You mentioned several different topics which would take a long time to learn. I could help you with a Ruby path: - Learn the basics of Ruby (what's happening behind the API) - Learn the basics of Rails (what's happening behind the API) - Read Ruby under a microscope (what's going on closer to the hardware) - Learn the basics of cloud computing (AWS for example for the more arcane aspects of network infrastructure) You could pick other language and find similar resources for those. Also there's ton of material out there for all of these topics. Good luck.
