David spent his formative years as a Subaltern on the Hohne Artillery ranges in Germany and the back streets of the Bogside. He had his first brush with computers on FACE in the back of a Land Rover, entering the profession on leaving the army, and skilfully avoiding stepping on any passing bandwagon. At the end of the millennium, he was diagnosed with cancer and bought a derelict barn, simultaneously. His remission period was spent labouring whilst his wife, Jan, adeptly managed the rebuild, subsequently running it for 20 years as a B&B. As a freelancer he now writes and edits a computer magazine for the construction industry, covering subjects like AI, augmented reality in the industrial Metaverse, drone technology, and the industry's challenges with climate change, sustainability and Net Zero carbon processes.
