自己编写的类似画图软件的vc++程序，可以实现铅笔画线、画圆、椭圆等基本画图功能，还有颜色选项(I have written similar vc++ drawing software program, you can achieve a pencil drawing a line, circle, ellipse and other basic drawing functions, as well as color options)

说明：  用C++实现了一个飞机大战的游戏，游戏中有敌方飞机，用C++类来实现，地方飞机有大中小飞机，用C++的继承来是实现，是个不错的C++基础项目(A game of aircraft war is realized with C++. There are enemy planes in the game, which are implemented with C++ classes. Local planes have large, medium and small planes. It is a good basic project of C++ that is realized with the inheritance of C++)

说明：  TAB控件的应用，在TAB控件的各选项卡里分别嵌入了列表控件、按钮控件以及下拉列表控件，并对列表控件进行了初始化，对初学者很有帮助。(In the application of tab control, list control, button control and drop-down list control are embedded in each tab of tab control, and the list control is initialized, which is very helpful for beginners.)

PT2314，音频通道4选1输出，有重低音、mute功能。(PT2314, audio channel 4 to 1 output, heavy bass, mute function.)

疯狂iOS讲义6-9章讲义, 主要是多线程和网络编程部分的内容(crazy iOS 6-9chpter)

说明：  osgEarth的地形分页流程，我大致的写一下，感兴趣的话，大家可以去代码中看看，以MPEngine为例(osg tile TilePagedLOD* plod = new TilePagedLOD( _engineUID, _liveTiles, _deadTiles ); plod->setCenter ( bs.center() ); plod->addChild ( tileNode ); plod->setFileName( 1, Stringify() getKey().str()

Ucore是一个很小的适于学习的操作系统，此“麻雀”包含虚存管理、进程管理、处理器调度、同步互斥、进程间通信、文件系统等主要内核功能，总的内核代码量（C+asm）不会超过5K行。充分体现了“小而全”的指导思想。 这是ucore的实验1：系统软件启动过程。实验目的：操作系统是一个软件，也需要通过某种机制加载并运行它。在这里我们将通过另外一个更加简单的软件-bootloader 来完成这些工作。为此，我们需要完成一个能够切换到x86 的保护模式并显示字符的bootloader，为将来启动操作系统做准备。proj1 提供了一个非常小的bootloader，整个bootloader 的大小小于512 个字节，这样才能放到硬盘的主引导扇区中。通过分析和实现这个bootloader，读者可以了解到：基于分段机制的存储管理、设备管理的基本概念、PC 启动bootloader 的过程、bootloader 的文件组成、编译运行bootloader 的过程、调试bootloader 的方法、在汇编级了解栈的结构和处理过程、中断处理机制、通过串口/并口/CGA 输出字符的方法。文件中包括源代码、实验指导书和实验报告。(Ucore is a small operating system for learning, the " Sparrow" contains the virtual memory management, process management, processor scheduling, synchronization mutually exclusive, inter-process communication, file system and other major kernel functions, the total amount of kernel code ( C+ asm) no more than 5K lines. Fully embodies the " small" the guiding ideology. This is ucore experiment 1: the system software boot process. Purpose: the operating system is a software, but also need some mechanism to load and run it. Here we will adopt another more simple software-bootloader to complete these tasks. To this end, we need to be able to complete a switch to the x86 protected mode and display the characters bootloader, the operating system to start to prepare for the future. proj1 provides a very small bootloader, the bootloader is less than 512 bytes in size, so as to put the hard disk master boot sector. Through the analysis and to achieve this bootloader, the read)
