You'll learn how to use Haskell in a variety of practical ways, from short scripts to large and demanding applications. Real World Haskell takes you through the basics of functional programming at a brisk pace, and then helps you increase your understanding of Haskell in real-world issues like I/O, performance, dealing with data, concurrency, and more as you move through each chapter. With this book, you will:Understand the differences between procedural and functional programming Learn the features of Haskell, and how to use it to develop useful programs Interact with filesystems, databases, and network services Write solid code with automated tests, code coverage, and error handling Harness the power of multicore systems via concurrent and parallel programming You'll find plenty of hands-on exercises, along with examples of real Haskell programs that you can modify, compile, and run. Whether or not you've used a functional language before, if you want to understand why Haskell is coming into its own as a practical language in so many major organizations, Real World Haskell is the best place to start.

    Focus is on an in-depth analysis and exposition of not-so-obvious coding errors in the sample code provided. The theme is to answer the questions 'How couild I have automatically detected this bug' and 'How could I have prevented this bug'? Chapters include programmer attitudes, techniques and debugging methodology. A particularly revealing chapter is "Treacheries of the Trade", should be required reading for all C maniacs. The author has been a professional programmer for seventeen years and draws heavily (and candidly) on actual coding problems and practices based on years of experience at Microsoft.

    With this practical guide, Alex Banks and Eve Porcello deliver a clear learning path for frontend web developers, backend engineers, and project and product managers looking to get started with GraphQL.You'll explore graph theory, the graph data structure, and GraphQL types before learning hands-on how to build a schema for a photo-sharing application. This book also introduces you to Apollo Client, a popular framework you can use to connect GraphQL to your user interface.Explore graph theory and review popular graph examples in use todayLearn how GraphQL applies database querying methods to the internetCreate a schema for a PhotoShare application that serves as a roadmap and a contract between the frontend and backend teamsUse JavaScript to build a fully functioning GraphQL service and Apollo to implement a clientLearn how to prepare GraphQL APIs and clients for production

    This book helps you use SQL and Excel to extract business information from relational databases and use that data to define business dimensions, store transactions about customers, produce results, and more. Each chapter explains when and why to perform a particular type of business analysis in order to obtain useful results, how to design and perform the analysis using SQL and Excel, and what the results should look like.

    Currently, Lua is being used in areas ranging from embedded systems to Web development and is widely spread in the game industry, where knowledge of Lua is an indisputable asset. "Programming in Lua" is the official book about the language, giving a solid base for any programmer who wants to use Lua. Authored by Roberto Ierusalimschy, the chief architect of the language, it covers all aspects of Lua 5---from the basics to its API with C---explaining how to make good use of its features and giving numerous code examples. "Programming in Lua" is targeted at people with some programming background, but does not assume any prior knowledge about Lua or other scripting languages. This Second Edition updates the text to Lua 5.1 and brings substantial new material, including numerous new examples, a detailed explanation of the new module system, and two new chapters centered on multiple states and garbage collection.

    Aiming to tell the dark secrets of computer arithmetic, this title is suitable for library developers, compiler writers, and lovers of elegant hacks.

    MyLiteratureLab icons are found in the margins of the text along with a list of media assets at the front of the anthology. The most popular Literature anthology continues to bring students the finest literature from fables to poetweets. The Twelfth Edition of "Literature: An Introductiuon to Fiction, Poetry, Drama, and Writing," edited" "by X. J. Kennedy and Dana Gioia, includes eleven new stories from students' favorite authors: ZZ Packer's "Brownies," Ray Bradbury's, "The Sound of Thunder," Anne Tyler's, "Teenage Wasteland," David Leavitt's, "A Place I've Never Been" and Isabel Allende's "The Judge's Wife." More than 60 new accessible and engaging poems have been added including former Iraqi soldier Brian Turner's "The Hurt Locker," Katha Pollit's "The Mind-Body Problem" as well as poetweets from Lawrence Bridges and Robert Pinsky. In addition, there are new poems from Kay Ryan, Benjamin Alire Saenz, H. D, Gary Snyder, Joy Harjo, Tami Haaland, Robert Hayden, Denise Levertov, and William Carlos Williams. Three new one-act plays help "ease" students into the study of this genre. The new plays include two comedies-- David Ives's, "Sure Thing" and Jane Martin's "Beauty"--as well as Edward Bok Lee's experimental drama "El Santo Americano." In addition, Milcha Sanchez-Scott's" The Cuban Swimmer "has been added." "

    It has been developed in response to the need for a text that supports the mastery of this difficult subject. Therefore, in addition to presenting electromagnetics in a concise and logical manner, the text includes end-of-section review questions, worked examples, boxed remarks that alert students to key ideas and tricky points, margin notes, and point-by-point chapter summaries. Examples and applications invite students to solve problems and build their knowledge of electromagnetics. Application topics include: electric motors, transmission lines, waveguides, antenna arrays and radar systems.

    With problems and solutions. Includes 99 illustrations.

    It also touches upon the fundamentals of 32 bit, and 64 bit advanced processors. The book throughout provides the most popular programming tool - the assembly language codes to enhance the knowledge of programming the processors.Clear and concise in its treatment of topics, the contents of the book is supported by learning tools such as review questions, application examples (case studies) and design-based exercises.
