Lots and lots of C. (I'm mostly an embedded C programmer these days). Some C++ for a bit of higher-level "business logic" that benefits from a class-based approach, but a fairly limited subset of "modern" C++.
I'm addicted to low-level "embedded" type work. But all I hear back from are Django, RoR, $HOT_JS_FRAMEWORK, DevOps teams/recruiters.
Is there some buzzword or special topic to know and do a project in? Any suggestions for projects to display on GitHub, topics to know through and through (domain specific knowledge)?
I sit at work thinking all day about RasbPi sensor projects sitting on my workbench collecting dust due to job+young kids.
