builds.sr.ht status

This repository is the monorepo for my personal tools and infrastructure. Everything in here is built using Nix with an automatic attribute-set layout that mirrors the filesystem layout of the repository (this might feel familiar to users of Bazel).

This repository used to be hosted on GitHub, but for a variety of reasons I have decided to take over the management of personal infrastructure - of which this repository is a core component.

If you've ended up here and have no idea who I am, feel free to follow me on Twitter.



  • tools/emacs contains my personal Emacs configuration (packages & config)
  • fun/aoc2019 contains solutions for a handful of Advent of Code 2019 challenges, before I ran out of interest
  • tools/blog_cli contains my tool for writing new blog posts and storing them in the DNS zone
  • tools/cheddar contains a source code and Markdown rendering tool that is integrated with my cgit instance to render files in various views
  • ops/kms_pass.nix is a tiny tool that emulates the user-interface of pass, but actually uses Google Cloud KMS for secret decryption
  • ops/kontemplate contains my Kubernetes resource templating tool (with which the services in this repository are deployed!)
  • ops/besadii contains a tool that runs as the git post-receive-hook on my git server to trigger builds on sourcehut.
  • third_party/nix contains my fork of the Nix package manager

Packages / Libraries

  • nix/buildGo implements a Nix library that can build Go software in the style of Bazel's rules_go. Go programs in this repository are built using this library.
  • nix/buildLisp implements a Nix library that can build Common Lisp software. Currently only SBCL is supported. Lisp programs in this repository are built using this library.
  • tools/emacs-pkgs contains various Emacs libraries that my Emacs setup uses, for example:
    • dottime.el provides dottime in the Emacs modeline
    • nix-util.el provides editing utilities for Nix files
    • term-switcher.el is an ivy-function for switching between vterm buffers
  • net/alcoholic_jwt contains an easy-to-use JWT-validation library for Rust
  • net/crimp contains a high-level HTTP client using cURL for Rust


Services in this repository are deployed on a Google Kubernetes Engine cluster using Nixery.

  • web/blog and web/homepage contain my blog and website setup (serving at tazj.in)
  • web/cgit-taz contains a slightly patched version of cgit that serves my git web interface at git.tazj.in
  • ops/journaldriver contains a small Rust daemon that can forward logs from journald to Stackdriver Logging


Presentations I've given in the past are in the presentations folder, these cover a variety of topics and some of them have links to recordings.

There's a few fun things in the fun/ folder, often with context given in the README. Check out my list of the best tools for example.
