Instant gratification is quite gratifying. Because I haven't yet perfected the Arduino Wetwired Electronic Semi-Omniscient Memory Enhancer (A.W.E.S.O.M.E. for short), we figured the best way to serve our fast-paced world was to have a Web Development issue. Let's face it, if you want to see the weather forecast, you visit a weather Web site. Waiting for the six o'clock news takes too long, and I'm not willing to admit I'm old enough to watch The Weather Channel. The Web, along with its Twitter-esque companions, is currently the fastest way to get information to the masses. And we want to help.
Reuven M. Lerner starts things off with the back end of the Internet. No, I don't mean my personal Web site; I mean databases. This month, Reuven looks at PostgreSQL 9.0. Even if you're a MySQL fan, PostgreSQL is hard to hate, and Reuven explains why. Dave Taylor is hard to hate as well, and this month, he takes us back to our youth with the second part of his series on creating Mad Libs. I did my first Mad Lib when I was [ANY_NUMBER] years old, while I was [ACTIVE_VERB] in [PLACE], and it was really [DESCRIPTIVE_ADJECTIVE].
Kyle Rankin and Mick Bauer teach us about servers this time around. Kyle describes creating a DNS server as part of his series “Building Your Own Personal Server”. DNS can be complicated, but Kyle walks through setting up the industry standard, BIND. Mick is on the opposite end of the spectrum with his “Interview with a Ninja”. What Kyle shows how to build, Mick and his ninja talk about hacking into—good information from both guys.
Some of us aren't hard-core programmers, but we still need to get information onto the Web and have it look good and perform well. That's when content management systems are awesome. Michael Connors introduces Zotonic, a content management system based on Erlang. If you're new to the idea of a CMS, you'll want to check out Zotonic, which is a CMS, but also a Web framework. Drupal, on the other hand, is a traditional CMS that is used in thousands of Web sites across the planet. Our own LinuxJournal.com Web site runs Drupal, and this month, Webmistress Katherine Druckman interviews Angela Byron, the co-maintainer of Drupal 7. Reading the interview will teach you a bit about Drupal, but even more than that, it will give you a behind-the-scenes glimpse at managing a large open-source project. Drupal 7 sounds like a huge step forward in usability, and it's Angela's job to make sure that step doesn't trip and fall along the way.
I know some of you are annoyed by the Web and its dependence on mouse clicking. I suspect Kyle Rankin and his terminal window are as well. James Walker feels the same way and introduces Drush, a command-line interface for Drupal. Sure, a nice GUI is great, but sometimes it's hard to beat a simple command line. James demonstrates a click-free way to interact with Drupal. It's pretty cool for those of us addicted to the command line.
If you're not interested in the Web at all, we haven't forgotten you this month. Whether you want to make a quick user interface with Qt (Johan Thelin shows how) or manage and convert your e-book collection with Calibre (Dan Sawyer explains the process), this issue is bound to please. We also have a review of D-Link's Boxee Box by yours truly, and we have instructions on how to find yourself—with Google Maps (Mike Diehl shows how to manipulate the API).
This is a very fun issue, and until my A.W.E.S.O.M.E. is fully developed, turning the page and reading is the best way to assimilate the information. I'm not sure whether my Arduino brain implant will be ready for the Cool Projects issue, but those interested in beta testing should feel free to contact me. Just think real hard and the message should get to me, assuming my A.W.E.S.O.M.E. is working correctly. Until then, have a [DESCRIPTIVE_ADJECTIVE] [TIME_PERIOD], and we'll [ACTION_VERB] you next month!

Don't let his silly hairdo fool you, he's a pretty ordinary guy and can be reached via e-mail at email@example.com. Or, swing by the #linuxjournal IRC channel on Freenode.net.
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
