Tomorrow's systems have space and energy constraints, as well as ever-increasing needs for reliability and responsiveness. These challenges are at the root of my motivation to evolve in the world of electronics and low-level programming.
My two favorite quotes:
"People who are really serious about software should make their own hardware" Alan Kay, 20 July 1982
"Debugging is like being the detective in a crime movie where you are also the murderer" Filipe Fortes, 10 November 2013
