Letters to the Editor
I'm glad to extend my subscription because Linux Journal is a very nice Linux-related magazine providing me with the global perspective of the Linux world which cannot be easily obtained by searching the Web, Usenet, and the like. I am always grateful for your efforts and hope LJ will continue to help me as it did in the past year of my subscription.Sohn, Jung-woo Aerospace Engineering Department Seoul National University, Korea. firstname.lastname@example.org
First, I would like to thank everyone at SSC for publishing Linux Journal. I eagerly wait for it to arrive at my door each month. I have been using Linux for a few years now and currently develope applications and utilities for Linux using Motif and, more recently, Java.
The concern I have for Linux is the ever-growing use of Java as a programming language of choice. I am not saying using Java to deploy applications on Linux is a bad thing, and I am not putting down the Java programming language (I use it regularly, and enjoy it). It just takes away some of the developer support for Linux-specific applications, which Linux needs. If applications are written in Java and run on Linux or any other operating system for that matter are we just turning our beloved operating systems into another Sun JavaStation or Oracle NC? Running Java-based applications on Linux is fine, but is Linux then losing the free and commercial application base that it needs to bring Linux to the next step? The next step being broad-based commercial Linux applications, that could be purchased at your local computer store or out of a general PC magazine. As many of us know, having a high number of applications available for an operating system attracts more people to it.
On the other hand, Linux has been a Java trail-blazer. Linux can incorporate Java binary support into its kernel. Creating applications in Java has its upside—applications which have been developed on a Microsoft platform can be easily run on the Linux operating system. Because of this, Linux could become a major platform in small- and medium-sized businesses that need both a rock solid operating system to run their operation and to be able to run all of the big name brand software. The Java language could actually increase the Linux-installed base around the world. If users of other operating systems become tired of software upgrade costs, downloading bug fixes and paying huge per minute costs to telephone support companies, maybe Linux will become the logical decision.

The history of personal computers seems to have many examples of systems clutched too tightly by their creators, missing out on opportunities to broaden appeal and usage. Making Linux Java-capable does not change the essential nature of Linux: free and open.
In my article on multithreaded programming [“What is Multi-Threading?”, Issue 34], I completely failed to mention where to obtain the library I make use of in the programs that go with the article. The library I use came from http://pauillac.inria.fr/~xleroy/linuxthreads and is very good, and less than 100K to download. Cheers, Martin McCarthy firstname.lastname@example.org
I just received my first issue of Linux Journal in the mail today. I must say that it is refreshing to know that there is a journal dedicated to Linux.
I live and play in Biloxi, Mississippi, an area not often thought of in positive, humanistic ways. But time and imported people have brought this area from gloom to glimmer. Technology has finally arrived in the deep south, sparked from casual conversations on a campus computer system, to a full blown ISP using Linux, of course. My Linux box is connected to the Internet via their service. Okay, so we have technology here, and we have people to utilize it. I know there is a small and quiet group of people out there who use Linux also. The gist of this letter is I would like to form a Linux users' group here, so the quiet group can join together and spread the wealth of knowledge out there with each other. For only by becoming a community of friends and associates, can we continue to grow and nurture our Love for Linux.Thank You Ted F. Fox email@example.com
This is a good opportunity to mention GLUE—Groups of Linux Users Everywhere. SSC, publishers of Linux Journal have established GLUE to give users groups visibility, special deals on SSC products, and other services to help groups grow. See the home page (http://www.ssc.com/glue/) for details.
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
