In designing these dev tools I'll strive to make the software easy to study & (minor caveats) modify on-device, whilst hindering the ability for others (whom you interact with over the internet) to claim that control for themselves.
I won't extend the hardware to aid implementing these dev tools, since they're not the main point of the device. Though at times I will discuss "clever hacks".
3/3 Fin for today! Tomorrow: Introduce compilers & code-runners.
