Goodbye to Thien-Thi Nguyen

[Amin Bandali]

We have learned with deep sadness that Thien-Thi Nguyen (ttn) died in
October 2022.  Thien-Thi was a hacker, artist, writer, and long-time
maintainer and contributor to many GNU programs as well as other free
software packages.  He was the GNU maintainer of the rcs, guile-sdl,
alive, and superopt packages, and he was working on GNU Go as well.

Thien-Thi especially loved GNU Emacs, GNU Taler, and GNU Go: he was
the author and maintainer of the xpm, gnugo, ascii-art-to-unicode,
and hideshow GNU Emacs packages and made substantial contributions to
many others such as vc, as well as to GNU Taler and its documentation.

We greatly miss Thien-Thi in the free software community - his death
is a great loss to the Free World.
