In this episode of Rule-breakers, Sean talks to Peter Flynn, an expert in markup languages and typesetting. With a background in traditional printing and computer typesetting, Peter transitioned into academia at UCC, where he became involved in early web development. He met Tim Berners-Lee while serving on a European Community committee, witnessing the demonstration of the nascent World Wide Web. Inspired, Peter downloaded the source code and launched Ireland's first website, subsequently contributing to discussions on HTML standardization.
