Burning man is a concert of craziness.
But, there is a machine behind the madness. When you purchase your ticket online at https://burningman.org/ it is possible because of distributed mutual exclusion.
An example of distributed mutual exclusion would include when a ticket is placed by a music goer on a website. The ticket is sent to a group of distributed nodes for processing. The group is just a bunch of nodes that act together for the same purpose. One node grabs the ticket order and dedicates to handling it. Each node gains exclusive access to find out if it has been taken by another note, decides whether to take it and mark that it is taken, if applicable. All the nodes agree which node holds the example, by music goer. The node can request and release the lock.
This is just to say that computer science nerds make your online ticket to burning man possible.
The theme this year is robots, so check it out and get your nerd on.
