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. :)

    Don’t get old

    spoiler

    When I reflect on it was cute when I flipped out that being old is finding a gray body hair, nah fam its when your body comes down with the violence on multiple fronts. Like hemorrhoid burst and kidney stone passing in the same day (today was that day), and all those remedies people say work? Wistful thinking until it happens.

    I haven’t been OCD obsessing about tasks at work for a while, not sure what’s getting to me. Can’t do an NG, can’t start an IV without ruminating over it infiltrating or NG going into the lungs

    Feeling awful. I can barely focus or socialize. Scared of needles so I feel like I have to put starting T off or find another way to find it that doesn’t use a method that requires a needle. Don’t pass at all since my voice in person is high-pitched. Dreadful.

    wtf

    I kinda want to ask my friend out (i’ve accepted that her calling me very cute was probably not just platonic), but I feel bad about it.

    The thing is I’ve usually met this friend with another friend when we’ve hung out. We only met 1 on 1 last weekend because both of us happened to be free while the third girl wasn’t. We’ve even talked about a place we want to go, but if I ask her to hang out with just me, part of me feels like I would be ditching the other friend and going behind her back. doggirl-gloom
