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. :)

    No to both

    A crush isn't something I've had properly since I was much younger. I still remember being 18 and lovestruck and it was like the whole world was singing and it was a new feeling and I stumbled over my words and felt butterflies, haven't had that for a while.

      You're literally in the perfect profession for a romance novel!

      You heal a patient's broken body, and they heal your broken heart! badeline-scream

        The nurse with patient romance thing is absolutely a classic, it even has a name Florence Nightengale Syndrome lol

        IRL, I can't have a relationship with any patient Ive seen for at least 2 years (and I'm a pediatrics nurse anyway). You lose your license and get put on the shit list, they put your face and why you're on the shit list online. Most people get it for accessing patient info improperly, but every once in a while you see an inappropriate relationship

          Omfg you two would keep journals about your time apart and set a time two years after their last appointment to meet and share what's happened!!! But one of you doesn't show up, and that's where the drama ensues!!! Why didn't they show up? Did they lose interest? NO! Their journal only shows love! So what happened?? A mystery!

          screm-aaaaa

          (I'm ignoring the pediatrics part. It doesn't read well)

            There was a cute guy once, he seemed decent. He was in on the CIWA protocol (alcohol withdrawal) but I didn't hold it against him. I think he passed away though 😬 yeats later, of complications relating to... well you know...
