Parking my car this morning, the Tuesday after Labor Day weekend, I noticed that the neighborhood skate park was empty—the kids are back in school. Besides feeling a little sad that my own back-to-school days are long gone, I thought about all the ways our learning never stops.
Along those lines, an abundance of tutorials have been posted on the Linux Journal web site in the past month or two. In the spirit of continuing education, I'll take this opportunity to point out a few of these how-to articles, starting with Jos Hartman's “Building an Office Network from Spare Parts” (www.linuxjournal.com/article/6207). This tutorial outlines how Jos and some other members of his church built their office a new Linux-based network (from donated computer parts) that spans 40 kilometers. When they were finished, they'd built an office LAN, an internet server and a backup/testing server.
If you're new to office suites or have recently switched from StarOffice to OpenOffice, Ralph Krause offers two articles that might save you some time on those daily office tasks. “OpenOffice.org Address Books and Form Letters” (www.linuxjournal.com/article/6269) and “Creating Web Pages with OpenOffice.org” (www.linuxjournal.com/article/6289) explain how to perform tasks such as importing an existing address book, connecting to LDAP servers, filtering an address book with SQL queries to create form letters and creating web pages from the various applications with OpenOffice.
On the other end of the user spectrum, Mike Petullo offered the informative “Amateur Video Production Using Free Software and Linux” (www.linuxjournal.com/article/5817). Using only free software, Mike explains how to digitize analog video sources for storage and manipulation, presents tools for editing video on a computer and offers some options for publishing digital videos, including the video CD (VCD) format that is compatible with various DVD players.
Finally, for everyone wanting a laptop with Linux pre-installed from the manufacturer, well, keep waiting. Until then, however, Brian C. Lane's article, “Installing Red Hat 7.3 on a Compaq Presario 711CL Laptop” (www.linuxjournal.com/article/6291) will help you put a Linux distro on your laptop—a process he didn't find to be as dreadful as he'd heard. Brian discusses power management and how to make sure your laptop is using the correct kind, employing the acpid dæmon to track power events, drivers for LinModem support and playing encrypted DVDs.
Learning something new is a daily occurrence; be sure to look for new tutorials on the LJ site. Articles are available on the site dating back to 1994, and new ones are posted every day.

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
