Why do so many applications perform so poorly? And what can be done to change that? Testing applications for performance and scalability has become an afterthought in the software development community. According to Forrester Research, nearly 85 percent of large companies (more than $1 billion in revenue) have reported incidents of significant application performance problems. Why is this is happening? How can we improve this state of affairs? The key is the adoption of a formal performance-testing methodology. This article presents our methodology, complete with prerequisites, testing phases, and formal capacity assessment. The focus here is on performance testing rather than functional testing. |

Let's take both a practical and theoretical look at three of today's most primitive data structures. Weren't algorithms and data structures and their relatives your favorite engineering-related courses? For many of us, probably not! These were typically the "right of passage" courses in most computer science and engineering programs. That is, once you passed these courses, you were officially part of the program.
Unfortunately, the theory surrounding these "primitive" data structures can be among the first topics to escape our minds. This article aims to refresh the minds of both the experienced practitioner and the fresh graduate about some of the theory behind the data structures that we frequently use. I'll also offer some examples of where such structures may be found in the real world. |

"Legacy" isn't a dirty word. Your System i applications still have a long life ahead of them. |

Have you ever toyed with the idea of using CGIDEV2 to generate XML documents? |

Documentation is a very necessary evil, and as systems become more complex, consistent documentation becomes even more important. |

Have you ever seen a project plan with "a miracle occurs here" in the middle? Extracting business rules is tough, but you can start with documentation. |

It's one thing to modify (or "refactor") your own code, but how do you modify code that was written by someone else? |
