Travelling # Currently on my way back from a series of conferences in the past three weeks in the IC from Schiphol. After three weeks of conferences, lots of new input and lots of interesting projects I learned about it is finally time to head back and put the stuff I have learned to good use.

As seems normal with open source conferences I got far more input on interesting projects than I can expect to ever get applied in on a daily basis.

Apache Mahout @ Lisbon Codebits # Second week of November I’ll spend a few days in Lisbon - never would have thought that I’d return so quickly when I visited this beautiful city this summer during vacation. I’ll be there for Codebits - thanks to Sapo for inviting me to be there.
Back in summer I learned only after I returned to Germany that there was someone form Portugal seeking to meet with other Apache people exactly when I was down there.

First steps with git # A few weeks ago I started to use git not only for tracking changes in my own private repository but also for Mahout development and for reviewing patches. My setup probably is a bit unusual, so I thought, I’d first describe that before diving deeper into the specifc steps.
Workflow to implement
With my development I wanted to follow Mahout trunk very closely, integrating and merging any changes as soon as I continue to work on the code.

Scientific debugging # Quite some years ago I ready Why programs fail - a systematic guide to debugging - a book written on the art of debugging programs written by Andreas Zeller (Prof. at University Saarbrücken, researcher working on Mining Software Archives, Automated Debugging, Mutation Testing and Mining Models and one of the authors of famous Data Display Debugger).
One aspect that I found particularly intriguing about the book was up to then known to me only from the book Zen and the Art of Motorcycle Maintenance: Scientific debugging as a way to find bugs in a piece of software in a structured way with methods usually known from the scientific method.
