Cisco Security Bible 思科网络安全宝典 介绍基础原理、剖析网络安全体系结构，让你全面理解安全(Cisco Security Bible)

说明：  测量坐标正反算 1、已知A点的坐标及A点到B点的边长及方位角，计算B点的坐标。 2、已知A点和B点的坐标，计算A点到B的边长及方位角。(Forward and inverse calculation of measuring coordinates)

程序：实现Unix下通过Socket实现两台机器之间相互通信功能的示例。(: Unix through Socket two machines between communication capabilities of the examples.)

服务器，客户端聊天小程序，可能功能有点简单，但是原理都在(The server, the client chat applet)

说明：  本程序是window平台下，使用virtual C++编写文件下载程序，使用了Http协议(This program is a window platform, use the virtual C++ writing the file download process, using Http protocol)

务器端基于select I/O模型。为防止程序界面阻塞，有一个子线程用于不断接收socket并select其中的处理。客户端只有一个线程函数，不过其利用率很高，可用于远程目录交换，请求文件大小，创建若干线程来下载文件。文件传输有上传和下载,还有对等传输，这个项目中，传输文件具体指下载。 (side is based on the Treasury select I/O model. To prevent the program interface obstruction, a son threaded socket for receiving continuous and select which of treatment. Only one client thread function, but its high efficiency, long-distance directory can be used to exchange documents requested size, creating a number of threads to download files. Upload a file transfer and downloading, and the transmission of the project, specifically referring to transfer files downloaded.)

一个包含客户端、服务器的Corba实例，基于ACE和TAO(A CORBA Example Consisted of client and server)
