Current_Issue.tar.gz - The Issue <emphasis>You</emphasis> Write
That's right, it's our annual Readers' Choice issue of Linux Journal. Every year, we ask you, our readers, to share what you think really stood out over the past year. And, then we tell you about it. Certainly, it seems like an easy way for us to avoid writing articles for you, but rest assured, the Readers' Choice issue isn't our excuse to take a cruise for a month and leave you to your own wiles. It's more like a community issue. You give, we give, and everyone is happy. Well, maybe not everyone. Emacs users for instance, or perhaps KDE users. But, I won't ruin the results for you.
In fact, with the Readers' Choice theme this month, it allows our columnists a little more flexibility in regard to what they write, and they didn't disappoint. Marcel Gagné shows us a handful of ways to install and test products that you may have never considered before. From virtual machines to jumpboxes, if you want to try out some server applications, you'll want to read this month's Cooking with Linux column.
Kyle Rankin has another go at Lightning Hacks this month and gives us four quick but useful tips that make life a bit easier behind the keyboard. Kyle claims he got the idea for Lightning Hacks from the common Lightning Talks featured at many conferences. I suspect he's just jealous of our daily video tech tips over at LinuxJournal.com. Sadly, I don't have any way to validate my claim. Speaking of validation (nice segue, no?), Reuven M. Lerner shows us how to validate HTML code. Linux users are big fans of open standards. Unfortunately, we sometimes fail to follow them ourselves. Reuven aims to change that this month, so be sure to read his column to learn more.
Last year, we did an issue dedicated to high-performance computing. We got a lot of positive feedback from that issue and thought the Readers' Choice issue would be a great place to put in a High Performance section. Tom Lehmann demonstrates how easy it is to create your own computer cluster. We met Tom at the Supercomputing conference and asked him to prove it was easy to set up a cluster. I think I owe him a soda or something, because this month, he shows us step by step how to set up a Rocks cluster of our very own.
On the programmer's side, Matthew Russell is back this month showing off Dojo's Grid Widget. Sometimes displaying large amounts of data is difficult, but Dojo makes it a bit easier. If system administration is your thing, be sure to check out Jason Ellison's article on SNMP monitoring with Nagios. There's no such thing as too much monitoring data, and even if there were, Dojo can help us display it!
To finish up the Readers' Choice issue nicely, we have Dave Taylor's script-fu to help figure out the odds in the game show, Deal or No Deal. I don't think it's quite as frowned upon as counting cards in Vegas, but I'm not sure Howie Mandel would look too kindly on a contestant with a laptop calculating odds—perhaps if the script could be ported to an Android handset....
In the end, this issue and every issue is all about you, the reader. Enjoy the Readers' Choice issue. If your tastes line up with the majority of voters, you can bask in the comfort of commonality. If your application of choice didn't even make the list, you can smugly assure yourself the rest of the world just isn't as enlightened. After all, as Linux users, we're used to going against the grain. It has worked for us so far; I see no reason to change now.

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
