EUREKA ITEA software Cluster AGILE project make it possible for European manufacturers to develop high quality embedded software in markedly shorter times and at much lower costs than possible with traditional techniques. Applying the approach to 68 pilot case studies in industries from avionics and telecommunications to consumer electronics, the project demonstrated clearly that ‘agile’ methodology can lead to massive improvements in embedded software engineering. Suitable tooling was also demonstrated to simplify application of the agile approach. As a result, much more software development can be carried out cost effectively in Europe rather than being outsourced to Asia.

Virtualisatie is een betrekkelijk nieuw fenomeen in de IT-wereld. Iedereen praat er weliswaar over maar in de praktijk wordt het nog maar mondjesmaat toegepast. Vaak op kleine schaal, min of meer als proefproject. Toch is men ervan overtuigd dat virtualisatie een blijvertje is. Wat is de toegevoegde waarde van deze technologie, hoe ziet de toekomst van virtualisatie eruit en als men al een opvatting over dit fenomeen heeft, klopt die dan met de werkelijkheid?

Ten years after the ratification of the first ISO C++ standard, C++ is heading for no less than a revolution. C++0x, the new C++ standard due in 2009, brings a new spirit and new flesh into the software development world. Brace yourself for state-of-the-art design idioms, even better performance, and a plethora of new features such as multithreading, concepts, hash table, rvalue references, smarter smart pointers, and new algorithms. No doubt you’ll find a lot to like in C++0x!

Have you ever wondered where those “Business Value” numbers in the XP Game came from? Have you ever wondered what salespeople, product managers and onsite customers do? Then we have a game for you: The Business Value Game

In the game you play the roles of salespeople, developers and accountants to try and deliver features to customers so that your
company can make money. The current version takes about 90 minutes to play. We received lots of ideas to extend the game to 120 minutes.

Like the XP Game, the Business Value Game is licensed as Creative Commons, so you can use and remix it.

It is my privilege to congratulate CrossTalk on 20 years of publishing articles for and by the defense software community. Longevity in any field is not easy, but longevity in the fast-paced world of software is indeed a notable accomplishment. The occurring changes during the past 20 years are far too countless to mention, yet they have all contributed to the present state of defense software today. Likewise, those of us currently involved with CrossTalk stand on the shoulders of the authors, editors, sponsors, and publishers who went before us, all of whom significantly contributed in assisting CrossTalk in fulfilling its mission of informing readers of new industry trends, proven methodologies, cutting-edge technologies, innovative practices, and, of
course, lessons learned.

In this special 20th anniversary issue, Gerald M. Weinberg takes a bi-directional view of where defense software had been and where it is going in his article What Have 20 Years Accomplished and What Is Left to Accomplish in the Next 20 Years?, while Dr. Linda Ibrahim provides insightful thoughts about the progress of the industry as a whole in A Process Improvement Commentary.

Watts S. Humphrey cautions readers in his article, The Process Revolution, not to repeat mistakes and to build reliability and consistency into your processes by consistently recording and learning from history. In the same vein, Paul Kimmerly’s article, Heroes: Carrying a Double-Edged Sword, discusses the benefits and limitations of heroes in process improvement efforts.

You may have heard the saying the more things change the more they stay the same. Interestingly, Dr. Alistair Cockburn explores the merits of this platitude in a software sense by reviewing Agile practices in his article Good Old Advice, and focuses on Agile’s applicability in today’s world.

Conversely, Jamie Hohman and Dr. Hossein Saiedian provide guidance in their article, Wiki Customization to Resolve Management Issues in Distributed Software Projects. This article adds new dimensions to the dynamics of traditional project management and provides methods of easing the stresses brought on by trying to manage distributed projects.

Lastly, don’t miss Gary A. Petersen’s witty walk down CrossTalk’s memory lane in his article, CrossTalk: The Long and Winding Road, as he examines the maturity and growth of the magazine as it developed from a diminutively distributed black-and-white copy to its current form and shape.

Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees. Every year, countless hours and significant resources are lost because of poorly written code. But it doesn’t have to be that way.

Noted software expert Robert C. Martin presents a revolutionary paradigm with Clean Code: A Handbook of Agile Software Craftsmanship. Martin has teamed up with his colleagues from Object Mentor to distill their best agile practice of cleaning code “on the fly” into a book that will instill within you the values of a software craftsman and make you a better programmer—but only if you work at it.

What kind of work will you be doing? You’ll be reading code—lots of code. And you will be challenged to think about what’s right about that code, and what’s wrong with it. More importantly, you will be challenged to reassess your professional values and your commitment to your craft.

Clean Code is divided into three parts. The first describes the principles, patterns, and practices of writing clean code. The second part consists of several case studies of increasing complexity. Each case study is an exercise in cleaning up code—of transforming a code base that has some problems into one that is sound and efficient. The third part is the payoff: a single chapter containing a list of heuristics and “smells” gathered while creating the case studies. The result is a knowledge base that describes the way we think when we write, read, and clean code.

Hadoop is a framework for running applications on large clusters built of commodity hardware. The Hadoop framework transparently provides applications both reliability and data motion. Hadoop implements a computational paradigm named Map/Reduce, where the application is divided into many small fragments of work, each of which may be executed or reexecuted on any node in the cluster. In addition, it provides a distributed file system (HDFS) that stores data on the compute nodes, providing very high aggregate bandwidth across the cluster. Both Map/Reduce and the distributed file system are designed so that node failures are automatically handled by the framework.

Project Time Management is one of the nine knowledge areas of the Project Management Body of Knowledge (PMBOK). It deals with the definition of activities (what are we going to do), the sequencing of the activities (in what order are we going to do them), and the development and control of the schedule (when are we going to perform those activities).

Over the past couple of weeks I have been trying to find out what the main principles of time management are in the case of agile software development. I was able to distinguish 10 principles so far, and I will present them here for your convenience. With each principle I also include a reference to an online article that (as far as I can tell) nicely describes the ideas behind it.
