Shareware Heroes is a comprehensive, meticulously researched exploration of an important and too-long overlooked chapter in video game history Shareware Heroes: Independent Games at the Dawn of the Internet takes readers on a journey, from the beginnings of the shareware model in the early 1980s, the origins of the concept, even the name itself, and the rise of shareware's major players – the likes of id Software, Apogee, and Epic MegaGames – through to the significance of shareware for the ‘forgotten’ systems – the Mac, Atari ST, Amiga – when commercial game publishers turned away from them. This book also charts the emergence of commercial shareware distributors like Educorp and the BBS/newsgroup sharing culture. And it explores how shareware developers plugged gaps in the video gaming market by creating games in niche and neglected genres like vertically-scrolling shoot-'em-ups (e.g. Raptor and Tyrian) or racing games (e.g. Wacky Wheels and Skunny Kart) or RPGs (God of Thunder and Realmz), until finally, as the video game market again grew and shifted, and major publishers took control, how the shareware system faded into the background and fell from memory.

The book is aimed at graduate students, researchers, engineers and physicists involved in fluid computations. An up-to-date account is given of the present state of the art of numerical methods employed in computational fluid dynamics. The underlying numerical principles are treated with a fair amount of detail, using elementary methods. Attention is given to the difficulties arising from geometric complexity of the flow domain. Uniform accuracy for singular perturbation problems is studied, pointing the way to accurate computation of flows at high Reynolds number. Unified methods for compressible and incompressible flows are discussed. A treatment of the shallow-water equations is included. A basic introduction is given to efficient iterative solution methods. Many pointers are given to the current literature, facilitating further study.

Influential writings make the case for open access to research, explore its implications, and document the early struggles and successes of the open access movement. Peter Suber has been a leading advocate for open access since 2001 and has worked full time on issues of open access since 2003. As a professor of philosophy during the early days of the internet, he realized its power and potential as a medium for scholarship. As he writes now, “it was like an asteroid crash, fundamentally changing the environment, challenging dinosaurs to adapt, and challenging all of us to figure out whether we were dinosaurs.” When Suber began putting his writings and course materials online for anyone to use for any purpose, he soon experienced the benefits of that wider exposure. In 2001, he started a newsletter—the Free Online Scholarship Newsletter, which later became the SPARC Open Access Newsletter—in which he explored the implications of open access for research and scholarship. This book offers a selection of some of Suber's most significant and influential writings on open access from 2002 to 2010. In these texts, Suber makes the case for open access to research; answers common questions, objections, and misunderstandings; analyzes policy issues; and documents the growth and evolution of open access during its most critical early decade.

Work. Eat. Sleep. Repeat. Work. Eat. Sleep. Repeat. Work. Eat. Sleep. Repeat. Have you ever sat at your desk and asked yourself, why am I here? Is this really all there is? Believe me, it isn't. Over the past three decades, my generation created the enormous machines we call multinational corporations. Today, over half of the largest economies in the world are global businesses - controlled by the few, while impacting the many. Business has the power to change the world. But what if we, as individuals, had the power to change the world of business? We are in the age of the intrapreneur: where mavericks and rebels bring their entrepreneurial prowess to big business, to change it from the inside out and bottom up. The Intrapreneur is the story of my dream to do exactly that and how you can too. For over a decade, I led a team within one of the world’s largest global consulting organisations – a corporate “guerrilla movement” working deep within the system, to try to change the system. Our goals were huge: we wanted to revolutionise the role of business in the aid and development sector and offer our skills and expertise to not-for-profits in parts of the world with greatest need, but least access. This was my dream but, until now, I have never admitted the personal toll that it took on me. It ultimately cost me my job, my health and perhaps even my sanity as I landed myself in a psychiatric hospital for five days and five nights. I had found my purpose, but had I lost my mind? The Intrapreneur is a call to action for a new breed of social activist working within, about to join or completely disillusioned by today’s business world - to be the change you want to see in your company. So my message is a simple one. If you feel that description applies to you, either change company or better still, change the company you’re in – for the better. If we strive to create the organisations we desire to work in, which build the societies we want to live in, then we’ll be helping not only ourselves and our colleagues, but the world as a whole. Join us today.

Computing Handbook, Third Edition: Computer Science and Software Engineering mirrors the modern taxonomy of computer science and software engineering as described by the Association for Computing Machinery (ACM) and the IEEE Computer Society (IEEE-CS). Written by established leading experts and influential young researchers, the first volume of this popular handbook examines the elements involved in designing and implementing software, new areas in which computers are being used, and ways to solve computing problems. The book also explores our current understanding of software engineering and its effect on the practice of software development and the education of software professionals. Like the second volume, this first volume describes what occurs in research laboratories, educational institutions, and public and private organizations to advance the effective development and use of computers and computing in today’s world. Research-level survey articles provide deep insights into the computing discipline, enabling readers to understand the principles and practices that drive computing education, research, and development in the twenty-first century.

The Leibniz Supercomputing Centre (LRZ) and the Bavarian Competence Network for Technical and Scienti?c High Performance Computing (KONWIHR) publish in the present book results of numerical simulations facilitated by the High P- formance Computer System in Bavaria (HLRB II) within the last two years. The papers were presented at the Fourth Joint HLRB and KONWIHR Review and - sult Workshop in Garching on 8th and 9th December 2009, and were selected from all progress reports of projects that use the HLRB II. Similar to the workshop two years ago, the majority of the contributed papers belong to the area of computational ?uid dynamics (CFD), condensed matter physics, astrophysics, chemistry, computer sciences and high-energy physics. We note a considerable increase of the user c- munity in some areas: Compared to 2007, the number of papers increased from 6 to 12 in condensed matter physics and from 2 to 5 in high-energy physics. Bio s- ences contributed only one paper in 2007, but four papers in 2009. This indicates that the area of application of supercomputers is continuously growing and entering new ?elds of research. The year 2007 saw two major events of particular importance for the LRZ. First, after a substantial upgrade with dual-core processors the SGI Altix 4700 superc- puter reached a peak performance of more than 62 Tera?op/s. And second, the n- pro?t organization Gauss Centre for Supercomputing e. V. (GCS) was founded on April 13th.

Galileo Unbound traces the journey that brought us from Galileo's law of free fall to today's geneticists measuring evolutionary drift, entangled quantum particles moving among many worlds, and our lives as trajectories traversing a health space with thousands of dimensions. Remarkably, common themes persist that predict the evolution of species as readily as the orbits of planets or the collapse of stars into black holes. This book tells the history of spaces of expanding dimension and increasing abstraction and how they continue today to give new insight into the physics of complex systems. Galileo published the first modern law of motion, the Law of Fall, that was ideal and simple, laying the foundation upon which Newton built the first theory of dynamics. Early in the twentieth century, geometry became the cause of motion rather than the result when Einstein envisioned the fabric of space-time warped by mass and energy, forcing light rays to bend past the Sun. Possibly more radical was Feynman's dilemma of quantum particles taking all paths at once — setting the stage for the modern fields of quantum field theory and quantum computing. Yet as concepts of motion have evolved, one thing has remained constant, the need to track ever more complex changes and to capture their essence, to find patterns in the chaos as we try to predict and control our world.
