I have no problem installing VirtualBox and the related tools and extensions in Ubuntu and Arch. In Fedora, things are a little bit harder. First, I think it’s better NOT to download binaries distributed by VirtualBox: I’m using Fedora packages that are available from RPM Fusion Free. Thus, first of all, you have to enable […]
TL;DR If you want to access your Google Calendars from Korganizer or Kalendar, remember to enable “Enable the KDE wallet subsystem”. I had already written about the cumbersome procedure to access Google accounts in KDE, and I thought I had learned enough to “easily” set my Google calendars in KDE. I was wrong. Today I […]
I use VirtualBox a lot for testing purposes, mainly to experiment with a Linux distribution (to see whether it’s worthwhile to install it on bare metal) and to test procedures that might involve some complex (and maybe “dangerous”) operations. After you install VirtualBox Guest Additions, things like bidirectional copy-and-paste will work. Some distributions seem to […]
Recently, I started to contribute and maintain Pitclipse, an Eclipse plugin for running mutation testing with PIT. We needed a mechanism to detect whether JUnit 5 is in the classpath of a Java project (so that we could run PIT with its JUnit 5 plugin). The first implementation of such a mechanism was rather cumbersome […]
I’ve always been using GIMP for cropping images (for articles, books, etc.), and it works pretty well, but I never thought that you could do the same much quicker with the default image viewer of KDE, Gwenview. In KDE Plasma, I’ve always used Gwenview as an image viewer, but it’s much more: Gwenview is a […]
I’ve always been using the locate command (provided by the mlocate package or by the new plocate package), which quickly searches for files and directories by their names. The command relies on the database built by the command updatedb (which should be run periodically, e.g., by enabling the plocate-updatedb.timer service for plocate). Unfortunately, by default, […]
If you update to Xtext 2.27.0 and have compiler tests for your Xbase DSL that assert the output of the compilation, you’ll get lots of failures after the update. I am guilty of that 😉 Well, for a good reason, at least 🙂 In fact, I worked on this issue: https://github.com/eclipse/xtext-extras/issues/772 and its fix is […]
Pacman is the package manager in Linux Arch and Linux Arch-based distributions. I’ve been using EndeavourOS for some time, and I enjoy it. EndeavourOS is pretty close to vanilla Arch. I also experimented with pure Arch (more on that in future blog posts). However, the output of pacman in EndeavourOS is much more excellent and […]
Maybe this is well-known to macOS users, but it wasn’t clear to me as a Linux user. As a Linux user, I’m used to using Alt+Tab to switch between different windows. But I also use the shortcut to switch between different windows of the same application. In Gnome, the shortcut is Alt+<the key above Tab>, […]
Now that Gnome 42 has been released and available in most Linux distributions, I started experiencing problems with the Dropbox icon in the system tray. First of all, I have no problem with Ubuntu 22.04, which comes with the extension “AppIndicator and KStatusNotifierItem Support” https://extensions.gnome.org/extension/615/appindicator-support/. Moreover, I think the problem is not there because, while […]
I recently bought an LG GRAM 16 and I really enjoy that (I’ll blog about that in the near future, hopefully). I had no problems installing Linux, nor with Manjaro Gnome (Phavo) neither with Kubuntu. However, in Manjaro Gnome I soon started to note some lags, especially with the touchpad and some repainting issues. I […]
I recently bought a PineBook Pro (maybe I’ll review it in the future in another post). What annoyed me first was that the right click on the touchpad with a two-finger tap was basically unusable: you should be extremely fast. In some forums, the solution is to issue this command

I recently started to port all my Java projects from Travis CI to GitHub Actions, since Travis CI changed its pricing model. (I’ll soon update also my book on TDD and Build Automation under that respect.) I’ve always used caching mechanisms during the builds in Travis CI, to speed up the builds: caching Maven dependencies, […]
In all my computers I have dual boot, Ubuntu and Windows, though I’m using the former 99% of the time 😉 On one of my laptop I started to evaluate also Manjaro (probably a blog post will come in the near future). I let Manjaro install the main efi grub boot loader and I noticed […]
Before releasing Maven artifacts, you remove the -SNAPSHOT from your POMs. If you develop Eclipse projects and build with Maven and Tycho, you have to keep the versions in the POMs and the versions in MANIFEST, feature.xml and other Eclipse project artifacts consistent. Typically when you release an Eclipse p2 site, you don’t remove the […]
If you like to use KDE you probably install Kubuntu directly, instead of Ubuntu, which has been based on Gnome for a long time now. However, I like to have several Desktop Environments, and, now and then, I like to switch from Gnome to KDE and then back. Currently, I’m using Gnome for most of […]
Especially with lambdas, you may end up with a chain of method calls that you’d like to have automatically formatted with each invocation on each line (maybe except for the very first invocation). You can configure the Eclipse Java formatter with that respect; you just need to reach the right option (the “Force split” is […]
In this post I’ll show how to add an Eclipse launcher as a favorite (pinned) application in the Gnome dock (I’m using Ubuntu Artful). This post is inspired by http://blog.ttoine.net/en/2016/06/30/how-to-add-eclipse-neon-launcher-in-gnu-linux-menus-and-launchers/. First of all, you need to create a .desktop file, where you need to specify the full path of your Eclipse installation:

HiDPI support in KDE Plasma has been recently improved! I’m afraid what’s not improved is the procedure for using that. In this post I’ll detail the steps to use HiDPI with KDE if you have a high resolution display (for example, I have that in my Linux Dell M3800). Remember that the settings you change […]
After I upgraded my Dell Precision m3800 to the new Kubuntu Wily 15.10 I had a very bad surprise: the screen was continuously flickering in a way that it was unusable. This happens only if you are NOT using the default highest resolution 3200×1800 which, at least for me, is really too small. I thought it was […]
