Elevator Button

I just finished reading the Elevator Button Problem. A short story about how even something as simple as the elevator button needs to be designed.

Even crazier, the article mentions a Paternoster. A sort of elevator that never stops. Watch this video for a demonstration. It does not look safe!

Inspired by a post on Hacker News.
