+Woke up full of motivation to go to the office. Asked my honey if it's okay to join her by train "is there enough time left?", "yeah" she replied. Then when I come downstairs and she asks me if I can be fast, I tell her maybe it's better you go then bc i worry I will not be able to. Right away she storms off mad and angry... My motivation gone, so I'll work from home..

-Annotate tasks that are critical with the critical tag, `task <ID> annotate +critical` or `task add +critical blaat`

-Nix flakes are source trees containing a file `flake.nix` at their root. The file `flake.nix` provides a standardized way to provide [[Zettelkast/Index/Nix]] artifacts. It's like a package manager for [[Zettelkast/Index/Nix]]. A flake can be dependent on other Flakes and it's possible to pin dependencies to exact revisions by using a `flake.lock` file.
-
-Nix flake evaluation is hermetic, meaning that it produces the same result wherever it's built.k
-
-The feature can be enabled in `~/.config/nix/nix.conf`:
-
-```
-experimental-features = nix-command flakes
-```
-
-To initialize in a repo: `nix flake init`.
-
-In flakes dependencies have to be specified explicitly and MUST be locked to specific versions therefore it's no longer allowed to use the nixpkgs found in `NIX_PATH` by referencing it like `<nixpkgs>`.
-
-Output of a Flake is an arbitrary [[Zettelkast/Index/Nix]] value such as a package, [[NixOS]] module or library function.
-Commands `nix build` and `nix shell` will build the output `packages.<system>.default` unless we specify another output, for example: `nix shell .#checks.aarch64-linux.build`.

-## Why take notes?
-By writing down notes we can relate information about a subject in a very personal way using our
-own experiences to relate them to.
-
-We can us our notes as inspiration to create. In a centralized note taking system it is possible
-to easily revisit notes and use them to inspire new ideas.
-
-Another effect of a centralized note system is that it is very easy to search through our notes
-and use them as reference material.

-I want to become better at taking notes consistently in the hope that I forget less important things and become better overall at managing knowledge.
-To try and create the habit I will open a new daily note in Obsidian at the start of the day and sit down at the end of the day to refine anything written down into a more permanent form like this one. I'm hoping that by doing this consistently I will more often write down ideas, information, etc. during the day, rather than forget about it.
-
-After refining the daily notes, I should commit and push changes to a remote git repo that is also regularly backed up so I keep all this knowledge safe.
-
-I'm not yet sure if and how I incorporate this into a "zettelkast", something I did start before but never really stuck. I will need to do more research into this, and note taking overall.

 I need to more consistently read man pages. Example is `man task` to see how taskwarrior works, after reading it today I found that it is actually quite easy.
 They often contain good information on how to use a certain tool.

-Woke up full of motivation to go to the office. Asked my honey if it's okay to join her by train "is there enough time left?", "yeah" she replied. Then when I come downstairs and she asks me if I can be fast, I tell her maybe it's better you go then bc i worry I will not be able to. Right away she storms off mad and angry... My motivation gone, so I'll work from home..

+# Language
+ `nix repl` to interactively evaluate Nix expressions. `:p` if output is not full.
+ `nix-instantiate --eval <file>.nix` to evaluate a Nix expression from a file. `--strict`.
+
+Nix is like JSON, but with functions. 
+Recursive attribute sets can reference values declared earlier in the same set. 
+```nix
+rec {
+  one = 1;
+  two = one + 1;
+}
+```
+ 
+A `let` binding is used to assign names to values just as attribute sets, they can then be used in expressions. Let bindings have a local scope.
+
+A `with` allows referencing attributes of attribute sets without referencing the set.
+# Flakes
+Nix flakes are source trees containing a file `flake.nix` at their root. The file `flake.nix` provides a standardized way to provide [[Zettelkast/Index/Nix]] artifacts. It's like a package manager for [[Zettelkast/Index/Nix]]. A flake can be dependent on other Flakes and it's possible to pin dependencies to exact revisions by using a `flake.lock` file.
+
+Nix flake evaluation is hermetic, meaning that it produces the same result wherever it's built.k
+
+The feature can be enabled in `~/.config/nix/nix.conf`:
+
+```
+experimental-features = nix-command flakes
+```
+
+To initialize in a repo: `nix flake init`.
+
+In flakes dependencies have to be specified explicitly and MUST be locked to specific versions therefore it's no longer allowed to use the nixpkgs found in `NIX_PATH` by referencing it like `<nixpkgs>`.
+
+Output of a Flake is an arbitrary [[Zettelkast/Index/Nix]] value such as a package, [[NixOS]] module or library function.
+Commands `nix build` and `nix shell` will build the output `packages.<system>.default` unless we specify another output, for example: `nix shell .#checks.aarch64-linux.build`.
+
+# Overlays
+[[TODO]]
+
+# Shell.nix
+Can be used to set up per dir environments, e.g using direnv to automatically activate them.
+## Python
+https://nixos.org/manual/nixpkgs/stable/#python

+## Why take notes?
+By writing down notes we can relate information about a subject in a very personal way using our own experiences to relate them to.
+
+We can us our notes as inspiration to create. In a centralized note taking system it is possible to easily revisit notes and use them to inspire new ideas.
+
+Another effect of a centralized note system is that it is very easy to search through our notes and use them as reference material.
+
+## How
+Using the para method; a method of note taking by Tiago Forte (Building a second brain)
+
+Projects: Anything that requires the completion of multiple tasks to reach a certain outcome.
+Areas: Something that you are responsible for for a longer period of your live.
+Resources: Notes about resources that you use to do anything, such as tools and programming languages for example.
+Archive: Notes that you feel are nog longer relevant to you. They might end up being useful in unexpected ways
+so don't throw away!

 With `rabbitmqctl list_queues` we can add columns to show. So instead of the default layout which shows messages in the Q after the name and is horrible we can specify stuff like: `rabbitmqctl list_queues messages consumers name`. There are more options to be found in `man rabbitmqctl`.
