Cook rice in rice cooker with two eggs, when it's done I peel eggs and chop up some carrot/cucumber and eat it with Sriracha mayo. Impossible burger on a bun with Sriracha mayo and cucumber and corn chips on the side. Left overs, which are usually pretty good. Sometimes cheese pizza rolls.
Embedded Linux is such a huge part of embedded software in every industry. I've done a bit with build root but mostly Yocto. There is just no replacement for the Linux kernel. If I need to know how the kernel actually handles a platform driver, I can just look up the relevant source. This is just impossible with Windows (IoT or otherwise)
