Ask HN: Favorite talks [video] on software development?

I'm (re)designing a course on software project management which has morphed into a survey of agile approaches, scrum, version control, DevOps, testing, and other pieces of the modern software development business. I'm looking for recommendations of videos (TED talks, conference presentations, lectures, whatever) that I can add to my syllabus as recommended viewing on each of these topics. Can y'all help me out with some recommendations?
