Being a developer type I couldn't wait to start experimenting with coding on my new HTC Desire. Being Android powered it is very friendly and coding mainly takes place in Java, which I'm familiar with. This class of mobile device is incredibly powerful of course, armed not just with portability and web access but also decent processing power and a variety of sensors. We're still learning about what exactly this means and what opportunities it can bring and so it is very important to be able to experiment, try out ideas and build rough prototypes. This is where the Android Scripting Environment (ASE) comes in, and I used it to build a prototype application to scan a barcode on a book and use that code to see if it is in a library. Handy when deciding whether to buy a book!
Breaking news! Facebook could be introducing QR codes to profile pages soon. These codes, for those of you who don't know, are a bit like the barcodes you find on products you might buy in your local shop, but are capable of holding more complex information such as a website address or a short message. Interestingly the functionality seems to have disappeared now, but after seeing this tweet (which pointed to some more information available at: http://www.technicavita.org/social-tech/mobile-sites/introduction-to-mobile-barcode-qr-technology.html):
