@connorbaker:matrix.orgconnor (he/him)In further iterations I’ll try to move the licenses into lib.licenses so they’re available there instead of in _cuda.lib.licenses; we should be using those licenses instead of ad-hoc ones anyway.16:15:14
@connorbaker:matrix.orgconnor (he/him)Which brings me to another great irritation — should older versions of software refer specifically to older versions of the license? Do we need to do something to preserve them or vendor them in tree? If the license contains clauses allowing it to be updated without notice, is that enforceable everywhere?16:17:41

Ignore that; licenses are complicated and I can’t give myself a migraine this early.

@tomberek:matrix.orgtomberekHey, through the GitHub Open Source security program we can get a significant amount of Azure credits. Would the CUDA team be able to effectively use that? Would that make a difference in the maintenance burden?14:10:32
@ss:someonex.netSomeoneSerge (matrix works sometimes)I'm afraid that expert-hours are 146% the scarcest resource right now (as always?)15:48:56
@ss:someonex.netSomeoneSerge (matrix works sometimes) connor (he/him) (UTC-7): repeatedly mentioned he's been experimenting with building nixos images for Azure 15:49:27
@ss:someonex.netSomeoneSerge (matrix works sometimes) If we could have ephemeral azure instances with a mutable nix store that would be amazing 15:50:19

@ss:someonex.netSomeoneSerge (matrix works sometimes) Judging by Gaétan Lepage's emoji reaction, he's already imagining them nixpkgs-reviews going brrrrrrrr. Gaétan Lepage would you have the availability for this one? 08:01:20
@glepage:matrix.orgGaétan LepageTo work on the Azure stuff?09:16:35
@glepage:matrix.orgGaétan Lepage I have gained access to a beefy builder since then, so I'm less constrained than before on the x86_64-linux side of things. 09:17:08
@matthewcroughan:defenestrate.itmatthewcroughan SomeoneSerge (back on matrix): can you bump or have you bumped privately https://github.com/NixOS/nixpkgs/blob/nixos-unstable/pkgs/development/python-modules/opensfm/default.nix#L144 ? 20:19:03
@matthewcroughan:defenestrate.itmatthewcroughanI need it for https://github.com/NixOS/nixpkgs/pull/44200320:19:15
@matthewcroughan:defenestrate.itmatthewcroughanbecause none of the SfM tools work properly in nixpkgs anymore20:19:27
@matthewcroughan:defenestrate.itmatthewcroughanSfM tools are tools that take a dir of image and tag it with inferred data like rotation, coordinates etc, to pipe into gaussian splat utils like brush20:19:52
