    It also works beautifully with other open source tools, such as the MySQL database and the Apache web server. However, as more web sites are developed in PHP, they become targets for malicious attackers, and developers need to prepare for the attacks.Security is an issue that demands attention, given the growing frequency of attacks on web sites. Essential PHP Security explains the most common types of attacks and how to write code that isn't susceptible to them. By examining specific attacks and the techniques used to protect against them, you will have a deeper understanding and appreciation of the safeguards you are about to learn in this book.In the much-needed (and highly-requested) Essential PHP Security, each chapter covers an aspect of a web application (such as form processing, database programming, session management, and authentication). Chapters describe potential attacks with examples and then explain techniques to help you prevent those attacks.Topics covered include:Preventing cross-site scripting (XSS) vulnerabilitiesProtecting against SQL injection attacksComplicating session hijacking attemptsYou are in good hands with author Chris Shiflett, an internationally-recognized expert in the field of PHP security. Shiflett is also the founder and President of Brain Bulb, a PHP consultancy that offers a variety of services to clients around the world.

    With this guide, pioneering Go programmer Mark Summerfield shows how to write code that takes full advantage of Go's breakthrough features and idioms. Both a tutorial and a language reference, "Programming in Go" brings together all the knowledge you need to evaluate Go, think in Go, and write high-performance software with Go. Summerfield presents multiple idiom comparisons showing exactly how Go improves upon older languages, calling special attention to Go's key innovations. Along the way, he explains everything from the absolute basics through Go's lock-free channel-based concurrency and its flexible and unusual duck-typing type-safe approach to object-orientation. Throughout, Summerfield's approach is thoroughly practical. Each chapter offers multiple live code examples designed to encourage experimentation and help you quickly develop mastery. Wherever possible, complete programs and packages are presented to provide realistic use cases, as well as exercises. Coverage includes:-- Quickly getting and installing Go, and building and running Go programs -- Exploring Go's syntax, features, and extensive standard library -- Programming Boolean values, expressions, and numeric types -- Creating, comparing, indexing, slicing, and formatting strings -- Understanding Go's highly efficient built-in collection types: slices and maps -- Using Go as a procedural programming language -- Discovering Go's unusual and flexible approach to object orientation -- Mastering Go's unique, simple, and natural approach to fine-grained concurrency -- Reading and writing binary, text, JSON, and XML files -- Importing and using standard library packages, custom packages, and third-party packages -- Creating, documenting, unit testing, and benchmarking custom packages

    How does the spectacle of the sufferings of others (via television or newspapers) affect us? Are viewers inured--or incited--to violence by the depiction of cruelty? In Regarding the Pain of Others, Sontag takes a fresh look at the representation of atrocity--from Goya's The Disasters of War to photographs of the American Civil War, lynchings of blacks in the South, and the Nazi death camps, to contemporary horrific images of Bosnia, Sierra Leone, Rwanda, Israel and Palestine, and New York City on September 11, 2001. In Regarding the Pain of Others Susan Sontag once again changes the way we think about the uses and meanings of images in our world, and offers an important reflection about how war itself is waged (and understood) in our time.Features an analysis of our numbed response to images of horror. This title alters our thinking about the uses and meanings of images, and about the nature of war, the limits of sympathy, and the obligations of conscience.

    This book uniquely concentrates on creative techniques for the digital SLR photographer. Photography with Digital SLR and "SLR-like" cameras isn't exactly like conventional film SLR photography; nor is it exactly like digital photography with non-SLR cameras. DSLRs have special advantages, special features, and special problems that need to be addressed and embraced. In addition, users of these cameras tend to expect more from their photography and crave the kind of information that will let them wring every ounce of creativity out of their equipment. Anyone who has a Windows PC or Macintosh and a digital SLR camera will find advanced techniques in this book. Readers will cover various aspects of DSLRs including: why DSLRs work best for creative posing for group and individual portraits, using DSLRs to capture close-up scenes on the desktop using the digital camera's special capabilities, how to get great travel photos with a DSLR, and how to archive them when far from a computer.

