Na wielu forach internetowych znajdziemy wpisy o tematyce: Pomocy! Mój laptop nie działa! Co robić ! Niniejsza publikacja zawiera wskazówki pozwalające na samodzielną diagnostykę, a w wielu przypadkach także sposoby naprawy nie wymagające specjalistycznego sprzętu. Nie znajdziesz tu porad typu „włóż płytę do piekarnika”, „potraktuj chip opalarką lub palnikiem”. Tego typu metody popularne np. na YouTube często powodują nieodwracalne uszkodzenia płyty głównej. Nawet jeśli taka „naprawa” przyniesie skutek – będzie on krótkotrwały. Nie wszystkie naprawy mogą być wykonywane bez specjalistycznego sprzętu. Często jednak wystarczą podstawowe narzędzia. W niniejszej publikacji omawiane będą przede wszystkim takie przypadki. Usterki płyty głównej zostały szerzej omówione w ebooku: „Diagnostyka i naprawa płyt głównych laptopów. Podstawy, metody, przykłady”. Osoby zainteresowane tym tematem zapraszam do lektury. Dla kogo przeznaczona jest ta książka? Zarówno dla osób chcących poznać podstawy budowy, diagnostyki i naprawy laptopów, jak i rozwiązać konkretny problem ze swoim laptopem.

SAP Business ONE brings the power of the SAP ERP platform to small and mid-size companies. It offers fast-growing companies the same ERP capabilities used in world-wide conglomerates and major corporations. SAP Business ONE is powerful, and to fully harness it takes careful planning.This book will provide you with a guide to install and implement SAP B1 in your business. It starts with the basic tasks of installing and configuring, but moves at a fast pace and goes on to cover topics such as advanced CRM, e-commerce, and modern Distribution Center configurations for inventory optimization and Warehouse Management.The book is divided into two main sections. The case study starts out in section one with an ad-hoc implementation of a simple Lemonade Stand business. This section is focused on getting SAP B1 up and running quickly. In the second section the Ad-Hoc Implementation is taken to the next level , and we professionally expand this idea and develop a Beverage Distribution Center with outsourced production. This includes advanced inventory optimization. The workflow is optimized using existing functionality and also using Add-Ons to expand the standard functionality and transform the generic SAP Business ONE business engine into an Industry Solution.The book is full of examples with detailed step-by-step explanations. We will be implementing a complete SAP Business System including add-ons as part of a case study.Finally we connect SAP to the Web and introduce a solution that presents SAP features in a web interface with real-time integration. The book is completed with a chapter focusing on growth. Franchise architecture for SAP Business ONE is introduced and applied to the case study to help you learn how to get started with this.Each chapter has a section that assists you with applying knowledge for your own project.

Xcelsius 2008 was recently included in SAP’s BusinessObjects 4.0 family, rebranding “Xcelsius Enterprise” as “SAP BusinessObjects Dashboards 4.0”. With features like flexible design and what-if scenarios, the powerful dashboarding software allows enterprises to make business decisions at a glance, and this book allows you to go far beyond the basics of these techniques. This cookbook full of practical and applicable recipes will enable you to use the full latest capabilities of Dashboard Design to visually transform your business data. A wide range of recipes will equip you with the knowledge and confidence to perform tasks like configuring charts, creating drill- downs, making component colors dynamic, using alerts in maps, building pop-up screens, setting up What-If scenarios, and many more.The recipes begin by covering best practices for using the Dashboard Design spreadsheet, the data-model, and the connection with the components on the canvas, later moving on to some from-the-trenches tricks for using Excel within Dashboard Design. The book then guides you through the exploration of various data visualization components and dashboard interactivity, as well as offering recipes on using alerts, dashboard connectivity, and making the most of the aesthetics of the dashboard. Finally, the recipes conclude by considering the most important add-ons available for Dashboard Design and enabling you to perform relevant and useful tasks straight away.
Scala Design Patterns. Write efficient, clean, and reusable code with Scala
Ivan Nikolov
Scala has become increasingly popular in many different IT sectors. The language is exceptionally feature-rich which helps developers write less code and get faster results. Design patterns make developer’s lives easier by helping them write great software that is easy to maintain, runs efficiently and is valuable to the company or people concerned.You will learn about the various features of Scala and be able to apply well-known, industry-proven design patterns in your work. The book starts off by focusing on some of the most interesting features of Scala while using practical real-world examples. We will also cover the popular Gang of Four design patterns and show you how to incorporate functional patterns effectively. By the end of this book, you will have enough knowledge and understanding to quickly assess problems and come up with elegant solutions.

Scala is a statically typed, Java Virtual Machine (JVM)-based language with strong support for functional programming. There exist libraries for Scala that cover a range of common scientific computing tasks – from linear algebra and numerical algorithms to convenient and safe parallelization to powerful plotting facilities. Learning to use these to perform common scientific tasks will allow you to write programs that are both fast and easy to write and maintain.We will start by discussing the advantages of using Scala over other scientific computing platforms. You will discover Scala packages that provide the functionality you have come to expect when writing scientific software. We will explore using Scala's Breeze library for linear algebra, optimization, and signal processing. We will then proceed to the Saddle library for data analysis. If you have experience in R or with Python's popular pandas library you will learn how to translate those skills to Saddle. If you are new to data analysis, you will learn basic concepts of Saddle as well. Well will explore the numerical computing environment called ScalaLab. It comes bundled with a lot of scientific software readily available. We will use it for interactive computing, data analysis, and visualization. In the following chapters, we will explore using Scala's powerful parallel collections for safe and convenient parallel programming. Topics such as the Akka concurrency framework will be covered. Finally, you will learn about multivariate data visualization and how to produce professional-looking plots in Scala easily. After reading the book, you should have more than enough information on how to start using Scala as your scientific computing platform

If you have the imaginative power to design complex multimedia projects but can't adapt to programming languages, then Scratch 1.4: Beginner's Guide is the book for you. Imagine how good you'll feel when you drag-and-drop your way to interactive games, stories, graphic artwork, computer animations, and much more using Scratch even if you have never programmed before.This book provides teachers, parents, and new programmers with a guided tour of Scratch's features by creating projects that can be shared, remixed, and improved upon in your own lesson plans. Soon you will be creating games, stories, and animations by snapping blocks of code together.When you program you solve problems. In order to solve problems, you think, take action, and reflect upon your efforts. Scratch teaches you to program using a fun, accessible environment that's as easy as dragging and dropping blocks from one part of the screen to another.In this book you will program games, stories, and animations using hands-on examples that get you thinking and tinkering. For each project, you start with a series of steps to build something. Then you pause to put our actions into context so that you can relate our code to the actions on Scratch's stage. Throughout each chapter, you'll encounter challenges that encourage you to experiment and learn.One of the things you're really going to love is that, as you begin working through the examples in the book, you won't be able to stop your imagination and the ideas will stream as fast as you can think of them. Write them down. You'll quickly realize there are a lot of young minds in your home, classroom, or community group that could benefit from Scratch's friendly face. Teach them, please.
