The problem of (Unix) swapfiles and server backups
There are two pieces of good news for us in our particular environment (with Ubuntu 22.04 servers). The first is that in general our swap files are small; an extra GB for the moderate number of servers that we back up won't really break the bank, not when set against the amount of data from our fileservers. The second is that Linux doesn't update the modification time for swap files when they're used, so to a backup system these look like files that never change. Since they never change, they'll only be included in full ('level 0') backups, not in the much more common incremental backups that our backup system does.

Running Shell in Builder
Builder has been absolutely wonderful for a designer to dive in and fix up graphics assets for Application. It allows to easily build and test run patches before submitting a merge/pull request on apps hosted on gitlab or github. Ideally you’d press the run button and voilá.
What has been far from wonderful — doing even one line fixes for the GNOME Shell was very hard to test for anyone not building shell daily. getting the environment ready every release has been a chore. From virtual machines, jhbuild, toolbox, jhbuild in VMs to jhbuild in toolbox there was a dozen of way to fail building the latest shell.
