Trans Megathread for the Week of November 4th, 2024 to November 10th, 2024

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'm a bit worried I'll never feel at home with a name ever again doggirl-gloom

    But I'll wait a couple weeks before fully dooming.

    • It was a little weird for me the first while, it's a new name, I wasn't used to it.

      My ears still perk up when my dead name is said (like referring to someone else lol), but the same thing happens with my actual name now too. It was a slow process, you get used to it, eventually you'll wake up and realize you've gone by your name for a few years and most of the people you talk to only refer to you with it and may only know you by that name.

      • I used to beat myself up about being weird around my deadname, now I just kinda live with it. 15 years since I changed it and still I get nervous around certain people because of their name

    • it took me a year and a half to settle on one and i'm still a little flighty about it sometimes.

      not reassuring i know, but you're not alone at least if that ends up being you too. i hope you find something though!
