How To Share a Cake Over the Internet

I am not trying to troll here, but seriously, what? I read the headline several times, and then read the article summery, and all I can say is that I don't have a clue what this is talking about. I clicked on the first link, and it left me even more confused. This was the entire body of the first link:

We examine the history of cake cutting mechanisms and discuss the efficiency of their allocations. In the case of piecewise uniform preferences, we define a game that in the presence of strategic agents has equilibria that are not dominated by the allocations of any mechanism. We identify that the equilibria of this game coincide with the allocations of an existing cake cutting mechanism.

Cutting a cake is a game? I mean, at first I thought it was some sort of distributed computing post, but that doesn't really make sense either - why would distributed computing over the internet have this sort
