The annual #Guix-HPC report is out!
That was a good opportunity to raise the issue of how hosted notebooks deprive scientists from their autonomy and undermine #reproducibility. "There is no cloud".
“Identical files across subsequent package revisions”:
Estimating how much data is identical between subsequent revisions of a package, with an eye towards optimizing substitute downloads.
Luis is the designer of the Guix and Guile logos, of the Guix and Guile web sites, and of the 1.2.0 release illustration. 👍
Don't miss this opportunity to support Luis and to be in fashion!
Do not miss the release song and all the niceties!

#FreeSoftware for everyone, in respect of linguistic and cultural diversity!
Just discovered 'perf timechart', and it's wonderful!
Here's an example: the timechart while running "guix archive --export -r $(guix build coreutils -d)" (exporting lots of small files). Lots of grey parts (idle) and very little blue (running): 'guix' and 'guix-daemon' do next to nothing apart from waiting for all these tiny 'guix authenticate' processes: for each store item, we spawn one of these. There's room for improvement...
