Fun with Hardware
From 64-bit servers to console conversion projects, your Linux platform choices are better than ever.
by Don Marti
Running Linux makes you smarter, and we've got proof. In his article on Nagios on page 52, Richard C. Harlan explains how John Deere integrated its diverse server management needs under the thumb of one Linux-based project, for a small budget.
Other cluetrain-riding people at a variety of companies talked to Doc Searls about the new balance of innovation power between informed Linux-using customers and their vendors (page 38). Freedom is changing companies behind the scenes, and thanks to your discreet tips, Doc is watching it better than anyone.
This issue also includes the year's best Linux hardware news so far. The big cheeses of the information technology industry are building servers based on AMD's new AMD64 architecture, which you may know as linux/arch/x86_64. In an interview on tazaa.info, AMD CEO Hector Ruiz included Linux as one of only two “operating systems that matter”, and our favorite OS was the first one released for AMD64.
You can get an idea of AMD64's abilities, and those of the Newisys two-way server that's among the first Opteron products on the market, in Michael Baxter's first look on page 58. Michael is the man to ask about Linux in the electronic design automation industry, and the new AMD architecture is already attracting attention from Cadence and others as a way to replace expensive 64-bit RISC UNIX.
Our other featured hardware article this issue covers Microsoft's Xbox video game system. On page 44, Michael Steil explains how making the Xbox run Linux is not only fun but actually useful. Try it. Upgrading an Xbox is a great way to learn about the boot process and is cheaper than a single-board computer for hobbyist embedded projects. Cut back on the coffee the day you solder those two little pads together, though.
If your web site uses free software exclusively, you might not realize how big of a deal CMF for Zope (page 14) really is. Proprietary content management systems have high-priced licenses and still require you to do substantial customizing. This might be the article that makes you a web hero at work, so pay attention.
This issue also hosts a cross-platform development-tool cage bout. Will your next project use the promising new Mono (page 74) or the reliable wxWindows (page 90)? Both are free as in Dmitry, so you can easily try both. Finally, contributor Josh Rabinowitz told me that he got hooked on using the man page index, shown in his article “How to Index Anything” (page 82), before he was even done with the article. Imagine searching all your man pages, Linux Journal archive CDs and old mail with one tool. I'm going to try it out.

Practical Task Scheduling Deployment

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
