This new book from Walter Goralski and Morgan-Kaufmann, The Illustrated Network: How TCP/IP Works in a Modern Network, updates the classic TCP/IP Illustrated from W. Richard Stevens to apply to 2008 equipment, OSes and routers. The book contains 330 illustrations, such as screenshots and topology diagrams, which portray examples from a real, working network configuration including servers, routers and workstations. The publisher says the illustrated approach “allows the reader to follow the discussion with unprecedented clarity and precision”. The Illustrated Network is device- and platform-agnostic.
If you're setting off on an open-source enterprise-automation project, first download Apache's OFBiz, and then grab the new book Apache OFBiz Development: The Beginner's Tutorial. The book is authored by the team of Rupert Howell and Jonathan Wong and published by Packt. Apache OFBiz contains ERP, CRM, POS, e-business and e-commerce, SCM, MRP, CMMS/EAM and other applications. The book's design is to give newcomers a hands-on introduction to OFBiz, covering the main modules and employing illustrated examples that show how to build applications rapidly. In addition to the Model-View-Controller framework, readers will gain working knowledge of Widgets, Entities and the Service Engine. Finally, readers will learn how to tweak OFBiz as well as get tips on performance enhancement and development.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
