The book focuses on techniques of lasting value and explains them precisely in terms of a simple abstract machine. The book presents all major programming paradigms in a uniform framework that shows their deep relationships and how and where to use them together.After an introduction to programming concepts, the book presents both well-known and lesser-known computation models ("programming paradigms"). Each model has its own set of techniques and each is included on the basis of its usefulness in practice. The general models include declarative programming, declarative concurrency, message-passing concurrency, explicit state, object-oriented programming, shared-state concurrency, and relational programming. Specialized models include graphical user interface programming, distributed programming, and constraint programming. Each model is based on its kernel language—a simple core language that consists of a small number of programmer- significant elements. The kernel languages are introduced progressively, adding concepts one by one, thus showing the deep relationships between different models. The kernel languages are defined precisely in terms of a simple abstract machine. Because a wide variety of languages and programming paradigms can be modeled by a small set of closely related kernel languages, this approach allows programmer and student to grasp the underlying unity of programming. The book has many program fragments and exercises, all of which can be run on the Mozart Programming System, an Open Source software package that features an interactive incremental development environment.

    This is necessary because, in the words of Michael Polanyi, "we can know more than we can tell." Our design choices are not the result of an ineluctable chain of logic; they come from a deeper place, one which is visceral and inarticulate.Polanyi calls this "tacit knowledge", a thing which we only understand as part of something else. When we speak, we do not focus on making sounds, we focus on our words. We understand the muscular act of speech, but would struggle to explain it.To write software, we must learn where to draw boundaries. Good software is built through effective indirection. We seem to have decided that this skill can only be learned through practice; it cannot be taught, except by example. Our decisions may improve with time, but not our ability to explain them. It's true that the study of these questions cannot yield a closed-form solution for judging software design. We can make our software simple, but we cannot do the same to its problem domain, its users, or the physical world. Our tacit knowledge of this environment will always inform our designs.This doesn't mean that we can simply ignore our design process. Polanyi tells us that tacit knowledge only suffices until we fail, and the software industry is awash with failure. Our designs may never be provably correct, but we can give voice to the intuition that shaped them. Our process may always be visceral, but it doesn't have to be inarticulate.And so this book does not offer knowledge, it offers clarity. It is aimed at readers who know Clojure, but struggle to articulate the rationale of their designs to themselves and others. Readers who use other languages, but have a passing familiarity with Clojure, may also find this book useful.

    I'd love to just get this guide out there in response!” - Heather "Anish" Anderson. 2019 National Geographic Adventurer of the Year, and author of Thirst: 2600 Miles to Home“Have you read Rolf Potts' Vagabonding? It feels a bit like the American Vagabonding.” - Six2 - Pacific Crest and Appalachian Trail Alum.“Gosh I love your book! I'm trying to read it, but for some reason I can't stop crying!!! It resonates so much and I feel so emotional about it.” - Kathy Vaughan, Team UltraPedestrian and co-author of 98 Days of Wind: The Greatest Fail of Our Life“You’re going to have to change the name if you want anyone to pick up your book who doesn’t consider themselves a “dirtbag,” “trash,” or a “bum.”” - Random stranger on Facebook who is not impressed with the title.Screw picket fences. Live your best life. Sleep in the dirt. While a life of adventure has traditionally been reserved for the rich and the sponsored, to the dirtbag, it's a birthright for the masses. Partly a celebration of an underappreciated subculture of hiker trash, ski bums, and vagabonds, and partly a "how to" guide for adventure on the cheap, The Dirtbag's Guide to Life is the first solid attempt to define an outdoor movement that has taken root in backpacker hostels, long trails, and climbing crags around the world.Distilling personal wisdom and practical lessons from dozens of the world’s most dedicated dirtbags, this book is for anyone who dreams of hitchhiking trips through Patagonia and summers spent trail running in Montana, but who can’t be bothered by mainstream frivolities like expensive clothes and basic hygiene.The book answers important logistical questions about the major barriers to a life centered on adventure, and covers practical topics like financial planning and career strategies. It also digs into the big philosophical questions that long-term dirtbags all eventually wrestle with - like how to manage your most important relationships, how to live as a responsible human being, and how to find meaning when you develop a life centered on playing outside.

    As expected, .NET 4 brings a wealth of new APIs to the base class libraries and several new syntactical constructs to C#. For example, it is now possible to create C# methods that support optional and named arguments. As well, you are able to resolve types completely at runtime using the new dynamic keyword. As far as APIs are concerned, this edition of Pro C# 2010 and the .NET 4 Platform will cover a number of new details, including:• the Dynamic Language Runtime (DLR)• the Task Parallel Library (TPL, including PLINQ)• the ADO.NET Entity Framework (as well as LINQ to EF)• expanded coverage of the Windows Presentation Foundation (WPF) API• improved support for COM interopIf you're checking out this book for the first time, understand that it targets experienced software professionals and students of computer science—so please don't expect three chapters devoted to "variable scope" here! The mission of this text is to provide you with a rock-solid foundation in the C# programming language (including a full discussion of OOP) and the critical aspects of the .NET 4 platform.Once you digest the information presented in the book you hold in your hands, you'll be in a perfect position to apply this knowledge to your specific programming assignments, and you'll be well-equipped to explore the .NET universe on your own terms.Andrew TroelsenMicrosoft MVP, Visual Developer—Visual C#; Microsoft Certified Trainer (MCT)
