BlueSky friends, need your opinion:

@juanlam.com challenged me to write a #newsletter. Questions I have:

✍️

- Suggestions for getting started?
- Balancing time and schedule?

πŸ“–

- What topics are interesting?
- How do you want to engage?

Some of my interests:

- Applied Category Theory
- Systems Engineering
- Philosophy of Science
- Geospatial Health Informatics
- Pandemic Science
- Population Dynamics & Modeling
- Christian Faith & Practice
- High Performance Computing

I tend to write hundreds of personal notes on these subjects.
