<rekado>we’ve had a number of GWL releases last year. Finally something I don’t have to rush before the report :) <civodul>there's no canonical blog post or article about GWL, right? <rekado>true. Even the manual’s introduction is very light on why we’d even bother doing this. <rekado>I only ever discussed this in my presentations at FOSDEM <zimoun>rekado: I was invited a seminar back on December where I presented Guix. I had questions about GWL. Yeah! <zimoun>A The Vision would be worth, IMHO. :-) <PurpleSym1>Hm, is Guix’ channels.scm order sensitive? I’m getting different profiles with guix pull -C vs guix time-machine -C and the only difference is that guix describe reports a reversed order of channels. <civodul>PurpleSym1: could you tell what the difference is between those profiles? <civodul>as in "diff $P1/manifest $P2/manifest" <PurpleSym1>civodul: Like `guix describe` the order of channels differes. <civodul>PurpleSym1: ok, that's not great, but normally inconsequential <civodul>we could/should canonicalize channel order <PurpleSym1>civodul: I’m trying to figure out how to ensure a given Guix profile in /gnu/store/…-profile matches a given channels.scm and using cached-channel-instance I have to reverse the channel list. That’s how I noticed. <PurpleSym1>(When sharing projects we cache the Guix profile for speed and need to make sure it’s “genuine”.) <PurpleSym1>Which is harder than thought, because it takes a full minute to build a profile and then it’s only cached for one user 😕 <civodul>if you use time-machine, you get caching for free though <rekado>I noticed a little problem: “guix time-machine --commit=…” will still get all the channels but only set the ’guix channel to the specified commit <rekado>(or at least it looked this way) <rekado>I had to give it a channel file to make it only use the 'guix channel <rekado>not sure if that’s intended behavior <civodul>that's intended, but i see it can be confusing <civodul>by any chance, did one of you fearless scientific hackers try to build gloo and pytorch with rocm? <zimoun>civodul: No. “Machine learning” is becoming against my ecological principles. :-) <civodul>another thing i dislike about machine learning is when it's used as a substitute for analytical solutions <PurpleSym1>civodul: re channel order: Should I open an issue?
