Eclecticism for the Masses
Being eclectic is a good thing, even though the word often is said in a tone of voice usually reserved for words like “lice” and “spellcheck”. The Linux Journal web site, however, prides itself on being a compendium of topics related to open-source, free software and, of course, Linux. In any given week, a visitor might find articles ranging from hardware reviews to lessons in spam filtering to how-tos for building one's own VPN gateway. It may sound obvious, but a lot of people are using Linux to do a lot of different things. Our site attempts to provide articles that explain how to do what you're dying to try, as well as introduce topics and projects with which you might not be familiar. We might even be able to help you win an argument.
Say, for instance, someone is giving you the old line about Linux being too hard to use. Point them to “Interview with a Grandmother” (www.linuxjournal.com/article/6562 ), in which Joe Klemmer talks to his mom about her experience with OEone's HomeBase Linux system. Not only is it so easy the proverbial grandmother can use it, this real grandmother uses her computer “ever so much more than before”.
Back in early January 2003, senior editor and business reporter Doc Searls prognasticated Linux and open-source events for 2003 in “Which Major PC Vendor Will Sell Desktop Linux First?” (www.linuxjournal.com/article/6548). As the title indicates, Doc feels this is the year Linux on the desktop will show up in a major way, thanks to the support of some major vendors. Is he right? Also, be sure to check out the predictions and comments offered by readers at the end of the article.
Finally, it wouldn't be LJ if we did not have at least one security article. In “Security with PHP Superglobals” (www.linuxjournal.com/article/6559), David Lechnyr describes his desire to make after-the-deadline on-line reservations for ski equipment and how easy that turned out to be thanks to the site's use of GET statements. If the site had used PHP superglobals, which allow users “to specify which variables received by a specific method should be used”, it would have been more secure, but he wouldn't have had skis waiting the next morning.
Just like having a music collection with a little Ella, a little Hank, some Buzzcocks and the essential Who is a good thing, so is having a web site with a little bit of everything—I mean, you'd rather be eclectic than boring, right?
Remember to check the Linux Journal web site often; new articles are posted daily. If you want to write an article for us, drop a line to email@example.com.

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
