Limited to a strict interpretation of its definition, open source consists of a set of rules which apply to a piece of software and which specify how the software and derivatives of it may be used. However, it is widely seen as much more than a simple licensing agreement, it is a ´´philoshophy´´, a ´´production model´´, a ´´way of organizing projects´´, or even ´´a new innovation model´´. But how are open source projects organized and how is work coordinated and distributed between its developers? This work contributes by examining actual source code changes, comparing 29 projects. Which developers collaborate in the same files and wich work exclusively in their own domain? Looking for patterns across projects, this work attempts to identify coordination styles in open source projects.
A hands-on introduction to computer science concepts for non-technical readers. Activities include word searches, mazes, ´´Find the Bug!´´ hunts, matching games, ´´Color by Boolean´´ (a twist on the classic Paint by Numbers), and more. The Computer Science Activity Book is the perfect companion for curious youngsters and grown-ups -- especially those who think they´ll never understand how computers work. As readers work their way through this collection of fun and innovative hands-on exercises, they´ll learn the core programming concepts and computer terminology that form the foundation of a STEM education. Readers learn about historical figures like Charles Babbage, Ada Lovelace, Grace Hopper, and Alan Turing; how computers store data and run programs; and how the parts of a computer work together (like the hard drive, RAM, and CPU) through activities that teach foundational programming concepts like drawing a garden of flowers using for loops and creating creatures with conditional statements.
Continuing his exploration of the organization of complexity and the science of design, this new edition of Herbert Simon´s classic work on artificial intelligence adds a chapter that sorts out the current themes and tools--chaos, adaptive systems, genetic algorithms--for analyzing complexity and complex systems.
This work is carried out at Airbus Defence and Space-Ulm, intend to analyze the feasibility of low cost radar processor for unmanned armed vehicles. Various scheduling schemes were proposed and their results are compared. It is concluded that low cost ARM Cortex processor can be used for this purpose which also leaves some buffer for future adaption. This thesis will will give a good glimpse of how multi-core processor features can be effectively used.
Explorations in Art and Technology presents the explorations in Art and Technology of the Creativity& Cognition Research Studios. The Studios were created to bring together the visions and expertise of people working at the boundaries of art and digital media. The book explores the nature of intersection and correspondence across these disciplinary boundaries, practices and conceptual frameworks through artists´ illustrated contributions and studies of work in progress. These experiences are placed within the context of recent digital art history and the innovations of early pioneers.
Launch into coding with Mission: Python, a space-themed guide to building a complete computer game in Python. As you work through the book, you´ll build exercises and mini-projects, like making a spacewalk simulator and creating an astronaut´s safety checklist that will put your new Python skills to the test. Before you know it, you´ll have a working, awesome game to stump your friends with (and some nifty coding skills, too!). You can follow this book using a Raspberry Pi or a Microsoft Windows PC, and the 3D graphics and sound effects you need are provided as a download.
Work with blockchain and understand its potential application beyond cryptocurrencies in the domains of healthcare, Internet of Things, finance, decentralized organizations, and open science. Featuring case studies and practical insights generated from a start-up spun off from the author´s own lab, this book covers a unique mix of topics not found in others and offers insight into how to overcome real hurdles that arise as the market and consumers grow accustomed to blockchain based start-ups. You´ll start with a review of the historical origins of blockchain and explore the basic cryptography needed to make the blockchain work for Bitcoin. You will then learn about the technical advancements made in the surrounded ecosystem: the Ethereum virtual machine, Solidity, Colored Coins, the Hyperledger Project, Blockchain-as-a-service offered through IBM, Microsoft and more. This book looks at the consequences of machine-to-machine transactions using the blockchain socially, technologically, economically and politically. Blockchain Enabled Applications provides you with a clear perspective of the ecosystem that has developed around the blockchain and the various industries it has penetrated. What You´ll Learn Implement the code-base from Fabric and Sawtooth, two open source blockchain-efforts being developed under the Hyperledger Project Evaluate the benefits of integrating blockchain with emerging technologies, such as machine learning and artificial intelligence in the cloud Use the practical insights provided by the case studies to your own projects or start-up ideas Set up a development environment to compile and manage projects Who This Book Is For Developers who are interested in learning about the blockchain as a data-structure, the recent advancements being made and how to implement the code-base. Decision makers within large corporations (product managers, directors or CIO level executives) interested in implementing the blockchain who need more practical insights and not just theory.
Learn Spring Boot and how to build Java-based enterprise, web, and microservice applications with it. In this book, you´ll see how to work with relational and NoSQL databases, build your first microservice, enterprise, or web application, and enhance that application with REST APIs. You´ll also learn how to build reactive web applications using Spring Boot along with Spring Web Reactive. Then you´ll secure your Spring Boot-created application or service before testing and deploying it. After reading and learning with Beginning Spring Boot 2 , you´ll have the skills and techniques to start building your first Spring Boot applications and microservices with confidence to take the next steps in your career journey. What You´ll Learn Use Spring Boot autoconfiguration Work with relational and NoSQL databases Build web applications with Spring Boot Apply REST APIs using Spring Boot Create reactive web applications using Spring Web Reactive Secure your Spring Boot applications or web services Test and deploy your Spring Boot applications Who This Book Is For Experienced Java and Spring Framework developers who are new to the new Spring Boot micro-framework.
This book presents the first comprehensive overview of various verifiable computing techniques, which allow the computation of a function on outsourced data to be delegated to a server. It provides a brief description of all the approaches and highlights the properties each solution achieves. Further, it analyzes the level of security provided, how efficient the verification process is, who can act as a verifier and check the correctness of the result, which function class the verifiable computing scheme supports, and whether privacy with respect to t he input and/or output data is provided. On the basis of this analysis the authors then compare the different approaches and outline possible directions for future work. The book is of interest to anyone wanting to understand the state of the art of this research field.
