Prologue

I wrote this answer on stackexchange, here: https://stackoverflow.com/posts/12597919/

It was wrongly deleted for containing "proprietary information" years later. I think that's bullshit so I am posting it here. Come at me.

The Question

Amazon is a SOA system with 100s of services (or so says Amazon Chief Technology Officer Werner Vogels). How do they handle build and release?

In order to upgrade Haskell stack tool on NixOS without enabling nixos-unstable for all packages it is possible to install just one single package from unstable channel like following:

nix-env -f https://github.com/NixOS/nixpkgs-channels/archive/nixos-unstable.tar.gz -iA stack

If it happens that it is still older version, try unstable-small channel instead which gets updated more often:

nix-env -f https://github.com/NixOS/nixpkgs-channels/archive/nixos-unstable-small.tar.gz -iA stack

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:

maxim

#!/usr/bin/env bash
#
# gh-dl-release! It works!
# 
# This script downloads an asset from latest or specific Github release of a
# private repo. Feel free to extract more of the variables into command line
# parameters.
