Apache Con Europe 2009 - part 2 # Thursday morning started with an interesting talk on open source collaboration tools and how they can help resolving some collaboration overhead on commercial software projects. Four goals can be reached with the help of the right tools: Sharing the project vision, tracking the current status of the project, finding places to help the project and documenting the project history as well as the reasons for decisions along the way.

Apache Con Europe 2009 - part 1 # The past week members, committers and users of Apache software projects gathered in Amsterdam for another Apache Con EU

Monday was BarCamp day for me, the first BarCamp I ever attended. Unfortunately not all participants proposed talks. So some of the atmosphere of an unconference was missing.

Books I found particularly helpful # During the last few years I have quite a few books that one could easily file under the category “Hacking books”. Some of them were particularly interesting to me and have influenced the way I write code. The following list certainly is not complete at all - but it is a nice starting point.
Effective C++ - I have comparably little experience with C++ but this book really helped understand some of the particularities.

Basic statistics of a set of values # Just in order to find that when searching for it yet another time:
Problem: You have a set of values (for instance time it took to process various queries). You want a quick overview of how the values are distributed.
Solution: Store the values in a file separated by newline, read the file with R and output summary statistics.
R: times <- scan(“times”, list(0))

Scrum @ Home # Scrum has proven to be a suitable toolset for managing software projects: Large, unmanageable tasks are broken up into little pieces that can be easily estimated in terms of complexity or time necessary for implementation. During a fixed amount of time, several of these tasks are implemented. By looking back at previous iterations it is simple to predict exactly how many items can be expected to be ready after the next iteration.
