Where can I get some good courses/resources to improve my tech skills?
I've been toying with the idea of having a little hobby computer store for years and I've reached the point where I feel I have nothing to lose in trying it.
I don't intend to make it my main source of income but I'd like to have some sort of formal knowledge base to resort to, regardless I've been acting as the tech guy for several years for a lot of people.
Where can I find some good courses/resources, preferably online, to improve my knowledge base?
I'm a long time Linux user so I intend to use my hobby to make some noise about it.
Find a project and build a home lab.
Build it the hard way, maintain it and open services to your family.
Same ideas: ebook library like Kavita, or Plex server, or Ad Guard, or VPN for the times you're travelling, or NextCloud for your personal cloud drive, or folding@home if you're feeling charitable with your compute power.
Anything, the important thing is to get started.
Each project has different routes of installation, depending on what you wanna learn, make it happen through research and learning.
