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. :)

    If she’s literally just starting, they’ll start super low and go up. That’s what the WPATH says to do even if it’s not technically the most effective - WPATH is kinda stuck in the past, and they’re trying to base HRT regimes for trans patients on something other than vibes and which doctors you just happen to be near and can afford. It sucks but without a standard, you kind of have to doctor hop and just luck out. I dunno I’m of 2 minds on the whole thing.

      Interesting because they seemed to have done the opposite for me by giving me an unusually large dose and then cutting me back when my levels were unsurprisingly too high. Not that I’m complaining about getting good HRT right off the bat though
