    Crammed with information about host security, it saved many a UNIX system administrator and user from disaster.This second edition is a complete rewrite of the original book. It's packed with twice the pages and offers even more practical information for UNIX users and administrators. It covers features of many types of UNIX systems, including SunOS, Solaris, BSDI, AIX, HP-UX, Digital UNIX, Linux, and others. The first edition was practical, entertaining, and full of useful scripts, tips, and warnings. This edition is all those things -- and more.If you are a UNIX system administrator or user in this security-conscious age, you need this book. It's a practical guide that spells out, in readable and entertaining language, the threats, the system vulnerabilities, and the countermeasures you can adopt to protect your UNIX system, network, and Internet connection. It's complete -- covering both host and network security -- and doesn't require that you be a programmer or a UNIX guru to use it.Practical UNIX & Internet Security describes the issues, approaches, and methods for implementing security measures. It covers UNIX basics, the details of security, the ways that intruders can get into your system, and the ways you can detect them, clean up after them, and even prosecute them if they do get in. Filled with practical scripts, tricks, and warnings, Practical UNIX & Internet Security tells you everything you need to know to make your UNIX system as secure as it possible can be.Contents include:Part I: Computer Security Basics.

    You need to stay current on the relevant Web specifications, like HTML, CSS, DOM, and ECMAScript. You also need to know how the latest Web browsers from Netscape and Microsoft actually implement these standards, since browser implementations of the standards are less than perfect. Right now, you're forced to keep multiple reference books open on your desk (or multiple browser windows open on your screen), just to develop a simple dynamic Web page that works properly under both Navigator and Internet Explorer.Dynamic HTML: The Definitive Reference changes all that. This book is an indispensable compendium for Web content developers. It contains everything you need to create functional cross-platform Web applications, including:A complete reference for all of the HTML tags, CSS style attributes, browser document objects, and JavaScript objects supported by the various standards and the latest versions of Navigator and Internet Explorer. Browser compatibility is emphasized throughout; the reference pages clearly indicate browser support for every entity. Handy cross-reference indexes that make it easy to find interrelated HTML tags, style attributes, and document objects. An advanced introduction to creating dynamic Web content that addresses the cross-platform compromises inherent in Web page design today. If you have some experience with basic Web page creation, but are new to the world of dynamic content, Dynamic HTML: The Definitive Reference will jump-start your development efforts. If you are an experienced Web programmer, you'll find the browser-compatibility information invaluable. This book is the only DHTML reference that a Web developer needs.Dynamic HTML: The Definitive Reference is designed to work in conjunction with HTML: The Definitive Guide and JavaScript: The Definitive Guide. HTML: The Definitive Guide teaches you about every element of HTML in detail, with explanations of how each element works and how it interacts with other elements, as well as numerous examples. JavaScript: The Definitive Guide provides a thorough description of the JavaScript language, complete with sophisticated examples that show you how to handle common Web application tasks. Together, these three books provide a complete library for Web content developers.

    This book teaches basic Artificial Intelligence algorithms such as dimensionality, distance metrics, clustering, error calculation, hill climbing, Nelder Mead, and linear regression. These are not just foundational algorithms for the rest of the series, but are very useful in their own right. The book explains all algorithms using actual numeric calculations that you can perform yourself. Artificial Intelligence for Humans is a book series meant to teach AI to those without an extensive mathematical background. The reader needs only a knowledge of basic college algebra or computer programming—anything more complicated than that is thoroughly explained. Every chapter also includes a programming example. Examples are currently provided in Java, C#, R, Python and C. Other languages planned.

    1 Welcome to ggplot2 ggplot2 is an R package for producing statistical, or data, graphics, but it is unlike most other graphics packages because it has a deep underlying grammar. This grammar, based on the Grammar of Graphics (Wilkinson, 2005), is composed of a set of independent components that can be composed in many di?erent ways. This makesggplot2 very powerful, because you are not limited to a set of pre-speci?ed graphics, but you can create new graphics that are precisely tailored for your problem. This may sound overwhelming, but because there is a simple set of core principles and very few special cases, ggplot2 is also easy to learn (although it may take a little time to forget your preconceptions from other graphics tools). Practically, ggplot2 provides beautiful, hassle-free plots, that take care of ?ddly details like drawing legends. The plots can be built up iteratively and edited later. A carefully chosen set of defaults means that most of the time you can produce a publication-quality graphic in seconds, but if you do have special formatting requirements, a comprehensive theming system makes it easy to do what you want. Instead of spending time making your graph look pretty, you can focus on creating a graph that best reveals the messages in your data
