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. :)

    i'm doing it again sorry if this is too off-topic (spoilers for homestuck 2792)

    In general I'm liking the more varied art styles for the characters

    1. i can't get over how cute the art is in this little Flash interactive thing, omg the sprites i am swooning and now I have decided Vriska is my favourite character. also Feferi is so pretty omg. so much gender envy is happening here right now. who did this art, i need to become them
    2. related, but the word spidersona will live rent-free in my head for a while
    3. there's so many listed music tracks for this one but i uh got lost because it was late and didn't find most of them, lol
    4. also I loved the actual drawings of :?, good bit

    (I should mention tho in case anyone is interested in checking it out that some of the language is pretty dated as it's from ~2010 and kinda has its "edgy" roots, the unofficial collection has a whole bunch of content warnings and I think that's great that they did that but I feel it needs to be said)

    this silly little comic is making me believe in people and my ability to actually have social connections again, so I appreciate that. I'm not sure what class of treat enjoyer this makes me, perhaps Treat Mage?

      love vriska, love feferi and all of the fish people.
      i love how furry-adjacent the series is as a whole
      some of the tracks are held in the trickster mode parts, make sure you look up a guide for those
