JSConf - Videos from JSConf
AngularJS - Official AngularJS channel
CS 50 - Harvard University's introduction to computer science and the art of programming. A must follow for beginners!
Front End Center - This guy makes really good videos on Front-end topics, doesn't post very frequently though.
TheNewBoston - Tons of programming videos and tutorials, I remember learning PHP from this channel in my early days, this guy Bucky makes everything really interesting and fun 😄
