Last year, Linux use in the business community jumped by 10%. For this sort of growth to continue, more programs need to be written which directly target this community and the consumer in general. Computer stores are stocking Linux distributions. To promote the sale of these distributions to their customers, applications of interest to the consumer must be available. Accounting programs for the small as well as the large business, financial programs for the individual, educational tools, games and more games. These are the types of programs people want and are therefore the types that must be supplied.
Many projects to bring this type of application to Linux exist. Pick your favorite (http://www.linuxresources.com/apps/projects.html) and help out, or start one that is missing. Get active.
The place to start for programming information is, of course, Linux Journal. This month, in order to support the quest for applications, applications and more applications, we feature programming tutorials and tools. Programming has become an annual focus for Linux Journal because of its popularity with our readers. Our writers like it too, sending us more articles dealing with programming issues than any other topic.
Last November, we interviewed Guido Van Rossum, creator of the Python scripting language; last month, we interviewed John Ousterhout, the wizard of Tcl/Tk; this month, we talk to Larry Wall, the guru of Perl. To hone your programming skills, you can study the complete programming cycle, learn about POSIX threads, write your own GUI using Java and learn all about that architecture called CORBA. To learn a bit more about memory management, take a look on-line at a review of three memory checkers and a description of the buffer-overflow hack and how to avoid it (see “Strictly On-line” in the Table of Contents and our web site at http://www.linuxjournal.com/issue61/).

Larry talks about the past, present and future of the Perl programming language and along the way tells us a bit about himself.by Marjorie Richardson
Build your own graphical user interface using Java for true cross-platform portability. Mr. Darwin talks about the Java Foundation Classes and AWT (a windowing toolkit).by Ian Darwin
C programmers get a look at the basics of POSIX thread programming through the eyes of an expert. Mr. Masney discusses the problem of variable access synchronization and how to solve it.by Brian Masney
How to get started writing programs for the Common Object Request Broker Architecture—a look at the strengths and weaknesses of this very popular architecture.

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
