Opensource enthusiast and advocate since the late '90s.
My personal computers run 100% Linux since 2000 (Kubuntu since 2005-2010) as well as my professional laptop since 2019 (at last !).
I was trained to Unix and Minix during my engineer learning curriculum in the early '90s.
Photographer and former member of the Piwigo development team (https://piwigo.org/), a photo gallery developed at a time when online photo gallery almost didn't existed. All my photography related software is still opensource.
I still code in Bash script and sometimes in groovy (Freeplane plugins) and Lua (Darktable plugins)
