Little known random Brian Kernighan facts:

* He joined Princeton’s CS department in 2000 but taught at least one class there as early as 1993 while still at Bell Labs Research (on sabbatical?)

* One of his students regularly brought a 386sx laptop (running pre-1.0 Linux) to class and when Brian was asked more obscure questions about what awk did which he couldn’t remember, the student would run commands in awk and feed Brian the definitive implementation answer. So Brian had some exposure to Linux moderately early on.

* Here’s a writeup from him on putting AT&T’s toll free phone directory on the internet back in fall 1994: https://www.cs.princeton.edu/~bwk/800.html
