I still haven’t tried to install the pure Arch distribution, but I learned about EndeavourOS, an Arch-based distro, which is pure Arch. […]

Using the Unison File Synchronizer on macOS

3 Replies

For ages, I’ve been using the excellent Unison file synchronizer to synchronize my directories across several Linux machines, using the SSH protocol. I love it! 🙂 Unison gives you complete control over the synchronization, and, most of all, it’s a two-way synchronizer. Quoting from its home page: Unison is a file-synchronization tool for OSX, Unix, […]

Problems with Linux 5.13 in LG GRAM 16

3 Replies

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 […]

Eclipse p2 site references

Fixing Right Click Touchpad in PineBook Pro

Leave a reply

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

but then you have […]

Caching dependencies in GitHub Actions

Leave a reply

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, […]

Remove SNAPSHOT and Qualifier in Maven/Tycho Builds

Leave a reply

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 […]

Publishing a Maven Site to GitHub Pages

Leave a reply

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 […]
