Photography is a complex craft. Some excel at the technical side of image-making, focusing perfectly on the subject, releasing the shutter at just the right moment and making exposures with the precise amount of light. Others are artists and storytellers, capturing a fleeting moment in time which inspires a viewer to gaze upon an image and ponder its meaning. The best photographers are masters of both.

In this highly visual, informative new book, Angela Faris Belt discusses the four crucial elements of photography that are essential for successful technical and conceptual image-making:

the photographic frame and its borders
quality of focus as determined by the aperture or lens
shutter speeds and their effects in relation to time and motion
the physical media used to create the aggregate image

Step-by-step guidance including informative screen shots, traditional darkroom and Photoshop techniques, suggested exercises, and before and after images help both film and digital photographers improve their skills, learn new techniques, and better understand their craft. More than 300 stunning, full color images and portfolios featuring the work of over 40 prestigious artists provide visual inspiration as well as a gorgeous collection of artwork for photography enthusiasts.

Portable, powerful, and a breeze to use, Python is ideal for both standalone programs and scripting applications. With this hands-on book, you can master the fundamentals of the core Python language quickly and efficiently, whether you're new to programming or just new to Python. Once you finish, you will know enough about the language to use it in any application domain you choose.

Learning Python is based on material from author Mark Lutz's popular training courses, which he's taught over the past decade. Each chapter is a self-contained lesson that helps you thoroughly understand a key component of Python before you continue. Along with plenty of annotated examples, illustrations, and chapter summaries, every chapter also contains Brain Builder, a unique section with practical exercises and review quizzes that let you practice new skills and test your understanding as you go.

This book covers:

• Types and Operations -- Python's major built-in object types in depth: numbers, lists, dictionaries, and more
• Statements and Syntax -- the code you type to create and process objects in Python, along with Python's general syntax model
• Functions -- Python's basic procedural tool for structuring and reusing code
• Modules -- packages of statements, functions, and other tools organized into larger components
• Classes and OOP -- Python's optional object-oriented programming tool for structuring code for customization and reuse
• Exceptions and Tools -- exception handling model and statements, plus a look at development tools for writing larger programs

Learning Python gives you a deep and complete understanding of the language that will help you comprehend any application-level examples of Python that you later encounter. If you're ready to discover what Google and YouTube see in Python, this book is the best way to get started.

Smart web developers will tell you that the sooner you detect your code mistakes, the quicker you can fix them, and the less the project will cost in the long run. Well, the most efficient way to detect your mistakes in PHP is with PHPUnit, an open source framework that automates unit testing by running a battery of tests as you go. The benefits of PHPUnit are significant:

• a reduction in the effort required to frequently test code
• fewer overall defects
• added confidence in your code
• improved relations with your open source teammates

The only problem with this popular testing tool was its lack of documentation-until now, that is. For this, O'Reilly went right to the source, as Sebastian Bergmann, the author of PHPUnit Pocket Guide, also happens to be PHPUnit's creator. This little book brings together hard-to-remember information, syntax, and rules for working with PHPUnit. It also delivers the insight and sage advice that can only come from the technology's creator. Coverage of testing under agile methodologies and Extreme Programming (XP) is also included.

The latest in O'Reilly's series of handy Pocket Guides, this quick-reference book puts all the answers are right at your fingertips. It's an invaluable companion for anyone interested in testing the PHP code they write for web applications.

Like any other software system, Web sites gradually accumulate “cruft” over time. They slow down. Links break. Security and compatibility problems mysteriously appear. New features don’t integrate seamlessly. Things just don’t work as well. In an ideal world, you’d rebuild from scratch. But you can’t: there’s no time or money for that. Fortunately, there’s a solution: You can refactor your Web code using easy, proven techniques, tools, and recipes adapted from the world of software development.

In Refactoring HTML, Elliotte Rusty Harold explains how to use refactoring to improve virtually any Web site or application. Writing for programmers and non-programmers alike, Harold shows how to refactor for better reliability, performance, usability, security, accessibility, compatibility, and even search engine placement. Step by step, he shows how to migrate obsolete code to today’s stable Web standards, including XHTML, CSS, and REST—and eliminate chronic problems like presentation-based markup, stateful applications, and “tag soup.”

The book’s extensive catalog of detailed refactorings and practical “recipes for success” are organized to help you find specific solutions fast, and get maximum benefit for minimum effort. Using this book, you can quickly improve site performance now—and make your site far easier to enhance, maintain, and scale for years to come.

FreeBSD and OpenBSD are increasingly gaining traction in educational institutions, non-profits, and corporations worldwide because they provide significant security advantages over Linux. Although a lot can be said for the robustness, clean organization, and stability of the BSD operating systems, security is one of the main reasons system administrators use these two platforms.

There are plenty of books to help you get a FreeBSD or OpenBSD system off the ground, and all of them touch on security to some extent, usually dedicating a chapter to the subject. But, as security is commonly named as the key concern for today's system administrators, a single chapter on the subject can't provide the depth of information you need to keep your systems secure.

FreeBSD and OpenBSD are rife with security "building blocks" that you can put to use, and Mastering FreeBSD and OpenBSD Security shows you how. Both operating systems have kernel options and filesystem features that go well beyond traditional Unix permissions and controls. This power and flexibility is valuable, but the colossal range of possibilities need to be tackled one step at a time. This book walks you through the installation of a hardened operating system, the installation and configuration of critical services, and ongoing maintenance of your FreeBSD and OpenBSD systems.

Using an application-specific approach that builds on your existing knowledge, the book provides sound technical information on FreeBSD and Open-BSD security with plenty of real-world examples to help you configure and deploy a secure system. By imparting a solid technical foundation as well as practical know-how, it enables administrators to push their server's security to the next level. Even administrators in other environments--like Linux and Solaris--can find useful paradigms to emulate.

Written by security professionals with two decades of operating system experience, Mastering FreeBSD and OpenBSD Security features broad and deep explanations of how how to secure your most critical systems. Where other books on BSD systems help you achieve functionality, this book will help you more thoroughly secure your deployments.

A step-by-step guide to building PHP web sites and applications using the Smarty templating engine
- Bring the benefits of Smarty to your PHP programming
-Give your designers the power to modify content and layout without PHP programming
-Produce code that is easier to debug, maintain, and modify
-Useful for both Smarty developers and users

Smarty is a templating engine for PHP. Designers who are used to working with HTML files can work with Smarty templates, which are HTML files with simple tags while programmers work with the underlying PHP code. The Smarty engine brings the code and templates together. The result of all this is that designers can concentrate on designing, programmers can concentrate on programming, and they don't need to get in each others way so much. Even if you are developing a site on your own, Smarty is a powerful way to make your code clearer to you and others, as well as easier to debug and modify later.

This book is a comprehensive guide to all aspects of using Smarty. It will help you to:
-Install and configure Smarty on your Web server
- Understand how Smarty affects your web site architecture, and build site foundations that make the most of what Smarty offers
- Designers will learn to work with templates that contain variables and logic, to modify layouts or content of Smarty web sites
- See how Smarty caching can improve the performance of your sites
- Develop custom Smarty functions and plug-ins to incorporate into your templates

Using a step-by-step approach based on realistic examples, the expert authors show you how to use Smarty in your own PHP development. The book is ideal for PHP developers who are new to Smarty, and for web designers who are working with PHP developers who are using Smarty.
