DEMOS (Dialogovaya Edinaya Mobilnaya Operatsionnaya Sistema: Russian: Диалоговая Единая Мобильная Операционная Система, ДЕМОС, lit. 'Interactive Unified Portable Operating System') is a Unix-like operating system developed in the Soviet Union. It is derived from Berkeley Software Distribution (BSD) Unix.

It's development was initiated in the Kurchatov Institute of Atomic Energy in Moscow in 1982, and development continued in cooperation from other institutes, and commercialized by DEMOS Co-operative which employed most key contributors to DEMOS and to its earlier alternative, MNOS (a clone of Version 6 Unix). MNOS and DEMOS version 1.x were gradually merged from 1986 until 1990, leaving the joint OS, DEMOS version 2.x, with support for different Cyrillic script character encoding (charsets) (KOI-8 and U-code, used in DEMOS 1 and MNOS, respectively).

Initially it was developed for SM-4 (a PDP-11/40 clone) and SM-1600. Later it was ported to Elektronika-1082, BESM, ES EVM, clones of VAX-11 (SM-1700), and several other platforms, including PC/XT, Elektronika-85 (a clone of DEC Professional), and several Motorola 68020-based microcomputers.

The development of DEMOS effectively ceased in 1991, when the second project of the DEMOS team, RELCOM, took priority.

An archive of the DEMOS source code can found here: https://github.com/bpr97050/DEMOS There's some interesting comments and mailing list archives in that repository as well. :)

    same CWs, add anxiety/stress

    It's actually looking like Trump might try to revert things like passports https://hexbear.net/post/3861287?scrollToComments=false (depressing read, but should be read). I've already started looking into DIY, because even though I'm in a "blue" state, getting HRT from healthcare providers looks like it's going to be much more difficult, if even possible. I wonder how long passports made before this executive order might last, but I worry that they might just invalidate them all.

    On courts, I worry that the Supreme Court is all-too-ready to shoot down any challenges, and with a likely Republican supermajority (not to mention dems that would be in favor of this). I am kind of stressing about what could happen as a result of this.

      Do what we've always done. Stick together. Set up our networks. Support one another. Love one another. Protect one another.
