System Performance Tuning: Help for Unix Administrators
by Mike Loukides Gian-Paolo D. MusumeciSystem Performance Tuning answers one of the most fundamental questions you can ask about your computer: How can I get it to do more work without buying more hardware? In the current economic downturn, performance tuning takes on a new importance. It allows system administrators to make the best use of existing systems and minimize the purchase of new equipment. Well-tuned systems save money and time that would otherwise be wasted dealing with slowdowns and errors. Performance tuning always involves compromises; unless system administrators know what the compromises are, they can't make intelligent decisions.Tuning is an essential skill for system administrators who face the problem of adapting the speed of a computer system to the speed requirements imposed by the real world. It requires a detailed understanding of the inner workings of the computer and its architecture. System Performance Tuning covers two distinct areas: performance tuning, or the art of increasing performance for a specific application, and capacity planning, or deciding what hardware best fulfills a given role. Underpinning both subjects is the science of computer architecture. This book focuses on the operating system, the underlying hardware, and their interactions. Topics covered include:Real and perceived performance problems, introducing capacity planning and performance monitoring (highlighting their strengths and weaknesses). An integrated description of all the major tools at a system administrator's disposal for tracking down system performance problems. Background on modern memory handling techniques, including the memory-caching filesystem implementations in Solaris and AIX. Updated sections on memory conservation and computing memory requirements. In depth discussion of disk interfaces, bandwidth capacity considerations, and RAID systems. Comprehensive discussion of NFS and greatly expanded discussion of networking. Workload management and code tuning. Special topics such as tuning Web servers for various types of content delivery and developments in cross-machine parallel computing For system administrators who want a hands-on introduction to system performance, this is the book to recommend.
The Evolution of Data Products
by Mike LoukidesThis report examines the important shifts in data products. Drawing from diverse examples, including iTunes, Google's self-driving car, and patient monitoring, author Mike Loukides explores the "disappearance" of data, the power of combining data, and the difference between discovery and recommendation. Looking ahead, the analysis finds the real changes in our lives will come from products and companies that reveal data results, not the data itself.
What Is Data Science?
by Mike LoukidesWe've all heard it: according to Hal Varian, statistics is the next sexy job. Five years ago, in What is Web 2.0, Tim O'Reilly said that "data is the next Intel Inside." But what does that statement mean? Why do we suddenly care about statistics and about data? This report examines the many sides of data science -- the technologies, the companies and the unique skill sets.The web is full of "data-driven apps." Almost any e-commerce application is a data-driven application. There's a database behind a web front end, and middleware that talks to a number of other databases and data services (credit card processing companies, banks, and so on). But merely using data isn't really what we mean by "data science." A data application acquires its value from the data itself, and creates more data as a result. It's not just an application with data; it's a data product. Data science enables the creation of data products.
What is DevOps?
by Mike LoukidesHave we entered the age of NoOps infrastructures? Hardly. Old-style system administrators may be disappearing in the face of automation and cloud computing, but operations have become more significant than ever. As this O’Reilly Radar Report explains, we’re moving into a more complex arrangement known as "DevOps."Mike Loukides, O’Reilly’s VP of Content Strategy, provides an incisive look into this new world of operations, where IT specialists are becoming part of the development team. In an environment with thousands of servers, these specialists now write the code that maintains the infrastructure. Even applications that run in the cloud have to be resilient and fault tolerant, need to be monitored, and must adjust to huge swings in load. That was underscored by Amazon’s EBS outage last year.From the discussions at O’Reilly’s Velocity Conference, it’s evident that many operations specialists are quickly adapting to the DevOps reality. But as a whole, the industry has just scratched the surface. This report tells you why.

CALL Dimensions: Options and Issues in Computer-Assisted Language Learning (ESL & Applied Linguistics Professional Series)
by Glenn Stockwell Mike LevyThis volume gives language teachers, software designers, and researchers who wish to use technology in second or foreign language education the information they need to absorb what has been achieved so far and to make sense of it. It is designed to enable the kind of critical reading of a substantial literature that leads to a balanced and detailed knowledge of the field. Chapter by chapter, the book builds, through description, analysis, examples, and discussion, a detailed picture of modern CALL. In this book, the label “CALL” is interpreted broadly to include technology-enhanced language learning, Web-enhanced language learning, and information and communication technologies for language learning. The work is distinguished by its attention to a range of languages rather than just English. The authors first set the scene and introduce major areas of interest and growth in CALL, and then look in depth at seven important dimensions: design, evaluation, computer-mediated communication, theory, research, practice, and technology. Chapters on each of these topics include a description that reviews the recent literature, identifies themes, and presents representative projects that illustrate the dimension, followed by a discussion that provides in-depth analysis, and a conclusion offering suggestions for further work. Detailed references and links connect the description and discussion with original works and primary sources so the reader can follow up easily on areas of personal interest. Two concluding chapters discuss how the various dimensions might be brought together, the first from a practical point of view, the second with a view to the development of CALL as a whole.

