Logging

Logging is a major pillar for well-designed applications. It is not only a large help during development but also critical for failure analysis and debugging. The most effective debugging tool is still careful thought, coupled with judiciously placed print statements. - Brian W. Kernighan Further logging is essential for observability in production. Nonetheless, I often encounter codebases with lousy logging practices. This manifests itself in useless logging missing context or in over-logging thereby bringing down the whole system.
