sterni 1027e21eee feat(sterni/blipqn): interact with a flipdot display from BQN 
The idea of this “library” is to do the least. The most natural way to
represent the image to render on a flipdot image is a two dimensional
array of booleans. This something BQN is very well equipped for, i.e. it
has primitives that are designed to deal with this type of data
structure. The only thing we have to do is to take care of sending such
arrays to the flipdot display via the μCCC's un(der)documented UDP
protocol.

Compact implements the conversion from a boolean array to a bitmap that
only uses 1 bit per pixel. All socket code is written in C and invoked
via •FFI. Currently, every time a bitmap is sent to a display, the
target host has to be resolved again. This should be fixed in the
future.

Build status

This repository is the monorepo for the community around The Virus Lounge, containing our personal tools and infrastructure. Everything in here is built using Nix.

A large portion of the software here is very self-referential, meaning that it exists to sustain the operation of the repository. This is the case because we partially see this as an experiment in tooling for monorepos.

Highlights

Services

  • Source code can be viewed primarily via cgit-pink on code.tvl.fyi, with code search being available through Livegrep on grep.tvl.fyi.

    The repository can be cloned using git from https://cl.tvl.fyi/depot.

  • All code in the depot, with the exception of code that is checked in to individual //users folders, needs to be reviewed. We use Gerrit on cl.tvl.fyi for this.

  • Issues are tracked via our own issue tracker on b.tvl.fyi. Its source code lives at //web/panettone/.

  • Smaller todo-list entries which do not warrant a separate issue are listed at todo.tvl.fyi.

  • We use Buildkite for CI. Recent builds are listed on tvl.fyi/builds and pipelines are configured dynamically via //ops/pipelines.

  • A search service that makes TVL services available via textual shortcuts is available: atward

All services that we host are deployed on NixOS machines that we manage. Their configuration is tracked in //ops/{modules,machines}.

Nix

  • //nix/readTree contains the Nix code which automatically registers projects in our Nix attribute hierarchy based on their in-tree location
  • //tools/nixery contains the source code of Nixery, a container registry that can build images ad-hoc from Nix packages
  • //nix/yants contains Yet Another Nix Type System, which we use for a variety of things throughout the repository
  • //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.
  • //web/blog and //web/atom-feed: A Nix-based static site generator which generates the web page and Atom feed for tazj.in (//users/tazjin/homepage) and tvl.fyi (//web/tvl)
  • //web/bubblegum contains a CGI-based web framework written in Nix.
  • //nix/nint: A shebang-compatible interpreter wrapper for Nix.
  • //tvix contains initial work towards a modular architecture for Nix.

We have a variety of other tools and libraries in the //nix folder which may be of interest.

Packages / Libraries

    • dottime.el provides dottime in the Emacs modeline
