1、 了解系統調用pipe()的功能和實際原理 2、 編寫一段程序,使用管道實現父子進程之間的通信 a) 使用系統調用fork()創建一個子進程 b) 子進程調用函數write()向父進程發送自己的進程ID和字符串” s sending a message to parent.\n”。 c) 父進程調用函數read()通過管道讀出子進程發來的消息,將消息輸出屏幕,然后終止

This book is the most accurate and up-to-date source of information the STL currently available. ... It has an approach and appeal of its own: it explains techniques for building data structures and algorithms on top of the STL, and in this way appreciates the STL for what it is - a framework. Angelika Langer, Independent Consultant and C++ Report Columnist "A superbly authored treatment of the STL......an excellent book which belongs in any serious C++ developer s library." Jim Armstrong, President 2112 F/X, Texas. \n The C++ Standard Template Library (STL) represents a breakthrough in C++ programming techniques. With it, software developers can achieve vast improvements in the reliability of their software, and increase their own productivity.

長高44b0xi BIOS源碼 FS44B0II BIOS具有啟動、引導,下載、燒寫,設置日期、時間,設置工作頻率等多種功能,並且支持各種參數的存儲和自動調用。 可以用flashpgm等軟件將BIOS燒寫到Flash中去,BIOS的自身駐留地址位于NOR FLASH的0x1f0000處,系統參數保存在0x1ff000以上區域中。所以在燒寫完BIOS,上電復位后先要執一定要執行backup命令把BIOS本身拷貝到NOR FLASH的高端1f0000去。

我用matlab寫的一個corner detector, 效果比現在流行的harris,susan,CSS等效果要好。 Algorithm is derived from: X.C. He and N.H.C. Yung, Curvature Scale Space Corner Detector with Adaptive Threshold and Dynamic Region of Support , Proceedings of the 17th International Conference on Pattern Recognition, 2:791-794, August 2004. Improved algorithm has been included in A Corner Detector based on Global and Local Curvature Properties and submitted to Optical Engineering.

RSA ( Rivest Shamir Adleman )is crypthograph system that used to give a secret information and digital signature . Its security based on Integer Factorization Problem (IFP). RSA uses an asymetric key. RSA was created by Rivest, Shamir, and Adleman in 1977. Every user have a pair of key, public key and private key. Public key (e) . You may choose any number for e with these requirements, 1< e <Æ (n), where Æ (n)= (p-1) (q-1) ( p and q are first-rate), gcd (e,Æ (n))=1 (gcd= greatest common divisor). Private key (d). d=(1/e) mod(Æ (n)) Encyption (C) . C=Mª mod(n), a = e (public key), n=pq Descryption (D) . D=C° mod(n), o = d (private key
