RailsConf 2014 - All the Little Things by Sandi Metz
Confreaks
Sandi Metz takes an ugly section of conditional code and refactors it into a few simple objects, bridging object-oriented theory and practice. The talk includes her take on the Gilded Rose refactoring kata and the idea that duplication is cheaper than the wrong abstraction.
HN treats it as a top-tier programming talk for learning refactoring and for the wrong-abstraction principle, recommended repeatedly over a decade.
