I had heard of him from his PhD Dissertation which was something like 35 pages long for Knuth (!) on random number generators. He finished at Stanford in 1977 and in 1978 he was porting Unix? How did that happen? I'm with Lawrence, I'd love to hear this. This thread is the first I've heard about John Reiser and London. I don't remember anything about them in the Bell Labs journals. I can say it is not a stretch to go from school to porting, I did that. School is amazing at making you feel like you can do anything. I took the grad compiler class, you could take one of them or two of them at a time, my buddy Rob Netzer and I took two together and we wrote a big subset of the ADA language in a semester. You slow down when you have to make a product that works in the face of people doing silly (aka stupid) things. Error checking is a thing, compiler error messages that point to the exact problem are a much, much bigger thing. Gcc is very good at that, I've got a lot of respect for gcc, I know how hard that is.
