Mainstreaming and Game Journalism (Playful Thinking)
by David B. Nieborg Maxwell FoxmanWhy games are still niche and not mainstream, and how journalism can help them gain cultural credibility.Mainstreaming and Game Journalism addresses both the history and current practice of game journalism, along with the roles writers and industry play in conveying that the medium is a &“mainstream&” form of entertainment. Through interviews with reporters, David B. Nieborg and Maxwell Foxman retrace how the game industry and journalists started a subcultural spiral in the 1980s that continues to this day. Digital play became increasingly exclusionary by appealing to niche audiences, relying on hardcore fans and favoring the male gamer stereotype. At the same time, this culture pushed journalists to the margins, leaving them toiling to find freelance gigs and deeply ambivalent about their profession.Mainstreaming and Game Journalism also examines the bumpy process of what we think of as &“mainstreaming.&” The authors argue that it encompasses three overlapping factors. First, for games to become mainstream, they need to become more ubiquitous through broader media coverage. Second, an increase in ludic literacy, or how-to play games, determines whether that greater visibility translates into accessibility. Third, the mainstreaming of games must gain cultural legitimacy. The fact that games are more visible does little if only a few people take them seriously or deem them worthy of attention. Ultimately, Mainstreaming and Game Journalism provocatively questions whether games ever will—or even should—gain widespread cultural acceptance.

The Peep Diaries
by Hal Niedzviecki"Take a peek at The Peep Diaries, an erudite (but not too erudite) look at the culture that Facebook, Twitter, et al. have spawned."--Real Simple "It's a great read; it mixes frank interviews with people pushing the boundaries of voyeurism and exhibitionism, alongside a bracing critique of the social context that got us into peep culture and the forces that now exploit our participation in it."--The Globe and Mail We have entered the age of "peep culture": a tell-all, show-all, know-all digital phenomenon that is dramatically altering notions of privacy, individuality, security, and even humanity. Peep culture is reality TV, YouTube, MySpace, Facebook, Twitter, over-the-counter spy gear, blogs, chat rooms, amateur porn, surveillance technology, Dr. Phil, Borat, cell phone photos of your drunk friend making out with her ex-boyfriend, and more. In the age of peep, core values and rights we once took for granted are rapidly being renegotiated, often without our even noticing. With hilarious, exasperated acuity, social critic Hal Niedzviecki dives into peep, starting his own video blog, joining every social network that will have him, monitoring the movements of his toddler, selling his secrets on Craigslist, hiring a private detective to investigate him, spying on his neighbors, trying out for reality TV shows, and stripping for the pleasure of a web audience he isn't even sure exists. Part travelogue, part diary, part meditation and social history, The Peep Diaries explores a rapidly emerging digital phenomenon that is radically changing not just the entertainment landscape, but also the firmaments of our culture and society. The Peep Diaries introduces the arrival of the age of peep culture and explores its implications for entertainment, society, sex, politics, and everyday life. Mixing first-rate reporting with sociological observations culled from the latest research, this book captures the shift from pop to peep and the way technology is turning gossip into documentary and Peeping Toms into entertainment journalists. Packed with stranger-than-fiction true-life characters and scenarios, The Peep Diaries reflects the aspirations and confusions of the growing number of people willing to trade the details of their private lives for catharsis, attention, and notoriety. Hal Niedzviecki is the editor of Broken Pencil magazine and has published numerous works of social commentary and fiction, including Hello I'm Special: How Individuality Became the New Conformity.

Lighting & Design for Portrait Photography
by Neil Van NiekerkSome photographers make portraits that we can’t take our eyes off of. These images create mood, evoke emotion, and pique our curiosity. They have that certain something that other portraits seem to lack. These rare images are memorable-the kind of shots that clients want and photographers strive to emulate. These portraits are technically precise and have style. Neil van Niekerk is a big name in the portrait and wedding photography industry. His masterful photographs get a reaction, and he’s devoted to helping others create compelling portraits for their clients. In this book, van Niekerk shows readers strategies for creating a wide range of portrait looks (romantic, fun, sweet, dramatic, glamorous, or moody) in lackluster, middle-of-nowhere locales, small home studios, big expanses, and even on rooftops. Starting with traditional lighting and posing strategies and moving through "spicier” varieties, he shows readers how integrating specialized lighting (rim lighting, backlighting, flare, and low-key lighting-using natural light and artificial sources) and compositional approaches (shallow depth of field, lens compression, and unorthodox perspectives) into their creative approach can allow them to take full creative control over their portrait-taking process so that they’re able to deliver incredible shots of their clients in any photographic conditions.

