Letters to the Editor
I am at the crossroads, so to speak. Don't get me wrong—I'm a fanatic Linux user, but... First of all, some background: I work for Futurekids (South Africa), and our mission is basically to teach children and adults computer mastery skills. Currently this is done entirely on MS platforms. I started to search for alternative budget systems similar to what we use on MS, but had no luck. It seems the only use for Linux in the classroom is for Internet access and file/printer sharing.
This brings me back to the underlying problem. If we truly want to promote Linux, we must start with the younger generation—the adults of tomorrow. If we can work together to implement a solid education program based on the Linux platform, I believe we will have success. The net result? Children use Linux at school—they get frustrated with Windows at home—and eventually more and more home Windows systems migrate to the Linux platform. But we need this educational system first. To start, the software developers must begin producing “kids” programs—and please, not another flash card program—but programs that make use of multimedia to teach children how a mouse works, how the keyboard works, then progress to Encarta-like encyclopedias, etc.
Dear Linux Developer Community—there is your challenge!

I have been using computers for many years, so I am no stranger to the difficulties associated with installing a new OS. But to make claims in your magazine that so far are false, such as the ease of loading Caldera, has put me off both your magazine and Linux in general. I have tried to contact the company: the person at the 1-888 number could easily be replaced by a tape machine, technical-support lines requested I pay more money to make their product work, and I have received no response from e-mail support. I write to you because I read a review in your magazine, and dopey me, I thought someone there used the software before they wrote about it.

Sorry you had problems. In actuality, at least four people here at the office, including the reviewer, used the Caldera LIZARD install successfully with only the one problem discussed in the review. Since that time, we did try to install it on an old machine with a strange configuration, and LIZARD hung up. We switched to the LISA install and it worked fine, installing everything off the CD-ROM without a problem. Took longer than LIZARD, but was still fairly easy. Writing an easy install that includes all possible configurations of hardware, both old and new, is not an easy task —Editor
First off, I would like to say good job with your magazine. I always look forward to the new issue hitting our shelves in my store. I work for Barnes and Noble booksellers, and that's what the other part of this letter is about. I wanted to inform you that due to the support of our Customer Relations manager, and of the store in general, we have started a Linux Users Group through my local store. We meet in the store once a month (the third Tuesday of every month, for those of you in the Lakewood/Long Beach, CA, area). It has quickly grown to be the most popular group in our store, even surpassing the regular reading groups. I hope this trend continues and we see more user groups popping up. Thanks again.

I have to disagree with Phil Hughes' position in “Is KDE the Answer?” in October's Linux Journal. At the end of the article, Phil states that we should all jump on the KDE bandwagon because KDE is further ahead and is the default on more distributions. He also states that one standard GUI is better than two for appliance users.
I think this is wrong. First of all, there is something to be valued in diversity, as diversity breeds strength. If one day KDE runs into a brick wall and cannot further advance, we'd still have GNOME. Furthermore, if we all jumped on the product that was furthest ahead, Linux would not exist today.
Second, I see no advantage to giving appliance users (or newbies, or any other user) only one interface. While this may require less mental exertion on the part of the user, it will also lead to a bland, homogenized world. A different, novel interface may actually appeal to some of the appliance users.
Phil also mentions offering “one standard GUI rather than two”. This is like saying the US has only two political parties. I use neither KDE nor GNOME, because neither works well for me. Just try running either on a slower Alpha with a TGA card, and you'll know what I mean. Instead I use icewm, which I think is far superior to either. I've used other window managers such as mwm, amiwm and twm, and find all of them far faster, more stable and in almost all ways superior to KDE and GNOME, especially on low-end hardware.
By saying that we should all jump on the KDE bandwagon, Phil is saying that we should all fit ourselves into KDE's mold rather than finding and developing the tools that fit us. In my book, KDE is not the answer.

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
