I love GitHub! It's a great site for collaborating and sharing useful information, code, and software tools! Some people have created some great study guides and reading suggestions for various software engineering specialisations. Here are some of mine that anyone could find useful!

This is the one I'm currently studying so I can personally vouch that this is a great collection of book recommendations for any aspiring games developer.

This is one that was recommended to me by a great web developer friend - it seems to cover pretty much everything you would ever want to know about web technologies!
What are some of ones you've comes across? Please leave a comment below with some of your own programming / coding / GitHub guide recommendations!
