@zimoun will present « Guix + #SoftwareHeritage Source Code Archiving to the Rescue of Reproducible Deployment » on Saturday: https://fosdem.org/2025/schedule/event/fosdem-2025-5897-guix-software-heritage-source-code-archiving-to-the-rescue-of-reproducible-deployment/
The presentation is about the work we did to integrate GNU #Guix with the @swheritage archive, so that when users try to (re)build packages whose source code has disappeared from the new, it will still work!
This is key for scientific #reproducibility. See our #ACMREP paper from last year for more details: https://upsilon.cc/~zack/research/publications/ieee-sw-repro-builds.pdf
