In its first five years of existence, The Perl Journal (TPJ) became the voice of the Perl community. Every serious Perl programmer subscribed to it, and every notable Perl guru jumped at the opportunity to write for it. TPJ explained critical Perl topics and demonstrated Perl's utility for fields as diverse as astronomy, biology, economics, AI, and games. Back issues were hoarded, or swapped like trading cards. No longer in print format, The Perl Journal remains a proud and timeless achievement of Perl during one of its most exciting periods of development. Web, Graphics & Perl/Tk is the second volume of The Best of the Perl Journal, compiled and re-edited by the original editor and publisher of The Perl Journal, Jon Orwant. In this series, we've taken the very best (and still relevant) articles published in TPJ over its five years of publication and immortalized them into three volumes. The forty articles included in this volume are simply some of the best Perl articles ever written on the subjects of graphics, the Web, and Perl/Tk, by some of the best Perl authors and coders. Much of Perl's success is due to its capabilities for developing web sites; the Web section covers popular topics such as CGI programs, mod_perl, spidering, HTML parsing, security, and content management. The Graphics section is a grab bag of techniques, ranging from simple graph generation to ray tracing and real-time video digitizing. The Perl/Tk section shows you how to use the popular Perl/Tk toolkit for developing graphical applications that work on both Unix/Linux and Windows without a single change. Written by twenty-three of the most prominent and prolific members of the closely-knit Perl community, including Lincoln Stein, Mark-Jason Dominus, Alligator Descartes, and Dan Brian, this anthology does what no other book can, giving unique insight into the real-life applications and powerful techniques made possible by Perl.
For as long as there's been a Web, people have been trying to make it faster. The maturation of the Web has meant more users, more data, more bells and whistles, and consequently longer waits on the Web. Improved performance has become one of the most important factors in determining the usability of both the Web in general and of individual sites in particular. Web Performance Tuning is about getting the best performance from the Web. This book isn't just about tuning the web server software; it's also about getting optimal performance from a browser, tuning the hardware (on both the server and browser ends), and maximizing the capacity of the network itself. Web Performance Tuning hits the ground running, giving concrete advice for quick results--the "blunt instruments" for improving crippled performance right away. The book then takes a breath and pulls back to give a conceptual background of the principles of computing performance. The latter half of the book approaches each element of a web transaction--from client to network to server--to examine the weak links in the chain and how to strengthen them. Tips include: Using simultaneous downloads to locate bottlenecks Adjusting TCP for better web performance Reducing the impact of DNS Upgrading device drivers Using alternatives to CGI Locating the web server strategically Minimizing browser cache lookups Avoiding symbolic links for web content
Web Performance Tuning, 2nd Editionis about getting the best possible performance from the Web. This second edition has been significantly expanded, including new chapters on Web site architecture, security, and reliability. The book also includes many more examples and graphs of real-world performance problems and their solutions, and it has been updated for Java 2. Web Performance Tuningis for anyone who has waited too long for a Web page to display, or watched the servers they manage slow to a crawl.
This much expanded new edition explores web security risks and how to minimize them. Aimed at web users, administrators, and content providers, Web Security, Privacy and Commerce covers cryptography, SSL, the Public Key Infrastructure, digital signatures, digital certificates, privacy threats (cookies, log files, web logs, web bugs), hostile mobile code, and web publishing (intellectual property, P3P, digital payments, client-side digital signatures, code signing, PICS).
This PDF will show you how your small business or enterprise can publish its APIs (application programming interface) to a developer community just like the behemoths of the Internet--Google, Yahoo!, eBay, and Amazon. These giants already offer their APIs to other programmers and allow for add-on services and mash-ups to develop from them--but until recently, the capability for most enterprises to do the same was limited by a myriad of competing standards and a lack of easy-to-use tools to accomplish the task. Ruby on Rails levels the playing field for companies by simplifying the process of building web services and documenting APIs. Now with Rails, enterprise-quality tools are available for all developers. In this document, we'll look at how Ruby on Rails makes building web service clients and servers simple and fun. Along the way, we'll give working examples and code details so you can see just how everything works.
Ever since we first introduced the term Web 2.0, people have been asking, What TMs next? Assuming that Web 2.0 was meant to be a kind of software version number (rather than a statement about the second coming of the Web after the dotcom bust), we TMre constantly asked about Web 3.0. Is it the semantic web? The sentient web? Is it the social web? The mobile web? Is it some form of virtual reality? It is all of those, and more. The Web is no longer a collection of static pages of HTML that describe something in the world. Increasingly, the Web is the world "everything and everyone in the world casts an information shadow, an aura of data which, when captured and processed intelligently, offers extraordinary opportunity and mindbending implications. Web Squared is our way of exploring this phenomenon and giving it a name.
