Voxxed Days Luxembourg 2022 Room: AmigaOS Type: Conference Most of us do code reviews very often if not daily. However, how can we tell whether we are good reviewers or not? Do we review a code as robots? Do we keep in mind that we are reviewing the code of someone who invested time and knowledge to write this code, and thus deserves to get respectful feedback?

Furthermore, we explain the keys of the code review process answering the question Why? When? Who? Where? What? and How? To discover more about all these points and more, come and see our talk.
