## 1. Bio / Persona
Software engineer.
## 2. Prior Nix experience
Just finished packaging a C project at work with help of colleagues, and tackled packaging a personal / school project previously. Running Nix on [Windows Subsystem for Linux (WSL)](https://docs.microsoft.com/en-us/windows/wsl/about).
## 3. Approaches to learning Nix
Started learning from [Nix Pills](https://nixos.org/guides/nix-pills/) (highlights [Chapter 6.](https://nixos.org/guides/nix-pills/our-first-derivation.html)), but found it too deep with too many details.
- [NixOS/nixos-homepage#855](https://github.com/NixOS/nixos-homepage/pull/855) move Nix Pills to the end of recommendation list, reword logline
## 4. Using Nix
The starting point of this session is googling for `package nix cpp`, and evaluating the search results:
- [C - NixOS Wiki](https://nixos.wiki/wiki/C)
- [Inria](https://www.inria.fr/en)’s [Nix tutorial](https://nix-tutorial.gitlabpages.inria.fr/nix-tutorial/) (4th result)
Clones the project, and tries to re-use the [example Nix file](https://nix-tutorial.gitlabpages.inria.fr/nix-tutorial/first-experiment.html#first-experiment-default-nix) as a template for a personal project, but not familiar with C development, and wondering why both `make` and `cmake` is needed.
1. Copies example file into own project.
2. Culls `buildInputs`
3. Stops for a second at `src` and changes it to `./.` (remembers this from [Nix Pills, Chapter 7.](https://nixos.org/guides/nix-pills/working-derivation.html)) (Doesn’t understand what `rev` is for in the example anyway - maybe has something to do with the URL?)
4. Removes `mv chord $out/bin`
5. Runs `nix-shell own-project.nix`, builds it, and it works
**Interviewer** : How would you make the project, and run it in your environment, outside of `nix-shell`?
**Participant** : Would build it somehow.
Tries `nix-build`, gets a CMake error, but not familiar enough with CMake and Nix to make adjustments.
- [NixOS/nix.dev#882](https://github.com/NixOS/nixos-homepage/pull/882) make nix.dev official
Session ends here.

I want to point out [Jon Ringer](https://www.youtube.com/user/elitespartan117j27)’s youtube channel. It helped me better than any documentation i have found on how to actually package things for nix, and how to use the different tooling.
It is disappointing that this resource is on a channel not directly affiliated with NixOS. Making it into a “you just have to know that exists” situation.

You may be pleased to see that there is a [nix.dev PR](https://github.com/NixOS/nix.dev/pull/324) soon to be merged which places the videos more visibly. While this is not yet the front-page presence many rightfully desire, we’re slowly getting there.
