Jack the Ripper and legacy codebases have more in common than you'd think. Inspired by forensic psychology methods, you'll learn strategies to predict the future of your codebase, assess refactoring direction, and understand how your team influences the design. With its unique blend of forensic psychology and code analysis, this book arms you with the strategies you need, no matter what programming language you use. Software is a living entity that's constantly changing. To understand software systems, we need to know where they came from and how they evolved. By mining commit data and analyzing the history of your code, you can start fixes ahead of time to eliminate broken designs, maintenance issues, and team productivity bottlenecks. In this book, you'll learn forensic psychology techniques to successfully maintain your software. You'll create a geographic profile from your commit data to find hotspots, and apply temporal coupling concepts to uncover hidden relationships between unrelated areas in your code. You'll also measure the effectiveness of your code improvements. You'll learn how to apply these techniques on projects both large and small. For small projects, you'll get new insights into your design and how well the code fits your ideas. For large projects, you'll identify the good and the fragile parts. Large-scale development is also a social activity, and the team's dynamics influence code quality. That's why this book shows you how to uncover social biases when analyzing the evolution of your system. You'll use commit messages as eyewitness accounts to what is really happening in your code. Finally, you'll put it all together by tracking organizational problems in the code and finding out how to fix them. Come join the hunt for better code! What You Need: You need Java 6 and Python 2.7 to run the accompanying analysis tools. You also need Git to follow along with the examples.

How much do we know about why we buy? What truly influences our decisions in today’s message-cluttered world? An eye-grabbing advertisement, a catchy slogan, an infectious jingle? Or do our buying decisions take place below the surface, so deep within our subconscious minds, we’re barely aware of them? In BUYOLOGY, Lindstrom presents the astonishing findings from his groundbreaking, three-year, seven-million-dollar neuromarketing study, a cutting-edge experiment that peered inside the brains of 2,000 volunteers from all around the world as they encountered various ads, logos, commercials, brands, and products. His startling results shatter much of what we have long believed about what seduces our interest and drives us to buy. Among the questions he explores: Does sex actually sell? To what extent do people in skimpy clothing and suggestive poses persuade us to buy products? Despite government bans, does subliminal advertising still surround us – from bars to highway billboards to supermarket shelves? Can “Cool” brands, like iPods, trigger our mating instincts? Can other senses – smell, touch, and sound - be so powerful as to physically arouse us when we see a product? Do companies copy from the world of religion and create rituals – like drinking a Corona with a lime – to capture our hard-earned dollars? Filled with entertaining inside stories about how we respond to such well-known brands as Marlboro, Nokia, Calvin Klein, Ford, and American Idol, BUYOLOGY is a fascinating and shocking journey into the mind of today’s consumer that will captivate anyone who’s been seduced – or turned off – by marketers’ relentless attempts to win our loyalty, our money, and our minds.
