Porting an operating system to new hardware can be a fairly easy process, or a fairly difficult one, depending on the issues you encounter. This article details experience porting NetBSD on a new board to the TAMS 3011, already existing hardware. See all the articles in the series.

Take a grand tour of the Apache Geronimo 1.1 newly added features, and get expert tips on how to use them. This article gives you an overview of the architectural changes introduced in the latest Geronimo release, focusing on the new and innovative plug-in architecture. You'll also examine enhancements to the Web Console, including the memory utilization graph, thread pool statistics, the JMS resource wizard, and keystores.

In Part 1 of this series you learned about Developer Workbench concepts and basic tasks. In this article learn how the Eclipse-based Developer Workbench resources, perspectives, views, editors, and wizards assist you to work with stored procedures. DWB is based on Eclipse technology, which replaces the Swing-based DB2 V8 Development Center.

With so many Continuous Integration (CI) servers to choose from, it can be difficult to decide which one is right for you. In the second article of the series Automation for the people, development automation expert Paul Duvall explores a handful of open source CI servers, including Continuum, CruiseControl, and Luntbuild, using a consistent evaluation criteria and illustrative examples.

Network File System (NFS) has been part of the world of free operating systems and proprietary UNIX flavors since the mid-1980s. But not all administrators know how it works or why there have been new releases. It is important to know about NFS simply because the system is vital for seamless access across UNIX networks. Learn how the latest release of NFS, NFSv4, has addressed many criticisms, particularly with regard to security problems, that became apparent in versions 2 and 3.

A pervasive misconception common today is that simply designing your file format around XML somehow makes it magically portable, extensible, and intelligible by other programs. Peter Seebach explains why using XML is only part of the story when you're designing an extensible file format.

Examine how to configure Secure Shell (SSH) on IBM System p and System x computers to run commands in parallel in a cluster without being prompted for a password. This will allow you to perform activities more easily and quickly, and gives you flexibility to perform activities in parallel on more machines.

In this second installment of the GNU Linear Programming Kit (GLPK), a diet problem shows you how to formulate a simple multi-variable and declare bidimensional parameters. A post office resource allocation problem then introduces MathProg expressions and integer-only decision variables.

In this article, I cast before you another five pearls of wisdom, focusing more on smaller companies without the overhead, or support structures, of a larger organization. For more less commonly states yet invaluable hints check out the previous installment in the Don't let these disasters happen to you series, targeted at embedded engineers in larger corporations.

Robot simulators can greatly simplify the job of building physical robots. Through simulators, you can test ideas and strategies before putting them into hardware. Luckily, the Linux and open source communities have several options that save you time and money, and can even support direct linkage to hardware platforms. This article introduces you to some of the open source robotics toolkits for Linux, demonstrates their capabilities, and helps you decide which is best for you.

NetBSD runs on more hardware platforms than any other UNIX derivative due to smart design decisions and a commitment to portable code. For porting an operating system to a proprietary embedded system or looking for stability and compatibility across hardware platforms in the lab, the smart choice is NetBSD. In addition, learn why its open license is a compelling alternative to Linux and the GNU Public License.

When it's time to pass around sensitive or private data in Web application development, you soon realize the need for encrypting that data. This is where Secure Sockets Layer (SSL) to protect your applications becomes very useful. In this tutorial get help navigating the tricky waters of application-to-application encryption, and learn how to configure Apache Geronimo 1.1 and 1.0 with SSL and test the SSL with the Geronimo Hello World application.

The most common input/output model used in Linux is synchronous I/O. After a request is made in this model, the application blocks until the request is satisfied; the calling application requires no CPU while it awaits the completion of the I/O request. But in some cases there's a need to overlap an I/O request with other processing. The POSIX asynchronous I/O (AIO) API provides this capability. In this article, get an overview of the API and see how to use it.

This article addresses the most commonly encountered scenarios and errors while porting Fortran or any UNIX or Linux-based applications on different systems. Discover how to port Fortran-based High Performance Computing applications, such as computational fluid dynamic (CFD) modeling, weather modeling, and linear algebra packages, using IBM XL compilers and gnu compilers on large clusters.

Add a Web-based user interface to a previously developed multimedia client in this episode of the Multifunction multimedia machine series. Author Lewin Edwards looks both at user-interface and back-end design issues, and shows how local browser functionality is an interesting alternative to requiring a remote browser.

Test, profile, and monitor your applications with an advanced, extensible platform in this installment of the "Eclipse Test and Performance Tools Platform" tutorial series. Learn how to use Eclipse TPTP testing features to measure the response time of your Web application. Then, discover how to create and manage improved JUnit tests and create computer-directed manual testing.

In this final installment on testing of the three part series, Brian Goetz examines another technique for smoking out bugs that violate design rules: aspects. The first two installments in this series, Part 1 covering testing in integrated frameworks and Part 2 on testing with leverage, show how static analysis tools like FindBugs can provide greater leverage in managing software quality by focusing on entire categories of bugs rather than on specific bug instances.

This series chronicles the creation of the ultimate mashup, an application that not only stores data from different mashups but uses semantic technology to enable users to create their own mashups by swapping services, or even by picking and choosing data. In this part, Nicholas Chase introduces the concept of mashups, shows you how they work and how to build a simple version of one. Mashups use Java programming and a combination of servlets, JSP, software from the open source Jena project, and DB2's new native XML capabilities.

The ability to install and create plug-ins is one of the most anticipated new features in the Apache Geronimo 1.1 release. This article introduces you to Geronimo plug-ins and shows you how to find them, install them, and create them yourself. Plug-ins open a new world of instant upgrades for Geronimo users. You can now download new applications and services and have them running on your Geronimo server within minutes.

Learn the method for automating updates to a library of XML files so that they all conform to an updated XML schema in this two part tutorial series. In Part 1, you learn the steps in the entire process, and then create an XSLT stylesheet to update the XML files. In Part 2, you learn to install, configure, and run Ant and Java SE to iteratively transform each of your XML files based on the updates specified in your XSLT stylesheet.
