This is my backup script which syncs my server to my dropbox every day.

The script below is triggered every day from my Mac. I use Hazel to move the tar.gz to an external hard disk once it's finished. This happens every day without me noticing.

You should have a similar script.

Created September 12, 2013 00:21
When you've got a CLLocationCoordinate2D coordinate and want to plot a dot on a image of a map that you know its NW and SE coordinates. In my case the image is 100x100px.
CLLocationCoordinate2D sightingLocation = CLLocationCoordinate2DMake([self.sighting.locationLat floatValue], [self.sighting.locationLng floatValue]);
// Australia's map coordinates
CLLocationCoordinate2D nw, se;
nw = CLLocationCoordinate2DMake(-7.410849283839832, 112.41210912499992);
se = CLLocationCoordinate2DMake(-44.248667520681586, 154.07226537499992);
MKMapPoint topLeftPoint = MKMapPointForCoordinate(nw);
MKMapPoint bottomRightPoint = MKMapPointForCoordinate(se);
MKMapRect mapRect = MKMapRectMake(topLeftPoint.x, topLeftPoint.y, bottomRightPoint.x - topLeftPoint.x, bottomRightPoint.y - topLeftPoint.y);
