December 2013 Issue of Linux Journal: Readers' Choice
As we wave a fond farewell to 2013, we close out the year with one of our favorite issues. I know, I often tease about being lazy and having the readers write the Readers' Choice issue, but I only do that because it's absolutely true! Seriously though, this is one of our favorite issues because we get to hear from you. Some of your feedback was expected, some was a little surprising, but it was all appreciated. If you want to see how you line up with your fellow readers, you can skip ahead to the Readers' Choice article, but if you do, you'll be missing out on tons of great content!
Reuven M. Lerner, for example, gives us his annual summary of the most interesting books he's read. Whether you're looking for a nice holiday read or want to make sure you haven't missed any gems this past year, Reuven shares his insight from his library. Dave Taylor follows up with another column on the library of tools available in the ImageMagick suite. If you need to edit photos, especially in an automated or bulk way, the command-line image editing tools Dave describes are invaluable.
SSH is a tool just about every geek knows well. There are countless tutorials for creating SSH key pairs for adding security (and convenience) to server logins, but that same layer of security comes with the danger of stolen key files. Kyle addresses the issue of SSH security while keeping as much convenience as possible. SSH Agent may be the best of both worlds: convenience and security. I follow Kyle's article with a how-to for implementing LVM. Logical Volume Manager adds convenience and expandability to your system with far less complexity than it might seem. If you've ever been scared of LVM, be sure to check out my column.
Jim Hall helps point out the warts in open-source software this month with his article on usability testing. If you're tired of hearing how hard the GIMP is to use because of its interface, Jim's article will interest you. As longtime geeks, it's often easy to overlook an interface's shortcomings. This article helps us take off our rose-colored glasses and see our programs for what they are.
We also had the opportunity to interview a Linux user, musician and developer: Australis. I always love to meet folks who use Linux on a daily basis for their livelihoods, and Fred Mora had the fortune of interviewing the indie artist. If you like to hear how Linux and open source can influence and empower artists, you'll really enjoy the interview. I know we sure did.
I don't normally mention Doc Searls' closing column in my Current_Issue column, but this month, he brings up an interesting discussion about the tech world, and Linux Journal specifically. In a male-dominated industry, Linux Journal is owned and managed by women. What does that mean in the bigger picture? Doc starts a great discussion on an important topic.
Of course, the big story this month is the Readers' Choice article, or as we're tempted to call it, "The Raspberry Pi Award Ceremony!" I probably should have said "spoiler alert", but I'm sure it's no surprise that the Raspberry Pi is still very popular among readers. Thankfully, there's a boatload of other categories, all of which were chosen by you. This year, not only did readers cast the votes, but there was an entire nomination round as well. Thank you to everyone who participated. You made this issue an awesome one.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
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
