Help Me, Uncle Shawn
If you're anything like me, the holiday season is spent fixing Wi-Fi and removing spyware. Occasionally, I get to install Linux for a relative who is ready to give up Windows or needs something that will run on a circa-Windows 2000 computer (Xubuntu is usually my choice). The problem with helping friends and relatives with their computers over the holidays is that you become their first call when something goes wrong. You either can fight it or make it easier on yourself by preparing in advance.
I love Team Viewer. It's not an open-source program, but it's free for personal use with no frustrating limitations. Plus, it runs on Windows, OS X and Linux. The best part is how easy it is to use. I generally don't set up the "automatic availability" feature that logs the computer in to the Team Viewer network automatically on boot. I like to use the standard startup, which requires users to call me with the code on their screen.
The best thing about Team Viewer is how easily it handles NAT situations. Since the software connects to the Team Viewer servers, those servers act like a connection broker, meaning there are no router ports to forward and no proxies to set up. As long as the computer is on-line, you should be able to take over and help someone. Again, you might not like the ease with which you'll be able to help, but having access to a user's computer in real time is so much nicer than explaining to Uncle Harry what "right click" means.
Due to its free license for personal use, cross-platform compatibility and incredible ease of use, Team Viewer gets this month's Editors' Choice award. It's not new software, but after a stretch of holidays, I'm reminded just how nice it is to have installed on all my relatives' computers. Be sure to install the client before you leave their houses, or else be prepared to explain software installation over the phone! Get your copy at http://teamviewer.com.
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
