As we approach the end of the tour of my @github projects, there’s a little gem that I would like to show you in case you haven’t heard about it yet.

I’m referring to "xchg rax, rax" by xorpd, a short book of x86-64 #assembly #poems and #riddles. You read that right; as it turns out, assembly is not only for #shellcoding 😉

Some years ago, I tried to tackle those riddles, and here’s the result:

I’m much older and wiser now and I should probably give another try to the riddles that still remain unsolved. Or perhaps it’s a job for you, dear reader.
