Designing a book cover is harder than you might think. I was not designing a cover for an actual book, so I needed to come up with an enticing name, as well as make the name pop out. I decided to call the ‘book’ A 01010000 01100101 01110010 01110011 01101111 01101110 of Interest (the code is binary for ‘Person’). It has a hacker as the background surrounded by code, written by a former Russian operative, Volodva Sluchevsky.
