qmail has quietly become one of the most widely used applications on the Internet today. It's powerful enough to handle mail for systems with millions of users--Like Yahoo! Mail and Hotmail, while remaining compact and manageable enough for the smallest Unix- and Linux-based PC systems. Its component design makes it easy to extend and customize while keeping its key functions secure, so it's no wonder that adoption of qmail continues at a rapid pace.

The downside? Apparently none. Except that qmail's unique design can be disorienting to those familiar with other popular MTAs (Mail Transfer Agents). If you're coming from sendmail, for instance, you might have trouble recasting your problems and solutions in qmail terms. qmail first helps you establish a "qmail frame of mind," then explores the installation, configuration, administration, and extension of this powerful MTA. Whether you're installing from scratch or managing mailing lists with thousands of users, qmail provides detailed information about how to make qmail do precisely what you want

qmail concentrates on common tasks like moving a sendmail setup to qmail, or setting up a "POP toaster," a system that provides mail service to a large number of users on other computers sending and retrieving mail remotely. The book also fills crucial gaps in existing documentation, detailing exactly what the core qmail software does.

Topics covered include:

Installation and configuration, including patching qmail

Moving from sendmail to qmail

Handling locally and remotely originated messages

Managing virtual domains

Logging qmail activity

Tuning qmail performance

Running multiple copies of qmail on thesame computer

Mailing list setup and management

Integrating the qmail MTA with POP and IMAP delivery

Filtering out spam and viruses

If you need to manage mailing lists, large volumes of mail, or simply find sendmail and other MTAs too complicated, qmail may be exactly what's called for. Our new guide, qmail, will provide the guidance you need to build an email infrastructure that performs well, makes sense, and is easy to maintain.

Any programmer working with text files today needs a way to deal with Microsoft® Word documents and their underlying Rich Text Format. RTF is notoriously difficult to work with, and our handy quick reference is the only book available on what many developers call "this maddeningly unstructured format." Small and easy to use on the job, RTF Pocket Guide focuses on the "workhorse" codes that programmers can't do without, including text style codes, paragraph formatting codes, and page formatting codes-- all with many examples of real use.

The current edition of Samba Pocket Reference covers Samba 2.x and the most important features of 3.0, which was under development as this book went to print. New options pertain to Samba's acting as a primary domain controller and as a domain member server, its support for the use of Windows NT/2000/XP authentication and filesystem security on the host Unix system, and access to shared files and printers from Unix clients.

Increasingly, designers need to present information in ways that aid their audience s thinking process. Fortunately, results from the relatively new science of human visual perception provide valuable guidance.
In Visual Thinking for Design, Colin Ware takes what we now know about perception, cognition, and attention and transforms it into concrete advice that designers can directly apply. He demonstrates how designs can be considered as tools for cognition - extensions of the viewer s brain in much the same way that a hammer is an extension of the user s hand.
Experienced professional designers and students alike will learn how to maximize the power of the information tools they design for the people who use them.
Presents visual thinking as a complex process that can be supported in every stage using specific design techniques.
Provides practical, task-oriented information for designers and software developers charged with design responsibilities.
Includes hundreds of examples, many in the form of integrated text and full-color diagrams.
Steeped in the principles of active vision, which views graphic designs as cognitive tools."

This easy-to-follow reference shows a variety of professionals how to use the Concurrent Versions System (CVS), the open source tool that lets you manage versions of anything stored in files. Ideal for software developers tracking different versions of the same code, this new edition has been expanded to explain common usages of CVS for system administrators, project managers, software architects, user-interface (UI) specialists, graphic designers and others. Current for version 1.12, "Essential CVS, 2nd Edition" offers an overview of CVS, explains the core concepts, and describes the commands that most people use on a day-to-day basis. For those who need to get up to speed rapidly, the book's Quickstart Guide shows you how to build and use a basic CVS repository with the default settings and a minimum of extras. You'll also find: a full command reference that details all aspects of customizing CVS for automation, logging, branching, merging documents, and creating alerts; examples and descriptions of the most commonly used options for each command; why and when to tag or branch your project, tagging before releases, and using branching to create a bugfix version of a project; and, details on the systems used in CVS to permit multiple developers to work on the same project without loss of data. An entire section devoted to document version management and project management includes ways to import and export projects, work with remote repositories, and shows how to fix things that can go wrong when using CVS. You'll find more screenshots in this edition as well as examples of using graphical CVS clients to run CVS commands. "Essential CVS" also includes a FAQ that answers common queries in the CVS mailing list to get you up and running with this system quickly and painlessly.

