This show is about programming on a Raspberry Pi with on operating
system or libraries.  In this programming environment, the only software
that the CPU executes is the software that you write.  This episode
introduces how to configure the build environment and get a basic
application up and running.  From here one can leverage these techniques
to build more sophisticated applications and deepen ones knowledge of
systems programming.

Here is some of the source material that I used while working on this
little learning experience.
