Mac下同时安装多个版本的JDK

Mac自带了的JDK6，安装在目录：/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/下。

JDK7，JDK8则需要自己到Oracle官网下载安装对应的版本。自己安装的JDK默认路径为：/Library/Java/JavaVirtualMachines/jdk1.8.0.jdk

export JAVA_6_HOME=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

Add the following to your ~/.gitconfig file to show the git command output in color when working in a terminal

[color]
  ui = auto
[color "branch"]
  current = yellow reverse
 local = yellow

在Markdown格式的文章中合适的地方插入如下代码：

{% gist 743cdf8b26ceeef49fa1 %}

其中{% gist GIST_ID %}是固定格式，你只需找到实际的Gist ID代替GIST_ID。

因为一个Gist可以有几个文件，还可以只嵌入某个Gist中的某个文件，如下：

C:\Windows\System32>cd /d E:\images

E:\images>

	#import <Foundation/Foundation.h>

	@interface Person : NSObject

	+ (id)sharedInstance;

	@end

	angular.module('myApp', ['ngRoute'])
	.provider('Weather', function() {
	var apiKey = "";

	this.getUrl = function(type, ext) {
	return "http://api.wunderground.com/api/" +
	this.apiKey + "/" + type + "/q/" +
	ext + '.json';
	};
