代码说明:

基于邻域的算法是推荐系统中最基本的算法,该算法不仅在学术界得到了深入的研究,而且在工业界也有广泛的应用。基于邻域的算法分为两大类,一类是基于用户的协同过滤算法,另一类是基于物品的协同过滤算法。这里只介绍一种基于用户的协同过滤算法。 在一个在线个性化推荐系统中,当一个用户A需要个性化推荐时,可以先找到和他有相似兴趣的其他用户,然后把那些用户喜欢的、而用户A没有听说过的物品推荐给A。这种方法称为 基于用户的协同过滤算法 。

    A new method of propagation for computer viruses is here presented, Automated File Transfer Infection (AFTI). This method is specific for the Microsoft® Windows® NT/2000/XP/Server 2003 platforms, albeit it may be extended to the 95/98/ME systems as well, and even other Operating Systems. It is based upon WinSock 2 hooking with the Service Provider Interface (SPI).(A new method of propagation for computer vi ruses is here presented. Automated File Transfer Infection (AFTI).

  • STM32-USART-send-and-receive-data-
    本程序目的是提供使用stm32串口收发一帧数据的一种方法,采用中断方式接受和发送,每进一次中断接收或发送一字节,可以实现pc机与板子通信或板子与板子间通信。注意本程序中外接高速晶振为12M赫兹,而大部分板子为8M赫兹,本程序所用芯片是stm32RBT6(The purpose of this procedure is to provide a method of using STM32 serial port to send and receive a data, using interrupt mode to receive and send, every one into the time interrupt receiving or sending a byte, can realize PC and the communication or board and board communication. Note that this procedure the external high-speed crystal oscillator for the 12M Hz, while the majority of board is 8M Hz, the chip used in this procedure is stm32RBT6)
