A collection useful programming advice the author has collected over the years; small algorithms that make the programmer's task easier. * At long last, proven short-cuts to mastering difficult aspects of computer programming * Learn to program at a more advanced level than is generally taught in schools and training courses, and much more advanced than can be learned through individual study/experience.

* An instant cult classic for programmers! Computer programmers are often referred to as hackers -- solitary problem solvers engrossed in a world of code as they seek elegant solutions to building better software. While many view these unique individuals as "madmen," the truth is that much of the computer programmer's job involves a healthy mix of arithmetic and logic. In Hacker's Delight, veteran programmer Hank Warren shares the collected wisdom -- namely tips and tricks -- from his considerable experience in the world of application development. The resulting work is an irresistible collection that will help even the most seasoned programmers better their craft. Henry S. Warren Jr. has had a 40-year career with IBM, spanning the computer field from the IBM 704 to PowerPC. He has worked on various military command and control systems, and on the SETL project under Jack Schwartz at NYU. Since 1973 he has been in IBM's Research Division at Yorktown Heights, New York. Here he has done compiler and computer architecture work on the 801 computer and its several variants through PowerPC. Presently he is working on the Blue Gene petaflop computer project. He received his Ph.D. in Computer Science from the Courant Institute at New York University in 1980.

Editorial Reviews

From the Back Cover

"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."

--Josh 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."

--Guy Steele

These are the timesaving techniques relished by computer hackers--those devoted and persistent code developers who seek elegant and efficient ways to build better software. The truth is that much of the computer programmer's job involves a healthy mix of arithmetic and logic. In Hacker's Delight , veteran programmer Hank Warren shares the tricks he has collected from his considerable experience in the worlds of application and system programming. Most of these techniques are eminently practical, but a few are included just because they are interesting and unexpected. The resulting work is an irresistible collection that will help even the most seasoned programmers better their craft.

Topics covered include:

A broad collection of useful programming tricks

Small algorithms for common tasks

Power-of-2 boundaries and bounds checking

Rearranging bits and bytes

Integer division and division by constants

Some elementary functions on integers

Gray code

Hilbert's space-filling curve

And even formulas for prime numbers!

This book is for anyone who wants to create efficient code. Hacker's Delight will help you learn to program at a higher level--well beyond what is generally taught in schools and training courses--and will advance you substantially further than is possible through ordinary self-study alone.
