Knuth Reward Check
This delightful anecdote recounts the author's personal triumph of finding a legendary error in one of Donald Knuth's meticulously reviewed books. It's a rare glimpse into the mythical world of Knuth's reward checks, a badge of honor in computer science. The story resonates with HN's audience for its deep dive into technical precision and the enduring legacy of a computing icon.
The Lowdown
Twenty years ago, the author achieved a feat many computer scientists only dream of: finding an error in a Donald Knuth book and receiving one of his famous reward checks. Knuth's reward system, where even typographical errors earn a payout, is legendary in the field, making this a truly unique accomplishment.
- The author discovered an error in Knuth's "Computer Modern Typefaces," Volume E in the Computers & Typesetting series.
- Against all odds, given the extensive review his books receive, the error was found on the very first page, in the first paragraph, within the first word.
- After rigorous re-checking, the author reported the bug and received a physical check for $1.20, a tangible piece of computer science folklore.
- The story highlights that Knuth now issues fantasy certificates from the "Bank of San Serriffe" instead of actual checks due to concerns over misuse.
- Years later, a second, smaller check for $0.32 was awarded for a 'throwaway sentence' in a bug report, despite the main error being incorrect.
This personal account underscores the meticulous nature of Knuth's work and the rare honor of being acknowledged for contributing to the perfection of his foundational texts.
