So my group's project was writing the VM in C, and only two of us contributed as predicted. Our VM passed the prof's test suite (actually written by our adversary, "Team Lambda", IIRC). So I have a "It all started with a NOOP" story too.
This prof really was a genius himself and an expert in his field. He introduced many of us to the wisdom of Knuth. Our professor once recounted a story about having written an earnest letter to Knuth asking, "I know you are busy, but do you have time to do a lecture on compilers for my class?" He received back in the mail the original letter and envelope, enclosed in another with the "I know you are busy" underlined. My puns are kind of dumb, so I'm not sure he ever understood what I meant. He did ask us what our individual contributions were, and proof there of. My teammate followed me to State U.'s security headquarters begging for some of my test cases.
Have a nice day everyone!
