Near Field Communication (NFC) is an emerging short-range radio technology that is poised to revolutionise how we use mobile phones in everyday interactions. In this webinar, Andreas Jakl of Mopius introduces the basics of NFC and how the technology is implemented in Nokia Lumia phones. He also demonstrates how you can use NFC from the Microsoft Windows Phone 8 Proximity API in your applications to share content, read data from and write data to NFC tags, and create your own application-launch tags.

It is recommended that you install the Microsoft Windows Phone SDK 8.0 to get the most out of this training lab. Also, it will be helpful to have a Nokia Lumia phone built on Windows Phone 8 available for testing.

Stegafoto: a lens which embeds audio and text inside images by vnuckcha

Embedding text or audio within an image can make it easier for the photographer to vividly re-live the experience when browsing an image months after it has been taken. The technique used here is “fat-free” (does not increase the size of the image) and does not visibly distort or affect the quality of the image. Briefly put, the technique uses the principle of Steganography with a simple “even-odd” encoding scheme in the least significant bits of the pixels in the image.

The article explains how this result has been achieved at two levels. The first part is structured so that even someone with no programming experience should be able to get a feel for how it works – all you need is an open mind. The “Technical Details” parts that follow assume that the reader is familiar with C# and Javascript programming.
