The Lean Startup
Eric Ries

Most startups fail. But many of those failures are preventable. The Lean Startup is a new approach being adopted across the globe, changing the way companies are built and new products are launched. Eric Ries defines a startup as an organization dedicated to creating something new under conditions of extreme uncertainty. This is just as true for one person in a garage or a group of seasoned professionals in a Fortune 500 boardroom. What they have in common is a mission to penetrate that fog of uncertainty to discover a successful path to a sustainable business. The Lean Startup approach fosters companies that are both more capital efficient and that leverage human creativity more effectively. Inspired by lessons from lean manufacturing, it relies on “validated learning,” rapid scientific experimentation, as well as a number of counter-intuitive practices that shorten product development cycles, measure actual progress without resorting to vanity metrics, and learn what customers really want. It enables a company to shift directions with agility, altering plans inch by inch, minute by minute. Rather than wasting time creating elaborate business plans, The Lean Startup offers entrepreneurs—in companies of all sizes—a way to test their vision continuously, to adapt and adjust before it’s too late. Ries provides a scientific approach to creating and managing successful startups in a age when companies need to innovate more than ever.

UI is Communication - How to Design Intuitive, User Centered Interfaces by Focusing on Effective Communication
Everett N McKay

User interface design is a challenging, multi-disciplinary activity that requires understanding a wide range of concepts and techniques that are often subjective and even conflicting. Imagine how much it would help if there were a single perspective that you could use to simplify these complex issues down to a small set of objective principles. In UI is Communication, Everett McKay explains how to design intuitive user interfaces by focusing on effective human communication. A user interface is ultimately a conversation between users and technology. Well-designed user interfaces use the language of UI to communicate to users efficiently and naturally. They also recognize that there is an emotional human being at the other end of the interaction, so good user interfaces strive to make an emotional connection. Applying what you learn from UI is Communication will remove much of the mystic, subjectiveness, and complexity from user interface design, and help you make better design decisions with confidence. It's the perfect introduction to user interface design. Approachable, practical communication-based guide to interaction and visual design that you can immediately apply to projects to make solid design decisions quickly and confidently Includes design makeovers so you can see the concepts in practice with real examples Communication-based design process ties everything from interaction to visual design together

Clean Code
Robert C. Martin

Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees. Every year, countless hours and significant resources are lost because of poorly written code. But it doesn’t have to be that way. Noted software expert Robert C. Martin, presents a revolutionary paradigm with Clean Code: A Handbook of Agile Software Craftsmanship. Martin, who has helped bring agile principles from a practitioner’s point of view to tens of thousands of programmers, has teamed up with his colleagues from Object Mentor to distill their best agile practice of cleaning code “on the fly” into a book that will instill within you the values of software craftsman, and make you a better programmer―but only if you work at it. What kind of work will you be doing? You’ll be reading code―lots of code. And you will be challenged to think about what’s right about that code, and what’s wrong with it. More importantly you will be challenged to reassess your professional values and your commitment to your craft. Clean Code is divided into three parts. The first describes the principles, patterns, and practices of writing clean code. The second part consists of several case studies of increasing complexity. Each case study is an exercise in cleaning up code―of transforming a code base that has some problems into one that is sound and efficient. The third part is the payoff: a single chapter containing a list of heuristics and “smells” gathered while creating the case studies. The result is a knowledge base that describes the way we think when we write, read, and clean code. Readers will come away from this book understanding How to tell the difference between good and bad code How to write good code and how to transform bad code into good code How to create good names, good functions, good objects, and good classes How to format code for maximum readability How to implement complete error handling without obscuring code logic How to unit test and practice test-driven development What “smells” and heuristics can help you identify bad code This book is a must for any developer, software engineer, project manager, team lead, or systems analyst with an interest in producing better code.

Animal Farm
George Orwell

Animal Farm is a satirical allegorical novella by George Orwell, first published in England on 17 August 1945. The book tells the story of a group of farm animals who rebel against their human farmer, hoping to create a society where the animals can be equal, free, and happy. Ultimately, the rebellion is betrayed, and the farm ends up in a state as bad as it was before, under the dictatorship of a pig named Napoleon. According to Orwell, the fable reflects events leading up to the Russian Revolution of 1917 and then on into the Stalinist era of the Soviet Union. Orwell, a democratic socialist, was a critic of Joseph Stalin and hostile to Moscow-directed Stalinism, an attitude that was critically shaped by his experiences during the May Days conflicts between the POUM and Stalinist forces during the Spanish Civil War. The Soviet Union had become a totalitarian autocracy built upon a cult of personality while engaging in the practice of mass incarcerations and secret summary trials and executions. In a letter to Yvonne Davet, Orwell described Animal Farm as a satirical tale against Stalin ("un conte satirique contre Staline"), and in his essay "Why I Write" (1946), wrote that Animal Farm was the first book in which he tried, with full consciousness of what he was doing, "to fuse political purpose and artistic purpose into one whole". The original title was Animal Farm: A Fairy Story, but U.S. publishers dropped the subtitle when it was published in 1946, and only one of the translations during Orwell's lifetime kept it. Other titular variations include subtitles like "A Satire" and "A Contemporary Satire". Orwell suggested the title Union des républiques socialistes animales for the French translation, which abbreviates to URSA, the Latin word for "bear", a symbol of Russia. It also played on the French name of the Soviet Union, Union des républiques socialistes soviétiques.

