Le contr le de gestion du SI
Les systèmes d’information sont au cœur de nos organisations. Ils interviennent dans tous les métiers de l’entreprise et ont par conséquent un impact fort sur sa compétitivité et sa rentabilité. Or l’informatique est devenue en quelques années la fonction la plus complexe à gérer de l’entreprise. Le but de cet ouvrage est de doter les DSI de méthodes et d’outils de gestion adaptés pour les aider à dépasser la seule logique des coûts et à appréhender la création de valeur pour l’entreprise. Les différents modèles de gestion (centres de coûts, centres de profit, centres de valeurs...) sont expliqués en détail. A l’instar de la gestion de portefeuilles de projets, beaucoup de méthodes et d’outils qui avaient été développés pour l’informatique sont ensuite devenus des références pour les autres métiers de l’entreprise.
Best-selling author and popular speaker Garr Reynolds is back in this newly revised edition of his classic, best-selling book, Presentation Zen, in which he showed readers there is a better way to reach the audience through simplicity and storytelling, and gave them the tools to confidently design and deliver successful presentations. In this new edition, Garr gives his readers new, fresh examples to draw inspiration from, with a whole new chapter for those who present on more technical and educational topics based on techniques used by many presenters who give high-level talks at TED and other powerhouse events. Whether the reader is in research, technology, business, or education–this book will show them how to take what could look like a really dry presenation and reinvigorate the material in totally fresh (and sometimes interactive!) ways that will make it memorable and resonate with the audience. Staying true to the mission of the first), Garr combines solid principles of design with the tenets of Zen simplicity to help readers along the path to simpler, more effective presentations that will be appreciated, remembered, and best of all, acted upon.
Pervasive Information Systems
Today's ubiquitous computing technology is imbedded in everyday objects from cars to clothes to shipping containers, whose location, context, and state can be monitored, instantly processed, and acted upon. This new volume in the "Advances in Management Information Systems" series provides an in-depth review of the state-of-the-art practices and research opportunities in a new era where information technology resides in physical space. Written for both scholars and practitioners, "Pervasive Information Systems" is organized into three sections, each investigating a distinct part of the subject. Part I focuses on the design challenges of Pervasive Information Systems (PS), and discusses issues relating to the coordination of PS through middleware structures as well as issues related to the efficient deployment of PS. Part II discusses the challenges and limitations of deploying pervasive technologies to support domestic, corporate, and public systems. Part III presents two emerging research fields of PS - design for aesthetics and PS evaluation.

Dashboarding and Reporting with Power Pivot and Excel
Microsoft’s revolutionary Power Pivot is a tool that allows users to create and transform data into reports and dashboards in new and much more powerful ways using the most-used analytical tool in the world: Excel. This book, written by a member of Microsoft’s Power Pivot team, provides a practical step by step guide on creating a financial dashboard. The book covers in detail how to combine and shape the relevant data, build the dashboard in Excel, providing layout and design tips and tricks, prepare the model to work with fiscal dates, and show values used in many financial reports, including year-to-date, variance-to-target, percentage-of-total, and running totals reports. Accessibly written, this book offers readers a practical, real-world scenario and can be used as a day-to-day reference. Though the guide focuses on Power Pivot for Excel 2010, a chapter that discusses Power View—compatible with Excel 2013— and Power BI is also included.
RESTful Web APIs
The popularity of REST in recent years has led to tremendous growth in almost-RESTful APIs that don’t include many of the architecture’s benefits. With this practical guide, you’ll learn what it takes to design usable REST APIs that evolve over time. By focusing on solutions that cross a variety of domains, this book shows you how to create powerful and secure applications, using the tools designed for the world’s most successful distributed computing system: the World Wide Web. You’ll explore the concepts behind REST, learn different strategies for creating hypermedia-based APIs, and then put everything together with a step-by-step guide to designing a RESTful Web API. Examine API design strategies, including the collection pattern and pure hypermedia Understand how hypermedia ties representations together into a coherent API Discover how XMDP and ALPS profile formats can help you meet the Web API "semantic challenge" Learn close to two-dozen standardized hypermedia data formats Apply best practices for using HTTP in API implementations Create Web APIs with the JSON-LD standard and other the Linked Data approaches Understand the CoAP protocol for using REST in embedded systems

The Art of Deception
The world's most infamous hacker offers an insider's view of the low-tech threats to high-tech security Kevin Mitnick's exploits as a cyber-desperado and fugitive form one of the most exhaustive FBI manhunts in history and have spawned dozens of articles, books, films, and documentaries. Since his release from federal prison, in 1998, Mitnick has turned his life around and established himself as one of the most sought-after computer security experts worldwide. Now, in The Art of Deception, the world's most notorious hacker gives new meaning to the old adage, "It takes a thief to catch a thief." Focusing on the human factors involved with information security, Mitnick explains why all the firewalls and encryption protocols in the world will never be enough to stop a savvy grifter intent on rifling a corporate database or an irate employee determined to crash a system. With the help of many fascinating true stories of successful attacks on business and government, he illustrates just how susceptible even the most locked-down information systems are to a slick con artist impersonating an IRS agent. Narrating from the points of view of both the attacker and the victims, he explains why each attack was so successful and how it could have been prevented in an engaging and highly readable style reminiscent of a true-crime novel. And, perhaps most importantly, Mitnick offers advice for preventing these types of social engineering hacks through security protocols, training programs, and manuals that address the human element of security.
Confronting the Challenges of Participatory Culture
Many teens today who use the Internet are actively involved in participatory cultures -- joining online communities (Facebook, message boards, game clans), producing creative work in new forms (digital sampling, modding, fan videomaking, fan fiction), working in teams to complete tasks and develop new knowledge (as in Wikipedia), and shaping the flow of media (as in blogging or podcasting). A growing body of scholarship suggests potential benefits of these activities, including opportunities for peer-to-peer learning, development of skills useful in the modern workplace, and a more empowered conception of citizenship. Some argue that young people pick up these key skills and competencies on their own by interacting with popular culture; but the problems of unequal access, lack of media transparency, and the breakdown of traditional forms of socialization and professional training suggest a role for policy and pedagogical intervention.This report aims to shift the conversation about the "digital divide" from questions about access to technology to questions about access to opportunities for involvement in participatory culture and how to provide all young people with the chance to develop the cultural competencies and social skills needed. Fostering these skills, the authors argue, requires a systemic approach to media education; schools, afterschool programs, and parents all have distinctive roles to play.The John D. and Catherine T.
