Computer fraud & hacking
In Hacker’s Delight, Henry Warren once again compiles an irresistible collection of programming hacks: timesaving techniques, algorithms, and tricks that help programmers build more elegant and efficient software, while also gaining deeper insights into their craft. Warren’s hacks are eminently practical, but they’re also intrinsically interesting, and sometimes unexpected, much like the solution to a great puzzle. They are, in a word, a delight to any programmer who is excited by the opportunity to improve.

Reviews for Hacker's Delight

This is the first book that promises to tell the deep, dark secrets of computer arithmetic, and it delivers in spades. It contains every trick I knew plus many, many more. A godsend for library developers, compiler writers, and lovers of elegant hacks, it deserves a spot on your shelf right next to Knuth. In the ten years since the first edition came out, it's been absolutely invaluable to my work at Sun and Google. I'm thrilled with all of the new material in the second edition. - Joshua Bloch When I first saw the title, I figured that the book must be either a cookbook for breaking into computers (unlikely) or some sort of compendium of little programming tricks. It's the latter, but it's thorough, almost encyclopedic, in its coverage. The second edition covers two new major topics and expands the overall collection with dozens of additional little tricks, including one that I put to use right away in a binary search algorithm: computing the average of two integers without risking overflow. This hacker is indeed delighted! - Guy Steele
