Engineering a Sort Function (1993) [pdf]

  Really cool to see an "old-school" analysis of a classic algorithm and it's implementation. Today with all of the "advanced features" provided by languages and libraries, it's easy to get lost in minutiae and implementation details; for example, how C++ uses templates to specialize sorts for different types. It's refreshing to see a clean, well-thought-out implementation of a core algorithm and a careful examination of the various trade-offs it represents.

  This is totally unrelated but the pdf does not show correctly on my chrome browser (linux), with letters running everywhere. It looks right in evince after download.

  If you're interested in these types of implementation/optimization details, Andrei Alexandrescu gave a great talk at this year's CppCon about practical sorting, e.g. when to break out of quicksort to something else: https://www.youtube.com/watch?v=FJJTYQYB1JQ https://www.youtube.com/watch?v=FJJTYQYB1JQ

    Thanks for this recommendation. It pushed me to finally watch it and I found it to be a really nice talk.
