“Pro-russia hacktivists” that’s a weird way to say “state sponsored hackers”. Also they are using open VNC and default passwords? Really? The parties responsible for that infrastructure should be ashamed.

That’s not what ‘keyless entry’ means. You still have to open your door, you just don’t need to press a button to unlock it first.

Something like that indeed.
Every active network connection, every process, every piece of hardware and others are in your file system.
Then there’s also the possibility for linking to a file and links take up no space, but can show up like files.
You can use a command like ‘stat’ to get more information about a file (or directory).

Something to realise when starting with Linux is that everything is a ‘file’. Sockets, processes, input, output etc. That’s very different from Windows and part of why scripting on Linux is so powerful. You can interact with anything.
So some directories are filled with things that aren’t necessarily files but look like it. Someone else posted a whole list, just realise that under those directories/paths shouldn’t be messed with unless you know what it’s for.
Generally when you’re getting used to Linux, /home/$user (aka ~) is where you put personal things. The rest is managed by OS and applications, don’t worry about it.
Edit: spelling

If you’re hosting websites and not applications, perhaps you can use SSGs like Hugo/Gatsby. You could deploy your site in a bucket and put cloudflare in front. They can also be used on your own server of course. If you are hosting applications and want to keep them on 4g, you could put a CDN (CloudFlare or …) in frint of it. That would cache all static resources and greatly improve response times.

Containers are bad hmmkay… cause… cause… they’re bad… hmmkay

Portainer + caddy + watchtower, this will give you the benefits of containers without the complexity of Kubernetes. As someone who professionally works with Kubernetes, I agree with what other people have said here: “only run it if you want to learn it for professional use”.

Portainer is a friendly UI for running containers. It supports docker compose as well. It helps with observability and ops.
Caddy is an easy proxy with automatic Let’s Encrypt support.
Watchtower will update and restart your containers if there’s an update.
