Zephyr RTOS Embedded C Programming: Using Embedded RTOS POSIX API
by Andrew EliaszThese days the term Real-Time Operating System (RTOS) is used when referring to an operating system designed for use in embedded microprocessors or controllers. The “Real Time” part refers to the ability to implement applications that can rapidly responding to external events in a deterministic and predictable manner. RTOS-based applications have to meet strict deadline constraints while meeting the requirements of the application. One way of ensuring that urgent operations are handled reliably is to set task priorities on each task and to assign higher priorities to those tasks that need to respond in a more timely manner.Another feature of real-time applications is the careful design and implementation of the communication and synchronization between the various tasks. The Zephyr RTOS was developed by Wind River Systems, and subsequently open sourced. Its design and implementation are oriented towards the development of time critical IoT (Internet of Things) and IIoT (Industrial Internet of Things) applications, and, consequently it has a rich feature set for building both wireless and wired networking applications. However, with a rich feature set comes a fairly steep learning curve.This book covers the foundations of programming embedded systems applications using Zephyr's Kernel services. After introducing the Zephyr architecture as well as the Zephyr build and configuration processes, the book will focus on multi-tasking and inter-process communication using the Zephyr Kernel Services API. By analogy with embedded Linux programming books, this book will be akin a Linux course that focuses on application development using the Posix API. In this case, however, it will be the Zephyr Kernel Services API that will be the API being used as well as the Posix API features supported by Zephyr.What You’ll learnAn Overview of the Cortex-M Architecture.Advanced data structures and algorithms programming (linked lists, circular buffers and lists).How to build Zephyr Applications, including setting up a Command Line Zephyr Development Environment on Linux.Task scheduling and pre-emption patterns used in Real Time Operating Systems.Scheduling, Interrupts and Synchronization, including threads, scheduling, and system threads.Overview of Symmetric Multiprocessing (SMP) and Zephyr support for SMP. Memory management, including memory heaps, memory slabs, and memory pools.Who This Book Is ForEmbedded Systems programmers, IoT and IIoT developers, researchers, BLE application developers (Industrial Control Systems, Smart Sensors, Medical Devices, Smart Watches, Manufacturing, Robotics). Also of use to undergraduate and masters in computer science and digital electronics courses.
Zero Comments: Blogging and Critical Internet Culture (Kultur- Und Medientheorie Ser.)
by Geert LovinkIn Zero Comments, internationally renowned media theorist and 'net critic' Geert Lovink revitalizes worn out concepts about the Internet and interrogates the latest hype surrounding blogs and social network sites. In this third volume of his studies into critical Internet culture, following the influential Dark Fiber and My First Recession, Lovink develops a 'general theory of blogging.' He unpacks the ways that blogs exhibit a 'nihilist impulse' to empty out established meaning structures. Blogs, Lovink argues, are bringing about the decay of traditional broadcast media, and they are driven by an in-crowd dynamic in which social ranking is a primary concern. The lowest rung of the new Internet hierarchy are those blogs and sites that receive no user feedback or 'zero comments'. Zero Comments also explores other important changes to Internet culture, as well, including the silent globalization of the Net in which the West is no longer the main influence behind new media culture, as countries like India, China and Brazil expand their influence and looks forward to speculate on the Net impact of organized networks, free cooperation and distributed aesthetics.

The Zero Trust Framework: Threat Hunting & Quantum Mechanics
by Ravindra DasThe Cybersecurity landscape is a daunting one today. It is nothing like it was 10 years ago. Now, it has become very complex, covert, dynamic, and stealthy. It has literally become a cat and mouse game, in which the Cyberattacker is still one step ahead. This is despite all of the technology that is available to us a society, which includes Artificial Intelligence (AI) and Machine Learning. Part of the other problem is that human beings are resistant to change. For example, the password is still the favored way of authenticating and authorizing an individual, but it too has shown its grave limitations. Despite the use of Password Managers, which can create long and complex passwords, people still resort to their old fashioned ways of doing things. So what is needed now is an extreme change, in which, unfortunately, people have no choice in whether or not they will participate. It is called the Zero Trust Framework, and in this methodology, absolutely nobody can be trusted in either the internal or the external environments. The mantra here is to keep verifying everybody, all the time. The Zero Trust Framework also involves the concept of segmentation, in which the IT and Network Infrastructure of a business is broken down into smaller components, much like a Subnet. Each component will have its own layer of security, and every individual must be authenticated via the use of Multifactor Authentication (MFA). In this book, we review both the concepts and mechanics behind the Zero Trust Framework. We also introduce advanced technologies into it, including the use of Biometrics, the Public Key Infrastructure, and Quantum Mechanics/Quantum Cryptography.

The Zero Trust Framework and Privileged Access Management (PAM)
by Ravindra DasThis book is about the Zero Trust Framework. Essentially, this is a methodology where the IT/Network Infrastructure of a business is segmented into smaller islands, each having its own lines of defense. This is primarily achieved through the use of Multifactor Authentication (MFA), where at least three more authentication layers are used, preferably being different from one another.Another key aspect of the Zero Trust Framework is known as Privileged Access Management (PAM). This is an area of Cybersecurity where the protection of superuser accounts, rights, and privileges must be protected at all costs from Cyberattackers. In this regard, this is where the Zero Trust Framework and PAM intertwine, especially in a Cloud-based platform, such as Microsoft Azure.However, as it has been reviewed in one of our previous books, the use of passwords is now becoming a nemesis, not only for individuals but for businesses as well. It is hoped that by combining the Zero Trust Framework with PAM, password use can be eradicated altogether, thus giving rise to a passwordless society.

Zeroing Dynamics, Gradient Dynamics, and Newton Iterations
by Yunong Zhang Lin Xiao Zhengli Xiao Mingzhi MaoNeural networks and neural dynamics are powerful approaches for the online solution of mathematical problems arising in many areas of science, engineering, and business. Compared with conventional gradient neural networks that only deal with static problems of constant coefficient matrices and vectors, the authors’ new method called zeroing dynamics solves time-varying problems. Zeroing Dynamics, Gradient Dynamics, and Newton Iterations is the first book that shows how to accurately and efficiently solve time-varying problems in real-time or online using continuous- or discrete-time zeroing dynamics. The book brings together research in the developing fields of neural networks, neural dynamics, computer mathematics, numerical algorithms, time-varying computation and optimization, simulation and modeling, analog and digital hardware, and fractals. The authors provide a comprehensive treatment of the theory of both static and dynamic neural networks. Readers will discover how novel theoretical results have been successfully applied to many practical problems. The authors develop, analyze, model, simulate, and compare zeroing dynamics models for the online solution of numerous time-varying problems, such as root finding, nonlinear equation solving, matrix inversion, matrix square root finding, quadratic optimization, and inequality solving.
