The Little Printf
> One day, I was stuck in an airport coming back from a conference, furiously typing at a terminal, when an odd, gentle voice asked me:
> If you please, design me a system!
> Design me a system!
> I looked up from my screen, surprised by the request. I looked around and saw this kid who aspired to be a developer and wanted me to call him “printf”, which I felt was very stupid and gimmicky.
