I have a 10 year old laptop of very low specs. I had given a detailed description of the specs and made a post regarding the use to which it can be put, and more or less everyone pointed to self hosting.
Now, if the machine is powerful enough, why not put it to some productive use ??
And so l’m exploring an unknown territory.

I was one of the people pointing you to self hosting so I would start with Linux upskilling

Then I would look into learning how to use Docker, followed by how to make docker compose files.
