qemu cpu模拟器

前段时间，看到有qemu这个东西，可以模拟cpu，来启动自己设定或修改的内核，不过听说他还是个虚拟机，可以用来安装其他的系统的。
我用它来启动的suse的内核，果然可以，就是内核启动后，可用的命令有限，不知道怎样关掉。不过仍然很兴奋，以后可以自己随便编译内核的参数，用它来测试就可以了。
1。建立虚拟的硬盘，qemu-img create linux.img 1G
2。启动内核 qemu -kernel vmlinuzfile -initrd initrd-file linux.img
使用ctrl-alt-f 可以在全屏之间转换的。

Bluedroid stack in android Table of Contents Bluetooth stack in android Bluedroid .VS. Bluez Porting guide of Bluedroid stack 1 Bluetooth stack in android From Android 4.2, google use Bluedroid stack as its default Bluetooth host stack, before android 4.2, its default Bluetooth host stack was Bluez, which is also the Linux distribution's default stack. So why google changed its Bluetooth stack? The reason is maybe that Bluez stack was designed for the desktop environment, so in order to port Bluez into android, android must solve some dependency issues, like porting Dbus, Linux desktop's default IPC, into android. So there are at least five processes to power Bluetooth before android 4.2, they are systems, Bluetooth APP, Bluez, hciattach, and Dbus. The damn thing is that there are bugs between them, so Bluetooth stack is the weakest part in the android system before android 4.2, yeah, it is the usual reason that android system corrupted. So, what's t

NAT stands for Network Address Transition, which is the basic function of gateway host. I try to hack Bluetooth tethering module in android this week, it include the Bluetooth Pan profile and the NAT setup process, which means in order to implement the Bluetooth tethering, first, two devices must be connected by Bluetooth Pan profile, and then the server part device acted as gateway host to supply the network forward service. In other words, after Bluetooth Pan profile connected, the server must to setup its NAT rules to forward the IP packages. So how to setup NAT rules? 2 How to setup NAT host? My memory is still fresh that at the start of my Linux journey, I setup my Linux desktop as an NAT host to provide Internet services for my lab's classmates. During the days as a programmer, I once did a job to hacking android&

Network programming in elisp

  Network API in elisp Table of Contents 1 Introduction 2 A example 3 Http server implemented by elisp 1 Introduction Emacs is not just an editor, Yes, that's true. Emacs lisp can do network connection programming by its network API. But there is something difference with other kinds of programming language. First, elisp do not support multi-thread, pretty cool, huh!! Yeh, Multi-threads programming is a horrible venture for you, right! Second, There is no socket similarly conception in elisp, and elisp provide network programming ability as processes. Elisp can open a network connection by function – open-network-stream .  It can make network connection server listen a special port by function - make-network-process . Both of those function return a process object. Then you can communicate with the process by process's API. 2 A example I write a snippet code to figure out How to use it. ( require ' cl ) ( defvar my-network-client-b
