I am a Software Engineer living in Paris, France. I usually spend my time programming or having fun in a terminal. In love with GNU/Linux and FOSS (RMS's website is a gold mine everyone should read). I like writing in LaTeX. And I also play the guitar.

Apart from computers, I am also interested in space exploration and rockets, AI and self-driving electric cars. I look forward to a future with a lot less pollution.

I try to read books as often as possible, in English and French. I am also a huge fan of comics.

I write blog posts quite extensively on this website, not only about computer science but also broader topics such as the environment, my travels or politics. There are RSS and Atom feeds that you can subscribe to. I usually write a few times a month. Feedback is greatly appreciated.

In this article, I'll walk you through the most iconic...

  3. Belgium

    In late 2015 I went for the first time of my life to Belgium... for a very short time, 24 hours actually. The only city I got to see and walk in was Brussels. I'll likely update this article in the future when I get the chance to go back to Belgium. When I went there, it was shortly after the November 2015 Paris attacks. The police was actively...
