Devices of the Soul: Battling for Our Selves in an Age of Machines
by Steve Talbott"Self-forgetfulness is the reigning temptation of the technological era. This is why we so readily give our assent to the absurd proposition that a computer can add two plus two, despite the obvious fact that it can do nothing of the sort--not if we have in mind anything remotely resembling what we do when we add numbers. In the computer's case, the mechanics of addition involve no motivation, no consciousness of the task, no mobilization of the will, no metabolic activity, no imagination. And its performance brings neither the satisfaction of accomplishment nor the strengthening of practical skills and cognitive capacities." In this insightful book, author Steve Talbott, software programmer and technical writer turned researcher and editor for The Nature Institute, challenges us to step back and take an objective look at the technology driving our lives. At a time when 65 percent of American consumers spend more time with their PCs than they do with their significant others, according to a recent study, Talbott illustrates that we're forgetting one important thing--our Selves, the human spirit from which technology stems. Whether we're surrendering intimate details to yet another database, eschewing our physical communities for online social networks, or calculating our net worth, we freely give our power over to technology until, he says, "we arrive at a computer's-eye view of the entire world of industry, commerce, and society at large...an ever more closely woven web of programmed logic." Digital technology certainly makes us more efficient. But when efficiency is the only goal, we have no way to know whether we're going in the right or wrong direction. Businesses replace guiding vision with a spreadsheet's bottom line. Schoolteachers are replaced by the computer's dataflow. Indigenous peoples give up traditional skills for the dazzle and ease of new gadgets. Even the Pentagon's zeal to replace "boots on the ground" with technology has led to the mess in Iraq. And on it goes. The ultimate danger is that, in our willingness to adapt ourselves to technology, "we will descend to the level of the computational devices we have engineered--not merely imagining ever new and more sophisticated automatons, but reducing ourselves to automatons." To transform our situation, we need to see it in a new and unaccustomed light, and that's what Talbott provides by examining the deceiving virtues of technology--how we're killing education, socializing our machines, and mechanizing our society. Once you take this eye-opening journey, you will think more clearly about how you consume technology and how you allow it to consume you. "Nothing is as rare or sorely needed in our tech-enchanted culture right now as intelligent criticism of technology, and Steve Talbott is exactly the critic we've been waiting for: trenchant, sophisticated, and completely original. Devices of the Soul is an urgent and important book." --Michael Pollan, author of The Omnivore's Dilemma: A Natural History of Four Meals and The Botany of Desire: A Plant's Eye View of the World "Steve Talbott is a rare voice of clarity, humanity, and passion in a world enthralled by machines and calculation. His new book, Devices of the Soul, lays out a frightening and at the same time inspiring analysis of what computers and computer-like thinking are doing to us, our children, and the future of our planet. Talbott is no Luddite. He fully understands and appreciates the stunning power of technology for both good and evil. His cool and precise skewering of the fuzzy thinking and mindless enthusiasm of the technology true believers is tempered by his modesty, the elegance of his writing, and his abiding love for the world of nature and our capacity for communion with it. " --Edward Miller, Former editor, Harvard Education Letter "Those who care about the healthy and wholesome lives of children can gain much from Steve Talbott's wisdom. He examines the need to help children spend more time touching nature and real life and less touching keyboards. He eloquently questions th...

DevOps, DBAs, and DBaaS
by Michael S. CuppettLearn how DBAs in a DevOps environment manage data platforms and change requests to support and optimize continuous integration, delivery, testing, and deployment in the application development life cycle. On the Dev side, DBAs evaluate change requests to ensure compliance with organizational best practices and guard against degradation of database performance and the validity of dependent objects. On the Ops side, DBAs perform release and troubleshooting activities in support of the application, manage the data platform's access and security, and monitor and maintain performance of the databases that they have designed and provisioned. DevOps, DBAs, and DBaaS investigates the complex intersection between DBA functions and DevOps processes. DevOps teams traditionally viewed DBAs as process outliers who disrupt and retard SDLC timelines. At each touch point, veteran DBA Mike Cuppett shows how DBAs can most effectively contribute to decreasing release cycle times and improving product resiliency by applying automation, orchestration, and DBaaS solutions to database administration in ways that dovetail with DevOps requirements and metrics. At a high level, Cuppett demonstrates the importance of leveling silo walls in the IT supply chain and of measuring application performance holistically by reference to satisfaction of customer requirements and end-user experience. At a technical level, he drills into topics and case studies on diagnosing and resolving problems commonly encountered by DBAs and DevOps teams when meshing database management with application delivery. What You Will Learn: Understand techniques and best practices at all points of collaboration between DBAs and DevOps teams in product development Use tools for measuring DBA inputs to DevOps processes by using the holistic criteria of end-user experience and business requirement Integrate open source database technologies with DevOps Know when to decouple application and database layers and move to DBaaS models Overcome language and mindset barriers between DBAs and DevOps teams Who This Book Is For: DBAs who are leaning toward or already involved with DevOps and DevOps engineers, team leaders, developers and product managers who are already working with DBAs or planning to integrate DBAs in DevOps teams. The secondary readership is executives and managers in companies that practice DevOps.
DevOps for Airborne Software: Exploring Modern Approaches (SpringerBriefs in Computer Science)
by Wanja Zaeske Umut DurakThis Springer Brief presents a selection of tools and techniques which either enable or improve the use of DevOps for airborne software engineering. They are evaluated against the unique challenges of the aviation industry such as safety and airworthiness, and exercised using a demonstrator in order to gather first experience. The book is structured as follows: after a short introduction to the main topics of the work in chapter 1, chapter 2 provides more information on the tools, techniques, software and standards required to implement the subsequently presented ideas. In particular, the development practice BDD, the relation between DevOps, CI & CD and both the Rust & the Nix programming language are introduced. In chapter 3 the authors explain and justify their ideas towards advancing the state of the art, mapping the aforementioned tools and techniques to the DevOps Cycle while considering aspects of Do-178C. Next, in chapter 4 the experiences gathered while implementing a demonstrator using the tools and techniques are described. Eventually, chapter 5 briefly summarizes the findings and presents a compilation of open points and missing pieces which are yet to be resolved. The book targets three different reader groups. The first one are development managers from the aerospace industry who need to see examples and experience reports for the application of DevOps for airborne software. The second group are investigators in the safety-critical embedded systems domain who look for benchmarks at various application domains. And the third group are lecturers who offer graduate level software engineering courses for safety-critical software engineering.
