Utopie du logiciel libre
Du bricolage informatique à la réinvention sociale
de Sébastien Broca

"This is a bold claim, But I stand be­hind it: if you learn and fol­low these five ty­pog­ra­phy rules, you will be a bet­ter ty­pog­ra­ph­er than 95% of pro­fes­sion­al writ­ers and 70% of pro­fes­sion­al de­sign­ers. (The rest of this book will raise you to the 99th per­centile in both categories.)
All it takes is ten min­utes—five min­utes to read these rules once, then five min­utes to read them again."
