Since this is Hacker News I am going to take issue with some technical points. This is not a new knot, it is simply a reef knot with the ends slipped. Generations of sailors know it as a way of reefing (reducing the area of) sails . What this is, is an alleged new method for tying a reef knot with the ends slipped more quickly than the boy scouts 'left over right, right over left' method. I think this is an important distinction.
Actually I love this site! Does one thing, and does it well.