On-camera Flash: Techniques For Digital Wedding And Portrait Photography
by Neil Van NiekerkPhotographers are always looking for perfect light. Unfortunately, the quality of available light, and the situations in which photos are created, are rarely perfect. This is especially true when photographing weddings or portraits on location. So while finding beautiful existing light is every photographer’s ideal, it isn’t always possible. This is the point at which photographers tend to reach for a portable, on-camera flash. Indeed, these intense light sources can prove invaluable, but only if you know how to use them effectively. In the hands of an inexperienced photographer, on-camera flash will produce images that look flat and lifeless--images with harsh shadows, washed-out skin tones, cavernous black backgrounds, and other unappealing visual characteristics. In this book, acclaimed wedding and portrait photographer Neil van Niekerk shows you how to avoid the pitfalls photographers new to speedlights often encounter so that you can produce professional images using on-camera flash. You’l learn to use simple accessories to manipulate the quality of light from your flash and how to improve a lighting scenario by enhancing rather than overwhelming the existing light. When the available light is too low and too uneven to be combined with flash, he shows you how to override it completely with flash and, with some thought and careful application of specialized techniques, still get results that look great. On-camera flash is one of the most challenging light sources to master, but with the techniques in this book you’ll learn to use it with confidence. For wedding and environmental portrait photographers who must work in ever-changing lighting scenarios, this can mean better images and better sales.

Internet Histories
by Niels Brügger, Gerard Goggin, Ian Milligan and Valérie SchaferIn 2017, the new journal Internet Histories was founded. As part of the process of defining a new field, the journal editors approached leading scholars in this dynamic, interdisciplinary area. This book is thus a collection of eighteen short thought-provoking pieces, inviting discussion about Internet histories. They raise and suggest current and future issues in the scholarship, as well as exploring the challenges, opportunities, and tensions that underpin the research terrain. The book explores cultural, political, social, economic, and industrial dynamics, all part of a distinctive historiographical and theoretical approach which underpins this emerging field.The international specialists reflect upon the scholarly scene, laying out the field’s research successes to date, as well as suggest the future possibilities that lie ahead in the field of Internet histories. While the emphasis is on researcher perspectives, interviews with leading luminaries of the Internet’s development are also provided. As histories of the Internet become increasingly important, Internet Histories is a useful roadmap for those contemplating how we can write such works. One cannot write many histories of the 1990s or later without thinking of digital media – and we hope that Internet Histories will be an invaluable resource for such studies. This book was originally published as the first issue of the Internet Histories journal.
Practical Fairness: Achieving Fair And Secure Data Models
by Aileen NielsenFairness is an increasingly important topic as machine learning and AI more generally take over the world. While this is an active area of research, many realistic best practices are emerging at all steps along the data pipeline, from data selection and preprocessing to blackbox model audits. This book will guide you through the technical, legal, and ethical aspects of making your code fair and secure while highlighting cutting edge academic research and ongoing legal developments related to fairness and algorithms.There is mounting evidence that the widespread deployment of machine learning and artificial intelligence in business and government is reproducing the same biases we are trying to fight in the real world. For this reason, fairness is an increasingly important consideration for the data scientist. Yet discussions of what fairness means in terms of actual code are few and far between. This code will show you how to code fairly as well as cover basic concerns related to data security and privacy from a fairness perspective.

Introduction to HPC with MPI for Data Science
by Frank NielsenThis gentle introduction to High Performance Computing (HPC) for Data Science using the Message Passing Interface (MPI) standard has been designed as a first course for undergraduates on parallel programming on distributed memory models, and requires only basic programming notions. Divided into two parts the first part covers high performance computing using C++ with the Message Passing Interface (MPI) standard followed by a second part providing high-performance data analytics on computer clusters. In the first part, the fundamental notions of blocking versus non-blocking point-to-point communications, global communications (like broadcast or scatter) and collaborative computations (reduce), with Amdalh and Gustafson speed-up laws are described before addressing parallel sorting and parallel linear algebra on computer clusters. The common ring, torus and hypercube topologies of clusters are then explained and global communication procedures on these topologies are studied. This first part closes with the MapReduce (MR) model of computation well-suited to processing big data using the MPI framework. In the second part, the book focuses on high-performance data analytics. Flat and hierarchical clustering algorithms are introduced for data exploration along with how to program these algorithms on computer clusters, followed by machine learning classification, and an introduction to graph analytics. This part closes with a concise introduction to data core-sets that let big data problems be amenable to tiny data problems. Exercises are included at the end of each chapter in order for students to practice the concepts learned, and a final section contains an overall exam which allows them to evaluate how well they have assimilated the material covered in the book.
