| louis | Hi, I am trying to setup an x86_64-darwin laptop for a zero-hydra failure meetup tonight and I am running into:
nixer@Nixers-MBP nix-darwin % sudo nix run nix-darwin/master#darwin-rebuild -- switch
warning: $HOME ('/Users/nixer') is not owned by you, falling back to the one defined in the 'passwd' file ('/var/root')
building the system configuration...
error: a 'aarch64-darwin' with features {} is required to build '/nix/store/fpnqc8vj5inchshwwrb7whp9q0wjqvh7-builder.pl.drv', but I am a 'x86_64-darwin' with features {apple-virt, benchmark, big-parallel, nixos-test}
Hint: the failing derivation has allowSubstitutes set to false, forcing it to be built rather than substituted.
Passing --always-allow-substitutes to force substitution may resolve this failure if the path is available in a substituter.
nixer@Nixers-MBP nix-darwin %
I am using the default flake.nix from the nix-darwin README and fwiw I set system = "x86_64-darwin"; in the darwinSystem call.
Is this a known issue?

| louis | Maybe we can do without nix-darwin, but it would have been nice to pull/install some additional tools on the system, also this is weird. | 20:04:40 |
 alexfmpe | good way to brick your system | 22:07:56 |
| alexfmpe | huh no | 22:09:29 |
| alexfmpe | it can hallucinate even with correct inputs | 22:10:03 |
| alexfmpe | it doesn't reason like we do, it does fancy monkey see monkey do | 22:10:42 |
| alexfmpe | if there's a house on fire, half the people throwing buckets of water at it and half the people jumping into the well, monkey-see-monkey-do might arrive at the answer of throwing buckets of water at the well or jumping into the fire | 22:14:37 |
| alexfmpe | use it as seach engine if you must for discoverability, but don't trust anything it tells you without verifying | 22:15:33 |
| alexfmpe | yes the configuration is declarative and you can rollback, but running the actual system gets you side effects | 22:16:51 |
| alexfmpe | it might just allucinate a rm -rf into a boot script or whatever | 22:17:29 |
| alexfmpe | or mess with your password hash and now how do you login? | 22:18:00 |
| alexfmpe | extra fun if a pass is needed to unecrypt the disk | 22:18:25 |
| alexfmpe | I'd add that not even understanding how LLMs can screw you over should be a big reason not to use them | 22:19:39 |

 viraptor | That's a scary view. But in practice you can disallow running any commands and check the changes made. In that scenario it's not different from finding a solution from an unknown source on discourse. Just don't YOLO things. Hallucinations as such are extremely rare if you're running against an existing repo these days. | 04:19:25 |

 K900 | Would appreciate some Darwin understanders taking a look at https://github.com/NixOS/nixpkgs/pull/515997 | 07:53:53 |

 Randy Eckenrode | I hope to get the 26.3 to 26.4 source release updates out this week. I ended up spending last week moving back to 1Password (because the nightlies support native autofill now on macOS), so I didn’t get much else done. | 01:25:17 |
 emily | wait does that mean 1Password in Safari isn't the worst thing ever any more? | 01:43:49 |

| emily | looks like it's still the worst thing ever | 01:48:46 |
| Randy Eckenrode | https://downloads.1password.com/mac/1Password-8.12.18-15.NIGHTLY-aarch64.zip is the last one that works. | 02:39:14 |
| Randy Eckenrode | They’ve made some changes in the more recent nightlies that broke the integration. | 02:39:55 |
| Randy Eckenrode | It’s still WIP, but it fills passwords, passkeys, and 2FA codes via the native autofill. (One big limitation is creating a passkey can’t be added to an existing account. It works on iOS, so presumably not implemented yet.) | 02:40:28 |
