Incidentally, Daniel was my very first CS instructor about 20 years ago, when he taught my Intro to CS class at UT San Antonio. It was the vi editor and K&R book C programming on some ancient green monochrome terminals back then. I remember it as a fairly severe introduction, but he was always great at explaining things properly.
