+#+TITLE: Pluto standalone
+
+This is a nix derivation that wraps a version of julia with the packages
+(and their dependency closure) defined in ~Packages.toml~; currently
+this is just Pluto. It also provides a little julia script that will
+activate this packageset (called a "julia depot"), and then start a
+Pluto notebook server on port 9999. Note that it does so without setting
+up any kind of authenticaton, so don't expose that port!
+
+* TODOs
+- [ ] add more packages
+- [ ] more sensible auth
+- [ ] working precompilation; this would probably allow running this
+  without a writable julia depot
+
+* Steps to reproduce / update the julia-to-nix part of this:
+
+In general, it is enough to follow the readme of julia2nix, but since
+that has a bunch of unstated assumptions and weird failure modes, here's a rough outline of how to actually do it:
+ - using julia's package managing mode, make changes to ~Packages.toml~
+   and ~Manifest.toml~. Be sure to use the same version of julia that
+   will run on hainich (currently the ~julia_15~ package of
+   nixpkgs-unstable), as otherwise hashes may be different
+ - clone https://github.com/thomasjm/julia2nix somewhere
+ - run ~julia2nix~ to generate the nix derivations
+   + unfortunately, jula2nix assumes that nixpkgs-unstable is available
+     as ~<nixpkgs>~ from within nix; it may fail if you are on another
+     channel. In that case, there seems to be no better solution than grepping for occurences of "<nixpkgs>" in jula2nix and replacing
+     them with some other path that has the required version
+   + this will re-generate all the ~*.nix~ files in this directory, and
+     probably reset all options. The defaults are reasonably sensible,
+     but make sure to disable the ~precompile~ option in ~default.nix~
+     (see below for why)
+ - run ~nix-build --no-out-link~ to check if it worked and nix can
+   build the julia depot
+ - deploy hainich. Note that the derivation will only contain the
+   package sources, not a compiled version. Julia will compile packages
+   on startup (and cache them for subsequent runs), so after the deploy
+   it may take a minute or two to actually run Pluto
+
+* precompilation
+/In theory/, we should be able to precompile all the packages during
+nix-build, and then directly load them into julia and runtime.
+However, this currently fails, and even if precompiled packages are
+present in the depot built via nix, julia will refuse to use them and
+recompile them instead (in a second julia depot that is writable at
+runtime).
+
+There's an open issue on this at jula2nix:
+  https://github.com/thomasjm/julia2nix/issues/22

+   Usually refs are either tags (refs/tags/*) or branches (refs/heads/*)
+   Cloning branches will make the hash check fail when there is an update.
+   But not all patches we want can be accessed by tags.
+
+   The workaround is getting the last n commits so that it's likely that they
+   still contain the hash we want.
+
+   for now : increase depth iteratively (TODO)
+
+   real fix: ask git folks to add a
+   git fetch $HASH contained in $BRANCH
+   facility because checking that $HASH is contained in $BRANCH is less
+   expensive than fetching --depth $N.
+   Even if git folks implemented this feature soon it may take years until
