Today I read a blog by Martin Fowler, the author of the famous Refactoring: Improving the Design of Existing Code and other books. The blog explained why he declined the invitation to be part of the SEMAT (Software Engineering Method and Theory) initiative by Ivar Jacobson, Bertrand Meyer, and Richard Soley. Ivar Jacobson is known for his contribution to the UML, together with Grady Booch and James Rumbaugh. All of them worked for Rational Software, now part of IBM, which I was part of from year 2000 to 2005.
Martin added his rationale for his declining:
…From here I got the distinct impression that the central thrust of the initiative is to create a software meta-method-kernel – essentially a set of common process elements for software developments that you can rigorously compose into a method for your own project. Read more »

In my previous blog, I talked about the object model of the vSphere API. Many people like the UML diagram that illustrates how the managed objects are inherited from each other.
Following that blog, I will introduce the object model of the open source Java API that is built on top of the Web Services, as well as some key design decisions I made while designing the API.
The following UML diagram is extracted from the overall model but adds much more details with properties and methods. If you can understand this diagram, you can then easily understand all other managed object types. Read more »

I mentioned the vSphere API self paced lab at PEX in my previous blog. Not all the people who are interested in learning the API made it to PEX last month. A reader asked me when it can be online in his comment.
Here is the VI Java API part in the tutorial. We had the environment set up all together for you in the PEX lab including the Eclipse and all the related jar files. So it’s very easy to get started there. Without going to PEX, you need to do something extra by yourself. But that is not too hard at all. I promise it won’t take you much time at all. To get the basic one done, you probably need 5 to 30 minutes depending on your familiarity with Java.

When I start to use a new API/SDK, I always look for the object model diagram before digging into the API Reference. With that, I can have a good overview of the API, from the concepts to the structure. This can save a lot of time.
Unfortunately, we don’t find such a object model diagram in any official document. The following is the UML diagram from my book VMware VI and vSphere SDK. Read more »
