Current_Issue.tar.gz - Linux Means Business--and Fun
This month, we focus on Linux in the enterprise. No, not that Enterprise (I'm pretty sure I used the Star Trek joke last year). We're talking about large deployments of Linux. One awesome thing about such an issue focus is that it really doesn't apply only to folks administering huge networks. Most of the features scale down quite nicely for those of us administering a closet in our bedroom, a server rack in the basement or just a database on the couch. In fact, Reuven M. Lerner talks about CouchDB this month. Silly name aside, CouchDB is becoming more and more popular as a non-relational database. If you like what Canonical is doing with its syncing technology in Ubuntu One, you'll want to check out the underlying framework it uses—first and foremost, CouchDB.
Bill Childers has his head up in the clouds again, and this time he shows us how to set up our own cloud with Eucalyptus. Sure Amazon and that ilk are great if you don't have your own servers, but if you already own the hardware, why not make your own cloud? Bill shows how. If you already have your servers set up, perhaps you're just at the point when you need to administer them, whether they're in the cloud or not. Kyle Rankin, an enterprise sysadmin himself, presents a few more tricks of the trade with a series of crafty ways to use SSH.
Perhaps you're not interested in setting up a cloud, and you just want to make your existing servers (or cloud) do something useful. We have plenty of that this month too. Dave Taylor continues his series on scripting HTML forms, Michael Nugent talks about MySQL replication, and Daniel Bartholomew discusses SQL vs. NoSQL (where we get to watch Daniel battle his own version of Point/Counterpoint). Regardless of what services you offer on your servers, you need to be able to monitor them. Also in this issue, Paul Tader shows us Zabbix, a cross-platform monitoring tool that takes much of the sting out of setting up monitoring.
For some of us, Linux in the enterprise is only a dream we'd like to see come to fruition. We labor over our Linux machines at home, yet at work, we're stuck with proprietary operating systems and closed-source programs. Jeramiah Bowling compares Microsoft Windows and Linux in the enterprise, pulling the rug out from under some common misconceptions and providing some real data we might use to demonstrate where Linux might be a better fit. Unfortunately, even if the logic is clear, sometimes politics are a bigger stumbling block than feasibility. Avi Deitcher writes about the whole process of introducing open-source software and ideals to business folks. It's often a difficult undertaking, and Avi has some smart tips.
What if enterprise Linux doesn't interest you at all? Don't worry; we understand. And, even if you work on Linux in the enterprise, sometimes it's nice to come home and enjoy your own Linux machines without worrying about clouds, monitoring, scalability and other 9-to-5-sounding words. Jono Bacon introduces us to Quickly this month. Quickly is a program that supplies templates, tools and a framework to allow quick desktop application development. If you've ever wanted to make your own applications, but didn't want to go through the frustration of the traditional development model, Quickly might be right up your alley.
We also have a review of the Coyote Point Application Balancer, Dirk Elmendorf covers desktop document scanning, and John Knight introduces some fresh projects. Plus, there are all the other articles that make Linux Journal such a fun magazine for geeks. So whether you're building your own cloud, tweaking your existing infrastructure or just killing time on the command line, this issue has you covered.
Shawn Powers is the Associate Editor for Linux Journal. He's also the Gadget Guy for LinuxJournal.com, and he has an interesting collection of vintage Garfield coffee mugs. Don't let his silly hairdo fool you, he's a pretty ordinary guy and can be reached via e-mail at firstname.lastname@example.org. Or, swing by the #linuxjournal IRC channel on Freenode.net.
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
