On Math Overflow, I just saw an “answer” to a question, given by Scott Morrison, that I just had to share with anyone who hadn’t seen it. The Message of the Day, on Oct 2, at Berkeley was the following:
Warning: Due to a known bug, the default Linux document viewer
evince prints N*N copies of a PDF file when N copies requested.
As a workaround, use Adobe Reader acroread for printing multiple
copies of PDF documents, or use the fact that every natural number
is a sum of at most four squares.
