使用Mercurial管理你的代码

 使用Mercurial管理你的代码
使用水银管理代码，首先它是分布式的管理系统，在这它用python开发，它跟git很相似，那么为什么还要mercurialn呢？难道git不好用吗？据说git只能在linux下工作，并且是linus花了两周时间写的。

1、Mercurial的使用
中文教程：http://mercurial.selenic.com/wiki/ChineseTutorial
最先用水银是用的google code提供的环境，由此可见google对python真是推崇的很哪！其实很简单跟svn的命令上区别不大。就是每次提交代码时都要输入用户密码之类的－麻烦（如何才能想svn那样认证一次就可以呢？）。
hg add filename
hg ci -m "description"
hg push
然后就提示认证信息了。

如何省去每次push认证的麻烦是修改.hg/hgrc文件
[path]
default = https://<username>:<password>@...../
2、hg跟svn的比较

见下面的链接：http://leeiio.me/googlecode-converting-svn-to-hg/
与集中式版本控制工具SVN不同的是，Hg是一种分布式版本控制工具。

3. 使用教程

    a. clone 克隆一份仓库到本地
    b. 使用hg log查看历史记录
        hg log -v (verbose) , -r1 (查看version 1), -p(显示跟特定的version的补丁文件)
    c. clone一份本地仓库
        hg clone repos1/ repos2/
    d. 对repos2做修改：
        hg status, revert, commit, diff, log
    e. 使用pull命令－本地仓库分享更改，然后使用update命令后才能修改本地文件。
    f. 不同机器上的仓库分享更改（import),当然是要用受到别人的补丁文件的(补丁文件使用export命令产生).
    g.  merge合并修改（如果两个仓库都做了修改，pull后要merge修改）

Bluedroid stack in android

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

How to setup an NAT server? Table of Contents What is NAT? How to setup NAT host? a shell script from vbird's book 1 What is NAT? 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
