By Brian Leach and Nik Silver. First presented at London XPDay 2013, 25 Nov 2013. Synopsis: Travis Perkins has introduced some very modern technologies in the last few years, but half of the 120-strong software engineering team is actively developing in BASIC on its 1960s green screen technology platform. Brian and Nik show how it is possible to introduce XP practices to technology that predates the moon landings, and will discuss lessons learned. They will cover unit testing, source control, and continuous integration, and will touch briefly on future objectives.
