Das Praxisbuch stellt die Windows PowerShell in der aktuellsten Version als vielseitiges Werkzeug für die Administration von Windows Server 2008 R2/2012/2012 R2 und Windows Server 2016 vor. Es richtet sich an Administratoren, die sich bereits mit der PowerShell auskennen und ihr Wissen an aktuellen Themen vertiefen wollen. Es beschreibt zunächst die Kernkonzepte der PowerShell wie Typen, Objekte, stellt die mit der Version 5.0 dazu gekommenen Klassen vor, und gibt einen Überblick über Advanced Functions und Module. Danach werden fortgeschrittenere Themen wie Debuggen, die Umwandlung von Texten in Objekte und das Testen von Skripten mit Pester vorgestellt. Ein weiterer Schwerpunkt ist das Thema DevOps, das bei der PowerShell zum einen über die Desired State Configuration (DSC) adressiert wird, zum anderen über moderne Bereitstellungsmechanismen von Modulen und Ressourcen im Rahmen einer Release-Pipeline. Anwendungsorientierte Themen wie die Administration eines Active Directory, Azure-Dienste, Empfehlungen für gute Skripte und ein wenig Spaß, der beim Arbeiten mit der PowerShell, wie bei jeder Shell auch, dazu gehören sollte, runden das Buch ab. Zielgruppe Windows-Administratoren.

Software maintenance work is often considered a dauntingly rigid activity – this book proves the opposite: it demands high levels of creativity and thinking outside the box. Highlighting the creative aspects of software maintenance and combining analytical and systems thinking in a holistic manner, the book motivates readers not to blithely follow the beaten tracks of “technical rationality”. It delivers the content in a pragmatic fashion using case studies which are woven into long running story lines. The book is organized in four parts, which can be read in any order, except for the first chapter, which introduces software maintenance and evolution and presents a number of case studies of software failures. The “Introduction to Key Concepts” briefly introduces the major elements of software maintenance by highlighting various core concepts that are vital in order to see the forest for the trees. Each such concept is illustrated with a worked example. Next, the “Forward Engineering” part debunks the myth that being fast and successful during initial development is all that matters. To this end, two categories of forward engineering are considered: an inept initial project with a multitude of hard evolutionary phases and an effective initial project with multiple straightforward future increments. “Reengineering and Reverse Engineering” shows the difficulties of dealing with a typical legacy system, and tackles tasks such as retrofitting tests, documenting a system, restructuring a system to make it amenable for further improvements, etc. Lastly, the “DevOps” section focuses on the importance and benefits of crossing the development versus operation chasm and demonstrates how the DevOps paradigm can turn a loosely coupled design into a loosely deployable solution. The book is a valuable resource for readers familiar with the Java programming language, and with a basic understanding and/or experience of software construction and testing. Packed with examples for every elaborated concept, it offers complementary material for existing courses and is useful for students and professionals alike.

This book introduces readers to the fundamentals of creating presentation graphics using R, based on 100 detailed and complete scripts. It shows how bar and column charts, population pyramids, Lorenz curves, box plots, scatter plots, time series, radial polygons, Gantt charts, heat maps, bump charts, mosaic and balloon charts, and a series of different thematic map types can be created using R’s Base Graphics System. Every example uses real data and includes step-by-step explanations of the figures and their programming. The open source software R is an established standard and a powerful tool for various visualizing applications, integrating nearly all technologies relevant for data visualization. The basic software, enhanced by more than 7000 extension packs currently freely available, is intensively used by organizations including Google, Facebook and the CIA. The book serves as a comprehensive reference guide to a broad variety of applications in various fields. This book is intended for all kinds of R users, ranging from experts, for whom especially the example codes are particularly useful, to beginners, who will find the finished graphics most helpful in learning what R can actually deliver. Features and Benefits Offers a comprehensive introduction to creating presentation graphics with R Presents the complete code of 100 examples from various fields Includes step-by-step explanations of the programming of figures, based on real data.

This invaluable textbook presents a comprehensive introduction to modern competitive programming. The text highlights how competitive programming has proven to be an excellent way to learn algorithms, by encouraging the design of algorithms that actually work, stimulating the improvement of programming and debugging skills, and reinforcing the type of thinking required to solve problems in a competitive setting. The book contains many “folklore” algorithm design tricks that are known by experienced competitive programmers, yet which have previously only been formally discussed in online forums and blog posts. Topics and features: Reviews the features of the C++ programming language, and describes how to create efficient algorithms that can quickly process large data sets Discusses sorting algorithms and binary search, and examines a selection of data structures of the C++ standard library Introduces the algorithm design technique of dynamic programming, and investigates elementary graph algorithms Covers such advanced algorithm design topics as bit-parallelism and amortized analysis, and presents a focus on efficiently processing array range queries Surveys specialized algorithms for trees, and discusses the mathematical topics that are relevant in competitive programming Examines advanced graph techniques, geometric algorithms, and string techniques Describes a selection of more advanced topics, including square root algorithms and dynamic programming optimization This easy-to-follow guide is an ideal reference for all students wishing to learn algorithms, and practice for programming contests. Knowledge of the basics of programming is assumed, but previous background in algorithm design or programming contests is not necessary. Due to the broad range of topics covered at various levels of difficulty, this book is suitable for both beginners and more experienced readers. Dr. Antti Laaksonen has worked as a teacher and researcher at the University of Helsinki and Aalto University, Finland. He has served as one of the organizers of the Finnish Olympiad in Informatics since 2008, and as the Scientific Chair of the Baltic Olympiad in Informatics in 2016. He has also coached and led the Finnish team at several international programming contests, including the International Olympiad in Informatics 2009–2016, and has established experience in teaching programming and algorithms.
