Just before that year of not writing anything here, I mentioned that I have a new microsimulation platform, and it is called Vivarium. That is still true, and now it even has some documentation: https://vivarium.readthedocs.io/en/latest/
It has been the thing that kept me too busy to blog for the last year. But it did generate some aesthetically pleasing figures for test purposes, as well as some population health results of interest. More details to come.
