作者在二十年前发现了计算机科学家Donald Knuth的著作《Computer Modern Typefaces》中的一处错误，该错误位于该书第1页第一段的第一个单词1。这一发现使其获得了Knuth著名的勘误奖励支票1。
奖励支票总额为$3.20，其中包括$2.88（按高德纳特殊标记方式表示为0x$1.20）和$0.32两部分1。作者随后因在bug报告中提出的一句话被Knuth视为有效建议，又获得了第二张支票1。值得注意的是，Knuth目前已不再签发真实支票作为勘误奖励，而是改为颁发来自虚拟银行"San Serriffe银行"的证书1。
A contributor to Donald Knuth's work discovered an error in Computer Modern Typefaces and received one of the legendary computer scientist's famously modest reward checks.1 The mistake appeared on page 1 of the book, in the first word of the opening paragraph.1 Twenty years after identifying the error, the author shared the experience of claiming Knuth's celebrated bounty system.1
The initial check amounted to $2.88, composed of a hexadecimal $1.20 plus $0.32.1 The author subsequently received a second check after Knuth credited a suggestion derived from the contributor's bug report as a valid improvement.1 Over time, Knuth has shifted his approach to these rewards; he no longer issues physical checks but instead presents certificates from a fictional institution, the "San Serriffe Bank," to acknowledge errors and suggestions in his published works.1
