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.

    He convinced a crack  group of coders to join him in his quest to make a super-charged, global computer.The Infinite Machine introduces Vitalik’s ingenious idea and unfolds Ethereum’s chaotic beginnings. It then explores the brilliant innovation and reckless greed the platform—an infinitely adaptable foundation for experimentation and new applications—has unleashed and the consequences that resulted as the frenzy surrounding it grew: increased regulatory scrutiny, incipient Wall Street interest, and the founding team’s effort to get the Ethereum platform to scale so it can eventually be  accessible to the masses.Financial journalist and cryptocurrency expert Camila Russo details the wild and often hapless adventures of a team of hippy-anarchists, reluctantly led by an ambivalent visionary, and lays out how this new foundation for the internet will spur both transformation and fraud—turning some into millionaires and others into felons—and revolutionize our ideas about money.

     For decades, technology encouraged people to squander their time and intellect as passive consumers. Today, tech has finally caught up with human potential. In Cognitive Surplus, Internet guru Clay Shirky forecasts the thrilling changes we will all enjoy as new digital technology puts our untapped resources of talent and goodwill to use at last. Since we Americans were suburbanized and educated by the postwar boom, we've had a surfeit of intellect, energy, and time-what Shirky calls a cognitive surplus. But this abundance had little impact on the common good because television consumed the lion's share of it-and we consume TV passively, in isolation from one another. Now, for the first time, people are embracing new media that allow us to pool our efforts at vanishingly low cost. The results of this aggregated effort range from mind expanding-reference tools like Wikipedia-to lifesaving-such as Ushahidi.com, which has allowed Kenyans to sidestep government censorship and report on acts of violence in real time. Shirky argues persuasively that this cognitive surplus-rather than being some strange new departure from normal behavior-actually returns our society to forms of collaboration that were natural to us up through the early twentieth century. He also charts the vast effects that our cognitive surplus- aided by new technologies-will have on twenty-first-century society, and how we can best exploit those effects. Shirky envisions an era of lower creative quality on average but greater innovation, an increase in transparency in all areas of society, and a dramatic rise in productivity that will transform our civilization. The potential impact of cognitive surplus is enormous. As Shirky points out, Wikipedia was built out of roughly 1 percent of the man-hours that Americans spend watching TV every year. Wikipedia and other current products of cognitive surplus are only the iceberg's tip. Shirky shows how society and our daily lives will be improved dramatically as we learn to exploit our goodwill and free time like never before.

    Since its creation in 2010, Instagram’s fun and simple interface has captured our collective imagination, swiftly becoming a way of life. In No Filter: The Inside Story of Instagram, technology reporter Sarah Frier explains how Instagram’s founders married art and technology to overcome skeptics and to hook the public on visual storytelling. At first, Instagram initially attracted artisans, but then the platform exploded in popularity among the masses, creating an entire industry of digital influencers that’s now worth tens of billions of dollars. Eighteen months after Instagram’s launch and explosive growth, the founders—Kevin Systrom and Mike Krieger—made the gut-wrenching decision to sell the company to Facebook. For most companies, that would be the end of the story; but for Instagram, it was only the beginning. Instagram borrowed some lessons from Facebook and rejected others, until eventually its success stirred tension with Facebook’s CEO Mark Zuckerberg, just as Facebook became embroiled in a string of public crises. Frier unearths the details that led to the cofounders’ departure, bringing to light dramatic moments unknown to the public until now. At its heart, No Filter draws on unprecedented exclusive access—from the founders of Instagram, as well as employees, executives, and competitors; hedge fund billionaire Ray Dalio; Anna Wintour of Vogue; Kris Jenner of the Kardashian-Jenner empire; and a plethora of influencers, from fashionistas with millions of followers to owners of famous dogs worldwide—to show how Instagram has fundamentally changed the way we communicate, shop, eat, and travel. The book brings readers inside users’ strategies to craft their personal image and fame, explaining how the company’s product decisions have affected the structure of our society. From teenagers to the pope, No Filter tells the captivating story of how Instagram not only created a new industry but also changed our lives.
