Every programmer eventually meets the duck.

Not because the duck has the answers—but because explaining the problem out loud often reveals the solution before anyone (or anything) responds.

It's one of programming's best-kept traditions, and if you've ever debugged code by talking to a rubber duck, you already understand the joke.

Rubber Duck Logic is a tribute to one of the most effective debugging techniques in software development. No complicated algorithms. No AI. Just a patient listener and a fresh perspective.
