Casey Muratori's University of Twente guest lecture is a case study in how straightforward code can cut thousands of lines and tens of seconds of runtime down to a few dozen lines running in under a second.

HN people recommend it to anyone wanting a practical sense of what CPUs can really do and why abstraction layers cost so much performance.
