                Install MySQL 5.7 on macOS using Homebrew
              
          
This is a fork of original gist https://gist.github.com/nrollr/3f57fc15ded7dddddcc4e82fe137b58e, with slight changes on pointing to 5.7 version branch, instead of 8 (latest default of MySQL in Hombrew).

Install MySQL 5.7 on macOS

This procedure explains how to install MySQL using Homebrew on macOS (Sierra 10.12 and up)
Install Homebrew


Installing Homebrew is effortless, open Terminal and enter :

$  /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Note: Homebrew will download and install Command Line Tools for Xcode 8.0 as part of the installation process.


## heading.py
def wrap(angle):
    while angle > 2 * pi:
        angle -= 2 * pi
    while angle < 0:
        angle += 2 * pi
    return angle

def magnetometer_readings_to_tilt_compensated_heading(bx, by, bz, phi, theta, declinationRadians=0):
    """ Takes in raw magnetometer values, pitch and roll and turns it into a tilt-compensated heading value ranging from -pi to pi (everything in this function should be in radians).
        The correct value for declinationRadians can be found online: http://magnetic-declination.com/countries.php note that this value is in radians, not in degrees.
