I'm glad someone caught the reference. Indeed, I took it from the [xchg rax,rax] book. Also, I have to apologize for the many bugs the demos have at the moment (annoying editor, missing features), I intended to post a Shown HN post at a later point in time. During the next days I will be taking care of these matters. By the way, these demos rely in Capstone.js/Keystone.js to assemble/disassemble machine code (if anyone is interested, similar demos can be found at https://phi.nz/ https://phi.nz/).
