DESCRIPTION:[Nix](https://nixos.org/) is a powerful build system and packag
 e manager that enables declarative builds and deployments. This talk is ab
 out a couple of Nix's key strengths and how traditional package managers l
 ike DNF can (or can't) evolve to achieve some of the things Nix does.\n\nI
 'll discuss three advantages of Nix:\n\n1. Determinism: Nix can set up ide
 ntical development/build/runtime environments anywhere\, so software runs 
 the same on developer workstations\, on the CI\, and in production.\n\n2. 
 Customizability: With Nix\, there's no separation between the package mana
 ger and the build system\, so it's easy to patch dependencies to suit your
  needs\, for example to add a compiler flag or change the source repositor
 y out for a fork.\n\n3. Isolation: There's no issue installing multiple ve
 rsions of a program or library on the same system\, since Nix stores each 
 package in a separate filesystem tree.\n\nTraditional "imperative" package
  managers (APT\, DNF\, pacman) and even container tools (Docker\, Podman) 
 fall short of these goals (reproducible Docker builds are [not straightfor
 ward](https://medium.com/nttlabs/bit-for-bit-reproducible-builds-with-dock
 erfile-7cc2b9faed9f)!). But with a few changes\, we can get closer.\n\nThi
 s talk is intended for people who have experience packaging software and/o
 r building containers. Familiarity with Nix is great but is not required\;
  there will be plenty of Nix demonstrations!\n\nBonus: building Docker ima
 ges with Nix!
