This Unix C code monitors a web server every few minutes by trying to retrieve its home page. It sends you email when it can t connect, and every so often while the server is still down. It sends a final message when it comes back up. If you have email paging, just direct the email to your pager address.-This Unix C code monitors a web server every few minutes by trying to retrieve its home page.

C 程序设计语言定义了两个标准的内存管理函数：malloc() 和 free()。C 程序员经常使用那些函数在运行时分配缓冲区，以便在函数之间传递数据。然而在许多场合下，您无法预先确定缓冲区所需的实际大小，这对于构造复杂的 C 程序来说，可能会导致几个根本性的问题。一种自我管理的抽象数据缓冲区概括地给出了抽象缓冲区的伪 C 代码实现，并详细介绍了采用这种机制的优点。-C programming language defines two standard memory management functions: malloc () and free (). C programmers frequently use those functions at run-time allocation of buffers in order to pass data between functions. However, in many occasions, you can not pre-determine the actual size of the buffer required, which for the complex structure of the C program, it may lead to several fundamental questions. A self-management, abstract data buffer generally gives the pseudo-C code for an abstract buffer implementation, and details the advantages of using this mechanism.

一套JSP CMS系统源码，前两年的成熟系统，现在重新发现了此源码，觉得对学习参考的价值还是有的，原先的名字叫 JeeCMS内容管理系统，可能JSP的内容管理系统用的人比较少，因此这些资料也是很难得的。编译注意：系统源码编译过程中需要额外的一些jar包，如果希望重新编译jeecms源码，需要用到common-lib文件夹下的jar包。

连续潮流：又称为延拓潮流，是电力系统电压稳定性分析的有力工具，它通过在常规潮流基础上引入一个负荷增长系数来克服雅可比矩阵奇异，从而克服接近稳定极限运行状态时的收敛问题，解决了常规潮流在崩溃点外无解和在崩溃点附近不能可靠收敛的问题。连续潮流法是从初始稳定工作点开始，随着负荷缓慢变化，沿相应的PV曲线对下一工作点进行预估、校正，直至勾勒出完整的PV曲线。(Continuous flow: also known as the continuation of the trend, is a powerful tool for voltage stability analysis of power system, by introducing a load growth coefficient to overcome Jacobi singular in the conventional power flow basis, so as to overcome the convergence problem near the stability limit of the running state, to solve the conventional power flow solution and in near collapse point reliable convergence problem in the collapse point. The continuation power flow method starts with the initial stable working point. With the slow load change, it predicts and corrections the next working point along the corresponding PV curve until the complete PV curve is outlined.)
