We learned to install our OS onto Elbrus systems in an almost user-friendly manner, not only to just boot it, over this year. Quite a feat given that ALT is the third known operating system to run on e2k! Альт на Эльбрусе: путь к дистрибутиву Михаил Шигорин

Moscow State University CMC department basic course «Computer Architecture and Assembly Language» has two official implementations: one pretty outdated (16bit based) and one too complex (x86_64 based). In pursuit of simplicity, actuality and practical support we have developed, approved and used a course based on MIPS32 architecture using MARS simulator as practice platform, along with semi-authomatic homework verification. Although successful, this approach opened a list of technological challenges, like to implement some modern features in simulator or develop an illustrative tool showing that features at real hardware Инструментальная поддержка преподавания дисциплины «Архитектура ЭВМ и язык ассемблера» на ВМК МГУ George Kouryachy

Apertis is a Debian-derived platform for infotainment in automotive vehicles. Being a Debian derivative, Apertis doesn’t use typical Debian infrastructure software, so a infrastructure to build it had to be created using Jenkins, Open Build Service and other tools to provide continuous integration and package and image builds. Having managed the build infrastructure of Apertis for some time, I’m going to share my experience about the challenges of working on it, and how we solve issues we are confronted with.

Debos is a tool to make creation of various debian based os "images" simpler. While most other tools focus on specific use-case, debos is more meant as a toolchain to make comon actions trivial while providing enough rope to do whatever tweaking that might be required behind the scene.
