    Donald Knuth – TAOCP & TeX.

    You need to point out mistakes in TAOCP to get a check like that – 256 pennies is 1 Hexadecimal Dollar is the logic behind the $2.56 amount.

  10. one of my all time favorite fundas..
    that is a cheque that donald knuth gives if you can mail him with a correction to something in the art of programming books.. he strangely (considering its him.. not quite strange though) believes in counting in the hexadecimal system.. so 2.56 dollars in base 10 gives you 1 dollar in base 16.. i wonder if anyone actually cashed that cheque..
