How Open Source Ate Software: Understand The Open Source Movement And So Much More
by Gordon HaffLearn how free software became open source and how you can sell open source software. This book provides a historical context of how open source has thoroughly transformed how we write software, how we cooperate, how we communicate, how we organize, and, ultimately, how we think about business values.You’ll look at project and community examples including Linux, BSD, Apache, and Kubernetes, understand the open source development model, and how open source has influenced approaches more broadly, even proprietary software, such as open betas. You'll also examine the flipside, the "Second Machine Age," and the challenges of open source-based business models.Today, open source serves as shorthand for much broader trends and behaviors. It’s not just about a free (in all senses of the word) alternative to commercial software. It increasingly is the new commercial software. How Open Source Ate Software reveals how open source has much in common, and is often closely allied, with many other trends in business and society. You'll see how it enables projects that go beyond any individual company. That makes open source not just a story about software, but a story about almost everything.What You'll LearnUnderstand open source opportunities and challengesSell software if you’re giving it awayApply open source principles more broadly to openorg, devops, etc.Review which organizational incentives you can implement Who This Book Is ForAnyone who has an interest in what is happening in open source and the open source community, and anyone who is contemplating making a business that involves open source.
How Smart Machines Think (The\mit Press Ser.)
by Sean GerrishEverything you've always wanted to know about self-driving cars, Netflix recommendations, IBM's Watson, and video game-playing computer programs.The future is here: Self-driving cars are on the streets, an algorithm gives you movie and TV recommendations, IBM's Watson triumphed on Jeopardy over puny human brains, computer programs can be trained to play Atari games. But how do all these things work? In this book, Sean Gerrish offers an engaging and accessible overview of the breakthroughs in artificial intelligence and machine learning that have made today's machines so smart.Gerrish outlines some of the key ideas that enable intelligent machines to perceive and interact with the world. He describes the software architecture that allows self-driving cars to stay on the road and to navigate crowded urban environments; the million-dollar Netflix competition for a better recommendation engine (which had an unexpected ending); and how programmers trained computers to perform certain behaviors by offering them treats, as if they were training a dog. He explains how artificial neural networks enable computers to perceive the world—and to play Atari video games better than humans. He explains Watson's famous victory on Jeopardy, and he looks at how computers play games, describing AlphaGo and Deep Blue, which beat reigning world champions at the strategy games of Go and chess. Computers have not yet mastered everything, however; Gerrish outlines the difficulties in creating intelligent agents that can successfully play video games like StarCraft that have evaded solution—at least for now. Gerrish weaves the stories behind these breakthroughs into the narrative, introducing readers to many of the researchers involved, and keeping technical details to a minimum. Science and technology buffs will find this book an essential guide to a future in which machines can outsmart people.

How to Design Programs, second edition: An Introduction to Programming and Computing (The\mit Press Ser.)
by Matthias Felleisen Robert Bruce Findler Matthew Flatt Shriram KrishnamurthiA completely revised edition, offering new design recipes for interactive programs and support for images as plain values, testing, event-driven programming, and even distributed programming.This introduction to programming places computer science at the core of a liberal arts education. Unlike other introductory books, it focuses on the program design process, presenting program design guidelines that show the reader how to analyze a problem statement, how to formulate concise goals, how to make up examples, how to develop an outline of the solution, how to finish the program, and how to test it. Because learning to design programs is about the study of principles and the acquisition of transferable skills, the text does not use an off-the-shelf industrial language but presents a tailor-made teaching language. For the same reason, it offers DrRacket, a programming environment for novices that supports playful, feedback-oriented learning. The environment grows with readers as they master the material in the book until it supports a full-fledged language for the whole spectrum of programming tasks.This second edition has been completely revised. While the book continues to teach a systematic approach to program design, the second edition introduces different design recipes for interactive programs with graphical interfaces and batch programs. It also enriches its design recipes for functions with numerous new hints. Finally, the teaching languages and their IDE now come with support for images as plain values, testing, event-driven programming, and even distributed programming.

