last year I had the stats generated during the hour before my talk
<samueldr>
but did have a complete dump of the PR/issues to work with, so no rate limiting

clever_android has joined #nixcon
<samueldr>
good job repeating the question!
<samueldr>
it is often forgotten for off-mic questions
<samueldr>
(lol)
<globin>
samueldr: if we can find a reliable way of exporting the data, we can actually auto generate the stats regularly and host them.. the problem currently is the python script not running in a stable way
<samueldr>
my ruby thing looked stable enough
<samueldr>
not sure if it still works
<globin>
and it needing >10G of ram
<samueldr>
last time it ran was now about over a year ago
<samueldr>
it restarted the export from where it stopped
<samueldr>
so after the first dump, it generally doesn't hit much rate limiting
<globin>
samueldr: does it fetch the PR details too? i.e. comment count etc.
<samueldr>
and it's economical in memory, its job is just to dump to an sqlite db
<samueldr>
yes
<samueldr>
I was working on it with the goal of being able to automate stuff with that
<samueldr>
it also has the diffs!
<samueldr>
the sqlite db, last year, ended up being about 2~3 GiB if I'm remembering right
<globin>
nice!
<samueldr>
I think my main issue was that I kinda got stuck at "now where and how do I run it scheduled?"
<globin>
if you're able to share feel free, I'd try and get my jupyter notebook hooked up to that
<globin>
I think we could handle that
<samueldr>
I did get (part of) your notebook going
<globin>
I had a VM running for that already at mayflower, but giving it ~10G of RAM wasn't sustainable :/
<samueldr>
I figure
<samueldr>
I should dust it off
<samueldr>
it also handled rate limits right, so at any time you can re-dump everything
<samueldr>
ah!
<samueldr>
there was one PR that 500'd at github, that really annoyed me

so if you're running nix-master or nix-flakes, you now need this in your nix.conf: experimental-features = nix-command flakes
<niksnut>
or pass --experimental-features="..." on the command line
<haslersn>
But the error comes already during the `nixos-rebuild`
<niksnut>
what nixpkgs branch? it may need commit 52e739cc58e909f783a8bd3294307e554e35eaee to fix nix.conf checking

catching up on the livestream now, wish i could be there
<hyperfekt>
i find the committers / year graph from the release talk very interesting, looks like growth has slowed down
<hyperfekt>
we should think about why that is and how we want to solve that
<haslersn>
So I got `nix flake` to work like so: 1. clone `nixpkgs-channels/nixos-unstable`. 2. in there, cherry-pick `52e739cc58e909f783a8bd3294307e554e35eaee`. 3. Use that clone as `nixpkgs` (for example by setting `NIX_PATH` accordingly). 4. run `nix --option experimental-features nix-command flake [...]`.
<martyet-mobile>
Thanks adisbladis
<hyperfekt>
i really don't think we've hit the theoretical limit of available committers for something like nixpkgs yet
<haslersn>
Are the “Nix Flakes” slides online?
<sphalerite>
hyperfekt: I don't think it's a problem.
<hyperfekt>
sphalerite: you think nixpkgs couldn't benefit from more workhours?
<haslersn>
If I have a repo with `flake.nix` that describes several NixOS machines, and I cloned that repo locally, how can I most easily deploy a remote machine using mentioned flake?
<NinjaTrappeur>
adisbladis, we cannot find the source of the hum
<NinjaTrappeur>
I'm wondering whether this is the microphone inherant static noise of a failed cable/connection
<NinjaTrappeur>
:/
<samueldr>
Could it be exacerbated by the volume being turned up to pick up the speaker?
<samueldr>
(audionoob pretty much)
<martyet-mobile>
mmmm anyone experienced invited in resolving this trouble of course :)

It may be because of too high volume, but it doesn't make sense, if Radek decreased that volume already
