Subject: [TUHS] [tuhs] ACM Turing Award for 2020: Unix roots

This just came in:

ACM has named Alfred Vaino Aho and Jeffrey David Ullman recipients of
the 2020 ACM A. M. Turing Award

        https://awards.acm.org/about/2020-turing

for fundamental algorithms and theory underlying programming language
implementation and for synthesizing these results and those of others
in their highly influential books, which educated generations of
computer scientists.

Most of us probably have several of their books on the shelf; I certainly do!
