I moved in a new house with my girlfriend in the middle of 2025. After living 15 years in a nice apartment, it is the occasion to build a nice homelab. I had self-hosted services since 2004, but the server has always been an old desktop, a slow QNAP or that one Zotac ID11 that still refused to give up after 10 years, and now a refurbished Zotac CI540 Nano . I've wanted a nice server and network…
Récap Cela fait quelques mois que je n'ai plus posté ici. Mon activité technophile a diminué ces derniers temps, pour plusieurs raisons. La première est que je n'ai plus de gros projet informatique en cours. Je continue de maintenir et d'utiliser au quotidien AgayonTodo et AdComo . J'utilise toujours XMPP au quotidien pour récupérer un résumé de mes logs à l'aide de Logwatch . Mon prochain projet…
Ad Como (To Do in latin) is a small Golang application written to handle simple to-do lists. As AgayonTodo became more and more reliable, I wanted to have access to my to-do notes everywhere. It is mobile-friendly and responsive, but the server on which it is installed is not always up for various reasons. Moreover, I wanted to try to develop a mobile application for a long time. I developed a…
For years, I have used myTinyTodo to manage my to-do lists. It is super light, fast and easy to use. At some point, I struggled to update it to use my up-to-date version of PHP. Last year, I wanted to explore other languages than Python. I decided to start a small project to replace myTinyTodo. As I wanted to explore Go and React , I created two projects to build my to-do list system. The project…
First I would like to wish all the readers (if there is any), a merry Christmas and a nice happy end of year. The time flew since the last article.

My First Thinkpad T First, I bought a refurbished Levovo Thinkpad T480s . It…
Pendant mes trajets en voiture, j'aime écouter des podcasts. Ma voiture supporte la connection Bluetooth avec un téléphone mais pour diverses raisons, je préfère utiliser une bonne vieille clé USB. Je récupère les épisodes à l'aide de l'application GNOME Podcast qui récupère les flux RSS/Atom. Les scripts ci-dessous me permettent d'écouter La semaine des 5 heures pendant des heures, étant donné…
It's been a long time since I updated this blog. It will be a short update post about two projects. chatty_server The first is chatty_server, a small XMPP bot I use to interact with my server.

Anybody can add the bot…
Today, I was lucky to be invited in the school of the Hospital Mont Légia in Liège. It was an afternoon session following their science course to present the Agayon to children and teenagers (~6 to 16 years old). They follow their schooling while being hospitalized. I was contacted by a friend of a friend who works there as a physics teacher. He likes to organize interactive sessions with the…
It's been a while since I first installed prosody on Agayon.be. I use it to experiments with my bots, to keep contact with the XMPP community and discover new cool stuffs to do. Recently I struggled a bit because I wanted to hide the prosody small HTTP server behind my Proxy. For various reasons, I still use Apache 2.4 and I could not get it to work with prosody. I mostly use the HTTP server for…

My model cannot be used with vanilla…
Converse is a JavaScript XMPP client that can be run in a web browser. Unfortunately, it does not support the XMPP extension (XEP) that allows to verify HTTP Requests via XMPP (XMPP): XEP-0070 .

... et devient compatible avec Windows. Précédement sur ce site, je vous ai présenté le logiciel Opus . Il s'agit d'un système de publipostage permettant d'automatiser la recherche d'emploi. Ayant reçu des demandes pour le porter sous windows, j'ai réalisé un portage sous forme d'un fichier exécutable auto-extractible. Pour les plus néophytes, on clique et ça se lance.
Previously on agayon.be , I mentioned a new small project: a SLAM device. It was finished recently and this article presents its final form. After many trials, the chosen design includes an optical rotary encoder disk with 360 teeth in order to provide a theoretical resolution of one degree. The Arduino code sends the data through serial connection in a compatible way with the xvlidar library .…
