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. :)

    I don't know if they even keep the info of who changed their gender marker tbh, they might just update it the database and away they go. Even before I cracked my egg, I had "mistakes" with my gender marker on some government file and hospital stuff (perhaps not mistakes but prophetic warnings to trans my gender). I imagine this happens with cis people occasionally, and if they cancel any of their passports over it people would be PISSED. Although they might decide it's like an Imane Khalif situation and retroactively decide they must be trans.

    I'm sure they could try to say you must put your birth sex on your passport, but if you get that amended... I don't think they have any way of undoing your preferred gender marker. In the future, we should aim to degender a lot of these IDs. It doesn't matter and we don't need them on our drivers license, it's no one's business on our birth certificates (I can see it on a notice of birth but then they should ignore it on gov ID). It's nice when I look at some ID and see F, for sure, but it'd be better if it didn't say anything at all. Don't need the government certifying my gender.

      I think with digital systems that it'd be possible to audit, but it wouldn't be a straightforward process I agree.

      I think that if I got it updated, that I'd need to do a F marker as opposed to an X marker, as it would be pretty simple to flag those passports.

          Seems like a bad idea now
