It was also implemented for TOPS-20, VAX/VMS, Unix, and of course ITS. Read the MIT AI Memo 628: Chaosnet by David A. Moon for most of the gory details.

The advantage is of course that you don't need to keep SYSHST;H3TEXT updated, but instead use the standard domain name system. Drawbacks are that programs need to be recompiled, and that some aren't yet fully compatible with the RESOLV library. text/html 2015-12-30T14:16:10+00:00 Anonymous (anonymous@undisclosed.example.com) https://its.victor.se/wiki/emacs_init?rev=1451484970&do=diff EMACS initialization code Here are some pieces of code to put in your EMACS init file (e.g. * EMACS).
