Gabriel Arazas edc686c25c Update wiki on various topics

This update is too large, I made too many notes on stuff. Nonetheless,
it is very nice to see progress. I've made note revisions on the
following topics:

- Learning
- Writing
- Various Linux-related stuff

I've yet to start learning illustration but I'll be starting tomorrow
for an update how do I keep in mind with those writings. There are still
a lot of things to be processed from the backlog with yet more notes on
learning but I keep having those perspectives whenever I practice so
ehhh... Better have those than nothing?

Furthermore, I've also updated the timestamp format. It is pretty simple
to update all of the notes with a couple of `sed` calls.

Aaaand, I've also changed the way how the assets stored with the folders
only leaving it up for the generated files instead of enforcing it on
every note. I create more visual aids and managing them is a pain for
each note. This restructuring frees me of that burden.

Nix derivations

Derivations are recipes for the Nix build daemon how to build the package. At a glance, this is the equivalent to manifests from Flatpak packages or Guix packages.

The following code block shows what a derivation looks like.

nix show-derivation nixpkgs.hello

{
  "/nix/store/7xcq1j6kxry9p5scmgccifqp1m57ha17-hello-2.10.drv": {

      "version": "2.10"
    }
  }
}

While we can create derivations with the Nix language, it is unnecessary and verbose if we use nixpkgs. nixpkgs has made the process easier with their standard library.

stdenv.mkDerivation
nixpkgs also comes with several convenient functions/environments for several programming languages and frameworks including Python, Rust, Go, and Nim
it also includes environments for common setups such as for clang compiler
