Mark Goody has been writing software on various platforms since he was but a child. These days he concentrates on Apple platforms, although he can be tempted to experiment with most things. He lives just outside Belfast, Northern Ireland, with his wife and two sons. They look after him by making sure he remembers to step away from his computer from time to time. Mark blogs sporadically at marramgrass.org.uk and more reliably tweets as @marramgrass.
Maurice Kelly has been engineering software since leaving university in 2001. After spending many years working on server software for mobile telecoms, he took a change of direction to work at the user-facing end by becoming an iOS developer. He has a love for synthesizers and music, and dreams of owning a Land Rover Defender someday. He lives with his wife and children just outside Dromara, a small village in Northern Ireland.
