<PurpleSym>What’s our policy regarding R packages depending on some texlive packages? My problem right now is that r-prereg wants to `knitr` a PDF by default, but it lacks the proper LaTeX packages to do so and fails. Should they be added as propagated-inputs? <PurpleSym>I don’t see `r-knitr` itself depending on any LaTeX stuff. <civodul>well test failures, numerical ones even <zimoun_>civodul: hum, what is the CPU of Bordeaux? Because it looks like the kind of errors dependent on the microarch. <civodul>zimoun_: good point! one of the build machines is an old thing that sometimes causes problems <civodul>Intel(R) Xeon(R) CPU E5-2650L 0 @ 1.80GHz <civodul>so yes, that may well be the problem <rekado>PurpleSym: I’d prefer to only add the texlive-* stuff to r-prereg <PurpleSym>rekado: I tried that, but unfortunately it fails with: `mktexpk: don't know how to create bitmap font for ec-lmcsc10.` 😕 <PurpleSym>The same set of packages works on the command-line. <zimoun_>PurpleSym: I am back to work. :-) Any progress on the Haskell LTS upgrade? I am going to resume this week. <PurpleSym>Progress is slow, because I can only work on that during the weekend right now. <zimoun_>PurpleSym: Thanks. I will give a look so. <zimoun_>civodul: Julia builds fine on my workstation. It is highly probable that the issue comes from the hardware. And I even bet that the failures are not deterministic reproducible. ;-) <rekado>next week I’m supposed to present Guix to MDC folks; ideally with a workshop component where people get to do a few exercises. <rekado>do you happen to have some training materials that I could liberally copy from? <rekado>(I always seem to schedule these things on the first day after my holidays, and I don’t really want to prepare so much during my time off) <rekado>thanks, I’m familiar with the links there. <rekado>I was looking for something tailored to scientists / HPC users <drakonis>highly suspect that some of the presentations on the matter haven't been uploaded <zimoun_>I will convert some in English but not next week. <zimoun_>it is an introduction. Without exercise. <zimoun_>The structure is : 1. CLI search/show/install/remove and present environment variables. <zimoun_>3. use this manifest for introducing transformation <zimoun_>rekado: how long is your presentation? <civodul>rekado: i watched the video and zimoun showed it all: guix package, generations, rollbacks, guix shell, manifests, describe/time-machine, etc. <civodul>but i gather you're supposed to be on holidays :-) <civodul>anyway i really enjoyed the way zimoun_ presented it all <rekado>zimoun_: this is great, thank you! I’ll study your materials and watch the recording. <rekado>(It’s a pity I don’t understand French… I’m missing out!) <zimoun_>I am planning to transform the material into English, but not for next week. <zimoun_>FWIW, I think the progression from day-to-day to core concepts is adapted to scientific practitioners. Well, it is rooted in Python and Numpy but I would like to have a variant rooted in R and bioinfo.
