Learn different languages. A tool is good for problems it was designed to solve. Here is a list of programming languages i would recommend in addition to python.

• c
• elixir
• rust
• go This would give you different perspectives on how a problem can be solved. And stay far away from jacascript.

Tutorials are nice to get the mechanics of the language but you should not stick with them for a long time. Start doing your own projects as soon as you feel comfortable with the language.

Yeah it would but it would not route your traffic through internet if both devices can communicate with each other over LAN.

DNS have nothing to do with SSL. Tailscale provide routing. It does not change applications running on the server.

TS have some convenient features to set up SSL but you cannot choose the domain name freely. I bet you can purchase a domain which redirects to ts domain id you want.

Then you don’t need to inform the rest of the world about your domain. Just use the hostname of the server on your tailnet and it should work all the time
