This was a presentation I gave to the University of Twente in early 2021. It's a case study of how simple, straightforward coding can turn several thousand lines of code and 10's of seconds of runtime into a few dozen lines of code and a subsecond runtime. It attempts to provide concrete examples of why software is often an order of magnitude (or more) slower than it should be.
