This is my site for fun and work. I am Sander, a software architect.

Centrical is my playground. Blogs, news and resources are updated regularly.

My articles are published on Infoworld, AutomatiseringsGids and Emerce, too.

I gather worldwide news, whether it is about e-commerce or service oriented architectures.

My resume, the Web Unified Process and the general conditions are offered in several formats.

Some more information about me is shown here, like a resume, professional history and more.

Things I do are audits, architecture design and strategic advice.

Read the cases of customers like Akzo Nobel, Sanoma Publishers and VNU.

Stuff that happens to me sometimes inspires me to write. It may be nonsense, though.

WUP (Web Unified Process) is a lightweight and agile development method for web projects.

This where I keep technical posts that might come in handy.

Customizing Sharepoint

It's a pain to customize Sharepoint Portal Server's design. There is a lot to be found all around the web, though. I assembled a summary.

Barely good enough

The simple definition of an agile model? It's just barely good enough. Similarly, a document is agile when it's just barely good enough. Although traditionalists may balk at this definition, agile models (and similarly agile documents) are the most effective. If a model is not yet good enough, you clearly have more work to do. If a model is more than good enough, you've invested too much time in creating it, and therefore you've wasted your stakeholder's money. When a model, or a document, is just barely good enough it's most effective.

Scott Ambler (Agile Modeling) explains, in the Software Development Magazine newsletter from december 2004.

Trust first in XML security

"Trust then verify" was Ronald Reagan's maxim for international arms control. A similar maxim can be applied to security architectures in cross-firewall XML projects: "Trust then validate".

Let's just hope for the new Gorbatsjov, shall we?

Sun and Microsoft...

"Taking an intentionally cautious tone, Microsoft and Sun Microsystems executives said Wednesday that the first eight months of their 10-year partnership have yielded small, but significant progress."

SOAP performance

W3C announced the advancement of three technical reports to Proposed Recommendations offering an optimal way to transfer binary data like images in Web services messages. Produced by the XML Protocol Working Group, SOAP Version 1.2 is a lightweight protocol for exchanging structured information in a decentralized, distributed environment such as the Web.

Using an XML Schema datatype, XML-binary Optimized Packaging (XOP) allows efficient serialization of XML element content.
Using a XOP-based selective encoding, the SOAP Message Transmission Optimization Mechanism optimizes hop-by-hop exchanges between SOAP nodes.
The Resource Representation SOAP Header Block allows applications to carry a representation of a resource in a SOAP message.
