Manage Secrets in NixOS

Recently, I experimented with running NixOS on a DigitalOcean droplet (which I will probably write about in the future), and migrated some of my toy projects from App Platform. During the migration process, I realized that I would have to somehow handle the DB certificate, and other sensitive credentials. I can’t just hardcode these! One of the more popular projects for problems like this is agenix. Their README for how to use it was a bit confusing (for me) so hopefully this post will be of use to others....

Create Rust binaries, and Docker images with Nix

Introduction A few days ago, I released the abomination of a project called emojied (website, repo) to the world. It went great, I’m glad people found it funny.

Post cover saying the phrase 'packaging pre-built, static binaries with Nix flake'

Packaging Pre-built Binaries with Nix Flake

Here’s the scenario: You have a nix environment all set up with all the dependencies you need for working on your next awesome project. All but one. nixpkgs doesn’t have the version you want. Fortunately, there’s a static binary file on their GitHub page. So should you just manually download it every time you set your project up, or should you write a Nix package that builds it from source?...
