We don't own the desktop yet but we do own the first ever Nobel Prize in Cool. Cool Projects that is, we've got a Linux powered rocket and a Linux powered submarine. Plus we show you how to use the iRobot Create with Linux, how to convert those old 8mm movies to DVD with Linux, and how to control your house with Linux and Mi Casa Verde. After checking out the cool projects don't miss the rest of this cool issue and read how to run Rails under Apache using Phusion Passenger, how to build a secure Squid Web Proxy, how to use OpenFiler to create an open-source network storage appliance, and if just typed "rm -rf /" find out what to do and what not to do in our continuing series of "When Disaster Strikes" articles. And don't miss our interview with Neuros CEO Joe Born or Doc's monthly words of wisdom.

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 The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model.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
