I recommend two talks by Laurie Voss of npm. They're a brain dump / quick overview of lots of random topics. The idea is things software engineers are expected to know but are rarely told. He's a good speaker, and there's lots of good information. The first video has poor sound quality for the first 5-10 minutes.
