Boolean

So, how much does /prog/ know about boolean logic?

I'll start you all off easy, what is the equivalent of
xor, eax eax?

(Don't give me shit about that being a machine code sample)

Boolean logic is easy.  Learn boolean algebra (you know, the kind of lattice).  It's also easy.

& = meet
| = join
~ = complement
0 = bottom
1 = top
