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

读后感
相比的学校里acm的曲高和寡,这本书是最接工作应用地气了，到了“吹毛求疵”“令人发指”，“原子核”的地步了。 联想到三国武将值加点.我决定学习关二哥，不是专业的就把他作为春秋，平时读读索引在印象里，该用时拿出春秋来摆造型。

有点像加德纳写的数学科普文章，各种计算（偏底层）的奇技淫巧。搞算法优化和编译器的童稚可以看看。
