自己编写一个操作系统，是许多程序员的梦想。也许有人曾经挑战过，但因为太难而放弃了。其实你错了，你的失败并不是因为编写操作系统太难，而是因为没有人告诉你那其实是一件很简单的事。那么，你想不想再挑战一次呢？ 这是一本兼具趣味性、实用性与学习性的书籍。作者从计算机的构造、汇编语言、C语言开始解说，让你在实践中掌握算法。在这本书的指导下，从零编写所有代码，30天后就可以制作出一个具有窗口系统的32位多任务操作系统。 本书以课题为主导，边做边玩，抛开晦涩难懂的语言，行文风格十分随性，还充满了各种欢乐的吐槽，适合操作系统爱好者和程序设计人员阅读。

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
