I want to share some of my experiences with KDE Plasma Themes in this post. These themes are pretty powerful, but, as it often happens with KDE and its configuration capabilities, it might not be immediately clear how to benefit from all its power and all its themes’ power. I’m assuming that you already enabled […]
I have already blogged about installing Linux on an external USB stick or drive (better if it’s an SSD) to make such an installation portable on any computer. In that old blog post, I was using VirtualBox to do the actual installation. I was relying on VirtualBox because when I had tried to install Linux […]
In this post, I’d like to share my experiences in setting a Google Online Account in GNOME and KDE. Actually, I have more than one Google account, and the procedures I show can be repeated for all your Google accounts. First, a disclaimer: I’ve always loved KDE and I’ve used that since version 3. Lately, […]
Say you publish a p2 repository for your Eclipse bundles and features. Typically your bundles and features will depend on something external (other Eclipse bundles and features). The users of your p2 repository will have to also use the p2 repositories of the dependencies of your software otherwise they won’t be able to install your […]
I had already described the process of publishing an Eclipse p2 composite update site: Publish an Eclipse p2 composite repository on Bintray Publish an Eclipse p2 repository on Sourceforge with rsync Well, now that Bintray is shutting down, and Sourceforge is quite slow in serving an Eclipse update site, I decided to publish my Eclipse […]
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, […]
I have never been able to make hibernation (suspend to disk) work on my laptops (Dell M3800 and Dell XPS 13 9370) on Ubuntu with systemd. The symptom was that running

sudo systemctl hibernate |
was making the system shutdown, but then upon restart the system was not restored: it was just like booting the system from scratch. […]
In this tutorial I’d like to show how to publish a Maven Site to GitHub Pages. You can find several documents on the web about this subject, but I decided to publish one myself because the documents I found refer to a deprecated plugin (https://github.com/github/maven-plugins/tree/master/github-site-plugin) or show complicated settings, also when using the official Maven […]
In this tutorial I’m going to show how to install Linux on a USB drive using Virtualbox. I find this useful to test a LInux distribution. Note that using a live distribution only allows you a small testing experience, while installing Linux on a USB drive will give you the full experience (and if the […]
In this tutorial I’m going to show how to analyze multiple Eclipse plug-in projects with Sonarqube. In particular, I’m going to focus on peculiarities that have to be taken care of due to the standard way Sonarqube analyzes sources and to the structure of typical Eclipse plug-in projects (concerning tests and code coverage). The code […]
This post is based on my Dell M3800 with Linux Neon. KDE already does a good job with touchpad gestures (e.g., two fingers for scrolling, 3 finger tap for pasting, etc.) but it does not support 3 finger swype gestures like in MacOs, e.g., for displaying all the windows or for showing the desktop. Today […]
In this tutorial I’ll show how to use Jacoco with Maven/Tycho to create a code coverage report of multiple Eclipse plug-in projects. The code of the example is available here: https://github.com/LorenzoBettini/tycho-multiproject-jacoco-report-example. This is the structure of the projects: Each project’s code is tested in a specific .tests project. The code consists of simple Java classes doing […]
In a previous post I showed how to manage an Eclipse composite p2 repository and how to publish an Eclipse p2 composite repository on Sourceforge. In this post I’ll show a similar procedure to publish an Eclipse p2 composite repository on Bintray. The procedure is part of the Maven/Tycho build so that it is fully […]
In this blog post I’ll describe my experience in preparing an Oomph setup for a non-trivial Xtext project, Xsemantics. This setup was kind of challenging because of the following features of my project, but I guess most of them can be found in any Xtext project: generated sources are not stored in the Git repository […]
This is the follow up of my previous post about building a custom Eclipse distribution. In this post I’ll show how to deploy the p2 site and the zipped products on Sourceforge. Concerning the p2 site, I’ll use the same technique, with some modifications, for building a composite update site and deploy it with rsync […]
In this tutorial I’ll show how to build a custom Eclipse distribution with Maven/Tycho. We will create an Eclipse distribution including our own features/plugins and standard Eclipse features, trying to keep the size of the final distribution small. The code of the example can be found at: https://github.com/LorenzoBettini/customeclipse-example First of all, we want to mimic the […]
This can be seen as a follow-up post of my previous post on building Eclipse p2 composite repositories. In this blog post I’ll show an automatic way for publishing an Eclipse p2 (composite) repository (a.k.a. update site) on Sourceforge, using rsync for synchronization. You may find online many posts about publishing update sites on Github pages […]
I like to build p2 composite repositories for all my Eclipse projects, to keep all the versions available for consumption. Quoting from https://wiki.eclipse.org/Equinox/p2/Composite_Repositories_(new) The goal of composite repositories is to make this task easier by allowing you to have a parent repository which refers to multiple children. Users are then able to reference the parent repository […]
This is a followup of my previous post, Switching from an inferred Ecore model to an imported one in your Xtext grammar. The rationale for switching to manually maintained metamodel can be found in the previous post. In this post, instead of using an Ecore file, we will use Xcore, Xcore is an extended concrete syntax […]
When you use Xtext for developing your language the Ecore model for the AST is automatically derived/inferred from the grammar. If your DSL is simple, this automatic meta-model inference is usually enough. However, there might be cases where you need more control on the meta-model and in such cases you will want to switch from an inferred Ecore […]
