Python programmers shouldn't get too smug. While many people agree that Python is designed in a way that makes it a highly readable language, there can still be problems with legacy, untested Python code too. Porting legacy Perl to Python can be a daunting task. In this article, learn some of the theory behind dealing with legacy code, including what not to do.

Here is a 4 part demo series to show you how to implement a solution stack (Rational Application Developer, WebSphere Application Server, and DB2 Express-C) on Ubuntu Linux, as well as how to integrate them in a Java application.

Learn how to download and install a Ubuntu image and then go through some basic shell commands to help you navigate through the Linux environment. This is part 1 of a 4 part demo series to show you how to implement a solution stack (Rational Application Developer, WebSphere Application Server, and DB2 Express-C) on Ubuntu Linux, as well as how to integrate them in a Java application.

Cloud computing and Infrastructure as a Service (IaaS) are well documented, but what's often not discussed is how to get a running Linux application into a cloud computing environment. Discover how to move an application into the cloud and take advantages of the features this setup has to offer.

This article humbley attempts to convince you that open source software is a solution for some subset of problems and that some of your problems most likely exist within that subset. See how open source is a flexible, usable approach to efficiency in your work environment.

The Linux® kernel includes a variety of APIs intended to help developers build simpler and more efficient driver and kernel applications. Two of the more common APIs that can be used for work deferral are the list management and timer APIs. Discover these APIs, and learn how to develop kernel applications with timers and lists.

For high-frequency threaded operations, the Linux® kernel provides tasklets and work queues. Tasklets and work queues implement deferrable functionality and replace the older bottom-half mechanism for drivers. This article explores the use of tasklets and work queues in the kernel and shows you how to build deferrable functions with these APIs.

The Linux® system call interface permits user-space applications to invoke functionality in the kernel, but what about invoking user-space applications from the kernel? Explore the usermode-helper API, and learn how to invoke user-space applications and manipulate their output.
