Stubble beard. Check. But sorry, I showered and shaved about 20 hours ago.
Esoteric code snob t-shirt? Sure, several.

Brings my own keyboard to work? Only real IBMs of course. And my last work (gone 2 years now) just gave the boy an old keyboard to bring home. They know he likes them. And he gave it to me. It was one of mine. I had left it there!
Cargo pants? How about painter's pants?
