@siraben:matrix.orgsiraben (he/him)level Cthulhu: survive the van Allen belt17:52:16
@fzakaria:matrix.orgfzakariaI posted that I like git's model of allowing subcommands so people can create their own. It lets you have very ergonomic naming commands17:54:42
@fzakaria:matrix.orgfzakaria (git searches for any tool on $PATH that is prefixd with git-) 17:54:50
@fzakaria:matrix.orgfzakaria something like:
nix verify-reproducible <PACKAGE> [--repeat 0] sounds a lot better
17:55:15
@fzakaria:matrix.orgfzakariaWhen it does repeat, losing all the previous attempts was frustrating; but i'm being nitpicky17:56:18
@fzakaria:matrix.orgfzakaria --check was pretty good 17:56:23

In reply to @siraben:matrix.org
It should be easier for people to check reproducibility of their own packages as well
Debian's gitlab (salsa) CI has a default reprotest job. something like that would be nice.

@siraben:matrix.orgsiraben (he/him)Does the reproducibility patches lead to slower binary performance?11:23:48
@rick:matrix.ciphernetics.nlRick (Mindavi)Some do, like the python patches that disable optimized builds and disabling gcc profile guided optimization11:49:27
@rick:matrix.ciphernetics.nlRick (Mindavi)I think there are some wins to be had with making those reproducible as well, but that's quite involved11:50:01
@rick:matrix.ciphernetics.nlRick (Mindavi)And requires intricate knowledge of the code and tooling, so that requires effort upstream11:50:54
@rick:matrix.ciphernetics.nlRick (Mindavi)Which leads to some discussion since PGO does help quite a bit11:59:44
@davidak:matrix.orgdavidak>The NixOS Linux distribution pulled off a technical and publicity coup this month by announcing that the ISO_minimal.x86_64-Linux image is 100% reproducible. The announcement was widely discussed on Hacker News, where the article has received in excess of 200 comments. https://reproducible-builds.org/reports/2021-06/16:44:32
@andi:kack.itandi-Is it just me or is that worded a bit odd?17:49:27
@b:chreekat.netchreekatIt's unnatural English, if that's what you mean. :) Maybe not written by a native speaker?17:50:59
@andi:kack.itandi- The publicity coup is what sound a bit negative to me. 17:51:26
@rick:matrix.ciphernetics.nlRick (Mindavi)It's good that we're on the list :)17:57:49

@tomberek:matrix.orgtomberek The wording does sound a bit odd. I’m not sure what kind of relationship there is between the org and Nix community. 18:16:25

I first heard about this when grahamc announced it on #reproducible-builds on oftc.
18:30:55
@foxboron:archlinux.orgFoxboron I think lamby wrote it because raboof didn't get time? It's well intentioned I assure you :) 18:31:21
@tomberek:matrix.orgtomberek Who runs the infra for r13y? I’d love to start expanding the package sets reported. It provides a nice way to focus community efforts. 19:22:21
@tomberek:matrix.orgtomberekAnswering my own question: looks like it’s grahamc. https://github.com/grahamc/r13y.com19:24:13
