John Barnes was a founder member of the Ada design team and the software company Alsys UK. He gives occasional lectures on Ada and popular mathematics, and has authored 14 books, including 'Gems of Geometry' (2012) and 'Nice Numbers' (2016).

'This new revision of 'Programming In Ada' will ensure that it remains the essential companion of any Ada practitioner. It is a useful guide that brings to life the more formal language of the 'Ada Reference Manual'. As one has come to expect of John's work, it includes many practical examples which will no doubt go on to be used as templates for much real code.' Jeff Cousins, CEng FIET, Member and past Chair of the Ada Rapporteur Group
