<rekado>finished the slides: https://elephly.net/downies/fosdem2021-slides.pdf

<zimoun>civodul: yes, I can give a try for the HPC report this year :-)

<zimoun>rekado: about service and pack, we discussed with mothacehe last year at FOSDEM exactly this. Well, his views were about images and mine about packages. Somehow, it is similar: provide a file (manifest or operating system) and return an (docker or board) image or tarball. Well, Mathieu or I have been postponing because of the Web UI frontend… Anyway, this service could be awesome! :-)

<zimoun>civodul: I do not see the use case for Nixery… personally.

<zimoun>rekado: your presentation looks really great! Well, the visuals are really nice.

<civodul>oh the presentation is already visible?

<civodul>zimoun: the nixery.dev thing generates Docker images for the packages you give

<zimoun>but already based on Docker images

<civodul>what do you mean?

<zimoun>it use a Docker image to generate another Docker image. But I could have missed something.

<civodul>my understanding is that it generates Docker images exclusively using Nixpkgs

<civodul>layered images

<civodul>:-)

<civodul>rekado: BTW, any news from Twitter?

<civodul>i heard "someone else" had their account blocked

<civodul>but at least they know why

<rekado>civodul: no news from Twitter. They must be too busy with their purge and all the appeals. Now is a bad time to contest account suspension, I think.

<rekado>I trying to record the video for my talk, but I really don’t have a suitable setup for this. I’ll just record video for the intro and outro to simplify things.

<civodul>i did the whole thing live but the result is probably not as good as it could be

<civodul>it's a tradeoff!

<rekado>I’ve got a headache and the longer this takes the more self conscious I become… I’m beginning to think that maybe this was a mistake… :)

<civodul>i've been through that and that's in part why i set myself a hard deadline

<civodul>so i can only cheer you, you're almost done, be brave! :-)

<rekado>yes, I’ll finish this tonight

<rekado>thanks for tolerating my whininess :)

<civodul>:-)

<civodul> https://toot.aquilenet.fr/@civodul/105554483963308770 <- to give you an idea of how professional my setup was

<rekado>WOW!

<rekado>I should get myself a UML book to replace this wobbly tripod I have.

<civodul>heheh, i had forgotten i had such a thing, and i'm glad i've finally put it too good use

<civodul>there was also a natural language processing book (from my partner)

<civodul>i didn't dare put my Guile 2.0 Reference Manual there, it would have been unreasonable

<zimoun>civodul: you setup looks like using Pléiade books ? :-)

<civodul>heh, but these are much less fancy :-)

<zimoun>for the HPC report, do I send email on guix-science or simply to the usual suspect for the first round ?

<civodul>prolly the usual suspects first

*rekado renders the video

<rekado>I’m surprised that blender does so poorly when given a very simple video to render.

<rekado>most of the video is static images. I would have thought it would have some fancy optimizations to cut down on render times, but that’s not the case.

<rekado>this will probably take another hour or so

<civodul>woow, you're a pro, bro

<rekado>pro bro no

<rekado>I gave up on my original plan of interspersing little video chunks in between slides after re-recording the same first two sentences for over an hour…

<rekado>so now it’s just an intro video, lots of slides with audio, and an outro video

<civodul>nice

<rekado>not my proudest accomplishment, but I was never comfortable with video editing anyway, so that’s not unexpected.

<rekado>I’m just glad it’s over.

<civodul>i'm sure it'll rock, as always :-)

<rekado>aw, you’re the best cheerleader :)

<civodul>heheh

<civodul>anyway congrats for completing!

<rekado>now comes the next task: implementing the features that I mention in the video

<rekado>I say that the GWL inherits the ability to bundle up whole workflows (like ‘guix pack’); I should implement this before the video goes live.

<civodul>ah!

<civodul>but how can it possibly work? :-)

<civodul>it has to interact with the job scheduler, right?

<bavier[m]>I like packs, but after using a bunch of them over many months, I kinda wish we had a sort of "pack manager".

<civodul>bavier[m]: sorta like a pack(age) manager? :-)

<bavier[m]>lol, right! :)

<civodul>but yeah, i see what you mean

<civodul>also what rekado wrote on the ML a while ago

<civodul>it's kinda weird: it's tempting to go beyond the simple one-shot usage

*bavier[m] hasn't been able to keep up on the ML for a bit

<civodul>but then you'd need additional tools to make that viable

<civodul>and at that point you might just as well want to run Guix

<rekado>civodul: it would be all the generated job scripts, all the packages referenced by processes, and (a part of) the GWL itself to launch and inspect the thing.

<bavier[m]>I've written a few simple scripts to help with upgrades and gc and such.

<civodul>rekado: i see, makes sense!

<civodul>bavier[m]: did you try running guix-daemon from a -RR pack? would that be helpful for your use cases?

<rekado>I dreamed about it and thought that this could be expanded to produce workflows-as-applications much like PiGx tries to be.

<civodul>interesting

<rekado>whenever I feel tempted to use more than one pack I think I should install Guix instead.

<rekado>it would be nice if packs could be generated in cooperation with a remote $prefix/gnu/store

<rekado>so… really just ‘guix copy’

<civodul>if adjusting "guix copy" to cope with that can be done without too much trouble, that sounds like a good path to explore

<civodul>IWBN to have a proper "store" abstraction in Guix

<civodul>sub-classes, methods...

<bavier[m]>huh,no, I hadn't though of trying to run the daemon from a pack

<rekado>sneak peek: https://elephly.net/downies/fosdem2021-gwl.mp4

<rekado>I just uploaded the rendered video to Penta

<rekado>the audio is a little … muffled sometimes, probably because I wasn’t very careful with lv2-speech-denoiser; was necessary because of very noticeable background noise, though.
