Knuth reward check
Points and comments are a snapshot, not live.
A reader recounts finding an error on page 1 of Knuth's Computer Modern Typefaces and receiving a reward check.
The author found a typographical error in Donald Knuth's book "Computer Modern Typefaces" (Volume E) on page 1, the first word. After months of verification, he reported it and received a check for $2.88 (0x$1.20). A later, incorrect suggestion earned $0.32. Knuth now issues fantasy certificates from the Bank of San Serriffe due to fraud concerns.
What commenters are saying
Commenters shared personal experiences of receiving Knuth reward checks, with several claiming multiple. A correction noted that Alan Turing didn't break the Enigma alone; Polish cryptanalyst Marian Rejewski did. Technical discussion covered the finite parameter space of the claimed "infinitely many alphabets." Some lamented the era's end, noting AI-assisted bug reports are increasing.
