@sporeray:matrix.orgRobbie Buxton And if you can get an end to end training run going 15:07:35
@rudyshoes:matrix.orgAtix i wanna contribute to nix/nixos 15:07:49
@sporeray:matrix.orgRobbie BuxtonThat would be a good start!15:07:55

i wanna contribute to nix/nixos
Sure but you need to start somewhere to have things to contribute!
15:08:11
@sporeray:matrix.orgRobbie Buxton I think most of us here are working on related things and then contributing to nix/nixos along the way 15:09:03
@rudyshoes:matrix.orgAtixthank you!15:09:07
@sporeray:matrix.orgRobbie Buxton I.e packaging new things we want to try 15:09:15
@sporeray:matrix.orgRobbie Buxton Or fixing bugs we come across 15:09:25
@sporeray:matrix.orgRobbie Buxton So I’d come up with a project idea and then try and do it in nix/with nixos 15:09:46
@sporeray:matrix.orgRobbie BuxtonI’m sure you’ll have plenty of opportunities to contribute if you do that!15:10:06
@ss:someonex.netSomeoneSerge (back on matrix)The other active channels are nixos rocm, and also maybe Matthew's nixified.ai (but I think it's more of a user group than a dev room). There's also an HPC and a Data Science channels under nixos-org, and Bionix, - but there's not much happening there I'm afraid15:10:37

@ss:someonex.netSomeoneSerge (back on matrix)I think I had run Sway on an nvidia machine for some time but ultimately rolled back to i3 (and now I only have access to headless nvidia)16:22:51
@ss:someonex.netSomeoneSerge (back on matrix)Basically, it was occasionally OK, but then you bump the kernel and it flickers again16:23:22
@ss:someonex.netSomeoneSerge (back on matrix) Had to keep the kernelPackages pinned most of the time too 16:23:37
@ss:someonex.netSomeoneSerge (back on matrix) I'm afraid even NixOS cannot fixes all of NVIDIA's problems 16:24:07
@ss:someonex.netSomeoneSerge (back on matrix) * I'm afraid even NixOS cannot fix all of NVIDIA's problems 16:24:14
@ss:someonex.netSomeoneSerge (back on matrix)Best if you have an integrated graphics to keep your display on...16:25:23
@justbrowsing:matrix.orgKevin Mittman (UTC-7)I use swaywm with --unsupported-gpu (though not on nixos)16:39:04

@adrian-gierakowski:matrix.orgadrian-gierakowskisorry if this has been discussed before, but looking at https://hydra.nix-community.org/jobset/nixpkgs/cuda-stable#tabs-evaluations the last Job I'm seeing was a week ago. I thought this jobset was following nixos-unstable-small (although now that I've checked, it's nixos-25.05-small)16:11:35

@adrian-gierakowski:matrix.orgadrian-gierakowski* sorry if this has been discussed before, but looking at https://hydra.nix-community.org/jobset/nixpkgs/cuda-stable#tabs-evaluations the last Job I'm seeing was a week ago. I thought this jobset was following nixos-unstable-small (although now that I've checked, it's nixos-25.05-small). Has something happened that stopped it from running? 16:12:19

@tpw_rules:matrix.orgtpw_ruleshey. i had previously sympathzied with samuela and like i said before had some of the same frustrations. i just edited my github comment to add "[CUDA] packages are universally complicated, fragile to package, and critical to daily operations. Nix being able to manage them is unbelievably helpful to those of us who work with them regularly, even if support is downgraded to only having an expectation of function on stable branches."03:29:14
