Knuth reward test

It’s been twenty years now that I’ve gotten among the finest letters ever. Donald Knuth confirmed the error I had present in one in all his books and despatched me the coveted check!

Donald Knuth and his reward for any error in one in all his books (even typographical ones) are laptop science folklore. Preposterous to assume that I might probably earn one! His books have been combed by means of by 1000’s and 1000’s of individuals. Smarter folks than I’m. More affected person folks.

And then it occurred. I assumed I had discovered an error. But I didn’t report it immediately, I waited and re-checked it for months, lest I make a idiot of myself. I even instructed our native genius at college who didn’t care a lot and dismissed my pleasure.

See, the error I discovered is in a really particular place. The guide is “Computer Modern Typefaces”, so it’s a much less learn guide (not the TeXbook or The Art of Computer Programmming), however nonetheless, virtually everyone who has provided that guide a shot may have learn over that error.

Because it’s on web page Arabic one. In the primary paragraph. The very first phrase.

That’s why the Memo area says “E1”: Computer Modern Typefaces is Volume E within the Computers & Typesetting collection. Page 1.

I’ve censored the test barely, as a result of Knuth is afraid somebody may do dangerous issues with these numbers, and he hasn’t been handing out actual checks for a few years now. Today you get a fantasy certificates of a fantasy financial institution, the Bank of San Serriffe.

But why will you discover me there with the entry “0x$1.20”, i.e. decimal $2.88? Just a few years later I despatched in one other proposed error, however I used to be improper. Knuth really wrote a number of paragraphs why precisely I’m improper, however as a result of he counted some throwaway sentence in my bug report as suggestion, I acquired one other test for $0.32.
