The sixth edition of this bestselling Perl tutorial includes recent changes to the language. Years of classroom testing and experience helped shape the book's pace and scope, and this edition is packed with exercises that let readers practice the concepts while they follow the text.
North America faces a transportation crisis. Gas-guzzling SUVs clog the highways and air travelers face delays, cancellations, and uncertainty in the wake of unprecedented terrorist attacks. New Departures closely examines the options for improving intercity passenger trains’ capacity to move North Americans where they want to go. While Amtrak and VIA Rail Canada face intense pressure to transform themselves into successful commercial enterprises, Anthony Perl demonstrates how public policy changes lie behind the triumphs of European and Japanese high-speed rail passenger innovations. Perl goes beyond merely describing these achievements, translating their implications into a North American institutional and political context and diagnosing the obstacles that have made renewing passenger trains so much more difficult in North America than elsewhere. New Departures links the lessons behind rail passenger revitalization abroad with the opportunity to recast the policies that constrain Amtrak and VIA Rail from providing efficient and effective intercity transportation.
From one of our most widely admired art critics comes a bold and timely manifesto reaffirming the independence of all the arts—musical, literary, and visual—and their unique and unparalleled power to excite, disturb, and inspire us. As people look to the arts to promote a particular ideology, whether radical, liberal, or conservative, Jed Perl argues that the arts have their own laws and logic, which transcend the controversies of any one moment. “Art’s relevance,” he writes, “has everything to do with what many regard as its irrelevance.” Authority and Freedom will find readers from college classrooms to foundation board meetings—wherever the arts are confronting social, political, and economic ferment and heated debates about political correctness and cancel culture. Perl embraces the work of creative spirits as varied as Mozart, Michelangelo, Jane Austen, Henry James, Picasso, and Aretha Franklin. He contends that the essence of the arts is their ability to free us from fixed definitions and categories. Art is inherently uncategorizable—that’s the key to its importance. Taking his stand with artists and thinkers ranging from W. H. Auden to Hannah Arendt, Perl defends works of art as adventuresome dialogues, simultaneously dispassionate and impassioned. He describes the fundamental sense of vocation—the engagement with the tools and traditions of a medium—that gives artists their purpose and focus. Whether we’re experiencing a poem, a painting, or an opera, it’s the interplay between authority and freedom—what Perl calls “the lifeblood of the arts”—that fuels the imaginative experience. This book will be essential reading for everybody who cares about the future of the arts in a democratic society.
Many neophyte programmers now begin their careers by learning the metalanguage, Perl. But the books currently available on Perl assume their readers already understand the basics of writing and designing programs--when in fact they do not. The tutorial teaches programming right along with the particulars of Perl syntax, as well as good style and structure and maintainability of the code.
Want to learn how to program and think like a computer scientist? This practical guide gets you started on your programming journey with the help of Perl 6, the younger sister of the popular Perl programming language. Ideal for beginners, this hands-on book includes over 100 exercises with multiple solutions, and more than 1,000 code examples so you can quickly practice what you learn. Experienced programmers--especially those who know Perl 5--will also benefit. Divided into two parts, Think Perl 6 starts with basic concepts that every programmer needs to know, and then focuses on different programming paradigms and some more advanced programming techniques. With two semesters' worth of lessons, this book is the perfect teaching tool for computer science beginners in colleges and universities. Learn basic concepts including variables, expressions, statements, functions, conditionals, recursion, and loops Understand commonly used basic data structures and the most useful algorithms Dive into object-oriented programming, and learn how to construct your own types and methods to extend the language Use grammars and regular expressions to analyze textual content Explore how functional programming can help you make your code simpler and more expressive
