find the smallest distance between two angles
// from http://stackoverflow.com/a/7869457

// x and y are the angles in radians
function getDifference(x, y) {
var a = x-y;
a = (function(i, j) {return i-Math.floor(i/j)*j})(a+Math.PI, Math.PI*2); // (a+180) % 360; this ensures the correct sign
a -= Math.PI;

Resize Arch Linux display

Look for the name in your display (e.g. VGA-1) and possible resolutions (e.g. 1280x768) in

xrandr -q | head

And resize your display like so:

xrandr --display :0 --output NAME_OF_YOUR_DISPLAY --mode WIDTHxHEIGHT
