In a former job, I developed “software” (I clicked together some LabVIEW…) for custom designed scientific experiments, which many other researchers (mostly PhD students) would use. Wrote detailed SOPs for their usage, because everything was wonky and in constant evolution, and in some circumstances, data generated could be wrong. So I put a toggle switch with some cryptic acronym on the panel which was told to be flipped in the SOP when users reached the part where following instructions was really critical. The toggle switch did nothing but to log time and date and what user was logged in. When discussing weird data later on, first thing I did was to check whether that log existed, and if not heavily scrutinized the data with respect to errors that could be induced by not following the SOP.
I feel that. My dad sold my childhood home after my mother’s passing and moved out a few years ago. I had not lived there for 25 years or so, but three of my cats were buried in the yard because I lived in rentals during that time. The last walkthrough through the house was of course emotional, but strolling through the yard past the trees where I put the little furballs to rest really hit me.
