Nix as OS X Package Manager
When I first heard about Docker, I thought it did what Nix does.<p>Then someone handed me a docker image saying, &quot;I got this working on my laptop, deploy this. Isn&#x27;t this great!&quot;.  I had no idea how they arrived at that configuration. If something happened to them or that image, I wouldn&#x27;t have known how to reproduce that &quot;working state&quot;.<p>So I am happy to see Nix &#x2F; Guix become popular. It is what I imagined package management to be.<p>Before that we just used rpm and deb packages. For all the hate they get, they are actually well thought out, tested, stable format. With {pre&#x2F;post}-{install&#x2F;uninstall} script support, dependency resolution and so on.<p>But Nix &#x2F; Guix is a qualitatively different things. Hope it becomes popular.
