A blast from my past. When I wrote that code I didn’t think anyone would ever read it, more less try to run it. I wrote the paper so that I could visit Barcelona, and thought that fleshing it out with code would impress the reviewers. It seemed to work. Barcelona was incredible. Folks danced to a crazy band playing on the plaza outside the cathedral after Easter mass. Traditional Catalan music, I guess. The “Flying Norwegians” kept me out all night at strange, unmarked clubs. Two men were fighting at 4am on the Ramblas. One hit the other over the head and he fell down, covered in blood. I thought he was dead until he rose up from the ambulance stretcher, swinging his fists, screaming, and ran off into the night. The culinary academy’s menu was only in Catalan, every dish a delectable surprise. Now someone’s actually read the code!
