这个库全称貌似为enhanced IO或者evented IO，用多线程实现了异步IO操作，为什么不用libev实现？因为libev用epoll，不支持regular file。没错，eio就是给fs模块用的。
从demo.c看如何使用：
翻开代码，有个demo.c，操作很多，常用文件io都包括了。精简一下代码，得到一个minidemo.c:
int respipe [2];
void
want_poll (void)
{
char dummy;
printf ("want_poll ()\n");
write (respipe [1], &a[......]
After peered the entry of Node.js, I think I have to read source code deeply in order to understand how does it working.
Beside the v8 engine, the most important is libuv. libuv as a platform layer for Node, its purpose is to abstract IOCP on Windows and libev on Unix systems. Of course, we pay a[......]
I wrote a classic tetris program just for touching the canvas component of HTML5.
Unfortunately, I have not run the javascript code by embedding into article successfully

Now we will read Init() which be called at first in Start()
Init(), as the name, is responsible for following work:
- Parse command line arguments
- Prepare v8 runtime
- Set v8 flags (like stack size limit)
- Set fatal error handler
- Prepare signal handler
- uv init
Node.js is not a single project as there are several components.
You can find them under NODEJS_SOURCE/deps:
http_parser, openssl, uv, v8, zlib
And of course, the source under NODEJS_SOURCE/src is the core of Node.js project. So I start to read the source code at this point. No matter whether i[......]
As well-known, binder driver is the core component of Android IPC mechanism. Either client side or service side use binder lib to complete the communication as usual. But we can also access binder driver directly. Here is an example, we open binder device and get version number var ioctl():

How to force the display of build commands:
——————————————-
Do “ndk-build V=1″ and actual build commands will be displayed. This can be used to verify that things are compiled as you expect them to, and check for bugs in the NDK build system.
(The V=1 trick comes f[......]

Android Recovery: 功能简介
Android支持Recovery模式。在某些操作之后，系统会自动重启并进入到Recovery模式，用户按组合键开机（HOME+POWER），也可进入Recovery模式。该模式提供如下功能：
1、擦除用户数据
恢复系统到出厂模式，即擦除用户数据和缓存数据。
2、系统升级
