| matthewcroughan - nix.how | I don't need much CPU! | 12:48:35 |
 7c6f434c | Hm OK, if you have a ton of RAM and just do the rebuilds at slow rates in background and you can have the cache just for the big packages… | 12:49:20 |
| matthewcroughan - nix.how | yeah you could even have the rebuild switch happen in a systemd service with very very very low resources in a slice | 12:49:58 |

running at low MHz always, to get the best possible battery Pretty sure that CPUs are designed to make this is not the best possible battery, but nothing has enough load control to make the design come true | 12:50:06 |
| matthewcroughan - nix.how | 1cpu 512M memory | 12:50:08 |
| 7c6f434c | Uhm, let me count the ways 512MiB is not enough for nixos-rebuild | 12:50:30 |
| matthewcroughan - nix.how | nix evaluation right? | 12:50:37 |
| matthewcroughan - nix.how | It would be enough if we could share the eval cache, something I know is not secure at the moment | 12:50:49 |
| matthewcroughan - nix.how | And that is a design proposal, to be able to share eval cache | 12:51:13 |
| 7c6f434c | Not sure how well NixOS module system would work for sharing eval caches between non-identical systems
| 12:51:22 |
| matthewcroughan - nix.how | Yeah me neither, I'm just thinking there are no limitations and what the design would look like without limitations | 12:51:41 |
| 7c6f434c | I mean, I don't like NixOS modules for any of the other reasons either… | 12:51:59 |
| matthewcroughan - nix.how | to me, the perfect setup is nix running everywhere for every purpose, to keep everything isomorphic | 12:52:00 |
| 7c6f434c | I kind of want enough RAM to run Nix evaluation on almost everything, that's true… | 12:52:52 |
| 7c6f434c | But for many purposes I am mostly fine with Nix-on-whatever | 12:53:15 |
| 7c6f434c | (Assuming a somewhat clueless but not too malicious and already platform-adapted carrier system) | 12:53:53 |

I kind of want enough RAM to run Nix evaluation on almost everything, that's true… No I mean sharing eval cache would prevent that from being a problem, optionally | 12:56:19 |
| matthewcroughan - nix.how | there are ways we can keep it isomorphic just by messing around with caches and stuff, and fix these problems just like that | 12:56:39 |
