Hello! I had the presentation with the title in the subject line at the developers unconference some weeks ago. The slides are available here: https://mariadb.org/wp-content/uploads/2018/07/2018-06-27-mariadb-dev-learn-... I recommend all developers skim though them. Debian has some really nice QA systems. All presentations from the event can be found at: https://mariadb.org/tampere-mariadb-developers-unconference-reportback-prese...