This essential guide for Web site designers offers clear, concise advice on creating well-designed and effective Web sites and pages. Focusing on the interface and graphic design principles that underlie the best Web site design, the book provides anyone involved with Web site design -- in corporations, government, nonprofit organizations, and academic institutions -- with expert guidance on issues ranging from planning and organizing goals to design strategies for a site to the elements of individual page design. Shifting away from the emphasis of many authors on HyperText Markup Language (HTML) and glitzy, gimmicky graphics, Patrick J. Lynch and Sarah Horton discuss classic principles of design, how these principles apply to Web design, and the issues and constraints of designing complex, multilayered sites. They address the practical concerns of bending and adapting HTML to the purposes of graphic page design. This book grew out of the widely used and highly praised Web site on site designcreated by,the Center for Advanced Instructional Media at Yale University (info. med. yale. ed/ cairn/manual/). At this site, readers will continue to find updated color illustrations and examples to complement and demonstrate points made in the book, as well as useful and current online references.
[Back Cover[ Tiny ID chips track every car, shirt, and razor blade purchased from corporate manufacturers. Governments and multinational corporations gather information on every citizen's race, family life, credit record, buying preferences, employment history, favorite TV shows, telephone conversations-and can surreptitiously peruse e-mails. Exoskeleton armor makes soldiers invincible, while mind-altering drugs make them incapable of remorse. In Welcome to the Machine, award-winning authors Derrick Jensen and George Draffan reveal the modern culture of the machine, where corporate might makes technology right, government money feeds the greed for mad science, and absolute surveillance leads to absolute control. Through meticulous research and fiercely personal narrative, Jensen and Draffan move beyond journalism and expose to question our civilization's very mode of existence. Welcome to the Machine challenges our submission to the institutions and technologies built to rob us of all that makes us human-our connection to the land, our kinship with one another, our place in the living world.
While there have been several histories of the personal computer, well-known technology writer John Markoff has created the first ever to spotlight the unique political and cultural forces that gave rise to this revolutionary technology. Focusing on the period of 1962 through 1975 in the San Francisco Bay Area, where a heady mix of tech industries, radicalism, and readily available drugs flourished, What the Dormouse Saidtells the story of the birth of the personal computer through the people, politics, and protest that defined its unique era. Based on interviews with all the major surviving players, Markoff vividly captures the lives and times of those who laid the groundwork for the PC revolution, introducing the reader to such colorful characters as Fred Moore, a teenage antiwar protester who went on to ignite the computer industry, and Cap'n Crunch, who wrote the first word processing software for the IBM PC (EZ Writer) in prison, became a millionaire, and ended up homeless. Both immensely informative and entertaining, What the Dormouse Said promises to appeal to all readers of technology, especially the bestselling The Soul of a New Machine.

We've all heard it: according to Hal Varian, statistics is the next sexy job. Five years ago, in What is Web 2.0, Tim O'Reilly said that "data is the next Intel Inside." But what does that statement mean? Why do we suddenly care about statistics and about data? This report examines the many sides of data science -- the technologies, the companies and the unique skill sets. The web is full of "data-driven apps." Almost any e-commerce application is a data-driven application. There's a database behind a web front end, and middleware that talks to a number of other databases and data services (credit card processing companies, banks, and so on). But merely using data isn't really what we mean by "data science." A data application acquires its value from the data itself, and creates more data as a result. It's not just an application with data; it's a data product. Data science enables the creation of data products.

Twenty five years ago, it didn't exist. Today, twenty million people worldwide are surfing the Net. Where Wizards Stay Up Late is the exciting story of the pioneers responsible for creating the most talked about, most influential, and most far-reaching communications breakthrough since the invention of the telephone. In the 1960's, when computers where regarded as mere giant calculators, J.C.R. Licklider at MIT saw them as the ultimate communications devices. With Defense Department funds, he and a band of visionary computer whizzes began work on a nationwide, interlocking network of computers. Taking readers behind the scenes, Where Wizards Stay Up Late captures the hard work, genius, and happy accidents of their daring, stunningly successful venture.
