform operations and then return to the original position. It took me some time to understand what it was doing, so I’m writing about it. I’m using it in the LazyVim distribution, which enables “flash” by default (and also “which-key”, which […]
Using “pip” is the supported installation method for Ansible and Molecule. In Ubuntu, just using “pip” will lead to the error “externally-managed-environment” because of the Python environment that is “externally managed” by the package manager (this prevents direct use of pip for system-wide installations to avoid conflicts or issues). (This post is similar to the one […]
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 […]
Similar to what I had already shown in a previous post, in this post, I show how you can install (and keep up-to-date) the “tpm” (Tmux Plugin Manager) with Chezmoi, which I highly recommend! Typically, you manually install “tpm” by cloning its GitHub repository into the proper directory:
|
1 |
git clone https://github.com/tmux-plugins/tpm ~/.tmux/plugins/tpm |
Let’s do that automatically with Chezmoi instead. Chezmoi […]
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 […]
I like the tracker service in Gnome, which indexes files so that you can easily search for them from the Activity view or the file manager. However, I don’t like tracker-extract, which also indexes the file contents: I use Recoll for such a service, and tracker-extract uses too much CPU (it indexes new or modified […]
Updated on 26 March 2025 with more screenshots about the new font. GNOME 48 has just been released on Arch Linux! (And thus, also on EndeavourOS). Unfortunately, many extensions have been turned off because they are not yet compatible (that’s quite usual with new versions of GNOME): The most critical one is the first one […]
Microsoft announced the public review of Copilot for Eclipse. I immediately tried that in one of my Java projects. Use the “Market Place” to install Copilot in Eclipse: Once you click install, you must “trust” the contents to be installed: Once installed and restarted Eclipse, you must authenticate with your GitHub Copilot account by clicking […]
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, […]
I’ll briefly review the (currently in alpha 6) Cosmic DE in Pop Os 24.04 from System76 implemented in Rust. The installation is smooth and easy to follow, based on standard dialogs: I’m selecting “Clean Install” here because I’m testing it on a virtual machine. There’s also the chance to encrypt the drive, but I’m not […]
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 […]
