This reminds me a lot of Handmade Hero. https://www.youtube.com/user/handmadeheroarchive https://www.youtube.com/user/handmadeheroarchive For educational purposes, Casey Muratori codes a complete game from scratch, pretty much without any libraries (Win32 and OpenGL). In one of the videos he said that he doesn't use the internet at work. Hates it. When he has a question, he writes it down. When he needs to learn something, he googles it at home, downloads a bunch of articles as PDFs, then goes through them at work, but offline.
