The list has everything you would want to get started on website development or programming in general. You can browser through some awesome open source projects, or if you have been in the industry for long, you may want to contribute to some of the projects or the list that user sindresorhus has created.
My personal favorite is awesome user scripts. The repo has list of scripts that would take your browser to another level. However, be careful on what you install, some of the scripts may be harmful.
Another one of my favorites is books section. Do check it out, you may find some of the books interesting. Another tip, if you are interested in buying any of the books listed there, do check out your local library catalogue, you might be able to borrow it for free.
I hope this git repo would help you learn some interesting stuff that you didn’t know was out there.
