What We've Been Up To
For several issues, I have sacrificed the space reserved for this column to include more interesting and useful articles, but it is time to give you an update on what is happening at Linux Journal.
Despite several setbacks, including my computer dying, LJ has improved over the past few months, as we are told over and over again in letters to the editor. However, we see much more room for improvement—and the more subscribers we have, the faster we are able to improve. Our thanks to all our subscribers!
Our greatest improvements will come from our readers. There is only so much that we can write; you, our readers, use Linux for things that we haven't thought of yet. In this issue, for instance, you'll read how Vance Petree at Virgina Power has implemented a system for managing large amounts of data using Linux systems (see page 23). In our September issue, Greg Wettstein wrote about using Linux to manage patient care for a large cancer research center. It is our policy to print at least one article each month about how Linux is being used in the real world, but we are dependent on you, our readers, to keep us informed.
We have hired several new staff members to process all our new subscription orders and to spend more time editing the articles. We have designed short monthly features with useful information, including ftp sites where information about Linux is available. Over the last few issues, we have instituted a policy of including a guide to available applicable resources of all types (including Internet sites, WWW URLs, and books) with most articles. We are now in the process of publishing a book called The Linux Sampler, filled with a mix of articles from Linux Journal, with sections on Linux history, systems administration, resources, and real world applications.
We exhibited at Unix Expo, as was covered in last month's Linux Journal, and helped make technical contacts between Linux developers and hardware and software vendors interested in Linux. We sponsored a two-day Linux Conference at Open Systems World in December, which included several short classes on a variety of topics and one full-day tutorial introduction to Linux.
Also, we like having fun with Linux just as much as the rest of you do. Many of you have seen our “My Other Computer Is a Linux System” stickers and t-shirts; we are now offering a Linux bumpersticker, and we sell other Linux-related products through our catalog. If you have other ideas for fun Linux-related items, feel free to send them to email@example.com.
Michael K. Johnson is the editor of Linux Journal, and is also the author of the Linux Kernel Hackers' Guide (the KHG).
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
