Audrey Tam is an author of this book. As a retired computer science academic, she’s a technology generalist with expertise in translating new knowledge into learning materials. Audrey attends nearly all Melbourne Cocoaheads monthly meetings, attends many concerts at Tempo Rubato and does most of her writing and zooming at Rubato Upstairs. She also enjoys long train journeys, knitting, and trekking in the Aussie wilderness.

Caroline Begbie is another author of this book. Caroline ventured out into the world as an unemployed classicist. She then taught herself to code and started up a software company in the UK and later in the US. Retiring to Australia prematurely, she performed marionette shows for pre-schools until she purchased the original iPad. She recognized the creative possibilities and became an indie iOS developer. Now she loves tinkering with vertices and watching Disney movies.
