Download or read book Scala for the Impatient written by Cay S. Horstmann and published by Pearson Education. This book was released on 2012-03-08 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scala is a modern programming language for the Java Virtual Machine (JVM) that combines the best features of object-oriented and functional programming languages. Using Scala, you can write programs more concisely than in Java, as well as leverage the full power of concurrency. Since Scala runs on the JVM, it can access any Java library and is interoperable with Java frameworks. Scala for the Impatient concisely shows developers what Scala can do and how to do it. In this book, Cay Horstmann, the principal author of the international best-selling Core Java™, offers a rapid, code-based introduction that’s completely practical. Horstmann introduces Scala concepts and techniques in “blog-sized” chunks that you can quickly master and apply. Hands-on activities guide you through well-defined stages of competency, from basic to expert. Coverage includes Getting started quickly with Scala’s interpreter, syntax, tools, and unique idioms Mastering core language features: functions, arrays, maps, tuples, packages, imports, exception handling, and more Becoming familiar with object-oriented programming in Scala: classes, inheritance, and traits Using Scala for real-world programming tasks: working with files, regular expressions, and XML Working with higher-order functions and the powerful Scala collections library Leveraging Scala’s powerful pattern matching and case classes Creating concurrent programs with Scala actors Implementing domain-specific languages Understanding the Scala type system Applying advanced “power tools” such as annotations, implicits, and delimited continuations Scala is rapidly reaching a tipping point that will reshape the experience of programming. This book will help object-oriented programmers build on their existing skills, allowing them to immediately construct useful applications as they gradually master advanced programming techniques.

Perl advocates boast that ""There's More Than One Way To Do It,"" but do you really want to learn several ways of saying the same thing to a computer? To make Perl more accessible, Dr. Tim Maher has over the years designed and taught an essential subset of the language that is smaller, yet practical and powerful. With this engaging book you can now benefit from ""Minimal Perl,"" even if all you know about Unix is grep. You will learn how to write simple Perl commands-many just one-liners-that go far beyond the limitations of Unix utilities, and those of Linux, MacOS/X, etc. And you'll acquire the more advanced Perl skills used in scripts by capitalizing on your knowledge of related Shell resources.

Download or read book Forty one False Starts written by Janet Malcolm and published by Farrar, Straus and Giroux. This book was released on 2013-05-07 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: A National Book Critics Circle Finalist for Criticism A deeply Malcolmian volume on painters, photographers, writers, and critics. Janet Malcolm's In the Freud Archives and The Journalist and the Murderer, as well as her books about Sylvia Plath and Gertrude Stein, are canonical in the realm of nonfiction—as is the title essay of this collection, with its forty-one "false starts," or serial attempts to capture the essence of the painter David Salle, which becomes a dazzling portrait of an artist. Malcolm is "among the most intellectually provocative of authors," writes David Lehman in The Boston Globe, "able to turn epiphanies of perception into explosions of insight." Here, in Forty-one False Starts, Malcolm brings together essays published over the course of several decades (largely in The New Yorker and The New York Review of Books) that reflect her preoccupation with artists and their work. Her subjects are painters, photographers, writers, and critics. She explores Bloomsbury's obsessive desire to create things visual and literary; the "passionate collaborations" behind Edward Weston's nudes; and the character of the German art photographer Thomas Struth, who is "haunted by the Nazi past," yet whose photographs have "a lightness of spirit." In "The Woman Who Hated Women," Malcolm delves beneath the "onyx surface" of Edith Wharton's fiction, while in "Advanced Placement" she relishes the black comedy of the Gossip Girl novels of Cecily von Zeigesar. In "Salinger's Cigarettes," Malcolm writes that "the pettiness, vulgarity, banality, and vanity that few of us are free of, and thus can tolerate in others, are like ragweed for Salinger's helplessly uncontaminated heroes and heroines." "Over and over," as Ian Frazier writes in his introduction, "she has demonstrated that nonfiction—a book of reporting, an article in a magazine, something we see every day—can rise to the highest level of literature." One of Publishers Weekly's Best Nonfiction Books of 2013

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 ofThe 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.
