@gomli Oui, cet entretien reste rapide et superficiel. Merci pour les liens !

@SReyCoyrehourcq @zimoun Mais il a peut-être bon, le message d’erreur ? :-)

Quand tu fais « guix authenticate hashducommit clefgpg », tu spécifies un commit d’introduction autre que l’original. Donc peut-être que ça passe, mais en fait ça ne vérifie rien.

Je vois qu’il y a une marge d’amélioration sur l’UI/UX et/ou doc en tout cas !

@SReyCoyrehourcq Salut !

Quand on pousse sur la branche « keyring », il faut désactiver le crochet pre-push.

(Le crochet pre-push n’est pas encore installé si on suit les étapes d’initialisation du dépôt décrites dans l’article, donc c’est bon, mais si tu ajoutes des clefs par la suite dans la branche il faut le désactiver.)

C’est pas pratique, faudrait corriger ça !

@zimoun

@futurile @luis_felipe How about “Guix”? :-)

“Targeting the Cray/HPE Slingshot interconnect”
https://hpc.guix.info/blog/2024/11/targeting-the-crayhpe-slingshot-interconnect/

Includes MPI benchmarks showing that—guess what!—the vendor-provided MPI doesn’t perform any better.

#Guix #HPC #OpenScience

@sharlatan Quite an achievement! That’ll make lots of people happy.

Drivers and libraries for the Cray/HPE Slingshot #HPC interconnect are now #FreeSoftware…
https://github.com/HewlettPackard/shs-libcxi

… and ready to land in #Guix 👇
https://issues.guix.gnu.org/74419

Quite a milestone and definitely something to celebrate for those at #SC24!

@boegel This workshop on reproducibility on HPC looks nice, even couches aside. ;-) I’m not attending but curious about the takeaways.

@futurile Oh right, I didn’t see it from that perspective (that using snap was a way to have a form of transactional upgrade/rollback).

But yes, I do think they’d be better off rebasing on top of Guix or NixOS (Mark, if you read this, we can talk. ;-)).

(They could even display ads while ‘guix pull’ is running!)

@futurile Seen from a distance, I think a solution would have been to keep using apt exclusively; the “App Center” could very much have apt as a backend.

In the end, it seems that in the hope of getting a share of the remaining 99% of the market, all they achieved is to alienate a subset of the 1% that actually uses it.

Anyway, who am I to judge commercial distros? :-)

Anecdote: the (pretty) installer would crash badly at the sight of the NTFS partitions or something that were on the target disk. I partitioned it with ‘fdisk’ and then the installer was able to proceed.

I remember of a similar bug that was reported (and fixed) against the Guix System installer a while back; nice to see we’re in good company.

I found this quite evil because I thought you could still choose between apt and snap. That’s not quite the case.

Anyway, that Firefox packaged who knows how has all the surveillance things turned on: completions by Google in the location bar before history completion, Google as the default search engine, “telemetry”, and of course no ad blocker or anything by default.

This has a very “Windows feel”.

Turns out there’s a “fake” (transitional?) ‘firefox’ .deb:
http://us.archive.ubuntu.com/ubuntu/pool/main/f/firefox/firefox_1snap1-0ubuntu6_amd64.deb

/usr/bin/firefox in that package ends with: exec /snap/bin/firefox "$@".

And ‘debian/firefox.preinst’ basically runs ‘snap install firefox’. QED.

I discovered Ubuntu, 2024 edition (no I’m not switching).

Once installed, it comes with Firefox preinstalled, with the icon showing up in the GNOME dock.

There’s a ‘firefox’ .deb package installed, but hey ‘dpkg -L firefox’ shows that it’s almost empty, with little more than /usr/bin/firefox, and — surprise! — ~/.snap/firefox occupies quite a bit of space. Hmm! 🤔

"Reducing Legacy Code's Carbon Footprint with AI"

@Parnikkapore Jes, evidente. :-)

Guix-Jupyter 0.3.0 released!
https://hpc.guix.info/blog/2024/11/guix-jupyter-0.3.0-released/

This is a long-overdue release of the one Jupyter kernel that can deploy the execution environment of notebooks in a reproducible fashion.

The release announcement comes with a call for help: the project needs you!

#Guix #Jupyter #Guile

Look, maybe you 🫵 can join the fabulous German, Romanian, Swedish, and Ukranian translators who already translated 100% of the messages found in 1.0.0rc1!
