im very n00b about tech shit so i will ask 2 questions.

I want to self host some services for me and my first questions is: Any guide or book, or wtv, you recommend to understand self host world? I want to understand all things about it, but dont know where to start. And the guides for beginners i found on internet are very basic, just seems things like "do that, do this, and go" . I want to fully understand the world of self host. I want to understand firewalls, DyanmicDNS, MeshVPN; How to do self host; what not to do, what precautions, etc, etc.

The other question is about programming. I would love to know programming, but dont know where to start either. My focus is build android apps. Would like to learn programming to build apps for all world, but dont know how to do it and where to start. And i dont want make money with this, i just want to do this just for fun. Any advice? which language is better for a person who dont know nothing? which programs i need to install to start? Any book or tutorial recommendation ? im lost lol. thx

My first programming language was Java and if you're looking to build android apps you only really have 3 options, Java, Kotlin & Dart. Android is built on Java so if you want to learn how android works, I'd recommend Java or Kotlin.

As for learning to program, your best bet is to think of a project and then try to build it. You will inevitably hit a wall at some point and working out how to overcome it is the best way to learn programming IMO.

The classic first apps are "Hello world" and a Todo list. Hello world is just an app which says hello to you on startup, it's hard to make a simpler app. A Todo list app is a note taking app where notes are saved between sessions, and can be deleted or updated.
