I found a bug in Algorithm D, the long division algorithm in Knuth's "The Art of Computer Programming". It was discussed on HN a couple of times https://news.ycombinator.com/item?id=26562819 as well as on other websites.
I sent a letter to Knuth and received a check and an annotated reply. The updated Theorem B, which was unchanged since 1969 is now dated 2026.
While searching for vulnerable implementations I also found a "bug" in llvm, so I expanded a bit on that too.

Congratulations! Wow, you got a legendary $2.56 check....

Hopefully framed it and put it on the wall.

Unfortunately, one no longer gets physical checks, instead, one gets an account in The Bank of the Island of San Seriffe:
