Understanding Open Source and Free Software Licensing

by Andrew M. St. Laurent

If you've held back from developing open source or free software projects because you don't understand the implications of the various licenses, you're not alone. Many developers believe in releasing their software freely, but have hesitated to do so because they're concerned about losing control over their software. Licensing issues are complicated, and both the facts and fallacies you hear word-of-mouth can add to the confusion. Understanding Open Source and Free Software Licensing helps you make sense of the different options available to you. This concise guide focuses on annotated licenses, offering an in-depth explanation of how they compare and interoperate, and how license choices affect project possibilities. Written in clear language that you don't have to be a lawyer to understand, the book answers such questions as: What rights am I giving up? How will my use of OS/FS licensing affect future users or future developers? Does a particular use of this software--such as combining it with proprietary software--leave me vulnerable to lawsuits? Following a quick look at copyright law, contracts, and the definition of "open source," the book tackles the spectrum of licensing, including:The MIT (or X), BSD, Apache and Academic Free licenses The GPL, LGPL, and Mozilla licenses The QT, Artistic, and Creative Commons licenses Classic Proprietary licenses Sun Community Source license and Microsoft Shared Source project The book wraps up with a look at the legal effects--both positive and negative--of open source/free software licensing. Licensing is a major part of what open source and free software are all about, but it's still one of the most complicated areas of law. Even the very simple licenses are tricky. Understanding Open Source and Free Software Licensing bridges the gap between the open source vision and the practical implications of its legal underpinnings. If open source and free software licenses interest you, this book will help you understand them. If you're an open source/free software developer, this book is an absolute necessity.

Understanding Problems of Practice: A Case Study In Design Research (Springerbriefs In Educational Communications And Technology Ser.)

by Dawn Hathaway Priscilla Norton

Today, K-12 practitioners are challenged to become educational innovators. Yet, little is available to the practitioner to guide their reflection about the design, development, and implementation of these innovations in their own practice. This brief approaches such problems of practice from the perspectives of design research. Although design research typically centers on the partnership between researchers and practitioners in real-world settings, relationships between researchers and practitioners are not always practical. In this brief, the authors explore how the design research process can make the goals, assumptions, processes, methods, and outcomes of design research uniquely accessible to the practitioner. In clear, explicit language, it introduces design research to practitioners using both expository discussions and a robust narrative case study approach that ably guides the reader through the phases of design research, namely:Theory to innovation to practiceUnderstanding problems of practiceCreating a design solutionAssessing the design solutionEvaluating learning outcomesCapturing lessons for practiceUnderstanding Problems of Practice is a singular resource for teachers and practitioners enrolled in graduate research courses or courses on teacher leadership. It also lends itself well as a supplement to professional development activities and studies at the district, school, and professional learning community levels.

Understanding Sponsored Search: Core Elements of Keyword Advertising

by Jim Jansen

This book addresses the underlying foundational elements, both theoretical and methodological, of sponsored search. As such, the contents are less affected by the ever-changing implementation aspects of technology. Rather than focusing on the how, this book examines what causes the how. Why do certain keywords work, while others do not? Why does that ad work well, when others that are similar do not? Why does a key phrase cost a given amount? Why do we measure what we do in keyword advertising? This book speaks to that curiosity to understand why we do what we do in sponsored search. The content flows through the major components of any sponsored search effort, regardless of the underlying technology or client or product. The book addresses keywords, ads, consumers, pricing, competitors, analytics, branding, marketing, and advertising, integrating these separate components into an incorporated whole. The focus is on the critical elements, with ample illustrations, and with enough detail to lead the interested reader to further inquiry.

Understanding the Digital World: What You Need to Know about Computers, the Internet, Privacy, and Security

by Brian W. Kernighan

Computers are everywhere. Some of them are highly visible, in laptops, tablets, cell phones, and smart watches. But most are invisible, like those in appliances, cars, medical equipment, transportation systems, power grids, and weapons. We never see the myriad computers that quietly collect, share, and sometimes leak vast amounts of personal data about us. Through computers, governments and companies increasingly monitor what we do. Social networks and advertisers know far more about us than we should be comfortable with, using information we freely give them. Criminals have all-too-easy access to our data. Do we truly understand the power of computers in our world?Understanding the Digital World explains how computer hardware, software, networks, and systems work. Topics include how computers are built and how they compute; what programming is and why it is difficult; how the Internet and the web operate; and how all of these affect our security, privacy, property, and other important social, political, and economic issues. This book also touches on fundamental ideas from computer science and some of the inherent limitations of computers. It includes numerous color illustrations, notes on sources for further exploration, and a glossary to explain technical terms and buzzwords.Understanding the Digital World is a must-read for all who want to know more about computers and communications. It explains, precisely and carefully, not only how they operate but also how they influence our daily lives, in terms anyone can understand, no matter what their experience and knowledge of technology.

Understanding the Linux Kernel

by Marco Cesati Daniel P. Bovet

In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn't kept waiting any longer than necessary for the relatively slow disks. The third edition of Understanding the Linux Kernel takes you on a guided tour of the most significant data structures, algorithms, and programming tricks used in the kernel. Probing beyond superficial features, the authors offer valuable insights to people who want to know how things really work inside their machine. Important Intel-specific features are discussed. Relevant segments of code are dissected line by line. But the book covers more than just the functioning of the code; it explains the theoretical underpinnings of why Linux does things the way it does. This edition of the book covers Version 2.6, which has seen significant changes to nearly every kernel subsystem, particularly in the areas of memory management and block devices. The book focuses on the following topics: Memory management, including file buffering, process swapping, and Direct memory Access (DMA) The Virtual Filesystem layer and the Second and Third Extended Filesystems Process creation and scheduling Signals, interrupts, and the essential interfaces to device drivers Timing Synchronization within the kernel Interprocess Communication (IPC) Program execution Understanding the Linux Kernel will acquaint you with all the inner workings of Linux, but it's more than just an academic exercise. You'll learn what conditions bring out Linux's best performance, and you'll see how it meets the challenge of providing good system response during process scheduling, file access, and memory management in a wide variety of environments. This book will help you make the most of your Linux system.

Understanding the Linux Kernel, 2nd Edition

by Daniel P. Bovet Marco Cesati

The new edition of Understanding the Linux Kernel takes you on a guided tour through the most significant data structures, many algorithms, and programming tricks used in the kernel. The book has been updated to cover version 2.4 of the kernel, which is quite different from version 2.2: the virtual memory system is entirely new, support for multiprocessor systems is improved, and whole new classes of hardware devices have been added. You'll learn what conditions bring out Linux's best performance, and how it meets the challenge of providing good system response during process scheduling, file access, and memory management in a wide variety of environments.