Chinese Social Media: Social, Cultural, and Political Implications (Routledge Research in Digital Media and Culture in Asia)
by Katie Ellis Mike Kent Jian XuThis book brings together scholars from a variety of disciplines to address critical perspectives on Chinese language social media, internationalizing the state of social media studies beyond the Anglophone paradigm. The collection focuses on the intersections between Chinese language social media and disability, celebrity, sexuality, interpersonal communication, charity, diaspora, public health, political activism and non-governmental organisations (NGOs). The book is not only rich in its theoretical perspectives but also in its methodologies. Contributors use both qualitative and quantitative methods to study Chinese social media and its social–cultural–political implications, such as case studies, in-depth interviews, participatory observations, discourse analysis, content analysis and data mining.
Disability and New Media (Routledge Studies in New Media and Cyberculture)
by Katie Ellis Mike KentDisability and New Media examines how digital design is triggering disability when it could be a solution. Video and animation now play a prominent role in the World Wide Web and new types of protocols have been developed to accommodate this increasing complexity. However, as this has happened, the potential for individual users to control how the content is displayed has been diminished. Accessibility choices are often portrayed as merely technical decisions but they are highly political and betray a disturbing trend of ableist assumption that serve to exclude people with disability. It has been argued that the Internet will not be fully accessible until disability is considered a cultural identity in the same way that class, gender and sexuality are. Kent and Ellis build on this notion using more recent Web 2.0 phenomena, social networking sites, virtual worlds and file sharing. Many of the studies on disability and the web have focused on the early web, prior to the development of social networking applications such as Facebook, YouTube and Second Life. This book discusses an array of such applications that have grown within and alongside Web 2.0, and analyzes how they both prevent and embrace the inclusion of people with disability.

The Fundamentals of Tabletop Miniatures Game Design: A Designer’s Handbook
by Mike Hutchinson Glenn FordThis book presents a much-needed framework for the critical examination of miniatures games and their design. It provides the reader with both a conceptual model for understanding how these games work as well as a toolbox of mechanical approaches to achieving a range of design outcomes and assessing the fit of any given approach within a specific design.Though dating back to the 1820s, tabletop miniatures games have been little explored critically and lack a conceptual vocabulary for their discussion. Active practitioners in the miniature games design community, Glenn Ford and Mike Hutchinson explore what defines these games, proposing the term ‘non-discrete miniatures games’ to encapsulate the essence of these open and immersive hobby gaming experiences. Discarding the term ‘wargame’, they argue against limiting conceptions of these games to direct armed conflict, and champion their diverse narrative potential.The book provides a fresh conceptual framework for miniatures games, abstracting the concepts of positioning and moving markers non-discretely across scale-modelled environments into inclusive and generalised terminology, untethering them from their roots as military simulations and providing the foundations for a fresh consideration of miniatures games design.Written for game designers, and with a foreword by Gav Thorpe, The Fundamentals of Tabletop Miniatures Game Design is a handbook for those that wish to design better miniatures games.

Autonomy Requirements Engineering for Space Missions (NASA Monographs in Systems and Software Engineering)
by Mike Hinchey Emil VassevAdvanced space exploration is performed by unmanned missions with integrated autonomy in both flight and ground systems. Risk and feasibility are major factors supporting the use of unmanned craft and the use of automation and robotic technologies where possible. Autonomy in space helps to increase the amount of science data returned from missions, perform new science, and reduce mission costs. Elicitation and expression of autonomy requirements is one of the most significant challenges the autonomous spacecraft engineers need to overcome today. This book discusses the Autonomy Requirements Engineering (ARE) approach, intended to help software engineers properly elicit, express, verify, and validate autonomy requirements. Moreover, a comprehensive state-of-the-art of software engineering for aerospace is presented to outline the problems handled by ARE along with a proof-of-concept case study on the ESA's BepiColombo Mission demonstrating the ARE's ability to handle autonomy requirements.
Conquering Complexity
by Mike Hinchey Lorcan CoyleSoftware has long been perceived as complex, at least within Software Engineering circles. We have been living in a recognised state of crisis since the first NATO Software Engineering conference in 1968. Time and again we have been proven unable to engineer reliable software as easily/cheaply as we imagined. Cost overruns and expensive failures are the norm. The problem is fundamentally one of complexity: software is fundamentally complex because it must be precise. Problems that appear to be specified quite easily in plain language become far more complex when written in a more formal notation, such as computer code. Comparisons with other engineering disciplines are deceptive. One cannot easily increase the factor of safety of software in the same way that one could in building a steel structure, for example. Software is typically built assuming perfection, often without adequate safety nets in case the unthinkable happens. In such circumstances it should not be surprising to find out that (seemingly) minor errors have the potential to cause entire software systems to collapse. The goal of this book is to uncover techniques that will aid in overcoming complexity and enable us to produce reliable, dependable computer systems that will operate as intended, and yet are produced on-time, in budget, and are evolvable, both over time and at run time. We hope that the contributions in this book will aid in understanding the nature of software complexity and provide guidance for the control or avoidance of complexity in the engineering of complex software systems.
