I've never seen a software project choose a Ypsilon in their name before. Have any examples?

μ provides a good contextual clue about the project. What would the ε character tell me?

That's epsilon, not ypsilon (it just occurred to me that it's more common to see it called "upsilon" in English, though I don't know why based on how the letter is pronounced - "eee-psilon")

Oooh! Thank you for pointing that out

Smaller than μ. Still strictly positive but as small as you want. Nothing possibly smaller.

Except maybe the surreal numbers ? https://en.wikipedia.org/wiki/Surreal_number those are smaller than "as small as you want" :P

Damn! Let's be real though.
