An open letter to software engineers criticizing Neil Ferguson's epidemics simulation code
Dear software engineers,
Many of you were horrified at the sight of the C++ code that Neil Ferguson and his team wrote to simulate the spread of epidemics. I feel with you. The only reason why I am less horrified than you is that I have seen a lot of similar-looking code before. It is in fact quite common in scientific computing, in particular in research projects that have been running for many years. But like you, I don't have much trust in that code being a faithful and trustworthy implementation of the epidemiological models that it is supposed to implement, and I don't want to defend bad code in science.
Wanted: a hierarchically modular software architecture
In his 1962 classic "The Architecture of Complexity", Herbert Simon described the hierarchical structure found in many complex systems, both natural and human-made. But even though complexity is recognized as a major issue in software development today, the architecture described by Simon is not common in software, and in fact seems unsupported by today's software development and deployment tools.
