This episode is dedicated to tiny kernels driving operating systems also known as micro-kernels. While discussing the last 100 years of operating system design and implementation, our two aging heroes also shed some light on operating systems in general and their recent history (like fifty years). Unless you're a true OS nerd, you find the episode mildly refreshing and educational on the layers of software underneath your beloved applications controlling the hardware and other shenanigans. If you're an OS nerd, this episode may have the potential of closing your few remaining knowledge gaps (or something like this). A fun show for children of all ages and beyond.
