    We start off easy, defining some of the tech lingo you may have heard before, but didn’t fully understand. From there, each lesson introduces something new, slowly building up to the point where you are confident about what an API is and, for the brave, could actually take a stab at using one.

    These kids often have violent outbursts, steal, engage in outlandish lying, play with feces, and hoard food. They are broken children who too often break even the most loving of caregivers. Many parents of these children feel utterly isolated as family, friends, and professionals minimize their struggles. Reactive Attachment Disorder (RAD) - The Essential Guide for Parents is written by a parent who is in the trenches with you. Keri has lived the journey of raising a son with RAD and has navigated the mental health system for over a decade. This is the resource you’ve been waiting for – you won’t find platitudes or false hopes. What you will find is essential information, practical suggestions, and resource recommendations to provide a way forward. If you desperately need help navigating the difficult RAD journey with your child, this book is for you.

    Unlike the rest of the world's archipelagoes, it still has 95 percent of its prehuman quota of species. Wildlife of the Galapagos is the most superbly illustrated and comprehensive identification guide ever to the natural splendor of these incomparable islands--islands today threatened by alien species and diseases that have diminished but not destroyed what so enchanted Darwin on his arrival there in 1835. Covering over 200 commonly seen birds, mammals, reptiles, invertebrates, and plants, it reveals the archipelago's striking beauty through more than 400 color photographs, maps, and drawings and well-written, informative text. While the Galapagos Giant Tortoise, the Galapagos Sea Lion, and the Flightless Cormorant are recognized the world over, these thirty-three islands--in the Pacific over 600 miles from mainland Ecuador--are home to many more unique but less famous species. Here, reptiles well outnumber mammals, for they were much better at drifting far from a continent the archipelago was never connected with; the largest native land mammals are rice rats. The islands' sixty resident bird species include the only penguin to breed entirely in the tropics and to inhabit the Northern Hemisphere. There is a section offering tips on photography in the Equatorial sunlight, and maps of visitors' sites as well as information on the archipelago's history, climate, geology, and conservation. Wildlife of the Galapagos is the perfect companion for anyone who wants to know what so delighted Darwin. Covers over 200 commonly seen species including birds, mammals, reptiles, invertebrates, plants, and coastal and marine life Illustrated with over 400 color photographs, maps, and drawings; includes maps of visitors' sites Written by wildlife experts with extensive knowledge of the area Includes information on the history, climate, geology, and conservation of the islands The most complete identification guide to the wildlife of the Galapagos

    We'll use the world's most popular functional programming language: JavaScript. Some may feel this is a poor choice as it's against the grain of the current culture which, at the moment, feels predominately imperative. However, I believe it is the best way to learn FP for several reasons:You likely use it every day at work.This makes it possible to practice and apply your acquired knowledge each day on real world programs rather than pet projects on nights and weekends in an esoteric FP language.We don't have to learn everything up front to start writing programs.In a pure functional language, you cannot log a variable or read a DOM node without using monads. Here we can cheat a little as we learn to purify our codebase. It's also easier to get started in this language since it's mixed paradigm and you can fall back on your current practices while there are gaps in your knowledge.The language is fully capable of writing top notch functional code.We have all the features we need to mimic a language like Scala or Haskell with the help of a tiny library or two. Object-oriented programming currently dominates the industry, but it's clearly awkward in JavaScript. It's akin to camping off of a highway or tap dancing in galoshes. We have to bind all over the place lest this change out from under us, we don't have classes[^Yet], we have various work arounds for the quirky behavior when the new keyword is forgotten, private members are only available via closures. To a lot of us, FP feels more natural anyways.That said, typed functional languages will, without a doubt, be the best place to code in the style presented by this book. JavaScript will be our means of learning a paradigm, where you apply it is up to you. Luckily, the interfaces are mathematical and, as such, ubiquitous. You'll find yourself at home with swiftz, scalaz, haskell, purescript, and other mathematically inclined environments.

    Many today are well on their way to becoming a sad statistic in the war on obesity, high blood sugar, and the related diseases—including diabetes—that can result from a diet that’s seriously out of whack.

    Author Charles H. Roth, Jr. carefully presents the theory that is necessary for understanding the fundamental concepts of logic design while not overwhelming students with the mathematics of switching theory. Divided into 20 easy-to-grasp study units, the book covers such fundamental concepts as Boolean algebra, logic gates design, flip-flops, and state machines. By combining flip-flops with networks of logic gates, students will learn to design counters, adders, sequence detectors, and simple digital systems. After covering the basics, this text presents modern design techniques using programmable logic devices and the VHDL hardware description language.

    Completely updated to comprehensively reflect the most recent changes to the ISTQB Foundation Syllabus, the book adopts a practical, hands-on approach, covering the fundamental topics that every system and software tester should know. The authors are themselves developers of the ISTQB syllabus and are highly respected international authorities, teachers and authors within the field of software testing.

    But in the scalp of a balding man, they do not get everything they need and as a result, the hair-producing cells gradually die off. Here we have an example of a mild ‘disease’ which is caused by cellular malnutrition.” —Dr. Roger J. Williams “A living cell requires energy not only for all of its functions, but also for maintenance of its structure.” —Nobel Laureate Albert Szent-Györgyi "What could be more important to understand than biological energy? Thought, growth, movement, every philosophical and practical issue involves the nature of biological energy.” —Raymond Peat, PhD ======== The Current View of Pattern Hair Loss is Unproductive (and Dangerous) While it is often stated with great confidence that pattern pattern hair loss is the result of defective genes and "male" androgenic hormones (e.g., dihydrotestosterone or DHT), the theory is physiologically unsound. After 60 years of research the "genetic-androgen" hypoheses has produced a single FDA-approved "therapy" that works less than 50% the time and can result in permanent chemical castration (Minoxidil is a nonstarter for many men and women). In contrast, castrates and pseudohermaphrodites--who serve as the foundation for all baldness research--are protected from pattern hair loss 100% of the time. Steps Towards a 'Bioenergetic' View of Pattern Hair Loss Standing on the shoulders of giants (e.g., Otto Warburg, Albert Szent-Györgyi, Gilbert Ling, Ray Peat and others), HAIR LIKE A FOX sets up an alternative 'bioenergetic model' of pattern hair loss with a focus on the smallest unit of life, the cell. This same context elucidates simple yet effective therapies for halting and perhaps reversing pattern hair loss in a way that harmonizes with our unique physiology.
