@emilazy:matrix.orgemilythe generation timestamp on r13y.com is older than that archived version21:39:56
@emilazy:matrix.orgemilyso I guess it's some caching issue21:40:00

@tomberek:matrix.orgtomberekDid it happen?!22:03:41
@grahamc:nixos.org@grahamc:nixos.orgcongratulations everyone, this is fantastic!23:23:22
@emilazy:matrix.orgemilythat taviso comment just straight up assumes that everyone gets their binary software builds straight from the source code vendor :(23:56:47
@emilazy:matrix.orgemilyanother criticism of reproducible builds I encountered today was "this is useless... you have to pin all your dependencies!" >_>;23:59:47

@grahamc:nixos.org@grahamc:nixos.orgdon't worry about it :) it is great to see some people be grumpy about the good work we're doing01:02:43
@hexa:lossy.networkhexaheh, taviso has been downvoted01:07:05
@hexa:lossy.networkhexahis post is essentially dead01:07:30
@grahamc:nixos.org@grahamc:nixos.orgif I'd known we'd see such response to hitting 100% I'd have thought more carefully about the text at the bottom, and how to refer to the rest of the ecosystem and the fact that we're benefiting a lot from the ecosystem01:17:37
@grahamc:nixos.org@grahamc:nixos.organy suggested text on how to communicate this?01:20:24

@b:chreekat.netbryan
In reply to @grahamc:nixos.org
any suggested text on how to communicate this?
A short history of the effort?
01:24:33
@withoutwithin:matrix.orgXewhat compiler bundle does nixos use as the root of the reproducibility effort?01:29:59
@hexa:lossy.networkhexayou mean what's in stdenv(.cc)?01:30:39
@hexa:lossy.networkhexa
❯ nix-build -A stdenv.cc
/nix/store/gg2rq3hrl3rf92nq6dnqhdyyxaa89aqf-gcc-wrapper-10.3.0
01:31:07
@withoutwithin:matrix.orgXeis that c compiler used to rebuild itself?01:34:24
@grahamc:nixos.org@grahamc:nixos.orgthat is already a post-bootstrapping gcc01:35:12
@withoutwithin:matrix.orgXeoh, what's the bootstrapping root then?01:35:38
@grahamc:nixos.org@grahamc:nixos.orgit is a fairly standard set of tools that are made sure they can be built reproducibly and then tar'd up01:36:41
@grahamc:nixos.org@grahamc:nixos.org1s01:36:41
@grahamc:nixos.org@grahamc:nixos.org Xe: https://search.nix.gsc.io/?q=http%3A%2F%2Ftarballs.nixos.org%2Fstdenv&i=nope&files=&repos= 01:38:17
@ziguana:ziguana.clubziguana joined the room.01:39:00
@withoutwithin:matrix.orgXeand the ultimate root is some set of tools that eelco originally made nix with?01:39:34
@grahamc:nixos.org@grahamc:nixos.orgiirc they came from suse01:40:31
@grahamc:nixos.org@grahamc:nixos.org~forever ago01:40:59
@withoutwithin:matrix.orgXeso i guess if somehow there's a "more verifiable" way to make the root bundle of compilers then using it would boil down to replacing the tarball in bootstrapTools?01:42:23
