Book SynopsisSometimes only words will do. Graphical user interfaces (GUIs) were a great advance, creating an easy route into computer use for many non-technical users. For complex tasks, though, the interface can become a limitation: blocking off choices, and leaving a circuitous route even for only moderately complicated jobs. (Re-)Enter the command line: the blinking cursor that many thought had faded away in the 1990s. For getting instructions from user to computer - in a clear, quick, and unambiguous form - the command line is often the best way. It never disappeared on UNIX systems, and now, thanks to Raspberry Pi OS on the Raspberry Pi, a new generation is discovering the power of the command line to simplify complex tasks, or instantly carry out simple ones. Master essential skills:Read and write text filesFind & install softwareManage removable storageUse Secure Shell for remote accessCreate Raspberry Pi SD cardsGoing online in the command lineand much, much more. If you're not comfortable when faced with the $ prompt, then don't panic! In this fully updated book, we'll quickly make you feel at home, and able to find your way around the terminal on the Pi, or any other GNU/Linux computer: getting things done, and unlocking the power of the command line. Updated for the latest Raspberry Pi devices and hardware, this book has everything you need to get started.

Book SynopsisUse continuous Integration (CI) and continuous delivery (CD) to improve the speed of software delivery. This book presents a game changer-how to use pipelines to automate the software delivery process. The theories about CI/CD are much the same, but the book covers what the development of pipelines looks like and how testing of pipelines themselves should be performed.Most teams just plunge into coding, without thinking about the CI/CD process itself. Why don''t we use the same development method for pipelines that we use for apps? Pipelines code development undergoes similar stages as application code development, such as requirements analysis, development, testing, implementation, operations, and monitoring. This is the starting point of the book. It describes the current challenges with pipeline development and how this process can be improved and structured. It describes in detail how to design pipelines and shows examples in BPMN 2.0 notation.Table of ContentsChapter 1. The CI/CD pitfallChallenges Chapter 2.

Book SynopsisNew insight in many scientific and engineering fields is unthinkable without the use of numerical simulations running efficiently on modern computers. The faster we get new results, the bigger and accurate are the problems that we can solve. It is the combination of mathematical ideas plus efficient programming that drives the progress in many disciplines. Future champions in the area thus will have to be qualified in their application domain, they will need a profound understanding of some mathematical ideas, and they need the skills to deliver fast code. The present textbook targets students which have programming skills already and do not shy away from mathematics, though they might be educated in computer science or an application domain. It introduces the basic concepts and ideas behind applied mathematics and parallel programming that we need to write numerical simulations for today’s multicore workstations. Our intention is not to dive into one particular application domain or to introduce a new programming language – we lay the generic foundations for future courses and projects in the area. The text is written in an accessible style which is easy to digest for students without years and years of mathematics education. It values clarity and intuition over formalism, and uses a simple N-body simulation setup to illustrate basic ideas that are of relevance in various different subdomains of scientific computing. Its primary goal is to make theoretical and paradigmatic ideas accessible to undergraduate students and to bring the fascination of the field across.Table of Contents1. The Pillars of Science.- 2.

Book SynopsisThis unique, accessible textbook presents a succession of implementations of the open-source RISC-V processor. Implementations are offered in increasing difficulty (non-pipelined, pipelined, deeply pipelined, multi-threaded, multicore).Each implementation is shown as a High-Level Synthesis (HLS) code in C++. This facilitates synthesis and testing on an FPGA-based development board (Such a board can be freely obtained from the Xilinx University Program targeting university professors).The book can be useful for several reasons. First, it is a novel way to introduce computer architecture: The codes given can serve as labs for a processor architecture course. Second, the book content is based on the RISC-V Instruction Set Architecture, which is an open-source machine language promising to become the main machine language to be taught, replacing DLX and MIPS. Third, all the designs are implemented through the HLS tool, which is able to translate a C program into an intellectual property (IP). Lastly, HLS will become the new standard for IP implementations, replacing Verilog/VHDL; already there are job positions tied to HLS, with the argument of rapid IP development.Hence, in addition to offering undergraduates a firm introduction, the textbook/guide can also serve engineers willing to implement processors on FPGA, as well as researchers willing to develop RISC-V based hardware simulators.Bernard Goossens is Professor in the Faculty of Sciences at the Université de Perpignan, France. He is author of the French-language book from Springer, Architecture et microarchitecture des processeurs, 2002.Table of ContentsPart I. Single core processors.- 1. Getting Ready.- 2.

Book Synopsis"I wrote this book because I love building robots. I want you to love building robots, too. It took me a while to learn about many of the tools and parts in amateur robotics. Perhaps by writing about my experiences, I can give you a head start."--David CookRobot Building for Beginners, Third Edition provides basic, practical knowledge on getting started in amateur robotics. There is a mix of content: from serious reference tables and descriptions to personal stories and humorous bits.The robot described and built in this book is battery powered and about the size of a lunch box. It is autonomous; that is, it isn''t remote controlled.The book is broken up into small chapters, suitable for bedtime (or bathroom) reading.The characteristics and purposes of each major component (resistor, transistor, wire, and motor) are described, followed by a hands-on experiment to demonstrate. Not only does this help the reader to understand a particular piece, but it also prepares them with processes to learn new parts on their own. An appendix offers an introduction to 3D printing and parts of the robot can, as an alternative, be "printed" using a 3D printer.The master project of the book is a simple, entertaining, line-following robot.Table of ContentsChapter 1.
