So, why does conventional wisdom insist that software engineers focus primarily on the design and development of large-scale computing systems?In this collection of essays and articles, key members of Google's Site Reliability Team explain how and why their commitment to the entire lifecycle has enabled the company to successfully build, deploy, monitor, and maintain some of the largest software systems in the world. You'll learn the principles and practices that enable Google engineers to make systems more scalable, reliable, and efficient--lessons directly applicable to your organization.This book is divided into four sections: Introduction--Learn what site reliability engineering is and why it differs from conventional IT industry practicesPrinciples--Examine the patterns, behaviors, and areas of concern that influence the work of a site reliability engineer (SRE)Practices--Understand the theory and practice of an SRE's day-to-day work: building and operating large distributed computing systemsManagement--Explore Google's best practices for training, communication, and meetings that your organization can use

    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.

    Anyone with a modest knowledge of HTML and web site management can learn to create dynamic content through the PHP programming language and the MySQL database. This book gives you the background and tools to do the job safely and reliably.Web Database Applications with PHP and MySQL, Second Edition thoroughly reflects the needs of real-world applications. It goes into detail on such practical issues as validating input (do you know what a proper credit card number looks like?), logging in users, and using templates to give your dynamic web pages a standard look.But this book goes even further. It shows how JavaScript and PHP can be used in tandem to make a user's experience faster and more pleasant. It shows the correct way to handle errors in user input so that a site looks professional. It introduces the vast collection of powerful tools available in the PEAR repository and shows how to use some of the most popular tools.Even while it serves as an introduction to new programmers, the book does not omit critical tasks that web sites require. For instance, every site that allows updates must handle the possibility of multiple users accessing data at the same time. This book explains how to solve the problem in detail with locking.Through a sophisticated sample application--Hugh and Dave's Wine Store--all the important techniques of dynamic content are introduced. Good design is emphasized, such as dividing logic from presentation. The book introduces PHP 5 and MySQL 4.1 features, while providing techniques that can be used on older versions of the software that are still in widespread use.This new edition has been redesigned around the rich offerings of PEAR. Several of these, including the Template package and the database-independent query API, are fully integrated into examples and thoroughly described in the text. Topics include:Installation and configuration of Apache, MySQL, and PHP on Unix®, Windows®, and Mac OS® X systems Introductions to PHP, SQL, and MySQL administration Session management, including the use of a custom database for improved efficiency User input validation, security, and authentication The PEAR repository, plus details on the use of PEAR DB and Template classes Production of PDF reports

    As an important contributor to the online documentation for MySQL, Paul uses his day-to-day experience answering questions users post on the MySQL mailing list to pinpoint the problems most users and administrators encounter. The principal MySQL developer, Monty Widenius, along with a network of his fellow developers, reviewed the manuscript, providing Paul with the kind of insight no one else could supply. Instead of merely giving you a general overview of MySQL, Paul teaches you how to make the most of its capabilities. Through two sample databases that run throughout the book, he gives you solutions to problems you'll likely face. He helps you integrate MySQL efficiently with third-party tools, such as PHP and Perl, enabling you to generate dynamic Web pages through database queries. He also teaches you to write programs that access MySQL databases.

    I realize that sounds more like a line out of an existential movie — maybe Waiting for Godot or a screenplay by Sartre — than a statement about HTML5. But it’s really the truth: most of the people using HTML5 are treating it as HTML4+, or even worse, HTML4 (and some stuff they don’t use). The result? A real delay in the paradigm shift that HTML5 is almost certain to bring. It’s certainly not time to look away, because by the time you look back, you may have missed something really important: a subtle but important transition centered around HTML5.

    Since the last edition of this book appeared five years ago, there has been a major climate change with regard to web standards. Designers are no longer using (X)HTML as a design tool, but as a means of defining the meaning and structure of content. Cascading Style Sheets are no longer just something interesting to tinker with, but rather a reliable method for handling all matters of presentation, from fonts and colors to the layout of the entire page. In fact, following the standards is now a mandate of professional web design.Our popular reference, Web Design in a Nutshell, is one of the first books to capture this new web landscape with an edition that's been completely rewritten and expanded to reflect the state of the art. In addition to being an authoritative reference for (X)HTML and Cascading Style Sheets, this book also provides an overview of the unique requirements of designing for the Web and gets to the nitty-gritty of JavaScript and DOM Scripting, web graphics optimization, and multimedia production. It is an indispensable tool for web designers and developers of all levels.The third edition covers these contemporary web design topics:Structural layer: HTML 4.01 and XHTML 1.0 (9 chapters), including an alphabetical reference of all elements, attributes and character entities Presentation layer: Ten all-new chapters on Cascading Style Sheets, Level 2.1, including an alphabetical reference of all properties and values. Behavior layer: JavaScript and scripting with the Document Object Model (DOM) Web environment: New web standards, browsers, display devices, accessibility, and internationalization Web graphics optimization: Producing lean and mean GIF, JPEG, PNG, and animated GIFs Multimedia: Web audio, video, Flash, and PDFOrganized so that readers can find answers quickly, Web Design in a Nutshell, Third Edition helps experienced designers come up to speed quickly on standards-based web design, and serves as a quick reference for those already familiar with the new standards and technology. There are many books for web designers, but none that address such a wide variety of topics. Find out why nearly half a million buyers have made this the most popular web design book available.
