8queen
在一个8×8国际象棋盘上，有8个皇后，每个皇后占一格；要求皇后间不会出现相互"攻击"的现象,即不能有两个皇后处在同一行、同一列或同一对角线上。问共有多少种不同的方法。
本算法采用一维数组来进行处理。数组的下标i表示棋盘上的第i列，a[i]的值表示皇后在第i列所放的位置。如：a[1]=5，表示在棋盘的第一例的第五行放一个皇后。(8 × 8 in a chess set, there s eight, each accounting for a Queen s grid request will not be any mutual between Queen s attack phenomenon, that can not have two Queen s in the same line, the same row or the same diagonal. Asked the total number of different ways. This algorithm uses one-dimensional array to be processed. Array subscript i said i chessboard first out, a [i] value that s in the first place i listed by location. Such as: a [1] = 5, said the first cases in the chessboard of the fifth line of a Queen s release.)

PNEV512B_-_LPC1227_NDEFmsg
1. Document purpose
This document describes the content of the source package as well as known
problems and restrictions.
A separate User Manual describes the first steps how to use the software in
combination with the Hardware.
2. Known problems and restrictions
* Restrictions
The Software is restricted to the Hardware, described in the attached
schematics. The API is intended for the NXP contactless/contact reader ICs,
as such the API is not to be ported to any technology from any other vendor.
The Software is running on a Cortex M0 LPC1227/301 controller from NXP.
NXP will not support porting to any other vendor platform.
The Hardware will go through an CE certification, as such there may be
future versions of this Hardware which will have small adaptations in the
schematics. Nevertheless the software is designed in a way to support also
the future variants. The Software stack was validated according to CE.(1. Document purpose This document describes the content of the source package as well as known problems and restrictions.

网络流量监控
为了方便网络编程，90年代初，由Microsoft联合了其他几家公司共同制定了一套WINDOWS下的网络编程接口，即Windows Sockets规范，它不是一种网络协议,而是一套开放的、支持多种协议的Windows下的网络编程接口。本篇论文主要是介绍了在TCP/IP基础上利用winsock2对网卡进行编程，以达到网络流量监测的目的。论文首先介绍了TCP/IP协议，旨在介绍IP，TCP，UDP等比较重要的协议。主要是介绍IP头，TCP头，UDP头的特点，以便从IP头中可以获取源地址，目的地址，协议类型等信息。在随后的章节中提出了Socket的概念，Socket实际上提供了一个通信端口使所有拥有Socket的端口的计算机之间能够相互通信，在本论文中主要说明了socket的建立，监听和撤销的过程。具体到程序实现中，对网卡混杂模式的设置是通过原始套接字（raw socket）来实现的。为了让原始套接字能接受所有的数据，还需要通过将SOCK_RAW设置成SIO_RCVALL。对数据包的获取通过recv()函数来完成。最后要完成的工作就是对所捕获的IP数据包进行分析以提取出我们所需要的信息。在论文的最后是旨在说明进一步工作的展开。
