I cheated a bit to skip implementing multi cycle instructions. The VM is
pretty much a normal tail recursive function, but working with scalars
in BQN is on brand-ish. Array programming helps again when drawing the

By taking advantage of filling (ironically) we can avoid creating a spec
in an ugly way. Additionally we transpose before parsing which doesn't
really make all that much of a difference, though.

I primarily use GitHub for most of these preexisting repositories,
but they should be properly replicated on edwin in case I want to
stop. Pushing the respective refs manually is cumbersome and error
prone, so let's automate it.
The repositories are basically chowned to git:git currently and
`git fetch <remote> 'refs/*:refs/*' --prune` is execute regularly
to update the repository. In the future I could contemplate doing
it the other way round – using edwin as upstream and using
`git push --mirror` to update the GitHub repositories.

This adds edwin, the machine running sterni.lv, as well as my
idiosyncratic deployment solution. It is based on instantiating the
system configuration locally (where you'd work on the configuration),
copying the derivation files to the remote machine where the system
derivation is realised and deployed. Unfortunately, the first step tends
to be quite slow (despite gzip compression), so this may not be the
definite way despite its advantages.

This adds the module I've been using for running my minecraft servers.
It is inspired by the declarative minecraft server module in nixpkgs,
but
* does not support a non-declarative mode.
* supports more than one server on the same machine.
* patches the fabric mod loader into the server.jar on startup.
* its stopping mechanism is more robust: It issues a `save-all` and
`stop` command over RCON and uses flock(1) for waiting on the
server's shutdown instead of relying on checking for the PID
via kill(1) in a loop.
It has some gaps in terms of features that I personally don't need, but
can be filled in over time.

This is an old project of mine, I have still deployed because a friend
was interested in using it (I think they never did though). The
repository can't be subtree-ed at the moment since it is AGPL and also
contains some personal information I would prefer not to check into such
a long-lived repository. Relicensing and subtree-ing it using a
semi-elaborate josh filter would be possible in the future, but I'm not
sure if it is worth it yet. This is probably good enough for now, the
project also very rarely breaks on channel updates.

cluttering the global one and having these sources in a gc root
permanently.

Upstream nixpkgs removed a lot of aliases this time, so we needed to do
the following transformations. It's a real shame that aliases only
really become discoverable easily when they are removed.
* runCommandNoCC -> runCommand
* gmailieer -> lieer
We also need to work around the fact that home-manager hasn't catched
on to this rename.
* mysql -> mariadb
* pkgconfig -> pkg-config
This also affects our Nix fork which needs to be bumped.
* prometheus_client -> prometheus-client
* rxvt_unicode -> rxvt-unicode-unwrapped
* nix-review -> nixpkgs-review
* oauth2_proxy -> oauth2-proxy
Additionally, some Go-related builders decided to drop support for
passing the sha256 hash in directly, so we need to use the generic hash
arguments.

SCLF is quite a big utility library (almost 3€ LOC) with limited
portability (CMUCL, SBCL and CLISP to an extent). Continuing to maintain
it is an unnecessary burden, as depot only uses a fraction of it which
is now inlined into the respective users (mime4cl and mblog).
In the future trimming down ex-sclf.lisp may make sense either by
refactoring the code that uses it or by moving interesting utilities
into e.g. klatre.
