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 […]
In this post, I’d like to share my thoughts and the solution I adopted to circumvent the terrible incident that happened a few days ago with grub in Linux Arch. The bug affected all Arch-based distributions (not Manjaro, which is not really Arch-based, but for sure EndeavourOS and Arch itself). You can find the details […]
Crystal Linux is a brand new Linux distro based on Arch. Although it has not been officially released, you can already download an ISO and try that in its current development state. Quoting from its home page: Crystal Linux is a brand new Arch Linux based distribution. Powerful and easy to use. And, in particular […]
I installed Ubuntu Jammy a few months ago, when it was released, on a desktop computer. It was a terrible experience: crashes now and then, and the Wayland session was not working well on some applications. After a week, I uninstalled it immediately and switched to Fedora on that computer. Then, a new point release […]
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 […]
After using EndeavourOS for a while, I also decided to try Arch itself! I did not feel ready to go through the manual procedure (but I’ll do that someday), and I heard about the archinstall script, which comes in the Arch official ISO. After watching a few videos and reading a few blog posts, I […]
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, […]
I have already blogged about EndeavourOS, which I use most of the time on a few laptops. Since EndeavourOS, based on Arch, is a rolling release, I update it almost daily and don’t need to install it from scratch when a new release comes out, like Artemis, which was released a few days ago. However, […]
I had already posted about enabling hibernation in Linux, particularly in Ubuntu. Thanks to the script hibernator, the procedure is much more straightforward in Arch-based distros (including Manjaro and EndeavourOS). First of all, make sure you first install the package update-grub. The package hibernator is available from AUR, but currently, there’s a problem with the […]
UPDATED 02/Jan/2023, ChangeLog: 02/Jan/2023: documented that the new version of grub-btrfs is now an official package (you still have to install another package: inotify-tools); 02/Dec/2022: documented the new version of grub-btrfs and its new grub-btrfsd daemon; the configuration for Timeshift is much simpler, but you have to install another package: inotify-tools. After looking at the […]
After the recent release of KDE Plasma 5.25, this version landed a few days ago in Arch-based distros like EndeavourOS (the one I’m writing from). Although I’m mostly a GNOME user, I also have a few distributions installed where I’m using KDE Plasma. The new features that impressed me most are related to eye candies […]
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>, […]
It looks like KDE Plasma is getting usable with Wayland! This is my current testing environment for this blog post: Operating System: EndeavourOS KDE Plasma Version: 5.24.5 KDE Frameworks Version: 5.94.0 Qt Version: 5.15.4 Kernel Version: 5.15.41-1-lts (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i7-8550U CPU @ 1.80GHz Memory: 15,3 GiB of RAM […]
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 […]
Fedora 36 has just been released, and I couldn’t resist trying it right away. I had already started using Fedora 35 daily (though I have several Linux distributions installed), and I’ve been enjoying it so far. Before upgrading my Fedora 35 installations, I decided to install Fedora 36 on a virtual machine with VirtualBox. These […]
I had previously written about mirroring Eclipse p2 repositories (see this blog tag), but I’ll show how to do that with Tycho and one of its plugins in this post. The goal is always the same: speed up my Maven/Tycho builds that depend on target platforms and insulate me from external servers. The source code […]
4th July, updated with BTRFS installations. Besides Windows (which I rarely use) on my computers, I have a few Linux distributions. Grub 2 does a good job in booting Windows and Linux, especially thanks to os-prober, in autodetecting other operating systems in other partitions of the same computer. However, there are a few “buts” in this […]
After playing with VirtualBox (see my posts), I’ve decided to try also KVM (based on QEMU) and Virtual Machine Manager (virt-manager). The installation is straightforward. In Ubuntu systems:
|
1 |
sudo apt install virt-manager bridge-utils |
In Arch-based systems:
|
1 |
sudo pacman -S virt-manager qemu edk2-ovmf |
Then, you need to add your user to the corresponding group:
|
1 2 |
sudo adduser ${USER} libvirt sudo adduser ${USER} libvirt-qemu |
Reboot, and you’re good to go. In this post, I’m […]
