Some extensive googling led me to this extremely useful post on Labnol, where I read about the ImportXML function in Google Spreadsheets – and how this can be used in conjunction with Backtweets. Before too long I’d cracked my problem – I was able to generate nicely ordered spreadsheets of real-time URL search results with next to no effort. In this post I’m going to explain how you can do it too.

Basically the magnetometer in the iPhone is exactly that. It measures the magnetic field. And it is very susceptible to local changing magnetic field monitors, CPUs, TVs, anything like that will affect it quite badly. By default, what you're measuring, of course, is the ambient magnetic field of the Earth. And that's how you can use it as a digital compass because there are tables that will draw up and show you how to do deviations from magnetic north to true north, depending on your latitude and longitude.

You want to develop an iPhone app that interacts with Flickr content? This sounds pretty good. And the Flickr API provides you with an authorization workflow that is particularly adapted for this device. And Flickr members love their iPhones.

The name of the new project is Three20, after the 320-pixel-wide screen of the iPhone. The code is all hosted on github for your cloning pleasure. There is an excellent sample app called TTCatalog which lets you play with all of the various UI components. Documentation? Well… there are instructions for how to add Three20 to your project, but I am still working on comprehensive documentation for each of the classes. For now, the sample app and the code itself are your documentation.
