Newly retired from the FBI and alone after the tragic death of his wife, Cliff Knowles takes up geocaching. While looking for a cache in the mountains he comes across a human skeleton and reports it to the sheriff's office. Then a second body is found - a fresh corpse this time - right after Cliff found another geocache nearby. When it turns out the first remains are those of a fugitive he was supposed to arrest years earlier, he becomes a suspect in a multiple homicide investigation. He has no choice but to use his sleuthing skills to identify the mysterious cache owner, known only as Enigmal, and free himself from suspicion.
“This is the most culturally sophisticated history of the Internet yet written. We can’t make sense of what the Internet means in our lives without reading Schulte’s elegant account of what the Internet has meant at various points in the past 30 years.”—Siva Vaidhyanathan, Chair of the Department of Media Studies at The University of Virginia In the 1980s and 1990s, the internet became a major player in the global economy and a revolutionary component of everyday life for much of the United States and the world. It offered users new ways to relate to one another, to share their lives, and to spend their time—shopping, working, learning, and even taking political or social action. Policymakers and news media attempted—and often struggled—to make sense of the emergence and expansion of this new technology. They imagined the internet in conflicting terms: as a toy for teenagers, a national security threat, a new democratic frontier, an information superhighway, a virtual reality, and a framework for promoting globalization and revolution. Schulte maintains that contested concepts had material consequences and helped shape not just our sense of the internet, but the development of the technology itself. Cached focuses on how people imagine and relate to technology, delving into the political and cultural debates that produced the internet as a core technology able to revise economics, politics, and culture, as well as to alter lived experience. Schulte illustrates the conflicting and indirect ways in which culture and policy combined to produce this transformative technology.

Learning to build distributed systems is hard, especially if they are large scale. It's not that there is a lack of information out there. You can find academic papers, engineering blogs, and even books on the subject. The problem is that the available information is spread out all over the place, and if you were to put it on a spectrum from theory to practice, you would find a lot of material at the two ends, but not much in the middle. That is why I decided to write a book to teach the fundamentals of distributed systems so that you don’t have to spend countless hours scratching your head to understand how everything fits together. This is the guide I wished existed when I first started out, and it's based on my experience building large distributed systems that scale to millions of requests per second and billions of devices. If you develop the back-end of web or mobile applications (or would like to!), this book is for you. When building distributed systems, you need to be familiar with the network stack, data consistency models, scalability and reliability patterns, and much more. Although you can build applications without knowing any of that, you will end up spending hours debugging and re-designing their architecture, learning lessons that you could have acquired in a much faster and less painful way.
He was in a tight spot. He knew he couldn’t stand off the Law and Breen, too. The Law was after him for the murder of a marshal—a murder he didn’t commit. Breen was after him for revenge—and Breen wouldn’t stop at anything … blackmail, a frame-up … or murder. He was desperate now and vowed to find a way out—or make one.
On the World Wide Web, speed and efficiency are vital. Users have little patience for slow web pages, while network administrators want to make the most of their available bandwidth. A properly designed web cache reduces network traffic and improves access times to popular web sites--a boon to network administrators and web users alike.Web Caching hands you all the technical information you need to design, deploy, and operate an effective web caching service. It starts with the basics of how web caching works, from the HTTP headers that govern cachability to cache validation and replacement algorithms.Topics covered in this book include: Designing an effective cache solution Configuring web browsers to use a cache Setting up a collection of caches that can talk to each other Configuring an interception cache or proxy Monitoring and fine-tuning the performance of a cache Configuring web servers to cooperate with web caches Benchmarking cache products The book also covers the important political aspects of web caching, including privacy, intellectual property, and security issues.Internet service providers, large corporations, or educational institutions--in short, any network that provides connectivity to a wide variety of users--can reap enormous benefit from running a well-tuned web caching service. Web Caching shows you how to do it right.
The Semantic Web is a Web defined and linked in a way that it can be used by machines not just for display purposes, but also for automation, integration and reuse of data across various applications. This work presents technologies that will enable the Semantic Web to become a reality.
