Maybe they are finally taking a hint from Apple. Instead of Windows being an operating system, it could just be a gui over a Linux OS.
Is this an admission that Windows is unsuitable for this kind of work/market? An admission that Windows internal design and architecture does not lend itself to the design approach taken here? If so, what does that say about Windows long-term in an ever expanding market? That is, desktops, laptops, tablets, phones, watches, Internet-of-things? Makes it seem like Windows is this monolithic, unwieldy beast trapped in an ever more limited cage...
Microbloat doesn’t use its sandbox languages in their own work either. They write for WIN32 in c or c++ without MFC.
This should surprise no one. It sounds like a big deal but it’s a bit like saying that there is linux embedded in their thermostats in their buildings, or in their microwaves or refrigerators. And no - it’s not BSD - it’s linux.
