Part our team was taking part in the Quality Excites conference last Saturday in Gliwice, Poland. They came and told the rest of the group that we need to be more careful how we program because we, as software developers, are more and more responsible for the air pollution. Wait what? Yes, we need to write more efficient code that uses fewer resources in order to reduce our carbon footprint. We have never looked on the efficiency of our code from this perspective. But it is an interesting angle. We will continue to produce efficient code as we did in the past. At least in that way we will try give back to the planet, what we are taking when we run the air conditioning during the summer heat we have now in Opole.
