Now delete that picture. In Once Upon an Algorithm, Martin Erwig explains computation as something that takes place beyond electronic computers, and computer science as the study of systematic problem solving. Erwig points out that many daily activities involve problem solving. Getting up in the morning, for example: You get up, take a shower, get dressed, eat breakfast. This simple daily routine solves a recurring problem through a series of well-defined steps. In computer science, such a routine is called an algorithm.Erwig illustrates a series of concepts in computing with examples from daily life and familiar stories. Hansel and Gretel, for example, execute an algorithm to get home from the forest. The movie Groundhog Day illustrates the problem of unsolvability; Sherlock Holmes manipulates data structures when solving a crime; the magic in Harry Potter's world is understood through types and abstraction; and Indiana Jones demonstrates the complexity of searching. Along the way, Erwig also discusses representations and different ways to organize data; "intractable" problems; language, syntax, and ambiguity; control structures, loops, and the halting problem; different forms of recursion; and rules for finding errors in algorithms.This engaging book explains computation accessibly and shows its relevance to daily life. Something to think about next time we execute the algorithm of getting up in the morning.

    According to the August Forrester Report, 56 percent of IT managers interviewed at Global 2,500 companies are already using some type of open source software in their infrastructure and another 6 percent will install it in the next two years. This revolutionary model for collaborative software development is being embraced and studied by many of the biggest players in the high-tech industry, from Sun Microsystems to IBM to Intel.The Cathedral & the Bazaar is a must for anyone who cares about the future of the computer industry or the dynamics of the information economy. Already, billions of dollars have been made and lost based on the ideas in this book. Its conclusions will be studied, debated, and implemented for years to come. According to Bob Young, "This is Eric Raymond's great contribution to the success of the open source revolution, to the adoption of Linux-based operating systems, and to the success of open source users and the companies that supply them."The interest in open source software development has grown enormously in the past year. This revised and expanded paperback edition includes new material on open source developments in 1999 and 2000. Raymond's clear and effective writing style accurately describing the benefits of open source software has been key to its success. With major vendors creating acceptance for open source within companies, independent vendors will become the open source story in 2001.

    This long-awaited revision contains changes throughout the text. There are new implementations of most of the major programming systems in the book, including the interpreters and compilers, and the authors have incorporated many small changes that reflect their experience teaching the course at MIT since the first edition was published. A new theme has been introduced that emphasizes the central role played by different approaches to dealing with time in computational models: objects with state, concurrent programming, functional programming and lazy evaluation, and nondeterministic programming. There are new example sections on higher-order procedures in graphics and on applications of stream processing in numerical programming, and many new exercises. In addition, all the programs have been reworked to run in any Scheme implementation that adheres to the IEEE standard.

    The world will never be slower than it is right now, says Beth Comstock, the former Vice Chair and head of marketing and innovation at GE. But confronting relentless change is hard. Companies get disrupted as challengers steal away customers; employees have to move ahead without knowing the answers. To thrive in today’s world, every one of us has to make change part of our job. In Imagine It Forward, Comstock, in a candid and deeply personal narrative, shares lessons from a thirty year career as the change-maker in chief, navigating the space between the established and the unproven. As the woman who initiated GE's digital and clean-energy transformations, and its FastWorks methodology, she challenged a global organization to not wait for perfection but to spot trends, take smart risks and test new ideas more often. She shows how each one of us can—in fact, must -- become a “change maker.” “Ideas are rarely the problem,” writes Comstock. “What holds all of us back, really—is fear. It’s the attachment to the old, to ‘What We Know.’” Change is messy and fraught with tension, uncertainty and failure. Being “change ready” calls for the courage to defy convention, the resilience to overcome doubts, and the savvy to know when to go around corporate gatekeepers to reinvent what is possible. Among the practical takeaways Comstock offers: • The power of discovery—bringing the outside into your organization. It’is about turning the world into a classroom. • Find a spark—provocateurs who challenge established ways of thinking can be a powerful catalyst for change. • Give yourself permission—every change maker must learn to give herself permission to push outside expectations and boundaries. Confronting today’s accelerating change requires an extraordinary degree of problem-solving, collaboration, and forward-thinking leadership to unlock every person’s potential. Imagine It Forward masterfully points the way.

    It’s not just computer hackers and cyber crooks who lurk in the dark corners of the Web—the cops are there, too.In The Internet Police, Ars Technica deputy editor Nate Anderson takes readers on a behind-the-screens tour of landmark cybercrime cases, revealing how criminals continue to find digital and legal loopholes even as police hurry to cinch them closed. From the Cleveland man whose "natural male enhancement" pill inadvertently protected the privacy of your e-mail to the Russian spam king who ended up in a Milwaukee jail to the Australian arrest that ultimately led to the breakup of the largest child pornography ring in the United States, Anderson draws on interviews, court documents, and law-enforcement reports to reconstruct accounts of how online policing actually works. Questions of online crime are as complex and interconnected as the Internet itself. With each episode in The Internet Police, Anderson shows the dark side of online spaces—but also how dystopian a fully "ordered" alternative would be.Includes an afterword that details law enforcement's dramatic seizure of the online black market Silk Road.
