In Hacker's Delight Second Edition Hank 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. Extensive additions in this
edition include A new chapter on cyclic redundancy checking (CRC) including routines for the
commonly used CRC-32 code A new chapter on error correcting codes (ECC) including routines for
the Hamming code More coverage of integer division by constants including methods using only
shifts and adds Computing remainders without computing a quotient More coverage of population
count and counting leading zeros Array population count New algorithms for compress and expand
An LRU algorithm Floating-point to from integer conversions Approximate floating-point
reciprocal square root routine A gallery of graphs of discrete functions Now with exercises and
answers
