Performing Effective Code Reviews – A Checklist

Leider ist der Eintrag nur auf English verfügbar.A few years ago, software architect Surender Reddy Gutha compiled a - still quite relevant - Code Review Checklist. All too often, when performing code reviews, we as software engineers tend to focus on minute details such as code formatting rather than the big picture, non-functional requirements, or architecture and security considerations. Perhaps, the problem already originates with the term code review: Rather than reviewing code we are - or should be - reviewing the ...

Artur Śmiarowski’s Guidelines for Writing Readable Code

Leider ist der Eintrag nur auf English verfügbar.Code means communication has become a bit of a mantra for me.
