Ultimate Is in the Eye of the BogoMip Counter
In this year's Ultimate Linux Box article, LJ Technical Editor Don Marti explains how you too can be the first on your block to build a machine that develops over 9,000 BogoMips. But now that machines with processor speeds of 1-2GHz, and even multiple processors, and gigabytes of RAM are quite common, building the Ultimate Linux Box isn't only about sticking the fastest and the biggest together (although that's still a lot of fun). Therefore, in addition to making recommendations on cards, motherboards, hard drives, etc., Don takes a look at some of the finer points of box building, such as box real estate, the advantages of building over buying and cooling. Though it's certainly a labor of love, Don has been working with vendors and others for many months now in order bring you building advice that has real value, whether you're building a computer from top-of-the-line components or one that represents a more modest budget.
Speaking of modest budgets, in Cooking with Linux this month, Marcel takes an alternative view of the idea of the Ultimate Linux Box, showing how you can obtain greater speed from humble resources by lightening the software load. He samples some lightweight software that includes a window manager with abundant features, a web browser and office software that manage to run all together in less than 32MB of memory.
Last month we ran an update to Charles Curley's November 2000 article on bare metal recovery. This month, Joey Hess shows how to avoid conscious backups all together by keeping not only your projects, but your entire home directory, in CVS. Joey admits the idea is a sure sign of an unbalanced mind, but that it also has many advantages, not the least of which is distributed backups.
Also in this issue, we have a report from John “maddog” Hall on his recent visit to the state of Rio Grande do Sul, Brazil to attend the Fórum Internacional de Software Livre. Jon discovered that in Brazil they are taking the concept of world domination quite seriously, and the state of Rio Grande do Sul has had laws favoring the use of open-source software by government and business for some time now. His article points out a number of highly worthy free software projects.

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
