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.

    The first edition of this book, Programming Perl, hit the shelves in 1990, and was quickly adopted as the undisputed bible of the language. Since then, Perl has grown with the times, and so has this book.Programming Perl is not just a book about Perl. It is also a unique introduction to the language and its culture, as one might expect only from its authors. Larry Wall is the inventor of Perl, and provides a unique perspective on the evolution of Perl and its future direction. Tom Christiansen was one of the first champions of the language, and lives and breathes the complexities of Perl internals as few other mortals do. Jon Orwant is the editor of The Perl Journal, which has brought together the Perl community as a common forum for new developments in Perl.Any Perl book can show the syntax of Perl's functions, but only this one is a comprehensive guide to all the nooks and crannies of the language. Any Perl book can explain typeglobs, pseudohashes, and closures, but only this one shows how they really work. Any Perl book can say that my is faster than local, but only this one explains why. Any Perl book can have a title, but only this book is affectionately known by all Perl programmers as "The Camel."This third edition of Programming Perl has been expanded to cover version 5.6 of this maturing language. New topics include threading, the compiler, Unicode, and other new features that have been added since the previous edition.

    But while most of us today can work a computer--albeit with the help of the ever-present computer software manual--we know little about what goes on inside the box and virtually nothing about software designor the world of computer programming. In Patterns of Software, the respected software pioneer and computer scientist, Richard Gabriel, gives us an informative inside look at the world of software design and computer programming and the business that surrounds them. In this wide-ranging volume, Gabriel discusses such topics as whatmakes a successful programming language, how the rest of the world looks at and responds to the work of computer scientists, how he first became involved in computer programming and software development, what makes a successful software business, and why his own company, Lucid, failed in 1994, tenyears after its inception. Perhaps the most interesting and enlightening section of the book is Gabriel's detailed look at what he believes are the lessons that can be learned from architect Christopher Alexander, whose books--including the seminal A Pattern Language--have had a profound influence on the computer programmingcommunity. Gabriel illuminates some of Alexander's key insights--the quality without a name, pattern languages, habitability, piecemeal growth--and reveals how these influential architectural ideas apply equally well to the construction of a computer program. Gabriel explains the concept ofhabitability, for example, by comparing a program to a New England farmhouse and the surrounding structures which slowly grow and are modified according to the needs and desires of the people who live and work on the farm. Programs live and grow, and their inhabitants--the programmers--need to workwith that program the way the farmer works with the homestead. Although computer scientists and software entrepreneurs will get much out of this book, the essays are accessible to everyone and will intrigue anyone curious about Silicon Valley, computer programming, or the world of high technology.

    Many of these patterns are successful by themselves, but as this practical ebook demonstrates, they provide a more holistic and compelling approach when applied together.Author Ben Stopford explains how service-based architectures and stream processing tools such as Apache Kafka® can help you build business-critical systems.* Learn why streaming beats request-response based architectures in complex, contemporary use cases* Understand why replayable logs such as Kafka provide a backbone for both service communication and shared datasets* Explore how event collaboration and event sourcing patterns increase safety and recoverability with functional, event-driven approaches* Apply patterns including Event Sourcing and CQRS, and how to build multi-team systems with microservices and SOA using patterns such as “inside out databases” and “event streams as a source of truth”* Build service ecosystems that blend event-driven and request-driven interfaces using a replayable log and Kafka's Streams API* Scale beyond individual teams into larger, department- and company-sized architectures, using event streams as a source of truth

    . . . Put this one on your must-have list if you have software, love software, hate programmers, or even ARE a programmer, because Mr. Platt (who teaches programming) has set out to puncture the bloated egos of all those who think that just because they can write a program, they can make it easy to use. . . . This book is funny, but it is also an important wake-up call for software companies that want to reduce the size of their customer support bills. If you were ever stuck for an answer to the question, 'Why do good programmers make such awful software?' this book holds the answer."--John McCormick, Locksmith columnist, TechRepublic.com "I must say first, I don't get many computing manuscripts that make me laugh out loud. Between the laughs, Dave Platt delivers some very interesting insight and perspective, all in a lucid and engaging style. I don't get much of that either!"--Henry Leitner, assistant dean for information technology andsenior lecturer on computer science, Harvard University "A riotous book for all of us downtrodden computer users, written in language that we understand."--Stacy Baratelli, author's barber "David's unique take on the problems that bedevil software creation made me think about the process in new ways. If you care about the quality of the software you create or use, read this book."--Dave Chappell, principal, Chappell & Associates "I began to read it in my office but stopped before I reached the bottom of the first page. I couldn't keep a grin off my face! I'll enjoy it after I go back home and find a safe place to read."--Tsukasa Makino, IT manager "David explains, in terms that my mother-in-law can understand, why the software we use today can be so frustrating, even dangerous at times, and gives us some real ideas on what we can do about it."--Jim Brosseau, Clarrus Consulting Group, Inc. A Book for Anyone Who Uses a Computer Today...and Just Wants to Scream! Today's software sucks. There's no other good way to say it. It's unsafe, allowing criminal programs to creep through the Internet wires into our very bedrooms. It's unreliable, crashing when we need it most, wiping out hours or days of work with no way to get it back. And it's hard to use, requiring large amounts of head-banging to figure out the simplest operations.It's no secret that software sucks. You know that from personal experience, whether you use computers for work or personal tasks. In this book, programming insider David Platt explains why that's the case and, more importantly, why it doesn't have to be that way. And he explains it in plain, jargon-free English that's a joy to read, using real-world examples with which you're already familiar. In the end, he suggests what you, as a typical user, without a technical background, can do about this sad state of our software--how you, as an informed consumer, don't have to take the abuse that bad software dishes out.As you might expect from the book's title, Dave's expose is laced with humor--sometimes outrageous, but always dead on. You'll laugh out loud as you recall incidents with your own software that made you cry. You'll slap your thigh with the same hand that so often pounded your computer desk and wished it was a bad programmer's face. But Dave hasn't written this book just for laughs. He's written it to give long-overdue voice to your own discovery--that software does, indeed, suck, but it shouldn't.
