A good friend of mine, Robert Curtis, has advanced me more in my technical knowledge than any book, school, or previous job. Whether from his patient teachings or his vast amount of well documented open source projects, I've become a far better engineer and owe many of my personal technical achievements to Rob.One of his most recent projects, I've had the pleasure of being able to contribute to, although only a small amount thus far.Rob, using core location, put together a great little program that does one thing very well, keeps tabs on your Apple Computer. Built in Apple's SDK, is an API called core location. Simply put, it is a common interface to obtain your location on any apple platform where the underlying platform knows independently whether you have GPS, Wifi, or Ethernet.ETPH stands for E.T. Phone Home. ETPH runs as background service on your mac and will calculate your location at any interval you specify. If successful, it will send your location to the included php file residing on any server of your choice with standard HTML, no need to setup port forwarding or have any additional device running on your server. However, you always have the option of using htpassword [link] to password protect your map and your php file. Using php, I created another file called map.php. The purpose of this file is to grab the last logged location and draw the google map. It also displays the last 30 locations in the etph.log file. Here it is up and running.
