 Jonas Chevalier | done. thanks for the fix! | 17:52:43 |
| Jonas Chevalier | and purged the Fastly caches for / on channels and releases.nixos.org | 18:07:14 |

 leona | For me, releases.nixos.org doesn't work anymore because (JS error):
Uncaught ReferenceError: baseUrl is not defined
| 07:16:22 |
| leona | not sure if it's because of the change of tgerbet , it doesn't seem to relate that well | 07:17:03 |
| leona | more exactly: releases.nixos.org works, https://releases.nixos.org/?prefix=nixos/ doesn't. The JS buildNavigation function looks completely different | 07:22:23 |
| leona | * more exactly: releases.nixos.org works, https://releases.nixos.org/?prefix=nixos/ doesn't. | 07:22:46 |
 Vladimír Čunát | Yes, that should be from the change. It does add a baseUrl reference. | 07:25:16 |
 tgerbet | Arf sorry I will push a fix | 08:39:28 |
| tgerbet | Done https://github.com/NixOS/infra/pull/839
I cannot be trusted without typechecking 😅 | 09:51:50 |

 Philip Taron (UTC-8) | Folks, what does it take to upgrade the Nix that Hydra uses to a new version? Today it's on 2.29.2 per the footer. 2.30+ has pretty nice memory-size wins. | 17:21:32 |
| Vladimír Čunát | Hydra the SW is coupled to the Nix version it's using. (though I don't know how much) | 17:28:06 |
 K900 | Fairly heavily | 17:29:05 |
| K900 | But also RAM is not an issue | 17:29:05 |
| K900 | Generally | 17:29:06 |
| K900 | (and eval is generally not an issue most of the time) | 17:29:30 |
| Vladimír Čunát | We don't seem to be really running into RAM shortage, though there's not a huge margin sometimes. (zram serves as a buffer) | 17:29:34 |

 @wolfgangwalther:matrix.org | CI's Eval also got faster with 2.30, although I don't know how much that was related to RAM usage and hitting swap otherwise. | 17:31:51 |
| Philip Taron (UTC-8) | What's the unit in these Hydra metrics for "allocations"? https://hydra.nixos.org/job/nixpkgs/trunk/metrics/metric/nix-env.qa.allocations | 18:03:45 |
| Philip Taron (UTC-8) | Number of mallocs? | 18:04:00 |
| K900 | Yes, but also it's not really a relevant metric | 18:04:57 |
| Philip Taron (UTC-8) | As in, when it goes up or goes down, not really an impact on stuff? | 18:05:28 |
| K900 | Yes | 18:06:09 |
| K900 | Generally none of the metrics there are particularly relevant | 18:06:22 |
