Information security is broken. Year after year, attackers remain unchallenged and undeterred, while engineering teams feel mounting pressure to design, build, and operate "secure" systems. Attacks can't be prevented, mental models of systems are incomplete, and our digital world constantly evolves. How can we verify that our systems behave the way we expect? What can we do to improve our systems' resilience? In this pragmatic and comprehensive guide, authors Kelly Shortridge and Aaron Rinehart help you navigate the challenges of securing complex software systems. Using the principles and practices of security chaos engineering, they explore how you can cultivate resilience across the software delivery lifecycle. Attackers and systems will change, but by preparing for adverse events you can ensure it does not disrupt your ability to innovate, move quickly, and achieve your engineering and business goals. You will: Learn how to design a modern security program aligned to business and engineering goals Make informed decisions at each phase of software delivery to nurture resilience to attack Understand the complex systems dynamics upon which security outcomes depend Navigate technical and organizational trade-offs that distort defensive decision making Explore chaos experimentation as a tool for verifying critical assumptions about systems security and the ROI of security investments Peek behind the scenes of major enterprises that leverage security chaos engineering and learn from their practices

We live in a moment of high anxiety around digital transformation. Computers are blamed for generating toxic forms of culture and ways of life. Once part of future imaginaries that were optimistic or even utopian, today there is a sense that things have turned out very differently. Anti-computing is widespread. This book seeks to understand its cultural and material logics, its forms, and its operations. Anti-Computing critically investigates forgotten histories of dissent - moments when the imposition of computational technologies, logics, techniques, imaginaries, utopias have been questioned, disputed, or refused. It asks why dissent is forgotten and how - under what circumstances - it revives. Constituting an engagement with media archaeology/medium theory and working through a series of case studies, this book is compelling reading for scholars in digital media, literary, cultural history, digital humanities and associated fields at all levels. -- .

Steps forward in mathematics often reverberate in other scientific disciplines, and give rise to innovative conceptual developments or find surprising technological applications. This volume brings to the forefront some of the proponents of the mathematics of the twentieth century, who have put at our disposal new and powerful instruments for investigating the reality around us. The portraits present people who have impressive charisma and wide-ranging cultural interests, who are passionate about defending the importance of their own research, are sensitive to beauty, and attentive to the social and political problems of their times. What we have sought to document is mathematics' central position in the culture of our day. Space has been made not only for the great mathematicians but also for literary texts, including contributions by two apparent interlopers, Robert Musil and Raymond Queneau, for whom mathematical concepts represented a valuable tool for resolving the struggle between 'soul and precision.'

The Chaos Machine is an essential book for our times - Ezra Klein The Chaos Machine is the story of how the world was driven mad by social media. The election of populists like Trump and Bolsonaro; strife and genocide in countries like Myanmar; the rampant spread of COVID-19 conspiracy theories as deadly as the pandemic itself; all of these are products of a breakdown in our social and political lives, a breakdown driven by the apps, companies and algorithms that compete constantly for our attention. Max Fisher is a leading New York Times technology reporter whose work has covered the way that social media sites - driven increasingly by artificial intelligence rather than human ingenuity - push users towards more and more extreme positions, deepening the divisions in society in pursuit of greater engagement and profit. With extraordinary access to the most powerful players in Silicon Valley, and with testimonies from around the world of the havoc being wreaked by our online selves, The Chaos Machine shows us how we got to this uniquely perilous moment - and how we might get out of it.

Sketching is a natural and intuitive communication tool used for expressing concepts and ideas that are difficult to communicate through text or speech alone. In design applications, drawings are used at various stages of the design process: from the early concept drawings scribbled on a piece of paper to immersive interactions in which users manipulate and adjust the 3D form of an object in virtual or augmented reality environments. This variety in drawing activities brings about the need for different interpretation strategies that support not only the sketching activity itself, but also allow sketch-based interactions, such as sketch-based queries, to take place. In this book, we explore the different drawing approaches used in design and the algorithms required for processing and interpreting the different sketches and drawings in design. The book is divided into two parts. The first part focuses on sketching in the 2D domain. This includes the digitization of offline and paper-based sketches, techniques for online sketch recognition, observations of user drawing habits, algorithms for inferring depth from 2D drawings, as well as non-photorealistic rendering techniques that are then applied to sketch-based queries. The second part of the book focuses on 3D sketching in virtual or augmented reality spaces. Here, we present the processing and rendering of the 3D strokes, the different interaction devices available for 3D sketching, and look at different applications where immersive 3D sketching has been applied with success.
