Ask HN: Where are the best online programing courses?
Looking in particular for SQL and RStudio courses, but would be interesting to know where the best materials overall are these days, free or otherwise.
I was pretty underwhelmed by Coursera's Duke SQL course. For SQL, CodeAcademy is good. https://www.codecademy.com/catalog/language/sql For R, http://tryr.codeschool.com/ For RStudio, just download and explore. You'll learn the essentials of using it in no time. Thank you
