As youtube replaced TV, for the most part, there are several channels that I follow that have great topics for developers in general, if you are starting or not.
5- justforfunc. Francesc Campoy is a really awesome Go developer that use to work at Google. His main focus is Go, but you can follow him even if you don't use Go, because he has a very straightforward approach and very good coding practices.
4- sentdex. If python is your thing, you definitely need to check out this channel. With a very solid way of teaching things, he can teach you from simple Python to Machine Learning using pure Tensorflow.
1- The Coding Train. If I give Dan a quarter for each time I learn something new from him, he would be a millionaire by now. This NY ITP teacher has a focus on creative coding, but he covers a lot of different algorithms in both JS and Processing (Java API).
