GUID Combinations Comment Thread

How many GUID combinations are there? Generating GUID Trivia: "There are 122 random bits (128 - 2 for variant - 4 for version) so this calculates to 2^122 or 5,316,911,983,139,663,491,615,228,241,121,400,000 possible combinations" 40 comments: Anonymous said... What if I have 5,316,911,983,139,663,491,615,228,241,121,400,001 users? :)) said... then you define a user as being part of a domain with a domain guid. giving you 5,316,911,983,139,663,491,615,228,241,121,400,000 x 5,316,911,983,139,663,491,615,228,241,121,400,000 possible combinations. call me when you need more.

Then your users must be bacteria and should therefore switch to lnux.

A screenshot of an old technical discussion about the enormous number of possible GUID combinations. Commenters keep escalating the number of hypothetical users until the final punchline claims that such users must be bacteria and should switch to Linux. It is used as an absurd programmer reaction to impossibly large numbers or overengineered scalability questions.
