This book offers a comprehensive scholarly overview of Reddit, one of the most popular and least studied social platforms of the early 21st century. The book inspires new ways of thinking about Reddit, considering it from multiple perspectives: through a historical lens, as a site where identity is forged, as a democracy, as a community, and as a news aggregator and distributor. By bringing theories from computer-mediated communication, communication studies, and sociology to bear on original, large-scale observational analyses of Reddit’s communities, this book provides a uniquely comprehensive overview of the platform’s first 15 years. Understanding Reddit will help us make sense of how rapidly growing communities function in an era of mass online anonymity. Serving both as a primer on how social behavior on Reddit plays out, and as a way of locating it within multiple theoretical traditions, the book will offer important insights to scholars and students in the disciplines of communication, media studies, information science, internet and emerging media studies, and sociology.
From a master of professional photography, a book that explores the exciting possibilities of artificial light. This guide to on- and off-camera flash picks up where Peterson's previous title, Understanding Exposure, left off--helping free photographers from the limitations of auto to get the images they want when natural light isn't enough. For the many amateur photographers afraid to venture past natural lighting, here is the book that will finally help them master artificial light. In his trademark easy-to-understand style, Bryan Peterson explains not only how flash works, but how to go beyond TTL automatic flash exposure to master manual flash, allowing readers to control the quality, shape and direction of light for a perfect exposure, every time.
*Now a major motion picture starring Saoirse Ronan and Paul Mescal* A taut, psychological thriller from Iain Reid, “one of the most talented purveyors of weird, dark narratives in contemporary fiction” (Los Angeles Review of Books). Severe climate change has ravaged the country, leaving behind a charred wasteland. Junior and Henrietta live a comfortable if solitary life on one of the last remaining farms. Their private existence is disturbed the day a stranger comes to the door with alarming news. Junior has been randomly selected to travel far away from the farm, but the most unusual part is that arrangements have already been made so that when he leaves, Henrietta won’t have a chance to miss him. She won’t be left alone—not even for a moment. Henrietta will have company. Familiar company. Told in Iain Reid’s sparse, biting style, Foe is a “mind-bending and genre-defying work of genius” (Liz Nugent, author of Unraveling Oliver) that will stay with you long after you turn the final page.
Freedom Libraries: The Untold Story of Libraries for African-Americans in the South. As the Civil Rights Movement exploded across the United States, the media of the time was able to show the rest of the world images of horrific racial violence. And while some of the bravest people of the 20th century risked their lives for the right to simply order a cheeseburger, ride a bus, or use a clean water fountain, there was another virtually unheard of struggle—this one for the right to read. Although illegal, racial segregation was strictly enforced in a number of American states, and public libraries were not immune. Numerous libraries were desegregated on paper only: there would be no cards given to African-Americans, no books for them read, and no furniture for them to use. It was these exact conditions that helped create Freedom Libraries. Over eighty of these parallel libraries appeared in the Deep South, staffed by civil rights voter registration workers. While the grassroots nature of the libraries meant they varied in size and quality, all of them created the first encounter many African-Americans had with a library. Terror, bombings, and eventually murder would be visited on the Freedom Libraries—with people giving up their lives so others could read a library book. This book delves into how these libraries were the heart of the Civil Rights Movement, and the remarkable courage of the people who used them. They would forever change libraries and librarianship, even as they helped the greater movement change the society these libraries belonged to. Photographs of the libraries bring this little-known part of American history to life.
"Mathematical thinking is not the same as 'doing math'--unless you are a professional mathematician. For most people, 'doing math' means the application of procedures and symbolic manipulations. Mathematical thinking, in contrast, is what the name reflects, a way of thinking about things in the world that humans have developed over three thousand years. It does not have to be about mathematics at all, which means that many people can benefit from learning this powerful way of thinking, not just mathematicians and scientists."--Back cover.
Despite the proliferation of video games in the twenty-first century, the theory of game design is largely underdeveloped, leaving designers on their own to understand what games really are. Helping you produce better games, Game Design Theory: A New Philosophy for Understanding Games presents a bold new path for analyzing and designing games.

This easy-to-follow guide will have you up and running with writing kernel code in next-to-no time. This book uses the latest 5.4 Long-Term Support (LTS) Linux kernel, which will be maintained from November 2019 through to December 2025. By working with the 5.4 LTS kernel throughout the book, you can be confident that your knowledge will continue to be valid for years to come. You’ll start the journey by learning how to build the kernel from the source. Next, you’ll write your first kernel module using the powerful Loadable Kernel Module (LKM) framework. The following chapters will cover key kernel internals topics including Linux kernel architecture, memory management, and CPU scheduling. During the course of this book, you’ll delve into the fairly complex topic of concurrency within the kernel, understand the issues it can cause, and learn how they can be addressed with various locking technologies (mutexes, spinlocks, atomic, and refcount operators). You’ll also benefit from more advanced material on cache effects, a primer on lock-free techniques within the kernel, deadlock avoidance (with lockdep), and kernel lock debugging techniques. By the end of this kernel book, you’ll have a detailed understanding of the fundamentals of writing Linux kernel module code for real-world projects and products.What you will learn Write high-quality modular kernel code (LKM framework) for 5.x kernels Configure and build a kernel from source Explore the Linux kernel architecture Get to grips with key internals regarding memory management within the kernel Understand and work with various dynamic kernel memory alloc/dealloc APIs Discover key internals aspects regarding CPU scheduling within the kernel Gain an understanding of kernel concurrency issues Find out how to work with key kernel synchronization primitives Who this book is for This book is for Linux programmers beginning to find their way with Linux kernel development.

What is the relation between time and change? Does time depend on the mind? Is the present always the same or is it always different? Aristotle tackles these questions in the Physics, and Time for Aristotle is the first book in English devoted to this discussion. Aristotle claims that time is not a kind of change, but that it is something dependent on change; he defines it as a kind of 'number of change'. Ursula Coope argues that what this means is that time is a kind of order (not, as is commonly supposed, a kind of measure). It is universal order within which all changes are related to each other. This interpretation enables Coope to explain two puzzling claims that Aristotle makes: that the now is like a moving thing, and that time depends for its existence on the mind. Brilliantly lucid in its explanation of this challenging section of the Physics, Time for Aristotle shows his discussion to be of enduring philosophical interest.
There are many reasons why neural networks fascinate us and have captivated headlines in recent years. They make web searches better, organize photos, and are even used in speech translation. Heck, they can even generate encryption. At the same time, they are also mysterious and mind-bending: how exactly do they accomplish these things ? What goes on inside a neural network?On a high level, a network learns just like we do, through trial and error. This is true regardless if the network is supervised, unsupervised, or semi-supervised. Once we dig a bit deeper though, we discover that a handful of mathematical functions play a major role in the trial and error process. It also becomes clear that a grasp of the underlying mathematics helps clarify how a network learns. In the following chapters we will unpack the mathematics that drive a neural network. To do this, we will use a feedforward network as our model and follow input as it moves through the network.
