The end of the year is always the time to reflect on the past happenings. My friends in Japan often send a New Year's card with 12 pictures, each showing the significant event during the month. I am not sure something significant related to Enterprise Integration Patterns happened each month, but I think it's still nice to reflect a little bit on the history and current state of the patterns. After all, the patterns have matured from a draft paper to being adopted as the lingua franca for a number of open source messaging projects.  Read more »

I have been pretty quiet recently, but I finally have some results to show. The current issue of IEEE Internet Computing (May/June 2007) contains my guest column for "Toward Integration". Also, I authored one chapter in the upcoming book "SOA Expertenwissen" (in German).  Read more »

Two years ago you were not cool if you did not have a blog. Today you are not cool if you have not done a podcast. Of course I cannot allow myself to fall behind, so here is my podcast on layered applications:  Read more »
