 Alexandros Liarokapis | Oh okay interesting | 20:19:03 |
| 9 Nov 2025 |
| Alexandros Liarokapis | There is also the nix community cache | 00:24:17 |
| Alexandros Liarokapis | Does that have an actual allowance to redistribute or is it in a weird grey legal zone or similar | 00:24:43 |
 hexa (UTC+1) | grey zone | 00:35:22 |
| hexa (UTC+1) | the flox cache is weird, because it doesn't align with nixos channel bumps | 00:35:37 |
| hexa (UTC+1) | and doesn't provide builds for stable nixos | 00:35:57 |
 Robbie Buxton | Yeah it’s bit vibe based and weird but it’s a step in the right direction. Nvidia is notoriously difficult to deal with so the fact we even have this is pretty good lol | 00:37:08 |
| hexa (UTC+1) | the grey area nix-community cache was working prety well though 😄 | 00:38:51 |
| Robbie Buxton | Right but there is no reason we can’t have both! | 00:39:35 |
| hexa (UTC+1) | * the grey area nix-community cache was working pretty well though 😄 | 01:04:18 |
| hexa (UTC+1) | nix-community will drop the remaining cuda jobset at the end of the 25.05 support cycle | 01:04:42 |
| hexa (UTC+1) | so we don't | 01:04:45 |
| Robbie Buxton | That’s a real shame | 01:05:52 |
| Robbie Buxton | Well I guess the silver lining here is we have the cuda teams new hydra instance | 01:06:55 |

| Robbie Buxton | Supported by the great as always work of @[connor (burnt/out) (UTC-8)] @[SomeoneSerge (back on matrix)] and @[Gaétan Lepage] ! | 01:09:03 |
|  ghpzin (moved to @ghpzin:envs.net) changed their display name from ghpzin to ghpzin (moved to @ghpzin:envs.net). | 15:03:30 |
|  All-Purpose Mat joined the room. | 20:36:16 |
| All-Purpose Mat | Hey hey, I was looking into enabling cudaSupport on my system, but it looks like the nix-community cache no longer has CUDA packages. Was this moved somewhere else recently? | 20:39:00 |
 Gaétan Lepage | Yes, you can use this now: https://github.com/nixos-cuda/infra?tab=readme-ov-file#binary-cache | 21:07:45 |
| All-Purpose Mat | Ah sweet, thank you! | 21:13:41 |

 SomeoneSerge (back on matrix) | Hey-heeeey, I was wondering if there's room to optimize our CUDA Weekly timeslot?
Myself, I've had something come up for Tuesday EEST 5PMs, for example.
Let's try crabfit and see if there's maybe an obvious way to reschedule (if there isn't, we just keep the slot)

| SomeoneSerge (back on matrix) | Well in your PR you were putting those hooks directly into stdenv IIRC | 10:55:06 |
| Gaétan Lepage | latest triton, 3.5.0, was merged!
https://github.com/NixOS/nixpkgs/pull/455822 | 16:09:52 |
 connor (burnt/out) (UTC-8) | Nah, they exist outside of stdenv in arrayUtilities. Some people wanted to move them into or use them in stdenv. | 16:27:48 |
| connor (burnt/out) (UTC-8) | Wrote a brief summary of the hooks issue in response here https://github.com/NixOS/nixpkgs/pull/459416#issuecomment-3512684277 | 16:28:33 |

 Daniel Fahey | Can I get a nixpkgs-review pr 460701 --extra-nixpkgs-config '{ cudaSupport = true; allowUnfree = true;}' on this https://github.com/NixOS/nixpkgs/pull/460701 from someone with the spare compute (pretty please) | 16:53:19 |
