About this episode

The episode discusses the drawbacks of using inline math in configuration files and advocates for better documentation practices.

Ever feel the urge to write out calculations in your code to make them "self-documenting"? In the latest episode of the No Compromises podcast, we discuss why inline math in configuration values is a habit worth breaking. Aaron argues that if a value never changes, there's no reason to calculate it every time. A well-placed comment can explain how you got the number without the unnecessary overhead. We also cover how comments can clarify units like seconds versus milliseconds, why this thinking applies beyond config files, and how questioning small habits can improve your code overall.
