What you will find here
The site keeps two distinct sections.
Articles are long-form pieces: field reports, analyses, architecture notes. They rest on what was actually built, tried or broken in real conditions.
Gems form a catalogue of open-source tools, self-hostable projects and libraries. Each entry is short and serves one purpose: letting you decide in a minute whether a tool is worth reading the documentation for.
Both sections exist in French and English. The English versions are written, not machine-translated.
