Urgent: Help Shawn Powers & Family
Today is a day of grief for Linux Journal. This afternoon, Associate Editor Shawn Powers' home burned down — though we don't know many details yet, we do know that Shawn, his wife Donna, and their three girls were not home at the time, but their pets were lost.
Shawn is one of the warmest, kindest, and most big-hearted people we know. Anyone who has met him, in the offline world or online knows that he is an amazing person, and is constantly focused on others. We at Linux Journal are privileged to know him, and compelled to offer whatever assistance we can in this troubled time.
The Linux and Open Source community is filled with generous individuals, and we are asking those who are moved to offer their help to Shawn and his family to please do so. We have set up a ChipIn page at helpshawnpowersfamily.chipin.com to collect donations — it is a testament to the generosity of this community that in less than three hours, almost $2,500 has been raised.
We know technology donations will be greatly appreciated, and if you have equipment you would like to donate, please email Linux Journal's publisher, Carlie Fairchild.
Shawn has been posting updates to Twitter and photos to Natuba, for those who would like to follow the situation. Please feel free to leave words of encouragement and solidarity in the comments here — you can also do so on his Facebook page. Update: Shawn posted additional details to his blog from his office earlier this evening.
Please know, this isn't Shawn asking for help — he has no clue we've organized anything. This is the Linux Journal team, as a family, asking our community to aid one of our own. We appreciate your generosity, and we know Shawn will too.

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
