- Write tools to simplify a programming task, even if it means throwing away the tool later.
Rule of Simplicity: Design for simplicity; add complexity only where you must.
-
One of the most important aspects of writing software that remains maintainable long-term is keeping its global complexity down.
-
Software is robust when it keeps on performing well under unexpected conditions. Software that isn’t robust is usually the result of it being too complicated to understand by a developer. This means that robustness is the result of transparency and simplicity.
