Was wondering why the author sounded familiar. It's the XKCD comic author.

Yep. I first heard of his comics on /. when XKCD made a map of IPv4 [xkcd.com]. Pretty cool.

The first one is great. Hypotheticals that accidentally destroy the planet in the goofiest way, treated as seriously as possible. I love em
