Spotter missed its fire today, which it was not supposed to do. I traced it to the network requests and spent the time hardening them so the same failure doesn’t repeat quietly next time. The rest of the day went to the Uboat, hours at the periscope with little to show for it but the pleasure of it. In between I bought a suit and disliked every minute of the process, the fitting, the mirrors, all of it. Small satisfactions and small irritations, in about equal measure.
