This brought back shades of 20 years ago to me

… This brought back shades of 20 years ago to me. I went back to school to add a credential after my name to make myself employable. My experience running the back office for a long-distance reseller (FoxPro 2.6 database: application support, running customer service, billing, reporting, and being the networking yeoman) didn't look impressive on my resume without some additional alphabet soup. This was my programming languages -- interpreters class. Dr Daniel Friedman ran a teach-along that culminated in implementing miniKanren in scheme. First day of class, the front row was empty. I was ten years older than every other student in the room (with the exception of Will Byrd). I sheepishly shrugged and took one of the offered seats in the row. For the next hour, the sheer force of scheme being written on the whiteboard blew my mind open. That continued for 16 weeks, three days a week. I highly recommend the experience. I (probably) still have a pre-press copy of The Reasoned Schemer in a box in my attic. It was one of the goodies handed out on the last day of class.
