 Alexandros Liarokapis | I just now saw the nvidia announcement about third party distribution platforms | 20:13:11 |
| Alexandros Liarokapis | Is flox’s binary cache blessed or are there plans to integrate the binaries to hydra somehow ? | 20:13:57 |
 Gaétan Lepage | Which Hydra are you thinking about? NixOS's official hydra.nixos.org? | 20:16:37 |
| Alexandros Liarokapis | Yea pretty much | 20:16:57 |
| Gaétan Lepage | Then, no. NVIDIA libraries's license do not allow them to be redistributed by anyone, including NixOS's binary cache.
Flox made an exceptional agreement with NVIDIA directly. | 20:18:36 |
| Alexandros Liarokapis | Oh okay interesting | 20:19:03 |

| 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 | grey zone | 00:35:22 |
| hexa | the flox cache is weird, because it doesn't align with nixos channel bumps | 00:35:37 |
| hexa | 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 | 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 | * the grey area nix-community cache was working pretty well though 😄 | 01:04:18 |
| hexa | nix-community will drop the remaining cuda jobset at the end of the 25.05 support cycle | 01:04:42 |
| hexa | 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 |
