学网络高级编程不可多得的好书,讲得很详细(High school network programming rare books, very detailed)

多线程端口扫描演示，能够设置连接延时，使用Winsocket2 API编写，Delphi7编译通过-multithreaded port scanning demonstration connecting to delay, the use of API Winsocket2 prepared by compiling Delphi7

说明：  一个小型的DDE服务器，可以拿来练手和学习(A small DDE server that can be used for hands-on training and learning)

用perl写得一个完整的网络爬虫，支持内容过滤分类。支持很高的用户定义，搜索的结果可以存储到mysql或者zerba数据库，因为有完全的源码，对于学习和实用都很有价值。-a search engine system which combine with mysql or zerba database, suport content fliter.

网络通讯的源代码，是linux下libnet的win32移植，有一定参考作用。 由于本人没有仔细浏览贵站，不知道是否已有人上传-network communications source code is under linux libnet the win32 transfer, there are certain references. Because I did not carefully View Guizhan not know whether it has been uploaded

说明：  socket通讯 (发消息聊天) 实例源码 (亲测)(Socket communication (message chat) instance source code (pro test))

端口扫描java小程序 能够扫描端口并查看端口是否开启-Port scanning java applet to scan ports and see whether the port is open

说明：  传统的高分辨波达方向（DOA）估计算法中，一般都假设信号位于远场，此时入射到阵列的信源波前为平面波前，空间信号的定位参数可由DOA来确定。然而，当信源处于阵列的Fresnel区域时，信号波前需用球面波来描述，每个信源的定位信息要用DOA和距离联合描述。因此，远场情况下的一些线性理论推导已不再成立，传统的远场算法的估计不再适用(In traditional high resolution direction of arrival (DOA) estimation algorithms, it is generally assumed that the signal is located in the far field, where the source wavefront incident to the array is plane wavefront, and the location parameters of the spatial signal can be determined by DOA. However, when the source is in the Fresnel region of the array, the wavefront of the signal needs to be described by spherical wave, and the location information of each source needs to be described by DOA and distance. Therefore, some linear theoretical deductions are no longer valid in the far-field case, and the estimation of the traditional far-field algorithm is no longer applicable.)
