 This post is the first in a series on reverse engineering binary file formats using an array of tools,
 mainly to serve as insight into how to approach these kinds of challenges as they can be daunting.
 Part one focuses on the image format.

 Other users have tied their blog to the NixOS system-level configuration, like [this user](https://jeancharles.quillet.org/posts/2023-08-01-Deploying-a-static-website-with-nix.html). While I think this
 is a good solution, it has the issue of relying on root access for updating the site.
 To me, this feels excessive. I should be able to deploy my site from a lesser-privileged user.
