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. :)

    mental health

    I can’t believe I haven’t posted in over a month. I have been mired in a deep depression that I’m only now slowly crawling my way out. Not doing great yet, but not as bad as I was either.

    I need to break my habit of disconnecting from everything when I get like that. I’m sure it only compounds my depression to be anti-social and isolated. Easier to say now than to do in the midst of it though.

    Visited parents with my brother and after we got back to our place, he was like “mom complimented me on my tit growth*. Did she do the same for yours?”

    *as growing chest muscles from working out. He always talks about working out his chest as getting bigger tits.

    Well the meds are doing something, i think. Ive been more productive today than I have been in weeks! Ive been less freaked, more restless (in a good way) and kinda gone off a couple times. But its going well I think… I hope its going well… Its been so long since ive been medicated, i really hope this time things will be different and the meds will work better.

    My big test will be going shopping on my own at a big store, but thats for another day.

    I HATE having things I want to say, thoughts I want to share, but knowing I can’t. Inappropriate to share here, therapist will try and send me to inpatient. Also just like, fuck him. Last session he brought up for the fucking hundredth time he’s worried I’m “being influenced” and “going with the flow”. Dipshit. Because I guess that’s what people with avpd do. Honestly I should just never mention my diagnosises to anyone again if they’re going to be used against me like that.

    Explained to my mother why I won’t regret trying estrogen using the dialectical materialist theory of knowledge.

    There is nothing that is not better explained using a philosophical framework.

    how would one best go about talking with other, non-radical trans women about this election? I know a few that I haven’t spoken to since the 5th and while I’m super fucking jaded and don’t give a shit, I know that other trans women I know aren’t going to be taking this well. Any tips for not coming off like a flippant asshole?

    I had someone I’ve never talked to visibly confused on what pronouns to use for me. Is it literally just the longer hair???
