-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.

访问about:config

把javascript.enabled设置为false.

这样就可以直接复制一些需要登录才能复制的网页上的内容了（比如360doc）。
