-d      Create an assertion to prevent the display from sleeping.
-i      Create an assertion to prevent the system from idle sleeping.
-m      Create an assertion to prevent the disk from idle sleeping.
-s      Create an assertion to prevent the system from sleeping. This assertion is valid only when system is running on AC power.
-u      Create an assertion to declare that user is active. If the display is off, this option turns the display on and prevents the display from going
        into idle sleep. If a timeout is not specified with '-t' option, then this assertion is taken with a default of 5 second timeout.

$ pip install pyopenssl --trusted-host pypi.python.org
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting pyopenssl
  Could not fetch URL https://pypi.python.org/simple/pyopenssl/: There was a problem confirming the ssl certificate: Can't connect to HTTPS URL because the SSL module is not available. - skipping
  Could not find a version that satisfies the requirement pyopenssl (from versions: )
No matching distribution found for pyopenssl

From Python Developer’s Guide

As of OS X 10.11, Apple no longer provides header files for the deprecated system version of OpenSSL which means that you will not be able to build the _ssl extension.

最近被迫写文档，把用word写的本地文档搬到线上去，一堆图片要加，在此记一下osx批量无损导出图片的方法

方法一：

把word保存成网页，在文件夹里面找（都是gif质量有下降）

方法二：

保存成docx,然后用the unarchiver打开， 找到media文件夹，png，jpg都在里面

期末了还在搬砖，怕一闲下来就太想rena啊orz

前言

在HKU实验室搬砖，这边的网络和mac绑定的，调试linux服务器只能用一台局域网里的垃圾windows8.1，实在是太annoying，果断改mac上mac。

过程

本想用ifconfig直接修改mac地址，

$ ipconfig en0 down
$ sudo ipconfig en0 ether xx:xx:xx:xx:xx

结果收到提示ifconfig: ioctl (SIOCAIFADDR): Device power is off
查了一下osx 10.7还是多少以上不能用ifconfig这样改，所幸发现了SpoofMac，装了可以轻轻松松修改en0了不过…
