As expected, my shoulder and side are a little improved today; I still expect them to be fine by the weekend. After work yesterday I did still manage to get useful tasks done, mostly ones I would normally do at the weekend except for that we didn't get back from England until late Sunday afternoon, with more Lancashire cheese in hand. At work I have been making slow but steady progress with learning some basic Ansible; it helped to be pointed to our repository of roles which are amenable to git grep --recurse-submodules …. Today I got a simple additional role to seem to actually work despite my having had a headache for what must now be over twenty-four hours. Painkillers have at least reduced it somewhat. Unfortunately I am no closer to identifying triggers.
