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. :)

    hi hello

    cw election

    my friend lives in long island, she is trans, latina, and disabled. she has guaranteed money, enough to live on in most cities except those like nyc and San Francisco, because of a birth injury. she’s extremely scared of this new trump government and project 2025. she’s also adhd and has trouble making decisions. should i encourage her to move away from America? what should I say to her? I’m not sure how dangerous it will be for her but she already hates long island. she either wants to move to montreal, where I and some friends live, or Spain where she has a cousin and aunt that she doesn’t know too well. montreal would come with the issue of getting a visa but we could figure a way. she puts a lot of trust in me and I don’t want to encourage her to move here for selfish reasons (i want my friends to live near me). thank u in advance

    someone reply to my reply in this chain please and thank you

        it’s more like… the issue is because of the nature of the visa she would be dependent on someone else (probably me) to get permanent residency by living together a year. also she’s my ex. so there’d be a really fucked power dynamic. we could probably get a really big apartment with lots of rooms

          it’s not a fucked power dynamic unless you do something untoward with it. idk sometimes people have to put themselves at the mercy of others. all we can hope is those others are kind and not looking to take advantage. if that’s you then i’d say go for it.

            aside

            Thank you for saying this… I obsess over “power dynamics” and “awkwardness” etc but I have this extreme desire to help the people that matter to me any way I can despite all that. It really should be simple, shouldn’t it? Someone needs help, we have a little bit of means, so we help.

              shared concerns

              i completely understand. i think it can be a strength actually! obsessing over those things means you can be aware of them and account for them, rather than letting them sneak up on you and potentially destabilize the situation. personally i find precious little in life is simple, but i can say that i have never regretted offering help, even when it ended badly (which has been thankfully rare). imo, if you have the desire you simply have to let it lead. “i wish i had helped when i had the chance” is the stuff regrets are made of.

              anyway, i hope everything works out for your friend, no matter how it shakes out. trans-heart

                I need to frame this. Thank you so much for your kind words, I can’t overstate how much they mean to me as someone who had kind of a complex about this…
