This authoritative book scrapes away these bad features to reveal a subset of JavaScript that's more reliable, readable, and maintainable than the language as a whole--a subset you can use to create truly extensible and efficient code.Considered the JavaScript expert by many people in the development community, author Douglas Crockford identifies the abundance of good ideas that make JavaScript an outstanding object-oriented programming language-ideas such as functions, loose typing, dynamic objects, and an expressive object literal notation. Unfortunately, these good ideas are mixed in with bad and downright awful ideas, like a programming model based on global variables.When Java applets failed, JavaScript became the language of the Web by default, making its popularity almost completely independent of its qualities as a programming language. In JavaScript: The Good Parts, Crockford finally digs through the steaming pile of good intentions and blunders to give you a detailed look at all the genuinely elegant parts of JavaScript, including:SyntaxObjectsFunctionsInheritanceArraysRegular expressionsMethodsStyleBeautiful featuresThe real beauty? As you move ahead with the subset of JavaScript that this book presents, you'll also sidestep the need to unlearn all the bad parts. Of course, if you want to find out more about the bad parts and how to use them badly, simply consult any other JavaScript book.With JavaScript: The Good Parts, you'll discover a beautiful, elegant, lightweight and highly expressive language that lets you create effective code, whether you're managing object libraries or just trying to get Ajax to run fast. If you develop sites or applications for the Web, this book is an absolute must.

    The book is a complete revision of the commands section of Sobell's Practical Guide to Linux - a proven best-seller. The book is Linux distribution and release agnostic. It will appeal to users of ALL Linux distributions. Superior examples make this book the the best option on the market! System administrators, software developers, quality assurance engineers and others working on a Linux system need to work from the command line in order to be effective. Linux is famous for its huge number of command line utility programs, and the programs themselves are famous for their large numbers of options, switches, and configuration files. But the truth is that users will only use a limited (but still significant) number of these utilities on a recurring basis, and then only with a subset of the most important and useful options, switches and configuration files. This book cuts through all the noise and shows them which utilities are most useful, and which options most important. And it contains examples, lot's and lot's of examples. programmability. Utilities are designed, by default, to work wtih other utilities within shell programs as a way of automating system tasks. This book contains a superb introduction to Linux shell programming. And since shell programmers need to write their programs in text editors, this book covers the two most popular ones: vi and emacs.

    But I don't think I've seen a better resource for the lay user than this one. T. Ormiston-smith. Mother Nature's medicine cabinet. In ancient times, the plant kingdom provided our earliest ancestors with the natural healing powers derived from nature. Extracts and essences from plants and flowers were prized for their medicinal, spiritual, aromatic, and therapeutic value, including beauty benefits. Aromatic plants, essences, and oils have traditionally been used during religious ceremonies and observances, beauty care and perfumes, food enhancement, and preservation. Aromatic plants were the basis for herbal and botanical medicines and remedies for thousands of years - they still are. In fact, they’re the root of today’s modern pharmaceuticals. And as lifestyles rapidly changed to meet everyday challenges, and technology progressed in leaps and bounds, herbal knowledge soon fell by the wayside. During the past century, as the side effects of many chemically based drugs come to light - not to mention the exuberant costs, natural healing has come full circle and has gradually found its way back into our homes. The Western World is standing up and taking notice. People are educating themselves about the wonderful uses and benefits of using essential oils, herbs, and spices. Mother nature's medicine cabinet is back, invoking endless remedies and in some cases, cures - without the side effects. Granted. Natural healing may not replace the family doctor or chemically manufactured drugs entirely, but it certainly is a healthy alternative to consider when thinking about your health, beauty, wellbeing, and fitness regime. Bonus: Includes Medicinal Herbs and their uses. Discover the many benefits to diffusing essential oils to achieve optimal health and well-being in your home and workplace. Diffusing essential oils can help you study better, sleep better, enhance your moods and put you in the mood... Essential oils and pregnancy. Essential oils and children. There is also a section about essential oils for pets – which ones to use and which ones to avoid.

    “Big data” refers to our burgeoning ability to crunch vast collections of information, analyze it instantly, and draw sometimes profoundly surprising conclusions from it. This emerging science can translate myriad phenomena—from the price of airline tickets to the text of millions of books—into searchable form, and uses our increasing computing power to unearth epiphanies that we never could have seen before. A revolution on par with the Internet or perhaps even the printing press, big data will change the way we think about business, health, politics, education, and innovation in the years to come. It also poses fresh threats, from the inevitable end of privacy as we know it to the prospect of being penalized for things we haven’t even done yet, based on big data’s ability to predict our future behavior.In this brilliantly clear, often surprising work, two leading experts explain what big data is, how it will change our lives, and what we can do to protect ourselves from its hazards. Big Data is the first big book about the next big thing.www.big-data-book.com

    Together, they ruled big business. They transformed popular culture. And they provoked a national controversy.

    When Dr Ben Goldacre saw someone on daytime TV dipping her feet in an 'Aqua Detox' footbath, releasing her toxins into the water, turning it brown, he thought he'd try the same at home. 'Like some kind of Johnny Ball cum Witchfinder General', using his girlfriend's Barbie doll, he gently passed an electrical current through the warm salt water. It turned brown. In his words: 'before my very eyes, the world's first Detox Barbie was sat, with her feet in a pool of brown sludge, purged of a weekend's immorality.' Dr Ben Goldacre is the author of the Bad Science column in the Guardian. His book is about all the 'bad science' we are constantly bombarded with in the media and in advertising. At a time when science is used to prove everything and nothing, everyone has their own 'bad science' moments from the useless pie-chart on the back of cereal packets to the use of the word 'visibly' in cosmetics ads.

    The algorithms you'll use most often as a programmer have already been discovered, tested, and proven.
