Last active August 29, 2015 13:56
Get the expected reading from the iPhone's compass when holding the phone in either landscape orientation.
- (void)locationManager:(CLLocationManager*)manager
didUpdateHeading:(CLHeading*)newHeading {
// If the accuracy is valid, process the event.
if (newHeading.headingAccuracy > 0) {
/**
* The orientation affects the compass. We need to actually
* base the orientation off of the top of the iPhone. Think
* of the direction the phone is facing when you hold it right

A set of best practices you can paste into your CSS to keep members on the same page.
/* KEEP OUR CSS CLEAN
Some guidelines to follow:
1. Break code down into sections. i.e. =BRANDING, =BODY, = WIDGETX, =WIDGETY, etc.
2. Keep your rules alphabetically sorted.
3. Only put one selector per line for a block of rules that apply to multiple selectors.
4. Indent your rules, only one rule per line.
example:
element#id,

jimjeffers / Easy Columns
Created February 26, 2009 21:30
Give any div a class 'column' and if it's absolutely positioned this jQuery script will fix the height of the container for you.
// Fix any absolutely positioned columns if necessary.
$(document).ready( function(){
$('.column').each(function(){
var cur = $(this);
if(cur.css('position') == 'absolute') {
var parent = $(cur.parent().get(0));
if(cur.height() > parent.height()) {
parent.css('height',cur.height());
}
}
