I have played the drums since I was 13 years old, and have been playing in church since 1986. See my page on drumming here

When I have the time, I study the fascinating science of room acoustics. This all started when we needed to build new audio control room at church. After some initial investigation, it became apparent that we would need to put a lot of careful thought into the design of the control room in order to obtain the correct acoustic environment. The results of my studies are some Excel spreadsheets that can be used to predict the basic acoustic properties of a rectilinear room, and predict the absorption curve of various designs of porous absorber.

I have just started learning a programming language called Erlang. This language was developed by Ericson in the mid eighties originally to run telephone exchanges; but since it is designed to handle massive levels of process concurrency, I think it will also become a very useful business language. Here's what I've learnt about Erlang so far.
