FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

Using the graph to control unique id generation

Introduction

This gist was prompted by Nigel Small’s tweet of a query to generate a unique id for a node (and is posted here with his agreement). It inspired me to think about how it could be used in a full example, unrestricted by Twitter’s 140 characters. I have also looked at how we could generate different sets of unique ids for different labels.