More often than not, the words "sendmail configuration" strike dread in the hearts of sendmail and system administrators--and not without reason. sendmail configuration languages are as complex as any other programming languages, but used much more infrequently--only when sendmail is installed or configured. The average system administrator doesn't get enough practice to truly master this inscrutable technology.

Fortunately, there's help. The "sendmail Cookbook" provides step-by-step solutions for the administrator who needs to solve configuration problems fast. Say you need to configure sendmail to relay mail for your clients without creating an open relay that will be abused by spammers. A recipe in the Cookbook shows you how to do just that. No more wading through pages of dense documentation and tutorials and creating your own custom solution--just go directly to the recipe that addresses your specific problem.

Each recipe in the "sendmail Cookbook" outlines a configuration problem, presents the configuration code that solves that problem, and then explains the code in detail. The discussion of the code is critical because it provides the insight you need to tweak the code for your own circumstances.

The "sendmail Cookbook" begins with an overview of the configuration languages, offering a quick how-to for downloading and compiling the sendmail distribution. Next, you'll find a baseline configuration recipe upon which many of the subsequent configurations, or recipes, in the book are based. Recipes in the following chapters stand on their own and offer solutions for properly configuring important sendmail functions such as:

Delivering and forwarding mail

Relaying

Masquerading

Routing mail

Controlling spam

Strong authentication

Securing the mail transport

Managing the queue

Securing sendmail

"sendmail Cookbook" is more than just a new approach to discussing sendmail configuration. The book also provides lots of new material that doesn't get much coverage elsewhere--STARTTLS and AUTH are given entire chapters, and LDAP is covered in recipes throughout the book. But most of all, this book is about saving time--something that most system administrators have in short supply. Pick up the "sendmail Cookbook" and say good-bye to sendmail dread.

The DNS & BIND Cookbook presents solutions to the many problems faced by network administrators responsible for a name server.

System Performance Tuning covers two distinct areas: performance tuning, or the art of increasing performance for a specific application, and capacity planning, or deciding what hardware best fulfills a given role. Underpinning both subjects is the science of computer architecture. This book focuses on the operating system, the underlying hardware, and their interactions. For system administrators who want a hands-on introduction to system performance, this is the book to recommend.

This open access book was prepared as a Final Publication of the COST Action IC1406 "High-Performance Modelling and Simulation for Big Data Applications (cHiPSet)" project. Long considered important pillars of the scientific method, Modelling and Simulation have evolved from traditional discrete numerical methods to complex data-intensive continuous analytical optimisations. Resolution, scale, and accuracy have become essential to predict and analyse natural and complex systems in science and engineering. When their level of abstraction raises to have a better discernment of the domain at hand, their representation gets increasingly demanding for computational and data resources. On the other hand, High Performance Computing typically entails the effective use of parallel and distributed processing units coupled with efficient storage, communication and visualisation systems to underpin complex data-intensive applications in distinct scientific and technical domains. It is then arguably required to have a seamless interaction of High Performance Computing with Modelling and Simulation in order to store, compute, analyse, and visualise large data sets in science and engineering. Funded by the European Commission, cHiPSet has provided a dynamic trans-European forum for their members and distinguished guests to openly discuss novel perspectives and topics of interests for these two communities. This cHiPSet compendium presents a set of selected case studies related to healthcare, biological data, computational advertising, multimedia, finance, bioinformatics, and telecommunications.