"A little more than twenty-five years ago, computer networks did not exist anywhere - except in the minds of a handful of computer scientists. In the late 1960s, the Defense Department's Advanced Research Projects Agency funded a project to create computer communication among its university-based researchers. The experiment was inspired by J. C. R. Licklider, a brilliant scientist from MIT. At a time when computers were generally regarded as nothing more than giant calculators, Licklider saw their potential as communications devices." "Where Wizards Stay Up Late is the story of the small group of researchers and engineers whose invention, daring in its day, became the foundation for the Internet. With ARPA's backing, Licklider and others began the quest for a way to connect computers across the country." "In 1969, ARPA awarded the contract to build the most integral piece of this network - a computerized switch called the Interface Message Processor, or IMP - to Bolt Beranek and Newman (BBN), a small Cambridge, Massachusetts, company. A half-dozen engineers at BBN, who called themselves the IMP Guys, knew it was possible to do what larger companies - including AT&T and IBM - had dismissed as impossible. But making computer networking possible required inventing new technologies. Working around the clock, the IMP Guys met a tight deadline, and the first IMP was installed at UCLA nine months after the contract award." "A nationwide network called the ARPANET grew from four initial sites. Protocols were developed, and along the way a series of accidental discoveries were made, not the least of which was e-mail. Almost immediately, e-mail became the most popular feature of the Net and the "@" sign became lodged in the iconography of our times. The ARPANET continued to grow, then merged with other computer networks to become today's Internet. In 1990, the ARPANET itself was shut down, fully merged by then with the Internet it had spawned.

Anyone who has done even a modest amount of browsing on the Internet has probably run across Wikipedia, the user-edited online encyclopedia that now dwarfs the online version of Encyclopedia Britannica. This is the prime example of what is called the new Web, or Web 2.0, where sites such as MySpace, YouTube, Flickr, and even the Human Genome Project allow mass collaboration from participants in the online community. These open systems can produce faster and more powerful results than the traditional closed proprietary systems that have been the norm for private industry and educational institutions. In just the last few years, traditional collaboration-in a meeting room, a conference call, even a convention center-has been superseded by collaborations on an astronomical scale. Today, encyclopedias, jetliners, operating systems, mutual funds, and many other items are being created by teams numbering in the thousands or even millions. While some leaders fear the heaving growth of these massive online communities, Wikinomics proves this fear is folly. Smart firms can harness collective capability and genius to spur innovation, growth, and success. A brilliant guide to one of the most profound changes of our time, Wikinomics challenges our most deeply-rooted assumptions about business and will prove indispensable to anyone who wants to understand competitiveness in the twenty-first century. Based on a $9 million research project led by bestselling author Don Tapscott, Wikinomics shows how masses of people can participate in the economy like never before. They are creating TV news stories, sequencing the human genome, remixing their favorite music, designing software, finding a cure for disease, editing school texts, inventing new cosmetics, or even building motorcycles. You'll read about: Rob McEwen, the Goldcorp, Inc. CEO who used open source tactics and an online competition to save his company and breathe new life into an old-fashioned industry. Flickr, Second Life, YouTube, and other thriving online communities that transcend social networking to pioneer a new form of collaborative production. Mature companies like Procter & Gamble that cultivate nimble, trust-based relationships with external collaborators to form vibrant business ecosystems. An important look into the future, Wikinomics will be your road map for doing business in the twenty-first century.
The most important change in Windows 2000 is the inclusion of Active Directory, a fully qualified directory service. It's such an important change that systems administrators are likely to find coming to grips with Active Directory to be one of their biggest headaches. But it doesn't have to be that way. Windows 2000 Active Directory puts you in charge of AD; it's an in-depth guide you will turn to whenever you need help, both before and after implementation.
Anyone who installs Windows 2000, creates a user, or adds a printer is a 2000 system administrator. This book covers all the important day-to-day administrative tasks, and includes the tools for performing each task in an alphabetical reference for easy look-up. What's the same and what's different between Windows 2000 and Windows NT? Has the GUI or the networking architecture changed, and if so, how? This book will help you bridge the gap between Windows NT and Windows 2000.
Windows administrators can accomplish many of their routine tasks much more quickly by using the command line (similar to the command line of DOS or Unix-based systems) than by going through the graphical user interface that most users associate with Windows. Windows 20000 Commands Pocket Reference documents the Windows command mode. It's designed for system administrators, but will also be valuable to many users. It includes most available Windows 2000 commands, as well as the most useful system administration command-line utilities from the Resource Kit. Weeded out of this book are Windows commands and command options that are obscure, obsolete, broken, unacceptably insecure, or frankly inadvisable, as well a few special-purpose classes of commands. Whenever several utilities perform essentially identical tasks, we include only the best of them. Commands are grouped according to their purpose and function; within a group, commands are arranged alphabetically. Options for each command are grouped by function and ordered by importance. The Windows 2000 Commands Pocket Reference complements Windows 2000 Administration in a Nutshell by conveying the kind of no-nonsense, boiled-down information typical of O'Reilly's highly successful companion Pocket Reference series. It's a valuable, concise reference to Windows 2000 commands and command-line utilities.
