"As an undergrad in the spring of my senior year in 1984 I took CS 503 Operating Systems with Professor Doug Comer. We were using the first edition of his XINU book. Seeing a Unix-like operating system built from the ground up in a layered approach was a seminal learning experience and prepared me so well for the things I went on to do as a Software Engineer writing embedded code. Prof. Comer was so skillful at communicating hard concepts and artfully building both a complex computer system and my own knowledge base from the ground up. Was that his first book? I understand he has now written many other college level textbooks that are widely used in many places. Almost 40 years later I realize my personal experience with that course is an analogy for my Purdue CS degree. I didn't realize then that I was receiving such a high quality learning experience in that course, but it later proved to be so enriching to me and set me up for success. In the same way, everywhere I've gone around the world my Purdue degree has also proved to be so well-regarded by others. In both cases the passage of time has revealed that what I received was so much more valuable than I knew."
