> But why 4 times? When I originally shared this in 2022, it was just a comment here: https://news.ycombinator.com/item?id=30146019#30146451 https://news.ycombinator.com/item?id=30146019#30146451 I didn't expect it to get much attention, so I went with four beeps. I felt that a set of four beeps spread over three seconds would be long enough to grab my attention, even if I was busy with something else. Also, as another commenter pointed out, a sequence of four beeps is distinctive enough that it doesn't get lost among the stray, ordinary beeps I might hear while working in a terminal or Emacs (like from hitting backspace or pressing ctrl+g, etc.).