Fahrenheit 451 - A Novel
Ray Bradbury

Celebrate the fiftieth anniversary of this timeless classic with a special edition featuring a new introduction by the author and a message that is more relevant today than when it was first published. Since the late 1940s, Ray Bradbury has been revered for his works of science fiction and fantasy. With more than five million copies in print, Fahrenheit 451 -- originally published in 1953 -- remains his most acclaimed work. Fahrenheit 451 is the temperature at which book paper burns. Fahrenheit 451 is a novel set in the (perhaps near) future when "firemen" burn books forbidden by a totalitarian "brave new world" regime. The hero, according to Mr. Bradbury, is "a book burner who suddenly discovers that books are flesh-and-blood ideas and cry out silently when put to the torch." Today, when libraries and schools in this country and all over the world are still "burning" certain books, Fahrenheit 451 remains a brilliantly readable and suspenseful work of even greater impact and timeliness.

1984
George Orwell

1984, published in 1949, is a dystopian and satirical novel. It revolves around Winston Smith, who lives in a nation called Oceania, in a province called Airstrip One, which represents present-day England. This state is controlled by the Party, headed by a mysterious leader who is addressed as Emmanuel Goldstein, also known as the Big Brother. The Party watches every single move that Smith and other citizens make. The nation's language and history is forcefully changed for the benefit of the Party. A new language, Newspeak, is being compulsively implemented to ensure works that have anything to do with political rebellion are omitted. In Oceania, even rebellious thoughts are illegal and are said to be the worst of all crimes. The people are suppressed and any form of individuality is not tolerated, including love and sex. Smith works as a low-ranking member of the Party who alters historical records. He hates the Party and thus buys an illegal diary in which he pens down his thoughts. He meets Julia, a coworker, who seems to been romantically inclined towards him. He however doubts that she is a Party spy who will get him imprisoned for his 'thoughtcrimes'. Her love turns out to be true and they have a covert affair. Smith's hatred for the Party grows day by day and he is convinced that a powerful Party official O'Brien is actually trying to overthrow the present government with the help of a secret group named the Brotherhood. As the story goes on, readers learn the twists and turns that life in Oceania has in store for Smith. He faces terror, betrayal, freedom, and a broken spirit. 1984 is the author's haunting vision of the future. The book has been adapted into television programmes, films, radio broadcasts and plays. In 2003, the book was number 8 on BBC's survey The Big Read. It was 6th and 13th on the reader's and editor's list of Modern Library 100 Best Novels, respectively. In 2005, it was added to the 100 Best English Language Novel from 1923 to 2005 by TIME magazine. ABOUT THE AUTHOR: Eric Arthur Blair, better known by his pen name George Orwell (1903-1950), was an English author and journalist. His work is marked by keen intelligence and wit, a profound awareness of social injustice, an intense opposition to totalitarianism, a passion for clarity in language, and a belief in democratic socialism. In addition to his literary career Orwell served as a police officer with the Indian Imperial Police in Burma from 1922-1927 and fought with the Republicans in the Spanish Civil War from 1936-1937. He was severely wounded when he was shot through his throat. Orwell and his wife were accused of 'Rabid Trotskyism' and tried in absentia in Barcelona, along with other leaders of the POUM, in 1938. However by then they had escaped from Spain and returned to England. Between 1941 and 1943, Orwell worked on propaganda for the BBC. In 1943, he became literary editor of the Tribune, a weekly left-wing magazine. He was a prolific polemical journalist, article writer, literary critic, reviewer, poet and writer of fiction, and considered perhaps the twentieth century's best chronicler of English culture. Orwell is best known for the dystopian novel Nineteen Eighty-Four (published in 1949) and the satirical novella Animal Farm (1945)-they have together sold more copies than any two books by any other twentieth-century author. His 1938 book Homage to Catalonia, an account of his experiences as a volunteer on the Republican side during the Spanish Civil War, together with numerous essays on politics, literature, language, and culture, are widely acclaimed. In 2008, The Times ranked him second on a list of 'The 50 greatest British writers since 1945'.

It is the "twilight of the shrinks". Disciples of Freud and Jung sandbag against the rising tide of new age therapies and wring their hands over the unreliable narratives of patients who "lie" on the couch. Managed health care threatens the very future of practice. The contemporary therapist has much to worry about: patients who seduce their therapists with money, sex, fanatical devotion - and all the other deadly sins in a game of musical chairs around the seat of power in the therapeutic session. In a daring spin on his lifelong devotion to chart the inner lives of patients in his intimate case histories, Dr. Yalom now turns the tables on the other half of the therapeutic relationship - the therapist from an age of secrets, who "interprets" the boundaries of sexual propriety. Or Marshal, haunted by his own obsessive-compulsive behaviors, uncertain of the role of money in his relationship with patients. And finally, there is Ernest Lash, who, saved ultimately by his sincere desire to help people, risks a totally open, authentic relationship with a patient and assumes that to be healing in and of itself. Their stories are rendered here with great affection and ruthless recognition.

With an Introduction by Peter Dunwoodie; translated by Matthew Ward. Behind the subterfuge, Camus explores what he termed "the nakedness of man faced with the absurd" and describes the condition of reckless alienation and spiritual exhaustion that characterized so much of twentieth-century life. “The Stranger is a strikingly modern text and Matthew Ward’s translation will enable readers to appreciate why Camus’s stoical anti-hero and devious narrator remains one of the key expressions of a postwar Western malaise, and one of the cleverest exponents of a literature of ambiguity.” –from the Introduction by Peter Dunwoodie First published in 1946; now in translation by Matthew Ward.
