Squid is the most popular Web caching software in use today, and it works on a variety of platforms including Linux, FreeBSD, and Windows. Squid improves network performance by reducing the amount of bandwidth used when surfing the Web. It makes web pages load faster and can even reduce the load on your web server. By caching and reusing popular web content, Squid allows you to get by with smaller network connections. It also protects the host on your internal network by acting as a firewall and proxying your internal web traffic. You can use Squid to collect statistics about the traffic on your network, prevent users from visiting inappropriate web sites at work or school, ensure that only authorized users can surf the Internet, and enhance your privacy by filtering sensitive information from web requests. Companies, schools, libraries, and organizations that use web-caching proxies can look forward to a multitude of benefits.Written by Duane Wessels, the creator of Squid, Squid: The Definitive Guide will help you configure and tune Squid for your particular situation. Newcomers to Squid will learn how to download, compile, and install code. Seasoned users of Squid will be interested in the later chapters, which tackle advanced topics such as high-performance storage options, rewriting requests, HTTP server acceleration, monitoring, debugging, and troubleshooting Squid.Topics covered include: Compiling and installing Squid Running Squid Using Squid's sophisticated access controls Tuning disk storage for optimal performance Configuring your operating system for HTTP interception Forwarding Requests to other web caches Using redirectors to rewrite user requests Monitoring Squid with the cache manager and SNMP Using Squid to accelerate and protect HTTP servers Managing bandwidth consumption with Delay Pools

The Australasian region is home to the greatest diversity of cephalopods — squid, cuttlefish, octopuses — in the world. Yet, we know very little about these fascinating marine animals. This book provides insights into the biology and behaviour of more than 60 species. From the Giant Squid to the deadly Blue-ringed Octopus, the secret lives of cephalopods are revealed in a highly readable form with outstanding colour images and informative text. For each species there is a distribution map and identification notes which summarise the main features to look for. While the book focuses on species found in relatively shallow coastal waters, a few of the more bizarre deeper-water species are included. Naturalists, divers, reef-walkers and anglers will find the book authoritative, yet very easy to use. A comprehensive section illustrating cuttlebones will enable beachcombers to identify most of the species they are likely to encounter.

The predecessor to this book was A Guide to the Laboratory Use of the Squid Loligo pealei published by the Marine Biological Laboratory, Woods Hole, Massachusetts in 1974. The revision of this long out of date guide, with the approval of the Marine Biological Laboratory, is an attempt to introduce students and researchers to the cephalopods and particularly the squid as an object of biological research. Therefore, we have decided to expand on its original theme, which was to present important practical aspects for using the squid as experimental animals. There are twenty two chapters instead of the original eight. The material in the original eight chapters has been completely revised. Since more than one method can be used for accomplishing a given task, some duplication of methods was considered desirable in the various chapters. Thus, the methodology can be chosen which is best suited for each reader's requirements. Each subject also contains a mini-review which can serve as an introduction to the various topics. Thus, the volume is not just a laboratory manual, but can also be used as an introduction to squid biology. The book is intended for laboratory technicians, advanced undergraduate students, graduate students, researchers, and all others who want to learn the purpose, methods, and techniques of using squid as experimental animals. This is the reason why the name has been changed to its present title. Preceding the chapters is a list of many of the abbreviations, prefixes, and suffixes used in this volume.

When James Murray compiled the OED in the 19th century, he used a small army of volunteers--and thousands upon thousands of paper slips--to track down the English language. Today, linguists use massive computer power--including the world's largest language databank, the Oxford Corpus, which contains more than two billion words--to determine for the first time definitively how the English language is used. From evidence contained in the gargantuan Oxford Corpus, Jeremy Butterfield here uncovers a wealth of fascinating facts about the English language. Where does our vocabulary come from? How do word meanings change? How is our language really being used? This entertaining book has the up-to-date and authoritative answers to all the key questions about our language. Butterfield takes a thorough look at the English language and exposes its peculiarities and penchants, its development and difficulties, revealing exactly how it operates. We learn, for instance, that we use language in chunks of words--as one linguist put it, "we know words by the company that they keep." For instance, the word quintessentially is joined half the time with a nationality--something is "quintessentially American" or "quintessentially British." Using such observations, Butterfield explains how dictionary makers decide which words to include, how they find definitions, and how the Corpus influences the process. Covering all areas of English, from spelling and idioms to the future of English, and with entertaining examples and useful charts throughout, this compelling and lively book will delight word lovers everywhere.

A treasure trove of scientific fact and visual explanation offers a comprehensive review of these fascinating and mysterious marine invertebrates. There are over 700 species of cephalopod, and their existence proofs that intelligence develops in very different ways–it is not by accident that these creatures are favourite models for science fiction and fantasy. While whale brains look somewhat similar to ours, cephalopods carry a large percentage of their brains in their arms. They are capable of learning, and of retaining information. They have eyes and other senses rivalling those of humans, they change texture and body shape, and they change colour faster than a chameleon. From the lone, inky hunting of the octopus, to the social squid, and the unusually large brained cuttlefish, Octopus, Squid, & Cuttlefish reveals the evolution, anatomy, life history, behaviours, and relationships of these spellbinding creatures.

Behind every web transaction lies the Hypertext Transfer Protocol (HTTP) --- the language of web browsers and servers, of portals and search engines, of e-commerce and web services. Understanding HTTP is essential for practically all web-based programming, design, analysis, and administration.While the basics of HTTP are elegantly simple, the protocol's advanced features are notoriously confusing, because they knit together complex technologies and terminology from many disciplines. This book clearly explains HTTP and these interrelated core technologies, in twenty-one logically organized chapters, backed up by hundreds of detailed illustrations and examples, and convenient reference appendices. HTTP: The Definitive Guide explains everything people need to use HTTP efficiently -- including the "black arts" and "tricks of the trade" -- in a concise and readable manner.In addition to explaining the basic HTTP features, syntax and guidelines, this book clarifies related, but often misunderstood topics, such as: TCP connection management, web proxy and cache architectures, web robots and robots.txt files, Basic and Digest authentication, secure HTTP transactions, entity body processing, internationalized content, and traffic redirection.Many technical professionals will benefit from this book. Internet architects and developers who need to design and develop software, IT professionals who need to understand Internet architectural components and interactions, multimedia designers who need to publish and host multimedia, performance engineers who need to optimize web performance, technical marketing professionals who need a clear picture of core web architectures and protocols, as well as untold numbers of students and hobbyists will all benefit from the knowledge packed in this volume.There are many books that explain how to use the Web, but this is the one that explains how the Web works. Written by experts with years of design and implementation experience, this book is the definitive technical bible that describes the "why" and the "how" of HTTP and web core technologies. HTTP: The Definitive Guide is an essential reference that no technically-inclined member of the Internet community should be without.

“Wolf restores our awe of the human brain—its adaptability, its creativity, and its ability to connect with other minds through a procession of silly squiggles.” — San Francisco Chronicle How do people learn to read and write—and how has the development of these skills transformed the brain and the world itself ? Neuropsychologist and child development expert Maryann Wolf answers these questions in this ambitious and provocative book that chronicles the remarkable journey of written language not only throughout our evolution but also over the course of a single child’s life, showing why a growing percentage have difficulty mastering these abilities. With fascinating down-to-earth examples and lively personal anecdotes, Wolf asserts that the brain that examined the tiny clay tablets of the Sumerians is a very different brain from the one that is immersed in today’s technology-driven literacy, in which visual images on the screen are paving the way for a reduced need for written language—with potentially profound consequences for our future.
