In the continuity with the previous post about jp, the following article present sat_pubsub, a XMPP Publish-Subscribe (Pubsub) Service Component, build for the need of the « Salut à Toi » project.

Salut à toi (SàT) is a unique XMPP client. As its official description says, it's a "multipurpose, multi front-end, free (libre) and decentralized communication tool". It has been actively developed by Jérôme Poisson (Goffi) and Adrien Cossa (Souliane) since 2008.

sat_pubsub allows us to use our own up-to-date persistent pubsub service.

This article is composed of several sections

• Why sat_pubsub ?
• Let's install it !
• Let's use it !
• A note about Agayon XMPP service
• Future of SàT
• Links

Salut à toi is a unique XMPP client. As its official description says, it's a "multipurpose, multi front-end, free (libre) and decentralized communication tool". It has been actively developed by Jérôme Poisson (Goffi) and Adrien Cossa (Souliane) since 2008. Today, I will focus on the use of "JP", a command-line interface. It can be used to send or receive files directly from a shell, pipe commands to or from XMPP, use XMPP easily in a script and of course play with pubsub nodes.

Finding a job may be a time and energy-consuming task. Opus is a program written to help people to send their application more easily. It can be used to generate personalized cover letter. I began to write it several years ago and I took the time to enhance it with the aim to help other people.

... 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. Therefore, the lidar module can be used with the BreezySLAM module of Simon D. Levy. Moreover, the data are being sent through XMPP to another computer where the map can be plotted.
