    We look at how to set up your spreadsheet, getting data into Excel, formatting your spreadsheet, a bit of display management and how to print and share your spreadsheets. Learn Excel Visually The idea of these short handy bite-size books is to provide you with what I have found to be most useful elements of Excel within my day-to-day work and life. I don’t tell you about all the bells and whistles – just what you need on a daily basis. These eBooks are suitable for anyone who is looking to learn Excel and wants to increase their productivity and efficiency, both at work and home. Please bear in mind I don’t cover all functionality of all areas, the point is that I strip out anything that’s not useful and only highlight the functionality that I believe is useful on a daily basis. Don’t buy a huge textbook which you’ll never fully read, pick an eBook which is most relevant to your current learning, read it, apply it and then get on with your day.

    Because almost every aspect of an enterprise is now dependent on technology, the focus of IT security must shift from locking down assets to enabling the business while managing and surviving risk. This compact book discusses business risk from a broader perspective, including privacy and regulatory considerations. It describes the increasing number of threats and vulnerabilities, but also offers strategies for developing solutions. These include discussions of how enterprises can take advantage of new and emerging technologies—such as social media and the huge proliferation of Internet-enabled devices—while minimizing risk. With ApressOpen, content is freely available through multiple online distribution channels and electronic formats with the goal of disseminating professionally edited and technically reviewed content to the worldwide community. Here are some of the responses from reviewers of this exceptional work: “Managing Risk and Information Security is a perceptive, balanced, and often thought-provoking exploration of evolving information risk and security challenges within a business context.  Harkins clearly connects the needed, but often-overlooked linkage and dialog between the business and technical worlds and offers actionable strategies.   The book contains eye-opening security insights that are easily understood, even by the curious layman.” Fred Wettling, Bechtel Fellow, IS&T Ethics & Compliance Officer, Bechtel     “As disruptive technology innovations and escalating cyber threats continue to create enormous information security challenges, Managing Risk and Information Security: Protect to Enable provides a much-needed perspective. This book compels information security professionals to think differently about concepts of risk management in order to be more effective. The specific and practical guidance offers a fast-track formula for developing information security strategies which are lock-step with business priorities.” Laura Robinson, Principal, Robinson Insight Chair, Security for Business Innovation Council (SBIC) Program Director, Executive Security Action Forum (ESAF) “The mandate of the information security function is being completely rewritten. Unfortunately most heads of security haven’t picked up on the change, impeding their companies’ agility and ability to innovate. This book makes the case for why security needs to change, and shows how to get started. It will be regarded as marking the turning point in information security for years to come.” Dr. Jeremy Bergsman, Practice Manager, CEB     “The world we are responsible to protect is changing dramatically and at an accelerating pace. Technology is pervasive in virtually every aspect of our lives. Clouds, virtualization and mobile are redefining computing – and they are just the beginning of what is to come. Your security perimeter is defined by wherever your information and people happen to be.

    In Turing’s Cathedral, George Dyson focuses on a small group of men and women, led by John von Neumann at the Institute for Advanced Study in Princeton, New Jersey, who built one of the first computers to realize Alan Turing’s vision of a Universal Machine. Their work would break the distinction between numbers that mean things and numbers that do things—and our universe would never be the same. Using five kilobytes of memory (the amount allocated to displaying the cursor on a computer desktop of today), they achieved unprecedented success in both weather prediction and nuclear weapons design, while tackling, in their spare time, problems ranging from the evolution of viruses to the evolution of stars. Dyson’s account, both historic and prophetic, sheds important new light on how the digital universe exploded in the aftermath of World War II. The proliferation of both codes and machines was paralleled by two historic developments: the decoding of self-replicating sequences in biology and the invention of the hydrogen bomb. It’s no coincidence that the most destructive and the most constructive of human inventions appeared at exactly the same time.  How did code take over the world? In retracing how Alan Turing’s one-dimensional model became John von Neumann’s two-dimensional implementation, Turing’s Cathedral offers a series of provocative suggestions as to where the digital universe, now fully three-dimensional, may be heading next.

    Their achievements, rich culture and craftsmanship contributed greatly to our world today, and their explorations helped make up the boundaries of nations. The Vikings: Raiders, Explorers, and Seafaring Warriors by author Lance Hightower will give you a glimpse of the battles that raged for more than 300 years, sparked by the cultural and religious differences that were the trigger for warring with the Franks, England and Ireland, and for trade and exploration into the Muslim empire, the Byzantine Empire, as far as Russia, Spain and North America.They came from Sweden, Norway and Denmark, not as one army, but as separate tribes who assaulted their way through Christendom as retaliation for the destruction of their holy icon. They came from the sea in a way that ingeniously allowed them to go where no conventional ship dared, and they were able to navigate waters without benefit of the sun to guide them. They used boats that made ship-building history – light, fast, and equally efficient in shallow rivers and mighty oceans.They terrorized, traded, bartered, took slaves, colonized, fought and died all in the name of Odin, god of the battle-slain. Perhaps in the end, they fought more for territory and riches than principle, but the history of the Vikings will always remain as one of the most enthralling of all Ages, where honor was crucial, death on the battlefield was preferred to idleness, and the stormy pantheon of their gods still held the greatest influence in their lives.The brilliant sagas come to life with snippets of modern translations, told like tales of old should be told, with dread, heroics and excitement. Lance Hightower combines his own expertise with the latest archeological findings and information given to us from ancient text to present a first-rate portrayal of the Vikings in an easy-to-read format that is a refreshing change from the usual dry delivery of history.

    Their discussion ranges from the history of the field's intellectual foundations to the most recent developments and applications.Reinforcement learning, one of the most active research areas in artificial intelligence, is a computational approach to learning whereby an agent tries to maximize the total amount of reward it receives when interacting with a complex, uncertain environment. In Reinforcement Learning, Richard Sutton and Andrew Barto provide a clear and simple account of the key ideas and algorithms of reinforcement learning. Their discussion ranges from the history of the field's intellectual foundations to the most recent developments and applications. The only necessary mathematical background is familiarity with elementary concepts of probability.The book is divided into three parts. Part I defines the reinforcement learning problem in terms of Markov decision processes. Part II provides basic solution methods: dynamic programming, Monte Carlo methods, and temporal-difference learning. Part III presents a unified view of the solution methods and incorporates artificial neural networks, eligibility traces, and planning; the two final chapters present case studies and consider the future of reinforcement learning.
