Disable Homebrew auto-update every time you run it.md

Homebrew does something annoying and does its long update process almost every time you run it, which is irritating.

Here's a way to fix it while still keeping auto-updating on.

Add this to your .bashrc or equivalent:

HOMEBREW_NO_AUTO_UPDATE=1

Then, to keep your Homebrew updated, add this one-liner to your crontab (crontab -e):

@hourly if [ "`pmset -g batt | grep 'AC Power'`" != '' ]; then brew update > /dev/null 2> /dev/null; fi

This will run brew update hourly, but only if you're connected to AC power.
