pocorgtfo is pretty good, but it's more aimed at 'weird machines' than just exploit techniques. You can also buy a copy online that comes looking like a bible, which I rather cherish as a possession ;)
I feel a little uneasy reading them in public, though. The cover has, in big, bold beautiful letters "PoC || GTFO" which might lead someone who isn't familiar with the binary OR operator and the use of PoC as "Proof of Concept" to believe I hold opinions that I VERY much don't.
