Geekos 全部project，基于Geekos的操作系统设计与实现(all the geekos project)

说明：  操作系统银行家算法，C#编写，比较漂亮，有用！(OS Banker' s algorithm, C# prepared, more beautiful, works!)

JOS LAB1 试验报告,操作系统实习mit.6.828(JOS LAB1 Test Report)

这个程序是模拟采用二级目录结构的磁盘文件系统中的文件操作，它可以实现对文件的一些基本管理，如：读、写、删除文件等。通过这个程序可掌握文件子系统的原理，加深对二级目录结构的文件系统中用户管理、文件管理、目录管理的理解，并用程序实现对文件子系统的模拟。(the procedure is simulated using two disk directory structure of the file system file manipulation, it can be achieved on some basic document management, such as : read, write, delete files. Through this procedure can grasp the principle document subsystems to enhance the structure of the two file system user management, document management, directory management, understanding, and the procedures to achieve the right documents subsystem simulation.)

这本书是专门为黑客基本的分析程序使用调试器和汇编器的方法。这是有问题的巨大兴趣，但在现实中，很少有对谁掌握了专业水平，这些方法的程序员。(This book is dedicated to the basics of hacking—methods of analyzing programs using a debugger and disassembler. There is huge interest in this topic, but in reality, there are very few programmers who have mastered these methods on a professional level. )

用纯C语言编写的一个Linux下的Shell，包含tch和bash的基本功能（包含重定向和后台运行），暂时不支持管道。已经在cygwin和Ubantu 7.10下测试通过。 主要包含： makefile 编译生成myshell可执行文件 myshell.c 主函数（涉及程序入口） utility.c 所有功能函数（将近1000行） myshell.h（包含宏定义、结构体声明、库函数的头文件，及utility.c中的所有函数的声明） readme 用户手册（当用户在myshell里输入help <command> 时，输出<command>的使用说明） (With pure C language under Linux in a Shell, contains tch and bash the basic functions (including redirect and running in the background), the moment does not support the pipeline. Has been under cygwin and test Ubantu 7.10. Mainly includes: makefile compiler generated executable file myshell main function myshell.c (relating to procedures for entrance) utility.c all the features of function (nearly 1000 lines) myshell.h (contains macro definition, the structure declaration, the first document library, and all utility.c statement function) readme user' s manual (when users enter help in myshell <command> , The output <command> The use of explanation))

说明：  这是个一个基于mips的开源操作系统ucore.(An operating system based-on mips.)

C implementation of the readers writers problem !

操作系统定时刷新功能，利用TIMER定时器定时后调用系统刷新功能，可做到计算机自动刷新、开机启动，并可设置刷新间隔时间并存档。(Operating system timing refresh function, using TIMER timer to call system refresh function after timing, can automatically refresh the computer, start, and set refresh interval time and archive.)

基于EOS方法位移约束拓扑优化，可以有效的得到最优的结构。(Based on the EOS method, the optimal structure of the displacement constrained topology can be obtained effectively.)
