In one of his recent blog-posts Martin Fowler explains, why he is not interested in participating in the Software Engineering Method and Theory initiative (SEMAT) by Jacobson, Meyer, and Soley. Now, this is not really big news, however if found the argument interesting. He refers to Alistair Cockburn saying: " [...] that since people are the central element in software development, and

I found a very interesting article on the MSDN Architecture Center illustrates a real life use case about scalable systems. Designing and building scalable systems is one of the major challenges of Software Engineers. A lot of best practices and patterns exist on the web illustrating the problem, but the specific design and the implementation differ in projects. This article tells a real life

When you learn a programming language you usually develop small applications to analyze the pros and cons of the language. Another important part is to check the offer of available libraries, frameworks and last but not least the tool support. Programming from scratch is the unusual way when you develop a software system. In Mike Taylers blog is a very interesting discussion about "Whatever

Just a quick Post: I (and DZone readers) found this link quite interesting. It shows technology trends and the interesting figures are not the absulute values but the technologies that have the fastest grow.

I am using Mercurial since about half a year pretty regularly and I am also (forced) to use GIT recently. And I must say, that I am not pleased with the GIT experience at all. An initial statement first, though: I am not arguing about features here; it is no doubt, that GIT is an extremely powerful and also reliable sourcecode management system. But the user experience is, in my opinion,

If you develop Client or Web applications providing a User Interface you end up with questions like: Which GUI do we provide Elements (Input fields, Buttons, etc.) should the GUI contain What is the structure of the GUI and many other questions Usually you have several workshops with the end users who work with the final software systems. Balsamiq mockups is a great tool to create mockup GUIs in

The main topic of the actual Eclipse Magazin is called Plugin Parade, where I published a short article about the new Mule IDE and Mule Data Integrator, two Plugins for Eclipse. The Mule IDE provides an integrated Mule server for Eclipse. Therefore the test of Mule environments in Eclipse is very comfortable and easy. As data transformation is a significant part in an ESB, a graphical support

Today I attended the session called "Cloud Computing ohne Buzzwords - und wie sieht die Zukunft aus" at the OOP 2010, provided and overview of Cloud Computing and their effects to present Software Architectures.

In "Interviews with Innovators" Jon Udell talked recently with Greg Wilson. Greg Wilson is well known for his "Software Carpentry" courses. These courses did not focus on computer science students but mainly on students from other scientific disciplines like Chemistry, Physics or generally engineering studies. His goal in the "carpentry" courses was, as I understand it, to teach scientists who

As some may have noticed, I migrated nearly all my projects in the last year from Subversion to Mercurial (and GIT). Step by step, as I am rather conservative with changing to new technologies, particularly when they are at the heart of the project. And changing the SCM is sort of a surgery on the open heart.However, after nearly a year of experience I must say, SCM was (for me) never easier and

Some of you might already have noticed, that we were not very active in blogging the last months. The reason is, that (most of us) were heavily involved in finishing our "Best Practice Software Engineering" book that will be available Feb/March 2010. The publisher is Spektrum Akademischer Verlag (Springer), the book is in German.It was a lot of work and required most of our publishing energy. I

Template engines are widely used in Web Frameworks, such as Struts, JSF and many other technologies. Apart from classical Web Framework, template engines can be very useful in integration projects. In an actual integration project that deals with a lot of XML data exchange, I discovered the Java Template Engine Library FreeMarker. This Open Source Library is a generic template engine in order to

The blog of Cedric Beust (author of TestNG and captured by Google) is always an interesting read.His last posting discusses the question if generic test features should be included into the language:http://beust.com/weblog/archives/000522.htmlHe mentioned an interesting D feature. Personally I think a tighter language integration is useful for small projects. Nevertheless it should be easy to

Since a few days it is official: The Subversion project has submitted to become an Apache project. It seems that the incubation phase will start soon. Now my question: Subversion is conceptually dead, so what difference does that make? Ok, let's discuss this a little more in detail:The thing is: most developers (even myself) meanwhile understand the concept of DSCM systems and all available

On August 13th, more than 50 other people, interested in open source software, attended the 8th Google Open Source Jam in Zurich, which is an informal (bar-camp like) meet-up at Zurich office (also available in other parts of the world) and a perfect opportunity to meet other open source developers as well as Google engineers in a relaxed atmosphere. As it is open to everyone, people held

I am using Mercurial a lot recently (and love it); I really do wonder, why I struggled so long with Subversion. When I first heard the GIT presentation from Linus Torvalds (which is, hm, very entertaining) the whole distributed SCM thing sounded very esotheric for me. However I decided to give it a try, also motivated by the great Chaosradio Express 130 Podcast (German). Yet, I decided to go with

It looks like we are living in a fantastic time concerning programming languages. Creating a new language has never been easier then before. With the two great platforms Java and .Net it's not extremely difficult any more to generate intermediate code from the language you are dreaming of. And even the pragmatic bookshelf has a book in writing on "language patterns" to cover this topic.Thus I

Following up a question I received via Twitter, and the fact, that a significant part of the developer-community is using Macs, I thought this might be a good opportunity to discuss some "UML Options" for the Mac.

If you develop applications, which consumes web services from other applications or integration platforms, debugging can often be very deflating. If you don't use the correct debugging tools, you don't see the generated SOAP messages which are delivered between the parties.A very useful tool is the Open Source SOAP monitoring tool from predic8. The tool does the same as the TCP monitor from Axis,

In the current issue of the Java Magazin I published a tutorial to develop loose coupled systems with Mule. The tutorial illustrates the usage of an Enterprise Service Bus in an airport domain, where different airport systems communicate with each other over the ESB. In the example I use a set of important Enterprise Integration Patterns and show how these patterns are implemented in Mule. Some
