How do the experts solve difficult problems in software development? In this unique and insightful book, leading computer scientists offer case studies that reveal how they found unusual, carefully designed solutions to high-profile projects. You will be able to look over the shoulder of major coding and design experts to see problems through their eyes. This is not simply another design patterns book, or another software engineering treatise on the right and wrong way to do things. The authors think aloud as they work through their project's architecture, the tradeoffs made in its construction, and when it was important to break rules. This book contains 33 chapters contributed by Brian Kernighan, Karl Fogel, Jon Bentley, Tim Bray, Elliotte Rusty Harold, Michael Feathers, Alberto Savoia, Charles Petzold, Douglas Crockford, Henry S. Warren, Jr., Ashish Gulhati, Lincoln Stein, Jim Kent, Jack Dongarra and Piotr Luszczek, Adam Kolawa, Greg Kroah-Hartman, Diomidis Spinellis, Andrew Kuchling, Travis E. Oliphant, Ronald Mak, Rogerio Atem de Carvalho and Rafael Monnerat, Bryan Cantrill, Jeff Dean and Sanjay Ghemawat, Simon Peyton Jones, Kent Dybvig, William Otte and Douglas C. Schmidt, Andrew Patzer, Andreas Zeller, Yukihiro Matsumoto, Arun Mehta, TV Raman, Laura Wingerd and Christopher Seiwald, and Brian Hayes. Beautiful Code is an opportunity for master coders to tell their story. All author royalties will be donated to Amnesty International.
Although most people don't give security much attention until their personal or business systems are attacked, this thought-provoking anthology demonstrates that digital security is not only worth thinking about, it's also a fascinating topic. Criminals succeed by exercising enormous creativity, and those defending against them must do the same. Beautiful Security explores this challenging subject with insightful essays and analysis on topics that include: The underground economy for personal information: how it works, the relationships among criminals, and some of the new ways they pounce on their prey How social networking, cloud computing, and other popular trends help or hurt our online security How metrics, requirements gathering, design, and law can take security to a higher level The real, little-publicized history of PGP This book includes contributions from: Peiter "Mudge" Zatko Jim Stickley Elizabeth Nichols Chenxi Wang Ed Bellis Ben Edelman Phil Zimmermann and Jon Callas Kathy Wang Mark Curphey John McManus James Routh Randy V. Sabett Anton Chuvakin Grant Geyer and Brian Dunphy Peter Wayner Michael Wood and Fernando Francisco All royalties will be donated to the Internet Engineering Task Force (IETF).
New information technologies (IT) hold the promise of better health in a world increasingly coping with chronic illness. The miniaturization of ever-more powerful sensing devices, along with the collection, analysis, and sharing of data, support activities in homes and clinics that let patients have a greater role in their own health care. This article takes you on a tour of specific technologies, tools, and trends to help you understand what's been accomplished, what's feasible in the near future, and why some technologies seem to languish despite their apparent advantages. You'll also discover how these groundbreaking approaches can help lower the enormous health care costs in the US. Learn how devices and sensors are transforming medical equipment and helping self-monitoring go mainstream Understand how data is gathered, stored, and analyzed, as well as the role shared data plays in clinical research Explore the way IT helps medical teams coordinate, and how "telehealth" enables better patient treatment at home Learn how health IT helps empower patients by providing more transparency in the system Examine the standards in data storage and electronic health records, and weaknesses that need to be addressed in current systems
Many claims are made about how certain tools, technologies, and practices improve software development. But which claims are verifiable, and which are merely wishful thinking? In this book, leading thinkers such as Steve McConnell, Barry Boehm, and Barbara Kitchenham offer essays that uncover the truth and unmask myths commonly held among the software development community. Their insights may surprise you. Are some programmers really ten times more productive than others? Does writing tests first help you develop better code faster? Can code metrics predict the number of bugs in a piece of software? Do design patterns actually make better software? What effect does personality have on pair programming? What matters more: how far apart people are geographically, or how far apart they are in the org chart? Contributors include: Jorge Aranda Tom Ball Victor R.

The term "peer-to-peer" has come to be applied to networks that expect end users to contribute their own files, computing time, or other resources to some shared project. Even more interesting than the systems' technical underpinnings are their socially disruptive potential: in various ways they return content, choice, and control to ordinary users.While this book is mostly about the technical promise of peer-to-peer, we also talk about its exciting social promise. Communities have been forming on the Internet for a long time, but they have been limited by the flat interactive qualities of email and Network newsgroups. People can exchange recommendations and ideas over these media, but have great difficulty commenting on each other's postings, structuring information, performing searches, or creating summaries. If tools provided ways to organize information intelligently, and if each person could serve up his or her own data and retrieve others' data, the possibilities for collaboration would take off. Peer-to-peer technologies along with metadata could enhance almost any group of people who share an interest--technical, cultural, political, medical, you name it.This book presents the goals that drive the developers of the best-known peer-to-peer systems, the problems they've faced, and the technical solutions they've found.
