While I was in the Bay Area last week I went browsing at Digital Guru bookstore in Sunnyvale, not far from where the old Computer Literacy used to be on Lawrence Expressway.
One of the books I found there was Hacker's Delight, a book very much in the spirit of the venerable MIT AI Labs memo HACKMEM.1 Whereas HACKMEM touches on mathematics, circuits and even cosmology2, Hacker's Delight pretty much sticks to (computer) mathematics.
The book has a nice website that goes along with it.
 Guy Steele's forward to the book also notes the resemblance.
 Check out Item 154, where Gosper proves that the Universe is two's-complement.
