This book is about the advanced, object-oriented NEXTSTEpTM user envi ronment for NeXT and Intel-based computers. It is intended for those who already own a computer running NEXTSTEP and want to quickly learn what it can do and how to get the most out of it with the least effort. It's also for those who are considering the purchase of NEXTSTEP but want to learn more about how it works before making an investment. Why a book on NEXTSTEP? When I set out to learn how to use NEXT STEP several years ago, I found it extremely difficult to find information from the usual sources, such as books, magazines, user groups, and autho rized dealers. NEXTSTEP users were scarce and finding a computer store that sold NeXT-related products was even more rare. There were also only a handful of NeXT user groups in existence and those that did exist met so far away that joining one of them was impractical. The manuals I received from NeXT were helpful, but I had the feeling there must be something more to it than what was written in the User's Reference. It didn't describe many of the shortcuts that experienced users had found or the public domain and shareware utilities that were popular and how I could use them to make my work even easier and more fun.

Do you think that the Ozone Hole is a grunge rock club? Or that the Food Web is an on-line restaurant guide? Or that the Green Revolution happened in Greenland? Then you need The Cartoon Guide to the Environment to put you on the road to environmental literacy. The Cartoon Guide to the Environment covers the main topics of environmental science: chemical cycles, life communities, food webs, agriculture, human population growth, sources of energy and raw materials, waste disposal and recycling, cities, pollution, deforestation, ozone depletion, and global warming—and puts them in the context of ecology, with discussions of population dynamics, thermodynamics, and the behavior of complex systems.

This IBM® Redbooks® publication describes important networking concepts and industry standards that are used to support high availability on IBM System z®. Some of the networking standards described here are VLANs, VLAN trunking, link aggregation, virtual switches, VNICs, and load-balancing. We examine the various aspects of network setups and introduce the main Linux on System z networking commands and configuration files. We describe the management of network interface parameters, assignment of addresses to a network interface, and usage of the ifconfig command to configure network interfaces. We provide an overview of connectivity options available on the System z platform. We also describe high availability concepts and building a high availability solution using IBM Tivoli® System Automation. We also provide the implementation steps necessary to build a redundant network connections set up between an IBM z/VM® system and the external network switches using two Open Systems Adapter-Express 3 (OSA-Express 3) adapters with 10 Gb Ethernet ports. We describe the tests performed in our lab environment. The objectives of these tests were to gather information about performance and failover from the perspective of a real scenario, where the concepts of described in this book were applied. This book is focused on information that is practical and useful for readers with experience in network analysis and engineering networks, System z and Linux systems administrators, especially for readers that administer networks in their day-to-day activities. For additional reading: A Technote is availalble that explains changes to using channel bonding interfaces introduced with SLES 11 SP 2.
