1 use python.el

There are plenty of python modes which support develop python in emacs, well, in my personal opinion, most of those are sucks, and Ffgallina's python.el is the much better one. 

Besides the major mode for python, I installed following python packages including rope, ropemode, Pymacs, and ropemacs.
Install rope, reopmode, and ropemacs were really easy with the help of python's package management tool pip. 

pip install rope 
pip install ropemode
pip install ropemacs
Pymacs provided the both-way communication between Emacs Lisp and Python, it can not installed by pip, so just download the source code from GitHub. 

Install pymacs python package first. 

make
sudo make install

Install emacs package pymacs.el which generated by above step. copy pymacs.el into the path which included in emacs's load-path. Then add the following line into init.el 

(require 'pymacs)

2 auto-completion in python.el

After I install packages, it can auto-complete python source code by key binding M-/. But what I wanna is to use the auto-complete package in python.el. 

There is some trouble when I wanna to enable auto-complete in python.el. auto-complete support python-mode default, what I need to do is add the following line to configuring file 

(ac-ropemacs-initialize)

But the newest auto-complete package is 1.3.1 which require yasnippt <= 0.6.0, while I installed the yasnippt 0.8.0. So, I disable yasnippt support in auto-complete. I need not downgrade yasnippt package in order to make auto-complete works. 

I upload the modified source code into Github. Now it still didn't support yasnippt.

How Bluetooth LE works? -- Link Layer

How Bluetooth LE works? - Link layer Table of Contents 1 Bluetooth LE system architecture 2 Bluetooth LE Physical layer 3 Bluetooth LE Link Layer states 4 Bluetooth LE Link Layer packets 1 Bluetooth LE system architecture This is the first post and hopefully a series of upcoming postings about Bluetooth Low Energy. Above figure is the protocol stack of a whole Bluetooth LE system. The Bluetooth LE is one part of Bluetooth v4.0 specification, it was designed not to pursue high transmission speed but for lower energy consumption. So the Bluetooth LE products can be powered by a button-cell battery for years. How did it do that? This article is a review of Robin Heydon's excellent book – Bluetooth Low Energy, the developer's handbook. Bluetooth LE is completely redesigned of classic Bluetooth protocol, It seems that both the Bluetooth LE and classic Bluetooth has the same architecture from above figure, but actually they are so different inside, an...

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...

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...
