Graphics programmers aren't the only ones who need to be proficient with graphics. Web and applications programmers know that a dull web page can be quickly transformed into one that's interesting and lively with the use of well-planned graphics. And fortunately, you don't need the skills of a fulltime graphics programmer to use graphics effectively. From access counters and log report graphs to scientific plots and on-the-fly animated GIFs, graphics scripting is within the grasp of most web programmers. Using open source software, like Perl, you have the power to dynamically generate graphics based on user input and activity, easily manipulate graphics content, and optimize graphics for compression and quality.Geared toward Perl users and webmasters, Perl Graphics Programming focuses on open-source scripting programs that manipulate graphics files for use on the Web. The book demystifies the manipulation of graphics formats for newcomers to the Web with a practical, resource-like approach. With this book you'll learn to:Generate dynamic web graphics with charts, tables, and buttonsAutomate graphics tasks (thumbnails and borders)Create dynamics web documents (PDF, Postscript)Produce rich Internet experiences with Flash and SVGYou'll begin with a tour of the most common web graphic file formats--PNG, JPEG, GIF, SWF, SVG, Postscript and PDF--then you'll explore the most powerful tools and Perl modules available for manipulating these graphics, such as GD, PerlMagick, and GIMP. Included in this part of the book is a thorough description of the Ming module for creating on-the-fly Flash files. Next, a "e;cookbook"e; section includes practical, all purpose recipes: GIF animation, generating images within a dynamic application, communicating between SWF front-end and Perl back-end, XSLT transformations, compression, and much more.Perl programmers naturally turn to Perl to tackle whatever challenge they have at hand, and graphics programming is no exception. Perl Graphics Programming provides all the tools you need to begin programming and designing graphics for the Web immediately. This book will change how you think about generating and manipulating graphics for the Web.
Ruby is an absolutely pure object-oriented scripting language written in C and designed with Perl and Python capabilities in mind. While its roots are in Japan, Ruby is slowly but surely gaining ground in the US. The goal of Yukihiro Matsumoto, creator of Ruby and author of this book, is to incorporate the strengths of languages like Perl, Python, Lisp and Smalltalk. Ruby is a genuine attempt to combine the best of everything in the scripting world. Since 1993, Ruby mailing lists have been established, Web pages have formed, and a community has grown around it. The language itself is very good at text processing and is notable for its broad object orientation. Ruby is portable and runs under GNU/Linux (and other Unices) as well as DOS, MS Windows and Mac.With Ruby in a Nutshell, Matsumoto offers a practical reference to the features of this new language including the command-line options, syntax, built-in variables, functions, and many commonly used classes and modules. This guide covers the current stable version of Ruby (1.6), yet is applicable to the development version 1.7 and the next planned stable version 1.8. You will find a thorough description of Ruby's language syntax, and a description of the core functionality built into the standard Ruby interpreter, which has more than 800 built-in methods in 42 classes and modules.Ruby finds its power through its built-in libraries, and this handy volume take you through the many useful libraries that come with the standard Ruby distribution--from network access via HTTP and CGI programming, to data persistence using the DBM library. This book concludes with coverage of the unique tools that come with Ruby, including the debugger, profiler, and irb (or interactive ruby.)Find out how Ruby combines the strengths of other languages, and why it has captured the interest of so many open source programmers. As part of the successful "e;in a nutshell"e; series of books from O'Reilly & Associates, Ruby in a Nutshell is for readers who want a single desktop reference for all their needs.

Since the first edition of this classic reference was published, World Wide Web use has exploded and e-commerce has become a daily part of business and personal life. As Web use has grown, so have the threats to our security and privacy--from credit card fraud to routine invasions of privacy by marketers to web site defacements to attacks that shut down popular web sites.Web Security, Privacy & Commerce goes behind the headlines, examines the major security risks facing us today, and explains how we can minimize them. It describes risks for Windows and Unix, Microsoft Internet Explorer and Netscape Navigator, and a wide range of current programs and products. In vast detail, the book covers:Web technology--The technological underpinnings of the modern Internet and the cryptographic foundations of e-commerce are discussed, along with SSL (the Secure Sockets Layer), the significance of the PKI (Public Key Infrastructure), and digital identification, including passwords, digital signatures, and biometrics.Web privacy and security for users--Learn the real risks to user privacy, including cookies, log files, identity theft, spam, web logs, and web bugs, and the most common risk, users' own willingness to provide e-commerce sites with personal information. Hostile mobile code in plug-ins, ActiveX controls, Java applets, and JavaScript, Flash, and Shockwave programs are also covered.Web server security--Administrators and service providers discover how to secure their systems and web services. Topics include CGI, PHP, SSL certificates, law enforcement issues, and more.Web content security--Zero in on web publishing issues for content providers, including intellectual property, copyright and trademark issues, P3P and privacy policies, digital payments, client-side digital signatures, code signing, pornography filtering and PICS, and other controls on web content.Nearly double the size of the first edition, this completely updated volume is destined to be the definitive reference on Web security risks and the techniques and technologies you can use to protect your privacy, your organization, your system, and your network.

The Web is slowly but surely changing from a model in which a human reader browses content on web pages to a model in which services and clients (not necessarily humans) exchange information. And because of this, author Silvia Puglisi explains, it makes more sense to build platforms instead of just products or applications. Platforms are like ecosystems interconnecting different applications, services, users, developers, and partners, and offer many benefits.In this book, you'll learn how to design and develop Representational State Transfer (REST) platforms in Rails. You'll begin with an introduction to Ruby on Rails, and then move quickly through new concepts. At the end of each chapter, you'll have learned something new about building and organically extending a multi-service platform spanning different devicesand will have had some fun in the process. By the end of the book you'll know how to build an architecture composed of different services accessing shared resources through a set of collaborating APIs and applications.Explore the basics of REST and HTTP, including REST architecture and the role of hypermediaGet to know Rails and Ruby on RailsLearn about API development and create an APITake a thorough look at REST, including Asynchronous REST and testing RESTful servicesWork with data streams as you map them onto an application UI and integrate external APIs in your applicationLearn about device-independent developmentUse data analytics to recognize important events, develop key metrics, and track themExplore various tools you can use to build your own data analytic platformLearn how to scale a Rails application successfullyExamine privacy and security issues and the implications of handling and collecting user data
