Freedom Technology Center To Open
The Freedom Technology Center, a new non-profit IT training and education facility in Mountain View, California, will open on Saturday, November 22nd, with a free one-day class on e-mail security, "Protecting E-mail Users from Viruses, Spam and Other Threats."
(Disclaimer: Linux Journal editor in chief Don Marti is a cofounder of the Freedom Technology Center.)
The second and third scheduled classes at the center cover the material for the Linux Professional Institute's LPI 101 and LPI 102 certification exams. The LPI 101 class is scheduled for December 1-5, and the LPI 102 class is scheduled for December 8-12.
The instructor for all three classes, Jim Dennis, has conducted Linux training for such firms as Motorola, SGI, Cadence, Wells Fargo, and DTT. He is the co-author of Linux System Administration (New Riders, 2000) and numerous magazine and Web articles. "If you spend one day covering the latest software and filtering approaches, you can really lock out the majority of spam and virus threats", Dennis said. "I cover what works and what doesn't."
The class is intended for full or part-time system administrators who are responsible for the function and security of e-mail for a small company or group.
Whether or not you use an open-source mail server internally, the filtering techniques covered can keep users safe from e-mail attacks, and it is possible to do so without upgrading or reconfiguring the existing mail server or mail clients.
In the LPI classes beginning in December, the topics to be covered include everything from installation and command basics to network administration, security and advanced troubleshooting.
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
