The first major book on MDM written by Group Policy and Enterprise Mobility MVP and renowned expert, Jeremy Moskowitz! With Windows 10, organizations can create a consistent set of configurations across the modern enterprise desktop—for PCs, tablets, and phones—through the common Mobile Device Management (MDM) layer. MDM gives organizations a way to configure settings that achieve their administrative intent without exposing every possible setting. One benefit of MDM is that it enables organizations to apply broader privacy, security, and application management settings through lighter and more efficient tools. MDM also allows organizations to target Internet-connected devices to manage policies without using Group Policy (GP) that requires on-premises domain-joined devices. This makes MDM the best choice for devices that are constantly on the go. With Microsoft making this shift to using Mobile Device Management (MDM), a cloud-based policy-management system, IT professionals need to know how to do similar tasks they do with Group Policy, but now using MDM, with its differences and pitfalls. What is MDM (and how is it different than GP) Setup Azure AD and MDM Auto-Enrollment New PC Rollouts and Remote Refreshes: Autopilot and Configuration Designer Enterprise State Roaming and OneDrive Documents Roaming Renowned expert and Microsoft Group Policy and Enterprise Mobility MVP Jeremy Moskowitz teaches you MDM fundamentals, essential troubleshooting techniques, and how to manage your enterprise desktops.

Fearlessly change the design of your iOS code with solid unit tests. Use Xcode's built-in test framework XCTest and Swift to get rapid feedback on all your code - including legacy code. Learn the tricks and techniques of testing all iOS code, especially view controllers (UIViewControllers), which are critical to iOS apps. Learn to isolate and replace dependencies in legacy code written without tests. Practice safe refactoring that makes these tests possible, and watch all your changes get verified quickly and automatically. Make even the boldest code changes with complete confidence. Manual code and UI testing get slower the deeper your navigation hierarchy goes. It can take several taps just to reach a particular screen, never mind the actual workflow tests. Automatic unit testing offers such rapid feedback that it can change the rules of development. Bring testing to iOS development, even for legacy code. Use XCTest to write unit tests in Swift for all your code. iOS developers typically reserve unit tests for their model classes alone. But that approach skips most of the code common to iOS apps, especially with UIViewControllers. Learn how to unit test these view controllers to expand your unit testing possibilities. Since good unit tests form the bedrock for safe refactoring, you're empowered to make bold changes. Learn how to avoid the most common mistakes Swift programmers make with the XCTest framework. Use code coverage to find holes in your test suites. Learn how to identify hard dependencies. Reshape the design of your code quickly, with less risk and less fear.

In this radical and visionary new book, McKenzie Wark argues that the all-pervasive presence of data in our networked society has given rise to a new mode of production, one not ruled over by capitalists and their factories but by those who own and control the flow of information. Yet, if this is not capitalism anymore, could it be something worse? What if the world we're living in is more dystopian than the techno utopias of the Silicon Valley imagination? And, if this is the case, how do we find a way out? Capital Is Dead offers not only the theoretical tools to analyse this new world of information, but the ones to change it, too.Drawing on the writings of the Situationists and a range of contemporary theorists, Wark offers a vast panorama of the contemporary condition and the classes that control it.

In the nineties, neoliberalism simultaneously provided the context for the Internet’s rapid uptake in the United States and discouraged public conversations about racial politics. At the same time many scholars lauded the widespread use of text-driven interfaces as a solution to the problem of racial intolerance. Today’s online world is witnessing text-driven interfaces such as e-mail and instant messaging giving way to far more visually intensive and commercially driven media forms that not only reveal but showcase people’s racial, ethnic, and gender identity. Lisa Nakamura, a leading scholar in the examination of race in digital media, uses case studies of popular yet rarely examined uses of the Internet such as pregnancy Web sites, instant messaging, and online petitions and quizzes to look at the emergence of race-, ethnic-, and gender-identified visual cultures. While popular media such as Hollywood cinema continue to depict nonwhite nonmales as passive audiences or consumers of digital media rather than as producers, Nakamura argues the contrary—with examples ranging from Jennifer Lopez music videos; films including the Matrix trilogy, Gattaca, and Minority Report; and online joke sites—that users of color and women use the Internet to vigorously articulate their own types of virtual community, avatar bodies, and racial politics. Lisa Nakamura is associate professor of speech communication and Asian American studies at the University of Illinois, Urbana-Champaign. She is the author of Cybertypes: Race, Ethnicity, and Identity on the Internet and coeditor, with Beth Kolko and Gilbert Rodman, of Race in Cyberspace.

Why not join it? HubSpot, a Boston start-up, was flush with $100 million in venture capital. They offered Dan a pile of stock options for the nebulous role of "marketing fellow." What could possibly go wrong? What follows is a hilarious and excoriating account of Dan's time at the start-up and a revealing window onto the dysfunctional culture that prevails in a world flush with cash and devoid of experience. Filled with stories of meaningless jargon, teddy bears at meetings, push-up competitions and all-night parties, this uproarious tale is also a trenchant analysis of the dysfunctional start-up world, a de facto conspiracy between those who start companies and those who fund them. It is a world where bad ideas are rewarded with hefty investments, where companies blow money lavishing perks on their post-collegiate workforces, and where everybody is trying to hang on just long enough to cash out with a fortune.

　 DESCRIPTION Modern distributed applications must deliver near-realtime performance while simultaneously managing big data and high user loads spread across environments ranging from cloud systems to mobile devices. Unlike traditional enterprise applications which focus on decoupling their internal components by defining programming interfaces, reactive applications go one step further and decouple their components also at runtime. This makes it possible to react effectively and efficiently to failures, varying user demands, and changes in the application's execution environment. The resulting systems are highly concurrent and fault-tolerant, with minimal dependencies among individual system components. Reactive Design Patterns is a clearly-written guide for building message-driven distributed systems that are resilient, responsive, and elastic. It contains patterns for messaging, flow control, resource management, and concurrency, along with practical issues like test-friendly designs. All patterns include concrete examples using Scala and Akka—in some cases, Java, JavaScript, and Erlang. Software engineers and architects will learn patterns that address day-to-day distributed development problems in a fault-tolerant and scalable way. Project leaders and CTOs will gain a deeper understanding of the reactive design philosophy. KEY FEATURES Offers best patterns for building reactive applications All patterns include concrete examples Discover best practices Explains theory behind reactive system design principles AUDIENCE Readers should be familiar with a standard programming language like Java, C++ or C# and be comfortable with the basics of distributed systems. Although most of the book's examples use the Scala language, no prior experience with Scala or Akka is required. ABOUT THE TECHNOLOGY The design patterns in this book were collected by the consultants and engineers of Typesafe during thousands of hours spent building enterprise-quality applications using Scala and Akka. Although many reactive patterns can be implemented using standard development tools like Java, others require the capabilities offered by a functional programming language like Scala and an Actor-based concurrency system like Akka.
