Letters to the Editor
I loved your recent feature on Tcl/Tk programming. Please keep finding top quality writers like Stephen Uhler. I also appreciated the Perl article. But the reason LJ is so great is that it applies high editorial standards to discussion of topics that are typically served by nothing more formal than FAQs. So I'd like to see more articles like the Tcl one that aren't for absolute beginners but instead try to teach a bit of the art of some skill or explore some hidden corner of a powerful program. This is the knowledge that is hard to come by.
Keep up the good work,
You will be glad to know (if you missed it before) that the Tcl/Tk column is slated to be a bimonthly column, and issue 18 has another of his columns.
We will continue to try to find a mix of articles for readers at all skill levels from novice to expert. At this point there are a lot of powerful programs that aren't being used at all, and we have been working on a lot of articles to introduce readers to new programs that have not had the publicity they deserve. I'm hoping this will help produce the need for more advanced articles about the same programs later. This way, the more advanced articles have a chance for wider readership. And the correlary is that right now, most of the more advanced articles are on topics that have wide interest, like the Tcl/Tk column.
I understand there has been work on versions of Linux for less common computers, like Micro Channel Bus PCs and MACs. What is the status of these ports?
We are not aware of any active work on support for MCA. Support for some PowerMACs may be available at some point, but don't hold your breath.
We regularily cover active porting efforts in Linux Journal. Stay tuned...
Matt Welsh, author of Linuxdoc-SGML and Linux Installation and Getting Started, recently finished the first leg of his country-wide tour to promote his book Linux Installation and Getting Started. His first stop was in Seattle, where Linux Journal staff members Phil Hughes and Amy Simpson met him at the airport. After a whirlwind tour of the Seattle area (and an unsuccessful attempt at locating a geoduck, a large bivalve found in the waters around Seattle) and a dinner of sushi and sake, he was whisked away to a local bookstore for his first talk. About 70-80 people were on hand—including a large contingent of Microsoft employees—to hear Matt talk. The audience was technically adept, and very receptive to Linux, and Matt did an excellent job despite the fact that the space alotted for the talk was more suitable for half the number of people that showed up.
The first leg of his tour ran from August 14th through August 20th, with stops in Seattle, Denver, Kansas City, St. Loius, Dallas, College Station, and Austin. Highlights of his trip include receiving an honorary citizenship to the city of Austin, signed by the mayor, and signing the guestbook at his St. Loius bookstore right below Newt Gingrich, and right before Anne Rice. Matt reports that the tour went quite well, and says he now has a much greater appreciation for the time usually allotted for sleep.
Practical Task Scheduling Deployment

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
