    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.

    Rockefeller is held to be one of the wealthiest men who ever lived; he is also one of the most controversial figures in American history. Born of the unlikely union between a strict Baptist matriarch and her husband, a bigamist, alleged rapist, and snake-oil salesman, Rockefeller’s early childhood was spent learning how to shoulder an adult’s responsibility for his family and turn a deaf ear to the gossip that followed wherever his father went. This book contains highlights from the extraordinarily long life of a man many believed to be little better than a criminal, preying on small business owners to establish the supremacy of the Standard Oil Trust. John D. Rockefeller crushed his competitors and sparked massive public outrage against his businesses. Yet he also saved thousands of lives and helped establish respect for evidence-based medicine in the United States. From his teen years as a bookkeeper in a small commodities trading firm, to his imperial rule over the oil industry, to his early retirement and the decades he spent establishing philanthropic trusts in the fields of education and medicine, you will learn that there is no simple way to pass judgment on John D. Rockefeller’s life.

    On the other hand, if you're not well versed in the theory, you can fall into several traps. In SQL and Relational Theory, author C.J. Date demonstrates how you can apply relational theory directly to your use of SQL. With numerous examples and clear explanations of the reasoning behind them, you'll learn how to deal with common SQL dilemmas, such as:Should database access granted be through views instead of base tables? Nulls in your database are causing you to get wrong answers. Why? What can you do about it? Could you write an SQL query to find employees who have never been in the same department for more than six months at a time? SQL supports "quantified comparisons," but they're better avoided. Why? How do you avoid them? Constraints are crucially important, but most SQL products don't support them properly. What can you do to resolve this situation? Database theory and practice have evolved since Edgar Codd originally defined the relational model back in 1969. Independent of any SQL products, SQL and Relational Theory draws on decades of research to present the most up-to-date treatment of the material available anywhere. Anyone with a modest to advanced background in SQL will benefit from the many insights in this book.

    In Eloquent Ruby, Russ Olsen helps you write Ruby like true Rubyists do-so you can leverage its immense, surprising power. Olsen draws on years of experience internalizing the Ruby culture and teaching Ruby to other programmers. He guides you to the "Ah Ha!" moments when it suddenly becomes clear why Ruby works the way it does, and how you can take advantage of this language's elegance and expressiveness. Eloquent Ruby starts small, answering tactical questions focused on a single statement, method, test, or bug. You'll learn how to write code that actually looks like Ruby (not Java or C#); why Ruby has so many control structures; how to use strings, expressions, and symbols; and what dynamic typing is really good for. Next, the book addresses bigger questions related to building methods and classes. You'll discover why Ruby classes contain so many tiny methods, when to use operator overloading, and when to avoid it. Olsen explains how to write Ruby code that writes its own code-and why you'll want to. He concludes with powerful project-level features and techniques ranging from gems to Domain Specific Languages. A part of the renowned Addison-Wesley Professional Ruby Series, Eloquent Ruby will help you "put on your Ruby-colored glasses" and get results that make you a true believer.

    But when she loses her job, gets dumped and is made homeless within the space of a fortnight, Alex reluctantly returns to her home town – a place she thought she’d left for good 10 years earlier. With barely a penny to her name… Alex is surprised to find there are some advantages to moving back: reconnecting with old friends who had been such a big part of her teenage years. Although being back brings up old feelings Alex thought she had buried for good, feelings that should be well and truly left in the past – especially when it came to her old high school boyfriend, Lewis Ashworth. Desperate to return to her London lifestyle, Alex takes advice from her old school friend Cody McKenzie, who suggests she only has to “fake it till she makes it” How hard can that be? After all, hadn’t she been doing that for years? Whether reluctantly trying to drive her nan’s mobility scooter, putting bullying bosses in their place or looking for creative ways to avoid her mum’s increasingly weird cooking, follow Alex’s laugh-out-loud journey to “making it”

    The authors, who developed the metaobject protocol andwho were among the group that developed CLOS, introduce this new approach toprogramming language design, describe its evolution and design principles, andpresent a formal specification of a metaobject protocol for CLOS.Kiczales, desRivi?res, and Bobrow show that the "art of metaobject protocol design" lies increating a synthetic combination of object-oriented and reflective techniques thatcan be applied under existing software engineering considerations to yield a newapproach to programming language design that meets a broad set of designcriteria.One of the major benefits of including the metaobject protocol inprogramming languages is that it allows users to adjust the language to better suittheir needs. Metaobject protocols also disprove the adage that adding moreflexibility to a programming language reduces its performance. In presenting theprinciples of metaobject protocols, the authors work with actual code for asimplified implementation of CLOS and its metaobject protocol, providing anopportunity for the reader to gain hands-on experience with the design process. Theyalso include a number of exercises that address important concerns and openissues.Gregor Kiczales and Jim des Rivi?res, are Members of the Research Staff, andDaniel Bobrow is a Research Fellow, in the System Sciences Laboratory at Xerox PaloAlto Research Center.
