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. :)

    bit ahead, disclaimer that this is a joke and was not my intention.

    THANK YOU FOR PARTICIPATING IN PRONOUN ELECTION DAY 2024 :pronouns:! You’ve now participated in electoralism, and many third parties had a good showing! The two main parties were close, with the Love party getting 8 votes and the Fae party getting 7 votes. The Pup party had a good showing, with 5 votes. Unfortunately I am not converting to puppygirl (yet)

    Woof (:i-voted:)

    Next election in four years :maybe-later-kiddo:

    Results without the BS:

    love/loves: 8 votes (lovely, I’m a based trans now #thallopilled #thallosweep)

    fae/faer: 7 votes (I’m reading Throne of Glass (Empire of Storms/Tower of Dawn) right now…)

    pup/pup’s: 5 votes (sorry pups)

    sie/hir: 3 votes (powerful)

    they/them: 4 votes (idk)

    doe/deer: 3 votes (deer-moding)

    If this taught me anything, it’s that I’m chill with many pronouns. I love love/loves and fae/faer, but found myself hoping for a sie/hir sweep. Honestly, they/them feel like legacy pronouns to me. Doe/deer is also good in it’s own right, and although I’m more of a catgirl myself, I would have run pup/pup’s for a bit had it won.

    pronouns are now she/love/fae/sie on rotation due to slot limitations.

    TL;DR: CONGRATS TO THE LOVES!
