Build robust and highly scalable web applications with Google App EngineAbout This BookGet an in-depth look at how Google App Engine works under the hoodDesign and model your application around Google's highly scalable distributed NoSQL datastore to unlock its full potentialA comprehensive guide to ensure your mastery of Google App Engine Who This Book Is For If you have been developing web applications in Python or any other dynamic language but have always wondered how to write highly scalable web applications without getting into system administration and other plumbing, then this is the book for you. No experience in writing scalable applications is required.What You Will LearnScale and develop your applications with Google App Engine's runtime environmentGet to grips with request handling mechanism and write request handlersDeep dive into Google's distributed NoSQL and highly scalable datastore and design your application around itImplement powerful search with scalable datastorePerform long-running tasks in the background using task queuesWrite compartmentalized apps using multi tenancy, memcache, and other Google App Engine runtime servicesHandle web requests using the CGI, WSGI, and multi-threaded configurationsDeploy, tweak, and manage apps in production on Google App Engine In Detail Developing web applications that serve millions of users is no easy task, as it involves a number of configurations and administrative tasks for the underlying software and hardware stack. This whole configuration requires not only expertise, but also a fair amount of time as well. Time that could have been spent on actual application functionality. Google App Engine allows you develop highly scalable web applications or backends for mobile applications without worrying about the system administration plumbing or hardware provisioning issues. Just focus writing on your business logic, the meat of the application, and let Google's powerful infrastructure scale it to thousands of requests per second and millions of users without any effort on your part. This book takes you from explaining how scalable applications work to designing and developing robust scalable web applications of your own, utilizing services available on Google App Engine. Starting with a walkthrough of scalability is and how scalable web applications work, this book introduces you to the environment under which your applications exist on Google App Engine. Next, you will learn about Google's datastore, which is a massively scalable distributed NoSQL solution built on top of BigTable. You will examine the BigTable concepts and operations in detail and reveal how it is used to build Google datastore. Armed with this knowledge, you will then advance towards how to best model your data and query that along with transactions. To augment the powerful distributed dataset, you will deep dive into search functionality offered on Google App Engine. With the search and storage sorted out, you will get a look into performing long running tasks in the background using Google App Engine task queues along with sending and receiving emails. You will also examine the memcache to boost web application performance, image processing for common image manipulation tasks. You will then explore uploading, storing, and serving large files using Blobstore and Cloud storage. Finally, you will be presented with the deployment and monitoring of your applications in production along with a detailed look at dividing applications into different working modules.Style and approach This book is an in-depth guide where you will examine the problems in the context of highly scalable web applications. This book will take you through the libraries, services, and required configuration and finally puts everything together into a small web application that showcases all the capabilities of Google App Engine.

His study leads to his own death -- and to the author timeless investigation into the nature of love and the meaning of the human condition. The Bridge of San Luis Rey is now reissued in this handsome hardcover edition featuring a new foreword by Russell Banks. Tappan Wilder has written an engaging and thought-provoking afterword, which includes unpublished notes for the Pulitzer Prize winning novel, illuminating photographs, and other remarkable documentary material. Granville Hicks insightful comment about Wilder suggests an inveterate truth: As a craftsman he is second to none, and there are few who have looked deeper into the human heart.

A major historical novel from "one of the great artistic forces of our time" (The Nation ) an eerie, unforgettable story of possession, power, and loss in early-twentieth-century Princeton, a cultural crossroads of the powerful and the damned Princeton, New Jersey, at the turn of the twentieth century: a tranquil place to raise a family, a genteel town for genteel souls. But something dark and dangerous lurks at the edges of the town, corrupting and infecting its residents. Vampires and ghosts haunt the dreams of the innocent. A powerful curse besets the elite families of Princeton; their daughters begin disappearing. A young bride on the verge of the altar is seduced and abducted by a dangerously compelling man a shape-shifting, vaguely European prince who might just be the devil, and who spreads his curse upon a richly deserving community of white Anglo-Saxon privilege. And in the Pine Barrens that border the town, a lush and terrifying underworld opens up. When the bride's brother sets out against all odds to find her, his path will cross those of Princeton's most formidable people, from Grover Cleveland,?fresh out of his second term in the White House and retired to town for a quieter life, to soon-to-be commander in chief Woodrow Wilson,?president of the university?and a complex individual obsessed to the point of madness with his need to retain power; from the young Socialist idealist Upton Sinclair to his charismatic comrade Jack London, and the most famous writer of the era, Samuel Clemens/Mark Twain all plagued by "accursed" visions. An utterly fresh work from Oates, The Accursed marks new territory for the masterful writer. Narrated with her unmistakable psychological insight, it combines beautifully transporting historical detail with chilling supernatural elements to stunning effect.
