Installing Python 3.6 on Raspbian

As of January 2018, Raspbian does not yet include the latest Python release, Python 3.6. This means we will have to build it ourselves, and here is how to do it. There is also an ansible role attached that automates it all for you.

Install the required build-tools (some might already be installed on your system).

在vimrc文件中，添加以下代码，然后重启vim，即可实现按tab键产生4个空格：

set ts=4  " ts是tabstop的缩写，设TAB宽4个空格
set expandtab

对于已保存的文件，可以使用如下方法进行空格和TAB的替换：

TAB替换成空格

	#include <iostream>
	using namespace std;

	struct Point {
	double m_x;
	double m_y;
	};


	bool pointInPolygon( Point point, Point* vs, int length )

	http {
	// ssl 相关配置 ...

	map $http_upgrade $connection_upgrade {
	default upgrade;
	'' close;
	}

	server {
	listen 8020;

	#! /bin/bash
	wget https://github.com/google/protobuf/releases/download/v2.6.1/protobuf-2.6.1.tar.gz
	tar xzf protobuf-2.6.1.tar.gz
	cd protobuf-2.6.1
	sudo apt-get update
	sudo apt-get install build-essential
	sudo ./configure
	sudo make
	sudo make check
	sudo make install

	defmodule Constants do
	@moduledoc """
	An alternative to use @constant_name value approach to defined reusable
	constants in elixir.

	This module offers an approach to define these in a
	module that can be shared with other modules. They are implemented with
	macros so they can be used in guards and matches

	## Examples:

	[mysqld]

	# GENERAL #
	user = mysql
	default-storage-engine = InnoDB
	socket = /var/lib/mysql/mysql.sock
	pid-file = /var/lib/mysql/mysql.pid

	# MyISAM #
	key-buffer-size = 32M

-# delete local tag '12345'
-git tag -d 12345
-# delete remote tag '12345' (eg, GitHub version too)
-git push origin :refs/tags/12345
-# alternative approach
-git push --delete origin tagName
-git tag -d tagName
