During the summer of his senior year at college, while earning a B.A. in Economics and Political Science, David P. Spears spent eighty hours undercover as a panhandler. Systematically recording every transaction at the exit ramp, Spears captured a rarely seen picture of how modern urban charity works.This book is the record of his adventures, part economic research, part investigative journalism. Both the numbers and the stories behind the numbers provide answers to the questions we’ve all been wondering: Who gives more to panhandlers—men or women? What percentage of drivers roll down their windows to donate? And most important of all, how much can a panhandler earn per hour?Get out your bi-weekly pay stub—by the end of this book you’ll know if you make more or less than the guy with the cardboard sign.

    Fat, they told us, was the enemy. Then it was salt, then sugar, then cholesterol... and on it goes. Americans listened and they lost -- but not their excess fat. What they lost was their health and waistlines. Americans are the fattest people on earth... and why? Mainly because of the food they eat. In this scientific and revolutionary book, based on Nobel Prize-winning research, medical visionary and former Massachusetts Institute of Technology researcher Dr. Barry Sears makes peak physical and mental performance, as well as permanent fat loss, simple for you to understand and achieve. With lists of good and bad carbohydrates, easy-to-follow food blocks and delicious recipes, The Zone provides all you need to begin your journey toward permanent fat loss, great health and all-round peak performance. In balance, your body will not only burn fat, but you'll fight heart disease, diabetes, PMS, chronic fatigue, depression and cancer, as well as alleviate the painful symptoms of diseases such as multiple sclerosis and HIV. This Zone state of exceptional health is well-known to champion athletes. Your own journey toward it can begin with your next meal. You will no longer think of food as merely an item of pleasure or a means to appease hunger. Food is your medicine and your ticket to that state of ultimate body balance, strength and great health: the Zone.

    The vision behind Clojure is of a radically simple language framework holding together a sophisticated collection of programming features. Learning Clojure involves much more than just learning the mechanics of the language. To really get Clojure you need to understand the ideas underlying this structure of framework and features. You need this book: an accessible introduction to Clojure that focuses on the ideas behind the language as well as the practical details of writing code.

    Focus is on an in-depth analysis and exposition of not-so-obvious coding errors in the sample code provided. The theme is to answer the questions 'How couild I have automatically detected this bug' and 'How could I have prevented this bug'? Chapters include programmer attitudes, techniques and debugging methodology. A particularly revealing chapter is "Treacheries of the Trade", should be required reading for all C maniacs. The author has been a professional programmer for seventeen years and draws heavily (and candidly) on actual coding problems and practices based on years of experience at Microsoft.

    At that career level, you’ll no longer be required to work towards the next promotion, and being promoted beyond it is exceptional rather than expected. At that point your career path will branch, and you have to decide between remaining at your current level, continuing down the path of technical excellence to become a Staff Engineer, or switching into engineering management. Of course, the specific titles vary by company, and you can replace “Senior Engineer” and “Staff Engineer” with whatever titles your company prefers. Over the past few years we’ve seen a flurry of books unlocking the engineering management career path, like Camille Fournier’s The Manager’s Path, Julie Zhuo’s The Making of a Manager, Lara Hogan’s Resilient Management and my own, An Elegant Puzzle. The management career isn’t an easy one, but increasingly there are maps available for navigating it. On the other hand, the transition into Staff Engineer, and its further evolutions like Principal and Distinguished Engineer, remains challenging and undocumented. What are the skills you need to develop to reach Staff Engineer? Are technical abilities alone sufficient to reach and succeed in that role? How do most folks reach this role? What is your manager’s role in helping you along the way? Will you enjoy being a Staff Engineer or you will toil for years to achieve a role that doesn’t suit you? "Staff Engineer: Leadership beyond the management track" is a pragmatic look at attaining and operating in these Staff-plus roles.

    Before we delve into the intricacies of JavaScript, we need to know why it is used. While HTML tells your browser how your webpage will look, JavaScript is used for dynamic content and to add functionality. Using this book, you will understand the concept of JavaScript and its use in web designing. You will also have a look at jQuery in general. You will learn about Functions, Operators, the concept of Variables, Conditions and Loops, Arrays, and the basics of jQuery in this book. Instead of wandering through loads of theory, we have used practical examples in this book. The examples in this book are compatible with almost every browser. Instead of using the verbatim code, you can modify the code and see the change in the output thereby understanding the subtle nuances of JavaScript. By the end of the book, with practice, you can achieve better things and get more acquainted with JavaScript.

     -Byte, September 1995 I can't begin to tell you how many pleasurable hours of study and recreation they have afforded me! I have pored over them in cars, restaurants, at work, at home... and even at a Little League game when my son wasn't in the line-up. -Charles Long If you think you're a really good programmer... read [Knuth's] Art of Computer Programming... You should definitely send me a resume if you can read the whole thing. -Bill Gates It's always a pleasure when a problem is hard enough that you have to get the Knuths off the shelf. I find that merely opening one has a very useful terrorizing effect on computers. -Jonathan Laventhol This first volume in the series begins with basic programming concepts and techniques, then focuses more particularly on information structures-the representation of information inside a computer, the structural relationships between data elements and how to deal with them efficiently. Elementary applications are given to simulation, numerical methods, symbolic computing, software and system design. Dozens of simple and important algorithms and techniques have been added to those of the previous edition. The section on mathematical preliminaries has been extensively revised to match present trends in research. Ebook (PDF version) produced by Mathematical Sciences Publishers (MSP), http: //msp.org

    It runs on PCs rather than servers and is ideal for small- to mid-sized businesses and households. But Access is still intimidating to learn. It doesn't help that each new version crammed in yet another set of features; so many, in fact, that even the pros don't know where to find them all. Access 2007 breaks this pattern with some of the most dramatic changes users have seen since Office 95. Most obvious is the thoroughly redesigned user interface, with its tabbed toolbar (or "Ribbon") that makes features easy to locate and use. The features list also includes several long-awaited changes. One thing that hasn't improved is Microsoft's documentation. To learn the ins and outs of all the features in Access 2007, Microsoft merely offers online help.Access 2007: The Missing Manual was written from the ground up for this redesigned application. You will learn how to design complete databases, maintain them, search for valuable nuggets of information, and build attractive forms for quick-and-easy data entry. You'll even delve into the black art of Access programming (including macros and Visual Basic), and pick up valuable tricks and techniques to automate common tasks -- even if you've never touched a line of code before. You will also learn all about the new prebuilt databases you can customize to fit your needs, and how the new complex data feature will simplify your life. With plenty of downloadable examples, this objective and witty book will turn an Access neophyte into a true master.

    You’ll learn to spot which tests are performing, which need refactoring, and which need to be deleted entirely! Upgrade your testing suite with new testing styles, good patterns, and reliable automated testing.
