 samasaur | man -wa ln may be helpful? | 16:00:00 |
 antifuchs | oh, yep, that's the flag. it's the regular built-in manpage. I just got confused by which ln was used in the activation script (: | 16:01:53 |
| antifuchs | (that script uses the coreutils one, which stumbles over -h) | 16:02:35 |
 emily | seems like an empty rebrand to me | 18:22:00 |
 Randy Eckenrode | Probably, but dropping down to only six performance cores doesn’t seem very pro. | 18:55:49 |
 Sarah Clark | It sounds like they didn't improve the cooling enough so we get a pile of the slower cores | 19:26:57 |
| Sarah Clark | I have a M3 Max and set num-cores to not touch the efficiency cores most of the time. | 19:28:02 |
| Randy Eckenrode | I limit the number of simultaneous jobs because otherwise Nix happily schedule way too many simultaneous builds for a workstation. | 19:29:44 |
 WeetHet | By the way, did someone investigate the QoS classes in the end? | 21:09:12 |
|  PJ set a profile picture. | 23:49:02 |

|  @logn:zirco.dev left the room. | 02:29:05 |
| emily | hexa: do you have any feeling for roughly when Darwin staging queue started being especially bad? I am wondering if it might be https://github.com/NixOS/nixpkgs/pull/442945 (because of the mistake mentioned in https://github.com/NixOS/nixpkgs/pull/490358), though that was a few months ago now | 15:04:22 |
| emily | I'm inclined to merge https://github.com/NixOS/nixpkgs/pull/490358 and see if it makes the next cycle less bad, but I probably won't notice one way or the other myself :) | 15:04:55 |
 hexa | no, sadly not | 15:05:45 |
| hexa | maybe vcunat remembers | 15:06:02 |
| hexa | I'd say for the last two months I had to reboot macs a few times because they ran full and had stuck jobs | 15:06:33 |
| emily | vcunat? :) | 15:07:00 |
| emily | it seems plausible that libc++ hardening could make Clang meaningfully slower or whatever | 15:07:10 |
| hexa | anyway, the backlog this time was around 55k packages when linux was finished | 15:07:36 |
| hexa | and the machines are doing like 10k per day? | 15:07:54 |
| hexa | I think we tend to say the current total capacity is like 30k jobs per day | 15:08:31 |
| emily | ok, I'll merge it and we can see | 15:11:41 |
| emily | could also just be more jobs appearing constantly and Darwin being some multiplicative factor slower I suppose | 15:12:15 |
| Lun | is this a good excuse to pgo&bolt the stdenv clang | 15:18:13 |
| emily | nah, would be bad for reproducibility | 15:18:49 |
| Lun | f | 15:18:55 |
| hexa | i'm like 20% on board with reproducibility being a focus of the project | 15:19:17 |
| emily | stdenv being inherently non-reproducible is certainly not okay | 15:21:07 |
| emily | for leaf packages it's less concerning | 15:21:17 |
