Over the last couple of days I have been investigating the pull to refresh paradigm, and its possible implementation in an Android app. A quick Google search produces this library from Chris Banes, and this fork from Naver Communications. They are however for my use cases too complex and not

For one of my web based projects I needed to acquire some data. Data in the modern day and age is often the most valuable asset of a company... it got me thinking. The Royal Mail here in the UK offer a Postcode Address File (PAF) to any entity who
