Focus: Programming
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. The application developed as an example uses the freely available OmniORB from Oracle-Olivetti Research.by J. Mark Shacklette and Jeff Illian
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.
Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?
