Huh, that's quite a dramatic code size reduction. Which percentage of this codebase was in tests and boilerplate code for stuff like helper data classes?
Current version of Windows already have Chromium in the form of new Edge and Microsoft seems to start pushing progressive web applications. At least they made good integration with system for them.
So, perhaps, soon we will have PWAs instead of bunch of electron apps each carrying its own Chromium.
>Are there already atmosphere-breathing engines that do this and what are they called?
Generally this kind of engine is called Magnetohydrodynamic drive. I'm not sure about atmospheric engines, but according to wiki[1] there are prototypes that uses water as working fluid.
МЦСТ (MCST) was an abbreviation for "Московский центр SPARC-технологий", now it's just a meaningless letters. ARM in computer name means probably "Автоматизированное рабочее место" - "Automated workstation"
