Author Steve Souders, in his job as Chief Performance Yahoo!, collected these best practices while optimizing some of the most-visited pages on the Web. Even sites that had already been highly optimized, such as Yahoo! Search and the Yahoo! Front Page, were able to benefit from these surprisingly simple performance guidelines.The rules in High Performance Web Sites explain how you can optimize the performance of the Ajax, CSS, JavaScript, Flash, and images that you've already built into your site -- adjustments that are critical for any rich web application. Other sources of information pay a lot of attention to tuning web servers, databases, and hardware, but the bulk of display time is taken up on the browser side and by the communication between server and browser. High Performance Web Sites covers every aspect of that process.Each performance rule is supported by specific examples, and code snippets are available on the book's companion web site. The rules include how to: Make Fewer HTTP RequestsUse a Content Delivery NetworkAdd an Expires HeaderGzip ComponentsPut Stylesheets at the TopPut Scripts at the BottomAvoid CSS ExpressionsMake JavaScript and CSS ExternalReduce DNS LookupsMinify JavaScriptAvoid RedirectsRemove Duplicates ScriptsConfigure ETagsMake Ajax CacheableIf you're building pages for high traffic destinations and want to optimize the experience of users visiting your site, this book is indispensable.If everyone would implement just 20% of Steve's guidelines, the Web would be adramatically better place. Between this book and Steve's YSlow extension, there's reallyno excuse for having a sluggish web site anymore.-Joe Hewitt, Developer of Firebug debugger and Mozilla's DOM InspectorSteve Souders has done a fantastic job of distilling a massive, semi-arcane art down to a set of concise, actionable, pragmatic engineering steps that will change the world of web performance.-Eric Lawrence, Developer of the Fiddler Web Debugger, Microsoft Corporation

    We want them to buy something, read more, or take action of some kind. Designing without understanding what makes people act the way they do is like exploring a new city without a map: results will be haphazard, confusing, and inefficient. This book combines real science and research with practical examples to deliver a guide every designer needs. With it you'll be able to design more intuitive and engaging work for print, websites, applications, and products that matches the way people think, work, and play.Learn to increase the effectiveness, conversion rates, and usability of your own design projects by finding the answers to questions such as: What grabs and holds attention on a page or screen?What makes memories stick?What is more important, peripheral or central vision?How can you predict the types of errors that people will make?What is the limit to someone's social circle?How do you motivate people to continue on to (the next step?What line length for text is best?Are some fonts better than others? These are just a few of the questions that the book answers in its deep-dive exploration of what makes people tick.

    These topics lie at the heart of many exciting areas of contemporary science and engineering - communication, signal processing, data mining, machine learning, pattern recognition, computational neuroscience, bioinformatics, and cryptography. This textbook introduces theory in tandem with applications. Information theory is taught alongside practical communication systems, such as arithmetic coding for data compression and sparse-graph codes for error-correction. A toolbox of inference techniques, including message-passing algorithms, Monte Carlo methods, and variational approximations, are developed alongside applications of these tools to clustering, convolutional codes, independent component analysis, and neural networks. The final part of the book describes the state of the art in error-correcting codes, including low-density parity-check codes, turbo codes, and digital fountain codes -- the twenty-first century standards for satellite communications, disk drives, and data broadcast. Richly illustrated, filled with worked examples and over 400 exercises, some with detailed solutions, David MacKay's groundbreaking book is ideal for self-learning and for undergraduate or graduate courses. Interludes on crosswords, evolution, and sex provide entertainment along the way. In sum, this is a textbook on information, communication, and coding for a new generation of students, and an unparalleled entry point into these subjects for professionals in areas as diverse as computational biology, financial engineering, and machine learning.

    There has been a marked increase in the adoption of PHP, most notably in the beginning to intermediate levels. PHP now boasts over 30% of the server side scripting market (Source: php.weblogs.com).The previous edition sold over 17,000 copies exclusively through Sitepoint.com alone. With the release of PHP 5, SitePoint have updated this bestseller to reflect best practice web development using PHP 5 and MySQL 4.The 3rd Edition includes more code examples and also a new bonus chapter on structured PHP Programming which introduces techniques for organizing real world PHP applications to avoid code duplication and ensure code is manageable and maintainable.

    They get frustrated losing their scroll position; they get annoyed waiting for refresh; they struggle to reorient themselves on every new page. And the list goes on. With asynchronous JavaScript and XML, known as "Ajax," you can give them a better experience. Once users have experienced an Ajax interface, they hate to go back. Ajax is new way of thinking that can result in a flowing and intuitive interaction with the user.Ajax in Action helps you implement that thinking--it explains how to distribute the application between the client and the server (hint: use a "nested MVC" design) while retaining the integrity of the system. You will learn how to ensure your app is flexible and maintainable, and how good, structured design can help avoid problems like browser incompatibilities. Along the way it helps you unlearn many old coding habits. Above all, it opens your mind to the many advantages gained by placing much of the processing in the browser. If you are a web developer who has prior experience with web technologies, this book is for you. Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book.
