1-17: Understanding, the new book by Richard Saul Wurman. (www.understandingusa.com)

Prior to what Omaha Steaks (http://www/omahasteaks.com/) believed would be the start of their busiest on-line shopping time of year, the 2000 holiday season, they decided to revamp their web site to accommodate an estimated one million customers. eOne Group (http://www.eonegroup.com/), an Omaha-based eCommerce software and service provider, worked with Omaha Steak's internal IT department to build a web site that could be hosted on-site, integrated into back-end systems as well as provide advance delivery schedules and multiple ship-to-address options.
As the basis of the new web site, eOne used their Java-based, hardware-independent development application called jCommerce. Being an open-architecture application, jCommerce runs on almost any platform and can be customized for each individual customer and situation. As jCommerce provided the database-driven features Omaha Steaks wanted, including easily customized XML and XHTML tags and accessible userinterfaces, the software choice seemed easy enough; the real decision centered on what platform to use.
Chad Bukowski, chief architect at eOne, characterizes Omaha Steaks as a traditional, family-owned and operated business since 1917. He was unsure how receptive the company would be of the open-source philosophy and business model Linux offered, the platform eOne actively supports for their jCommerce software. But he also knew that their final decision would be based on price and performance and not necessarily the name attached to the platform. The benchmark stress and load tests were done on RS/6000 M80 IBM systems, their current AS/400 system and Dell Intel boxes running Red Hat Linux 6.2. During the test, the AS/400 system slowed when the number of separate, simultaneous customer orders headed toward 50; the RS/6000 topped out around 150-200 orders. The Dell boxes, according to Bukowski, processed 250-400 orders with little taxation.
Impressed by the benchmark results of Linux, its scalability and because Omaha Steaks “wanted something that wasn't tied to IBM”, Bukowski said that they were eager to launch their new web site running on Linux. Jeff Carter, CTO of Omaha Steaks, said that four main considerations made Linux the most viable option: price performance of the Dell servers versus the IBM offerings ($8,000 per machine for Dell vs. $250,000 per machine for RS/6000, plus licensing fees); overall acceptance and performance of Linux in the Internet space; stability of Linux versus NT on the Intel platform; and easy integration of Linux with legacy systems.
The new site went live in fall 2000, after a 60-day setup period. So far, both Omaha Steaks and eOne are pleased with the results. Reboots are nonexistent, and Bukowski says the system “is singing right along”. Customers are satisfied with the simplified and versatile ordering procedure, and Omaha Steak employees have had no problems adapting to the new system. Carter underlines the importance of having a system that can be maintained with internal resources: no Java programming is necessary to maintain the parameter-driven site. Of Omaha Steak's relationship with eOne Group, jCommerce and Linux, Carter says, “No one else in the marketplace had all of these thing to offer.”

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
