My Principles

Over the past years, I've discovered some principles that helped me increase the reliability and maintainability of software, and I strongly attach importance to them.

  1. Build often and early. Release often and early.
  2. Prefer simple, avoid clever.
  3. If clever cannot be avoided, it has to be well-documented.
  4. Don't implement it if you haven't been asked for it.
  5. Special cases aren't special enough to break the rules.
