<rekado>successfully built tensorflow-with-cuda11

<rekado>ACTION prepares the commit for guix-science-nonfree

<civodul>does tensorflow support ROCm too?

<civodul>ACTION updates the authoring pipeline for the report

<civodul>quiz! i have an A4-sized PDF file for the cover and i want to (1) make it A5 and (2) concatenate it to the document; what tool do i use?

<rekado>I would probably try to use gs (ghostscript)

<rekado>do you want to resize the A4 page or cut it into two A5 pages?

<rekado>I thought the cover was meant to be understood as the back (on the left) and front (the A5 segment on the right)

<rekado>civodul: I’ll have to check ROCm support later; problem is that we have no AMD cards here where I could test things.

<civodul>rekado: i’m trying things with gs, not really understanding what i’m doing though

<civodul>gs -o a5.pdf -sDEVICE=pdfwrite -sPAPERSIZE=a5 -c "[/CropBox [421 0 842 595]" -c " /PAGES pdfmark" -f orbital-cubes-plus-cover.pdf

<civodul>“statements dreamed up by the utterly deranged”

<rekado>hmm

<rekado>for printing wouldn’t this page just be the outer page? So it would still be printed as A4, but folded around the A5-folded booklet

<civodul>correct

<civodul>but! i’d also like to have the non-booklet version

<rekado>oh, right

<civodul>so a “regular” A5 PDF

<rekado>so, the above command is supposed to crop the cover to A5?

<civodul>yes, except that the offsets (in points) are slightly off for reasons i don’t understand

<rekado>could it be that orbital-cubes-plus-cover.pdf includes print margins and isn’t exactly A4?

<rekado>(I haven’t checked yet)

<civodul>Evince says A4

<rekado>bleh, our ISC tutorial has again been rejected

<civodul>yup, how fun

<rekado>this seems to work fine: guix shell mupdf -- mutool poster -x 2 orbital-cubes-plus-cover.pdf /tmp/out.pdf

<civodul>neat

<civodul>the front page is not centered, actually

<rekado>yes, I noticed. Not sure if intentional.

<civodul>i feel stupid: i’m unable to split the PDF, extract a page, merge it with the rest of the document

<civodul>i’ve tried gs, mutool, pdfjam, …

<civodul>everything sucks in its own way

<civodul>gs has rounding errors apparently

<civodul>“mutool draw -o front.pdf orbital-cubes-plus-cover.pdf 1” almost does the job, except that it drops some of the graphics

<civodul>there must be a conspiracy to achieve this level of sadness around PDF tooling

<rekado>yeah, it’s a really frustrating problem space.

<civodul>ACTION tries podofo

<civodul>i committed what i have in ‘doc/build.scm’

<civodul>it kinda works, except for the booklet

<civodul>for some reason pdfbook2 gets it wrong

<civodul>maybe the cover and back are not exactly the right size

<civodul>go figure

<civodul>soooo!

<civodul>orbital-cubes-plus-cover.pdf is actually 29.6cm (!) large

<civodul>it misses .1cm

<zimoun_>For the record, one the best unreproducible stuff: https://github.com/dils-popgen/dils/blob/master/DILS.def#L15

<zimoun_>Hardcoded network proxy

<zimoun_>Then Debian + Conda + Git clone

<zimoun_>But that works… I hope. :-)

<rekado>civodul: oh! You can re-export it from svg.

<rekado>zimoun_: the magic is all in the proxy, freezing the state of the world.

<zimoun_>civodul: A4 -> A5, I use a LaTeX package (as for doing booklet)

<zimoun_>PDF concat, I use: https://gitlab.com/zimoun/my-conf/-/blob/bb4ee4ba750688d240ab6a5ccb71a696a9042eb0/.local/bin/pdfcat

<zimoun_>civodul: About booklet, I was taking about this: https://gitlab.com/zimoun/zimoun.gitlab.io/-/blob/d1a1d2083f669e9267910300ed9f84bd0ff79c74/src/posts/assises/booklet.tex

<zimoun_>HTH

<zimoun_>rekado: yeah. It reminds us how diverse we are when we speak about reproducible. :-)

<jonsger>civodul: pdfseparate from the poppler package maybe?

<civodul>jonsger: i’ll give it a spin, thanks for the tip!

<civodul>problem is, i managed to do the split/merge with ghostscript

<civodul>but now it might be pdfbook2 that’s broken

<civodul>hard to tell

<civodul>for the record, it’s right here: https://gitlab.inria.fr/guix-hpc/website/-/blob/master/doc/build.scm#L372

<civodul>i take patches! :-)

<civodul>i’ve received a dozen proposals of other tools on the Fediverse, uh

<civodul>(to reproduce, run “guix build -f doc/build.scm” and notice that ‘full-book.pdf’ is wrong)

<zimoun_>civodul: I generate booklet using TeX package name ’pdfpages’. 1. I produce A4 regular PDF then 2. I include it with the LaTeX snippet above and run lualatex and done. No gs.

<civodul>zimoun_: do you think you could squeeze that in ‘doc/build.scm’?

<civodul>pdfbook2 used to work fine, but there’s something here that makes it go wrong

<zimoun_>I will give a look. Maybe it will not work because all the Crop etc.

<zimoun_>Are cover.pdf and back.pdf produced as A4?

<civodul>A5

<civodul>ACTION has to go

<civodul>ttyl!

<zimoun_>ouch! When compiling a report for PDF requires boost…

<zimoun_>and samba is also in the picture.

<zimoun_>We have an issue with our graph of dependencies. It is often way too much

<reedm>Hi All, I was very excited to see the blog post on ROCm and HIP coming to guix. In the post, there is a link to "supported GPUs". This list is quite small, and in fact doesn't even contain the gpu used in the example. From some googling, there seems to be a much larger number of GPUs which work, but are not officially supported, but I've had a very

<reedm>hard time figuring out when this is the case. Does anyone here have experience with ROCm/HIP on guix with consumer GPUs?

<rekado>no idea. I also read that a lot more GPUs work, but there’s no official list.
