The last article of the latest issue of the Co= mmunications of the ACM
that appeared electronically earlier today is a brief interview with
this year's ACM Turing Award winners, Al Aho and Jeff Ullman.

The article is

=C2=A0 =C2=A0 =C2=A0 =C2=A0 Last byte: Shaping the foundations of programmi= ng languages
=C2=A0 =C2=A0 =C2=A0 =C2=A0 https://doi.org/10.1145/3460442
=C2=A0 =C2=A0 =C2=A0 =C2=A0 Comm. ACM 64(6), 120, 119, June 2021.

and it includes a picture of the two winners sitting on Dennis
Ritchie's couch.

I liked this snippet from Jeff Ullman, praising fellow list member
Steve Johnson's landmark program, yacc:
