How to: make Python dependencies installed via pip work on NixOS

The issue

You are using NixOS
You start working on a Python project
You manage the dependencies in a classic Python virtual environment using pip or poetry

You won't be able to import some of those libraries.

Create a lazy /nix/store filesystem using nixfs.py

Grab static nix from https://hydra.nixos.org/build/170454219/download/1/nix and place in the same dir as py script
Install fusepy (on nix: nix-shell -p python3Packages.fusepy)
Ensure your /etc/fuse.conf contains user_allow_other
Create workdirs: mkdir -p $(pwd)/{fakenix,workdir} && mkdir -p $(pwd)/fakenix/nix/store
Mount our fs: python nixfs.py $(pwd)/fakenix $(pwd)/workdir
Run some container image with workdir mounted: docker run -v $(pwd)/workdir/nix:/nix ubuntu:latest
Try running some command, for example: /nix/store/pqpa3glx3iqd0cavslmr0lfkzgq1iias-cowsay-3.03+dfsg2/bin/cowsay thefuck?

Random, unique Wallpaper for every tag in awesome wm

Awesome version >= 3.5

About

This is a way to get a random and unique wallpaper for every tag (or rather the last selected tab, since multiple tags can be selected) in the awesome window manager. The wallpapers are selected randomly from a provided path (which should only contain suitable pictures) and the algorithm guarantees a unique wallpaper for every tag.

Where to place

In the config file for awesome wm, which should be located at
