Now updated in line with the 2011 syllabus, this quick-reference revision guide has been designed to help students prepare for their foundation exam. It is also a key reference aid for managers, practitioners, vendors and consultants in the workplace and while travelling. This handbook provides an introduction to the ITIL service lifecycle model and an overview of the ITIL qualification structure. It contains a chapter on each of the components of the lifecycle: service strategy, service design, service transition, service operation and continual service improvement.
This book distils into a single coherent handbook all the essentials of process automation at a depth sufficient for most practical purposes. No other book covers the gap between the theory and practice of control systems so comprehensively.
Key Features: · Example-rich guide · Step-by-step guide · Move from single-machine to massive cluster Readers should have intermediate skills in Java or Scala. No previous machine learning experience is required.
Fundamentally, computers just deal with numbers. They store letters and other characters by assigning a number for each one. There are hundreds of different encoding systems for mapping characters to numbers, but Unicode promises a single mapping. Unicode enables a single software product or website to be targeted across multiple platforms, languages and countries without re-engineering. It´s no wonder that industry giants like Apple, Hewlett-Packard, IBM andMicrosoft have all adopted Unicode. Containing everything you need to understand Unicode, this comprehensive reference from O´Reilly takes you on a detailed guide through the complex character world. For starters, it explains how to identify and classify characters - whether they´re common, uncommon, or exotic. It then shows you how to type them, utilize their properties, and process character data in a robust manner. The book is broken up into three distinct parts. The first few chapters provide you with a tutorial presentation of Unicode and character data. It gives you a firm grasp of the terminology you need to reference various components, including character sets, fonts and encodings, glyphs and character repertoires. The middle section offers more detailed information about using Unicode and other character codes. It explains the principles and methods of defining character codes, describes some of the widely used codes, and presents code conversion techniques. It also discusses properties of characters, collation and sorting, line breaking rules and Unicode encodings. The final four chapters cover more advanced material, such as programming to support Unicode. You simply can´t afford to be without the nuggets of valuable information detailed in Unicode Explained.
This book provides a readable and elegant presentation of the principles of anomaly detection,providing an easy introduction for newcomers to the field. A large number of algorithms are succinctly described, along with a presentation of their strengths and weaknesses. The authors also cover algorithms that address different kinds of problems of interest with single and multiple time series data and multi-dimensional data. New ensemble anomaly detection algorithms are described, utilizing the benefits provided by diverse algorithms, each of which work well on some kinds of data. With advancements in technology and the extensive use of the internet as a medium for communications and commerce, there has been a tremendous increase in the threats faced by individuals and organizations from attackers and criminal entities. Variations in the observable behaviors of individuals (from others and from their own past behaviors) have been found to be useful in predicting potential problems of various kinds. Hence computer scientists and statisticians have been conducting research on automatically identifying anomalies in large datasets. This book will primarily target practitioners and researchers who are newcomers to the area of modern anomaly detection techniques. Advanced-level students in computer science will also find this book helpful with their studies.
With a growing number of internet-connected devices DDoS attacks become stronger while link speeds of up to 100 Gbit/s reduce the time that is available for handling a single data packet. Linux features a general-purpose networking stack that is too slow for handling high-profile packet floods. A different solution is needed to successfully mitigate DDoS attacks; so-called kernel bypass techniques are commonly used for this purpose, such as the DPDK framework. Recently (as of Linux 4.8) an emerging alternative, which doesn´t bypass the kernel, called XDP has been available. This paper evaluates performance of XDP with Intel hardware and compares it to DPDK at a workload that is relevant to the use-case of DDoS mitigation.
Electronic voting (e-voting) is a symbol of modern democracy activities. Due to the high ballot privacy and verifiability, e-voting system has been booming in recent years. Existing electronic voting systems all suffer from a serious design flaw: They are centralized by design, meaning there is a single supplier that controls the code base, the database, and the system outputs while also supplying the monitoring tools to verify the result. The lack of an independently verifiable output makes it difficult for these centralized systems to acquire the trustworthiness required by voters, thus potentially limiting voter participation, or cast doubt upon the published output of an election. To provide an immutable, verifiable and secure online voting system we intend to leverage the availability of the Blockchain as a secure transaction database. From this public ledger, voters will be able to independently audit the inclusion of their vote, and the outcome of the election as a whole, while being sure that the results cannot be changed due to the immutability of the Blockchain.
