The entire nixfmt project recently has been a big disappointment for me. nixpkgs-fmt would have been a good starting point, having a balance between enforcing rules and allowing some freedom. While nixfmt initially started with outdated ideas like 80 line length and ill fitted tries to enforce that. Adding new lines before long strings like URLs, sometimes nudging people to split them with a + which makes greping for them unnecessarily hard. They didged that which is good.

Sometimes I want a reproducibility nightmare in #NixOS : apply a set of changes but only when the derivativion is rebuilt anyway.

Replaced an unbound today with knot resolver daemon or kresd. Was super easy to port with #NixOS and also create two PRs along the way: updating it to 5.7.2 and adding the missing psl Lua package to nixpkgs and kresd.
Next step is to replace the second and last bind with knot.

What's that thing with --extra-experimental-features?

So I tried to follow some tutorial about flakes, but it seems these are extra-experimental still....

TIL: You can enter a a process' exact namespace with the following command to debug systemd hardening with ease:
nsenter --all --target $PID

Why did no one tell me this earlier!?

Eine Distanzierung auf dem Theaterplatz ist aus der vorbeifahrenden Straßenbahn nicht zu erkennen. Ganz im Gegenteil man steht in einer Menge mit den Verfassungsfeinden der Freien Sachsen und zeigt deren Fahne.

Aus dem Augenwinkel hab ich noch eine schwarze Fahne vermeintlich erkannt, aber ohne Logo. Man ahnt nichts gutes.

My #NixOS 23.12 upgrade story for all the servers and VMs I manage:

Let's start with the terrible. Grafana crashed because it is missed a directory when using provisioned dashboards. Fix is in https://github.com/NixOS/nixpkgs/pull/272564

Then I searched an hour for a faulty change I did two days ago where I didn't think about split Portunus LDAP server and applications and needed to move a mkIf.

That's two #MicroVM|s done. The next two just worked without any changes and nothing broke (so far?).

I stumbled upon the mesa shader cache bug again today https://github.com/NixOS/nixpkgs/issues/244742

After doing some research I found that Ubuntu is supposed to have a workaround for it https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/2020604

But I just can't find the actual code change they did. Neither launchpad nor their git process is doing me any favor in making it easier to find things.

Everything I manage in my free time is now on postgres 16. My upgrade script now also handles postgres extensions and jit. https://github.com/SuperSandro2000/nixos-modules/blob/master/modules/postgres.nix
Pretty damn easy with #NixOS

Today I enabled tcp fastopen in nginx together with deferred and backlog and either my imagination is fooling me or my nextcloud is really opening noticeable faster. I read in a paper that tcp fastopen alone can improve connection times by ~15% or so. I was a bit lazy to do proper testing but I take the result.

Today was a productive day and I finally finished some really long taking projects. I am now hosting my own Knot DNS server and finally migrated off Cloudflare. Their DNS servers still respond with old NS records even over a day after deleting the domain from their service. Other DNS server respond with the correct one by now. Let's see when that stops.
I also migrated some mail addresess off GSuite (Google workspace they are called now I think) which triggered that journey

People often tell me that the #NixOS doc is not that great but compared to the #Vault secrets operator from #HashiCorp it is fantastic. There are like no explanations of things, mostly API docs. https://developer.hashicorp.com/vault/docs/platform/k8s/vso

There is also a "tutorial" which mostly consists of copy pasting commands and in the end you have a small example that works but you didn't really learn something.

Or maybe someone needs to point my nose on the right things.

story of this afternoon:

• wifi being very flaky
• ran into ssh rate limits
• soft reseted the wrong server with production services on it
• updated the wrong ceph component

Upsi...
