Strange start to my Monday where I spent ~2h debugging my hanging
NixOS. Strangely I'm not sure I made any changes to my configuration to trigger
this, and I was finding this hard to reproduce:
- graphical X sessions hung (once when opening Chrome)
- TTYs hung (during `nix-build` and `rebuild-system`)
Per kn's recommendations whenever a system is hanging, see if it's reachable
over the network (e.g. SSH). Since I didn't have my laptop, I downloaded Termius
on my iPhone, which I used to mosh into ava, which is a surprisingly nice UX.
I suspect my machine (with only 8GB of RAM) was OOMing, but I'm not
certain. Thanks to grfn I installed `earlyoom`. For more commentary, check-out
Profpatsch's blog post about this: https://profpatsch.de/notes/preventing-oom
What went well:
- Thankfully I installed a Matrix client on my iPhone last week, which allowed
me to troubleshoot with the #tvl folks
AIs:
- I'd like some instrumentation like Prometheus, Loki (`journald`, `dmesg`), so
that I can accumulate troubleshooting information that isn't destroyed when I
reboot my machine (which I did 1/2-dozen times today).
- Consider adding `git` metadata to `system.nixos.label` to get more useful
information in a GRUB/EFI context.
More unknowns:
- Why can't I switch back to EFI (from GRUB) for my bootloader?

Use nixos-unstable-small which fixes CVE-2018-25032
(out of bounds write while compressing).
* //users/grfn/xanthous:
- Supporting random-fu 0.3 requires considerable changes and patching
random-extras (https://github.com/aristidb/random-extras/pull/5).
For now we downgrade random-fu and its dependency rvar to 0.2.*,
forcing us to build xanthous with GHC 8.10.7, due to random-fu 0.2.*
not supporting that version.
Nix expressions for the downgraded packages are checked in to avoid
the potential need to compile Haskell at pipeline eval time.
- generic-arbitrary exposes a GenericArbitrary newtype now.
This means we no longer have to implement it in xanthous
downstream and patch generic-arbitrary to expose the
GArbitrary type class.
- Minor adjustments for lens 5.0:
Xanthous.Game.Memo: clear needs to use ASetter' instead of Lens'
Xanthous.Data.EntityMap: TraversableWithIndex no longer has an
itraversed function.
- Xanthous.Orphans: adjust for aeson's KeyMap, use KM.size explicitly
instead of relying on MonoTraversable's length
* //nix/buildLisp: the CCL issue has resurfaced, disabling the
implementation once again.
* //3p/arion: remove, as depot uses the nixpkgs package of it anyways.
* //users/wpcarro: accomodate GHC 9.0.1's stricter parsing of operators.
* //users/tazjin: disable rustfmt as it stopped respecting settings
* //3p/overlays: upgrade home-manager until fix for serivce generation
has landed upstream
* //users/grfn/system: remove rr override, as the pinned commit is part
of the 5.5.0 release shipped by nixpkgs.
