First published in 1971 and now reissued in paperback for the first time, First Mail West recounts the colorful history of stagecoach lines on the Santa Fe Trail during the height of overland traffic from 1850 to 1879. Desert, rain, snow, wind, outlaws, Indians, buffalo stampedes, and business competitors challenged, and sometimes scuttled, the operation of stage lines between Missouri and New Mexico. The author describes the topography, roads, rolling stock, stations, accommodations, and natural and human dangers along the trail, and analyzes the fierce competition between independent lines for passenger traffic and federal mail contracts.

Express, Mail & Merchandise Service describes rail express service and merchandise traffic on railroads from the early 1900s through 1960s when railroad personnel handled packages and merchandise - everything from baby chicks and cornflakes to money and machinery - and got them to their final destination. A wonderful historical reference for modelers and railfans alike.

A cutting-edge media history on a perennially fascinating topic, which attempts to answer the crucial question: Who is in charge, the servant or the master? Though classic servants like the butler or the governess have largely vanished, the Internet is filled with servers: web, ftp, mail, and others perform their daily drudgery, going about their business noiselessly and unnoticed. Why then are current-day digital drudges called servers? Markus Krajewski explores this question by going from the present back to the Baroque to study historical aspects of service through various perspectives, be it the servants’ relationship to architecture or their function in literary or scientific contexts. At the intersection of media studies, cultural history, and literature, this work recounts the gradual transition of agency from human to nonhuman actors to show how the concept of the digital server stems from the classic role of the servant.

Postfix is a Mail Transfer Agent (MTA): software that mail servers use to route email. Postfix is highly respected by experts for its secure design and tremendous reliability. And new users like it because it's so simple to configure. In fact, Postfix has been adopted as the default MTA on Mac OS X. It is also compatible with sendmail, so that existing scripts and programs continue to work seamlesslyafter it is installed.Postfix was written by well-known security expert Wietse Venema, who reviewed this book intensively during its entire development. Author Kyle Dent covers a wide range of Postfix tasks, from virtual hosting to controls for unsolicited commercial email.While basic configuration of Postfix is easy, every site has unique needs that call for a certain amount of study. This book, with careful background explanations and generous examples, eases readers from the basic configuration to the full power of Postfix. It discusses the Postfix interfaces to various tools that round out a fully scalable and highly secure email system. These tools include POP, IMAP, LDAP, MySQL, Simple Authentication and Security Layer (SASL), and Transport Layer Security (TLS, an upgrade of SSL). A reference section for Postfix configuration parameters and an installation guide are included.Topics include:Basic installation and configurationDNS configuration for emailWorking with POP/IMAP serversHosting multiple domains (virtual hosting)Mailing listsHandling unsolicited email (spam blocking)Security through SASL and TLS From compiling and installing Postfix to troubleshooting, Postfix: The Definitive Guide offers system administrators and anyone who deals with Postfix an all-in-one, comprehensive tutorial and reference to this MTA.

Simple Network Management Protocol (SNMP) provides a "simple" set of operations that allows you to more easily monitor and manage network devices like routers, switches, servers, printers, and more. The information you can monitor with SNMP is wide-ranging--from standard items, like the amount of traffic flowing into an interface, to far more esoteric items, like the air temperature inside a router. In spite of its name, though, SNMP is not especially simple to learn.O'Reilly has answered the call for help with a practical introduction that shows how to install, configure, and manage SNMP. Written for network and system administrators, the book introduces the basics of SNMP and then offers a technical background on how to use it effectively. Essential SNMP explores both commercial and open source packages, and elements like OIDs, MIBs, community strings, and traps are covered in depth. The book contains five new chapters and various updates throughout. Other new topics include:Expanded coverage of SNMPv1, SNMPv2, and SNMPv3Expanded coverage of SNMPcThe concepts behind network management and change managementRRDTool and CricketThe use of scripts for a variety of tasksHow Java can be used to create SNMP applicationsNet-SNMP's Perl moduleThe bulk of the book is devoted to discussing, with real examples, how to use SNMP for system and network administration tasks. Administrators will come away with ideas for writing scripts to help them manage their networks, create managed objects, and extend the operation of SNMP agents.Once demystified, SNMP is much more accessible. If you're looking for a way to more easily manage your network, look no further than Essential SNMP, 2nd Edition.

Netflix has come a long way since 1997, when two Silicon Valley entrepreneurs, Marc Ran­dolph and Reed Hastings, decided to start an online DVD store before most people owned a DVD player. They were surprised and elated when launch-day traffic in April 1998 crashed their server and resulted in 150 sales. Today, Netflix has more than 25 million subscribers and annual revenues above $3 billion. Yet long- term success-or even survival-is still far from guaranteed. Journalist Gina Keating recounts the absorbing, fast-paced drama of the company's turbulent rise to the top and its attempt to invent two new kinds of business. First it engaged in a grueling war against video-store behemoth Blockbuster, transforming movie rental forever. Then it jumped into an even bigger battle for online video streaming against Google, Hulu, Amazon, and the big cable companies. Netflix ushered in such innovations as DVD rental by mail, a patented online queue of upcom­ing rentals, and a recommendation algorithm called Cinematch that proved crucial in its struggle against bigger rivals. Yet for all its success, Netflix is still a polariz­ing company. Hastings is often heralded as a visionary-he was named Business Person of the Year in 2010 by Fortune-even as he has been called the nation's worst CEO. Netflix also faces disgruntled customers after price increases and other stumbles that could tarnish the brand forever. The quest to become the world's portal for pre­mium video on demand will determine nothing less than the future of entertainment and the Internet. Drawing on extensive new interviews and her years covering Netflix as a financial and entertainment reporter, Keating makes this tale as absorbing as it is important.

WINNER, 2004 NATIONAL OUTDOOR BOOK AWARD! (Outdoor Literature) Who hasnt wanted to get away from cell phones, e-mail, roads, and traffic? And what better place to escape our wired world than the far northwestern corner of Canadas Northwest Territories and a river that flows through uninhabited country, 400 miles to the Arctic Ocean. But what if your canoeing partner brings along a satellite phone to use in case of an emergency? And, struck by the novelty of anywhere-on-earth communication, he proceeds to use the phone to check in with his law office, his wife, kids, sisters, father, and friends? Noted wilderness traveler and author Ted Kerasote deals with just such a situation as he journeys along the Horton River through the largest ice-free, roadless area left on Earth, a stunning wilderness of grizzly bears, caribou, and migrating birds. Between navigating rapids, slipping around musk ox and grizzlies, and being pinned down by Arctic storms, the two friends prod each other into a finer understanding of love, marriage, parenting, and the meaning of solitude in an increasingly wired world. Contrasting his own experiences with those of the regions earliest explorers--Sir John Franklin and Vilhjalmur Stefansson--Kerasote provides a compelling and humorous take on how travelers from any age adjust to being away from their civilizations and how getting "out there" has inevitably changed but has also remained the same--especially if you shut off the phone.