     We are living in a time of deep divisions. Americans are sorting themselves along racial, religious, and cultural lines, leading to a level of polarization that the country hasn't seen since the Civil War. Pundits and politicians are calling for us to come together, to find common purpose. But how, exactly, can this be done?In Palaces for the People, Eric Klinenberg suggests a way forward. He believes that the future of democratic societies rests not simply on shared values but on shared spaces: the libraries, childcare centers, bookstores, churches, synagogues, and parks where crucial, sometimes life-saving connections, are formed. These are places where people gather and linger, making friends across group lines and strengthening the entire community. Klinenberg calls this the "social infrastructure" When it is strong, neighborhoods flourish; when it is neglected, as it has been in recent years, families and individuals must fend for themselves.Klinenberg takes us around the globe--from a floating school in Bangladesh to an arts incubator in Chicago, from a soccer pitch in Queens to an evangelical church in Houston--to show how social infrastructure is helping to solve some of our most pressing challenges: isolation, crime, education, addiction, political polarization, and even climate change.Richly reported, elegantly written, and ultimately uplifting, Palaces for the People urges us to acknowledge the crucial role these spaces play in civic life. Our social infrastructure could be the key to bridging our seemingly unbridgeable divides--and safeguarding democracy.

    What one does with this desire is what we call gender." So begins Andrea Long Chu's investigation into gender and desire, females and bodies, radical dreams and philosophical pessimism, and feminism as a form of political suicide. Feminism, Chu argues, is an untenable claim, and "when you make an untenable claim, your desire is showing, like a shy tattoo peeking out from a sleeve." Written in a series of linked theses, this is a provocative and searching text from our most exciting new public intellectual, a self described "sad trans girl in Brooklyn." Chu wears her heart on her sleeve with wit, style, and a manic searching grace.

    Who are these people, what motivates them, and why should you care?Consider these facts: Everything around us is turning into computers. Your typewriter is gone, replaced by a computer. Your phone has turned into a computer. So has your camera. Soon your TV will. Your car was not only designed on computers, but has more processing power in it than a room-sized mainframe did in 1970. Letters, encyclopedias, newspapers, and even your local store are being replaced by the Internet.Hackers & Painters: Big Ideas from the Computer Age, by Paul Graham, explains this world and the motivations of the people who occupy it. In clear, thoughtful prose that draws on illuminating historical examples, Graham takes readers on an unflinching exploration into what he calls “an intellectual Wild West.”The ideas discussed in this book will have a powerful and lasting impact on how we think, how we work, how we develop technology, and how we live. Topics include the importance of beauty in software design, how to make wealth, heresy and free speech, the programming language renaissance, the open-source movement, digital design, internet startups, and more.

    The fantastic journey began in 1977, before the first episode of Cosmos aired. The mission was planned as a grand tour beyond the moon; beyond Mars, Jupiter, and Saturn; and maybe even into interstellar space. The fact that it actually happened makes this humanity's greatest space mission.In The Interstellar Age, award-winning planetary scientist Jim Bell reveals what drove and continues to drive the members of this extraordinary team, including Ed Stone, Voyager's chief scientist and the one-time head of NASA's Jet Propulsion Lab; Charley Kohlhase, an orbital dynamics engineer who helped to design many of the critical slingshot maneuvers around planets that enabled the Voyagers to travel so far; and the geologist whose Earth-bound experience would prove of little help in interpreting the strange new landscapes revealed in the Voyagers' astoundingly clear images of moons and planets.Speeding through space at a mind-bending eleven miles a second, Voyager 1 is now beyond our solar system's planets. It carries with it artifacts of human civilization. By the time Voyager passes its first star in about 40,000 years, the gold record on the spacecraft, containing various music and images including Chuck Berry's "Johnny B. Goode," will still be playable.
