    In Running to Extremes, she attempts to answer that question and many more about ultramarathon running. In the past few years, Lisa has taken part in some of the most gruelling races on earth. Not content with having run the Badwater Ultramarathon once, she's been back and done it a second time. She's also completed the Gobi March and a race in the Egyptian Sahara. However, none of these could have prepared her for her greatest challenge to date: La Ultra, a 222-kilometre non-stop race over two Himalayan mountain passes. Running to Extremes tells the stories behind these races and provides plenty of advice for runners of all levels and distances. Filled with training tips, gear lists, information on nutrition and supplements, advice on mental preparation and, most importantly, a focus on how to keep yourself healthy while training and racing, it will inspire and motivate runners and non-runners alike.

    Yet lost are the stories on the other side of these history-making moments, the athletes who experienced not transcendent glory but crushing disappointment: the cornerback who missed the tackle on the big touchdown; the relief pitcher who lost the series; the world-record holding Olympian who fell on the ice.In Losing Isn’t Everything, famed sportscaster Curt Menefee, joined by bestselling writer Michael Arkush, examines a range of signature "disappointments" from the wide world of sports, interviewing the subject at the heart of each loss and uncovering what it means—months, years, or decades later—to be associated with failure. While history is written by the victorious, Menefee argues that these moments when an athlete has fallen short are equally valuable to sports history, offering deep insights into the individuals who suffered them and about humanity itself.Telling the losing stories behind such famous moments as the Patriots’ Rodney Harrison guarding the Giants' David Tyree during the "Helmet Catch" in Super Bowl XLII, Mary Decker’s fall in the 1984 Olympic 1500m, and Craig Ehlo who gave up "The Shot" to Michael Jordan in the 1989 NBA playoffs, Menefee examines the legacy of the hardest loses, revealing the unique path that athletes have to walk after they lose on their sport’s biggest stage. Shedding new light some of the most accepted scapegoat stories in the sports cannon, he also revisits both the Baltimore Colts' loss to the Jets in Super Bowl III, as well as the Red Sox loss in the 1986 World Series, showing why, despite years of humiliation, it might not be all Bill Buckner's fault.Illustrated with sixteen pages of color photos, this considered and compassionate study offers invaluable lessons about pain, resilience, disappointment, remorse, and acceptance that can help us look at our lives and ourselves in a profound new way.

    Web Development With Clojure shows you how to apply Clojure programming fundamentals to build real-world solutions. You'll develop all the pieces of a full web application in this powerful language. If you already have some familiarity with Clojure, you'll learn how to put it to serious practical use. If you're new to the language, the book provides just enough Clojure to get down to business.You'll learn the full process of web development using Clojure while getting hands-on experience with current tools, libraries, and best practices in the language. You'll develop Clojure apps with both the Light Table and Eclipse development environments. Rather than frameworks, Clojure development builds on rich libraries. You'll acquire expertise in the popular Ring/Compojure stack, and you'll learn to use the Liberator library to quickly develop RESTful services. Plus, you'll find out how to use ClojureScript to work in one language on the client and server sides.Throughout the book, you'll develop key components of web applications, including multiple approaches to database access. You'll create a simple guestbook app and an app to serve resources to users. By the end, you will have developed a rich Picture Gallery web application from conception to packaging and deployment.This book is for anyone interested in taking the next step in web development.Q&A with Dmitri SotnikovWhy did you write Web Development with Clojure?When I started using Clojure, I found that it took a lot of work to find all the pieces needed to put together a working application. There was very little documentation available on how to organize the code, what libraries to use, or how to package the application for deployment. Having gone through the process of figuring out what works, I thought that it would be nice to make it easier for others to get started.What are the advantages of using a functional language?Over the course of my career, I have developed a great appreciation for functional programming. I find that it addresses a number of shortcomings present in the imperative paradigm. For example, in a functional language any changes to the data are created via revisions to the existing data. So they only exist in the local scope. This fact allows us to safely reason about individual parts of the program in isolation, which is critical for writing and supporting large applications.Why use Clojure specifically?Clojure is a simple and pragmatic language that is designed for real-world usage. It combines the productivity of a high-level language with the excellent performance seen in languages like C# or Java. It's also very easy to learn because it allows you to use a small number of concepts to solve a large variety of problems.If I already have a preferred web development platform, what might I get out of this book?If you're using an imperative language, you'll get to see a very different approach to writing code. Even if you're not going to use Clojure as your primary language, the concepts you'll learn will provide you with new ways to approach problems.Is the material in the book accessible to somebody who is not familiar with Clojure?Absolutely. The book targets developers who are already familiar with the basics of web development and are interested in learning Clojure in this context. The book introduces just enough of the language to get you productive and allows you to learn by example.
