Hackr.io Is a Crowdsourcing of Programming Classes
We’ve seen many collections of different programming classes and resources before, but Hackr.io makes a little difference by allowing users to submit their own choices and vote for others.
The resources here cover everything from C ++ to Google Analytics. The point is to collect as many resources as possible in one place, which you can also add if you like. This is a great starting point if you’re looking for tutorials or just want to share what you already know.
