Computer Says Oh No!

About the event

Software is running the world but why is it still crashing? 

A spreadsheet bug gave us austerity economics. An overlooked software detail knocked out O2's 4G network. The WannaCry ransomware attack exploited a bug in Windows, infecting computers in over 150 countries and bringing the NHS to its knees. In October 2020 an overlooked limitation in Excel led to COVID-19 cases being underreported. 

Software reliability is not simply a question of consumer inconvenience and business priorities; it has economic, social and cultural consequences. So what is it about software systems that led to these failures? What are the moral and practical implications for those involved in software development?

In this Sidney Michaelson Memorial Lecture, author and software consultant Kevlin Henney explores mistakes in software, its application and how they affect the different levels of our society.
