Two weeks of updates, since I forgot last week.

Resolute Snapshot 2 release

  • Played again with AI, this time Gemini, to help out write a tiny helper script for the release. Find out more in all the individual commits and comments in this PR but in short, I’d say it has the same kind of issues than Copilot: it doesn’t think, so makes silly mistakes, and can’t figure out the semantic of things, quickly leading to badly named variables that add to the confusion of reading a script that often splits the responsibilities of the work weirdly between functions.
  • Released snapshot 2!

error tracker

  • Updated whoopsie on Resolute to upload crashes to the new Python3 daisy backend: so far this new daisy is working just fine! :rocket:
  • Investigated the scope of work needed to get django-tastypie to work again on Noble. It’s currently pretty bad, with the package being mostly useless.
    Work to fix that is already happening upstream: https://salsa.debian.org/python-team/packages/django-tastypie/-/merge_requests/2
  • Continued working on reviewing and fixing Copilot’s work regarding replacing pycassa with cassandra. This includes introducing some automated testing to help regain confidence in that old code, which Copilot has contributed to with great success once everything was kickstarted on the right track!

Jenkins CI

  • Fixed a couple of issues regarding automated upgrade testing.

Merge-O-Matic

  • Reviewed and provided feedback on @seb128’s work to charm it (yay! :rocket:)

livecd-rootfs

  • Reviewed and provided feedback on @mwhudson’s work to build ISOs (yay! :rocket:)

manpages.ubuntu.com

  • Reviewed, merged, and deployed @rkratky’s PRs making use of modern Ubuntu assets and updating the documentation links. Thanks!

Happy EOY everyone, 25 was wonderful, see you in 26 :evergreen_tree:
