该程序实现了服务器和客户机之间的交互和通信，对于网络编程学习很有帮助-the process of server and client and the interaction between communication, network programming useful learning

VC++实现类似于QQ文件传输功能的文件发送与接收程序示例，分为服务端和客户端，客户端首次接收数据，将判断文件包大小，数据包中一定包含完整的数据包结构信息，数据不一定完整；读取数据包的大小，包含数据包结构大小和数据大小，之前接收的数据与现在接收的数据能够构成至少一个完整的数据包，文件接收完毕则设置结束标记，若终止的连接，则弹出窗口告诉用户，对方终止了文件传送。 　　服务端程序是比较简单的，基本是复制文件数据、判断文件是否传递成功、等待对方收受发送任务或取消发送任务，分包继续发送文件等功能(VC++ implementation is similar to QQ file transfer capabilities to send and receive files program examples, divided into server and client, the client receives the first data packet to determine the file size, the packet must contain the complete information packet structure, the data is not must complete reading packet size, including the size and structure of the data packet size, and previously received data received data can now constitute at least one complete packet, the file has been received then set the mark, if the connection is terminated, the pop-up window telling the user, the other party to terminate the file transfer. Server program is relatively simple, basically copying the file data, to determine whether the file transfer is successful, waiting for the other to accept or cancel the sending task sends tasks, subcontractors continue to send files and other functions )

acl_cpp 是基于 acl 库的 C++ 库，包括 MIIME 解析、Handlersocket 客户端库、数据库连接池（支持mysql/sqlite）、WEB 编程、数据库编程、阻塞/非阻塞数据流等内容。(acl_cpp is based acl library of C++ libraries, main elements: common features acl C library, MIIME parsing, Memcached client library, Handlersocket client library, connection pool (support mysql/sqlite), WEB programming, programming, blocking/non-blocking streams and other content.)

求一段音频信号的短时过零率，可用于特征的选取，以及对音频进行分类筛选等场合。(For the sound process)

Currently, most of people use MS DCOM/COM+, Java Bean/RMI, and Corba to do distributed computing over internet. All of these technologies are provided with some tools and intermediate objects to simplify internet development. However, these technologies have one common and fundamental problem that all of the calls between a client and a server are blocked for a returned result (please correct me if this is wrong). A client stays still, and has to wait for a while after sending a request to a server. If the request is a lengthy action, the client application seems to be dead to a user. In most cases, we could use a worker thread at the client side to do background computation for solving this problem. However, this comes with an expensive price, more coding, data synchronization and mess in coding logic. Additionally, I also doubt that these technologies are able to really move data across internet efficiently.
