Every day, patches are created to cover up security holes in software applications and operating systems. But by the time you download a patch, it could be too late. A hacker may have already taken advantage of the hole and wreaked havoc on your system. This innovative book will help you stay one step ahead. It gives you the tools to discover vulnerabilities in C-language-based software, exploit the vulnerabilities you find, and prevent new security holes from occurring.

CORDIC (Coordinate Rotation Digital Computer) is a method for computing elementary functions using minimal hardware such as shifts, adds/subs and compares. CORDIC works by rotating the coordinate system through constant angles until the angle is reduces to zero. The angle offsets are selected such that the operations on X and Y are only shifts and adds.

压缩解压算法LZ77算法有许多派生算法(这里面包括 LZSS算法)。它们的算法原理上基本都相同，无论是哪种派生算法，LZ77算法总会包含一个动态窗口（Sliding Window）和一个预读缓冲器（Read Ahead Buffer）。动态窗口是个历史缓冲器，它被用来存放输入流的前n个字节的有关信息。一个动态窗口的数据范围可以从 0K 到 64K，而LZSS算法使用了一个4K的动态窗口。预读缓冲器是与动态窗口相对应的，它被用来存放输入流的前n个字节，预读缓冲器的大小通常在0 – 258 之间。这个算法就是基于这些建立的。用下n个字节填充预读缓存器（这里的n是预读缓存器的大小）。在动态窗口中寻找与预读缓冲器中的最匹配的数据，如果匹配的数据长度大于最小匹配长度 （通常取决于编码器，以及动态窗口的大小，比如一个4K的动态窗口，它的最小匹配长度就是2），那么就输出一对〈长度（length），距离（distance）〉数组。长度(length)是匹配的数据长度，而距离(distance)说明了在输入流中向后多少字节这个匹配数据可以被找到。

This demonstration models a flight control for the longitudinal motion of a Grumman Aerospace F-14 Tomcat. First order linear approximations of the aircraft and actuator behavior are connected to an analog flight control design that uses the pilot s stick pitch command as the set point for the aircraft s pitch attitude and uses aircraft pitch angle and pitch rate to determine commands. A simplified Dryden wind gust model is incorporated to perturb the system.

This book explains how to write device drivers for the newest members of the MicrosoftWindows family of operating systems using the Windows Driver Model (WDM). In this Introduction, I ll explain who should be reading this book, the organization of the book, and how to use the book most effectively. You ll also find a note on errors and a section on other resources you can use to learn about driver programming. Looking ahead, Chapter 1 explains how the two main branches of the Windows family operate internally, what a WDM device driver is, and how it relates to the rest of Windows.
