One of my favorite features in the fish shell is the ability to define abbreviations using the abbr command.

I previously shared my experience in moving to the Fish shell during the last quarter of 2025.

I have been aware of the Fish shell for many years.

Lots of things have been going on in the background, and posting content to my personal website hasn’t been a big priority of the last (few) years!

What is Podman?

I had been randomly exposed to conventional commits as part of my opensource activities, not really paying attention to this weird form of commit messages.

The Java Reactive Streams APIs have been part of the JDK since Java 9.

Go 1.18 recently introduced test fuzzing, so I decided to give it a go (no no, I’m not making a stupid joke).

Git is a fantastic tool to manage source code.

I was recently puzzled by flaky tests in Mutiny.

I presented today a new publication called Analysing the Performance and Costs of Reactive Programming Libraries in Java at the 8th ACM SIGPLAN International Workshop on Reactive and Event-Based Languages and Systems (REBLS) (a workshop of Splash 2021).

I am happy to announce that my upcoming book Vert.x in Action: Asynchronous and Reactive Applications in Java is now available in early access at Manning!

Two years ago I ventured into spending some time in industry.

It seems like the whole Java ecosystem is going mad these days with GraalVM.

I am very happy to announce that I am joining the Vert.x team at Red Hat starting next Monday!

I am in favor of using contributor license agreements (CLA) for opensource projects that are expected to be developed in the long run, especially when you develop them as part of your professional activities.

Update 2014/04/29: for the record Boon is the new JSON implementation for Groovy. groovy in the benchmarks actually refers to the old implementation.

The other day I stumbled upon a retweet on the anger of Pierre Joye against contributor license agreements (CLAs): @github you should put a red button on any repo requiring a CLA to contribute so we don't even bother trying to contribute. — PierreJoye (@P…

So… I started writing this while in the train to Lyon going back from the Devoxx France 2013 conference held in Paris.

The release of the Mozilla Public License Version 2.0 probably flew under the radar when it happened in January 2012.
