I'm just learning stuff for my own personal use. However, as I'm an older guy on the Autism spectrum, some of the stuff that I'm learning about is quite complex. I tend to use open source / free / libre tools that are meant for enterprise level solutions, in my everyday personal life.
As of 5-Nov-2021, I'm currently working on creating a new home server setup, using two 8GB Raspberry Pi 4 Model B devices to run a password manager, household management system, home theatre system, personal contact management, medical and health records, etc.
