Nix seems perfect for developers - until I try to use it...

Want to use Nix for development but you're not sure how? Concerned about the fluidity of nixpkgs channels or not being able to easily install arbitrary package versions?

When I first heard about Nix it seemed like the perfect tool for a developer. When I tried to actually use it for developing and deploying web apps, though, the pieces just didn't seem to add up.

HTMLCollection.prototype.map = function(f) {
  var result = [];
  for (var i = 0; i < this.length; i = i + 1) {
    el = elements[i];

  };
  return result;

User env setup

Setup your user environment just the way you want with Nix.

1. Add packageOverrides to the attrset returned by your ${HOME}/.nixpkgs/config.nix (see my example above).

2. Then with one command you can setup your whole environment: nix-env -i desktop-mbbx6spp.

Then all you need is a simple ~/.bash_profile script like so:

Rust/Haskell: Higher-Kinded Types (HKT)

A higher kinded type is a concept that reifies a type constructor as an actual type.

A type constructor can be thought of in these analogies:

• like a function in the type universe
• as a type with a "hole" in it

Setup NixOS (Virtualized + Haskell + Gnome3 + XMonad)

Before you get started

This is pretty out of date now... you may want to look elsewhere

Newer guides than mine (mine is a bit dated and has a lot of rough edges):

• NixOS on MacBook Pro

Have you looked at these?