How to Turn Down a Billion Dollars: The Snapchat Story
by Billy Gallagher"In the grand tradition of Ben Mezrich's The Accidental Billionaires (2009)... an engaging look into a fascinating subculture of millions." —Booklist"Breezy...How to Turn Down a Billion Dollars ably if uncritically chronicles the short history of a young company catering to young users, with a young chief executive, and reveals, intentionally or not, the limitations that come with that combination." —Wall Street JournalThe improbable and exhilarating story of the rise of Snapchat from a frat boy fantasy to a multi-billion dollar internet unicorn that has dramatically changed the way we communicate.In 2013 Evan Spiegel, the brash CEO of the social network Snapchat, and his co-founder Bobby Murphy stunned the press when they walked away from a three-billion-dollar offer from Facebook: how could an app teenagers use to text dirty photos dream of a higher valuation? Was this hubris, or genius? In How to Turn Down a Billion Dollars, tech journalist Billy Gallagher takes us inside the rise of one of Silicon Valley's hottest start-ups. Snapchat developed from a simple wish for disappearing pictures as Stanford junior Reggie Brown nursed regrets about photos he had sent. After an epic feud between best friends, Brown lost his stake in the company, while Spiegel has gone on to make a name for himself as a visionary—if ruthless—CEO worth billions, linked to celebrities like Taylor Swift and his wife, Miranda Kerr. A fellow Stanford undergrad and fraternity brother of the company’s founding trio, Gallagher has covered Snapchat from the start. He brings unique access to a company Bloomberg Business called “a cipher in the Silicon Valley technology community.” Gallagher offers insight into challenges Snapchat faces as it transitions from a playful app to one of the tech industry’s preeminent public companies. In the tradition of great business narratives, How to Turn Down a Billion Dollars offers the definitive account of a company whose goal is no less than to remake the future of entertainment.

The Huawei and Snowden Questions
by Olav LysneThis open access book answers two central questions: firstly, is it at all possible to verify electronic equipment procured from untrusted vendors? Secondly, can I build trust into my products in such a way that I support verification by untrusting customers? In separate chapters the book takes readers through the state of the art in fields of computer science that can shed light on these questions. In a concluding chapter it discusses realistic ways forward. In discussions on cyber security, there is a tacit assumption that the manufacturer of equipment will collaborate with the user of the equipment to stop third-party wrongdoers. The Snowden files and recent deliberations on the use of Chinese equipment in the critical infrastructures of western countries have changed this. The discourse in both cases revolves around what malevolent manufacturers can do to harm their own customers, and the importance of the matter is on par with questions of national security.This book is of great interest to ICT and security professionals who need a clear understanding of the two questions posed in the subtitle, and to decision-makers in industry, national bodies and nation states.
Human and Machine Learning: Visible, Explainable, Trustworthy and Transparent (Human–Computer Interaction Series)
by Jianlong Zhou Fang ChenWith an evolutionary advancement of Machine Learning (ML) algorithms, a rapid increase of data volumes and a significant improvement of computation powers, machine learning becomes hot in different applications. However, because of the nature of “black-box” in ML methods, ML still needs to be interpreted to link human and machine learning for transparency and user acceptance of delivered solutions. This edited book addresses such links from the perspectives of visualisation, explanation, trustworthiness and transparency. The book establishes the link between human and machine learning by exploring transparency in machine learning, visual explanation of ML processes, algorithmic explanation of ML models, human cognitive responses in ML-based decision making, human evaluation of machine learning and domain knowledge in transparent ML applications. This is the first book of its kind to systematically understand the current active research activities and outcomes related to human and machine learning. The book will not only inspire researchers to passionately develop new algorithms incorporating human for human-centred ML algorithms, resulting in the overall advancement of ML, but also help ML practitioners proactively use ML outputs for informative and trustworthy decision making. This book is intended for researchers and practitioners involved with machine learning and its applications. The book will especially benefit researchers in areas like artificial intelligence, decision support systems and human-computer interaction.
