Understanding distributed computing is not an easy task. This is due to the many facets of uncertainty one has to cope with and master in order to produce correct distributed software. Considering the uncertainty created by asynchrony and process crash failures in the context of message-passing systems, the book focuses on the main abstractions that one has to understand and master in order to be able to produce software with guaranteed properties. These fundamental abstractions are communication abstractions that allow the processes to communicate consistently (namely the register abstraction and the reliable broadcast abstraction), and the consensus agreement abstractions that allows them to cooperate despite failures. As they give a precise meaning to the words "communicate" and "agree" despite asynchrony and failures, these abstractions allow distributed programs to be designed with properties that can be stated and proved. Impossibility results are associated with these abstractions. Hence, in order to circumvent these impossibilities, the book relies on the failure detector approach, and, consequently, that approach to fault-tolerance is central to the book. Table of Contents: List of Figures / The Atomic Register Abstraction / Implementing an Atomic Register in a Crash-Prone Asynchronous System / The Uniform Reliable Broadcast Abstraction / Uniform Reliable Broadcast Abstraction Despite Unreliable Channels / The Consensus Abstraction / Consensus Algorithms for Asynchronous Systems Enriched with Various Failure Detectors / Constructing Failure Detectors

Pro Asynchronous Programming with .NET teaches the essential skill of asynchronous programming in .NET. It answers critical questions in .NET application development, such as: how do I keep my program responding at all times to keep my users happy? how do I make the most of the available hardware? how can I improve performance? In the modern world, users expect more and more from their applications and devices, and multi-core hardware has the potential to provide it. But it takes carefully crafted code to turn that potential into responsive, scalable applications. With Pro Asynchronous Programming with .NET you will: Meet the underlying model for asynchrony on Windows—threads. Learn how to perform long blocking operations away from your UI thread to keep your UI responsive, then weave the results back in as seamlessly as possible. Master the async/await model of asynchrony in .NET, which makes asynchronous programming simpler and more achievable than ever before. Solve common problems in parallel programming with modern async techniques. Get under the hood of your asynchronous code with debugging techniques and insights from Visual Studio and beyond. In the past asynchronous programming was seen as an advanced skill. It’s now a must for all modern developers. Pro Asynchronous Programming with .NET is your practical guide to using this important programming skill anywhere on the .NET platform.

Children are growing up in a world of screens. They move seamlessly back and forth in a physical-digital environment. But parents are both worried and confused about when and how to introduce tablets, smartphones, even television. When it comes to navigating kids' use of media, all-or-nothing approaches are doomed to fail. Giving children free reign over their screen use carries potential risks to their physical and mental health and their emotional and social development. Yet rejecting digital media is undesirable (and probably impossible), since today's kids must navigate that realm to succeed in school and the world in which, as adults, they'll be expected to function well in a technology-rich environment. So how do we help young people establish mastery of screens and harness them for healthy development and social engagement? Features include: Ask the Mediatrician: questions and answers based on Dr. Rich’s long-running advice column and podcast Media Rx: prescriptive content based on insights from the Digital Wellness Lab and CIMAID Let’s Chat: detailed discussions of special topics in media use and how to talk with your child about them Digital Wellness Toolkit: a one-stop guide for actionable advice that you can customize for your family's specific needs Backed by evidence as well as decades of professional and personal practice, The Mediatrican's Guide will give parents peace of mind and kids much-needed tools to navigate digital media for the rest of their lives.
