Simon Tournier's projects

You can help free software by supporting freelance developers: for instance, Mathieu focused on maintaining GNU Guix and taking care of the continuous integration (among others). Or by supporting infrastructure maintainers: for instance, the decentralized Mastodon instance Sciences.Re administred by Rémy.

GNU Guix
Guix HPC (= Guix scientific context)
French chapter of Reproducible Research network
~~Guix Workflow Language (GWL)~~ (pause)

IRC: zimoun @ irc.libera.chat hanging out #guix or #guix-hpc.

Past interests: Scientific tools GetDP (FEM), Gmsh (mesh), Bempp (BEM) and various Krylov solver implementations; to name some. Aside, I have been involved with Colombbus and specifically with Declick; which, among others, is promoting computer sciences in junior secondary school using Free Software.

As an avid Emacs user, I have spent uncountable amount of time tweaking my config, writing emacs-lisp, etc.

And away from keyboard, my list of hiking project is endless, mainly in the The Pyrénées.
