Let's see if GUIDs are really *that* hard to guess.
>The number of possible GUIDs (128-bit value) is 2^(128) or 3.4×10^(38) — roughly 2 trillion per cubic millimeter of the entire volume of the Earth.
I built a website where every visit and guess puts a random GUID into the database. Your job is to try and guess one. The more GUIDs there are, the easier to guess one, but we will probably never guess a single GUID. #entertainment
