I heard that Thien-Thi Nguyen passed away last year. This was recently reported on the emacs and gnu-community mailing lists, but I don't think it was mentioned here (and apologies if it was already mentioned.)
TTN was a bit of a maverick in the Guile world, preferring the 1.x series and maintaining libraries for it. TTN wrote a binding for Guile to SDL 1, maintained a library of www and cgi routines for Guile, wrote a postgres binding, and for a long time maintained his own fork of Guile 1.4. TTN and I had a few conversations about Guile and we collaborated for a moment on GNU Serveez, in which he was kind and helpful. Regards, Mike Gran
